Description

Technical Field

[0001] The present invention relates to the technical field of electronic imaging equipment, and in particular to a processing box. Background Art

[0002] Existing processing boxes are generally provided with a memory on the box body, and the memory is mainly used to record basic information of the processing box, such as the model of the electronic imaging device that the processing box is suitable for, the number of prints, the toner reserve remaining, the service life, etc.

[0003] As a method for fixing the memory on the box, various methods are known: for example, there is a method of fixing the memory to the frame of the box by double-sided tape, etc., which is effective when the area of ​​the joint surface can be ensured to be relatively large. In addition, a method of directly fixing the memory by insert molding is known. There is also a method in which the frame of the box is provided with an opening and a guide, and then the memory is slidably inserted and installed on the frame through the opening. In this method, the memory is fixed to the box by forming a retaining portion (limiting the movement of the memory in the thickness direction) and a preventing portion (limiting the movement of the memory in the insertion direction). The memory can be fixed to the box well by the above methods, but these methods are not conducive to the removal or replacement of the memory. For example, when the memory fixed on the box is damaged or the memory needs to be replaced due to reasons such as firmware upgrades, the memory in the above method is restricted by the retaining portion and the preventing portion, so the memory cannot be directly taken out, resulting in difficulty in removing the memory and inconvenience in replacing.

[0055] Embodiment 1

[0056] The electronic imaging device forms an image on a recording material using, for example, an electronic photographic imaging process box. The electronic imaging device includes an electronic photographic copier, an electronic photographic printer (LED printer, laser printer, etc.), an electronic photographic printer-type fax machine, etc. The process box is detachably mounted in the electronic imaging device, and the process box includes a photosensitive member, a developing member for developing an electrostatic latent image formed on the photosensitive member, etc. The electronic imaging device includes a drive head, which is used to transmit the driving force of the electronic imaging device to the process box to operate the process box.

[0057] like Figure 1 As shown, this embodiment provides a processing box, including a frame, a powder bin assembly, a waste powder bin assembly, a driving unit and a storage 40.

[0058] like Figure 1 As shown, the frame includes a developing frame 10 and a photosensitive frame 20. The powder bin assembly includes a powder bin for storing toner, a developing roller, a powder knife, and a stirring frame installed in the powder bin. The waste toner bin assembly includes a waste toner bin for collecting waste toner, a photosensitive drum, a charging roller, and a cleaning blade.

[0059] like Figure 1 As shown, the developing frame 10 forms a powder bin for storing toner. The developing frame 10 is roughly in the shape of a long box, and the developing frame 10 has end faces at both ends in the length direction. The developing frame 10 may be provided with a powder adding port, through which toner is added to the powder bin, and the powder adding port may be opened on one of the end faces of the developing frame 10. The stirring frame and the developing roller are rotatably supported at both ends in the length direction of the developing frame 10. The stirring frame and the developing roller can rotate under the action of the driving unit, and the axial directions of the stirring frame and the developing roller are along the length direction of the developing frame 10. The toner in the powder bin is stirred by the stirring frame to prevent the toner in the powder bin from agglomerating, and the toner can also be transported toward the developing roller to be adsorbed by the charged developing roller.

[0060] like Figure 1 As shown, the photosensitive frame 20 forms a waste toner bin for collecting waste toner. The photosensitive frame 20 also has a length direction, which is consistent with the length direction of the developing frame 10. The photosensitive drum is rotatably supported at both ends of the photosensitive frame 20 in the length direction, and the axial direction of the photosensitive drum is consistent with the length direction of the photosensitive frame 20.

[0061] In order to better explain the processing box, Figure 1 A coordinate system is established in which the axial direction of the photosensitive drum is the X-axis direction, the direction perpendicular to the axial direction X of the photosensitive drum is the Y-axis direction, and the direction perpendicular to the X-axis and Y-axis directions is the Z-axis direction. The X-axis direction is also the length direction of the process box, the Y-axis direction is also the width direction of the process box, and the Z-axis direction is also the height direction (thickness direction) of the process box. The plane formed by the X-axis and the Y-axis is the XY plane, the plane formed by the Y-axis and the Z-axis is the YZ plane, and the plane formed by the X-axis and the Z-axis is the XZ plane.

