Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

referring to fig. 1 and fig. 2, the present embodiment relates to a detection mechanism 100, which includes a detection assembly 1 and a driving assembly 2. The path of movement of the detector assembly 1 comprises a first path a. The path of movement of the drive assembly 2 comprises a second path B. The first path a and the second path B may include an intersection. The first path A comprises a first position and a second position. Under predetermined conditions, the driving assembly 2 generates driving force at least once; the driving force pushes the detecting component 1 to move from the first position to the second position. The detection mechanism may be for an imaging cartridge for detecting whether the imaging cartridge is a new imaging cartridge.

Preferably, when the driving assembly 2 is at the starting position, the detection mechanism does not perform the detection operation, and may be in an initial state. When the driving assembly is located at the end position, the detection mechanism completes the detection operation, which can be in a detection completion state. When the driving assembly 2 moves from the starting position to the end position, the detection mechanism can perform a detection process in which the detection mechanism is in a detection state. The start and end positions may be located on the second path B.

As another preferred embodiment, in order to improve the accuracy of detection, the first path a intersects the second path B. The included angle formed by the intersection of the first path a and the second path B is less than 90 °, and the included angle less than 90 ° may be an included angle formed by a direction from the first position to the second position and a direction from the end position to the start position.

The predetermined conditions are: the detection mechanism is in the process of switching from the initial state to the detection state, or in the process of switching from the initial state to the detection completion state, or in the process of driving the detection assembly to move from the first position to the second position by the driving assembly. The driving assembly 2 can drive the detection assembly 1 to move in the first path A when moving in the second path B. When the detection assembly 1 moves on the first path A, the detection operation is realized. Before the predetermined condition occurs or after the predetermined condition is completed, the driving assembly 2 stops driving the detecting assembly 1 even if the driving assembly 2 moves on the second path B, or the driving assembly 2 generates insufficient driving force to drive the detecting assembly 1 to move on the first path a even if the driving assembly 2 is in contact with the detecting assembly 1. For example, the detecting member 1 may be stationary at a certain position of the first path a before the predetermined condition occurs or after the predetermined condition is completed.

As a preferred embodiment, the detecting component 1 of the detecting mechanism can realize one detecting operation or complete partial actions of one detecting operation when the first path a moves, so that whether the detecting mechanism is installed to detect whether the detecting mechanism is an unused detecting mechanism or a new detecting mechanism. When the detection mechanism is mounted to the image forming cartridge, the image forming cartridge can be detected as a new image forming cartridge. Other information of the cartridge, such as the capacity or model number, may be known from the sensing mechanism during the process of sensing whether it is a new cartridge.

As a preferred embodiment, the detecting assembly 1 comprises a first detecting member 11. When the detecting assembly 1 is at the second position, the first detecting member 11 can be located at the detected position. The first detecting member 11 is used for being detected by other equipment. For example, when the detecting mechanism is mounted in the image forming apparatus, the first detecting member 11 cooperates with the detecting mechanism in the image forming apparatus, and whether the first detecting member 11 has reached the detected position can be detected by the detecting mechanism in the image forming apparatus. For example, the detection mechanism in the image forming apparatus is provided with a detection switch which is triggered when the first detection member 11 indicates that the detected position has been reached. If the detecting mechanism in the image forming apparatus includes a laser detector, the first detecting member 11 will trigger a detecting switch when reaching the detected position, and the signal of the laser detector will change, for example: a change from an ON signal to an OFF signal or a change from an OFF signal to an ON signal is generated. When the detecting assembly 1 is at the first position, the first detecting member 11 is away from the detected position.

The number of the first detecting members 11 is at least one, and when the number of the first detecting members 11 is two or more, the first detecting members 11 are arranged at intervals. Preferably, the first detecting members 11 may be arranged in a row at intervals along the first path a. So that each first detecting member 11 can be detected once during the detection process.

The first detecting member 11 may include a protrusion 11a, and the shape of the protrusion 11a, such as a column, a hook, or a hemisphere, may be set according to actual needs. As another preferred embodiment, the first detecting member 11 may further include a metal sheet (not shown). The metal sheet is mounted on the protrusion 11a, and the metal sheet can be contacted with a detection mechanism in the imaging device to complete detection operation. Of course, the protrusion 11a may also be made of metal.

