The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a developing cartridge 10 in the prior art. The chip holder 170 is detachably mounted on one side of the case 110, and the chip holder 170 includes a holder 173 and a spring 179 coupled to the holder 173. A chip 300 is disposed on the holder 173, the chip 300 including electrical contacts 310. The top of the holding portion 173 is provided with a catching portion 178. The printer includes a fixing portion 227 corresponding to the engaging portion 178 and a probe 221 corresponding to the electrical contact 310.

When the developing cartridge 10 provided with the chip frame 170 is mounted to a printer, the chip frame 170 is mounted with the cartridge body 110 from top to bottom, the spring 179 is contracted by artificial force, a part of the chip frame 170 enters a chip frame mounting area of the printer, at this time, if the artificial force is insufficient, the engaging portion 178 is blocked by the fixing portion 227, wherein the fixing portion 227 protrudes relative to a plane where the probe 221 is located, and then, under the artificial continuous external force application, the engaging portion 178 passes over the fixing portion 227, so that the top of the engaging portion 178 is located below the fixing portion 227, and thus the chip frame 170 can be fixed by the fixing portion 227 and the engaging portion 178. When the engagement portion 178 passes over the fixing portion 227, the fixing portion 227 releases the spring 179 from pressing by the external force applied by the human, and the spring 179 returns to its original state. When the spring 179 returns to its original position, the holding portion 173 and the chip 300 are driven to move toward the position of the probe 221, and finally, the electrical contact 310 and the probe 221 are electrically connected.

In the above-mentioned mounting process, since a large force is required to be manually applied to achieve the operation of the engaging portion 178 crossing the fixing portion 227, if the external force is not sufficiently applied, the chip 300 is not mounted in place, so that the electrical contacts 310 cannot be aligned and electrically connected with the probes 221 precisely, and the chip 300 is not recognized.

The defects existing in the above solutions are the results obtained after the inventors have experimented and studied, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present application for the above problems should be the contributions of the inventors to the present application in the process of the present application.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a developing cartridge 100 according to an embodiment of the present disclosure. The developing cartridge 100 is detachably mounted to a printer. The printer includes a first guide portion 210 and a second guide portion 220, wherein a metal probe 221 is disposed on the second guide portion 220. The developing cartridge 100 includes a cartridge body 110, a supporting shaft 120, and a chip holder 130. The support shaft 120 is disposed on the surface of the case 110 and protrudes relative to the surface of the case 110. The chip frame 130 is rotatably fitted over the support shaft 120. Since the chip holder 130 can rotate, the chip 300 on the chip holder 130 can be driven to move toward the second guiding portion 220 during the rotation process, so as to drive the electrical contact 310 of the chip 300 to rotate to the position of the probe 221 and electrically connect with the probe. The printer may read information from the chip 300 or write information to the chip 300.

Referring to fig. 3, fig. 3 is a partial structural schematic view of the developing cartridge 100 according to the embodiment of the present application. The first guide portion 210, the second guide portion 220 and the support shaft 120 may be located on the same side of the case body 110 so as to mount the chip frame 130, and the chip frame 130 may rotate to bring the electrical contacts 310 of the chip 300 on the chip frame 130 into contact with the probes 221 on the second guide portion 220.

Referring to fig. 2 to 4, fig. 4 is a schematic structural diagram of the chip frame 130 in fig. 2. The chip holder 130 includes a sleeve portion 131, and a holding portion 133 and an abutting portion 135 connected to the sleeve portion 131. The sleeve portion 131 includes a sleeve hole 1312, and the sleeve portion 131 is rotatably fitted over the support shaft 120 through the sleeve hole 1312. The holding portion 133 includes a mounting portion 1334 for mounting the chip 300, and the abutting portion 135 contacts the first guide portion 210 when the developing cartridge 100 is mounted to the printer, and moves the holding portion 133 toward the probe 221 by interaction with the first guide portion 210, so that the electrical contact 310 of the chip 300 on the holding portion 133 contacts the probe 221.