[0062] The driving unit is located outside the end surface in the length direction of the frame, and can be specifically arranged outside one or two end surfaces of the developing frame 10 in the length direction, or outside one or two end surfaces of the photosensitive frame 20 in the length direction. The driving unit is used to receive and transmit the driving force of the electronic imaging device to make the processing box work. The driving unit can include a power receiving member and a gear set, so as to receive and transmit the driving force of the electronic imaging device, and drive the photosensitive drum, the developing roller, the stirring frame, etc. to rotate.

[0063] Further, such as Figure 1As shown, the frame may further include an end cap 30, which is disposed outside the end face of the photosensitive frame 20 in the length direction and also covers a portion of the developing frame 10, and covers a portion or all of the gears of the driving unit in the end cap 30 for protection. The end cap 30 may be integrally disposed with the photosensitive frame 20, or may be a separate structure, and may be fixedly mounted on the photosensitive frame 20 by welding, pasting, snapping, plugging or other means. Alternatively, the end cap 30 may be integrally disposed with the developing frame 10 or may be fixedly mounted on the developing frame 10.

[0064] like Figure 1 and Figure 2 As shown, the memory 40 can be a chip, and the memory 40 has a substrate, which is roughly rectangular, with the length direction of the substrate extending along the X-axis direction, the width direction of the substrate extending along the Y-axis direction, and the thickness direction of the substrate extending along the Z-axis direction. The substrate is divided into two regions roughly along the center position in the length direction, namely, the first region 41 on the +X-axis side and the second region 42 on the -X-axis side, and the width of the second region 42 is greater than the width of the first region 41. The memory has an outer surface and an inner surface in the thickness direction, the outer surface faces the +Z-axis direction, and the inner surface faces the -Z-axis direction. A storage unit is provided on the substrate, and the storage unit is configured to store information related to the processing box. An electrical contact 43 (communication terminal) is also provided on the outer surface (surface on the +Z-axis side) of the memory 40 in the thickness direction, and the storage unit is electrically connected to the electrical contact 43. The number of the electrical contacts 43 is two, and the two electrical contacts 43 are arranged at intervals along the length direction of the memory 40 (i.e., arranged in the X-axis direction), and the two electrical contacts 43 are both located in the region of the memory 40 on the +X-axis side (i.e., in the first region 41). When the memory 40 is installed in the process box, the electrical contact 43 is arranged to face away from the process box, that is, the electrical contact 43 faces the +Z axis direction. When the process box is installed in the electronic imaging device, the electrical contact 43 is electrically connected to the contact pin of the electronic imaging device, thereby establishing communication between the memory 40 and the electronic imaging device, and the electronic imaging device can read the information in the storage unit.

[0065] like Figure 2 As shown, in this embodiment, the memory 40 is installed on the frame, and specifically can be installed on the end cover 30. The upper end surface (the end surface on the +Z axis side) of the end cover 30 is provided with a downwardly recessed installation groove 31, and a memory installation portion 50 is provided in the installation groove 31. The memory installation portion 50 includes a supporting portion 51 and a limiting portion 52.

[0066] like Figure 3 and Figure 4 As shown, the support portion 51 is used to support the memory 40. The support portion 51 is a boss-like structure protruding from the bottom of the mounting groove 31. The electrical contacts 43 of the memory 40 are placed on the support portion 51 and supported by it with the electrical contacts 43 facing upward (i.e., the outer surface of the memory 40 faces the +Z axis direction).

