Description

Technical Field

[0001] The utility model relates to a processing box which is used for being detachably installed on a main component of an electronic photographic imaging device. Background Art

[0002] The process cartridge is usually detachably mounted in a main assembly of an electrophotographic imaging device such as a laser printer, a copier, a fax machine, etc. The electrophotographic imaging device uniformly charges an electrophotographic photosensitive member used as an image bearing member, and selectively exposes the electrophotographic photosensitive member. Thus, a latent image is formed. The latent image is then developed by a developer to appear as a developer image. The developer image is then transferred to a recording medium. The developer image transferred to the recording medium is fixed by applying heat and pressure. The image is thus recorded.

[0003] Existing processing boxes are usually equipped with chips, and the contacts on the chip realize communication connection with the electronic photographic imaging device by contacting with contact pins set in the main component of the electronic photographic imaging device, so that the electronic photographic imaging device can obtain information about the processing box, such as whether the processing box is installed, the specifications of the processing box, and other information.

[0004] Patent No. CN105929661B discloses a side member, which is attached to one end face of the process box in the longitudinal direction of the process box, and is provided with a second groove portion 41k. When the process box is installed in the imaging device, the rotation stop ridge 47 is inserted into the second groove portion 41k to limit the position of the process box. In the process box of this structure, the rotation stop ridge 47 often cannot be accurately inserted into the second groove portion 41k, resulting in interference in the installation of the process box, and then causing installation failure.

[0005] Some processing boxes are also provided with a separation force receiving member. When the separation force receiving member receives the separation force, the processing box will be deflected, so there is a risk that the chip and the contact pin will lose electrical contact.

[0047] In the following description, many specific details are explained in combination with embodiments to facilitate a full understanding of the present invention. However, it should be understood that the following embodiments and detailed descriptions are only for illustrative purposes and do not limit the scope of protection of the present invention.

[0048] The structure and working principle of the processing box of the present invention are basically the same as those of the box disclosed in Patent No. CN105929661B, and the same parts are not repeated here. The following only focuses on the main differences between the present invention and the box disclosed in Patent No. CN105929661B.

[0049] Example 1

[0050] Referring to the attached figure of patent specification No. CN105929661B, the processing box is installed in the electronic photographic imaging device in a detachable manner. Specifically, the processing box can be installed to the tray unit along the up and down direction (second direction), and the processing box can be installed to the main body (also called the main component) of the imaging device for forming an image on a recording medium through the tray unit of the electronic photographic imaging device. The processing box is installed on the tray unit and moved in and out of the main body. The tray unit is configured to move together with the processing box along the first direction from a pull-out position located outside the main body to an installation position located inside the main body; the tray unit is provided with a plurality of trays 70, each tray 70 accommodating a processing box 100.

[0051] See the attached patent specification of CN105929661B Fig. 7A and Figure 7B or this application Figure 1AThe imaging device 1 is provided with a rotation stopping protrusion 47 so that the position of the processing box can be restricted when the processing box is installed to the imaging device; specifically, the rotation stopping protrusion 47 is provided in the main body of the imaging device 1.

[0052] The process cartridge may be a developing cartridge including a developing component, a drum cartridge provided with a photosensitive component, or an integrated cartridge having both a developing component and a photosensitive component.

[0053] like Figure 1C , Figure 1D , Figure 2 and Figure 3 As shown, the longitudinal direction of the processing box is defined as X, the vertical direction of the processing box when it is installed in the imaging device is defined as Z, and the direction perpendicular to the longitudinal direction and the vertical direction is defined as Y. The processing box 100 of this embodiment includes a developing unit 1 and a photosensitive unit 2, and the developing unit 1 and the photosensitive unit 2 are connected in a relatively movable manner; specifically, the developing unit 1 and the photosensitive unit 2 are connected by a side member located at the longitudinal end of the processing box 100 X, so that the developing unit 1 and the photosensitive unit 2 can rotate relative to each other; wherein the side member can be a part of the developing unit 1 or the photosensitive unit 2, or can be an independently arranged component; the side member is attached to the longitudinal end of the processing box.

[0054] The developing unit 1 includes a developing component 11, a powder feeding component 12, a first driving member 13, a first conductive member 14 and a first frame 15. The first frame 15 is substantially in the shape of a rectangular parallelepiped. The developing component 11 and the powder feeding component 12 are rotatably arranged on the first frame 15. The powder feeding component 12 faces the developing component 11 so as to be able to transfer the toner contained in the first frame 15 to the developing component 11. The first driving member 13 is arranged at a first end in the longitudinal direction of the process cartridge, and is able to receive a driving force from the electrophotographic imaging device and drive the developing component 11 and the powder feeding component 12 to rotate. The first conductive member 14 is located at a second end opposite to the first end, and is used to supply power to the developing component 11.