The cartridge 110 may be an elongated housing for accommodating the developer. The support shaft 120 may be disposed at an end of the case 110, and a length extension direction of the support shaft 120 is the same as that of the case 110. The bottom of the cartridge 110 may also be provided with a toner shaft (not shown) to which toner (i.e., developer) may be attached. The inside of the printer has a developing chamber having a length equal to that of the developing cartridge 100, and after the developing cartridge 100 is loaded into the developing chamber, the toner shaft enters the inside of the printer. After the printing program is started, the carbon powder can be finally developed on the printing medium along with the operation of the printing program in the rotation process of the carbon powder shaft.

The printer further includes a receiving space for receiving the supporting shaft 120, the chip holder 130 and/or other components. The first guiding portion 210 is located below the accommodating space, and the first guiding portion 210 is fixed and can be matched with the chip frame 130 sleeved on the supporting shaft 120 to play a role in contacting and supporting or generate an interaction force due to extrusion and abutting of the chip frame 130, so that the chip frame 130 rotates.

The second guide part 220 may be positioned above the first guide part 210 with a certain interval from the support shaft 120 to receive the holder 133 of the chip holder 130, thereby facilitating the rotation of the chip holder 130. The plurality of probes 221 of the second guide part 220 may be spaced apart along the lengthwise extending direction of the cassette body 110 and opposite to the support shaft 120 so that the electrical contacts 310 of the chip 300 on the chip holder 130 disposed on the support shaft 120 are in contact with the probes 221. It is understood that the spacing between the electrical contacts 310 on the chip 300 is the same as the spacing between the corresponding probes 221, and the number of electrical contacts 310 corresponds to the number of probes 221 to ensure the electrical connection of the chip 300 and the probes 221.

The second guide part 220 may further include a fixing plate 223 and at least one sidewall, and the probe 221 is disposed on the fixing plate 223. The side wall is arranged at the edge of the fixing plate 223 and protrudes relative to the plane of the fixing plate 223, that is, the side wall forms an included angle with the plane of the fixing plate 223, so that the probe 221 can be protected, and the probe 221 is prevented from being scratched by other mounting parts to deform or break.

Optionally, the fixing plate 223 is partially provided with a side wall at the edge, and is not provided with a side wall at the other edge. For example, if the fixing plate 223 has a rectangular shape, three sides thereof are provided with side walls, and the remaining side corresponds to the rotation direction of the chip rack 130 and is not provided with side walls. Therefore, the probe 221 can be protected, the chip frame 130 can be conveniently rotated, and meanwhile, the chip frame 130 can be prevented from continuously rotating when the chip frame 130 rotates to a proper position. The side wall for blocking the chip holder 130 from further rotation is the blocking wall 224. The mounting portion 1334 has a size corresponding to that of the second guide portion 220 to ensure contact of the electrical contact 310 with the probe 221.

The probe 221 may be connected to a controller located inside the printer. The controller may be formed of a circuit board. The controller may include a processor (e.g., a CPU) and various memories, and controls various processes executed in the printer by operations of the processor according to an operation program.

In this embodiment, the diameter of the sleeve hole 1312 corresponds to the diameter of the support shaft 120. When the chip holder 130 is mounted on the support shaft 120, since the diameter of the sleeve hole 1312 corresponds to the diameter of the support shaft 120, the sleeve portion 131 is in interference fit with the support shaft 120, so that the chip holder 130 does not freely swing on the support shaft 120 and does not easily fall off the support shaft 120. Further, the length of the supporting shaft 120 may be slightly greater than the length of the sleeve hole 1312 to further ensure the mounting effect of the chip holder 130 on the supporting shaft 120.

As shown in fig. 2 and 4, the abutting portion 135 extends along one side of the sleeve portion 131, and the holding portion 133 extends along the other side of the sleeve portion 131 in a direction approaching the abutting portion 135. Wherein a free end of the abutting portion 135 is opposite to a free end of the holding portion 133.

The abutment 135 may be an arcuate structure to facilitate rotation. The abutment portion 135 extends in a direction away from the socket portion 131, and the thickness of the abutment portion 135 decreases as the distance between the abutment portion 135 and the socket portion 131 increases. This increases the elasticity of the free end of the abutment 135. The above arrangement ensures that the chip holder 130 is rotated by the interaction between the abutting portion 135 and the first guide portion 210.

