Description
Technical Field
The application relates to the field of laser printing, in particular to a pressing piece or a pressing assembly applied to an electronic imaging device.
Background
In the related art, the process cartridge is detachably mountable to the electronic image forming apparatus. The electronic imaging device is internally provided with a driving unit for outputting a rotational driving force. The process cartridge generally includes a power receiving unit, a developing unit, a developer, a powder controlling unit, and a housing accommodating the above units, and is additionally provided with a photosensitive unit, a charging unit, a cleaning unit, a stirring unit, and the like, according to different kinds of cartridge structures. The power receiving unit of the processing box is axially arranged at one end of the processing box along the developing unit, and is meshed with the driving unit in the electronic imaging device through the power receiving unit so as to transmit the rotating driving force into the processing box, and finally, the rotating unit (such as the developing unit, the photosensitive unit, the stirring unit and the like) in the processing box is driven to rotate so as to participate in the developing work of the electronic imaging device.
Before performing a developing operation (so-called "printing") in an electrophotographic image forming apparatus, a user needs to mount a process cartridge in the electrophotographic image forming apparatus, and a power receiving unit of the process cartridge needs to be brought into contact with a driving unit on the electrophotographic image forming apparatus to be engaged with each other.
Fig. 1 and 2 are schematic structural views of a driving unit in which a process cartridge is not mounted in an electronic image forming apparatus in the related art. As shown in the drawing, a driving unit 1080 is provided in an electronic image forming apparatus (not shown in the drawing), wherein the driving unit 1080 has a power transmission member 1080e for transmitting a rotational driving force to the process cartridge. Specifically, the supported portion 1080g of the driving unit 1080 is supported by the supporting portion 1085a of the supporting member 1085, and further, the first contacted portion 1080h is abutted against the first contact protrusion 1004 provided in the electronic imaging device, while the pressing member 1003 applies the urging force FF2 to the pressed portion 1080i of the driving unit 1080 by the spring 1006 so that the second contacted portion 1080j is contacted with the second contact protrusion 1005, and at this time, the driving unit 1080 is in the initial position, and the axial direction EE of the driving unit 1080 is inclined with respect to the center RR of the supporting portion 1085a as viewed along the direction of the axis of the supporting member 1085 parallel to the direction of the arrow HH.
When the process cartridge is mounted in the electronic imaging device, the power receiving unit and the driving unit 1080 come into contact, so that the driving unit 1080 is shifted from the tilted state in the initial position to be parallel to the axial direction of the support 1085 to be successfully in mating engagement with the power receiving unit to transmit the driving force.
However, structural interference is generated between the power receiving unit and the driving unit 1080 in the process of contact engagement, so that the power receiving unit and the driving unit 1080 are difficult or impossible to engage with each other precisely and transmit power, and therefore, a certain time is required for engagement of the power receiving unit and the driving unit 1080, and the working efficiency of the process cartridge is also affected.

When the process cartridge is mounted in the electronic image forming apparatus, the power receiving unit of the process cartridge comes into contact with the driving unit 1080, so that the driving unit 1080 is shifted from the tilted state in the initial position to be parallel to the axial direction of the support 1085 to be successfully matingly engaged with the power receiving unit to transmit the driving force.
However, structural interference is generated between the power receiving unit and the driving unit 1080 in the process of contact engagement, so that the power receiving unit and the driving unit 1080 are difficult or impossible to engage with each other precisely and transmit power, and therefore, a certain time is required for engagement of the power receiving unit and the driving unit 1080, and the working efficiency of the process cartridge is also affected.
Example 1
An embodiment of the present application provides an electronic imaging device, which includes a process cartridge 1, a driving unit 1080 and a driving unit protecting cover 1081, where the driving unit protecting cover 1081 is covered outside the driving unit 1080.
The electronic image forming apparatus may be a printer, a copier, a scanning-copying all-in-one machine, or the like, and is not limited herein. The following description will be made by taking a printer as an example. The process cartridge may be a toner cartridge, an ink cartridge, or the like.
The processing box generally comprises a powder bin unit and a waste powder bin unit, wherein the powder bin unit comprises a developing roller, a powder outlet cutter, a powder feeding roller, a stirring frame and the like, and the waste powder bin unit comprises a photosensitive drum, a charging roller, a cleaning scraper and the like. The process cartridge also typically contains a developer, and a power receiving unit that receives an external driving force, the power receiving unit including a drive head and a drive gear provided at one end of the photosensitive drum. Further, the process cartridge is also provided with a positioning member that cooperates with the machine. The developing roller rotates under the driving action to drive the developer to be transferred onto the photosensitive drum. The powder outlet knife can adjust the uniformity of the developer on the developing roller. The stirring frame can loosen the developer in the powder bin unit. The charging roller charges the photosensitive drum, and the cleaning scraper cleans the redundant developer after developing on the photosensitive drum.
Fig. 3 is a schematic view of the structure of the process cartridge of the present application. As shown in fig. 3, the process cartridge 1 includes a cartridge body a10, a photosensitive drum 20, a developing roller 30, and a power receiving unit 21, the cartridge body a10 containing developer therein, the photosensitive drum 20 and the developing roller 30 being rotatably provided to the cartridge body a10. The power receiving unit 21 is provided at one end of the casing a10 and connected to the photosensitive drum 20 for engagement with a driving unit of the electronic imaging device to receive a driving force output from the driving unit of the electronic imaging device.
Specifically, the cartridge a10 includes a holder a11, the holder a11 may be a photosensitive drum frame, the holder a11 includes a first fixing post a111 and a through hole a112, and the power receiving unit 21 is fixed to the holder a11 through the through hole a112 and exposed to the outside of the through hole a112 to receive the driving force output from the driving unit 1080. The first fixing post a111 is disposed above and/or in front of the power receiving unit 21 with respect to the axial direction of the photosensitive drum 20.
In order to change the driving unit 1080 from the tilted state of the initial position to the horizontal state capable of being engaged with the power receiving unit 21, the process cartridge 1 further includes a pressing member a40, wherein the pressing member a40 is fixedly disposed on the cartridge body a10 and located at the same end of the cartridge body as the power receiving unit 21, and is used for pressing the driving unit 1080 during the installation of the process cartridge 1, so that the driving unit 1080 is aligned.
Further, the urging member a40 is detachably mounted on the first fixing post a111 so as to be fixed to the bracket a11, while at least a portion of the urging member a40 is located outside the power receiving unit 21 in the axial direction of the photosensitive drum 20. Optionally, the pressing element a40 is configured as a roller, and the outer surface of the roller is a guiding pressing surface, and the guiding pressing surface can guide and press the driving unit, so that the driving unit is aligned. Further, the outer surface of the roller may be coated with a rubber coating, by which it is possible to avoid the driving unit from wearing out due to structural interference when the pressing member a40 contacts the driving unit 1080.
Fig. 4 to 6 are schematic views showing a process of contact engagement of the power receiving unit of the process cartridge with the driving unit of the electrophotographic image forming apparatus in the present application. As shown in fig. 4, when the process cartridge 1 is mounted in the electrophotographic apparatus in the Y1 direction, the pressing member a40 fixed to the frame is also gradually moved toward the driving unit 1080 along with the movement of the process cartridge, when the pressing member a40 contacts the driving unit 1080 to form structural interference, the pressing member a40 applies a pressing force F to the driving unit 1080, and the driving unit 1080 moves in a direction approaching the power receiving unit 21 after receiving the pressing force, so that the driving unit 1080 contacts the pressing member a40 to rotate the pressing member a40, and at the same time, since the pressing member a40 is fixedly mounted on the frame, the pressing member a40 is always kept parallel to the axial direction of the photosensitive drum 20 during the engagement of the power receiving unit 21 with the driving unit 1080, i.e., the distance of the pressing member a40 relative to the axis of the photosensitive drum 20 does not change. With the process cartridge 1 mounted in place, the driving unit 1080 is moved from the initial position to a position parallel to the axial direction of the supporting member a1085, at which time the urging member a40 is disposed above and/or in front of the power receiving unit 21 with respect to the axial direction of the photosensitive drum 20, and the final driving unit 1080 is successfully engaged with the power receiving unit 21, so that the driving unit 1080 transmits the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate.
In this embodiment, the pressing member is disposed on the process cartridge, and the driving unit 1080 is forced to move from the initial inclined position to a position substantially parallel to the axial direction of the photosensitive drum by the pressing member a40, and the projection of the pressing member is completely misaligned with the projection of the photosensitive drum in a plane perpendicular to the axial direction of the photosensitive drum, so that the contact and engagement process of the power receiving unit and the driving unit can be smoother, the contact and engagement time of the power receiving unit and the driving unit is greatly saved, and the working efficiency of the process cartridge is improved.
Example two
In this embodiment, another process cartridge is provided, and the unspecified parts are the same as those of the process cartridge of the first embodiment.
As shown in fig. 7 and 8, the process cartridge 1 further includes a movable positioning member B50, the positioning member B50 being movably disposed at the same end of the frame B11 as the power receiving unit 21, and the positioning member B50 being capable of being displaced in a first direction with respect to the frame B11, wherein the first direction is a height extending direction (Z direction in fig. 8) of the process cartridge. Further, the bracket B11 is provided with a chute B15, and the chute B15 may be a rectangular chute or a circular chute, or a chute with other regular or irregular structures, which is not limited herein. The positioning element B50 is slidably disposed in the chute B15, so that the positioning element B50 can move along the chute B15 relative to the box body.
When the process cartridge 1 is mounted into the inside of the electronic imaging device through the mounting rail B900 of the inside side of the electronic imaging device in the advancing direction (mounting direction of the process cartridge), the positioning member B50 is supported by the mounting rail B900 of the inside side of the electronic imaging device and moves forward along the mounting rail B900. Since the positioning member B50 is movable relative to the casing, and the positioning member B50 is supported on the mounting rail B900 during the mounting process, the casing of the process cartridge 1 can be displaced to a certain extent relative to the mounting rail B900 of the electronic imaging device during the mounting process of the process cartridge 1, and the pressing member B40 located at the end of the casing can also be moved to a certain extent (at least up-down movement can be realized) relative to the driving unit 1080 or the mounting rail B900 of the electronic imaging device along with the overall movement of the process cartridge 1, by which the pressing member B40 can be moved to a certain extent relative to the driving unit 1080, and the process cartridge can be moved downward to press the driving unit 1080 after being mounted in place, so that the driving unit 1080 is engaged with the power receiving unit 900 substantially coaxially to transmit the driving force. And the urging member B40 urges the driving unit 1080 from the initial inclined position to a position substantially parallel to the axial direction of the photosensitive drum, and in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the urging member is completely misaligned with the projection of the photosensitive drum.
In this embodiment, due to the positioning member B50, the pressing member B40 is installed in the process cartridge 1 into the electronic imaging device, the positioning member B50 can move along the chute B15 relative to the cartridge body and drive the pressing member B40 disposed on the cartridge body to move relative to the cartridge body, that is, the pressing member B40 can obtain a certain movement amount, so that the pressing member B40 installed on the process cartridge 1 can more easily press the driving unit 1080 to avoid mutual interference.
In addition, the technical solutions of the first embodiment and the second embodiment may be combined with each other, for example, the movable positioning member of the second embodiment is applied to the process cartridge of the first embodiment, so that the process cartridge of the first embodiment is easier to achieve the engagement between the power receiving unit and the driving unit, and the embodiments are not mutually exclusive.
Example III
The present embodiment provides another pressing member, which is a further improvement based on the second embodiment, and the non-illustrated portions are the same as those in the foregoing embodiments, so that the description is omitted for brevity.
As shown in fig. 9 and 10, the process cartridge 1 further includes a movable positioning member C50 and an elastic telescopic member C60, the positioning member C50 is disposed on the bracket C11 and located at the same end of the cartridge body as the power receiving unit 21, and the positioning member C50 is connected to the bracket C11 via the elastic telescopic member F60, so that the positioning member C50 can move relative to the process cartridge body. The process cartridge 1 further includes a pressing member C40, wherein the pressing member C40 is connected to the support frame C11 through a connecting rod C70, and specifically, the pressing member C40 is a gear, and an outer surface of the gear is a guiding pressing surface.
When the process cartridge 1 is mounted into the inside of the electronic imaging device through the mounting rail C900 of the inside side of the electronic imaging device in the advancing direction (mounting direction of the process cartridge), the positioning member C50 is supported by the mounting rail C900 of the inside side of the electronic imaging device and moves forward along the mounting rail C900. Since the positioning member C50 is movable relative to the process cartridge 1, and the positioning member C50 is supported on the mounting rail C900 during the mounting, the process cartridge 1 can be moved by a certain amount relative to the mounting rail C900 of the electronic imaging device during the mounting of the process cartridge 1.
Specifically, in the process of mounting the process cartridge 1 to the electronic imaging device, the pressing member C40 first touches the stopper wall 1081 provided at the outer periphery of the driving unit 1080, so that the entire process cartridge is moved upward with respect to the mounting rail C900, avoiding high points in the mounting process, and when the process cartridge is completely mounted in place, the process cartridge is also moved downward to a prescribed position, and in the process of moving the process cartridge downward, the pressing member C40 provided in front thereof also achieves a certain movement amount (at least up-down movement can be achieved) with respect to the driving unit 1080 inside the electronic imaging device or the mounting rail C900 of the electronic imaging device along with the entire movement of the process cartridge.
As shown in fig. 11 and 12, when the pressing member C40 fixed to the holder C11 gradually approaches the driving unit 1080 and comes into contact with the driving unit 1080 as the process cartridge moves, the gear portion C40a of the pressing member C40 is brought into structural interference and engagement with the gear portion C1081b of the driving unit 1080, and since the gear modulus of the pressing member C40 is slightly different from that of the driving unit 1080, after the two are engaged with a plurality of tooth shapes, the pressing member C40 and the driving unit 1080 come into top teeth while the pressing member C40 is fixed with respect to the process cartridge, and since the pressing member C40 is fixed with respect to the process cartridge, the driving unit 1080 can move from an initial inclined position to a position approximately parallel or coaxial with the axial direction of the power receiving unit 21 by the engagement with the pressing member C40, and in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member is completely misaligned with the projection of the photosensitive drum, and finally the driving unit 1080 is successfully engaged with the power receiving unit 21. Throughout the process, the distance of the pressing member C40 with respect to the axis of the photosensitive drum does not undergo displacement change.
In some embodiments, after the rotation of the driving unit 1080, the driving unit 1080 can be smoothly engaged with the power receiving unit 21.
Example IV
As shown in fig. 13, a block-shaped projection D1010 is provided on the side wall of the electronic imaging device, and the block-shaped projection D1010 is located above the driving unit 1080 or the mounting rail 900 (part) and within the mounting space of the process cartridge 1 in the electronic imaging device (refer to the mounting space of the process cartridge 1 of fig. 31). The rest of the non-illustrated parts may refer to the content of the foregoing embodiments, and are not repeated for brevity.
As shown in fig. 13 to 16b, this embodiment provides another pressing member in the process cartridge, in this embodiment, the pressing member D40 is fixedly provided on the process cartridge 1 or the pressing member D40 is integrally formed with the process cartridge and is located on the same side as the power receiving unit 21, and in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member D40 is completely misaligned with the projection of the photosensitive drum. The pressing member D40 includes a guide pressing surface D40a1 (inclined surface or arc surface), the guide pressing surface D40a1 is disposed at a side of a front end (mounting direction of the process cartridge 1) of the pressing member D40 toward the power receiving unit 21, and the guide pressing surface D40a1 is disposed corresponding to the block-shaped protrusion D1010. The installation process of this embodiment is as follows:
as shown in fig. 13 and 14a, when the process cartridge 1 is mounted in the electronic imaging device along the Y1 direction, the front end of the pressing member D40 corresponds to the block-shaped protrusion D1010 on the side wall of the electronic imaging device, and as the process cartridge 1 continues to be mounted and moved, the guiding pressing surface D40a1 of the pressing member D40 abuts against the block-shaped protrusion D1010, and the pressing member D40 moves upward and forward under the action of the guiding pressing surface D40a1 and the block-shaped protrusion D1010, and since the pressing member D40 is fixedly disposed on the process cartridge 1 or the pressing member D40 and the process cartridge are integrally formed, the upward movement of the pressing member D40 also drives the front end of the process cartridge 1 to move upward, so that the whole process cartridge 1 rotates in the counterclockwise direction (as viewed from the axial direction of the power receiving unit 21).
As shown in fig. 14b, with the continued mounting of the process cartridge 1, the pressing member D40 moves upward over the block-shaped protrusion D1010 and then moves above the blocking wall 1081, at which time the front end of the pressing member D40 is about to pass over the blocking wall 1081, and enters the opening position of the blocking wall 1081 to contact the driving unit 1080, as shown in fig. 15 a.
As shown in fig. 15b, after the process cartridge 1 is mounted in place in the electronic imaging device, the pressing member D40 is positioned above the driving unit 1080. One end 1A of the process cartridge 1, i.e., the end at which the power receiving unit 21 is located, is located more upward (the process cartridge 1 is partially tilted upward) in the electronic image forming apparatus than the other end 1B of the process cartridge 1, as viewed from the rear side of the process cartridge 1.
As shown in fig. 16a and 16b, as the door of the electronic imaging device is closed, the pressure lever D1020 inside the door presses down the upper surfaces 1C on the left and right sides of the back of the casing of the process cartridge 1, causing the overall process cartridge 1 to be stressed, the front end of the process cartridge 1 moves down and drives the pressing member D40 to move down, at which time the front end of the pressing member D40 presses down the driving unit 1080 to move down to be substantially coaxial with the power receiving unit 21 to receive the driving force. Since the power receiving unit 21 is coaxial with the driving unit 1080, the rear end lower portion of the process cartridge 1 rotates in the clockwise direction. In the case where the pressing lever D1020 applies pressure to both the left and right sides of the process cartridge 1, both ends (1A, 1B) of the process cartridge 1 are kept substantially horizontal.
In some embodiments, the process cartridge may also press the front end of the pressing member D40 down on the driving unit 1080 under its own weight, so that the driving unit 1080 moves downward to be substantially coaxial with the power receiving unit 21 to receive power.
Example five
The embodiment is further improved on the basis of the fourth embodiment, and the non-illustrated parts are the same as those of the fourth embodiment, as shown in fig. 17 a-18, the process cartridge further includes a limit guide E40b, an elastic member (not shown in the drawings), and a guide control member E40c, the limit guide E40b is movably disposed on the end cover of the process cartridge 1 and located at the same end of the cartridge body as the power receiving unit 21, and the limit guide E40b can generate displacement in the axial direction of the photosensitive drum. Specifically, the limit guide E40b may be a protrusion provided on the end cap of the process cartridge 1, for example, may be a cylindrical structure. The elastic piece is sleeved on the limit guide piece E40b, two ends of the elastic piece are respectively propped against the limit guide piece E40b and the inner wall of the end cover, and force pointing to the inside of the end cover is applied to the limit guide piece E40b through the elastic piece. The stopper guide E40b is kept in a retracted state on the end cover without being subjected to other external force, so that the end cover of the process cartridge 1 does not interfere with the inner wall of the electronic image forming apparatus during the process cartridge mounting.
The guide control member E40c may be a swing lever which may be disposed inside the end cap of the process cartridge 1, and the receiving portion of the swing lever is located at a rear position of the process cartridge, receives a force (described later) from the pressing lever E1020 (shown in fig. 18) through the receiving portion of the swing lever, and transmits the received external force to the limit guide E40b, for example, pushes the limit guide E40b out of the end cap to be in an extended state by means of a bevel fit or the like. The present embodiment is similar to the fourth embodiment in that the pressing member E40 is fixedly provided on the cartridge body or the pressing member E40 is integrally formed with the process cartridge, and the pressing member E40 is located above the driving unit 1080 when the process cartridge 1 is mounted in place in the electrophotographic apparatus.
Further, as the door of the electronic imaging device is closed, the pressure lever E1020 inside the door presses down the upper surfaces 1C on the left and right sides of the back of the casing of the process cartridge 1, so that the whole process cartridge 1 is forced. The front end of the process cartridge 1 moves downward and drives the pressing member E40 downward, at which time the front end of the pressing member E40 presses down the driving unit 1080, causing the driving unit 1080 to move downward to be substantially coaxial with the power receiving unit 21 to receive power. The urging member E40 urges the driving unit 1080 from the initial inclined position to a position substantially parallel to the axis direction of the photosensitive drum. And in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member E40 is completely misaligned with the projection of the photosensitive drum. Since the power receiving unit 21 is coaxial with the driving unit 1080, the rear end lower portion of the process cartridge 1 rotates in the clockwise direction. In the case where the pressing lever E1020 applies pressure to both the left and right sides of the process cartridge 1, both ends (1A, 1B) of the process cartridge 1 are kept substantially horizontal. Meanwhile, the pressing rod E1020 presses the guide control member E40c, so that the guide control member E40c moves in the direction of arrow R in the end cover, and further the limit guide member E40b that is originally in the state of retracting into the end cover extends out from the end cover (in the figure, the limit guide member E40b extends out perpendicular to the paper surface) through a bevel fit or the like. At this time, since the process cartridge is in the aligned state, the protruded limit guide E40b can be locked into a limit groove E1011 in the electronic imaging device, thereby limiting the mounted process cartridge to be less prone to shaking and stably participating in printing.
When the process cartridge is required to be taken out from the electronic image forming apparatus, the door is opened to lift the pressing lever E1020, and then, with the disappearance of the force applied to the guiding control member E40c, the elastic restoring force of the elastic member connected to the restricting guide E40b causes the restricting guide E40b to retract into the end cover, and at the same time, the guiding control member E40c can be returned to its state before the mounting thereof. Preferably, the pressing rod E1020 presses the upper surface 1C of the process cartridge 1 to align the process cartridge, and then the pressing rod E1020 applies force to the guide control member E40C, so that the limit guide E40b can extend to be locked in the limit groove E1011. This can be achieved by providing the pressure lever E1020 with different step surfaces along its travel direction, for example, a first step surface E1021 and a second step surface E1022 in sequence in the travel direction (arrow M) of the pressure lever E1020. When the door is closed to press the pressing lever E1020 into the apparatus, the first step surface E1021 presses the upper surface 1C of the process cartridge to cause the process cartridge to perform a centering operation, and then with further pressing of the pressing lever E1020, the second step surface E1022 comes into contact with the force receiving surface of the pressing guide control member E40C, so that the limit guide E40b can extend into the limit groove E1011. The guide control member E40c is not limited to be provided inside the end cover, but may be provided outside the process cartridge, and is not limited thereto.
Example six

As shown in fig. 22 to 24, the process cartridge 1 further includes a hub F60, a movable member F50, a connecting member F70, and a first elastic member F90. The power receiving unit 21 is provided with an engagement portion F213 and a connection hole F211 for engagement with the driving unit 1080, and an abutment surface F212 extending outward along the axis of the power receiving unit 21 is provided between the engagement portion F213 and the connection hole F211.