[0055] The photosensitive unit 2 includes a photosensitive member 21, a charging member 22, a second driving member 23, a second conductive member 24, and a second frame 25. The photosensitive member 21 and the charging member 22 are rotatably arranged on the second frame 25. The photosensitive member 21 faces the developing member 11 to be able to perform an imaging operation. The developing member 11 is used to supply toner to the photosensitive member 21 so that the electrostatic latent image formed on the surface of the photosensitive member 21 is developed. The charging member 22 is used to charge the photosensitive member 21. The first driving member 13 is arranged at the first end in the longitudinal direction of the process cartridge, and can receive a driving force from the electrophotographic imaging device and drive the photosensitive unit 2 to rotate. The second conductive member 24 is located at the second end opposite to the first end, and is used to supply power to the photosensitive unit 2 or the charging member 22.

[0056] In the following, along the Z direction, the side where the photosensitive component 21 / developing component 11 is provided is the upper side, and the opposite is the lower side; along the X direction, the side where the first driving member 13 / second driving member 23 is provided is the right side, and the opposite is the left side; along the Y direction, the developing unit 1 pointing to the photosensitive unit 2 is the rear side, and the opposite is the front side.

[0057] As shown in Figure 1 to Figure 6 As shown, in this embodiment, the side member is formed as a part of the photosensitive unit 2, which includes a first side member 3 located at the first end of the process box and a second side member 4 located at the second end of the process box, wherein in the present utility model, the first side member 3 and the second side member 4 can both be referred to as side members. The first side member 3 and the second side member 4 are respectively fixedly connected to the two ends of the length direction of the second frame 25 of the photosensitive unit 2, and can be connected to the developing unit 1, so that the developing unit 1 can rotate relative to the photosensitive unit 2.

[0058] like Figure 2 and Figure 3 As shown, the processing box 100 also includes a reset member 17 and a separation force receiving member 6. The reset member 17 and the separation force receiving member 6 are arranged at intervals along the up and down directions. The separation force receiving member 6 is used to receive the separation force from the imaging device to force the developing unit 1 to rotate relative to the photosensitive unit 2 around the rotation axis A1 in the direction shown by r, and the developing component 11 and the photosensitive component 21 reach a mutually separated state from a mutually close state. At the same time, the reset member 17 undergoes elastic deformation to accumulate reset force. When the separation force applied to the separation force receiving member 6 by the imaging device is cancelled, the reset member 17 releases the elastic force, forcing the developing unit 1 to rotate around the rotation axis A1 in the opposite direction of the direction shown by r, and the developing component 11 and the photosensitive component 21 reach a mutually close state again from a mutually separated state, and the processing box 100 can be developed / imaged.

[0059] like Figure 3 and Figure 4 As shown, the first side member 3 is also provided with a chip mounting position 51, a first exposed portion 33a for exposing at least a portion of the first driving member 13, and a second exposed portion 33b for exposing at least a portion of the second driving member 23, so that the first driving member 13 and the second driving member 23 can receive an external driving force. Figure 5As shown, the chip mounting position 51 is arranged on the first main body 32 (as described below) for mounting the chip 31 (storage unit), the chip 31 includes a substrate 311, a terminal 312 mounted on the front side 311a of the substrate, a back side 311b of the substrate opposite to the front side 311a of the substrate, and a side 311c connecting the front side 311a and the back side 311b of the substrate, the terminal 312 is used for electrically contacting with the contact pin in the imaging device to achieve a communication connection between the processing box 100 and the imaging device, and when the processing box is installed in the electronic photographic imaging device, the chip 31 and the chip mounting position 51 are both located on the upper side of the first side member 3, and the front side 311a of the substrate is arranged toward the upper side.

[0060] like Figure 4 As shown, in the up-down direction Z, the first exposed portion 33 a is closer to the chip 31 than the second exposed portion 33 b , and the exposed portion may be a hole structure or a notch structure.

[0061] In this embodiment, the chip mounting position 51 has a mounting surface 511 facing upward, and the chip 31 can be mounted on the mounting surface 511 in a direction perpendicular to the mounting surface 511, and the mounting surface 511 can support the chip 31. Specifically, the chip 31 substrate 311 is mounted on the mounting surface 511 by gluing, and the gluing can be achieved by glue, double-sided tape or sol.

[0062] Furthermore, the direction of the mounting surface 511 is perpendicular to the up-down direction.

[0063] Furthermore, the substrate 311 of the chip 31 is located above the chip mounting position 51, and the side surface 311c of the substrate 311 is exposed to the outside. With this structure of the processing box, the installation and removal of the chip 31 are more convenient, and the chip 31 is not easily damaged.