[0067] like Figures 2 to 4 As shown, the limiting portion 52 is located at the periphery of the memory 40, and is used to limit the movement of the memory 40 in the width direction and the length direction. In this embodiment, the limiting portion 52 includes a plurality of protrusions 52a, preferably four protrusions 52a, which are respectively located at the four corners of the rectangular substrate of the memory 40, and each protrusion 52a is respectively in contact with a corner of the memory 40 to form a restriction on the length direction and the width direction of the memory 40. The protrusion 52a can be a cylindrical protrusion, and its axial direction extends along the Z-axis direction. The protrusion 52a is provided with a recess 52a1 that matches the angle of the memory 40. The recess 52a1 is a right-angled notch formed on the protrusion 52a. When the recess 52a1 is in contact with the corner of the memory 40, it is also in contact with the two right-angled sides of the corner, so that the effect of limiting both the length direction and the width direction can be achieved. In some other embodiments, the number of the protrusions 52 a of the limiting portion 52 may be greater, for example, protrusions 52 a abutting against the side walls of the memory 40 may be provided on both sides of the memory 40 in the width direction.

[0068] When the memory 40 is installed in the memory installation portion 50 , the support portion 51 is located below the memory 40 to support the memory 40 , and the restriction portion 52 is located on the periphery of the side wall of the memory 40 to restrict its movement in the width direction and the length direction.

[0069] Preferably, the support portion 51 and the limiting portion 52 may be an integrally formed structure, and are integrally formed on the end cover 30, and the limiting portion 52 may be formed on the surface of the support portion 51 (which may be a side surface or a top surface), and together form a memory mounting portion 50 that can support and limit the memory 40 in the +X, -X, +Y, -Y, and -Z axis directions. In some other embodiments, the support portion 51 and the limiting portion 52 may also be integrally formed and disposed on the photosensitive frame 20.

[0070] Preferably, the outer surface (+Z axis end surface) of the limiting portion 52 is lower than the outer surface (+Z axis end surface) of the memory 40, and the limiting portion 52 does not limit the memory 40 in the thickness direction. The memory 40 can be installed or removed along the thickness direction. The memory 40 is installed on the supporting portion 51 along the -Z axis direction and removed from the supporting portion 51 along the +Z axis direction, thereby solving the current technical problems of the difficult disassembly and inconvenience in replacing the memory 40. When the memory 40 needs to be replaced, the memory 40 can be easily disassembled and replaced.

[0071] Furthermore, since the limiting portion 52 does not limit the memory 40 in the thickness direction, in order to prevent the memory 40 from falling off along the thickness direction, an adhesive layer (such as an adhesive, double-sided tape, etc.) can be set between the supporting portion 51 and the inner surface of the memory 40 (the surface in the -Z axis direction) to adhere the memory 40 to the supporting portion 51, thereby limiting the memory 40 from detaching from the +Z axis direction.

[0072] Furthermore, if Figure 4 As shown, a buffer 60 may be provided between the support portion 51 and the memory 40. The buffer 60 may be a sponge layer (or other elastic member, such as a silicone block, etc.), so that the memory 40 has a movable amount in the thickness direction, and can play a buffering role when the stylus of the electronic imaging device contacts the electrical contact 43, thereby preventing the stylus and the electrical contact 43 from being damaged by collision. The buffer 60 may be pasted on the support portion 51, and an adhesive layer may be provided on the +Z axis side surface of the buffer 60 to adhere to the inner surface of the memory 40, thereby preventing the memory 40 from detaching from the +Z axis direction.

[0073] like Figures 1 to 4 As shown, when the memory 40 needs to be replaced, the two side walls of the memory 40 (which can be the two side walls in the length direction or the two side walls in the width direction) can be clamped by a clamping tool (such as tweezers), and force can be applied in the +Z axis direction to destroy the adhesion between the memory 40 and the adhesive layer. The memory 40 can be removed from the support portion 51 along the +Z axis direction, and then the new memory 40 (which can be the removed memory 40 after firmware upgrade, or it can be another brand new memory 40) can be installed on the support portion 51 along the -Z axis direction. The operation is simple and quick.