Further, the abutting portion 135 may be an elastic member, for example, a member made of a rubber material.

Referring to fig. 4 again, the mounting portion 1334 may include a mounting groove 1336, and the mounting groove 1336 is used for accommodating the chip 300. The chip 300 includes a first side on which the electrical contacts 310 are disposed and a second side on which circuit components may be disposed, the second side contacting the bottom of the mounting slot 1336, thereby hiding the circuit components of the second side into the mounting slot 1336. When the chip 300 is mounted in the mounting groove 1336, the second side of the chip 300 faces the opening of the mounting groove 1336, the circuit component first contacts the bottom of the mounting groove 1336, and after the mounting, the first side of the chip 300 exposes a row of electrical contacts 310 to facilitate contact with the probes 221. Alternatively, the chip 300 may be mounted, welded, or otherwise secured in the mounting slot 1336.

Further, in the case where the size of the mounting part 1334 corresponds to the size of the second guide part 220, the size of the mounting groove 1336 may be set to be sufficiently large, thereby making it possible to apply the developing cartridge 100 to various chips 300 having sizes not exceeding the size of the mounting groove 1336.

Further, the mounting groove 1336 is disposed on a side of the mounting portion 1334 facing away from the sleeve portion 131.

Further, the retaining portion 133 includes an extension section 1331 and a mounting section 1332, the mounting section 1332 is connected to the sleeve portion 131 through the extension section 1331, and the mounting section 1334 is disposed at one end of the mounting section 1332 away from the extension section 1331. Optionally, the mounting section 1332 is angled with respect to the extension section 1331. In one embodiment of this embodiment, the holding portion 133 may have an L-shaped structure.

The developing cartridge 100 will be further described with reference to fig. 2.

The length extending direction of the box body 110 is defined as a first direction, and a direction vertically crossing the first direction is defined as a second direction (i.e., a height direction shown in fig. 1). Preferably, the second direction is perpendicular to the first direction, and the second direction corresponds to a direction in which the developing cartridge 100 is inserted into the printer, and further, a direction crossing the first direction and the second direction is referred to as a third direction. Preferably, the third direction is perpendicular to the first direction and the second direction, and horizontally crosses the first direction and vertically crosses the second direction.

The support shaft 120 is disposed on the surface of the case 110 in a first direction. The first guide portion 210 may have a strip-shaped structure, and the length extending direction is parallel to the third direction. The printer is provided with a second guide part 220 facing the support shaft 120 in a third direction, and the second guide part 220 has a height extending direction parallel to the second direction and a length extending direction parallel to the first direction, and the plurality of probes 221 of the second guide part 220 are arranged in a row in the first direction. The second guide part 220 has a top wall (i.e., a blocking wall 224) protruding in a third direction at the top thereof, and side walls protruding in the third direction at both left and right sides thereof to prevent the probe 221 from being damaged by being scratched by other mounting parts. The bottom of the second guide part 220 is not provided with a bottom wall protruding in the third direction, so that the holding part 133 is not blocked when moving from bottom to top in the second direction, and then the holding part 133 can move to a position where the electrical contact 310 corresponds to the probe 221.

As shown in the chip holder 130 of fig. 2, the abutting portion 135 extends in a third direction from the second direction, and an extending end (i.e., a free end) is parallel to the central axis of the sleeve portion 131. Alternatively, the extended end of the abutting portion 135 and the root (i.e., the end of the abutting portion 135 connected to the sleeve portion 131) form an angle smaller than 90 degrees with the center of the sleeve portion 131 as the vertex.

The retaining portion 133 extends in a direction away from the sleeve portion 131 and toward the abutment portion 135. Alternatively, the extending end of the holding portion 133 and the root (i.e., the end of the holding portion 133 connected to the sleeve portion 131) may form an angle smaller than 90 degrees with the center of the sleeve portion 131 as the vertex.

Next, the mounting process of the developing cartridge 100 will be described with reference to fig. 2 to 5.

