Description

Processing box and processing box assembly Technical Field

[0001] This invention relates to the field of electronic imaging equipment, and more particularly to a processing cartridge that is detachably mounted in an electronic imaging equipment and a processing cartridge assembly having the processing cartridge. Background Technology

[0002] The processing cartridge is detachably installed in the imaging device. Generally, the processing cartridge is driven by the device-side drive component in the imaging device to perform imaging work. There is a device-side drive component whose main drive gear can extend and retract axially (in the direction of the rotation axis of the rotating component in the processing cartridge). The main drive gear includes a coaxial first main-side gear and a second main-side gear, which respectively contact the cartridge-side drive component in the processing cartridge. The cartridge-side transmission gear in the cartridge-side drive component receives the device driving force to make the gear assembly rotate, thereby causing the rotating components such as the photosensitive drum, developing roller, and stirring component in the processing cartridge to rotate, and forming an image on the imaging medium through the principle of electrostatic imaging.

[0003] During imaging in the processing box, in order to prevent the main drive gear from retracting and causing an interruption in the transmission of driving force, a limiting device that restricts the retraction of the drive gear needs to be installed in the processing box. Summary of the Invention

[0004] This invention provides a processing box to solve the above-mentioned technical problems. The specific solution is as follows:

[0005] A processing box is detachably mounted to an imaging device equipped with a device-side drive member. The device-side drive member has a rotation axis parallel to the longitudinal direction and is movable relative to the imaging device along the longitudinal direction. The device-side drive member is provided with at least a coaxial first main body side gear and a second main body side gear. The processing box includes: a rotating member extending along the longitudinal direction and having a rotation axis parallel to the longitudinal direction; a processing box housing for rotatably supporting the rotating member; and a box-side drive member disposed at the longitudinal end of the processing box for interaction with the device-side drive member. The device-side drive member serves to receive the driving force provided by the imaging device and drive the rotating component to rotate, wherein the rotation axis of the device-side drive member coincides with the rotation axis of at least one of the rotating components; a limiting member is disposed at the longitudinal end of the processing box for interacting with the device-side drive member to receive a braking force opposite to the direction of the driving force, and the limiting member does not drive the rotating component to rotate; along the longitudinal direction, the side of the processing box where the device-side drive member is disposed is the driving side, and the side opposite the driving side is the non-driving side, and at least a portion of the limiting member is further away from the non-driving side than the device-side drive member. By providing a limiting member on the driving side of the processing box, the device-side drive member can be prevented from disengaging from the device-side drive member.

[0006] In some embodiments, the rotating component includes at least a developing roller carrying toner and a photosensitive drum that receives toner supply from the developing roller to form an electrostatic latent image, the developing roller and the photosensitive drum being disposed opposite to each other; the cartridge-side drive component is a cartridge-side transmission gear disposed at the longitudinal end of the photosensitive drum, the rotation axis of the cartridge-side drive gear being coaxial with the rotation axis of the photosensitive drum; the cartridge-side transmission gear is configured to mesh with the first body-side gear and / or the second body-side gear to receive driving force.

[0007] In some embodiments, the limiting element is a vacant gear disposed at the longitudinal end of the photosensitive drum. The vacant gear is used to directly or indirectly mesh with the device-side drive component. The rotation axis of the vacant gear does not coincide with the rotation axis of the cartridge-side drive gear, which helps to reduce the load on the cartridge-side drive gear and improve the service life of the processing cartridge.

[0008] In some embodiments, the limiting element is a protrusion extending from the processing box housing, the protrusion including a first limiting portion that engages or abuts with the device-side drive element. By providing multiple limiting element embodiments, the compatibility and usability of the processing box can be improved to accommodate a wider variety of device environments.

[0009] In some embodiments, when the box-side drive gear meshes with the first body-side gear and / or the second body-side gear, the meshing backlash J between the box-side drive gear and the first body-side gear and / or the second body-side gear is in the range of 0 < J ≤ 0.5 mm. By reducing the movement space of the teeth, the meshing between the box-side drive gear and the first body-side gear and / or the second body-side gear is made tighter, thereby preventing them from disengaging.

[0010] In some embodiments, the limiting member is configured as an elastic layer attached to the outer peripheral surface of the box-side drive gear; when the box-side drive gear meshes with the first main body side gear and / or the second main body side gear, the box-side drive gear and the first main body side gear and / or the second main body side gear are configured for an interference fit. During meshing, the elastic member undergoes elastic deformation due to the meshing of the first main body side gear and / or the compression of the second main body side gear, thereby making the meshing of the two more tight.

[0011] In some embodiments, the processing box housing includes a first end cap disposed at a longitudinal end, wherein the restraint is exposed to the outside through an exposure port provided on the first end cap. Various combinations of restraints are provided.

[0012] In some embodiments, the limiting element includes a contact portion for restricting longitudinal movement of the device-side drive component, the contact portion being movable between a shielded state and an exposed state; in the shielded state, at least the contact portion is shielded by the first end cap in the longitudinal direction, and in the exposed state, at least the contact portion is not shielded by the first end cap in the longitudinal direction. When the processing cassette is not installed in place, the shielding of the contact portion by the first end cap prevents the installation of the interferometric imaging device onto the processing cassette.

[0013] In some embodiments, the limiting element further includes a trigger movable relative to the processing cartridge housing, the trigger being configured to receive an external force to directly or indirectly force the contact portion to move from the obscured state to the exposed state. During processing cartridge installation, the device environment provides an external force to force the contact portion to switch between the obscured and exposed states, making the installation process of the processing cartridge simpler and eliminating the need for manual triggering or other additional installation steps.

[0014] The present invention also provides a processing cartridge assembly detachably mounted to an imaging device having a device-side drive. The processing cartridge assembly includes: a processing cartridge, which may include a processing cartridge housing and a rotating member rotatably disposed within the processing cartridge housing, the rotating member having a rotation axis parallel to the longitudinal direction; and an accessory, configured as a component independent of the processing cartridge, the accessory for abutting against the device-side drive to restrict movement of the device-side drive in the longitudinal direction. This provides another embodiment for mounting on an imaging device to prevent the device-side drive from moving longitudinally and disengaging from the cartridge-side drive, increasing the compatibility of the restrictor.

[0015] A processing box and processing box assembly having at least one of the above embodiments, by setting a limiting member at a position further away from the non-driving side than the box-side drive member in the processing box, allows the limiting member to act first on the device-side drive member, thereby limiting the device-side drive member from retracting to the left in the longitudinal direction, thus effectively preventing the device-side drive member from disengaging from the box-side transmission member and ensuring the stability of the drive force transmission; in addition, the various embodiments of the limiting member in this invention are conducive to the processing box being compatible with more diverse device environments, thereby improving the compatibility and practicality of the processing box.

[0056] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0057] Figures 1A and 1B are schematic diagrams of the processing box and device-side drive components involved in the present invention.

[0058] The processing box C can be detachably installed into an imaging device equipped with a device-side drive unit T. For the sake of accuracy and ease of understanding, the processing box C is defined as having a left and a right side as shown in Figures 1A-1B, where the left and right directions are the length direction, longitudinal direction, or axial direction of the processing box C, and the processing box C extends along the longitudinal direction.

[0059] Specifically, the device-side drive component T has a rotation axis LT parallel to the longitudinal direction, as shown in Figure 2A. The device-side drive component T is provided with a coaxial first main body side gear T2 and a second main body side gear T3. Before the processing box C is installed in the imaging device, the device-side drive component T extends to the right along the longitudinal direction under the action of an elastic element (not shown) provided in the imaging device. During the installation of the processing box C, when the device-side drive component T is subjected to a force to the left, it retracts to the left along the longitudinal direction.

[0060] As shown in Figures 36A and 36B, the device-side drive component T also includes a main body-side drive force receiver T4 and a main body-side rotation shaft T5. The main body-side drive force receiver T4, the main body-side rotation shaft T5, the first main body-side gear T2, and the second main body-side gear T3 are coaxially arranged along the longitudinal direction / rotation axis LT. The second main body-side gear T3 is located between the main body-side drive force receiver T4 and the first main body-side gear T2. For example, the main body-side drive force receiver T4, the first main body-side gear T2, and the second main body-side gear T3 are all arranged on the main body-side rotation shaft T5, or the main body-side rotation shaft T5 connects the second main body-side gear T3 and the main body-side drive force receiver T4. Further, the main body-side rotation shaft T5 is also provided with a recessed portion T7 and a stepped surface T6. Along the longitudinal direction, the stepped surface T6 and the second main body-side gear T3 are located on both sides of the recessed portion T7, respectively.