The outer circumference of the hub F60 is provided with a gear portion, and the inside of the hub F60 is also provided with two supporting portions F61 provided at intervals.
As shown in fig. 25 and 26, the assembly relationship of the above-mentioned individual parts is: the movable member F50 is movably disposed in the hub F60, such that the lower surface F54 of the movable member F50 abuts against the support portion F61 of the hub F60; the power receiving unit 21 is fitted into the movable member F50 through the through hole F52 of the movable member F50, at which time the abutment surface F212 (fig. 22) of the power receiving unit 21 abuts against the upper surface F53 of the movable member F50, so that the power receiving unit 21 is fixedly supported on the movable member F50 and is movable together with the movable member F50 with respect to the hub F60; the connecting member F70 passes through the connecting hole F211 of the power receiving unit 21, and both ends of the connecting member F70 are placed in the supporting portion F61 built in the hub F60 to drive the hub F60 to rotate after the power receiving unit 21 receives the driving force from the driving unit 1080; the first elastic member F90 is disposed in the hub F60, and one end of the first elastic member F90 abuts on the bottom surface of the hub F60, and the other end of the first elastic member F90 abuts at both ends of the connecting member F70.
The above parts are mutually matched and then can be integrally assembled to one end of the photosensitive drum 20, so that the hub F60 can drive the photosensitive drum 20 to rotate after receiving the driving force and transmit the driving force to the developing roller gear 31 through the gear part of the hub F60, and further drive the developing roller 30 to rotate. The bracket F11 covers the movable member F50, and the power receiving unit 21 and the protrusion F51 on the movable member F50 are exposed outward through the bracket F11. The pressing piece F32 is movably connected with the bracket F11 through a second elastic piece F80, specifically, the pressing piece F32 and the second elastic piece F80 are respectively installed in a groove F110 of the bracket F11, one end of the second elastic piece F80 is connected with a first end F111 of the groove F110, the other end of the second elastic piece F80 is connected with a connecting post F321 of the pressing piece F32, and optionally, the second elastic piece F80 can adopt a spring or a pressure spring. In order to fix the pressing member F32 to the bracket F11, the fixing member F31 is fitted into the groove F110 by the rib F312 and covers a portion of the pressing member F32, and a plurality of screws (not shown in the drawing) sequentially pass through the plurality of fixing holes F311 and the plurality of fitting holes F113, thereby fixing the fixing member F31 and the bracket F11 to the cartridge body to prevent the control mechanism F30 and the power receiving unit 21 from coming out of the process cartridge 1.
The process of contact engagement and disengagement of the power receiving unit of the process cartridge and the driving unit of the electrophotographic image forming apparatus will be described below (for convenience of understanding of the operation of the pressing member F32 in the frame F11, the fixing member F31 in the control mechanism F30 is not shown in fig. 25).
As shown in fig. 25 and 26, when the process cartridge 1 is not mounted in the electrophotographic apparatus, the elastic force of the second elastic member F80 brings the pressing member F32 into an extended state, the pressing portion F323 of the pressing member F32 abuts against the projection F51 of the movable member F50, and applies a force to the projection F51 toward the inside of the photosensitive drum 20, so that the movable member F50 is compressed in the frame F11 together with the power receiving unit 21 against the elastic force of the first elastic member F90, and the engaging portion F213 of the power receiving unit 21 is not extended from the frame F11, at which time the power receiving unit 21 is in the initial position.
As shown in fig. 27 and 28, when the process cartridge 1 is mounted in the electronic imaging device in the mounting direction X6, the front end of the pressing member F40 abuts against the blocking wall 1081, and as the process cartridge 1 is further mounted, the pressing member F40 is inserted into the opening of the blocking wall 1081 to be in contact with the driving unit 1080, and since the front end of the process cartridge 1 moves downward and drives the pressing member F40 to move downward, the front end of the pressing member F40 presses down the driving unit 1080 at this time, causing the driving unit 1080 to move downward to be substantially coaxial with the power receiving unit 21 to receive power. Meanwhile, in the process of pressing the driving unit 1080 by the pressing member F40, the pressing member F32 abutting against the protrusion F51 moves to a position contacting the blocking wall 1081, and with the process cartridge mounted, the pressing member F32 is moved against the elastic force of the second elastic member F80 in a direction opposite to the mounting direction X6 by the force of the blocking wall 1081, at this time, the pressing member F32 no longer abuts against the protrusion F51, and the movable member F50 loses the force of the pressing member F32 to drive the power receiving unit 21 to move together in the Y6 direction (i.e., a direction away from the inside of the photosensitive drum), and at the same time, the lower surface F54 of the movable member F50 is no longer in contact with the supporting portion F61 of the hub F60, at this time, the power receiving unit 21 is in the second position. When the process cartridge is mounted in place in the electrophotographic apparatus, the pressing member F40 successfully aligns the driving unit 1080 and the power receiving unit 21 protrudes from the frame F11 to engage with the driving unit 1080, thereby achieving transmission of driving force.
As shown in fig. 29, when the process cartridge is required to be taken out of the electrophotographic image forming apparatus after use, the user may pull out one end 1B of the process cartridge 1 first, so that one end 1B of the process cartridge is inclined with respect to the other end 1A of the process cartridge 1 (i.e., the end where the power receiving unit 21 is located), and in a state in which the process cartridge 1 is relatively inclined, the power receiving unit 21 and the driving unit 1080 generate a certain clearance space, and at this time, the pressing member F32 gradually moves in the X6 direction to a position to come back into abutment with the protrusion F51, so that the movable member F50 drives the power receiving unit 21 to move in a direction directed toward the inside of the photosensitive drum 20, and finally the power receiving unit 21 and the driving unit 1080 are disengaged, so that the process cartridge is successfully taken out of the electrophotographic image forming apparatus.
In some embodiments, the first end 1A of the cartridge 1 is further provided with a guide surface F44, the guide surface F44 being located at the rear side of the pressing member F40, by which guide surface F44 interference with the block-shaped protrusion D1010 can be avoided during mounting and dismounting of the cartridge 1. Alternatively, the guide surface F44 may be provided as an inclined surface or curved surface inclined to the rear of the cartridge, and the block-shaped protrusion D1010 may slide against the surface of the guide surface F44 during mounting and dismounting of the cartridge, thereby avoiding interference between the cartridge and the block-shaped protrusion D1010 and thus affecting mounting of the cartridge.
In some embodiments, the first end 1A of the process cartridge 1 is further provided with a guided portion F41, and in particular, the guided portion F41 may protrude outward from an end surface of the process cartridge to be capable of abutting against a guide rail on the electronic image forming apparatus during the process cartridge mounting to guide the process cartridge mounting. Alternatively, the guided portion F41 may be provided at another position of the first end as long as it can abut against and be guided by a guide rail on the electronic imaging device, and of course, the guided portion F41 may be omitted in some embodiments.

On the basis of the sixth embodiment, this embodiment provides another process cartridge.
As shown in fig. 30 to 34, the process cartridge 1 includes a holder G11, a photosensitive drum 20, a pressing member G40, a movable member G50, a supporting member G60, a power receiving unit G21, and an elastic member (not shown in the drawings). Note that, in the present embodiment, the pressing member G40 is the same as the pressing member in the sixth embodiment, and the pressing member G40 is fixedly disposed on the case and is located at the same end of the case as the power receiving unit G21.
Specifically, the power receiving unit G21 includes a cylindrical main body G212, one end of the main body G212 is provided with an engagement portion G211 engaged with the driving unit 1080, the circumferential surface of the main body G212 is also provided with a plurality of connection posts G213 at even intervals, the number of the connection posts G213 is not limited, and in this embodiment, the number of the connection posts G213 is three. The outer circumference of the movable member G50 is provided with a gear portion, specifically, the movable member G50 is further provided with a limiting portion G51, and one surface of the limiting portion G51 is provided with a plurality of protrusions G52. The support member G60 has a cylindrical structure, and the support member G60 includes an upper cylinder G63 and a lower cylinder G64, the radius of the upper cylinder G63 is smaller than that of the lower cylinder G64, the outer circumferential surface of the upper cylinder G63 is provided with a plurality of grooves G65 corresponding to the number of the protrusions G52, the lower cylinder G64 is further provided with a support surface G61, and the support surface G61 is provided with a plurality of inclined surfaces G62 protruding outwards corresponding to the number of the protrusions G52.
As shown in fig. 36 and 37, the connection relationship between the above-described components is: the movable member G50 is sleeved on the upper cylinder G63 of the support member G60 to be mounted in the support member G60, the protrusion G52 is located on the support surface G61, and the movable member G50 can rotate and perform translational movement with respect to the support member G60. The power receiving unit G21 is disposed through the movable member G50 and the supporting member G60, and the connecting post G213 is disposed through the groove G65, and the connecting post G213 is supported by the limiting portion G51 of the movable member G50, so that the power receiving unit G21 is movably connected with the supporting member G60, and the power receiving unit G21 can move together with the movable member G50. An elastic member (not shown) is disposed between the power receiving unit G21 and the support member G60, and one end of the elastic member abuts against the power receiving unit G21 and the other end abuts against the bottom surface in the support member G60.
Further, as shown in fig. 35, in order to enable the translational movement of the power receiving unit G21 in the axial direction of the photosensitive drum 20, the process cartridge 1 further includes a control mechanism G30, the control mechanism G30 being engaged with the movable member G50 for controlling the rotation of the movable member G50 so that the power receiving unit G21 can be displaced in the axial direction of the photosensitive drum 20. Specifically, the control mechanism G30 includes a connecting member G31, an intermediate gear G32, and a driving gear G80, wherein the intermediate gear G32 is connected to the connecting member G31, and in this embodiment, the intermediate gear G32 and the connecting member G31 are integrally formed. The driving gear G80 may be sleeved on the other end of the connecting piece G31, and optionally, the driving gear G80 may also be a rubber wheel. When the control mechanism G30 is mounted to the cartridge body, the end of the connecting member G31 provided with the intermediate gear G32 is provided near the developing roller 30, and the intermediate gear G32 can be engaged with the gear portion of the movable member G50, and by the rotation of the control mechanism G30, the movable member G50 can be driven to move in a direction away from the inside of the photosensitive drum 20 together with the power receiving unit G21.
As shown in fig. 36 and 37, when the process cartridge is not mounted in the electrophotographic apparatus, the power receiving unit G21 is located in the frame G11, and the power receiving unit G21 and the movable member G50 are disposed close to the photosensitive drum 20 with the power receiving unit G21 at the initial position.
As shown in fig. 38 to 39, when the process cartridge 1 is mounted in the electrophotographic apparatus, the front end of the pressing member G40 abuts against the blocking wall 1081, and as the process cartridge 1 is further mounted, the pressing member G40 is inserted into the opening of the blocking wall 1081 to contact the driving unit 1080, and when the front end of the process cartridge 1 moves down and drives the pressing member G40 fixed relatively to the process cartridge to move down, the front end of the pressing member G40 presses down the driving unit 1080, causing the driving unit 1080 to move down to be substantially coaxial with the power receiving unit G21 to receive power. And in a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member G40 is completely misaligned with the projection of the photosensitive drum. Meanwhile, in the process that the pressing member G40 presses down the driving unit 1080, as the driving unit 1080 moves downward to be in contact with the driving gear G80, since the outer circumference of the driving unit 1080 is provided with an external gear portion (see fig. 1) having a helical tooth structure, the external gear portion of the driving unit 1080 is engaged with the driving gear G80, so that the driving gear G80 transmits the received driving force to the intermediate gear G32, and then the intermediate gear G32 transmits the driving force to the gear portion of the movable member G50 engaged therewith, thereby driving the movable member G50 to rotate, and as the movable member G50 rotates, the protrusion G52 moves to a position abutting against the inclined surface G62 and moves from a low position to a high position along the inclined surface G62, so that the movable member G50 and the power receiving unit G21 relatively fixedly connected with the movable member G50 move in a direction away from the photosensitive drum 20, thereby causing the power receiving unit G21 to protrude from the support G11, and at this time, the power receiving unit G21 is in a second position, and finally the power receiving unit G21 is successfully engaged with the driving unit 1080, thereby achieving the transmission of the driving force. Since the control mechanism G30 is not connected to the developing roller 30, the control mechanism G30 cannot transmit the driving force received from the driving unit 1080 to the developing roller 30. Therefore, a photosensitive drum gear G25 is further provided at an end of the photosensitive drum 20 away from the movable member G50, and a developing roller gear G26 is further provided at an end of the developing roller 30 away from the movable member G50, the developing roller gear G26 being engaged with the photosensitive drum gear G25, so that the movable member G50 can transmit the driving force received from the power receiving unit G21 to the photosensitive drum gear G25 and further to the developing roller gear G26 engaged with the photosensitive drum gear G25, thereby driving the developing roller 30 to rotate.
The method of removing the process cartridge from the electronic imaging device in this embodiment is similar to that in the sixth embodiment, and the user can remove the process cartridge from the electronic imaging device more smoothly by the relative inclination of the process cartridge during the removal process.
Referring to fig. 37, in some embodiments, a resilient return member G27 is provided at an end of the power receiving unit G21 remote from the engagement portion G211, and the resilient return member G27 may be a compression spring. When the driving unit 1080 stops rotating, since the elastic force of the elastic restoring member G27 is greater than the acting force of the driving unit 1080 and the power receiving unit G21, the power receiving unit G21 can be pulled back to the initial position by the elastic restoring member G27. The arrangement of the structure can smoothly take out the processing box without inclining the processing box.

The first movable member H1033 is retracted, i.e., deflected, closer to the second side wall H102 with respect to the first position at the second position, in which the process cartridge 1 can be mounted in place so that the process cartridge can receive the driving force from the electronic image forming apparatus and perform a normal print job. The term "mounted in place" as used herein means that the process cartridge 1 can normally receive a driving force to perform a print job after being mounted. In this embodiment, the first movable component H1033 is a bump.
The second recognition mechanism is provided on a first side wall H101 of the electronic image forming apparatus, and is configured as a swing lever H1013 capable of swinging about a rotation axis parallel to the longitudinal direction Y of the process cartridge 1, and a pushed portion H1014 protruding in the longitudinal direction Y of the process cartridge is provided on an upper side of the swing lever H1013. In the installation direction of the process cartridge 1, the free end of the swinging rod H1013 is located at the downstream side, and the end hinged to the rotating shaft is located at the upstream side, that is, the swinging rod is in an inclined state as a whole, and the swinging rod H1013 can extend to the third guide rail H1012, so that the process cartridge 1 needs to push the swinging rod H1013 to rotate in the installation process to realize smooth installation of the process cartridge 1, otherwise, the process cartridge cannot be installed.
As shown in fig. 43 to 45, the process cartridge 1 of the present embodiment further includes a first guided portion H41 and a second guided portion H42, the first guided portion H41 and the second guided portion H42 being provided at a first end 1A (an end provided with a power receiving unit) of the process cartridge 1, specifically, the first guided portion H41 being provided on the photosensitive drum frame and being located on the upstream side of the photosensitive drum 20 in the mounting direction of the process cartridge.

The second guided portion H42 can be abutted against the second guide rail H104 at a later stage in the process of mounting the process cartridge 1, and the second guided portion H42 of the present embodiment is located above the first guided portion H41 in the mounted state of the process cartridge 1, is located on the downstream side of the first guided portion H41 in the mounting direction of the process cartridge, and is fixedly connected to the pressing member H40. Preferably, the second guided portion H42 is integrally formed with the pressing member H40, and the second guided portion H42 is located on the upper side of the pressing member H40 in the mounting direction of the process cartridge 1. Preferably, the second guided portion H42 is located on the upper side of the outer periphery of the photosensitive drum 20.

The first guide surface H44 is located on the upper side of the process cartridge 1 as a whole. The first guide surface H44 is located on the upstream side of the photosensitive drum 20 and on the upstream side of the abutting portion where the pressing member H40 and the driving unit 1080 abut each other in the mounting direction of the process cartridge 1. In the present embodiment, the first guide surface H44 is disposed to face upward and upward, and may be provided as a curved surface. In a state where the process cartridge 1 is mounted to the electronic image forming apparatus, the first guide surface H44 can be pressed by the first movable member H1033 to restrict the rotation of the process cartridge 1, and play a role in positioning the process cartridge 1, in which case the first guide surface H44 may be provided in a non-inclined surface structure. The first guide surface H44 having an inclined structure can avoid interference with the first movable member H1033 during the mounting and removal of the process cartridge 1, and avoid affecting the mounting and removal operation of the process cartridge 1, as compared with the non-inclined structure.