First, the chip 300 is mounted to the holding portion 133. When the chip 300 is fixed to the holding portion 133, the electrical contact 310 does not protrude from the holding portion 133 due to the presence of the mounting groove 1336, thereby preventing the electrical contact 310 from being scratched and damaged by other components of the printer during the process of mounting the developing cartridge 100 to the printer, and thus preventing the electrical connection between the electrical contact 310 and the probe 221 from being adversely affected.

Next, as shown in fig. 2, the sleeve portion 131 is fitted to the support shaft 120 in a direction in which the holding portion 133 is attached to the second guide portion 220 and the abutting portion 135 is attached to the second guide portion 220. Meanwhile, the end of the free end of the abutting portion 135 is kept parallel to the width direction of the first guide portion 210, and is opposite to the central axis of the sleeve portion 131 in the direction in which the developing cartridge 100 is inserted into the developing cartridge, that is, the straight line on which the end of the free end of the abutting portion 135 is located is parallel to the width direction of the first guide portion 210, and is opposite to the central axis of the sleeve portion 131 in the second direction, thereby allowing the end of the free end of the abutting portion 135 to be entirely in contact with the first guide portion 210. Since the second guide part 220 has a distance from the support shaft 120, the distance can accommodate the holding part 133 without the second guide part 220 contacting the holding part 133 when the chip holder 130 is mounted to the support shaft 120 and is not rotated. When the sleeve portion 131 is fitted on the support shaft 120, the end of the free end of the abutting portion 135 is not parallel to the width direction of the first guide portion 210, and the chip holder 130 is manually adjusted to the end of the free end of the abutting portion 135 to be parallel to the width direction of the first guide portion 210.

As shown in fig. 5, after the chip 300 and the chip frame 130 are mounted, they are inserted into the developing chamber of the printer together with the box 110 from top to bottom along the second direction. Since the developing cartridge 100 has a plurality of toner shafts of different colors and other components at the bottom thereof, the developing cartridge 100 itself has a certain weight. When the developing cartridge 100 is inserted into the developing cartridge, the abutting portion 135 first contacts the first guide portion 210, and meanwhile, since the thickness of the free end of the abutting portion 135 is smaller than the thickness of the end of the abutting portion 135 connected to the sleeve portion 131, the elasticity of the free end of the abutting portion 135 is large, which is beneficial for the free end of the abutting portion 135 to abut against the first guide portion 210 and to be elastically deformed. The abutting portion 135 presses the first guide portion 210 and is elastically deformed by the gravity of the developing cartridge 100 itself, and the chip holder 130 is rotated by the reaction force generated by the first guide portion 210. Thereby, the portion of the abutting portion 135 abutting against the first guide portion 210 gradually approaches the sleeve portion 131, and then the chip holder 130 continuously rotates, thereby moving the holding portion 133 toward the second guide portion 220 in the third direction and simultaneously moving upward in the second direction.

Finally, when the chip holder 130 is rotated to the position where the mounting portion 1334 of the holding portion 133 is aligned with the second guide portion 220, since the size of the mounting portion 1334 is equal to that of the second guide portion 220 and the chip 300 is mounted at a position where the electrical contact 310 is exactly corresponding to the probe 221, the electrical contact 310 of the chip 300 is exactly contacted with the probe 221 to achieve electrical connection while the mounting portion 1334 is exactly aligned with the second guide portion 220. Also, since the top of the second guide portion 220 has a top wall protruding in parallel with the third direction, the top of the holding portion 133 is stopped by the top wall, and the chip holder 130 stops rotating.

When the developing cartridge 100 is taken out from the developing chamber of the printer, the developing cartridge 100 can be vertically taken out, however, due to the abutment of the top wall protruding above the second guide part 220, a large external force needs to be applied, and the electrical contact 310 and the probe 221 are damaged.

The developing cartridge 100 should be biased in a direction away from the second guide portion 220 (e.g., in a third direction on the side of the second guide portion 220), and since the abutting portion 135 has elasticity, the abutting portion 135 moves in the direction away from the second guide portion 220 after being biased, and at the same time, the holding portion 133 is separated from the second guide portion 220, and the electrical contact 310 is electrically disconnected from the probe 221. The developing cartridge 100 may then be taken out in the second direction.