[0061] As shown in Figures 1A-1B, the processing cartridge C includes a rotating component and a processing cartridge housing that rotatably supports the rotating component. The rotating component can be any one of the following: developing roller 11, powder feeding component, stirring component, photosensitive drum 21, charging roller 23 (as shown in Figure 30). The rotating component is configured to extend in the longitudinal direction. The processing cartridge housing includes the following supporting components: developing housing 10, photosensitive housing 20, cover (side cover 22, first end cover 12, and second end cover 13), as well as other supporting components other than the rotating component, such as a bracket detachably connected to the processing cartridge C. In a specific embodiment, the processing cartridge C includes a developing unit 1 and a photosensitive unit 2 movably connected to each other. The developing unit 1 includes a developing housing 10 containing toner and a developing roller 11, a powder feeding component, and a stirring component rotatably disposed on the developing housing 10. The photosensitive unit 2 includes a photosensitive housing 20 and a photosensitive drum 21 and a charging roller 23 rotatably disposed on the photosensitive housing 20. The charging roller 23 is used to charge the surface of the photosensitive drum 21, so that the surface of the charged photosensitive drum can form an electrostatic latent image after being irradiated by a laser beam carrying imaging information. Specifically, the developing roller 11 can rotate about a developing roller rotation axis L11 parallel to the longitudinal direction, and the photosensitive drum 21 can rotate about a photosensitive drum rotation axis L21 parallel to the longitudinal direction. Along the radial direction of the developing roller 11 or the photosensitive drum 21, the developing roller 11 and the photosensitive drum 21 are arranged opposite to each other. The radial direction is set to intersect the longitudinal direction, preferably the radial direction is perpendicular to the longitudinal direction. The developing roller 11 serves as a toner carrier. The charged toner attached to its surface is adsorbed by the photosensitive drum 21, so that the electrostatic latent image on the surface of the photosensitive drum 21 is developed to form a visible toner image. In other words, the developing roller 11 is used to supply the toner carried on its surface to the photosensitive drum 21.

[0062] The processing box C also includes a cover at the longitudinal end. The cover includes at least one end cover at the longitudinal end of the developing housing 10 and at least one side cover at the longitudinal end of the photosensitive housing 20. Specifically, the cover is a first end cover 12 and a second end cover 13 at the longitudinal end of the developing unit 1 / developing housing 10 and connected to the developing housing 10, and a side cover 22 at the longitudinal end of the photosensitive unit 2 / photosensitive housing 20 and connected to the photosensitive housing 20. In the longitudinal direction, the first end cover 12 and the second end cover 13 are arranged opposite to each other. The first end cover 12 and the second end cover 13 can be used to support the developing roller 11, and the side cover 22 can be used to support the photosensitive drum 21. Furthermore, the side cover 22 and the photosensitive housing 20 can be integrally formed or separately formed.

[0063] The processing box C also includes a box-side drive 3 (as shown in Figure 2A) disposed at its longitudinal end. The box-side drive 3 interacts with the device-side drive T to receive the driving force provided by the imaging device, thereby driving the rotating component to rotate. Along the longitudinal direction, the side where the box-side drive 3 is disposed is the driving side, and the other side is the non-driving side.

[0064] Example 1

[0065] Figures 2A and 2B are schematic diagrams of the engagement of the box-side drive member and the device-side drive member according to Embodiment 1 of the present invention; Figures 3A and 3B are schematic diagrams of the box-side drive member after the processing box has hidden parts according to Embodiment 1 of the present invention; Figure 4 is a schematic diagram of the processing box according to Embodiment 1 of the present invention after being cut along a direction perpendicular to the longitudinal direction; Figure 5A is a schematic diagram of the processing box according to Embodiment 1 of the present invention when it is installed on the imaging device and cut along the cutting line AA in Figure 2B; Figure 5B is a schematic diagram of the processing box according to Embodiment 1 of the present invention when it is installed on the imaging device and cut along the cutting line BB in Figure 2B.

[0066] As shown in Figures 2A-2B and 3A-3B, the cartridge-side drive component 3 includes at least a cartridge-side transmission gear 31. The cartridge-side transmission gear 31 is disposed at one longitudinal end of the photosensitive drum 21 and is coaxial with the photosensitive drum 21. That is, the rotation axis L31 of the cartridge-side transmission gear 31 coincides with the rotation axis L21 of the photosensitive drum 21. The cartridge-side transmission gear 31 meshes with the device-side drive component T to receive the driving force provided by the device-side drive component T, causing the photosensitive drum 21 to rotate around the photosensitive drum rotation axis L21. The processing cartridge C also includes a limiting component 4, which is not coaxial with the cartridge-side drive component 3. Specifically, the limiting component 4 includes at least one braking gear 40, which is coaxial with the cartridge-side transmission gear 31. That is, the rotation axis L40 of the braking gear 40 coincides with the rotation axis L31 of the cartridge-side transmission gear 31. 1. Non-overlapping, which helps to reduce the load on the cartridge-side drive gear 31 and improve the service life of the processing cartridge C; In this embodiment, in the longitudinal direction, the brake gear 40 is located to the left of the cartridge-side drive gear 31, that is, in the longitudinal direction, the brake gear 40 is farther away from the non-drive side than the cartridge-side drive gear 31, so that the brake gear 40 / limiting member 4 first acts with the device-side drive member T to limit the device-side drive member T from disengaging in the longitudinal direction. Alternatively, the brake gear 40 is located to the right of the cartridge-side drive gear 31, and in the longitudinal direction, the brake gear 40 is closer to the non-drive side than the cartridge-side drive gear 31. More specifically, the brake gear 40 is located on the developing unit 1 / photosensitive unit 2. The brake gear 40 is used to mesh with the device-side drive member T to receive a braking force opposite to the direction of the driving force, thereby preventing the device-side drive member T from retracting to the left in the longitudinal direction.

[0067] When the processing cartridge C is installed into the imaging device, the cartridge-side drive gear 31 receives the driving force provided by the first main body side gear T2, and the brake gear 40 receives the braking force provided by the second main body side gear T3. The brake gear 40 meshes / engages with the second main body side gear T3 to prevent the device-side drive component T from disengaging from the cartridge-side drive gear 31. Since the driving force is greater than the braking force, the cartridge-side drive gear 31 is driven by the first main body side gear T2, causing the photosensitive drum 21 to rotate in the direction indicated by arrow R2. Alternatively, the cartridge-side drive gear 31 receives the driving force provided by the second main body side gear T3, and the brake gear 40 receives the braking force provided by the first main body side gear T2. The brake gear 40 meshes / engages with the first main body side gear T2 to prevent the device-side drive component T from disengaging from the cartridge-side drive gear 31. Similarly, since the driving force is greater than the braking force, the cartridge-side drive gear 31 is driven by the second main body side gear T3, causing the photosensitive drum 21 to rotate in the direction indicated by arrow R2. In addition, the cartridge-side drive gear 31 meshes with the developing roller gear 32 located at the end of the developing roller 11, so the developing roller 11 is driven to rotate around the developing roller axis L11 in the direction shown by arrow R1.

[0068] In one embodiment, the brake gear 40 is at least one idler gear disposed at the axial end of the photosensitive drum 21. Idle means that the gear does not drive the photosensitive drum 21 to rotate, nor does it drive other rotating components to rotate. The rotation axis L40 of the idler gear 40 does not coincide with the rotation axis L21 of the photosensitive drum 21 / the rotation axis L31 of the box-side transmission gear 31 (as shown in Figure 3A). Projected from left to right along the longitudinal direction, at least a portion of the idler gear 40 is located within the projection surface S21 of the photosensitive drum 21 (as shown in Figure 4), so as to avoid the photosensitive drum 21 being subjected to unstable force due to the excessive distance between the rotation axis L40 of the idler gear 40 and the rotation axis L21 of the photosensitive drum. In addition, it is beneficial to make the structure of the processing box C more compact.

[0069] In one embodiment, the brake gear 40 is an idle gear coaxially arranged with the developing roller gear 32. The idle means that the gear does not drive the developing roller 11 to rotate, nor does it drive other rotating parts to rotate. Alternatively, the brake gear 40 is arranged in other positions that are not coaxial with the photosensitive drum 21, so as to directly or indirectly engage with the equipment-side drive member T to generate braking force, so as to prevent the equipment-side drive member T from disengaging from the cartridge-side transmission gear 31.