[0064] The second side member 4 is disposed at the second end of the process box in the longitudinal direction, and includes a third exposed portion 41a and a fourth exposed portion 41b for exposing the first conductive member 14 and the second conductive member 24. The third exposed portion 41a and the fourth exposed portion 41b can be configured as a through hole or a notch structure.

[0065] In some embodiments, the chip mounting position 51 is further provided with a limiting portion to facilitate accurate mounting of the chip 31 .

[0066] In some embodiments, the first exposed portion 33 a and the second exposed portion 33 b are configured as a circular hole structure, and the first exposed portion 33 a and the second exposed portion 33 b have the same size.

[0067] In some embodiments, the first exposed portion 33 a and the second exposed portion 33 b are configured as a circular hole structure, and the radius of the first exposed portion 33 a is smaller than the radius of the second exposed portion 33 b.

[0068] In some embodiments, Figure 6 As shown, the chip 31 also includes a memory 313 arranged on the back side 311b thereof, and the chip mounting position 51 also includes an avoidance groove 512, which is arranged corresponding to the memory 313, and the avoidance groove 512 is formed by being recessed from the mounting surface 511 in a direction away from the chip 31. When the chip 31 is mounted on the mounting surface 511, the memory 313 is located in the avoidance groove 512.

[0069] In some embodiments, the chip mounting position 51 is configured to be detachable relative to the first side member 3, so that when the chip needs to be replaced, the chip can be removed directly by disassembling the chip mounting position 51 without using tools to pry open the chip.

[0070] Example 2

[0071] The difference between this embodiment and embodiment 1 lies in the difference in chip mounting position and chip structure. Figures 7A-7C As shown, the chip mounting position 52 includes a mounting surface 521 and a plurality of mounting protrusions 522 . The mounting surface 521 is used to support the substrate 311 of the chip 31 , and the plurality of mounting protrusions 522 are used to fix the substrate 311 of the chip 31 . The mounting protrusions 522 extend outward in a direction perpendicular to the mounting surface 521 .

[0072] When the chip 31 is mounted on the chip mounting position 52 , the mounting protrusion 522 abuts against a portion of the side surface 311 c of the substrate 311 to restrict movement of the chip 31 .

[0073] Furthermore, the chip mounting position 52 also has a covering portion 523 for fixing the chip 31. In this embodiment, at least one end of the mounting protrusion 522 is provided with a covering portion 523, and the covering portion 523 is located at the end of the mounting protrusion 522 and can cover a portion of the front surface 311a of the substrate 311 to limit the movement of the substrate 311. Specifically, the covering portion 523 can be a structure formed after the end of the mounting protrusion 522 is melted / deformed during the welding process.

[0074] In some embodiments, a through portion 311d penetrating the substrate 311 is further provided on the chip 31 substrate 311. The through portion 311d may be a hole structure or a notch structure. The mounting protrusion 522 is inserted into the through portion 311d and abuts against the side 311c of the chip 31 substrate 311 to limit the movement of the substrate 311.

[0075] When installing the chip 31 of this embodiment, the chip 31 can be first installed on the chip installation position 52 along a direction perpendicular to the installation surface 521, and then the chip 31 can be fixed by welding.

[0076] The processing box of this embodiment reduces the wear on the substrate 311 of the chip 31 when installing the chip 31, and only needs to destroy part of the installation protrusion 522 or the covering part 523 when removing the chip 31, so it is convenient to remove the chip 31.

[0077] Example 3

[0078] The difference between this embodiment and Embodiment 2 lies in the chip mounting position and chip structure.

[0079] like Figure 8-12 As shown, the chip mounting position 53 includes a mounting surface 531, a snap-fitting portion 532 and a covering portion 533. The mounting surface 531 is used to support the chip 31 substrate 311. The covering portion 533 is used to fix the chip 31. The covering portion 533 includes an abutting portion 533a capable of abutting against the front side 311a of the chip 31 substrate and a snap-fitting portion 533b combined with the snap-fitting portion 532. The snap-fitting portion 532 is engaged with the snap-fitting portion 533b of the covering portion 533 to fix the covering portion 533.

[0080] Specifically, the engaging portion 532 and the engaged portion 533b may be configured as a buckle structure.

[0081] When installing the chip 31, the chip 31 can be first installed on the mounting surface 531 in a direction perpendicular to the mounting surface 531, and then the covering portion 533 can be assembled so that the chip 31 is fixedly installed in the chip mounting position 53; the covering portion 533 can be installed in a direction perpendicular to the mounting surface 531 so that the clamping portion 532 is combined with the clamped portion 533b, and can also be installed in a direction parallel to the mounting surface 531.