In the range, the matching effect of the swing rod and the swing rod is better.
Next, the specific operation of the process cartridge 1 to be mounted to the electronic image forming apparatus and the fitting process of the respective components will be described in detail with reference to fig. 42 to 49.
In the process cartridge mounting process, a stage before the second guided portion H42 is not supported by the second guide rail H104 is referred to as a front stage (or front mounting section) in the process cartridge 1 mounting process, and a stage after the second guided portion H42 is supported by the second guide rail H104 is referred to as a rear stage (or rear mounting section) in the process cartridge 1 mounting process.
In the early stage of the process cartridge mounting, a user holds a handle (not shown in the drawings) of the process cartridge 1 to set the process cartridge in the electronic image forming apparatus, and causes the first guided portion H41 and the third guided portion H43 to be respectively fitted into the first guide rail H103 and the third guide rail H1012 and push the process cartridge 1 in the mounting direction of the process cartridge 1, at which time the first guided portion H41 of the process cartridge 1 may abut on the first guide section H1031 of the first guide rail H103, and the third guided portion H43 abuts on the third guide rail H1012, that is, the process cartridge is supported by the first guide section H1031 and the third guide rail H1012 of the first guide rail H103. As the process cartridge 1 moves forward along the guide rail in the direction X of the mounting direction of the process cartridge (as shown in fig. 41 b), when the first guided portion H41 moves to the end of the first guide section H1031 of the first guide rail H103 or moves to the second guide section H1032 (i.e., reaches the recessed position), the second guided portion H42 abuts on the third guide section H1041 of the second guide rail H104, and the first guided portion H41 also comes out of abutment with the first guide rail H103, and the first end 1A of the process cartridge is lifted.
At the later stage of the process cartridge mounting, the second guided portion H42 abuts on the third guide section H1041, the third guided portion H43 abuts on the third guide rail H1012, and the process cartridge is supported by the second guide rail H104 and the third guide rail H1012. As the process cartridge 1 continues to advance toward the mounting direction X of the process cartridge, the second guided portion H42 enters the fourth guide section H1042 against the third guide section H1041; during the movement of the second guided portion H42 against the fourth guide section H1042, the process cartridge 1 rotates in the W direction with the contact point between the second guided portion H42 and the fourth guide section H1042 and the contact point between the third guided portion H43 and the third guide rail H1012 as the fulcrum, that is, the process cartridge 1 advances in a manner of moving along the guide rail while rotating, and the pressing member H40 is lifted in the W direction, so that the interference between the pressing member H40 and the blocking wall 1081 can be avoided; in this process, the process cartridge may advance under the action of external force or may advance under the action of its own weight.
As the process cartridge 1 continues to advance in the process cartridge mounting direction (X direction), the second guided portion H42 finally disengages from the second guide rail H104 from the fifth guide section H1043, the urging member H40 extends into the opening 10813 above the blocking wall 1081 to urge the driving unit 1080, and the guide urging surface H45 is urged against the outer edge 10814 of the opening 10813, and the process cartridge 1 is mounted. The first movable member H1033 is pressed against the first guide surface H44 to restrain the process cartridge 1 from rotating, so that the process cartridge 1 is more stable. In this process, the process cartridge may advance under the action of external force or may advance under the action of its own weight.
Referring to fig. 43 to 45, in the process of mounting the process cartridge 1, the first end 1A of the process cartridge 1 is provided with the avoiding portion H48 having a hollowed-out structure, so that the process cartridge 1 can avoid interference with the first movable member H1033 in the process of mounting. During the process of mounting the process cartridge 1, the first pressing surface H46 provided at the second end 1B of the process cartridge 1 first contacts the pushed portion H1014 on the upper side of the swinging rod H1013 and pushes the swinging rod H1013 to rotate, thereby preventing the third guided portion H43 from being blocked by the free end of the swinging rod H1013.
When the process cartridge 1 is detached, the user holds the handle of the process cartridge 1, and takes out the process cartridge 1 from the electronic imaging device in the direction opposite to the process cartridge mounting direction X. In the early stage of the detachment of the process cartridge 1, the second guided portion H42 abuts against the second rail H104 and moves along the second rail H104, and in the later stage of the detachment, the second guided portion H42 is supported by the first guided portion H41 of the process cartridge 1, that is, the second guided portion H42 abuts against the first rail H103 and moves along the first rail H103, and the third guided portion H43 is always supported by the third rail H1012.
With reference to fig. 49 to 50, in the process of disassembling the process cartridge, particularly when a user just starts to pull the process cartridge, since the first guide surface H44 is pressed by the first movable member H1033, the process of rotating the process cartridge 1 in the opposite direction of the W direction is suppressed, thereby reducing the depth of the pressing member H40 embedded into the opening 10813, and further reducing or avoiding interference between the pressing member H40 and the blocking wall 1081 when taking out, and further, since the pressing member H40 is provided with the guide pressing surface H45, the process cartridge 1 is disassembled more smoothly.
When the second guided portion H42 abuts against the fourth guide section H1042, the pressing member H40 has retracted from the opening 10813, the process cartridge can rotate in the reverse direction of the W direction to a preset angle under the action of an external force, and the second pressing surface H47 of the process cartridge 1 first contacts the pushed portion H1014 of the swinging rod H1013 and pushes the swinging rod H1013 to rotate, thereby preventing the third guided portion H43 from being blocked by the free end of the swinging rod H1013 during the process of removing the process cartridge 1 from the electronic imaging device.
Example nine
The process cartridge and the electronic imaging device of the present embodiment are substantially identical in shape and structure to those of the process cartridge and the electronic imaging device of the eighth embodiment, and the description of the eighth embodiment is omitted, so that only the differences in the eighth embodiment are described below.
As shown in fig. 52a, in the example of the electronic imaging device of the present embodiment, the second side wall I102 of the main assembly I100 of the electronic imaging device is provided with a fourth guide rail I105, and preferably, the fourth guide rail I105 is at least partially located on the lower side of the second guide rail I104 and is closer to the first side wall I101 of the main assembly I100 along the Y direction with respect to the second guide rail I104. The fourth rail I105 is at least partially located on the upstream side of the second rail I104 in the mounting direction of the process cartridge. In the present embodiment, the fourth guide rail I105 is inclined to the rear side of the main assembly I100, and the fourth guide rail I105 may be configured as an inclined surface, or may be a curved surface or a guide groove.
As shown in fig. 52b, a third guide rail I1012 is provided on the first side wall I101 to guide the mounting and positioning of the process cartridge 1, and in this embodiment, the third guide rail I1012 is composed of an inclined surface; alternatively, the third guide rail I1012 may be formed of a curved surface or a guide groove. Preferably, the third guide rail I1012 includes a sixth guide section I1015 and a seventh guide section I1016, and the seventh guide section I1016 is located on the downstream side of the sixth guide section I1015 in the mounting direction (X direction, as shown in fig. 41 b) of the process cartridge 1. Preferably, the seventh guide section I1016 is parallel to the bottom surface of the main assembly I100, and the sixth guide section I1015 is connected to the seventh guide section I1016 and is inclined toward the rear side of the main assembly I100.
As shown in fig. 53, the process cartridge in this embodiment is not provided with the first guided portion relative to the eighth embodiment, and further includes a fourth guided portion I41, the fourth guided portion I41 being provided on the lower side of the process cartridge 1 (downstream of the process cartridge 1 in a state in which the process cartridge 1 is mounted to the electronic image forming apparatus) and at the first end 1A of the process cartridge. Preferably, the fourth guided portion I41 is provided on the end cap I102b of the developing frame I101 b. Preferably, the fourth guided portion I41 is configured as an arc surface, and the fourth guided portion I41 is located on the lower side of the second guided portion I42 in a state where the process cartridge 1 is mounted to the electronic image forming apparatus. The fourth guided portion I41 is located on the upstream side of the second guided portion I42 in the mounting direction of the process cartridge 1. Alternatively, the fourth guided portion I41 may be provided at other positions of the end of the developing frame I101b or configured as a member extending from other positions of the process cartridge as long as it can be engaged with the fourth guide rail I105 during the mounting process.
As in the eighth embodiment, the second end 1B of the process cartridge 1 of the present embodiment is also provided with a first pressing surface I46 for unlocking the swing lever I1013 (second identifying means) during the mounting process and a second pressing surface I47 for unlocking the swing lever I1013 during the dismounting process of the process cartridge 1 from the electronic image forming apparatus, the first pressing surface I46 and the second pressing surface I47 being higher than the upper surface of the process cartridge. During the mounting and dismounting of the process cartridge, the second pressing surface I47 and the first pressing surface H46 are both stepped, i.e., have a height difference, and the second pressing surface H47 is located on the upper side of the first pressing surface H46. In the present embodiment, the first pressing surface I46 and the second pressing surface I47 are configured as curved surfaces or inclined surfaces. Specifically, the first pressing surface I46 and the second pressing surface I47 are inclined toward the opposite direction of the process cartridge mounting direction (X direction).
In some possible embodiments, in the present embodiment, the process cartridge 1 further includes a restricting portion I471, the restricting portion I471 being capable of restricting the position of the process cartridge 1 when the process cartridge is detached, so as to avoid unsmooth detachment of the process cartridge 1 due to excessive rotation of the process cartridge. For example, in some embodiments, the process cartridge may rotate integrally during the process of taking out, and the process cartridge 1 rotating beyond a certain range may affect the effect of taking out the cartridge, so that it is necessary to limit the movement of the process cartridge 1 during the process of taking out, so that the process cartridge is prevented from rotating too much. Preferably, the restricting portion I471 is provided on the second pressing surface I47, and the restricting portion I471 is restricted by the swinging lever I1013 when the process cartridge rotates, thereby restricting the process cartridge from rotating.
Next, a detailed description will be given of a specific operation procedure of detaching or attaching the process cartridge 1 from or to the electronic imaging device and a procedure of fitting each component to the electronic imaging device with reference to fig. 52a to 59 b.
In the process cartridge 1 mounting process, a stage before the second guided portion I42 is not supported by the second guide rail I104 is referred to as a front stage (or front mounting section) in the process cartridge 1 mounting process, and a stage after the second guided portion I42 is supported by the second guide rail I104 is referred to as a rear stage (or rear mounting section) in the process cartridge 1 mounting process.
In the early stage of the mounting of the process cartridge 1, referring to fig. 55, the user holds the handle (not shown) of the process cartridge 1, places the process cartridge in the electronic image forming apparatus, and causes the fourth guided portion I41 and the third guided portion I43 to be fitted into the positions of the fourth guide rail I105 and the third guide rail I1012, respectively, and pushes the process cartridge 1 in the mounting direction (X direction) of the process cartridge 1, at which time the fourth guided portion I41 of the process cartridge 1 may abut on the surface of the fourth guide rail I105, the second guided portion I42 may not abut on the second guide rail I104, and the third guided portion I43 may abut on the surface of the sixth guide section I1015 of the third guide rail I1012, that is, the process cartridge 1 can be supported by the fourth guide rail I105 and the third guide rail I1012 without being supported by the second guide rail I104. During this time, in some possible embodiments, unlocking the swing lever I1013 is also included to enable accurate mounting of the process cartridge; that is, the first pressing surface I46 first contacts the swinging rod I1013 and presses the swinging rod I1013 to swing from the locking position to the unlocking position, so as to avoid the installation interference caused by the contact of the third guided portion I43 and the swinging rod I1013.
As the process cartridge 1 continues to move forward along the guide rail in the cartridge mounting direction X, as shown in fig. 56, the second guided portion I42 abuts against the second guide rail I104, and the fourth guided portion I41 is out of abutment with the fourth guide rail I105. The process cartridge 1 enters the post-mounting stage, the second guided portion I42 abuts on the third guide section I1041, the third guided portion I43 abuts on the surface of the third guide rail I1012 (specifically, may abut on the surface of the sixth guide section I1015), and the process cartridge 1 is supported by the second guide rail I104 and the third guide rail I1012. As the process cartridge 1 advances, the second guided portion I42 may enter the fourth guide section I1042 against the third guide section I1041. Preferably, during the movement of the second guided portion I42 against the fourth guide section I1042, the process cartridge 1 may rotate in the W direction with the contact point between the second guided portion I42 and the fourth guide section I1042 and the contact point between the third guided portion I43 and the third guide rail I1012 as the pivot point, that is, the process cartridge 1 advances in a manner of moving along the guide rail while rotating, and the pressing member I40 is lifted in the W direction, which movement can avoid the interference of the pressing member I40 with the blocking wall 1081 in the advancing direction; in this process, the process cartridge 1 may be advanced by external force or advanced and rotated by its own weight.
Referring to fig. 41b, in some possible embodiments, as the process cartridge 1 continues to advance toward the cartridge mounting direction X, the second guided portion I42 finally disengages from the second guide rail I104 at the fifth guide section I1043, the pressing member I40 protrudes into the opening 10813 (shown in fig. 41 b) above the blocking wall 1081 to press the driving unit 1080, and the second guide surface I45 presses against the outer edge 10814 (shown in fig. 41 b) of the opening 10813, so that the process cartridge 1 is completely mounted. The first movable member I1033 is pressed against the first guide surface I44 to restrain the process cartridge 1 from rotating, so that the process cartridge 1 is more stable. In this process, the process cartridge 1 may be advanced by external force or by gravity itself.
In some possible embodiments, the second guided portion I42 of the process cartridge may rotate in the W direction when abutting the third guide section I1041 or the fifth guide section I1043, so as to avoid interference and ensure smooth installation of the process cartridge.
In some possible embodiments, the mounting process of the process cartridge 1 further includes a mounting end stage, in which the mounting process after the second guided portion I42 of the process cartridge 1 is separated from the second guide rail I104 is referred to as a mounting end stage (or a non-mounting section), and in this embodiment, as shown with reference to fig. 57, the second guided portion I42 is separated from the second guide rail I104, the free end portion of the pressing member I40 is pressed against the upper side of the blocking wall 1081, and the first end 1A of the process cartridge 1 is lifted by a preset distance (as shown in fig. 58); as the process cartridge 1 moves forward, the pressing member I40 presses the driving unit 1080 in the opening 10813 above the blocking wall 1081, and the first end 1A of the process cartridge also sinks downward as a whole, and can force the driving unit 1080 to rotate to a position overlapping the blocking wall 1081 axis when the door of the image forming apparatus is closed, at which time the power receiving unit provided on the process cartridge 1 engages with the driving unit 1080. And on a plane perpendicular to the axial direction of the photosensitive drum, the projection of the pressing member is located outside the projection range of the photosensitive drum.
The process of fitting the components of the process cartridge is referred to the process of fitting the components of the process cartridge to the process of mounting the process cartridge, and the design of this structure can make the process cartridge more smooth to be removed and mounted.
Specifically, when the process cartridge 1 is detached, the user holds the handle of the process cartridge 1, takes the process cartridge 1 out of the electronic imaging device in the opposite direction to the process cartridge mounting direction X, and in the early stage of detachment of the process cartridge 1, lifts the rear portion of the process cartridge to rotate the process cartridge by a preset angle when the process cartridge is initially pulled to reduce interference; as the process cartridge moves, the second guided portion I42 abuts on the second guide rail I104 and moves along the second guide rail I104. In some possible embodiments, the second pressing surface I47 first contacts the pushed portion I1014 of the swinging rod I1013 and pushes the swinging rod I1013 to swing from the locking position to the unlocking position, so as to avoid the third guided portion I43 contacting the swinging rod I1013 and avoiding the box taking interference.
In the later stage of the disassembly, the fourth guided portion I41 of the process cartridge 1 is supported, that is, the fourth guided portion I41 abuts on the fourth rail I105 and moves along the fourth rail I105, while the third guided portion I43 is always supported by the third rail I1012.
In some possible embodiments, the process cartridge may rotate during the process of removing the process cartridge, which may be caused by, for example, a direction of pulling force of a user or a special structural design of the process cartridge. As shown in fig. 59a and 59b, during the movement of the third guided portion I43 from the seventh guide section I1016 of the third guide rail I1012 to the junction with the sixth guide section I1015, the second pressing surface I47 contacts the swing lever I1013 and pushes the swing lever I1013 to swing upward to unlock the swing lever I1013.
As the process cartridge moves in the opposite direction to the process cartridge mounting direction (X direction), the process cartridge may rotate a preset angle in the W2 direction, the restricting portion I471 abuts against the pushed portion I1014 of the rocking lever I1013, the rocking lever I1013 swings upward to an upper limit position (e.g., in some embodiments, the rocking lever I1013 abuts against a side wall or other restricting member of the electronic image forming apparatus at the upper limit position and thus cannot swing only), and the process cartridge cannot continue to rotate due to the abutting of the restricting portion I471 against the pushed portion I1014 of the rocking lever I1013, thereby enabling the process cartridge to be removed more smoothly. In some embodiments, the limiting portion I471 is configured to prevent the process cartridge from rotating excessively at the predetermined position, and thus prevent the pressing member I40 from interfering with the blocking wall or the side wall of the electronic imaging device.
In some possible embodiments, the limiting portion I471 abuts against the pushed portion I1014 of the swinging rod I1013 and brings the swinging rod I1013 to the upper limit position, that is, when the third guided portion I43 is located in the sixth guiding section I1015, or when the third guided portion I43 is located at the intersection of the sixth guiding section I1015 and the seventh guiding section I1016, it is of course also possible that the third guided portion I43 is located in the seventh guiding section I1016.
In some possible embodiments, there may be a case where the fourth guided portion I41 is supported by the fourth guide rail I105 and the second guided portion I42 is supported by the second guide rail I104 at the same time during the mounting or dismounting of the process cartridge 1, for example, during the transition in the early and late stages of the mounting.
In some possible embodiments, there may be a case where the second guided portion I42 is supported by the second guide rail I104 and the pressing member I40 is supported by the blocking wall 1081 during the mounting or dismounting of the process cartridge 1, for example, during the transition between the late stage of mounting and the late stage of mounting.
In some possible embodiments, since the fourth guided portion I41 of the process cartridge abuts on the surface of the fourth guide rail I105 in the early stage of the process cartridge mounting, the third guided portion I43 abuts on the surface of the sixth guide section I1015 of the third guide rail I1012, that is, the process cartridge is supported by two fulcrums, whereby the process cartridge can be deflected about the two fulcrums during the mounting, so that interference with part of the structure in the electronic imaging device can be avoided, and the mounting of the process cartridge is smoother.
Examples ten
The present embodiment is an improvement made on the basis of the eighth embodiment and the ninth embodiment, and the same points are not described in detail, and the main differences are mainly described below.
Referring to fig. 52a and 52b, the main assembly of the electronic imaging device further includes a fifth guide K1017. In this embodiment, the fifth guide K1017 is located between the first sidewall I101 and the second sidewall I102 of the main assembly I100 of the electronic imaging device and is configured as a slope, alternatively, may be a curved surface or a guide groove.
In addition to the process cartridges provided in the eighth and ninth embodiments, the process cartridge in this embodiment further includes a fifth guided portion K41 that cooperates with the fifth rail K1017 while eliminating the first guided portion. As shown in fig. 60, a fifth guided portion K41 is provided on the lower side of the process cartridge, specifically on the lower side of the developing frame 101b, so as to be supported by the fifth guide rail K1017 during mounting or dismounting of the process cartridge. Preferably, the fifth guided portion K41 is provided at a position in the middle of the process cartridge biased toward the second end 1B. Alternatively, the fifth guided portion K41 may be provided in the middle or first end portion 1A as long as it can be engaged with the fifth rail K1017. The process cartridge of this embodiment is basically the same as that of the eighth and ninth embodiments in the mounting or dismounting process, and is mainly different in that the process cartridge 1 of this embodiment is supported by the fifth rail K1017 at the early stage of mounting, that is, in such a manner that the fifth guided portion K41 is engaged with the fifth rail K1017.
In some possible embodiments, referring to fig. 60, the process cartridge may simultaneously retain the fourth guided portion I41 and the fifth guided portion K41, and the process cartridge is supported by the fourth rail I105 and the fifth rail K1017 at the front or rear of the mounting/dismounting of the process cartridge, that is, the fourth guided portion I41 can abut the fourth rail I105 and the fifth guided portion K41 can abut the fifth rail K1017 at the front or rear of the mounting/dismounting of the process cartridge.
Example eleven
The present embodiment is an improvement made on the basis of the foregoing embodiment, and the same points are not repeated, and the main differences are mainly described below.
In the present embodiment, the unlocking member L47 is provided so as to be movable with respect to the cartridge body, thereby increasing the flexibility of the process cartridge at the time of mounting and/or dismounting from the electronic image forming apparatus, and reducing the possibility of the process cartridge interfering during mounting and dismounting.
Specifically, as shown in fig. 61, in the present embodiment, the process cartridge further includes an elastic member L47b, the elastic member L47b is provided between the photosensitive drum frame 12 and the unlocking member L47, and a preset movable space is provided between the unlocking member L47 and the photosensitive drum frame 12, the unlocking member L47 being movable in the L direction and the opposite direction of L. Preferably, the elastic member L47b may be a compression spring, an extension spring or an elastic arm integrally formed with the unlocking member. When the first pressing surface L46 or the second pressing surface L47a of the unlocking member L47 touches the swing lever I1013 to unlock, the unlocking member L47 can move against the elastic force of the elastic member L47 b.
In some possible embodiments, the unlocking member L47 may remain in contact with the swing lever I1013 after touching and unlocking the swing lever I1013 (as shown in fig. 59 c) during the process of mounting or dismounting the process cartridge to or from the electronic image forming apparatus, that is, the unlocking member L47 may still abut the swing lever I1013 in a state in which the process cartridge is mounted in place.
In some possible embodiments, the unlocking member L47 still abuts the swing lever I1013 in a state where the process cartridge is mounted in place, and brings the swing lever I1013 into an unlocking position.
Example twelve
This embodiment is a further improvement made on the basis of the foregoing embodiment, and the same parts are not described in detail, and the improvements will be mainly described below.
As shown in fig. 62, the process cartridge includes a photosensitive drum 20 and a charging roller M20a, the photosensitive drum 20 and the charging roller M20a being rotatably supported on a photosensitive drum frame. Fig. 62 shows a projection of the process cartridge on a plane perpendicular to the rotational axis of the photosensitive drum, on the projection plane, taking the rotational center of the photosensitive drum as Q1, the rotational center of the charging roller M20a as Q2, taking a straight line passing between Q1 and Q2 as a1, and taking a straight line passing through Q1 and perpendicular to the straight line a1 as a2; the vertical distance from the point on the first pressing surface M46 to the straight line a1 is S1, the vertical distance from the point on the second pressing surface M47 to the straight line a1 is S2, the horizontal distance from the point on the first pressing surface M46 to the straight line a2 is S3, and the horizontal distance from the point on the second pressing surface M47 to the straight line a2 is S4. Generally, too large or too small of S1, S2, S3, and S4 affect the mounting and dismounting of the process cartridge and the fitting with the swing lever I1013.
In order to make the mounting of the process cartridge smoother, and the first pressing surface M46 and the second pressing surface M47 are better matched with the swing lever I1013, it is preferable that 20 mm.ltoreq.S1.ltoreq.35 mm,20 mm.ltoreq.S2.ltoreq.40 mm,5 mm.ltoreq.S3.ltoreq.35 mm,40 mm.ltoreq.S4.ltoreq.80 mm.
Further, the technical scheme is further optimized. If the values of S1 and S3 are respectively: s1 is more than or equal to 25mm and less than or equal to 27mm, S3 is more than or equal to 18mm and less than or equal to 32mm, S1 and S3 meeting the value requirement can ensure that the treatment box is smoother in installation, and the matching effect of the first pressing surface M46 and the swinging rod I1013 is better.
For illustration, fig. 63 shows a combination of S1 minimum and S3 minimum, and this structural design makes the process cartridge smoother when being installed, and the matching effect of the first pressing surface M46 and the swinging rod I1013 is better.
When the minimum value of S2 is less than or equal to 29mm and less than or equal to 37.5mm, and the minimum value of S4 is less than or equal to 52mm and less than or equal to 80mm, the processing box is smoother when being taken out from the electronic imaging device, and the matching effect of the second pressing surface M47 and the swinging rod I1013 is better.
For illustration, fig. 64 shows a combination of the minimum value of S2 and the minimum value of S4, and this structural design makes the process cartridge smoother when being mounted, and the cooperation effect of the first pressing surface 47 and the swinging rod I1013 is better.
This embodiment is a further improvement made on the basis of the foregoing embodiment, and the same parts are not described in detail, and the improvements will be mainly described below.
As shown in fig. 65, the process cartridge includes the photosensitive drum 20 and the charging roller M20a, and fig. 65 shows a projection of the process cartridge on a plane perpendicular to the rotational axis of the photosensitive drum, on the projection plane, the rotational center of the photosensitive drum 20 is taken as Q1, the rotational center of the charging roller M20a is taken as Q2, a straight line passing between Q1 and Q2 is taken as a1, and a straight line passing through Q1 and perpendicular to the straight line a1 is taken as a2. The perpendicular distance from the free end of the pressing member M40 to the straight line a1 is S5, and the perpendicular distance from the free end of the pressing member M40 to the straight line a2 is S6.
In order to make the loading and unloading smoother and to avoid interference of the pressing member with the blocking wall 1081. Too small/too large S5 and/or too large/too small S6 make the loading/unloading of the cartridge unsmooth, and the fit with the driving unit 1080 is also poor. For example, in some embodiments, too large S5 and/or too small S6 may be present to effectively urge the drive unit 1080, i.e., to better urge the drive unit 1080 to align. In some embodiments, too small of S5 and/or too large of S6 may cause interference with the printer when loading or unloading the cartridge.
Through research and installation test, preferably, when S5 which is more than or equal to 8mm and less than or equal to 15mm, S6 which is more than or equal to 4mm and less than or equal to 12mm, the processing box is smooth when being installed to or detached from the electronic imaging device, and can effectively press the driving unit 1080.
For example, when the selected values of S5 and S6 are combined as shown in fig. 66, the process cartridge is smoother in the loading process, and the cooperation effect of the pressing member M40 and the driving unit 1080 is better.
Example thirteen