[0070] Furthermore, the brake gear 40 is made of materials such as rubber wheels or rubber treads to increase friction, in order to prevent the equipment-side drive component T from disengaging.

[0071] Furthermore, the box-side transmission gear 31 and the brake gear 40 are helical gears with convex teeth extending in the direction of rotation. The gears are involute gears. To achieve a better anti-disengagement effect, the box-side transmission gear 31 can also be a non-involute gear, such as a thin spur gear or a flat gear with intermittent teeth. The cross-sectional shape of the convex teeth is not limited to trapezoids, but can also be rectangular, triangular, mountain-shaped formed by curves, or chamfered, etc., as long as it can prevent the equipment-side drive component T from disengaging from the box-side drive component 3 / box-side transmission gear 31.

[0072] Compared to existing technologies, the brake gear structure in this embodiment is simplified, which is beneficial for the implementation of the solution and for mass production. In addition, the multiple implementation schemes of the brake gear help the processing box to be compatible with a wider variety of equipment environments, thereby improving the compatibility and practicality of the processing box.

Example 2

[0074] Figure 6 is an exploded view of some components of the processing box according to Embodiment 2 of the present invention; Figure 7A is a schematic diagram of the drive side of the processing box according to Embodiment 2 of the present invention; Figure 7B is a schematic diagram of the engagement of the box-side drive member and the device-side drive member according to Embodiment 2 of the present invention.

[0075] In this embodiment, the cartridge-side drive member 3 includes a cartridge-side transmission gear 31 disposed at one axial end of the photosensitive drum 21. The limiting member 4 is used to engage with the device-side drive member T to limit its movement in the longitudinal / axial direction, thereby preventing the device-side drive member T from disengaging from the cartridge-side transmission gear 31. The structure of the limiting member 4 is different from that in Embodiment 1, as follows.

[0076] As shown in Figures 7A-7B, the limiting member 4 is configured as a protrusion extending from the processing box housing, and at least a portion of the limiting member 4 is further away from the non-driving side than the box-side drive member 3. Specifically, in this embodiment, the limiting member 4 includes at least a first limiting part 411. In this embodiment, the limiting member 4 also includes a second limiting part 412 and a third limiting part 413. As one embodiment, the first limiting part 411 and the second limiting part 412 are protrusions extending from the side cover 22, and the third limiting part 413 is a protrusion extending from the first end cover 12. In the longitudinal direction, the first limiting part 411 is further away from the non-driving side than the second limiting part 412 and the third limiting part 413, and is used to limit the displacement of the device-side drive member T to the left. The first limiting part 411 is further away from the non-driving side than the box-side drive member 3. In the longitudinal direction, the second limiting part 412 and the third limiting part 413 are closer to the non-driving side than the first main body side gear T2, and are used to limit the rightward movement of the device-side drive member T. The displacement is along the radial direction of the device-side drive member T. The second limiting part 412 and the third limiting part 413 are located on both sides of the rotation axis LT of the device-side drive member, respectively. When the first limiting part 411 cooperates with the device-side drive member T, the displacement of the device-side drive member T in the longitudinal direction can be limited. When the first limiting part 411, the second limiting part 412 and the third limiting part 413 cooperate with the device-side drive member T at the same time, the force on the device-side drive member T is more balanced, and the displacement in the longitudinal direction and the displacement in the radial direction of the device-side drive member T can be limited at the same time. In this embodiment, the first limiting part 411 can be used in conjunction with at least one of the second limiting part 412, the third limiting part 413 or other limiting parts provided in the processing box C. The combination of the limiting parts is not limited here.

[0077] Specifically, the first limiting part 411, the second limiting part 412 and the third limiting part 413 are used to engage or abut with the equipment-side drive member T to prevent the equipment-side drive member T from disengaging from the box-side transmission gear 31. This embodiment can eliminate the brake gear of the first embodiment, simplify the solution to prevent the equipment-side drive member T from disengaging, make it easier to implement, and also make the structure of the processing box C simpler.

[0078] In one embodiment, the limiting member 4 may also be provided on components of the processing box housing other than the side cover 22 and / or the first end cover 12.

[0079] Furthermore, the limiting member 4 can also be configured as a detachable component, attached to the processing cartridge C before installation, so as to prevent detachment during the developing process; or the limiting member 4 can be configured as a movable component connected to the processing cartridge housing other than the side cover 22 and / or the first end cover 12, and the movement is not limited to rotation, translation or eccentric movement, etc.

[0080] Furthermore, the limiting member 4 can also be an elastic member attached to a component of the processing box housing other than the side cover 22 and / or the first end cover 12, such as an elastic cantilever, elastic rope, rubber block, etc. The elastic member is not easily worn and can improve the service life of the component; or, when the device side drive member T is set to be a component that has magnetism or is capable of generating magnetism in at least part, the limiting member 4 can also be a component with magnetism opposite to that of the device side drive member T.

[0081] Furthermore, the position where the limiting member 4 engages with the device-side drive member T is either the gearless smooth part of the device-side drive member T or the gear part of the device-side drive member T. The contact surface between the limiting member 4 and the device-side drive member T is preferably a raised surface or a grooved surface, used to embed into the gear gap of the first main body side gear T2 and / or the second main body side gear T3, so as to achieve a better anti-disengagement effect.

[0082] The above-mentioned anti-detachment solutions can be used in combination to be compatible with a wider variety of equipment environments, thereby improving the compatibility and practicality of the processing box C.

[0083]

Example 3

[0084] Figure 8 is a schematic diagram of the drive side of the processing box according to Embodiment 3 of the present invention; Figure 9 is a schematic diagram of the box-side drive member and the device-side drive member engaging according to Embodiment 3 of the present invention; Figure 10 is a schematic diagram of the box-side drive member and the device-side drive member engaging according to Embodiment 3 of the present invention, when cut along the cutting line BB in Figure 2B.

[0085] As shown in Figures 8 to 10, in this embodiment, the cartridge-side drive component 3 only includes a cartridge-side transmission gear 31 disposed at one axial end of the photosensitive drum 21.

[0086] Specifically, as shown in Figure 9, the box-side transmission gear 31 is used to mesh with one of the first main body side gear T2 and the second main body side gear T3 of the equipment-side drive member T to receive driving force, or the box-side transmission gear 31 is configured to mesh with both the first main body side gear T2 and the second main body side gear T3 to receive driving force.

[0087] Next, taking the state when the box-side transmission gear 31 meshes with the first main body side gear T2 as an example, the following definitions are made: As shown in Figure 10, along the rotation direction R2 of the box-side transmission gear 31, the box-side transmission gear 31 has adjacent first driven teeth 3111 and second driven teeth 3112. Along the rotation direction R1 of the first main body side gear T2, the first main body side gear T2 has adjacent first driving teeth T211 and second driving teeth T212. When the box-side transmission gear 31 meshes with the first main body side gear T2, the first driving tooth T211 enters the space formed by the two adjacent driven teeth before the second driving tooth T212. In the direction indicated by arrow R1, the first side T2111 of the first driving tooth T211 and the first driven tooth T212... The moving tooth 3111 abuts against the drive gear 31 on the drive box side to rotate. A tooth gap J is formed between the second side T2112 of the first drive tooth T211 and the second driven tooth 3112. In the direction shown by arrow R1, the first side T2111 is located downstream of the second side T2112. An active space S for the second driven tooth 3112 is formed between the first drive tooth T211 and the second drive tooth T212. As the first main body side gear T2 continues to rotate, the second driven tooth 3112 enters between the first drive tooth T211 and the second drive tooth T212. That is, the second driven tooth 3112 enters the active space S. Immediately afterwards, the second drive tooth T212 abuts against the second driven tooth 3112 to transmit driving force.