[0074] Embodiment 2

[0075] This embodiment provides another processing box, which is different from the first embodiment in that the structure of the limiting portion 52 is different.

[0076] like Figures 5 to 7As shown, in this embodiment, the limiting portion 52 is a rib abutting against the periphery of the memory 40, and the limiting portion 52 is integrally arranged with the supporting portion 51, that is, the rib is protruding from the surface of the supporting portion 51. Specifically, the limiting portion 52 includes a first rib 52b, a second rib 52c, a third rib 52d and a fourth rib 52e. The length of the first rib 52b extends along the X-axis direction, and the length of the first rib 52b is equivalent to the length of the memory 40. The first rib 52b abuts against one side of the width direction of the memory 40 (specifically, the +Y direction side). The length of the second rib 52c extends along the Y-axis direction, and the length of the second rib 52c is equivalent to the width of the memory 40. The second rib 52c abuts against one side of the length direction of the memory 40 (specifically, the -X direction side), and one end of the second rib 52c can be connected to one end of the first rib 52b to form a right angle structure. The length of the third rib 52d extends along the X-axis direction, and the length of the third rib 52d matches the length of the first area 41 of the memory 40. The third rib 52d abuts against the -Y-axis side of the first area 41 of the memory 40. There is a gap between one end of the third rib 52d in the -X-axis direction and one end of the second rib 52c in the -Y-axis direction to form a notch position, and the portion of the second area 42 of the memory 40 with a width greater than that of the first area 41 is embedded in the notch position. The fourth rib 52e is arranged opposite to the second rib 52c, and the fourth rib 52e abuts against the other side (the +X-axis side) of the length direction of the memory 40. The length of the fourth rib 52e is less than that of the second rib 52c, and both ends of the fourth rib 52e are not connected to the first rib 52b and the third rib 52d.

[0077] The outer surfaces (+Z-axis side surfaces) of all the ribs of the limiting portion 52 are lower than the outer surface (+Z-axis side surface) of the memory 40, and will not limit the memory 40 in the thickness direction (Z-axis direction). The multiple ribs surrounding the memory 40 only limit the movement of the memory 40 in the length and width directions. When the memory 40 needs to be replaced, it can still be disassembled or installed along the thickness direction, which is convenient to operate.

[0078] In this embodiment, the limiting portion 52 and the supporting portion 51 are integrally formed and arranged on the end cover 30 or the photosensitive frame 20 .

[0079] The other structures of the processing box of this embodiment are the same as those of the first embodiment and will not be described again.

[0080] Embodiment 3

[0081] This embodiment provides another processing box, which is different from the second embodiment in that the structure of the limiting portion 52 is different.

[0082] like Figures 8 to 10As shown, in this embodiment, the limiting portion 52 includes a first part and a second part 52f, wherein the first part is integrally formed on the frame, and the first part includes a plurality of ribs, and the plurality of ribs surround the memory 40. The structure of the plurality of ribs is the same as that of the second embodiment. Specifically, the first part includes a first rib 52b, a second rib 52c and a fourth rib 52e, the first rib 52b abuts against the +Y axis side of the memory 40, the second rib 52c abuts against the -X axis side of the memory 40, and the fourth rib 52e abuts against the +X axis side of the memory 40. In this embodiment, the second rib 52c is integrally formed on the photosensitive frame 20, and the first rib 52b and the fourth rib 52e are integrally formed on the end cover 30. The support portion 51 is also divided into two parts, one part is integrally formed with the second rib 52c and arranged on the photosensitive frame 20, and the other part is integrally formed with the fourth rib 52e and arranged on the end cover 30. The support portion 51 located on one side of the photosensitive frame 20 can be used to support the second area 42 of the storage device 40, and the support portion 51 located on one side of the end cover 30 can be used to support the first area 41 of the storage device 40.