When the driving unit 1080 is in the unlocked state, the driving unit 1080 can be moved by an external force, that is, the driving unit 1080 can be changed from the tilted position to the aligned position (i.e., a state in which it is not tilted) by an external force and can protrude from the second side wall N107, so that the driving force can be stably transmitted to the process cartridge 1.
As shown in fig. 70 to 72, the process cartridge 1 includes a cartridge body N10, a photosensitive drum 20, a developing roller 30, and a power receiving unit N21, and in this embodiment, the cartridge body N10 includes a drum frame 12 for supporting the photosensitive drum 20 and a developing frame 11 for supporting the developing roller 30, the drum frame 12 and the developing frame 11 being rotatably connected to each other during operation, and being capable of moving together in synchronization during installation of the process cartridge 1.

The power receiving unit N21 is provided at the first end N50 of the cartridge body N10, and the power receiving unit N21 includes a power receiving portion N211, the power receiving portion N211 being capable of engaging with the drive transmitting portion N1082 of the driving unit 1080 to receive the driving force, thereby being capable of driving the developing roller 30 and the photosensitive drum 20 to rotate.
Further, in order to convert the driving unit 1080 from the tilted state of the initial position (in which the rotation axis NL1 of the driving unit 1080 is tilted with respect to the rotation axis NL2 of the photosensitive drum 20) to the aligned state in which the rotation axis of the driving unit 1080 coincides with the rotation axis of the photosensitive drum 20, which is capable of meshing with the power receiving unit N21, as shown in fig. 70 to 73, the process cartridge 1 further includes a pressing member N40 provided at the first end N50 for applying a force to the driving unit 1080 so that the driving unit 1080 is at the aligned position, and a distance between the pressing member N40 and the photosensitive drum axis does not undergo a displacement change during the process of mounting the process cartridge 1 to the electronic imaging device. Specifically, the urging member N40 is fixedly mounted on the end cap N202 so as to form a fixed connection with the drum frame 12.
As shown in fig. 70 to 74, the pressing member N40 includes mounting bosses N401, and in the present embodiment, two mounting bosses N401 are provided, one of the mounting bosses N401 being located on the upper side of the other mounting boss N401.

The pressing member N40 is located outside the end portion of the power receiving portion N211 in the rotation axis direction NL2 of the photosensitive drum 20 so as to be capable of cooperating with the driving unit 1080 when the process cartridge is mounted. Further, the urging member N40 includes a cantilever N402 for urging the driving unit 1080, the cantilever N402 being located on the front side of the urging member N40, and on a plane perpendicular to the rotational axis of the photosensitive drum 20, the projection of the cantilever N402 at least partially coincides with the projection of the photosensitive drum 20. That is, at least a portion of the urging member N40 is located within the projection section of the photosensitive drum 20. Alternatively, in other embodiments, the end cap may be omitted, and the pressing member N40 may be disposed directly on the drum frame 12, as long as the distance between the pressing member N40 and the rotation axis of the photosensitive drum 20 in the radial direction of the photosensitive drum 20 is unchanged. Alternatively, the position of the pressing member N40 may be set outside the circumferential outer surface of the photosensitive drum 20 or inside the photosensitive drum 20 in the radial direction of the photosensitive drum 20, as long as it can cooperate with the driving unit 1080.
Further, the process cartridge 1 further includes a guide projection N704 and a guided portion N70 movable relative to the drum frame 12, the guided portion N70 being provided on the end cap N202 of the first end N50, and the guided portion N70 being engaged with the guide rail N108 located on the second side wall N107. In the present embodiment, the guided portion N70 includes a first projection N701 protruding from the end surface of the end cover N202, and the first projection N701 can be inserted into the guide rail N108 on the second side wall N107 of the housing portion N105 when the process cartridge 1 is mounted to the housing portion N105, so that the mounting of the process cartridge 1 can be guided. The guide projection N704 is provided at an end of the cartridge body N10 remote from the guided portion N70, and the guide projection N704 is engaged with the guide rail N108 of the first sidewall N106 to be able to guide the mounting of the process cartridge 1. In the present embodiment, the guide projection N704 is fixedly connected to the drum frame 12, and is capable of moving in synchronization with the drum frame 12.
As shown in fig. 73, a groove N80 is provided on the end face of the end cover N202, the groove N80 being provided with guide grooves N801 on the front and rear side walls, respectively, which are provided opposite to each other along the mounting direction NY1 of the process cartridge 1, the guide grooves N801 extending in the first direction. Correspondingly, the guided portion N70 includes a second projection N702 that mates with the guide groove N801, and the second projection N702 is embedded in the guide groove N801 such that the guided portion N70 can move in the first direction with respect to the drum frame 12, that is, the drum frame 12 of the process cartridge 1 or the entire cartridge N10 can move in the first direction with respect to the guided portion N70. In other embodiments, the guided portion N70 may be provided with a guide groove N801, and the drum frame 12 may be provided with a second projection N702 that engages with the guide groove N801. Alternatively, the guided portion N70 may be provided fixedly connected to the developing frame 11. The first direction is a direction intersecting the rotation axis NL2 of the photosensitive drum 20 and the mounting direction NY1 of the process cartridge 1.
In order to facilitate the fitting action between the guided portion N70 and the guide rail N108 or to facilitate the mounting of the process cartridge 1, the guided portion N70 further includes an elastic member. In this embodiment, the elastic member is a compression spring N90, and the compression spring N90 has two.

Alternatively, the elastic member may be omitted or only one elastic member may be used, and the first projection N701 may be made movable with respect to the drum frame 12 or the developing frame 11, or movable with respect to the entire process cartridge 1. Alternatively, a plurality of guided portions N70 may be provided, or the same guided portion N70 may be provided at the other end of the process cartridge 1, so that both ends of the process cartridge can move relative to the guide rail N108.
The following describes the mounting process of the process cartridge 1 with reference to fig. 67 to 69, 75, and 76.
When the process cartridge 1 is mounted in the electrophotographic image forming apparatus 100 in the NY1 direction, the first projection N701 is fitted into the guide rail N108 of the second side wall N107 of the accommodating portion N105, and the guide projection N704 on the other side of the process cartridge 1 is fitted into the guide rail N108 of the first side wall 106, so that the process cartridge 1 is guided and mounted in the NY1 direction, in which state the first end N50 of the process cartridge 1 is movable with respect to the guided portion N70 in a direction intersecting the mounting direction NY1 and the photosensitive drum axis NL 2. As the process cartridge 1 moves, the pressing member N40 fixed to the drum frame 12 gradually approaches the driving unit 1080 as the process cartridge 1 moves, and when the pressing member N40 contacts the circumferential outer surface of the small diameter cylindrical body N1083 of the driving unit 1080, the driving unit 1080 is in a locked state because the door cover 102 is not closed, the pressing member N40 presses the circumferential outer surface of the small diameter cylindrical body N1083, the first end N50 of the developing cartridge 1 is lifted by a predetermined distance, and the cartridge body N10 (including the drum frame 12 and the developing frame 11) is displaced with respect to the first projection N701, thereby enabling smooth installation of the process cartridge, avoiding failure of installation due to interference of the pressing member N40 with the driving unit 1080 or interference of other components. As shown in fig. 75, the pressing member N40 is finally pressed against the circumferential outer surface of the small-diameter cylindrical body N1083 of the driving unit 1080, at which time the driving unit 1080 is in an inclined state, the drive transmitting portion N1082 is in a retracted state with respect to the second side wall N107 of the housing portion N105, and the rotation axis NL1 of the driving unit 1080 and the rotation axis NL2 of the photosensitive drum 20 are in a crossing state.
When the door 102 is closed, the cam N104 releases the lock on the driving unit 1080, and since the cantilever N402 of the pressing member N40 presses on the driving unit 1080, the pressing member N40 applies a pressing force to the driving unit 1080, and the driving unit 1080 receives the pressing force to move in a direction approaching the power receiving unit 21 until the rotation axis NL1 of the driving unit 1080 coincides with the rotation axis NL2 of the photosensitive drum 20, in which state, when the electronic imaging device 100 is started, the power receiving unit 21 of the process cartridge 1 and the driving unit 1080 can be engaged and stably receive the driving force to rotate.
In the present embodiment, since the pressing member N40 is fixedly provided on the drum frame 12, its position with respect to the axis NL2 of the photosensitive drum 20 is always kept unchanged, that is, the distance of the pressing member N40 with respect to the axis NL2 of the photosensitive drum 20 is not changed in displacement. The force applied to the driving unit 1080 by the pressing member N40 to align the driving unit 1080 may be the gravity of the process cartridge 1 itself or the force applied to the process cartridge 1 by the door 102 when the door 102 is closed. Alternatively, the urging member N40 may be other portions of the urging drive unit 1080 as long as it can be urged to be aligned. Alternatively, the guided portion N70 may be another position provided on the cartridge body N10 as long as it can move relative to the cartridge body N10 and avoid interference of the process cartridge 1 with the electronic image forming apparatus when the process cartridge is mounted. Alternatively, with the electronic image forming apparatus in which the driving unit 1080 is not locked, since the pressing member N40 does not cause the process cartridge to be lifted when it is in contact with the driving unit 1080, the guided portion N70 may be eliminated in this case. Alternatively, the pressing member N40 may be other positions of the pressing driving unit 1080 as long as it can be aligned.
According to the embodiment, the pressing piece is arranged on the processing box, so that the contact and engagement process of the power receiving unit and the driving unit is smoother, the contact and engagement time of the power receiving part and the driving unit is greatly saved, and the working efficiency of the processing box is improved.
In some embodiments, the electronic imaging device is further provided with a biasing device that is provided at the lower side of the driving unit 1080 and presses the driving unit 1080 so that the driving unit 1080 maintains the tilted state. The developing cartridge of the present embodiment can align the driving unit 1080 against the biasing force of the biasing means by the pressing member N40 also after the door cover 102 is covered. The deformation of the electrophotographic apparatus is not limited thereto, and the biasing means may also be provided on the upper side of the driving unit 1080. Some electronic imaging devices also eliminate the cam N104, and the electronic imaging device of this structure, to which the process cartridge 1 is mounted, can align the driving unit 1080 without closing the door 102.

Specifically, the cover 1081 includes a front plate 109a, a first side plate 109b, and a second side plate 109c, and the first side plate 109b and the second side plate 109c are connected to the front plate 109a, respectively. Wherein the front plate 109a is provided with a first hole 1090a through which the driving unit 1080 protrudes, the first hole 1090a being a circular hole so that one end of the driving unit 1080 can protrude from the first hole 1090 a. The first side plate 109b is located at an upper side of the front plate 109a, the second side plate 109c is located at a rear side of the front plate 109a, and a second hole 1090b is formed between the first side plate 109b and the second side plate 109c such that a portion of the driving unit 1080 may be exposed to a rear side of the cover 1081 through the second hole 1090 b.
The door cover O102 is rotatably provided on the main assembly O101 to be able to open or close the accommodating portion O105. The door cover O102 is rotatably mounted on the main assembly O101 about a rotation axis, and thus can rotatably open or close the accommodating portion O105. Two sides of the door cover O102 along the axial direction of the rotating shaft are respectively provided with a box pressing member O1020. Each of the two cartridge pressing members O1020 is movable with respect to the door cover O102 within a predetermined range. During the closing of the door cover O102, the cartridge pressing member O1020 can press a force receiving portion O10a (to be described in detail later) provided on the process cartridge 1, so that the process cartridge can be mounted and positioned in the main assembly O101 in a stable posture.
Further, the link member O103, the cam O104 and the driving unit 1080 are located on the same side of the housing portion O105, and the link member O103, the cam O104 and the door cover O102 form a linked relationship to be able to lock or unlock the driving unit 1080 when the door cover O102 performs a closing or opening action.