[0088] As shown in Figure 10, when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3, the meshing clearance J between the box-side transmission gear 31 and the first main body side gear T2 and / or the second main body side gear T3 is in the range of 0 < J ≤ 0.5 mm, preferably 0.2 mm. This reduces the movement space of the teeth when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3, thereby making the meshing of the box-side transmission gear 31 with the first main body side gear T2 and / or the second main body side gear T3 tighter. This prevents the first main body side gear T2 and / or the second main body side gear T3 from disengaging under reaction force, thus preventing the equipment-side drive component T from disengaging from the box-side transmission component 3 / The box-side transmission gear 31 disengages; conversely, if the meshing backlash J when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3 is too large (J>0.5mm), it will result in excessive play space for the teeth of the box-side transmission gear 31. This will cause the box-side transmission gear 31 to vibrate due to unbalanced force when it simultaneously receives driving and braking forces. Furthermore, it will cause the first main body side gear T2 and / or the second main body side gear T3 to not mesh tightly with the box-side transmission gear 31. Consequently, the first main body side gear T2 and / or the second main body side gear T3 will be subjected to reaction force and move to the left, eventually disengaging from the box-side transmission gear 31. This will result in reduced or interrupted driving force transmission accuracy.

[0089] Furthermore, the box-side transmission gear 31 is a helical gear with convex teeth extending in the direction of rotation. The gear is an involute gear. To achieve a better anti-disengagement effect, the box-side transmission gear 31 can also be a non-involute gear, such as a thin spur gear or a flat gear with intermittent teeth. The cross-sectional shape of the convex teeth is not limited to trapezoids, but can also be rectangular, triangular, mountain-shaped formed by curves, or chamfered, etc., as long as it can prevent the equipment-side drive component T from disengaging from the box-side drive component 3 / box-side transmission gear 31.

[0090]

Example 4

[0091] Figure 11 is a schematic diagram of the drive side of the processing box according to Embodiment 4 of the present invention; Figure 12 is a schematic diagram of the engagement of the box-side drive member and the device-side drive member according to Embodiment 4 of the present invention; Figures 13A and 13B are schematic diagrams of the box-side drive member according to Embodiment 4 of the present invention.

[0092] In this embodiment, the cartridge-side drive member 3 only includes a cartridge-side transmission gear 31 disposed at one axial end of the photosensitive drum 21, and the processing cartridge C also includes a limiting member 4 disposed at its longitudinal end. The limiting member 4 is used to prevent the device-side drive member T from disengaging from the cartridge-side drive member 3 / cartridge-side transmission gear 31.

[0093] Specifically, as shown in Figure 12, the box-side transmission gear 31 is used to mesh with one of the first main body side gear T2 and the second main body side gear T3 of the equipment-side drive member T to receive driving force, or the box-side transmission gear 31 is configured to mesh with both the first main body side gear T2 and the second main body side gear T3 to receive driving force.

[0094] As shown in Figures 13A and 13B, in this embodiment, the limiting member 4 is coaxially arranged with the box-side transmission gear 31. Specifically, the limiting member 4 is an elastic member 42, which is an elastic layer attached to the outer peripheral surface of the box-side transmission gear 31. The elastic member 42 can rotate together with the box-side transmission gear 31. When the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3, the box-side transmission gear 31 and the first main body side gear T2 and / or the second main body side gear T3 are in an interference fit. Furthermore, when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3, the elastic member 42 is squeezed by the first main body side gear T2 and / or the second main body side gear T3 and undergoes elastic deformation, so that the box-side transmission gear 31 meshes more tightly with the first main body side gear T2 and / or the second main body side gear T3, thereby preventing the equipment-side drive member T from disengaging from the box-side drive member 3 / box-side drive gear 31. In this embodiment, an elastic element 42 is provided on the outer peripheral surface of the transmission gear 31 on the box side, which simplifies the solution to prevent the drive component T on the equipment side from disengaging, and makes it easier to implement.

[0095] In some embodiments, the elastic element 42 is an elastic component, such as rubber, sponge, etc.

[0096] In some embodiments, the limiting member 4 may also be a tooth provided on the box-side transmission gear 31, the tooth being elastic, and the tooth being able to elastically deform when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3.

[0097] In some embodiments, the elastic element 42 is attached to the surface of the transmission gear 31 on the side of the box by means of adhesive bonding, hot melt attachment, snap-fit, etc.

[0098] In some embodiments, this embodiment can be combined with Embodiment 3. That is, when the box-side transmission gear 31 meshes with the first main body side gear T2 and / or the second main body side gear T3, the meshing tooth clearance is 0 < J ≤ 0.5 mm, preferably 0.2 mm. At the same time, the surface of the box-side transmission gear 31 is attached with an elastic element 42, or the teeth on the box-side transmission gear 31 are elastic. This can further prevent the equipment-side drive member T from disengaging from the box-side drive member 3 / box-side transmission gear 31, and can also make the processing box compatible with more diverse equipment environments, thereby improving the compatibility and practicality of the processing box.

[0099] Example 5

[0100] Figure 14 is a schematic diagram of the drive side of the processing box according to Embodiment 5 of the present invention; Figure 15 is a schematic diagram of the engagement of the box-side drive member and the device-side drive member according to Embodiment 5 of the present invention.

[0101] Based on Embodiment 1, this embodiment optimizes the position of the limiting member 4, as detailed below.

[0102] In this embodiment, the cartridge-side drive member 3 only includes a cartridge-side transmission gear 31 disposed at one axial end of the photosensitive drum 21, and the processing cartridge C also includes a limiting member 4 disposed at its longitudinal end. The limiting member 4 is used to prevent the device-side drive member T from disengaging from the cartridge-side drive member 3 / cartridge-side transmission gear 31.

[0103] Specifically, as shown in Figure 15, the box-side transmission gear 31 is used to mesh with one of the first main body side gear T2 and the second main body side gear T3 of the equipment-side drive member T to receive driving force, or the box-side transmission gear 31 is configured to mesh with both the first main body side gear T2 and the second main body side gear T3 to receive driving force.

[0104] As shown in Figures 14 and 15, the limiting member 4 is coaxial with the box-side drive member 3. Specifically, the limiting member 4 is an idler wheel 43 coaxial with the photosensitive drum 21 / box-side transmission gear 31. When the box-side transmission gear 31 meshes with one of the first main body side gear T2 and the second main body side gear T3, the idler wheel 43 is used to contact the other of the first main body side gear T2 and the second main body side gear T3, so that friction is generated between the idler wheel 43 and the device-side drive member T. The direction of the friction is not parallel to the disengagement direction of the device-side drive member T, thereby preventing the device-side drive member T from disengaging from the box-side drive member 3 / box-side transmission gear 31. Furthermore, in the longitudinal direction, the idler wheel 43 is farther away from or closer to the non-drive side than the box-side drive gear 31. The outer peripheral surface of the idler wheel 43 does not have meshing teeth / protrusions. The idler wheel 43 is made of a material that can generate friction, such as rubber or sponge, and the surface roughness of the material that can generate friction is high.

[0105] Example 6

[0106] Figure 16 is an exploded view of the limiting member and the processing box housing according to Embodiment 6 of the present invention after separation; Figure 17 is a state diagram of the trigger member and the contact member according to Embodiment 6 of the present invention when they are in contact with each other; Figures 18A and 18B are cross-sectional views of the device-side drive member after cutting along a plane perpendicular to the longitudinal direction and passing through the recess when the contact member according to Embodiment 6 of the present invention is in the shielded state and the exposed state, respectively.

[0107] In this embodiment and the following embodiments, components identical to those in the above embodiments will be numbered the same, and structures identical to those in the above embodiments will not be described again here. As shown in FIG16, the first end cover 12 includes an end cover body 121 and an exposure opening 123 disposed on the end cover body 121. The photosensitive drum 21 is rotatably supported by a side cover 22. The side cover 22 is connected to the end cover body 121. Preferably, the side cover 22 and the end cover body 121 are integrally formed. In this case, the side cover 22 can be regarded as part of the first end cover 12, and the exposure opening 123 can also be regarded as disposed on the side cover. On 22, through the exposure port 123, the limiting member 4 can contact the device-side drive member T to restrict the device-side drive member T from retracting. For example, in the direction intersecting the longitudinal direction, the limiting member 4 extends to the outside of the exposure port 123, that is, the limiting member 4 is exposed to the outside through the exposure port 123, so that the limiting member 4 contacts the device-side drive member T. Alternatively, the device-side drive member T enters the space inside the first end cover 12 for accommodating the limiting member 4 through the exposure port 123, that is, the limiting member 4 is exposed to the outside through the exposure port 123, so that the limiting member 4 contacts the device-side drive member T.