[0083] Optionally, the first portion of the limiting portion 52 may be integrally formed on one of the photosensitive frame 20 or the end cover 30 , and the supporting portion 51 may be integrally formed on one of the photosensitive frame 20 or the end cover 30 .

[0084] like Figures 8 to 10 As shown, the limiting part 52 of this embodiment is different from that of the second embodiment in that a second part 52f is provided on the -Y axis side of the storage device 40 to replace the third rib 52d. Specifically, the second part 52f is constructed to be able to move relative to the frame to cooperate with other ribs to clamp the storage device 40. The second part 52f can move along the width direction (Y axis direction). The second part 52f is a splint-like structure that is rotatably arranged on the end cover 30. A rotating shaft 52f1 is provided on one side of the second part 52f. The axis of the rotating shaft 52f1 extends along the X axis direction. The bottom of the installation groove 31 is provided with a rotating groove 311 that is concave downward. The rotating groove 311 is adapted to the rotating shaft 52f1. The rotating shaft 52f1 is embedded in the rotating groove 311 and can rotate in the -Y axis or +Y axis direction with the rotating shaft 52f1 as the axis. The second part 52f rotates in the +Y axis direction to press against the -Y axis side of the storage device 40, and limits the movement of the storage device 40 in the Y axis direction together with the first rib 52b.

[0085] Further, such as Figures 8 to 10As shown, the processing box further includes an elastic member 70, which is respectively in contact with the frame and the second part 52f, thereby providing the second part 52f with a force to clamp the storage device 40. Specifically, the elastic member 70 is a torsion spring, and a pillar 32 for mounting the torsion spring is provided on the end cover 30, and the pillar 32 extends along the X-axis direction. The coil of the torsion spring is sleeved on the pillar 32, and one arm of the torsion spring is in contact with the end cover 30, and the other arm is in contact with the -Y-axis side of the second part 52f. The torsion spring is configured to always apply a force toward the +Y-axis direction to the second part 52f, so that the second part 52f can clamp the storage device 40 under the action of the elastic force to prevent it from being separated.

[0086] The surface of the outer surface (+Z axis direction) of the limiting portion 52 can be lower than or higher than the outer surface of the memory 40. In this embodiment, the outer surfaces of the first rib 52b and the second rib 52c in the first part are higher than the outer surface of the memory 40, the outer surface of the fourth rib 52e is lower than the outer surface of the memory 40, and the outer surface of the second part 52f (clamp) is higher than the outer surface of the memory 40. The first rib 52b and the second part 52f are higher than the outer surface of the memory 40, which can make the limiting portion 52 clamp the memory 40 more stably in the Y axis direction.

[0087] In some other embodiments, the outer surface of the limiting portion 52 may also be lower than the outer surface of the memory 40, or the outer surface of the limiting portion 52 may be flush with the outer surface of the memory 40, or some ribs in the first part of the limiting portion 52 may be flush with the memory 40, and other ribs may be lower than the memory 40.

[0088] When the memory 40 needs to be replaced, force can be applied to make the second part 52f (clamp) move in the direction away from the memory 40 (-Y axis direction), and then the two side walls of the memory 40 (which can be the two side walls in the length direction or the two side walls in the width direction) are clamped by a clamping tool (such as tweezers), and force is applied in the +Z axis direction. The memory 40 is removed from the support part 51 along the +Z axis direction, and then a new memory 40 (which can be the removed memory 40 after firmware upgrade, or it can be another brand new memory 40) is installed in the limiting part 52 along the -Z axis direction. The force on the second part 52f is removed, and the second part 52f moves in the +Y axis direction under the action of the elastic member 70 and clamps the memory 40. The operation is simple and quick.

[0089] In some other embodiments, the first rib 52b may be omitted and replaced by a rotatable clamping plate, that is, the limiting of the -Y axis side and the +Y axis side of the storage part are both achieved by the movable clamping plate.