If the detecting mechanism in the imaging device includes an electric energy detector, the protrusion 11a or the metal sheet of the first detecting member 11 will contact the electric energy detector when reaching the detected position, and the electric energy detector receives the information of the change of the electric energy, thereby achieving the purpose of detection. When the first detecting member is located at the detected position, the driving assembly 2 generates a driving force to the detecting assembly 1, or the driving assembly 2 contacts the detecting assembly 1. When the detecting assembly 1 is at the first position, the first detecting member 11 is away from the detected position.

For better completion of the detection operation, the detection assembly 1 may further comprise a second detection member 12. Under the predetermined condition, the second detection member 12 receives the driving force. The second detecting member 12 can move along the first path a after receiving the driving, so as to move the detecting component 1 from the first position to the second position. The first detecting member 11 may be attached to the second detecting member 12. When the detecting assembly 1 moves from the first position to the second position, the first detecting member 11 can move to the detected position along with the second detecting member 12. The first detecting member 11 may be fixed to the second detecting member 12. The first detecting member 11 is movable with the movement of the second detecting member 12.

The drive assembly 2 comprises a first drive portion 21; under predetermined conditions, the first driving portion 21 comes into contact with the detecting member 1 at least once and generates a driving force. The number of the first driving parts 21 may be one or more. The specific data can be set according to actual needs. For example, when it is necessary to detect other information in addition to the requirement of detecting whether or not it is a new product, the number of the first driving portions 21 may be increased. When it is necessary to detect the capacity of the image forming cartridge in addition to whether or not the image forming cartridge is a new one as after the detection mechanism is mounted to the image forming cartridge, it is possible to make a distinction by providing 21 different numbers of first driving portions. In addition, different numbers of the first driving portions 21 may be used to distinguish between different versions or different models of the image forming cartridges.

When the number of the first driving parts 21 is more than one, each of the first driving parts 21 drives the primary detecting member 1 when the driving member 2 moves on the second path, so that the first detecting part 11 enters the detected position a plurality of times. The capacity, version, model, or the like of the image forming cartridge can be distinguished by the number of times the first detection portion 11 enters the detected position. Preferably, each of the first driving portions 21 is disposed at intervals on the second path so as to better drive the detecting assembly 1 to move on the first path.

Preferably, the first driving unit 21 drives the detecting unit 1 to move more preferably. The cross section of the first driving part and the end part detected by the inclined surface is smaller than that of the other parts of the first driving part. For example, referring to fig. 2 or 11, the first driving portion includes a tip portion, which may have a tapered shape or a trapezoidal truncated cone shape. The cross-section is perpendicular to axis L1.

Of course, it is also possible to distinguish the capacity, version, model, or the like of the image forming cartridge according to the time period for which the first detection portion 21 of the detection assembly 1 enters the detected position (refer to fig. 11). For example, the first driving portion 21 may have a long length, and may keep generating the driving force for a certain time to drive the detecting unit 1. For example, the first driving portion 21 is long enough to generate a driving force for driving the detecting member 1 for several seconds, which may be a certain period of time from 1 to 30 seconds. Or the length of the first driving part 21 is greater than or equal to 1 mm and less than or equal to 1/2 or 2/3 of the total length of the driving assembly.

The second detecting member 12 may further include a force receiving portion 121 and a mounting portion 122. The force receiving portion 121 may be in contact with or separated from the first driving portion 21 of the driving assembly 2. Under predetermined conditions, the first driving portion 21 can slide on the force-receiving portion 121, so as to generate a driving force to drive the detecting component 1 to move on the first path a. The force receiving part 121 may include an inclined surface 121 a. The inclined surface 121a allows the driving assembly 2 to better drive the detecting assembly 1 in the first path a. The inclined surface 121a is located on a surface that intersects with the axis L1 of the first driving part 21 of the driving assembly 2 and is not perpendicular thereto. Such that the driving force generated by the drive assembly intersects the inclined surface. Preferably, the driving force intersects the inclined surface but is not perpendicular.

The first detector 11 may be attached to the attachment portion 122. The first detecting member 11 and the force-receiving portion 121 may be respectively located on one surface of the mounting portion 122. Preferably, the first detecting member 11 and the force receiving portion 121 are located on different surfaces of the mounting portion 122. So that the driving assembly 2 can drive the detection assembly 1 to move on the first path a when the second path B moves.