[0108] As shown in Figure 16, the limiting member 4 includes a contact member 44, a reset member 45, and a trigger member 46. In one embodiment, the contact member 44 is capable of switching between a covered state and an exposed state. In the covered state, when viewed longitudinally, the contact member 44 / contact portion 443 is not exposed outwards. In the exposed state, when viewed longitudinally, at least a portion of the contact member 44 / contact portion 443 is exposed outwards. The reset member 45 is used to hold the contact member 44 in the covered state, and the trigger member 46 is used to directly or indirectly force the contact member 44 to switch / move from the covered state to the exposed state upon receiving an external force. When the processing box C is not installed in place, the contact portion of the contact member 44 / contact portion 443 is at least covered by the first end cover 12, which can prevent the installation of the interferometric imaging device on the processing box C.

[0109] Specifically, the reset member 45 is an elastic element such as a tension spring, compression spring, disc spring, rubber, or sponge, or a magnetic element that generates magnetic force. The following description uses the reset member 45 as an example of an elastic element. The processing box C also includes a trigger member 46 that is movable relative to the processing box housing. For example, the trigger member 46 is a rod that can move relative to the processing box housing / developing housing 10 / photosensitive housing 20 / first end cap 12 / rotating member, and has a force receiving part 46a for receiving external force and a trigger part 46b for directly or indirectly forcing the contact member 44 to switch / move from the blocked state to the exposed state. Preferably, along the movement direction of the trigger member 46, the force receiving part 46a and the trigger part 46b are located at the two ends of the trigger member 46, respectively. As shown in FIG17, the contact member 44 in this embodiment can be directly triggered by the trigger member 46 to switch / move from the blocked state to the exposed state.

[0110] The contact 44 includes a contact body 441, a triggered part 442, and a contact part 443. The triggered part 442 and the contact part 443 are both disposed on the contact body 441. Their positions are not limited, as long as they can achieve their respective functions. The triggered part 442 is used to receive the external force transmitted from the trigger part 46b, thereby causing the contact 46 to overcome the reset force (elastic force) of the reset part 45 and switch / move from the blocked state to the exposed state. The contact part 443 is used to contact the device-side drive T to limit the device-side drive T from retracting to the left.

[0111] As shown in Figure 18A, when the processing box has not yet been installed into the imaging device, or when the processing box has been installed into the imaging device but the door cover 97 of the imaging device has not yet been closed, the force receiving part 46a has not yet received an external force. The triggering part 46b and the triggered part 442 can be in contact with each other or not in contact with each other, and the contact member 44 is in a blocked state. As the door cover 97 gradually closes, as shown in Figure 18B, the door cover 97 gradually applies a force (a type of external force) to the force receiving part 46a, causing the trigger member 46 to move relative to the processing box housing. As the developing housing 10, photosensitive housing 20, first end cap 12, and rotating member move, the triggering part 46b transmits the force to the triggered part 442. The contact member 44 moves toward the exposed state relative to the processing cartridge housing, developing housing 10, photosensitive housing 20, first end cap 12, and rotating member. The resetting member 45 accumulates resetting force. Under the continuous force applied by the door cover 97 toward the triggering member 46, the contact member 44 remains in the exposed state. The contact part 443 contacts the device-side drive member T, and the tendency of the device-side drive member T to retract to the left can be suppressed.

[0112] The contact portion 443 and the device-side drive member T can form at least one of surface contact, line contact, and point contact. The shape of the contact portion 443 should not be limited. When the contact portion 443 and the device-side drive member T form surface contact, the contact portion 443 will have an anti-detachment surface. This anti-detachment surface can be formed as a straight surface perpendicular to the moving direction of the contact member, or as an arc surface that extends at least partly around the main body-side drive member T. When the contact portion 443 and the device-side drive member T form line contact, the contact portion 443 can be formed as a rib protruding from the contact body 441, and the top end of the rib contacts the device-side drive member T. When the two form point contact, the number of contact points is preferably not less than two.

[0113] When the door cover 97 is opened, the force gradually decreases until it disappears. Under the reset force of the reset member 45, the contact member 44 changes from the exposed state to the blocked state. At the same time, the trigger member 46 also gradually resets. The force required for the trigger member 46 to reset can come from the reaction force applied by the contact member 44 to the trigger part 46b through the triggered part 442, or a first reset device (not shown) can be provided to contact the trigger member 46, and the trigger member 46 can be reset by using the first reset device.

[0114] As described above, the external force received by the trigger 46 in this embodiment is the force from the door cover 97. Therefore, the direction of movement of the trigger 46 can be any direction intersecting the longitudinal direction, or in other words, the direction of movement of the trigger 46 is not parallel to the longitudinal direction. Preferably, the trigger 46 moves in a direction perpendicular to the longitudinal direction.

[0115] In some embodiments, the trigger 46 is movable relative to the processing housing and is used to receive external force to directly or indirectly force the contact portion 443 to move from a blocked state to an exposed state.

[0116] In some embodiments, the trigger 46 translates along a direction perpendicular to the longitudinal direction.

[0117] In some embodiments, the trigger 46 is active by rotation. For example, when the trigger 46 receives a force from the door cover 97, it can also transmit the force to the contact 44 by rotation.

[0118] In some embodiments, the first end cap 12 further includes a first guide portion 122 disposed on the end cap body 121. The first guide portion 122 is used to guide the trigger member 46 so that the trigger member 46 can move in a predetermined direction when subjected to an external force.

[0119] In some embodiments, the reset member 45 is configured as a tension spring, with one end connected to the processing cartridge housing / developer housing 10 / photosensitive housing 20 / first end cap 12 / rotator, and the other end connected to the contact member 44.

[0120] In some embodiments, as shown in FIG18A, when the contact 44 is in a blocked state, when viewed in the longitudinal direction, at least a portion of the contact 44 overlaps with the photosensitive drum 21. This design is beneficial to reducing the size of the processing box in the direction intersecting the longitudinal direction.

[0121] In some embodiments, all the limiting members 4 are located on the driving side to simplify the structure of the processing box. In other embodiments, the limiting members 4 can also be located in other positions of the processing box according to design requirements. For example, in the longitudinal direction, only the contact member 44 is located on the driving side, that is, the contact member 44 is located on the same side as the box-side driving member 31. At least one of the reset member 45 and the trigger member 46 is located on the non-driving side, or at least one of them is located between the driving side and the non-driving side. Alternatively, the contact member 44 may not be located on the driving side. When the contact member 44 is triggered by the trigger member 46, the contact member 44 moves to the driving side.

[0122] In some embodiments, the first end cap 12 is further provided with a second guide portion 124 (as shown in FIG19). The second guide portion 124 is used to guide the movement of the contact member 44, which not only enables the contact member 44 to contact the predetermined contact position of the device-side drive member T, but also restricts the contact member 44 in the longitudinal direction, thereby restricting the movement of the device-side drive member T in the longitudinal direction by the contact member 44.

[0123] Example 7

[0124] Figure 19 is an exploded view of the limiting member and the processing box housing according to Embodiment 7 of the present invention after separation; Figure 20 is a perspective view of the guide rail in the imaging device to which the processing box according to Embodiment 7 of the present invention is applicable; Figures 21A and 21B are state diagrams of the processing box in the imaging device when the contact member according to Embodiment 7 of the present invention is in the blocked state and the exposed state, respectively.

[0125] Generally, the processing box C also includes a guide protrusion 14 disposed on the processing box housing. When the processing box C is installed and removed in the imaging device, the guide protrusion 14 cooperates with the guide rail 99 disposed in the imaging device, so that the processing box C can be guided along a predetermined path. In this embodiment, an extending and through guide hole is formed in the guide protrusion 14 in the longitudinal direction, and the guide hole serves as the first guide part 122.

[0126] Unlike Embodiment Six, in this embodiment, the trigger 46 is configured to receive external force by abutting against the inner wall 990 (hereinafter referred to as "the inner wall of the track") of the guide rail 99. Therefore, the direction of movement of the trigger 46 in this embodiment should be described as not perpendicular to the longitudinal direction. Preferably, the trigger 46 moves in a direction parallel to the longitudinal direction.

[0127] As shown in Figure 19, in this embodiment, the first guide portion 122 is a guide hole that extends and penetrates in the longitudinal direction on the end cap body 121. In the trigger member 46, at least the force receiving portion 46a is exposed through the first guide portion 122.