[0090] In some other embodiments, the movable clamp (the second part 52f) can also be set on one side or both sides of the length direction of the storage device 40, that is, the movable clamp moves in the length direction to clamp the storage device 40, and can also achieve a limiting effect on the storage device 40.

[0091] The other structures of the processing box of this embodiment are the same as those of the first embodiment and will not be described again.

[0092] Embodiment 4

[0093] This embodiment provides a processing box, which is different from the third embodiment in that the structure of the limiting portion 52 is different.

[0094] like Fig.11 and Fig.12 As shown, in this embodiment, the limiting portion 52 includes a first part that is fixedly arranged and a second part that is movably arranged, and the first part includes a second rib 52c and a fourth rib 52e, and the second rib 52c and the fourth rib 52e are respectively abutted against the -X axis side and the +X axis side of the memory 40.

[0095] like Figures 11 to 13 As shown, the second part includes a first clamp plate 52g and a second clamp plate 52h, and the first clamp plate 52g and the second clamp plate 52h are both located in the XZ plane. The first clamp plate 52g and the second clamp plate 52h are respectively clamped on the -Y axis side and the +Y axis side of the memory 40, and the first clamp plate 52g and the second clamp plate 52h are both movable along the Y axis direction. An elastic member 70 is provided between the first clamp plate 52g and the end cover 30, and an elastic member 70 is also provided between the second clamp plate 52h and the end cover 30. The elastic member 70 provides a force for the first clamp plate 52g and the second clamp plate 52h to clamp the memory 40. Specifically, the end cover 30 is provided with a slide bar 33, the first clamping plate 52g and the second clamping plate 52h are provided with a slide hole 52i sleeved on the slide bar 33, the slide bar 33 extends along the Y-axis direction, the first clamping plate 52g and the second clamping plate 52h are movably arranged on the slide bar 33 through the slide hole 52i, and the movement direction of the first clamping plate 52g and the second clamping plate 52h is limited by the slide bar 33. The elastic member 70 can be a compression spring, which is also sleeved on the slide bar 33, and its two ends abut between the end cover 30 and the clamping plate.

[0096] like Figures 11 to 13As shown, the first clamping plate 52g includes a first tooth portion 52g1, which is arranged on one side of the first clamping plate 52g in the +X axis direction, and the first tooth portion 52g1 extends along the Y axis direction; the second clamping plate 52h includes a second tooth portion 52h1, which is arranged on one side of the second clamping plate 52h in the -X axis direction, and the second tooth portion 52h1 extends along the Y axis direction. The first tooth portion 52g1 and the second tooth portion 52h1 are opposite to each other in the X axis direction and there is a gap between them. The end cover 30 is also provided with a gear 80, which is rotatably arranged in the mounting groove 31 of the end cover 30, and the rotation axis of the gear 80 extends along the Z axis direction. The first tooth portion 52g1 and the second tooth portion 52h1 are both meshed with the gear 80. The meshing of the tooth portions with the gear 80 enables the first clamping plate 52g and the second clamping plate 52h to be linked, that is, to clamp the storage 40 at the same time or to release the clamping of the storage 40 at the same time.

[0097] like Figures 11 to 13 As shown, when the memory 40 needs to be replaced, a force can be applied to the first clamping plate 52g in a direction away from the memory 40. After the force is applied, the first clamping plate 52g moves in a direction away from the memory 40, and the first tooth portion 52g1 that moves accordingly drives the gear 80 to rotate. When the gear 80 rotates, it drives the second tooth portion 52h1 that meshes with it to move, thereby causing the second clamping plate 52h to also move in a direction away from the memory 40, that is, the first clamping plate 52g and the second clamping plate 52h both release their grip on the memory 40, and then the two sides of the memory 40 are clamped by a clamping tool (such as tweezers). The first clamping plate 52g and the second clamping plate 52h move toward the direction close to the memory 40 and clamp the memory 40 under the force of the elastic member 70, and the operation is simple and quick. Of course, when replacing, a force can also be applied to the second clamping plate 52h to keep it away from the memory 40.