Reference is made to fig. 3a-3 d. Fig. 3a shows the detecting assembly 1 in the first position. Fig. 3c shows the detecting assembly 1 in the second position. When the driving member 2 is in contact with the sensing member 1, and the driving member 2 moves toward the end position on the second path B (or moves toward the sensing member 1), the first driving portion 21 pushes the sensing member 1 to move toward the second position. The first driving part 21 may slide on the inclined surface 121a of the force receiving part 121. During the sliding of the first driving portion 21 on the inclined surface 121a, the first detecting member 11 reaches the detected position from the non-detected position. The detected position may have a portion that coincides with the second position or be located between the first position and the second position. When the number of the first detecting members 11 is only one, the detected position may have a portion overlapping with the second position. When the number of the first detecting members 11 is greater than one, each of the first detecting members 11 corresponds to one detected position, and the detected position of one first detecting member 11 may be located between the first position and the second position.

The drive assembly 2 may also include a connecting portion 22. The first driving part 21 may be fixed to the connecting part 22. When the number of the first driving portions 21 is plural, a gap may be formed between the adjacent first driving portions 21. When the driving assembly 2 moves on the second path B, each of the first driving portions 21 drives the detecting assembly 1 to move on the first path a, respectively.

In order to make the space occupied by the detection mechanism sufficiently uniform, the long axis L2 of the mounting portion 122 forms an angle with the extension line of the long axis L3 of the connecting portion 22, and the angle is smaller than 180 °. Preferably, the included angle may be around 90 °, for example between 80 ° and 100 °. This can be achieved by the drive assembly 2 and the detection assembly 1 not being parallel in their movement paths. Thereby realizing that the detection mechanism can better utilize the space.

As another preferred embodiment. The connecting portion 22 may be in the shape of a long strip or an arc, as shown in fig. 12a and 12 b. The arc can better reduce the occupation space of the connecting part and can also realize more detection results.

The drive assembly 2 may further comprise a second drive portion 23. The first driving unit 21 and the second driving unit 23 are fixed to the connecting unit 22. The connection portion 22 may be located between the first driving portion 21 and the second driving portion 23. The second driving portion 23 may serve as a power source for the driving assembly 2. The force applied to the second driving portion 23 can be transmitted to the first driving portion 21 through the connecting portion 22, so that the first driving portion 21 can drive the detecting assembly 1. Of course, at least one of the connection portion 22 and the second driving portion 23 may be omitted. For example, when the connecting portion 22 and the second driving portion 23 are omitted, the first driving portion 21 is directly driven by an external force to move, thereby contacting the detecting unit 1 and generating a driving force.

Preferably, in order for the first driving part 21 to smoothly drive the detecting unit 1, the first driving part 21 includes a convex tooth 21 a. The detection assembly 1 moves from a first position to a second position; the teeth 21a slide on the inclined surfaces 121 a. When the driving assembly 2 moves on the second path B, the driving assembly can drive the convex tooth 21a to move on the second path B, and at this time, the force receiving portion 121 can be pushed by the convex tooth 21a, since the inclined surface 121a intersects with the axis L1 of the convex tooth 21a and is not perpendicular, the convex tooth 21a can slide on the inclined surface 121a, and the detection assembly 1 is pushed to move on the first path a.

Referring to fig. 4 and 5, the preferred embodiment is shown. In order to realize that the detection mechanism can be used repeatedly or meet the preset detection result (such as new and old product detection or product version detection), the detection mechanism can also comprise a first limiting component 3. The first limiting component 3 is positioned on the first path A. At least part of the first limiting component 3 is in contact with the detection component 1. The first limiting component 3 can also be used for limiting the detecting component 1, and limiting the detecting component 1 to move on the first path a.

Referring to fig. 4 and 5, a preferred embodiment is shown. The first position-limiting component 3 is provided with a first position-limiting hole 3a, and the mounting portion 122 of the second detecting member 12 is movably inserted into the first position-limiting hole 3 a. The detection component 1 is inserted into the first limiting hole 3a, and at least part of the detection component 1 is exposed out of the first limiting hole 3 a. At least the first detecting element 11 and a part of the second detecting element 12 are exposed to the first stopper hole 3 a.