[0128] As shown in Figure 20, the inner wall 990 of the track forms a guide groove for guiding the installation and removal of the processing box C. The guide groove includes a front guide groove 991, a middle guide groove 995, and a rear guide groove 992. Along the installation direction A of the processing box C, the guide track 99 is provided with a front guide part 99a, a middle guide part 99c, and a rear guide part 99b in sequence. The middle guide part 99c connects the front guide part 99a and the rear guide part 99b. The front guide part 99a is provided with a front guide groove 991, the rear guide part 99b is provided with a rear guide groove 992, the middle guide part 99c is provided with a middle guide groove 995, and an inclined surface 993 that is inclined relative to the installation direction A. The inclined surface 993 is formed as part of the inner wall 990 of the track. The front guide groove 991, the middle guide groove 995, and the rear guide groove 992 are connected.

[0129] In this embodiment, the external force is the force applied by the imaging device to the trigger or the squeezing force between the trigger and the inner wall of the imaging device. The trigger directly forces the contact to move from the blocked state to the exposed state.

[0130] As shown in Figures 21A and 21B, as the processing box C is installed along the installation direction A, the force receiving part 46a moves from the front guide groove 991 through the inclined surface 993 towards the rear guide groove 992. During this process, the force receiving part 46a and the inclined surface 993 press against each other and receive a compressive force (a type of external force). At the same time, the trigger member 46 moves to the right, and the trigger part 46b triggers the contact member 44 by abutting against the triggered part 442. The contact member 44 changes / moves from a blocked state (as shown in Figure 21A) to an exposed state (as shown in Figure 21B). The reset member 45 generates a reset force, and the force receiving part 46a abuts against the inner wall 990 of the guide rail located in the rear guide groove 992. The trigger member 46 can keep the contact member 44 in the exposed state.

[0131] As the processing box C is removed from the imaging device in the opposite direction to the installation direction A, the force receiving part 46a gradually stops abutting against the inner wall 990 of the track. Under the action of the reset force of the reset member 45, the contact member 44 gradually changes from the exposed state to the blocked state. As in Embodiment Six, the trigger member 46 can be reset by the reaction force applied by the contact member 44, or it can be reset by a separately provided first reset device.

[0132] Example 8

[0133] Figures 22A and 22B are state diagrams of the processing box in the imaging device when the contact member is in an obscured state and an exposed state, respectively, according to Embodiment 8 of the present invention.

[0134] The imaging device generally includes a main component and a cover 97 that are interconnected. The main component has a left side wall, a right side wall, an upper side wall, a lower side wall, and a front side wall. The left side wall and the right side wall are spaced apart from each other in the left-right direction, and the upper side wall and the lower side wall are spaced apart from each other in the up-down direction. The front side wall connects the upper side wall, the lower side wall, the left side wall, and the right side wall. The left side wall, the right side wall, the upper side wall, the lower side wall, and the front side wall enclose a processing box receiving space. This processing box receiving space has a processing box mounting port that faces the cover. The front side wall and the processing box mounting port are spaced apart from each other. The processing box C can be installed and removed through the processing box mounting port. When the cover 97 is open, the processing box mounting port is exposed, and the processing box C can be installed or removed. When the cover 97 is closed, the processing box mounting port is closed. For ease of description, the left side wall, the right side wall, the upper side wall, the lower side wall, and the front side wall can be collectively referred to as the inner wall of the main component. The inner wall of the main component and the inner wall of the track together constitute the inner wall of the imaging device.

[0135] Unlike Embodiment 7, the external force received by the trigger 46 in this embodiment also comes from the imaging device, but the external force is received by the trigger 46 in contact with other parts of the imaging device other than the door cover 97 and the inner wall of the track 990. For example, the extrusion force obtained by the trigger 46 pressing against the inner wall of the main component.

[0136] Figures 22A and 22B show an example of the trigger 46 receiving external force by contacting the lower sidewall 98 of the imaging device. In this embodiment, the direction of movement of the trigger 46 will intersect with the longitudinal direction. The movement process of the contact 44 and the reset 45 is the same as in the above embodiment, and will not be described again here.

[0137] Example 9

[0138] Figure 23 is an exploded view of the first type of limiting member after separation from the processing box housing according to Embodiment 9 of the present invention; Figure 24 is a side view of the processing box having the first type of triggering member according to Embodiment 9 of the present invention viewed in the longitudinal direction; Figures 25A and 25B are state diagrams of the processing box having the first type of triggering member in the imaging device when the contact member according to Embodiment 9 of the present invention is in the blocked state and the exposed state, respectively; Figures 26A and 26B are side views of the processing box having the second type of triggering member viewed in the longitudinal direction when the contact member according to Embodiment 9 of the present invention is in the blocked state and the exposed state, respectively; Figures 27A and 27B are side views of the processing box having the third type of triggering member viewed in the longitudinal direction when the contact member according to Embodiment 9 of the present invention is in the blocked state and the exposed state, respectively.

[0139] The above embodiments describe how the contact 44 is switched / moved from a blocked state to an exposed state in a manner directly controlled by the trigger 46. This embodiment will describe how the contact 44 is switched from a blocked state to an exposed state in a manner indirectly controlled by the trigger 46.

[0140] As shown in Figure 23, in this embodiment, the first end cap 12 also includes a movable member 125 that is movably disposed relative to the end cap body 121. The movable member 125 can move between a first position and a second position. As shown in Figure 24, in the first position, when viewed in the longitudinal direction, the contact member 44 is in a covered state, and the contact portion 443 is covered by the movable member 125 / first end cap 12 and is not exposed. In the second position, when viewed in the longitudinal direction, the contact member 44 is in an exposed state, and the contact portion 443 is no longer covered by the movable member 125 / first end cap 12 and is exposed.

[0141] In some embodiments, the movable element 125 is configured to rotate in the directions shown by R3 and R4 in FIG23, wherein the directions of R3 and R4 are opposite.

[0142] In this embodiment, the movement of the trigger 46 will only cause the movable part 125 to move from the first position to the second position, and will not cause the contact part 44 to move. Therefore, the contact part 44 can be movably set relative to the processing cartridge housing / developing housing 10 / photosensitive housing 20 / first end cap 12 / rotating part, or it can be fixedly set relative to the processing cartridge housing / developing housing 10 / photosensitive housing 20 / first end cap 12 / rotating part. As long as the processing cartridge C is installed in the predetermined position, the contact part 443 can contact the device-side driving part T and suppress the device-side driving part T from retracting to the left.

[0143] In some embodiments, the external force received by the trigger 46 is also the force F from the door cover 97. As shown in FIG24, before the force receiving part 46a receives the force F, the movable part 125 is in the first position. In the longitudinal direction, at least the contact part 443 of the contact member 44 is blocked by the movable part 125, and the contact member 44 / contact part 443 is in the blocked state. When the force receiving part 46a receives the force F, the trigger part 46b transmits the force to the movable part 125, and causes the movable part 125 to rotate to the second position in the direction shown by R3 in FIG24. In the longitudinal direction, at least the contact part 443 of the contact member 44 is not blocked by the movable part 125, and the contact member 44 / contact part 443 is in the exposed state. It can be seen that the contact member 44 in this embodiment can also switch / move between the blocked state and the exposed state, regardless of whether the contact member 44 is movable or fixed relative to the processing cartridge housing / developing housing 10 / photosensitive housing 20 / first end cover 12 / rotating part.

[0144] As shown in Figure 25A, when the processing box C is not yet installed in the predetermined position, under the reset force released by the reset member 45, the contact member 44 / contact portion 443 is in a state where it can contact the device-side drive member T. The movable member 125 is in the first position, and in the longitudinal direction, the contact member 44 / contact portion 443 is blocked by the movable member 125 and is in a blocked state. As shown in Figure 25B, when the processing box C is installed in the predetermined position and the door cover 97 is in the closed state, the contact member 44 / contact portion 443 and the device-side drive member T are in mutual contact. The movable member 125 is triggered by the trigger member 46 and rotates to the second position. In the longitudinal direction, the contact member 44 / contact portion 443 is not blocked by the movable member 125 and is in an exposed state.

[0145] Similar to the above embodiments, the movement of the trigger 46 in this embodiment can be either translational or rotational, as long as it can trigger the movable part 125 to move from the first position to the second position after receiving a force.

[0146] In some embodiments, the movement of the movable member 125 can be in addition to the rotation described above, or it can be translational, as long as it can move between the first position and the second position. Preferably, in order to reset the movable member 125 (from the second position back to the first position), the processing box C may also be provided with a second reset device (not shown) forcing the movable member 125 to reset, and a first reset device for forcing the trigger member 46 to reset.