As shown in fig. 80 and 81, the electronic imaging device further includes a support side plate O82, the support side plate O82 is provided to the main assembly O101, and the support side plate O82 includes a first protrusion O82b and a second protrusion O82c. The driving unit 1080 includes a sliding portion 1080a, the sliding portion 1080a being rotatably supported by a support hole O82a of a support side plate O82. Further, the driving unit 1080 includes a cylindrical portion 1080b, a small diameter portion 1080f, and a power output portion 1080e, the small diameter portion 1080f being connected to an end of the cylindrical portion 1080b, and the small diameter portion 1080f having a diameter smaller than that of the photosensitive drum, an outer surface of one end of the cylindrical portion 1080b near the small diameter portion 1080f being provided with an input gear portion 1080d, and the power output portion 1080e being provided on the small diameter portion 1080f for engagement with the power receiving unit 21 of the process cartridge 1 to transmit the driving force.
During the opening of the door cover O102, the cylindrical cam O104 moves together with the door cover O102, with the result that the cylindrical cam O104 is in contact with the driving unit 1080, and the driving unit 1080 moves together with the cylindrical cam O104 in the direction of arrow H, and then, the abutment surface 1080c of the driving unit 1080 is in contact with at least one of the first protrusion O82b or the second protrusion O82c of the support side plate O82, so that the driving unit 1080 is inclined in the direction of arrow N. When the door cover O102 is in the open state, the driving unit 1080 is in a tilted and locked state, in which the driving unit 1080 is in a retracted position with respect to the front plate 109a, that is, the power output portion 1080e is retracted inside the cover 1081.
When the door cover O102 is closed, the driving unit 1080 is in an unlocked state, and the driving unit 1080 is movable by an external force, that is, is capable of being changed from a tilted state to a straightened state (i.e., a state in which it is not tilted) and is extendable from the cover 1081 by an external force, so that the driving force can be stably transmitted to the process cartridge 1.
The structure of the electronic imaging device is not limited thereto, and some electronic imaging devices are further provided with a biasing device that is located at the lower side or lower side of the driving unit 1080 and presses the upper side or lower side of the driving unit 1080 so that the driving unit 1080 maintains an inclined state.
Fig. 82 is a schematic structural view of the process cartridge of the present embodiment. As shown in fig. 82, the process cartridge 1 includes a cartridge body O10, a photosensitive drum 20, a developing roller 30, and a power receiving unit 21, and in this embodiment, the cartridge body O10 includes a drum frame 12 for supporting the photosensitive drum 20 and a developing frame 11 for supporting the developing roller 30, the drum frame 12 and the developing frame 11 being rotatably connected to each other during operation, and being capable of moving synchronously together during installation of the process cartridge 1. The photosensitive drum 20 is mounted to the drum frame 12, the developing roller 30 is mounted to the developing frame 11, and the photosensitive drum 20 and the developing roller 30 are located on the front side of the process cartridge 1 in the mounting direction, facing each other for performing operations such as development. In this embodiment, the cartridge body O10 further includes an end cap O202, and the end cap O202 is mounted to one end of the drum frame 12. The power receiving unit 21 is provided at the first end 1A of the cartridge body O10, and the power receiving unit 21 includes a power receiving portion O211, the power receiving portion O211 being capable of engaging with the power output portion 1080e to receive the driving force, thereby being capable of driving the developing roller 30 and the photosensitive drum 20 to rotate.
Further, in order to convert the driving unit 1080 from the tilted state of the initial position (in which the rotational axis OL1 of the driving unit 1080 is tilted with respect to the rotational axis OL2 of the photosensitive drum 20) to the aligned state capable of engaging with the power receiving unit 21 (in which the rotational axis of the driving unit 1080 coincides with the rotational axis of the photosensitive drum 20), as shown in fig. 82, the process cartridge 1 further includes a pressing member O40 provided at the first end 1A for applying a pressing force to the driving unit 1080 to bring the driving unit 1080 into the aligned position. Specifically, the urging member O40 is fixedly mounted on the end cap O202 so as to form a fixed connection with the drum frame 12.
Further, in the rotational axis direction OL2 of the photosensitive drum 20, the urging member O40 is located outside the end portion of the power receiving portion O211 so as to be capable of performing a cooperative action with the driving unit 1080 at the time of mounting. As shown in connection with fig. 83, at least a partial projection of the urging portion 402 of the urging member O40 cantilever O42 coincides with the projection of the photosensitive drum 20 or falls into the area of the photosensitive drum 20 on a plane perpendicular to the rotation axis of the photosensitive drum 20.
As shown in fig. 83, the process cartridge 1 further includes a charging roller O60, the charging roller O60 being provided to the cartridge body O10, and the charging roller O60 being rotatable while being in contact with the photosensitive drum 20. In other embodiments, the charging member is not limited to such a rotatable contact roller structure, and for example, a charging member fixed to the photosensitive drum with a certain interval left may be used. As shown in fig. 82, the pressing member O40 is partially located inside the outer peripheral surface of the photosensitive drum 20, and the pressing member O40 is located above a line connecting the rotation center of the charging roller O60 and the rotation center of the photosensitive drum 20.
As shown in fig. 84, the pressing member O40 includes a fixing portion O41 and a cantilever O42, the fixing portion O41 being connected to the cartridge body O10, and the cantilever O42 being connected to the fixing portion O41 and extending toward the photosensitive drum side. Wherein the fixing portion O41 includes mounting projections O401, in the present embodiment, two mounting projections O401 are provided, one of which O401 is located on the upper side of the other mounting projection O401. The end cover O202 is provided with a mounting hole provided corresponding to the mounting projection O401, and when assembled, the mounting projection O401 is engaged with the mounting hole to fix the pressing member O40 to the end cover O202 or the drum frame 12, thereby enabling the pressing member O40 to move with the movement of the drum frame 12. In a state where the process cartridge is mounted to the housing portion O105 of the electronic imaging device, the cantilever O42 passes through the second hole 1090b on the cover 1081 to be able to urge the driving unit 1080 of the electronic imaging device. The shape and structure of the fixing portion is not strictly limited as long as the urging member O40 can be made immovable with respect to the axis of the photosensitive drum 20.
In the present embodiment, the cantilever O42 is substantially rectangular parallelepiped-shaped including an upper end face O42a located on the upper side of the cantilever O42 in the mounted state and a lower end face O42b located on the lower side of the cantilever, the upper end face O42a and the lower end face O42b being arranged in planes parallel to each other, wherein a portion of the lower end face O42b of the free end of the cantilever O42 is configured to urge the driving unit 1080 so as to align the driving unit 1080.
Further, the end of the cantilever O42 away from the fixing portion O41 is further provided with a guide surface in an arc shape connecting the upper end surface O42a and the lower end surface O42b, which is capable of guiding the cantilever O42 to move along the circumferential outer surface of the small diameter portion 1080f of the driving unit 1080 during the closing of the door cover O102 of the electronic imaging device, so as to avoid interference of the cantilever O42 with the driving unit during the mounting of the process cartridge 1. The two side surfaces of the cantilever O42 disposed opposite along the axis OL2 of the photosensitive drum 20 are configured as flat surfaces, and the maximum distance between the two side surfaces is smaller than the width of the second hole 1090b (i.e., the width of the hole along the axis OL2 of the photosensitive drum in the state where the process cartridge is mounted in place) to avoid that the cantilever O42 cannot pass through the second hole 1090b.
With continued reference to fig. 84, it is preferable that the thickness B of the cantilever arm O42 of the pressing member O40 be set to be between 0.6mm and 3.5mm, and if the thickness of the cantilever arm O42 is less than 0.6mm, the structure thereof is too thin, and the cantilever arm O42 is easily broken or broken by the internal structure of the electronic imaging device during the mounting of the process cartridge 1, limited by the distance of the input gear portion 1080d of the driving unit 1080 from the front plate 109a or the space thereof. If the cantilever O42 of the urging member O40 is too thick (greater than 3.5 mm), it is also easy to restrict the distance of the input gear portion 1080d of the driving unit 1080 from the front plate 109a, and the aligning action of the driving unit 1080 cannot be achieved.
Referring to fig. 83, a force receiving portion O10a is further provided at the rear side of the first end 1A of the cartridge body O10, the force receiving portion O10a being for receiving the urging force of the cartridge pressing member O1020 when the door cover O102 is closed, so that the process cartridge 1 is mounted in place.
The following specifically describes a mounting method of the process cartridge into the printer.
As shown in fig. 85, first, the door cover O102 is opened, and the driving unit 1080 is in a locked state with the door cover O102 in an opened state, and the guide protrusions on both sides in the longitudinal direction of the process cartridge 1 are aligned with the guide rails O108 on the first and second side walls of the housing portion O105, so that the process cartridge 1 is pushed in the direction OY1, and the pressing member O40 fixed to the end cover O202 is also gradually moved toward the driving unit 1080 with the movement of the process cartridge 1 until the pressing member O40 comes into contact with the driving unit 1080.
As shown in fig. 86, in a state in which the process cartridge 1 is mounted to the housing portion O105 in the electronic imaging device and the door cover O10 is not closed, the cantilever O42 of the urging member O40 abuts on the upper side of the small diameter portion 1080f of the driving unit 1080. The first end 1A of the process cartridge 1, i.e., the end at which the power receiving unit 21 is located, as viewed from the rear of the process cartridge 1, more upward (the process cartridge 1 is partially tilted upward) in the electronic image forming apparatus than the other end 1B of the process cartridge 1, and the mounting position of the process cartridge at this position is referred to as a first position. The other end 1B of the process cartridge may be in a mounted position at this time.
As shown in fig. 87 and 88, the door O102 of the electronic imaging device is then closed, the cam O104 releases the lock on the driving unit 1080 as the door O102 is closed, the pressing member O1020 inside the door O102 presses the force receiving portion O10a on the rear side of the process cartridge 1, so that the first end 1A of the process cartridge 1 is forced to move down and drive the pressing member O40 to move down, and at this time, the front end of the pressing member O40 presses the driving unit 1080 to move down, so that the rotation axis OL2 of the driving unit 1080 coincides with or is substantially parallel to the rotation axis OL1 of the power receiving unit 21, and the power receiving unit 21 can be engaged with the driving unit, and the process cartridge 1 is at the second position. That is, the driving unit 1080 moves in a direction approaching the power receiving unit 21 upon receiving the pressure. Both ends (1A, 1B) of the process cartridge 1 are maintained in a substantially horizontal state by the pressing force applied to the left and right sides of the process cartridge 1 by the pressing member O1020.
In a state where the process cartridge 1 is mounted in place, the driving unit 1080 is moved from the initial position to a position capable of engaging with the power receiving unit 21, so that the driving unit 1080 transmits driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate, and the mounting position of the process cartridge at this position is referred to as a second position. The force applied by the pressing member O40 to the driving unit 1080 to align the driving unit 1080 may be a force applied to the process cartridge 1 by the pressing member O1020 of the door cover O102 when the door cover O102 is closed, or may be a gravity of the process cartridge 1 itself.
The specific mating action of the urging member O40 and the drive unit 1080 during installation is described below.
As shown in fig. 89, in the process of mounting the process cartridge 1 to the main assembly O101, the urging member O40 may align the driving unit 1080 through the second hole 1090 b. When the process cartridge is not mounted, the driving unit 1080 is in an inclined state, and the rotation axis OL1 of the driving unit 1080 forms an angle α with the central axis OL2 of the first hole. When the driving unit 1080 is aligned, the rotation axis OL1 of the driving unit 1080 substantially coincides with the central axis OL0 of the cover 1081.
When the process cartridge 1 is mounted to the electronic imaging device in the OY1 direction, the lower end face O42b of the cantilever O42 of the urging member O40 urges the small diameter portion 1080f of the driving unit 1080. Since the abutment surface 1080c of the driving unit 1080 is in contact with at least one of the first protrusion O82b or the second protrusion O82c of the support side plate O82, the driving unit 1080 is tilted in the direction of arrow N, i.e., the driving unit 1080 is still in a locked state. When the door cover O102 is closed, the cylindrical cam O104 releases the lock on the driving unit 1080, and the cartridge pressing member O1020 inside the door cover O102 presses the force receiving portion O10a of the process cartridge 1, causing the first end 1A of the process cartridge 1 to be forced. Alternatively, both sides of the cartridge body O10 may be simultaneously biased by the cartridge pressing member O1020. The first end 1A of the process cartridge 1 moves down and drives the pressing member O40 to move down, at which time the lower end face O42b of the cantilever arm O42 of the pressing member O40 presses the small diameter portion 1080f of the driving unit 1080, and likewise, the driving unit 1080 is acted upon by the first protrusion O82b or the second protrusion O82c of the supporting side plate O82, and the driving unit 1080 moves in the opposite direction of the arrow N to be aligned.
As shown in fig. 90 and 91, a connection line of the first boss O82b and the second boss O82c supporting the fulcrum of the driving unit 1080 is defined as OL3, an axis parallel to OL3 and passing through the rotation axis center of the driving unit 1080 is defined as axis OL4, and an axis perpendicular to axis OL4 and passing through the rotation axis center of the driving unit 1080 is defined as axis OL5. During the process cartridge 1 is in the first position and the second position, and the movement from the first position to the second position, the contact force receiving point of the pressing member O40 and the driving unit 1080 when the pressing force F is applied thereto is always located in the upper half of the axis OL 4.
The arrangement position of the pressing member O40 may be changed in many ways, as shown in fig. 92, and when viewed in the left-right direction of the mounting portion, in the first position, the angle between the lower end surface O42b of the cantilever arm O42 of the pressing member O40 and the axis OL5 is β, preferably 78 ° or more β or less than 113 °, and the position of the pressing member O40 on the process cartridge satisfies this condition, the mounting with the electronic imaging device may be achieved, and if the angle is β smaller than 78 ° or larger than 113 °, interference may be caused when the process cartridge 1 is mounted in the electronic imaging device 100, and the process cartridge may not be mounted or the driving unit 1080 may not be aligned.
The processing box with the structure can enable the contact and engagement process of the power receiving unit and the driving unit to be smoother, greatly saves the contact and engagement time of the power receiving unit and the driving unit, ensures more stable transmission of driving force and improves the working efficiency of the processing box.
The process cartridge of the present embodiment is also applicable to the electronic imaging device of the foregoing embodiment.
In the present embodiment, the projection of the cantilever O42 coincides at least partially with the projection of the photosensitive drum 20, and when the process cartridge is mounted to the electronic image forming apparatus, the cantilever O42 is pressed against the small diameter portion 1080f of the driving unit 1080, so that the driving unit 1080 is placed in the normal position, i.e., the cantilever O42 is closer to the rotational axis of the photosensitive drum, so that the driving unit 1080 can be better aligned with the power receiving unit. Meanwhile, the pressing part cantilever part applies an acting force to the small-diameter part of the driving unit, so that the acting force applied by the pressing part cantilever part is smaller and more accurate, and the driving unit is aligned from an inclined position to a position close to the coaxial with the photosensitive drum, so that the contact and engagement process between the photosensitive drum or the developing roller of the processing box and the driving unit of the electronic imaging device is smoother, the contact and engagement time between the photosensitive drum or the developing roller and the driving unit is greatly saved, and the working efficiency of the processing box is improved.

The pressing piece is arranged on the same end of the box body and is positioned at the same end of the box body with the power receiving unit, and the pressing piece can generate displacement relative to the box body so as to swing the position of the driving unit of the positron imaging device, so that the driving unit and the power receiving unit can be meshed, and the output driving force of the driving unit is transmitted to the photosensitive drum and the developing roller.
In the present embodiment, the power receiving unit is connected to the photosensitive drum, it will be understood that in other embodiments, the power receiving unit may be connected to the developing roller, or two power receiving units may be provided, one of which is connected to the photosensitive drum and the other of which is connected to the developing roller.

The direction substantially parallel to the axial direction of the photosensitive drum may be a direction forming an angle with the axial direction of the photosensitive drum, and the angle may be within ±5°.
Further, the pressing member S40 includes a rod coaxially disposed with the photosensitive drum 20 and a protrusion S41 formed by bending and extending from one end of the rod, the rod is connected to the box body through an elastic member S60, the protrusion S41 is disposed near the power receiving unit 21, and is used for pressing a driving unit of the electronic imaging device, so that the driving unit and the power receiving unit 21 are substantially coaxially engaged to transmit power.
When the elastic member S60 is in a compressed state, the pressing member S40 can move axially along the length direction of the process cartridge 1 or the photosensitive drum 20 such that the pressing member S40 is away from the driving unit 1080. When the elastic member S60 is in the relaxed state, the pressing member S40 can move axially along the length direction of the process cartridge 1 or the photosensitive drum 20, so that the pressing member S40 approaches the driving unit 1080 and drives the driving unit 1080 to press down.

Example twenty
In this embodiment, another process cartridge is provided, and the non-illustrated portions are the same as those in the foregoing embodiments, so that the description is omitted for brevity.
This embodiment differs from the above embodiments in that: the pressing member in the process cartridge of this embodiment is sleeved outside the power receiving unit and rotates coaxially with the photosensitive drum.
Specifically, as shown in fig. 107 and 108, the process cartridge further includes a retracting mechanism T70 and a pressing member T40, the power receiving unit 21 is connected to one end of the photosensitive drum 20, the retracting mechanism T70 is provided inside the photosensitive drum 20, and the power receiving unit 21 is connected to the photosensitive drum 20 via the retracting mechanism T70, so that the power receiving unit 21 can move in the axial direction of the photosensitive drum 20. Alternatively, the telescopic mechanism T70 is an elastic member, which may be a spring, a magnet, an elastic sponge, or other elastic members, which is not limited herein.
In this embodiment, the elastic member is a spring, and the end of the photosensitive drum 20 is provided with a groove 20a, and the spring is accommodated in the groove 20a at the end of the photosensitive drum 20.
The pressing member T40 is sleeved on the outer side of the power receiving unit 21 away from the telescopic mechanism T70, and the pressing member T40 can coaxially rotate with the photosensitive drum 20, so that the pressing member T40 can move along with the power receiving unit 21 in the axial direction of the photosensitive drum 20. In this embodiment, the pressing member T40 is a rotatable sleeve, which may be hollow cylindrical, and the power receiving unit 21 is accommodated in the sleeve and is movable along the sleeve.
Specifically, one end of the telescopic mechanism T70 (elastic member) abuts against the inner wall of the groove 20a, and the other end of the telescopic mechanism T70 (elastic member) abuts against the power receiving unit 21.
When the process cartridge is not mounted in the electronic imaging device, the power receiving unit 21 can resist the elastic force of the retracting mechanism T70 by the frictional force between the power receiving unit 21 and the urging member T40, and retract to be accommodated in the urging member T40. When the process cartridge is mounted in the electrophotographic apparatus, the driving unit 1080 is in an inclined state at this time, i.e., the axis of the driving unit 1080 is not parallel to the axis of the photosensitive drum 20, and since the urging member T40 is fitted to the outside of the power receiving unit 21, the urging member T40 and the driving unit 1080 form a structural interference, and at this time, the driving unit 1080 starts to rotate and drives the urging member T40 to rotate. In the process of rotating the pressing member T40, centrifugal force generated by the pressing member T40 gradually moves the driving unit 1080 from the original inclined state to a position where the axis of the driving unit 1080 coincides with the axis of the photosensitive drum 20, at this time, the driving unit 1080 is coaxial with the photosensitive drum 20, after the pressing member T40 rotates centrifugally, friction force between the power receiving unit 21 and the pressing member T40 is reduced, the power receiving unit 21 is driven to move along the axial direction of the photosensitive drum 20 towards a direction approaching the driving unit 1080 by using elastic force of the telescopic mechanism T70, and the power receiving unit 21 is extended from the pressing member T40 by the movement of the power receiving unit 21, so that the driving unit 1080 is successfully meshed with the driving unit 1080, and power transmission between the driving unit 1080 and the photosensitive drum 20 is realized.

Of course, a conventional structure such as a restriction structure may be provided so that the power receiving unit U22 and the urging member U23 do not come out of the process cartridge, thereby realizing that the power receiving unit U22 and the urging member U23 can translate in the axial direction of the photosensitive drum. In the present embodiment, the initial state of the first elastic member U211 is a state in which the power receiving unit U22 and the urging member U23 are compressed to extend into the process cartridge. The second elastic member U231 acts only on the pressing member U23, and the ability of the pressing member U23 to expand and contract in the direction perpendicular to the axial direction of the photosensitive drum is imparted by the second elastic member U231, so that the pressing member U23 can be displaced in the direction perpendicular to the axial direction of the photosensitive drum, not limited to being moved only in the direction perpendicular to the axial direction. The second elastic member U231 may be disposed in a similar manner to the first elastic member U211, and one end of the second elastic member U231 may be disposed on the inner wall of the driving gear or on the power receiving unit U22, in this embodiment, on a wall surface U220 inside the power receiving unit U22, and the other end of the second elastic member U231 is directly or indirectly disposed on the pressing member U23, where the pressing member U23 is in a state of being compressed in a direction perpendicular to the axial direction of the photosensitive drum, and when the second elastic member U231 releases the elastic force (e.g., stretches), the pressing member U23 may translate in a direction perpendicular to the axial direction of the photosensitive drum away from the power receiving unit U22, and when the second elastic member U231 is deformed (e.g., compressed), the pressing member U23 may translate in a direction perpendicular to the axial direction of the photosensitive drum toward the power receiving unit U22. For setting and maintaining the initial state of the second elastic member U231, a limiting portion U2311 is preferably provided, and the limiting portion U2311 is a block-shaped or bar-shaped member fixedly provided at the case for limiting the position of the pressing member U23. In this embodiment, the limiting portion U2311 of the strip member "holds" the pressing member U23, that is, the second elastic member U231 compresses and makes the pressing member U23 abut against the limiting portion U2311, and the pressing member U23 and/or the second elastic member U231 can move relative to the limiting portion U2311, and the moving manner may be that the pressing member U23 and/or the second elastic member U231 slides on the limiting portion U2311.
Further, the process cartridge further includes a lever U810 for receiving an external force such as that caused when the door 13 of the electrophotographic apparatus is closed, and a rotatable buckle U820 for controlling the above-mentioned power receiving unit U21 to extend out of the process cartridge in the axial direction of the photosensitive drum, the buckle U820 being provided to the cartridge body rotatably around the rotational axis U821, and the movement of the power receiving unit U21 in the axial direction of the photosensitive drum being blocked by the buckle U820. As shown in fig. 110, when the process cartridge is mounted in the electrophotographic apparatus, the driving unit 1080 is in an inclined state, i.e., the axis of the driving unit 1080 is not parallel to the axis of the photosensitive drum 20, and when the door cover 13 is closed such that the control lever U810 controls the above-mentioned power receiving unit 21 to protrude from the process cartridge in the axial direction of the photosensitive drum, as in the motion changing process of fig. 110 to 111, first, the power receiving unit U22 may be blocked from protruding by the buckle U820 and the pressing member U23 may be protruded, at which time the extension of the first elastic member U211 is not affected, or the first elastic member U211 may be provided in two parts to control the power receiving unit U22 and the pressing member U23, respectively. Further, when the pressing member U23 and/or the second elastic member U231 move away from the power receiving unit U22, the pressing member U23 and the fixed limiting portion U2311 are also relatively displaced, and when the pressing member U23 moves from the state of fig. 111 to the state of fig. 112, the limiting portion U2311 is released, in this embodiment, the pressing member U23 and/or the second elastic member U231 slide out of the limiting portion U2311 during the movement, for example, may be separated from the limiting portion U2311 and be out of contact with the limiting portion U2311, so as to be out of limitation of the limiting portion U2311, during this process, the pressing member U23 is extended outwards to be capable of abutting against the driving unit 1080, a certain pressing force is formed on the driving unit 1080 by the pressing member U23, and the driving unit 1080 is guided to gradually rotate and align until the state shown in fig. 112 is formed, at this time, the pressing member U23 is completely extended outwards and abuts against the driving unit 1080, so that the driving unit 1080 moves from the inclined state to a position where the axis of the pressing member U23 is substantially parallel to or coaxial with the axis of the photosensitive drum 20, and the driving unit 1080 is not completely engaged with the power receiving unit 1080. Further, as shown in fig. 113, when the buckle U820 of the present embodiment is triggered or automatically rotated, its blocking effect on the power receiving unit U22 is released, so that the power receiving unit U22 is protruded outside the process cartridge by the stretching effect of the first elastic member U211, thereby smoothly contacting and engaging with the aligned driving unit 1080, and this state completes the complete engagement of the power receiving unit 21 and the driving unit 1080.
Further, an inclined plane U2312 (e.g., a free end) may be further disposed on the limiting portion U2311, for assisting the urging member U23 to return in the axial direction of the photosensitive drum and the direction perpendicular to the axial direction of the photosensitive drum.
Further, in the motion changing process as shown in fig. 110 to 111, the present embodiment may not rely on the buckle U820 to block the movement of the power receiving unit U22 in the axial direction of the photosensitive drum, but may perform the blocking function through the driving unit 1080 or the driving unit protecting cover 1081 located outside the driving unit 1080, that is, the power receiving unit U22 is directly blocked by the end portion of the driving unit 1080 or the driving unit protecting cover 1081, and after being aligned, protrudes further outwards to complete the engagement, which may also complete the purpose of the present embodiment.