[0098] like Fig.12 As shown, in this embodiment, the gear 80 and the tooth portion can also serve as a part of the support portion 51 to support the storage 40, especially the first area 41 of the storage 40, and the outer surfaces of the gear 80 and the tooth portion are flush.

[0099] In this embodiment, the outer surfaces of the first clamp plate 52g and the second clamp plate 52h are flush with the outer surface of the memory 40, the outer surface of the second rib 52c is higher than the outer surface of the memory 40, and the outer surface of the fourth rib 52e is flush with the outer surface of the memory 40. The fourth rib 52e is a frame-like structure, and the vacant part on the inner side thereof can reserve space for the first tooth portion 52g1 to move.

[0100] In some other embodiments, the movable first clamp 52g and the second clamp 52h may also be arranged on both sides of the length direction of the storage 40, that is, the movable clamp moves in the length direction to clamp the storage 40, and can also achieve a limiting effect on the storage 40.

[0101] The other structures of the processing box of this embodiment are the same as those of the first embodiment and will not be described again.

[0102] Embodiment 5

[0103] This embodiment provides another processing box, which is different from the first embodiment in that the structure of the end cover 30 is different.

[0104] like Fig.14 and Fig.15 As shown, in this embodiment, a mounting groove 31 is provided on the end cover 30 for setting a memory mounting portion 50. In the Y-axis direction, the memory mounting portion 50 is located approximately in the middle of the mounting groove 31. A first rib 37 is also provided in the mounting groove 31. The first rib 37 is located on the -Y-axis side of the memory mounting portion 50. The first rib 37 extends along the Y-axis direction. The first rib 37 is connected to the groove wall of the mounting groove 31 and the side wall of the -Y-axis side of the memory mounting portion 50 at both ends in the Y-axis direction.

[0105] like Fig.14 and Fig.15 As shown, in this embodiment, the top surface of the end cover 30 in the +Z axis direction includes a first surface 35 and a second surface 36, wherein the top surface of the end cover 30 located on the -Y axis side of the mounting groove 31 is the first surface 35, and the top surface located on the +Y axis side of the groove 34 is the second surface 36. The height of the first surface 35 is roughly equivalent to the height of the first rib 37. The first surface 35 and the first rib 37 together constitute a first pressed portion. When the processing box is installed in the electronic imaging device, the pressing portion in the electronic imaging device moves in the -Z axis direction and presses the first pressed portion, so that the position of the processing box is fixed, and the contact pin in the electronic imaging device can stably contact the electrical contact 43 of the memory 40.

[0106] like Fig.14 and Fig.15As shown, in this embodiment, a groove 34 is further provided on the end cover 30. The groove 34 is formed by the groove bottom of the mounting groove 31 being recessed downward. The groove 34 is located on the +Y axis side of the memory mounting portion 50, and the -Y axis side of the groove 34 is flush with the +Y axis side of the memory mounting portion 50. The +Y axis side of the groove 34 is the second surface 36. The height of the groove bottom of the groove 34 is lower than the height of the second surface 36. The height of the second surface 36 is lower than the height of the first surface 35. When the process cartridge is installed in the electronic imaging device, when the pressing portion moves in the -Z axis direction to press the first pressed portion, the groove 34 and the second surface 36 do not contact the pressing portion, that is, the pressing portion only presses the first pressed portion to position the process cartridge.

[0107] The end cover 30 of the present embodiment is provided with a first pressed portion only on one side of the memory mounting portion 50, and a second surface 36 and a groove 34 whose height is lower than the first surface 35 and the first rib 37 are provided on the other side, which is equivalent to having only one pressed portion on the end cover 30 and omitting the pressed portion on the other side, thereby saving materials and space, and being conducive to the miniaturization of the processing box.

[0108] The other structures of the processing box of this embodiment are the same as those of the first embodiment and will not be described again.

[0109] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