[0147] As described above, by setting the movable member 125, this embodiment can improve the design freedom of the trigger member 44. Even if the trigger member 44 is set such that when the processing box C is not installed in the predetermined position, the contact member 44 / contact portion 443 is in a state that can contact the device-side drive member T, the contact member 44 / contact portion 443 can be protected by the movable member 125 in the longitudinal direction.

[0148] According to the above embodiments, the trigger for receiving the force F from the door cover 97 in this embodiment can be regarded as a first type of trigger, the trigger for receiving the force from the inner wall 990 of the track can be regarded as a second type of trigger, and the trigger for receiving the force from the inner wall of the main component can be regarded as a third type of trigger. The first type of trigger is represented by A46, the second type of trigger is represented by B46, and the third type of trigger is represented by C46.

[0149] As shown in Figure 26A, the external force received by the second type of trigger B46 (hereinafter referred to as "trigger B46") comes from the inner wall 990 of the track. In one embodiment, the trigger B46 is coaxially arranged with the guided protrusion 14. Therefore, the trigger B46 can also enter the front guide groove 991. With the installation of the processing box C, the trigger B46 receives the external force by contacting the inclined surface 993. At the same time, the trigger B46 drives the movable part 125 to rotate in the direction shown by R3, so that the movable part 125 moves from the first position to the second position. Subsequently, the trigger B46 holds the movable part 125 in the second position by abutting against the inner wall 990 of the track (as shown in Figure 26B).

[0150] In some embodiments, the guide rail 99 further includes an end portion 99d, which is located downstream of the rear guide portion 99c along the installation direction of the processing box C. The end portion 99d is provided with a positioning groove 994 for accommodating the guided protrusion 14. When the processing box C reaches the predetermined position, the guided protrusion 14 is accommodated by the positioning groove 994, and the processing box C is positioned.

[0151] When the processing box C is removed from the imaging device, the trigger B46 no longer abuts against the inner wall 990 of the track, and under the action of the second reset device, the movable part 125 returns from the second position to the first position.

[0152] It should be understood that in the trigger member B46, the part for contacting the inclined surface 993 can be regarded as the force receiving part B46a of the trigger member B46, and the part for driving the moving part 125 can be regarded as the triggering part B46b of the trigger member B46.

[0153] As shown in Figure 27A, the external force received by the third type of trigger C46 (hereinafter referred to as "trigger C46") comes from the inner wall of the main component. For example, the external force received by trigger C46 comes from the lower side wall 98 of the imaging device. Similarly, when the processing box C has not been installed in the predetermined position, trigger C46 cannot receive external force, or the received external force is insufficient to force the movable part 125 to move from the first position to the second position. At this time, as shown in Figure 27A, the movable part 125 is in the first position. When viewed in the longitudinal direction, the contact 44 / contact portion 443 is blocked by the movable part 125 and is in a blocked state. When trigger C46 receives external force, or when the external force received by trigger C46 is sufficient to force the movable part 125 to move from the first position to the second position, as shown in Figure 27B, the movable part 125 reaches the second position. When viewed in the longitudinal direction, the contact 44 / contact portion 443 is not blocked by the movable part 125 and is in an exposed state. That is to say, the contact 44 / contact portion 443 changes from the blocked state to the exposed state.

[0154] Similarly, when the processing box C is removed from the imaging device, the trigger C46 no longer receives external force, and under the action of the second reset device, the movable part 125 returns from the second position to the first position.

[0155] Example 10

[0156] Figure 28A is a perspective view of the processing box according to Embodiment 10 of the present invention when the contact is in a covered state; Figure 28B is a side view of the processing box according to Embodiment 10 of the present invention when the contact is in a covered state, viewed along the longitudinal direction; Figure 29A is a perspective view of the processing box according to Embodiment 10 of the present invention when the contact is in an exposed state; Figure 29B is a side view of the processing box according to Embodiment 10 of the present invention when the contact is in an exposed state, viewed along the longitudinal direction.

[0157] In this embodiment, the movable member 125 and the trigger member 46 are integrally formed. The end of the movable member 125 is the force receiving part 46a of the trigger member 46. This structure not only simplifies the structure of the processing box C, but also improves the transmission efficiency of external force. That is to say, the external force can be directly applied to the movable member 125, so that the movable member 125 can move from the first position to the second position more quickly, which can reduce the possible jamming during the movement of the movable member 125.

[0158] As shown in Figure 28A, along the longitudinal direction, the movable member 125 is located outside the contact member 44 / contact portion 443, or in other words, the movable member 125 is further away from the non-driving side than the contact member 44 / contact portion 443, and the movable member 125 is configured to be able to move in a direction intersecting the longitudinal direction. As shown in Figure 28B, when viewed along the longitudinal direction, the contact member 44 / contact portion 443 is blocked by the movable member 125 and is in a blocked state.

[0159] As the processing box C is installed toward the imaging device, as shown in Figures 29A and 29B, the end of the movable member 125 receives an external force by abutting against the inner wall of the imaging device / device-side drive member T, thereby causing the movable member 125 to move from the first position to the second position. At the same time, the contact member 44 / contact portion 443 changes from a covered state to an exposed state. While the movable member 125 is continuously abutting against the inner wall of the imaging device / device-side drive member T, the contact member 44 / contact portion 443 remains in the exposed state.

[0160] As the processing box C is removed from the imaging device, the movable part 125 no longer abuts against the inner wall of the imaging device / device-side drive part T. Under the action of the first reset device / second reset device, the movable part 125 returns from the second position to the first position, and the contact part 44 / contact portion 443 changes from the exposed state to the blocked state.

[0161] In this embodiment, the movable element 125 can also be an elastic element provided on the end cover body 121. During the installation of the processing box C, the elastic element and the imaging device are pressed against each other to move from the first position to the second position, thereby realizing the transformation / movement of the contact element 44 / contact part 443 from the blocked state to the exposed state.

[0162] Example 11

[0163] Figure 30 is a cross-sectional view taken along the AA direction in Figure 1A; Figure 31 is a side view taken along the longitudinal direction when the processing box according to Embodiment 11 of the present invention is guided by the guide rail; Figure 32 is a perspective view of the processing box according to Embodiment 11 of the present invention when it is installed in a predetermined position of the imaging device.

[0164] As described above, the box-side transmission gear 31 is used to mesh with the equipment-side drive member T to receive the driving force provided by the equipment-side drive member T, thereby causing the rotating member in the processing box C to rotate. However, the processing box C can also receive the driving force in the following ways:

[0165] In one method, the processing box C can also be equipped with a coupling 16 (as shown in Figures 29, 30, 31A, and 31B). This coupling 16 can receive driving force from the device-side drive component T or from a driving force output component separately provided in the imaging device. Then, the coupling 16 transmits the driving force to the rotating component.

[0166] In the second method, the processing box C receives driving force from the driving force output component through the coupling 16, and also receives driving force from the device-side driving component T through the box-side transmission gear 31. The driving force received by the coupling 16 is used to drive the developing roller 11 to rotate, and the driving force received by the box-side transmission gear 31 is used to drive the photosensitive drum 21 to rotate.

[0167] Method 3: The processing box C receives driving force from the driving force output component only through the coupling 16, and then the coupling 16 transmits the driving force to the rotating component.

[0168] In the above-mentioned method three, the contact member 44 abutting against the device-side drive member T will make the overall force on the processing box C more uniform. At this time, the contact member 44 can contact any part of the device-side drive member T. In this embodiment, the contact member 44 is directly disposed on the end cover body 121, or in other words, the contact member 44 is integrally formed with the first end cover 12. Therefore, the contact member 44 is no longer movable relative to the processing box housing / developing housing 10 / photosensitive housing 20 / first end cover 12 / rotating member, but is fixedly disposed, as shown in FIG32. When the processing box C is installed in the predetermined position of the imaging device, the contact member 44 can enter the recess T7 of the device-side drive member T. In the longitudinal direction, at least one of the second main body gear T3 and the step surface T6 contacts the contact member 44, and the bottom surface T71 of the recess T7 can also contact the contact member 44. Thus, the movement of the device-side drive member T in the longitudinal direction can be restricted by the contact member 44.