Specifically, as shown in fig. 119, the fitting relationship between the power receiving unit 21 and the carrier V50 is: the force receiving portion V22 is mounted to the groove V231 of the force transmitting portion V23 through the protrusion V222 so as to be fixed to the force transmitting portion V23 and so that the force receiving portion V22 can slide in the LL direction (direction parallel to the groove V231 in fig. 119) through the groove V231 and can move together with the force transmitting portion V23 upon receiving the driving force of the electronic imaging device, while the two first fixing posts V223 of the force receiving portion V22 and the two second fixing posts V233 of the force transmitting portion V24 are connected by the first elastic member V61 so that the force receiving portion V22 can be reset when no longer receiving the driving force. Wherein the force receiving portion V22 is caused to protrude toward the outside of the process cartridge 1 with respect to the force transmitting portion V23 when the first elastic member V61 is in the natural state. The force transmission part V23 is disposed in the accommodating part V242 of the flange V24, at this time, the limiting surface V234 of the force transmission part V23 abuts against the accommodating part V242, the positioning post V243 in the flange V24 is connected with the connecting part V232 of the force transmission part V23 through the second elastic member V63, so that the force receiving part V22 movably connected with the force transmission part V23 can be biased in a predetermined phase, and the swinging member V244 is used for contacting with the second elastic member V63 to prevent the force receiving part V22 from being unable to return when the force transmission part V23 rotates after receiving power from the force receiving part V22. At this time, the respective parts of the power receiving unit 21 may be mounted together in the carrier V50 after being sequentially mounted, the force transmitting portion V23 passes through the through hole V52 of the carrier V50 so that the power receiving unit 21 is fixed to the carrier V50, while the third elastic member V64 is fitted over one end of the force transmitting portion V23 passing through the through hole V52, one end of the third elastic member V64 abuts against the carrier V53 of the carrier V50, the other end abuts against the clutch member V80, wherein the clutch member V80 is connected to the force transmitting portion V23 through a shaft pin (not shown) passing through the notch V235, and a plurality of second protrusions V81 are provided in a circumferential arrangement on one end of the clutch member V80 facing the carrier V50. The above-described individual parts are integrally assembled in the photosensitive drum 20 after being fitted to each other, see fig. 119.
In this embodiment, the urging member is integrated with the power receiving portion, and the power receiving portion V22 is movable in the first plane area in the first direction for engaging with the driving unit 1080 and aligning the driving unit. Wherein, on the plane perpendicular to the photosensitive drum axial direction, the projection of the first plane area is at least partially overlapped with the projection of the photosensitive drum, and the first direction intersects with the photosensitive drum axial direction and is not perpendicular, namely, the LL direction in FIG. 119.
The process of contact engagement and disengagement of the power receiving unit of the process cartridge with the driving unit of the electrophotographic image forming apparatus is described below.
As shown in fig. 119 and 120, when the process cartridge 1 is not yet mounted in the electrophotographic image forming apparatus or when no external force is received after being mounted in the electrophotographic image forming apparatus, the power receiving unit 21 at this time is in an initial state in which the force receiving portion V22 protrudes with respect to the flange V24 in the axial direction of the photosensitive drum 20 by the first elastic member V61.
As shown in fig. 121, when the process cartridge 1 is mounted in the electronic imaging device and the door is closed, the control mechanism V30 on the process cartridge is moved in the X direction by an external force, while the inclined surface V322 on the second end V32 of the control mechanism V30 is moved to a position contacting the abutment surface V2411 of the flange V24, as the control mechanism V30 continues to move, the inclined surface V322 successfully abuts the abutment surface V2411 and gives a force in the X direction to the flange V24, since the stopper surface V234 of the force transmitting portion V23 abuts the receiving portion V242 of the flange V24 and the clutch member V80 is movably connected with the force transmitting portion V23, the force transmitting portion V23 moves in the Y4 direction (i.e., a direction toward the driving unit 1080) together with the force receiving portion V22 and the clutch member V80, while the force receiving portion V22 moves in the Y4 direction to a position abutting the driving unit 1080 in the electronic imaging device, i.e. the projection V221 of the force receiving part V22 is snapped into the drive unit 1080 in the electronic imaging device, at which time the drive unit 1080 in the electronic imaging device is still in an inclined state, while the flange V24 drives the force transmitting part V23 together in the Y4 direction as the control mechanism V30 continues to move in the X direction, whereas the force receiving part V22 at this moment, because it has been connected with the drive unit 1080, is no longer able to move with the force transmitting part V23 in the Y4 direction, but rather moves relatively to the force transmitting part V23, i.e. to the flange V24, through the groove V231 of the force transmitting part V23, while the force receiving part V22 translates in the drive unit 1080, which translates in a radial direction with respect to the drive unit 1080, and thereby drives the drive unit 1080 to move when the projection V221 of the force receiving part V22 abuts into the side of the recess in the drive unit 1080, so that the driving unit 1080 is moved from the initial inclined state to a position where its axis is substantially parallel or coaxial with the axis of the photosensitive drum 20.
As shown in fig. 122 and 123, as the control mechanism V30 is moved into position, the position where the flange V24 abuts against the driving unit protecting cover 1081 is not moved, and the clutch member V80 at this time is also moved to a position where it contacts the carrier member V50 against the elastic force of the third elastic member V64, the second protrusion V81 of the clutch member V80 is successfully engaged with the first protrusion V53 of the carrier member V50, and at this time the force receiving portion V22 also moves the driving unit 1080 to a position coaxial with the photosensitive drum 20, thereby achieving transmission of driving force between the driving unit 1080 and the photosensitive drum.
When the door of the electronic imaging device is opened, the external force applied to the control mechanism V30 disappears, the flange V24 is retracted in the direction opposite to the Y4 direction and moves together with the power transmission portion V23, the clutch member V80 is also moved in the direction opposite to the Y4 direction, the third elastic member V64 is reset after losing the force of the clutch member V80, the force receiving portion V22 is disengaged from the driving unit 1080, and finally the power receiving unit 21 is restored to the original state, so that the process cartridge can be successfully removed from the electronic imaging device.
Examples twenty-three
The present embodiment provides another control mechanism, which is a further improvement based on the twenty-second embodiment, and the non-illustrated parts are the same as those in the foregoing embodiments, so that the description is omitted for brevity.
As shown in fig. 124, the control mechanism W30 is movably disposed at an end of the case, and specifically, the control mechanism W30 includes a first end W31, a second end W32, and a shaft hole W33, wherein a slope W322 is disposed at an end of the second end W32. Alternatively, the control mechanism W30 may be movably coupled to an end cap (not shown) through a shaft hole W33 so as to be fixed to the cartridge body, so that the control mechanism W30 is caused to swing on a plane perpendicular to the axial direction of the photosensitive drum 20.
In addition, the control mechanism on the process cartridge may be a power source, and when the control mechanism is a power source, an instruction may be obtained by an action of closing the door cover of the electronic imaging device, so that the operation flange and the force receiving portion and the force transmitting portion protrude in the direction of the driving unit, and the power receiving unit 21 may be controlled to stop after a certain stroke of protrusion. Alternatively, the power source may be an electric motor, a photodynamic power, or the like.
A process of contact engagement of the power receiving unit with the driving unit of the electronic imaging device: when the process cartridge has not been mounted in the electronic imaging device or receives no external force after being mounted in the electronic imaging device, the power receiving unit 21 is in an initial state in which the force receiving portion V22 protrudes with respect to the flange V24 in the axial direction of the photosensitive drum 20 by the first elastic member V61.
When the process cartridge 1 is mounted in the electronic imaging device and the door is closed, the control mechanism W30 on the process cartridge swings in a plane perpendicular to the axial direction of the photosensitive drum 20 by an external force, at this time, the inclined surface W322 on the second end W32 of the control mechanism W30 moves to a position contacting the abutment surface V2411 of the flange V24, as the control mechanism W30 continues to move, the inclined surface W322 successfully abuts the abutment surface V2411 and gives a force in the X direction to the flange V24, since the limit surface V234 of the force transmitting portion V23 abuts the accommodating portion V242 of the flange V24 and the clutch member V80 is movably connected with the force transmitting portion V23, the force transmitting portion V23 moves in the Y4 direction (i.e., toward the driving unit 1080) together with the force receiving portion V22 and the clutch member V80, at this time, the force receiving portion V22 moves in the Y4 direction to a position abutting the driving unit 1080 in the electronic imaging device, i.e. the projection V221 of the force receiving part V22 is snapped into the drive unit 1080 in the electronic imaging device, at which time the drive unit 1080 in the electronic imaging device is still in an inclined state, while with continued movement of the control mechanism W30 the flange V24 drives the force transmitting part V23 together in the Y4 direction, whereas at this moment the force receiving part V22, as having been connected with the drive unit 1080, is no longer able to continue to move with the force transmitting part V23 in the Y4 direction, but is moved relatively to the force transmitting part V23, i.e. to the flange V24, by means of the groove V231 of the force transmitting part V23, while the force receiving part V22 is translated in the drive unit 1080, which translation is a movement in a radial direction with respect to the drive unit 1080, and thereby drives the drive unit 1080 to move when the projection V221 of the force receiving part V22 abuts into the recess in the drive unit 1080, so that the driving unit 1080 is moved from the initial inclined state to a position where its axis is substantially parallel or coaxial with the axis of the photosensitive drum 20.
As the control mechanism W30 moves into position, the position where the flange V24 abuts against the driving unit protecting cover 1081 is not moved, and the clutch member V80 is moved to a position where it contacts the carrier member V50 against the elastic force of the third elastic member V64, and the second protrusion V81 of the clutch member V80 is successfully engaged with the first protrusion V53 of the carrier member V50, and at this time, the force receiving portion V22 also moves the driving unit 1080 to a position coaxial with the photosensitive drum 20, thereby achieving transmission of driving force between the driving unit 1080 and the photosensitive drum.
When the door of the electronic imaging device is opened, the external force applied to the control mechanism W30 disappears, the flange V24 is retracted in the direction opposite to the Y4 direction and moves together with the power transmission portion V23, the clutch member V80 is also moved in the direction opposite to the Y4 direction, the third elastic member V64 is reset after losing the force of the clutch member V80, the force receiving portion V22 is disengaged from the driving unit 1080, and finally the power receiving unit 21 is restored to the original state, so that the process cartridge can be successfully removed from the electronic imaging device.

As shown in fig. 133 and 134, when the process cartridge 1 is mounted in the electronic imaging device in the Y1 direction, since the pressing member Y40 is brought into contact with the driving unit protecting cover 1081 located above the driving unit 1080 in the electronic imaging device to interfere with the driving unit protecting cover 1081, the pressing member Y40 is moved in the opposite direction to the YI direction by the force of the driving unit protecting cover 1081, and the elastic member Y60 is pressed, while the side end of the process cartridge is moved up there to tilt the process cartridge, as shown in fig. 135, as the process cartridge 1 is further mounted, the pressing member Y40 is moved up over the driving unit protecting cover 1081 and then moved to the opening above the driving unit protecting cover 1081, at this time, the guiding surface Y41 of the pressing member Y40 abuts against the driving unit protecting cover 1081, and the pressing member Y40 is smoothly inserted into the opening of the driving unit protecting cover 1081 under the guiding of the guiding surface Y41, and as the front end of the process cartridge 1 is moved down and drives the pressing member Y40 to move down, at this time, the front end of the pressing member Y40 moves down to be coaxial with the power receiving unit 21 to receive the power substantially the power to successfully mount the process cartridge 1 in the electronic imaging device.
When the process cartridge is to be removed from the image forming apparatus after use, alternatively, the user may first press the handle Y70 of the process cartridge (counterclockwise as indicated by the arrow in fig. 136), which rotates counterclockwise about the photosensitive drum 20, and the pressing member Y40 fixed relative to the process cartridge moves accordingly, so that the pressing member Y40 can be successfully disengaged from the driving unit protecting cover 1081 while avoiding the interference of the driving unit protecting cover 1081, and then continue to pull out the process cartridge in the direction opposite to the mounting direction, as shown in fig. 137, to finally enable the process cartridge to be smoothly removed from the image forming apparatus.

Fig. 155 is a schematic structural view of a process cartridge in twenty-ninth embodiment, and fig. 156 is a schematic partial view of a first gear in twenty-ninth embodiment.

During the contact engagement of the power receiving unit 21 with the driving unit of the electronic imaging device, the pressing member CC40 can be brought into contact with the driving unit 1080 to thereby perform the alignment of the driving unit, that is, the driving unit of the positron imaging device can be aligned by the pressing member CC40, wherein the alignment of the driving unit refers to a position in which the axis of the driving unit is substantially parallel or coaxial with the axis of the photosensitive drum.
In the present embodiment, the pressing element CC40 is integrally formed with the bracket, and it is understood that in other embodiments, the pressing element CC40 may be movably connected to the bracket and fixed to the bracket, so that the driving unit 1080 may be moved between the tilted position and the aligned position by the pressing element CC 40. That is, when the process cartridge is just started to be mounted in the electrophotographic apparatus, the driving unit 1080 is inclined with respect to the photosensitive drum axis, the pressing portion of the pressing member CC40 abuts against the driving unit 1080, and when the process cartridge is continuously mounted, the pressing portion of the pressing member CC40 applies a force to the driving unit 1080, thereby bringing the driving unit 1080 to the aligned position, and displacing the pressing member CC40 to a certain extent with respect to the photosensitive drum.
With continued reference to fig. 156, the first gear CC32 has protrusions CC32a, and the protrusions CC32a are spirally distributed.

Fig. 158a is a schematic view of a process cartridge in which the photosensitive drum power receiving unit is not in contact engagement with the driving unit in the electrophotographic apparatus in twenty-ninth embodiment.

In the present embodiment, the third gear CC211 is integrally formed with the power receiving unit 21.
In the process of mounting the process cartridge 1 to the electronic imaging device, at the beginning, the pressing member CC40 mounted on the carriage gradually approaches the driving unit 1080 of the electronic imaging device along with the movement of the process cartridge, but does not contact the small diameter portion of the driving unit 1080, as shown in fig. 158a, at this time, the pressing member CC40 is in a state of being far away from the driving unit 1080, the driving unit 1080 is still in an inclined state, and the gear portion 1080a of the driving unit 1080 is not in contact with the protrusion CC32a of the first gear CC 32. Further, in a state in which the driving unit of the electronic imaging device has not been set, the axis L1 of the driving unit 1080 is in a non-parallel state with the axis L2 of the photosensitive drum 20, specifically, the driving output portion 1080b of the driving unit 1080 of the electronic imaging device is not aligned with the power receiving unit, i.e., the power receiving unit 21 of the process cartridge is not in contact engagement with the driving unit 1080 of the electronic imaging device.
When the pressing member CC40 is brought into contact with the driving unit 1080 of the electronic imaging device to form structural interference during the further mounting, the pressing member CC40 applies an aligning force to the driving unit 1080 of the electronic imaging device, the pressing member CC40 has a downward state, the driving unit 1080 is pressed to align, as shown in fig. 158b, at this time, the pressing member CC40 is brought close to the driving unit 1080 of the electronic imaging device, the driving unit 1080 of the electronic imaging device is aligned, the axis L1 of the driving unit 1080 is brought into parallel with the axis L2 of the photosensitive drum 20 in the aligned state of the driving unit 1080, which can be said to be in a coaxial state, and in this state, the gear portion 1080a of the driving unit 1080 is meshed with the first gear CC32, and since the gear portion 1080a of the driving unit 1080 has helical teeth, and the protrusions CC32a of the first gear CC32 are also spirally distributed, so that in the meshed rotation state of the driving unit 1080 and the first gear CC32, the driving unit 1080 moves in a direction approaching the power receiving unit 21.
Specifically, the driving output portion 1080c of the driving unit 1080 of the electronic imaging device is aligned with the power receiving portion CC21a of the power receiving unit 21, that is, the power receiving unit is in contact engagement with the driving unit, so that the driving unit 1080 transmits the driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate, and then transmits the driving force to the developing roller 30 through the third gear CC211 and the second gear 31, so that the rotation of the developing roller 30 is realized.
Fig. 159 is a schematic view showing a driving unit and a first gear in contact with each other in an electronic imaging device according to twenty-ninth embodiment. As shown in fig. 159, in a state in which the driving unit 1080 and the first gear CC32 of the electronic imaging device are in meshed rotation, the meshing of the spiral teeth of the gear portion 1080a of the driving unit 1080 and the protrusions CC32a of the first gear CC32 generates an axial force F1, and the driving unit 1080 tends to move to a side closer to the power receiving unit 21 by the axial force F1, that is, the driving unit 1080 approaches and contacts the power receiving portion CC21a of the power receiving unit 21. At the same time, the first gear CC32 receives the axial force F2 due to the engagement, so that the first gear CC32 tends to move to the side away from the power receiving unit 21, and since the first gear CC32 is limited by the structure of the process cartridge 1, it does not undergo the axial movement.

In the practical application process, the pressing member DD40 abuts against the driving unit 1080 through the pressing portion DD44, and the driving unit 1080 is adjusted from the tilted state to the aligned state. When the pressing part DD44 of the pressing part DD40 abuts against the driving unit 1080, the deformable part DD42 deforms, and the pressing part DD40 drives the driving unit 1080 to adjust from the inclined state to the aligned state under the deformation force of the deformable part DD42, and the deformation of the deformable part DD42 is recovered.
In some embodiments, the urging member DD40 further includes an abutment portion DD43, the abutment portion DD43 being located at an end of the deformable portion DD42 remote from the first body portion DD 41. Specifically, the abutting portion DD43 may be formed by bending from one end of the deformable portion DD 42. The contact portion DD43 can contact the driving unit protection cover 1081.
When the driving unit 1080 is in the aligned state, the abutting portion DD43 abuts against the driving unit protecting cover 1081, so that the pressing portion DD44 is no longer in contact with the driving unit 1080, and the driving unit 1080 does not generate friction or even interference with the pressing member DD40 during rotation operation. Therefore, the pressing piece DD40 provided by the application does not influence the rotation work of the driving unit 1080, can avoid friction damage of the pressing piece DD40 and the driving unit 1080, and can prolong the service life of the pressing piece DD 40.
In order to improve the mounting stability of the pressing member DD40 and the driving unit protecting cover 1081, as shown in fig. 162, the pressing member DD40 further includes a fixing portion by which the pressing member DD40 is detachably mounted on the driving unit protecting cover.
Specifically, the fixing portion includes a first fixing end DD45 and a second fixing end DD46 formed by bending along two ends of the first main body portion DD41, and the pressing member DD40 is clamped on a side wall of the driving unit protection cover 1081 through the first fixing end DD45 and the second fixing end DD 46. The first and second fixed ends DD45 and DD46 may be a snap hook structure.
Fig. 163 is a schematic structural view of the electronic imaging device provided by the present application after the pressing member is mounted, fig. 164 is a partially enlarged view of a region B shown in fig. 163, and fig. 165 is a schematic structural view of an assembly between the pressing member and the protective cover of the driving unit provided by the present application. As shown in fig. 163, 164 and 165, the driving unit protection cover 1081 is recessed along the axial direction to form a groove, in this embodiment, the groove includes a first groove 1081a and a second groove 1081b that are disposed at intervals, the first groove 1081a includes a first end wall 10811, the second groove 1081b includes a second end wall 10812, the first fixed end DD45 abuts against the first end wall 10811, and the second fixed end DD46 abuts against the first end wall 10812, so that the pressing member is mounted on the driving unit protection cover 1081.
In this embodiment, the first fixing end DD45 and the second fixing end DD46 are both of a hook structure, and are detachably connected with the driving unit protection cover 1081 through the hook structure, so that the installation and replacement are convenient.
In order to further improve the stability of the overall structure, the first end wall 10811 and the second end wall 10812 may further be provided with a clamping rib, and the first fixing end DD45 and the second fixing end DD46 may be provided with a protrusion or a groove in a matched manner, so that the clamping connection is more stable.
In other embodiments, the first end wall 10811 and the second end wall 10812 may also be walls extending in the axial direction of the drive unit casing 1081, or alternatively other side walls, without limitation. The fixing of the pressing member DD40 on the driving unit protecting cover 1081 along the axis L2 may be not limited, for example, by adjusting the width dimension of the first main body portion DD41 of the pressing member DD40 to be tightly matched with the axial dimension of the driving unit protecting cover 1081, so as to avoid the axial shake of the pressing member DD40 on the driving unit protecting cover 1081.
As shown in fig. 163 and 164, before the pressing member DD40 is individually installed in the printer, at this time, the door cover of the printer is opened, and the driving unit 1080 is not set by an external force but is still in an inclined state, at which time the pressing member DD40 may be manually installed to the driving unit protecting cover 1081.
As shown in fig. 163 and 165, when the pressing member DD40 is fed into the printer in the direction of arrow M in fig. 163 and contacts the upper side of the driving unit protecting cover 1081, the first fixed end DD45 is engaged with the first end wall 10811 of the driving unit protecting cover 1081 and the second fixed end DD46 is engaged with the second end wall 10812 of the driving unit protecting cover 1081 by applying a certain pressing force to the pressing member DD 40. As shown in fig. 164, the pressing member DD40 contacts the driving unit 1080 via the pressing portion DD44, and the door is not closed, the pressing member DD40 abuts against the driving unit 1080 in the tilted state, and the deformable portion DD42 is deformed adaptively and maintained in the deformed state by the portion of the driving unit 1080 that is tilted away from the outer periphery of the driving unit cover 1081 abutting against the pressing portion DD44, and at this time, the deformation restoring force generated by the deformation of the deformable portion DD42 is always applied to the driving unit 1080, and the entire state of the pressing member DD40 is the first state, and the driving unit 1080 is adjusted from the tilted state to the aligned state.
Further, in order to facilitate the mounting and the cooperation with the process cartridge, the process cartridge provided by the present application further comprises a cartridge pressing member AB40, and the cartridge pressing member AB40 is disposed at one end of the process cartridge.
Fig. 166 is a schematic view of a partial structure of a printer according to an embodiment of the present application, fig. 167 is an enlarged partial view of a region C shown in fig. 166, and fig. 168 is a schematic view of a process cartridge according to an embodiment of the present application. As shown in fig. 166 to 168, the process cartridge provided by the present application may be any process cartridge capable of working in cooperation with the pressing member, and the specific structure of the process cartridge is not limited by the present application. As shown in fig. 168, in some embodiments, the process cartridge has a swingable cartridge pressing member AB40 thereon, and in addition, the process cartridge according to this embodiment may not have any pressing structure such as the cartridge pressing member AB40, so that the pressing member in this embodiment has general applicability in cooperation with the process cartridge.
Specifically, when the process cartridge in fig. 168 is mounted in the printer in the same mounting direction as the above-described pressing member DD40, i.e., in the direction of the arrow M, is fed into the electrophotographic apparatus, as shown in fig. 166 and 167, the mounted process cartridge may be mounted in a position of the pressing member DD40, with the cartridge pressing member AB40 thereof being directly above the pressing member DD40, for example, overlapping the pressing member DD40, and at this time, since the thickness of the pressing member DD40 in the direction of the vertical axis L2 of the present embodiment is sufficiently small, the pressing member DD40 does not affect the cartridge pressing member AB40 and its functions on the process cartridge, i.e., can be adapted to process cartridges of various structures.
Further, describing the state when the process cartridge is in operation, as shown in fig. 169, when the door of the printer is closed, the driving unit 1080 is brought into a state that can be swung by an external force, whereupon the deformation restoring force of the deformable portion DD42 applied to the driving unit 1080 brings the driving unit 1080 and adjusts it from the tilted state to the aligned state, and the photosensitive drum power receiving head (not shown) on the process cartridge can be brought into good engagement with the driving unit 1080 gradually with the alignment of the driving unit 1080. At this time, the restoring of the deformable portion DD42 moves the abutting portion DD43 to abut against the driving unit protecting cover 1081, so that the pressing portion DD44 is no longer in contact with the driving unit 1080, and the driving unit 1080 does not generate friction or even interference with the pressing member DD40 during the rotation operation, and is in the second state of the pressing member DD40, so that the subsequent normal printing operation can be performed.