When the detecting assembly 1 moves on the first path a, a portion of the mounting portion 122 can move inside the first limiting hole 3a and outside the first limiting hole 3 a. For example, a portion of the mounting portion 122 close to the force-receiving portion 121 may move from inside the first limiting hole to outside the first limiting hole on the first path, or a portion of the mounting portion 122 close to the force-receiving portion 121 may move from outside the first limiting hole to inside the first limiting hole on the first path. The first stopper hole 3a has a diameter larger than the maximum outer diameter of the portion of the mounting portion 122 that is movable inside and outside the first stopper hole 3 a. Thereby allowing the mounting portion 122 to move in the first path a. The mounting portion 122 may also be restrained by the first restraining assembly 3. The first limiting hole 3a may be a circular, rectangular or other polygonal through hole, or an inward concave hole or groove.

Referring to fig. 4 and 5, a preferred embodiment is shown. In order to better guide the movement of the detecting assembly 1 on the first path a. The first position-limiting component 3 may include a first position-limiting portion 31 and a second position-limiting portion 32. The first position-limiting portion 31 is provided with a first position-limiting hole 3 a. The second stopper portion 32 is provided with a second stopper hole 3 b. The second limiting hole 3b is a through hole of a circle, a rectangle or other polygons, or an inward concave hole or groove. The mounting portion 122 may include a first end 122a and a second end 122b, wherein the first end 122a may be movably inserted into the first position-limiting hole 3a, and the second end 122b is inserted into the second position-limiting hole 3 b. Carry on spacingly to the both ends of installation department 122 through first spacing subassembly 3 for the precision that detection component 1 moved in first route A is higher, makes the completion detection achievement that first detection piece 11 can be better.

Referring to fig. 4 and 5, a preferred embodiment is shown. In order to enable the driving assembly 2 to drive the detecting assembly 1 more smoothly, the detecting mechanism of the present embodiment further includes a second limiting assembly 4. The second position-limiting component 4 is located on the second path B. At least part of the second limiting assembly 4 is in contact with the driving assembly 2.

The second position limiting component 4 comprises a second position limiting part 41. The second position-limiting portion 41 is provided with a third position-limiting hole 4 a. Part of the driving component 2 is inserted into the third limiting hole 4 a. Part of the driving element 2 is exposed to the third limiting hole 4 a. The third limiting hole 4a is a through hole of a circle, a rectangle or other polygons, or an inward concave hole or groove.

As a preferred embodiment, a portion of the connecting portion 22 of the driving assembly 2 may be inserted into the third limiting hole 4 a. The connecting portion 22 is at least partially exposed from the third limiting hole 4 a. The connecting portion 22 includes a third end 22a and a fourth end 22 b. The third end 22a is movably inserted into the third limiting hole 4 a. A portion of the third end 22a may move in and out of the third limiting hole 4a during movement of the second path B of the driving assembly 2. At least the fourth end 22b is exposed to the third limiting hole 4 a.

Referring to fig. 6 and 7, as a preferred embodiment, in order to enable the driving assembly 2 to move more precisely on the second path B, the detecting mechanism in this embodiment may further include a transmission assembly 5. The transmission assembly 5 drives the driving assembly 2 to move on the second path B. The transmission assembly 5 may be in contact with or separated from the driving assembly 2 before the sensing assembly 1 completes sensing. Preferably, a portion of the transmission assembly 5 may be in contact with or separated from the second driving portion 23 of the driving assembly 2.

The second driving part 23 may include a plurality of gear teeth 23 a. Before the detection assembly 1 completes the detection, when the transmission assembly 5 moves, the gear teeth 23a may be sequentially pushed, so as to drive the driving assembly 2 to move on the second path B. After the transmission assembly 5 pushes all the gear teeth 23a in sequence, the driving assembly 2 moves from the initial position to the final position on the second path B. The initial position may be: the position of the drive assembly 2 prior to movement of the second path B. The end positions may be: the position in which the drive assembly 2 has moved after the second path B and stopped moving. Referring to fig. 7d, in the end position, the transmission assembly 5 in turn pushes all the gear teeth 23a and the transmission assembly 4 is disengaged from the drive assembly 2.

Preferably, the transmission assembly 5 rotates around its axis L when moving. The drive assembly 2 can be pushed into motion during rotation. The second path of movement of the drive assembly 2 may be linear or arcuate.