[0169] In other embodiments, when the processing box C is installed at a predetermined position on the imaging device, the contact member 44 can also contact the outer surface of the main body side rotating shaft T5, the radial outer surface of the first main body side gear T2, the radial outer surface of the second main body side gear T3, and the main body side driving force receiving member T4. This can also restrict the movement of the device side driving member T in the longitudinal direction, and at the same time, make the overall force on the processing box C uniform.

[0170] As shown in Figure 30, when the processing box C is projected along the longitudinal direction, the straight line D passing through the rotation axis L21 of the photosensitive drum 21 and the rotation axis L11 of the developing roller 11 divides the processing box C into a first region S1 and a second region S2, wherein the charging roller 23 is located in the first region S1.

[0171] As shown in Figure 31, when viewed along the longitudinal direction, at least a portion of the contact 44 is located in the S2 region. The guided protrusion 14 overlaps with the photosensitive drum 21, which makes the force on the processing box C more uniform. At least a portion of the guided protrusion 14 is located in the first region S2. With this setting, when the guided protrusion 14 enters the guide rail 99, the entire processing box C is lifted. This not only helps the device-side drive component T to mesh more smoothly with the box-side drive gear 31, but also makes the contact 44 abut more tightly with the device-side drive component T.

[0172] Example 12

[0173] Figure 33 is a state diagram of the processing box and the guide rail after separation according to Embodiment Twelve of the present invention.

[0174] Unlike Embodiment Eleven, the guided protrusion 14 in this embodiment is configured to be movable relative to the processing cartridge housing / developing housing 10 / photosensitive housing 20 / first end cap 12 / rotating member. Specifically, the guided protrusion 14 is configured to be movable in a direction intersecting the longitudinal direction.

[0175] Firstly, this design improves the applicability of the processing box C, ensuring its continued applicability even if the guide rail position in the imaging device deviates.

[0176] Secondly, this design can also improve the ease of installation of the processing cartridge C. Even if the guided protrusion 14 does not enter the guide rail 99, it can eventually enter the guide rail 99 by forcing the guided protrusion 14 to move relative to the processing cartridge housing / developer housing 10 / photosensitive housing 20 / first end cap 12 / rotator.

[0177] Thirdly, during the installation of the processing cartridge C, whether the contact 44 is movable or fixed relative to the processing cartridge housing / developer housing 10 / photosensitive housing 20 / first end cap 12 / rotator, interference between the contact 44 and obstacles in the imaging device can be avoided. The obstacles may be, for example, the device-side drive component T or other interfering components within the imaging device.

[0178] Example Thirteen

[0179] Figure 34 is a perspective view of the processing box according to Embodiment 13 of the present invention when it is installed in a predetermined position on the imaging device; Figure 35 is a perspective view of the accessory according to Embodiment 13 of the present invention; Figures 36A and 36B are perspective views of the accessory according to Embodiment 13 of the present invention when it is in contact with the device-side drive component.

[0180] Unlike the above embodiments, in this embodiment, the limiting component 4 is set as an accessory independent of the processing box C. The accessory can be detachably installed onto the imaging device. The processing box C and the accessory 4 are combined to form a processing box assembly. The user can first install one of the processing box C and the accessory 4 onto the imaging device, and then install the other one onto the imaging device. Through the contact between the accessory 4 and the device-side drive component T, it can still restrict the movement of the device-side drive component T in the longitudinal direction.

[0181] As shown in Figures 34 and 35, the limiting member 4 includes a connecting body 4a, a gripping part 4b, and an actuating part 4c. The gripping part 4b and the actuating part 4c are located at both ends of the connecting body 4a, respectively. Along the installation direction A of the processing box C / limiting member 4, the gripping part 4b, the connecting body 4a, and the actuating part 4c are arranged in sequence. The gripping part 4b is used for the user to grip and operate the limiting member 4. The actuating part 4c is used to abut against the device-side drive member T to limit the movement of the device-side drive member T in the longitudinal direction.

[0182] As described above, since the limiting member 4 is set as an independent component, the limiting member 4 in this embodiment can also be regarded as the contact member 44, the connecting body 4a can be regarded as the contact body 441, the gripping part 4b can be regarded as the force receiving part 442, and the actuating part 4c can be regarded as the contact part 443.

[0183] Continuing as shown in Figure 35, the action part 4c includes a first action block 4c1 and a second action block 4c2. The first action block 4c1 and the second action block 4c2 are respectively used to abut against different parts of the device-side drive member T. As shown in Figures 36A and 36B, after the limiting member 4 is installed on the imaging device, the first action block 4c1 enters the recessed part T7, and the second action block 4c2 abuts against the main body-side drive force receiving member T4, thereby enabling the device-side drive member T to rotate more stably.

[0184] In some embodiments, for the limiting member 4, at least one of the first main body side gear T2, the second main body side gear T3, and the stepped surface T6 abuts against the first actuating block 4c1 in the longitudinal direction, and the right-facing surface of the main body side driving force receiving member T4 abuts against the second actuating block 4c2.

[0185] In some embodiments, the first action block 4c1 may also abut against the bottom surface of the recessed portion T7 to better support the device-side drive component T. The bottom surface of the recessed portion T7 refers to the surface corresponding to the radial projection of the area where the recessed portion T7 is located on the main body-side rotation axis T5 along the axial direction of the main body-side rotation axis T5.

[0186] In this application, the solutions for preventing the device-side drive component T from disengaging in the above embodiments can be combined with each other to make the processing box compatible with a wider variety of device environments, thereby improving the compatibility and practicality of the processing box.

[0187] The beneficial effects that can be obtained by the present invention are as follows:

[0188] 1. The installation of limiting components (such as brake gears) can prevent the equipment-side drive components from disengaging from the box-side transmission components, ensuring the stability of drive force transmission.

[0189] 2. The structure of the limiting components (such as brake gears) in the solution is simplified, which is conducive to the implementation of the solution and also to mass production. In addition, the multiple implementation schemes of the limiting components (such as brake gears) are conducive to the processing box being compatible with a wider variety of equipment environments, thereby improving the compatibility and practicality of the processing box.

[0190] 3. At least a portion of the idler gear is located within the projection surface of the photosensitive drum. This avoids uneven force on the photosensitive drum due to the distance between the rotation axis of the idler gear and the rotation axis of the photosensitive drum being too far apart. In addition, it helps to make the structure of the processing box more compact.

[0191] 4. When the limiting component is set as a protrusion, the brake gear in Embodiment 1 can be omitted, simplifying the solution to prevent the equipment-side drive component from disengaging, making it easier to implement, and also making the structure of the processing box simpler.

[0192] 5. When the box-side transmission gear meshes with the first main body side gear and / or the second main body side gear, the meshing tooth clearance J between the box-side transmission gear and the first main body side gear and / or the second main body side gear is in the range of 0 < J ≤ 0.5 mm, preferably 0.2 mm. This can reduce the movement space of the teeth, making the meshing between the box-side transmission gear and the first main body side gear and / or the second main body side gear tighter, preventing the box-side transmission gear from vibrating, and preventing the equipment-side drive component from disengaging from the box-side transmission gear.

[0193] 7. A limiting element (e.g., an elastic element) is provided on the outer periphery of the box-side transmission gear, or the teeth on the box-side transmission gear are elastic. When the box-side transmission gear meshes with the first main body side gear and / or the second main body side gear, the elastic element or the elastic teeth on the box-side transmission gear are squeezed by the first main body side gear and / or the second main body side gear and undergo elastic deformation, so that the meshing of the box-side transmission gear with the first main body side gear and / or the second main body side gear is tighter, which makes the solution to prevent the equipment-side drive component from disengaging simpler and easier to implement.

[0194] 8. The outer peripheral surface of the limiting component (e.g., idler wheel 43) does not have meshing teeth / protrusions, but is made of materials such as rubber or sponge that can generate friction, so that friction is generated when the idler wheel contacts the first main body side gear and / or the second main body side gear, which can prevent the equipment side drive component from disengaging from the box side transmission gear.

[0195] 9. The contact 44 / contact portion 443 can switch between an obscured position and an exposed position, so that the contact 44 / contact portion 443 is protected from damage before the processing box C is imaged in the imaging device.

[0196] 10. During the installation of the processing box C, the equipment environment provides external force to force the contact part 443 to switch between a shielded state and an exposed state, making the installation process of the processing box C simpler and eliminating the need for manual triggering or other additional installation steps.