When the developing cartridge 100 is taken out from the developing cartridge of the printer in a proper manner, the gravity of the developing cartridge 100 does not apply a force to the first guide portion 210, so that the abutting portion 135 does not abut against the first guide portion 210, and at the same time, the abutting portion 135 loses a reaction force of the first guide portion 210, so that the chip holder 130 starts to be reversed at a certain angle. Finally, the chip holder 130 may be removed from the supporting shaft 120, thereby performing a separating operation.

Another embodiment of the present application also provides a developing cartridge 100, the developing cartridge 100 being different from the above-described developing cartridge 100 in that the extending directions of the holding portion 133 and the abutting portion 135 are different, and other features of the developing cartridge 100 are consistent with those of the above-described developing cartridge 100. Referring to fig. 6, fig. 6 is a schematic structural diagram of another chip frame 130 according to an embodiment of the present disclosure. The abutment portion 135 extends along one side of the socket portion 131, and the holding portion 133 extends along the other side of the socket portion 131 in a direction away from the abutment portion 135.

Correspondingly, the top of the second guiding portion 220 is not provided with a side wall, the bottom is provided with a side wall (i.e. a bottom wall, a blocking wall 224), and the left and right sides can also be provided with side walls to ensure that the rotation of the chip frame 130 is not affected and that the chip 300 is rotated to a proper position to stop rotating.

Next, the mounting process of the developing cartridge 100 will be described with reference to fig. 3 and 6.

When the chip holder 130 is mounted on the support shaft 120, the sleeve portion 131 is fitted on the support shaft 120 in a mounting direction in which the holding portion 133 is close to the second guide portion 220 and the abutting portion 135 is away from the second guide portion 220. Meanwhile, the straight line on which the end of the free end of the abutting portion 135 is located is kept parallel to the width direction of the first guide portion 210. Will developing cartridge 100 is followed the second direction from last down insert to during the developing chamber of printer developing cartridge 100 is under the effect of self gravity, butt portion 135 extrudes first guide portion 210 just takes place elastic deformation, chip frame 130 receives the reaction force that first guide portion 210 produced and rotates. Thereby, the portion of the abutting portion 135 abutting against the first guide portion 210 gradually approaches the sleeve portion 131, and then the chip holder 130 continuously rotates, thereby moving the holding portion 133 toward the second guide portion 220 in the third direction and, at the same time, moving downward in the second direction.

Finally, when the chip holder 130 is rotated to the position where the mounting portion 1334 of the holding portion 133 is aligned with the second guide portion 220, since the size of the mounting portion 1334 is equal to that of the second guide portion 220 and the chip 300 is mounted at a position where the electrical contact 310 is exactly corresponding to the probe 221, the electrical contact 310 of the chip 300 is exactly contacted with the probe 221 to achieve electrical connection while the mounting portion 1334 is exactly aligned with the second guide portion 220.

It is to be noted that, in the above embodiment, the chip 300 including the electric contacts 310 is fixed in the mounting groove 1336 of the holding portion 133. However, only the electrical contacts 310 capable of contacting the probes 221 may be exposed in the mounting grooves 1336 of the holding part 133, with the portions of the chip 300 other than the electrical contacts 310 being located at other portions of the developing cartridge 100 or hidden in the holding part 133. Further, the first direction and the second direction may not be perpendicular to each other. Further, the second direction and the third direction may not be perpendicular to each other. Further, the first direction and the third direction may not be perpendicular to each other. The specific shape of cassette 110 may be different from that shown in the various figures of the present application.

The embodiment of the present application further provides a printing apparatus, which includes a printer and the above-mentioned developing cartridge 100, the developing cartridge 100 is detachably mounted to the printer, the abutting portion 135 contacts with the first guiding portion 210 when the developing cartridge 100 is mounted to the printer, and moves the holding portion 133 toward the probe 221 under the interaction with the first guiding portion 210, so that the electrical contact 310 of the chip 300 on the holding portion 133 contacts with the probe 221.

In summary, the embodiments of the present application provide a developing cartridge. The printer includes first guide portion and is provided with the second guide portion of metal probe.