To facilitate the installation of the pressing assembly E90, the pressing assembly EE90 is adapted to the width of the cartridge receiving chamber in the printer body. When the pressing assembly EE90 is installed into the inside of the printer body, the first end EE92 and the second end EE93 of the frame EE91 are respectively connected with both end walls of the process cartridge accommodating chamber of the electronic imaging device (e.g., printer). In some embodiments, the frame may be mounted on corresponding structures of two end walls of the cartridge receiving chamber of the printer.

According to the pressing assembly provided by the application, the pressing element can be independently and detachably arranged in the printer or can be detachably arranged in the printing together with the frame. When the pressing member is detachably mountable to the printer alone, the pressing member may be first mounted to the printer, the process cartridge may be then mounted to the printer, and the pressing member may be removed from the printer, as applicable but not limited to removing the pressing member during a door closing operation, and not limited to simultaneously adjusting the drive unit 1080 from an inclined state to an aligned state by other structural cooperation on the process cartridge.

Fig. 171 is another schematic structural diagram of an urging assembly according to an embodiment of the present application, and as shown in fig. 171, an urging assembly FF90 is detachably mounted on a driving unit protection cover 1081. The pressing assembly FF90 includes: comprises a second main body part FF91, a pressing piece FF40 and a deformable piece FF92 which are arranged on the second main body part FF 91. Wherein, the pressing member FF40 is connected with the second main body portion FF91 through the deformable member FF92, and the pressing member FF40 reciprocates under the deformation of the deformable member FF92.
The second main body portion FF91 may be a thin plastic member, a sheet metal member, or the like, and the present application is not limited as long as the installation thereof, and the deformation and recovery of the pressing member FF40 and the deformable member FF92 are not affected. Specifically, positioning structures are disposed on two sides of the second main body portion FF91, and the positioning structures are cooperatively connected with connection structures on two sides inside the printer, and the connection structures on two sides of the printer may be structures such as a guide rail and a sidewall step. When the second main body portion FF91 is mounted to the printer with the positioning structure, the positioning structure is engaged with the connection structure of the printer.
Fig. 172 is a schematic structural diagram of a pressing assembly according to an embodiment of the present application, and as shown in fig. 172, the second main body portion FF91 may further be provided with a handle for facilitating installation and holding of the pressing assembly.
Further, at least one end of the second main body portion FF91 is provided with a positioning structure, and the pressing assembly is detachably mounted in a process cartridge mounting cavity of the electronic imaging device through the positioning structure. Specifically, the end of the second main body portion FF91 near the pressing member is provided with a first protrusion FF911 and a second protrusion FF912, and the first protrusion FF911 and the second protrusion FF912 can be used as the positioning structure described above to be cooperatively connected with the printer, and the connection manner thereof may be a clamping connection, an abutting connection, a plugging connection, or the like, which is not limited herein.
When the pressing component is mounted along the guide rails on both sides of the printer, the pressing element FF40 abuts against the driving unit 1080, and the deformable element FF92 can deform and drive the driving unit 1080 to adjust from an inclined state to a straightening state. Under the deformation force of the deformable member FF92, the pressing member FF40 drives the driving unit 1080 to adjust from the tilted state to the aligned state, and the deformation of the deformable member FF92 is recovered.
In some embodiments, the urging member FF40 includes an abutment portion FF43, an urging portion FF44. The abutting portion FF43 is used to abut against the driving unit protection cover 1081, and the pressing portion FF44 is used to drive the driving unit 1080 to adjust from the tilted state to the aligned state. When the driving unit 1080 is in the aligned state, the rotation axis L1 of the driving unit 1080 is substantially coincident with the central axis L2 of the driving unit protecting cover 1081, i.e., the angle α of the included angle α is zero or close to zero.

Fig. 173 is a schematic diagram illustrating an assembly of a pressing assembly and a process cartridge according to an embodiment of the present application, fig. 174 is another schematic diagram illustrating an assembly of a pressing assembly and a process cartridge according to an embodiment of the present application, and fig. 175 is another schematic diagram illustrating an assembly of a pressing assembly and a process cartridge according to an embodiment of the present application, as shown in fig. 173 to 175, the pressing assembly and the process cartridge according to the present application work cooperatively in a printer. The process cartridge 1 may be a process cartridge having a structure that matches the various embodiments of the pressing assembly FF90 described above. The overall shape of the pressing assembly FF90 is preferably such that it does not interfere with the mounting, dismounting and operation of the process cartridge.
As shown in fig. 173, the driving end of the process cartridge 1 is provided with a first bump FF913 and a second bump FF914, and the second main body portion FF91 is provided with a first protrusion FF911 and a second protrusion FF912 at an end thereof near the pressing member FF 40. The projections and the projections are matingly coupled to each other so that the pressing assembly FF90 can be matingly coupled to the process cartridge 1.
Specifically, as shown in fig. 174 to 175, the first projection FF911 on the second main body portion FF91 is matingly connected with the first projection FF913 on the process cartridge 1, forming a positioning structure; the second boss FF912 on the second main body portion FF91 is matingly connected with the second bump FF914 on the process cartridge 1 to form a positioning structure. The process cartridge 1 is matingly connected to the pressing assembly FF 90.
As shown in fig. 173, the process cartridge provided by the embodiment of the present application may not have any pressing structure such as a cartridge pressing member, and the pressing member FF40 of the pressing assembly FF90 has general applicability in cooperation with the process cartridge 1. Specifically, when the process cartridge 1 in fig. 174 is mounted into the printer, the mounting direction thereof may be the same as the mounting direction of the above-described pressing assembly FF90, i.e., in the direction of arrow M (shown in fig. 69) is fed into the printer.
In some embodiments, the structures included in the pressing element may be preferably integrally formed, so as to improve overall stability.
The following describes the mounting operation of the pressing member FF40 and the process cartridge 1:
as shown in fig. 176, the process cartridge 1 is mounted in a printer (not shown) first, and then the pressing member FF40 is mounted alone in the printer; before the pressing member and the process cartridge are not connected, the driving unit 1080 is supported by the driving head pushing member in the printer and is in an inclined state, i.e., the driving unit 1080 is not aligned by an external force at this time.
The pressing assembly FF90 is continuously mounted along the both side rails of the printer until it is completely mounted, and in the configuration shown in fig. 177, the abutting portion FF43 of the pressing member FF40 is placed on the driving unit protection cover 1081, and the pressing portion FF44 adjusts the driving unit 1080 from the tilted state to the aligned state.
As shown in fig. 176 and 177, the mounted process cartridge 1 is located below the position of the pressing assembly FF90, and at this time, since the thickness of the pressing assembly FF90 of the present embodiment in the direction of the vertical axis above the waste bin of the process cartridge 1 is sufficiently small, the pressing assembly FF90 does not affect the detachment of the process cartridge 1 and its functions, i.e., the process cartridge 1 can be freely mounted or detached independently from the inside of the printer.
Before the process cartridge 1 is mounted to the printer, the pressing assembly FF90 may also be mounted into the printer, so that the abutting portion FF43 of the pressing member FF40 passes through the driving unit protection cover 1081 of the printer, and then the pressing portion FF44 forces the driving unit 1080 to adjust from the tilted state to the aligned state. The process cartridge 1 is then mounted into the printer. At this time, the process cartridge 1 is fitted with the fitting FF90 inside the printer.
Further, the pressing assembly FF90 may be mounted in a developing hopper, which does not include a portion of the photosensitive unit, the charging unit, and the cleaning unit. Or the pressing assembly FF90 is integrally formed with a process cartridge that does not include a photosensitive unit, a charging unit, and a cleaning unit.
Further, when the printer is installed, the printer may be installed first, so that the abutting portion FF43 of the pressing element FF40 of the pressing assembly FF90 passes through the driving unit protecting cover 1081 of the printer first, and then the pressing portion FF44 forces the driving unit 1080 to be aligned first. And then the other part of the printer is filled with the part comprising the photosensitive unit, the charging unit and the cleaning unit.
When the process cartridge 1 is operated, the door of the printer is closed, the driving unit 1080 enters the forced pressing member FF40 to adjust to the aligned state by the external force, and then, as the driving unit 1080 is aligned, the power receiving unit 21 on the process cartridge is gradually engaged with the driving unit 1080, and the power receiving unit 21 of the process cartridge 1 eventually receives the driving force of the driving unit 1080 in a substantially coaxial state. At this time, under the action of the restoring force of the deformable member FF92, the abutting portion FF43 moves to abut against the driving unit protecting cover 1081, so that the pressing portion FF44 no longer contacts the driving unit 1080, and the driving unit 1080 does not rub or even interfere with the pressing member DD40 during the rotation operation, and is in the second state of the pressing member DD40, so that the subsequent normal printing operation can be performed.

The present embodiment provides a process cartridge 1 mounting method, as shown in fig. 188 and 178 a-187, the process cartridge 1 mounting method including the steps of:
step S1: the powder cartridge 11 is loaded inside the electronic imaging device 100;
step S2: the pressing unit 40 of the powder box 11 applies a force to the driving unit 1080 to force the driving unit 1080 to adjust from an inclined state to a set state;
step S3: filling the waste powder box 12 into the powder box 11, and forcing the driving unit 1080 to be in contact fit with the power receiving unit 21; the installation position of the powder box 11 is located at the lower side of the installation position of the waste powder box 12.
Specifically, as shown in fig. 188 and 178 a-187, when the user installs the powder cartridge 11 inside the electronic imaging device along the installation direction of the process cartridge 1 through the installation rail GG50 provided on the inner wall of the electronic imaging device by the second handle GG270 provided on the powder cartridge 11, the first positioning portion GG251 and the second positioning portion GG252 provided on the first cartridge wall GG210 and the second cartridge wall 220 of the powder cartridge 11 are respectively in contact with the installation rail GG50 on both sides of the inner side wall of the electronic imaging device, and the first positioning portion GG251 and the second positioning portion GG252 which force the powder cartridge 11 to pass through are forced to slide along the installation rail GG50 toward the designated installation position in the electronic imaging device due to the thrust from the user in the installation direction of the process cartridge 1, the user continues to apply thrust to the powder cartridge 11 along the installation direction of the process cartridge 1, so that the pressing unit 40 starts to abut against the driving unit GG314 and the driving unit GG320 through the pressing portion GG314 provided on the pressing portion GG310 in the process cartridge 11 continues to move toward the designated installation position of the printer, so that the pressing unit 1080 does not deform the driving unit 313 and deforms towards the driving unit 313; since the force is greater than the elastic force provided by the spring connected to one end of the driving unit pushing member 1090, the driving unit pushing member 1090 cannot be kept at the original position and gradually pushed down, and at this time, the driving unit 1080 also gradually falls down toward the axis direction close to the driving unit protecting cover (blocking wall) 1081 along the gravity direction. When the powder box 11 is pushed to the specified mounting position, the pressing portion GG314 of the pressing member GG310 is completely abutted against the driving unit 1080, and the force applied thereto is maximum, the deformable member GG320 gradually resumes its deformation, and at this time, the driving unit pushing member 1090 is completely pressed down until the axis of the driving unit 1080 can completely coincide with the axis of the driving unit protecting cover (blocking wall) 1081, and the driving unit 1080 is adjusted from the tilted state to the aligned state.
The user installs the waste powder box 12 inside the powder box 11 along the installation direction of the processing box 1 through the first handle GG140 arranged on the waste powder box 12 and the first installation slideway GG231 and the second installation slideway GG232 arranged on the inner side wall of the powder box 11, and the pressing unit 40 arranged on the powder box 11 completely aligns the driving unit 1080, so the power receiving unit 21 can directly complete contact engagement with the driving unit 1080.
When the driving unit 1080 is completely engaged with the power receiving unit 21, that is, when the rotation axis L1 of the driving unit 1080 is substantially coincident with the central axis L2 of the driving unit protecting cover (blocking wall) 1081, one end of the pressing portion GG314 of the pressing member GG310 abuts against the driving unit protecting cover (blocking wall) 1081, so that the pressing portion GG314 is no longer in contact with the driving unit 1080, and friction or even interference is not generated between the driving unit 1080 and the pressing member GG310 during rotation operation, so that the rotation operation of the driving unit 1080 is not affected, and the pressing unit 40 is not damaged.
Further, when the door of the electronic imaging device 100 is closed and the process cartridge 1 is in the working state, the driving unit 1080 is in the aligned state due to the external force of the pressing unit 40, so as to achieve the contact engagement between the driving unit 1080 and the power receiving unit 21, the power receiving unit 21 provided on the waste powder cartridge 12 will eventually receive the driving force of the driving unit 1080 in a substantially coaxial state, and the other gear portion provided on the driving unit 1080 is engaged with the developing roller gear 31. At this time, the deformable member GG320 recovers the elastic deformation, so that one side of the pressing portion GG314 of the pressing member GG310 is forced to move to abut against the driving unit protecting cover (blocking wall) 1081, so that the pressing portion GG314 is no longer in contact with the driving unit 1080, and the driving unit 1080 does not generate friction or even interference with the pressing member GG310 during the rotation operation, so that the subsequent normal printing operation can be performed.

When the process cartridge 1 is pushed to the prescribed mounting position, the pressing portion OO313 of the pressing member OO310 is brought into full abutment with the driving unit 1080, and the force applied thereto is maximized, at which time the driving unit pusher 1090 is fully depressed, the driving unit 1080 falls down in the gravitational direction due to the loss of support, and the driving unit 1080 is adjusted from the tilted state to the aligned state.
In the process of loading the waste toner box 12 from the passage opening of the printer to the corresponding position on the toner box 11 by holding the first handle OO150 provided on the waste toner box 12 by the user, through the guide unit OO620 having an elongated size, the waste toner box 12 is rollingly moved along the first mounting slide OO621 and the second mounting slide OO622 provided on the second box body wall OO240 of the first box body wall OO230 of the toner box 11 by the first mounting portion OO611 and the second mounting portion OO612 provided on the first side wall OO120 and the second side wall OO130 thereof, respectively, in the process cartridge 1 mounting direction into the designated position in the electronic imaging device 100, and the two second urging portions OO420 are also rollingly moved along the first mounting slide OO621 and the second mounting slide OO622, respectively.

Further, as shown in fig. 213, 220 and 221, in the process of assembling the waste toner box 12 and the toner box 11, the two pushing units OO900 provided on the waste toner box 12 are initially contacted with the two abutting portions OO411 provided on the toner box 11, the abutting portions OO411 gradually apply a force to the waste toner box 12 in a direction approaching the developing roller 30 through the pushing units OO900, so as to force the waste toner box 12 to move in a direction approaching the developing roller 30, at this time, the elastic members OO920 provided in the pushing units OO900 gradually start to deform, and the moving portions OO930 in the pushing units OO900 move in a direction perpendicular to the photosensitive drum axis direction accommodating cavities OO912 in a direction away from the first surface portions OO210 of the toner box 11. When the waste toner box 12 continues to be loaded into the designated position of the electronic imaging device 100 in the mounting direction of the process cartridge 1 (i.e., the designated mounting position on the toner box 11), the positioning block OO124 provided on the waste toner box 12 abuts against the positioning portion (not shown in the drawing) provided in the electronic imaging device 100, the two urging units OO900 are brought into full contact with the two abutting portions OO411, the abutting portions OO411 apply an urging force to the waste toner box 12 in the direction F1 through the two urging units OO900 (as shown in fig. 218 and 219), the two second urging portions OO420 abut against the two flange structures OO510 provided on the upper rails of the first mounting rail OO621 and the upper rails of the second mounting rail OO622, so that the second urging portions OO420 surround the axis thereof, and at the same time, under the support of the mounting units OO610 and the guide units OO620, the two flange structures OO510 provided on the waste toner box 12 roll, even if the waste toner box 12 is brought into contact with the developing roller 30 in the direction of the urging direction of the developing roller 20 with the abutment position of the abutment roller 20 (as shown in fig. 20 and the direction of rotation of the urging roller 219).
When the driving unit 1080 is completely engaged with the power receiving unit 21, that is, when the rotation axis L1 of the driving unit 1080 is substantially coincident with the central axis L2 of the blocking wall, one end of the pressing portion OO313 of the pressing OO310 abuts against the driving unit protecting cover (blocking wall) 1081, so that the pressing OO310 is no longer in contact with the driving unit 1080, friction or even interference between the driving unit 1080 and the pressing OO310 is not generated during rotation operation, the rotation operation of the driving unit 1080 is not affected, and the pressing unit 40 is not damaged.

At this time, the deformable member OO320 is elastically deformed, so that the pressing portion OO313 of the pressing member OO310 is forced to move to abut against the driving unit protection cover (blocking wall) 1081, so that the pressing portion OO313 is no longer in contact with the driving unit 1080, and the driving unit 1080 does not rub or even interfere with the pressing member OO310 during rotation operation, so that a subsequent normal printing operation can be performed.
The pressing member OO310 provided in this embodiment is preferably configured to have a structure that does not interfere with the mounting, dismounting, and operation of the process cartridge 1, and the pressing member OO310 and the fixing portion 260 may be plastic members or metal members or the like, and the material of the pressing member OO310 and the fixing portion 260 provided in this embodiment is not limited as long as the mounting thereof and the deformation and recovery of the pressing member OO310 and the deformable member OO320 are not affected. And is preferably constructed as an integral piece for each of the components included in the pressing unit 40 described above.
However, the deformation of the deformable member OO320 is not limited thereto, and instead of using its own elastic force, the pressing member OO310 may be a deformable member instead of the deformable member OO320, and the pressing member OO310 may be a steel sheet with a certain flexible force (capable of pushing the driving unit 1080 to align).