Referring to fig. 7a to 7d, as a preferred embodiment, in order to better realize that the transmission assembly 5 drives the driving assembly 2, the transmission assembly 5 includes a rotating portion 51 and a protruding portion 52. The rotating part 51 is fixedly connected with the boss 52. The second driving part 23 may be pushed by the protrusion 52.

As shown in fig. 7a, the protrusion 52 may not drive the driving assembly 2 before the rotating portion of the transmission assembly 5 rotates. When the transmission assembly 5 rotates to the predetermined position, the projection 52 may contact the second driving portion 23 (refer to fig. 7a) and generate a driving force to push the driving assembly to move in the second path (refer to fig. 7b and 7c) when the rotation in the original direction (F1) is continued. When the transmission assembly 5 moves to a certain position (refer to fig. 7b), the driving assembly 2 pushes the detection assembly 1 to move on the first path a. When the driving assembly 2 is driven by the transmission assembly 5, the driving assembly 2 continues to move in the direction F2 on the second path B, and the detecting assembly 1 is further pushed to move towards the second position on the first path. When the driving assembly 2 moves to another position (refer to fig. 7b or fig. 7c), one of the first driving portions 21, which is originally in contact with the driving assembly 2, leaves the boss portion 52. At this time, the first detecting member 11 of the detecting assembly 1 has reached the detected position, and if the driving assembly 2 continues to advance, the first detecting member 11 of the detecting assembly 1 can leave the detected position. When the driving assembly 2 reaches the end position (refer to fig. 7d), the driving assembly 2 and the transmission assembly 5 are always kept in a separated state, even if the transmission assembly 5 keeps rotating, the driving assembly 2 is not driven by the transmission assembly 5, and the detection assembly 1 stops moving relative to the driving assembly 2.

As a preferred embodiment, the transmission assembly 5 and the second driving portion 23 may also be performed by friction. In this embodiment, the projection 52 may be omitted, and the surface contacting the transmission assembly is provided as a friction surface. When the driving assembly 2 reaches the end position, the outer surface of the rotating portion 51 contacts the friction surface of the second driving portion 23, and the driving assembly 2 can be driven by the transmission assembly 5 when the transmission assembly 5 moves by using the friction force between the outer surface of the rotating portion 51 and the friction surface of the second driving portion 23. In the end position, the second drive 23 is disengaged from the transmission assembly 5. When the driving assembly 2 is at the end position, even though the transmission assembly 5 is still moving, the driving assembly 2 is not driven to move on the second path B, so that the detecting assembly 1 stops at a certain position of the first path a, for example, at the first position or at a certain position between the first position and the second position. Furthermore, the effect of driving the driving assembly through the transmission assembly 5 can be achieved by the friction force between the protruding portion 52 and the friction surface of the second driving portion 23.

Referring to fig. 6 and 3a-3d, in order to improve the accuracy of the detection mechanism, a preferred embodiment is shown. The detection mechanism further comprises a reset assembly 6. The reset assembly 6 may be connected to the sensing assembly 1. The reset assembly 6 drives the detection assembly 1 to move from the second position to the first position. The return member 6 may be an elastic member, such as a spring, a torsion spring, or the like. The detection assembly may compress the reset assembly when the detection assembly moves toward the second position. When the driving force for pushing the detecting component 1 to move towards the second position is small enough or cancelled, the resetting component 6 generates a resilience force due to compression, and the detecting component 1 is reset to the first position.

When the position of fig. 3d is reached, the driving force of the driving detecting assembly 1 of the driving assembly 2 becomes weak or disappears, and the detecting assembly 1 is pushed to move towards the first position by the resilience of the resetting assembly 6, so that the first detecting member 11 enters the detected position again.

As a preferred embodiment, if the reset assembly 6 is omitted, a plurality of first detecting members 11 may be provided. Then when the driving component 2 pushes the detecting component 1 to move on the first path a, each first detecting piece 11 can pass through the detected position at least once, and different detecting results can be achieved according to the detected number of the first detecting pieces 11. Each of the inspection components may be inspected once from the beginning of inspection to the completion of inspection. When the driving assembly 2 continues to move forward along the second path B after the driving assembly reaches fig. 3a to fig. 3d, when the second first driving portion 21 reaches the force-receiving portion 121, the driving assembly 2 can drive the detecting assembly 1 to move forward, and the second first detecting member 11 is pushed to pass through to the detected position once.