As shown in fig. 183-187 and 220-223, when the powder cartridge 11 is transferred into the electronic imaging device 100, the driving unit 1080 provided in the electronic imaging device 100 is aligned by the pressing unit 40 provided on the powder cartridge 11. In the process of assembling the waste powder box 12 and the powder box 11, two pushing units PP900 arranged on the waste powder box 12 are initially contacted with two abutting positions PP412, the two abutting positions PP412 gradually apply force towards the F1 direction to the waste powder box 12 through the pushing units PP900, the waste powder box 12 is forced to move towards the direction close to the developing roller 30, at the moment, an elastic piece PP920 arranged in the pushing units PP900 is gradually deformed, and a moving part PP930 in the pushing units PP900 moves towards the direction away from a first surface part PP210 of the powder box 11 in the direction perpendicular to the axis of the photosensitive drum, wherein an opening PP9121 is arranged in a containing cavity PP 912. When the waste toner box 12 is continuously loaded into the designated position of the electronic imaging device 100 along the mounting direction of the process cartridge 1 (i.e., the designated mounting position on the toner box 11), the positioning block PP124 provided on the waste toner box 12 abuts against the positioning portion (not shown in the drawing) provided in the electronic imaging device 100, the two pushing units PP900 are completely contacted with the two abutting positions PP412, while the two abutting positions PP412 continuously apply a pushing force (as shown in fig. 220 and 221) to the waste toner box 12 in the direction F1 through the pushing units PP900, the two flange structures PP510 abut against the two second pushing force applying portions PP420, so that the second pushing force applying portions PP420 surround the axis thereof, and simultaneously, under the support of the mounting units PP610 and the guiding units PP620, the two flange structures PP510 provided on the waste toner box 12 roll, even if the waste toner box 12 rotates with the abutting positions as rotation fulcra in the direction approaching the developing roller 30 under the pushing force, and the photosensitive drum 20 is forced to contact with the developing roller 30 in the direction F2 (as shown in fig. 220 and 221).
The operation principle of the pushing unit PP900, the pushing unit 40, and the process cartridge 1 structure related to the present embodiment, and the driving unit 1080 provided in the electronic imaging device 100 being forced to be in contact with and engaged with or disengaged from the power receiving unit 21 by the pushing unit 40 is forty-four the same as that of the embodiment, and will not be repeated here.
It should be noted that, in the technical solutions provided by the forty-second embodiment and the forty-third embodiment, the at least one pushing unit disposed on the waste powder box is configured to act on the waste powder box by the pushing unit when the waste powder box is independently placed in a powder box state, so that the second pushing acting portion on the waste powder box surrounds the axis thereof, and at the same time, the second pushing acting portion rolls at the matching position disposed on the waste powder box under the support of the mounting unit disposed on the waste powder box and the guide unit disposed on the powder box, so that the photosensitive drum moves near the developing roller direction, thereby improving the printing quality of the electronic imaging device 100. The forced pushing unit has the advantages of simplifying the mechanical structure and avoiding the damage of parts. In addition, in the technical scheme provided by the forty-second embodiment and the forty-third embodiment, as the waste powder box and the powder box are assembled in a detachable mode, the structural interference phenomenon caused by the contact and engagement of the power receiving unit and the driving unit can be effectively avoided; and thus causes a printing problem due to poor mounting.

The power receiving unit 21 is drivingly connected to the driving unit 1080, and in the present embodiment, the power receiving unit 21 is engaged with the driving unit 1080 to receive the driving force of the driving unit 1080.
Specifically, an end cap or a bracket is provided at an end of the case 10, and the bracket may be a photosensitive drum frame. Taking a bracket as an example below, the bracket 11 includes a first fixing post 111 and a through hole 112, the power receiving unit 21 is fixed to the bracket 11 through the through hole 112 and exposed to the outside of the through hole 112 to receive a driving force of a driving unit (i.e., driving unit) 1080 of an electrophotographic apparatus (not shown in the drawings), and the first fixing post 111 is disposed above and/or in front of the power receiving unit 21 with respect to an axial direction of the photosensitive drum 20.

The pressing member 40 is detachably mounted in the electronic imaging device, and can be used alone in the electronic imaging device or can work in the electronic imaging device in cooperation with process cartridges of different structures. Specifically, the pressing member 10 is disposed at the same end of the case 10 as the power receiving unit 21, and is configured to press the driving unit 1080, so that the driving unit 1080 is adjusted from an inclined state to an aligned state, and a distance between the pressing member 40 and an axis of the photosensitive drum 20 does not change during engagement of the power receiving unit 21 with the driving unit 1080.
In some embodiments, the urging member 40 is detachably mounted on the first fixing post 111 of the bracket 11.
Optionally, the pressing member 40 is a roller, and a rubber coating is disposed on an outer surface of the roller, so as to avoid abrasion of the driving unit caused by structural interference when the pressing member contacts with the driving unit 1080.
As shown in fig. 225 to 227, in the present embodiment, when the process cartridge 1 is mounted in the electronic imaging device 100 along the Y1 direction during the process of the contact engagement of the power receiving unit 21 of the process cartridge 1 with the driving unit 1080 (i.e., the printer driving head) of the electronic imaging device 100, the pressing member 40 mounted on the frame 11 gradually approaches the driving unit 1080 along with the movement of the process cartridge 1, when the pressing member 40 contacts the driving unit 1080 to form structural interference, the pressing member 40 applies a pressing force F to the driving unit 1080, the driving unit 1080 moves along the direction approaching the power receiving unit 21 after receiving the pressing force, and the pressing member 40 is rotated after the driving unit 1080 contacts the pressing member 40, and because the pressing member 40 is fixedly mounted on the frame 11, the pressing member 40 remains parallel to the axis direction of the photosensitive drum 20 all the time during the process of the engagement of the power receiving unit 21 with the driving unit 1080, i.e., the distance between the pressing member 40 and the axis of the photosensitive drum 20 does not change. With the process cartridge 1 mounted in place, the driving unit 1080 is moved from the initial position to a position parallel to the axial direction of the support 1085, and the final driving unit 1080 is successfully engaged with the power receiving unit 21, so that the driving unit 1080 transmits driving force to the power receiving unit 21, thereby driving the photosensitive drum 20 to rotate.
According to the technical scheme, the pressing piece 40 is arranged on the processing box 1, so that the contact and engagement process of the power receiving unit 21 and the driving unit 1080 is smoother, the contact and engagement time of the power receiving unit 21 and the driving unit 1080 is greatly saved, and the working efficiency of the processing box 1 is improved.

In this embodiment, another process cartridge 1 is provided, and the unspecified parts are the same as those of the process cartridge 1 in the above-described embodiment. This embodiment differs from the above-described embodiment in that: the pressing member of the process cartridge in this embodiment is a retractable member.
As shown in fig. 228 and 229, the end of the process cartridge 1 is provided with a pressing member 40. The pressing member 40 is detachably attached to the process cartridge 1.
Specifically, the process cartridge 1 further includes a first elastic member RR60, and the pressing member 40 is connected to an end portion of the cartridge body 10 via the first elastic member RR60, so that the pressing member 40 can move relative to the cartridge body 10 in a direction parallel or substantially parallel to the axial direction of the photosensitive drum 20, and press the driving unit 1080.
In the embodiment, the pressing member 40 includes a rod coaxially disposed with the photosensitive drum 20 and a protrusion RR41 bent and extended from one end of the rod. The rod body is provided with the first elastic member RR60, and the first elastic member RR60 may be a spring, a torsion spring, a magnet, an elastic sponge, or other elastic members, which are not limited herein. In this embodiment, the first elastic member RR60 is a spring, and the spring is sleeved on the rod body.
The end of the rod body near the power receiving unit 21 is further provided with the protrusion RR41, and the protrusion RR41 is used for pressing the driving unit 1080, so that the driving unit 1080 is coaxially engaged with the power receiving unit 21 or substantially coaxially engaged to transmit power.
When the first elastic member RR60 is in a compressed state, the pressing member 40 can move axially along the length direction of the process cartridge 1 or the photosensitive drum 20, so that the pressing member 40 is away from the driving unit 1080. When the first elastic member RR60 is in the relaxed state, the pressing member 40 can move axially along the length direction of the process cartridge 1 or the photosensitive drum 20, so that the pressing member 40 approaches the driving unit 1080 and drives the driving unit 1080 to press down.
The pressing member 40 may move in the longitudinal direction of the process cartridge 1 or the axial direction of the photosensitive drum 20 and press the driving unit 1080 until the power is transmitted in coaxial engagement or substantially coaxial engagement with the power receiving unit 21 during or after the process cartridge 1 is mounted into place in the electrophotographic apparatus 100.

The process cartridge provided in this embodiment is the same in structure as the process cartridge in forty-four and forty-five embodiments. This embodiment differs from forty-four embodiments and forty-five embodiments in that:

As shown in fig. 230 to 231, the process cartridge further includes a moving positioning member SS50 provided at an end of the cartridge body 10, the moving positioning member SS50 being located at the same end of the cartridge body 10 as the power receiving unit 21.
Specifically, the end cover SS11 of the process cartridge is provided with a chute SS15, and the chute SS15 may be a rectangular chute or a circular chute, or a chute with other regular or irregular structure, which is not limited herein. The moving positioner SS50 is installed in the chute SS15, and the moving positioner SS50 is movable along the chute SS15 with respect to the end cap SS11 of the process cartridge 1.
As shown in fig. 231, when the process cartridge 1 is mounted into the electronic imaging device 100 along the mounting direction by the mounting rail GG50 on the inner side of the electronic imaging device 100, the movement positioning member SS50 is supported by the mounting rail GG50 on the inner side of the electronic imaging device 100 and moves forward along the mounting rail GG 50. Since the movable positioning member SS50 is movable relative to the end cap SS11 of the process cartridge 1, the cartridge body 10 of the process cartridge 1 can be moved to a certain extent relative to the mounting rail GG50 of the electronic imaging device 100 during the mounting process of the process cartridge 1, and the pressing member 40 located at the end of the cartridge body 10 can also be moved to a certain extent (at least up and down movement can be realized) relative to the driving unit 1080 inside the electronic imaging device 100 or the mounting rail GG50 of the electronic imaging device 100 along with the entire movement of the cartridge body 10, and by this movement, the pressing member 40 can be moved upward to a certain extent relative to the driving unit 1080. The process cartridge 1 is mounted in place and then moves downward to drive the driving unit 1080 downward until it is engaged with the power receiving unit 21 substantially coaxially to transmit power.
In this embodiment, due to the arrangement of the movable positioning member SS50, the movable positioning member SS50 can move along the chute SS15 relative to the end cover SS11 and drive the movable pressing member 40 disposed at the end of the case 10 to move relative to the process cartridge, i.e. the movable pressing member 40 can obtain a certain movement amount, so that the movable pressing member mounted on the process cartridge can more easily press the driving unit 1080 to avoid interference.
In addition, the forty-four embodiment, the forty-five embodiment and the forty-six embodiment described above may be used in combination, for example, the moving positioning member SS50 of the forty-five embodiment is applied to the processing box 1 of the forty-four embodiment and the forty-five embodiment, and functions are added to make it easier to achieve the engagement between the power receiving unit 21 and the driving unit 1080, and the solutions of the above embodiments are not mutually exclusive.
Examples forty-seven
In this embodiment, another process cartridge is provided, and the non-illustrated portions are the same as those of the above embodiments, and are not described here again. This embodiment differs from the above-described embodiment in that:
as shown in fig. 232 and 233, the process cartridge 1 provided in this embodiment further includes a telescoping mechanism UU70, and the power receiving unit 21 is connected to one end of the photosensitive drum via the telescoping mechanism UU 70.
Specifically, the telescoping mechanism UU70 is located at an end of the photosensitive drum 20 for controlling movement of the power receiving unit 21 in the axial direction of the photosensitive drum 20. Optionally, the telescoping mechanism UU70 is an elastic member, which may be a spring, a magnet, an elastic sponge, or other elastic components, which is not limited herein.
In this embodiment, the elastic member is a spring, and the end of the photosensitive drum 20 is provided with a groove 20a, and the spring is accommodated in the end groove 20a of the photosensitive drum 20.
Further, the process cartridge 1 further includes a pressing member 40, where the pressing member 40 is sleeved on the outer side of the power receiving unit 21 away from the UU70 of the telescopic mechanism, and the pressing member 40 can rotate coaxially with the photosensitive drum 20, so that the power receiving unit 21 and the pressing member 40 can move along the axial direction of the photosensitive drum 20. In this embodiment, the pressing member 40 is a rotatable sleeve, which may be hollow cylindrical, and the power receiving unit 21 is accommodated in the sleeve and is movable along the sleeve.
Specifically, one end of the telescoping mechanism UU70 (elastic member) abuts against the bottom of the groove 20a, and the other end of the telescoping mechanism UU70 (elastic member) abuts against the power receiving unit 21.
When the process cartridge 1 is not mounted in the electronic imaging device 100, as shown in fig. 232, the power receiving unit 21 can resist the elastic force of the telescoping mechanism UU70 by the frictional force between the power receiving unit 21 and the pressing member 40, and is retracted to be accommodated in the pressing member 40.
When the process cartridge 1 is mounted in the electronic imaging device 100, the driving unit 1080 is supported by a driving head pusher (not shown) in the electronic imaging device and is in an inclined state. That is, the axis of the driving unit 1080 is not parallel to the axis of the photosensitive drum 20, and since the pressing member 40 is sleeved outside the power receiving unit 21, the pressing member 40 and the driving unit 1080 form structural interference, and at this time, the driving unit 1080 starts to rotate and drives the pressing member 40 to rotate.
As shown in fig. 233, in the process of engagement of the power receiving unit 21 with the driving unit 1080, centrifugal force generated by rotation of the pressing member 40 causes the driving unit 1080 to gradually move from the original inclined state to a position where the axis of the driving unit 1080 coincides with the axis of the photosensitive drum 20, at this time, the driving unit 1080 is coaxial with the photosensitive drum 20, after centrifugal rotation of the pressing member 40, friction force between the power receiving unit 21 and the pressing member 40 decreases, the power receiving unit 21 is driven by elastic force of the telescopic mechanism UU70 to move in the direction approaching the driving unit 1080 along the axial direction of the photosensitive drum 20, and by this movement of the power receiving unit 21, the power receiving unit 21 protrudes from the pressing member 40 until it engages with the driving unit 1080, and power transmission between the driving unit 1080 and the photosensitive drum 20 is achieved.
The driving unit 1080 moves toward the printer driving head 1080 along the axial direction of the photosensitive drum 20 by the elastic force of the telescopic mechanism UU70, and by this movement of the photosensitive drum power receiving head 21, the photosensitive drum power receiving head 21 protrudes from the pressing member T40 toward the printer driving head 1080, thereby successfully engaging with the printer driving head 1080, and realizing power transmission between the printer driving head 1080 and the photosensitive drum 20.

In the process of continuing to apply a pushing force to the process cartridge 1 in the mounting direction of the process cartridge 1, so that the process cartridge 1 continues to move to the designated mounting position of the electronic imaging device 100, the limiting portion WW20 applies a supporting force to the supporting member XX310 in the mounting reverse direction of the process cartridge 1, the second side wall WW112 of the end cover WW11 is in contact with the abutment portion XX3211 of the abutment member XX321, so that a pushing force in the mounting direction of the process cartridge 1 is applied to the abutment portion XX3211, the second elastic member XX370 is deformed due to being pressed, and simultaneously the first connecting member XX322 is twisted in a direction approaching the second side wall WW112 with respect to the second movable member XX360 under the driving of the abutment member XX321, and further drives the second connecting member XX323 to move in the mounting reverse direction approaching the second side wall 112 in the mounting reverse direction of the process cartridge 1, and simultaneously drives the urging member XX330 to move in the mounting reverse direction of the driving unit (blocking wall) 1081 toward the process cartridge 1 in the direction in advance to come into contact with the driving unit member 1090.
When the process cartridge 1 is mounted at a predetermined mounting position in the electrophotographic apparatus 100, the pressing force of the stopper WW20 to the support member XX310 in the mounting reverse direction of the process cartridge 1 is maximized, the deformation amount of the second elastic member XX370 is maximized, the first connecting member XX322 is moved closer to the driving unit pushing member 1090 due to the continuously receiving force applied by the second connecting member XX323 in the mounting reverse direction of the process cartridge 1 to the end portion of the second connecting member XX323 in contact with the second side wall WW112, and the urging member XX330 is urged to move closer to the driving unit pushing member 1090 due to the continuously receiving force applied by the second connecting member XX323 in the mounting reverse direction of the process cartridge 1, and gradually applies downward pressure to the driving unit pushing member 1090 to push down the driving unit pushing member 0 at this time, and simultaneously, the driving unit is brought into contact with the receiving unit 10921 due to the falling support force due to the torsion of the second connecting member XX323 in the mounting reverse direction of the process cartridge 1, and the developing roller 1080 is brought into engagement with the receiving unit 1080 and the developing roller 20 is completed.
Further, to ensure that the power receiving unit 21 and the driving unit 1080 can be accurately engaged, as shown in fig. 248, the process cartridge further includes a locking member XX600, the locking member XX600 is disposed at a position close to the cartridge body 10 and close to the photosensitive drum 20, a curved portion XX610 is disposed on the locking member XX600, and when the driving unit 1080 is connected with the power receiving unit 21, a driving device (not shown in the drawing) of the locking member XX600 drives the locking member XX600 to horizontally move towards the direction of the driving unit 1080, and the curved portion XX610 abuts against the driving unit 1080, so as to lock the driving unit 1080.
As shown in fig. 250 to 251, when it is necessary to remove the process cartridge 1 from the electronic imaging device 100, a lock driving device (not shown) drives the lock XX600 to move horizontally in a direction away from the driving unit 1080, at which time the curved portion XX610 is out of abutment with the driving unit 1080, and the driving unit 1080 is unlocked.
In the process of pulling out the process cartridge 1 through the rails GG50 provided on the inner side wall of the electronic imaging device 100 along the opposite direction of the installation of the process cartridge 1 by the handle XX700 provided on the process cartridge 1, the supporting member XX310 gradually gets out of contact with the limit part WW20, the extrusion force applied by the limit part WW20 to the supporting member XX310 along the opposite direction of the installation of the process cartridge 1 gradually decreases, and since the elastic member XX350 needs to recover elastic deformation, elastic force is applied to the first connecting member XX322 to force the first connecting member XX322 to twist between the two connecting arms XX313 symmetrically arranged up and down relative to the second movable member XX360 in the direction approaching the inner wall XX312 and drive the second connecting member XX323 to move along the opposite direction of the installation of the process cartridge 1 in the direction approaching the inner wall XX312 away from the second side wall 112, the second connector XX323 and the second side wall WW112 are gradually separated from contact, and meanwhile the force application member XX330 is driven to move along the inner wall of the driving unit protection cover (blocking wall) 1081 towards the mounting direction of the processing box 1 and further gradually separate from contact with the driving unit pushing member 1090, so that the acting force applied by the force application member XX330 to the driving unit pushing member 1090 is gradually reduced, the driving unit pushing member 1090 moves towards the radial direction of the driving unit 1080 reversely to contact with the driving unit 1080 under the resilience force of a spring, and applies supporting force in the radial direction to the driving unit 1080, so that the driving unit 1080 is forced to incline relative to the axial direction of the driving unit protection cover (blocking wall) 1081, and the driving unit 1080 is separated from engagement with the power receiving unit 21, and meanwhile, the developing roller 30 is also separated from contact with a gear.
After the support member XX310 is completely out of contact with the limit portion WW20, the second elastic member XX370 is completely restored to its deformed state and forces the first side edge XX3221 of the first connecting member XX322 opposite to the second side wall WW112 to be parallel to and spaced apart from each other in the axial direction of the developing roller 30, and the second side edge of the first connecting member XX322 opposite to the inner wall of the end cap WW11 to be parallel to and spaced apart from each other in the axial direction of the developing roller 30. The user holds the handle WW700 to completely remove the process cartridge 1 from the electronic imaging device 100.

Alternatively, the third face YY1033 may be a curved face or a straight face perpendicular to the first face YY1031 and the second face YY 1032. When the first movable member YY103 is in the first position, the first face YY1031, the second face YY1032, and the third face YY1033 are all away from the right side wall YY102, i.e., exposed to the outside, so that the mounting of the incompatible process cartridge can be blocked.
A biasing member for maintaining the position of the first movable member YY103 is also provided on one side of the first movable member YY 103. Illustratively, the biasing member may be a torsion spring with a free end thereof abutting against a rear side of the blocking portion YY1030 of the first movable member YY103, for example, abutting against the second face YY1032, to maintain the first movable member YY103 in the first position when not subjected to an external force.

As the process cartridge 1 moves along the guide rail, the escape portion YY53 escapes from the first movable member YY103, the second urging portion YY52 has a certain guiding function, the second urging portion YY52 abuts against the third face YY1033 of the first movable member YY103 to further urge the first movable member YY103 to rotate toward the second position, the first movable member YY103 is rotated from the first position to the second position, the end face YY13 of the first end cap YY11 abuts against the first movable member YY103, and interference between the protruding portion YY14 of the first end cap YY11 or the protruding portion YY14 of the waste toner cartridge 12 and the first movable member YY103 is avoided, and the first movable member YY103 is guided to the end face YY13 of the process cartridge 1, so that the process cartridge 1 is mounted in place. The process of removing the process cartridge 1 may be such that the first movable member YY103 is returned from the second position to the first position by the elastic deformation force of the biasing member, contrary to the process of mounting the process cartridge 1 described above.
Alternatively, the first pressing surface YY51 and the second pressing surface YY52 may be provided as curved surfaces according to appropriate adjustment. Alternatively, the urging member YY5 may be integrally formed with the first end cap YY11 or the waste toner box 12, or may be provided separately from the waste toner box 12.
By providing the urging member in cooperation with the first movable member, the process cartridge of the present application can be applied to various electronic image forming apparatuses, which is advantageous in the versatility of the process cartridge.