[0082] With the processing box having the above structure, the installation of the chip is more convenient, and when removing the chip, only the covering part needs to be removed to take it out, thus avoiding damage to the chip installation position 53.

[0083] In some embodiments, Fig.12 As shown, the first side member 3 is provided with a guide groove 34, and the end surface of the developing unit 1 is provided with a protrusion 16 that cooperates with the guide groove 34. The developing unit 1 is supported by the first side member 3 through the cooperation between the guide groove 34 and the protrusion 16. When the developing unit 1 moves relative to the photosensitive unit 2, the protrusion 16 can slide in the guide groove 34. In addition, the first exposed portion 33a is configured as a notch structure, the opening of which faces the direction of movement of the developing unit 2, and the second exposed portion 33b is configured as a circular hole structure, wherein the size of the first exposed portion 33a is larger than the size of the second exposed portion 33b. In a processing box of this structure, when the developing unit 1 moves relative to the photosensitive unit 2, the developing unit 1 can move in the notch structure, and the notch structure provides sufficient displacement space for the developing unit 1. Among them, the above-mentioned guide groove 34 and protrusion 16 can also be applied to other embodiments of the utility model.

[0084] Example 4

[0085] The difference between this embodiment and the first embodiment lies in the different chip mounting positions and chip mounting methods.

[0086] like Figure 13-14 As shown, the chip mounting position 54 includes a mounting cavity 542, a mounting surface 541 located in the mounting cavity 542 for supporting the substrate 311 of the chip 31, and a covering portion 543 located above the mounting surface 541 for fixing the chip 31. The mounting cavity 542 is adapted to the substrate 311 of the chip 31, and has a mounting entrance 544, which faces the upper side of the processing box, and the substrate 311 of the chip 31 can be installed in the mounting cavity 542 through the mounting entrance 544 along a direction perpendicular to the mounting surface 541.

[0087] Further, the side surface 311 c of the chip substrate 311 can be wrapped by the mounting cavity 542 .

[0088] Furthermore, the installation entrance 544 has an installation guide portion 545; when the chip is installed in the installation cavity, the guide portion 545 plays a role in guiding the chip to be installed smoothly.

[0089] When installing the chip 31 , the chip 31 can be pressed into the installation cavity 542 through the installation entrance 544 , which makes assembly easier.

[0090] Example 5

[0091] The difference between this embodiment and the aforementioned embodiment 4 lies in the different chip mounting positions and chip mounting methods.

[0092] like Fig.15 As shown, along the X direction or the Y direction, an elastic component 546 is provided on at least one side of the mounting cavity 542, and the elastic component 546 includes a covering portion 543, and the covering portion 543 is located at the end of the elastic component 546. When the chip 31 is installed in a direction perpendicular to the mounting surface, the elastic component 546 elastically deforms to allow the chip 31 to be installed in the mounting cavity 542, and the covering portion 543 abuts against the front side 311a of the substrate of the chip 31 to limit the position of the chip 31. In the chip mounting position of this structure, the chip can be pressed into the chip mounting position to achieve installation, and its structure is simple and easy to install.

[0093] Specifically, the elastic component 546 can be configured as an elastic hook, and the covering portion 543 extends toward the inside of the installation cavity 542. The number of the elastic hooks can be one or more; preferably, the elastic component 546 is configured as two, and along the X direction of the process cartridge 100 or the direction Y perpendicular to the X direction and the direction Z of the process cartridge 100, the two elastic components are respectively located on both sides of the installation cavity 542.

[0094] Example 6

[0095] like Fig.16 As shown, this embodiment makes further improvements on the second side member 4 based on the previous embodiment, that is, the second side member 4 of this embodiment can be applied to the processing box of the previous embodiment.

[0096] Combination Figure 1A , Fig.16 The second side member 4 has a first end face 41 and a step portion 42 protruding from the first end face 41 along the longitudinal direction. The first end face 41 faces away from the developing unit 1 / first frame 15 along the longitudinal direction X. The step portion 42 abuts against the rotation stop ridge 47 when the process cartridge is loaded into the electrophotographic imaging device and the door cover is closed, so that the position of the process cartridge is limited. Specifically, the step portion 42 has an abutting surface 421 facing the lower side of the process cartridge. The abutting surface 421 is located on the upstream side of the second conductive member 24 along the first direction P (parallel to the Y direction), and the abutting surface 421 abuts against the rotation stop ridge 47 of the electrophotographic imaging device; in other words, the abutting surface 421 is located behind the second conductive member 24.

[0097] Further, the step portion 42 includes a recessed portion 422, which is recessed from the step portion 42 toward the direction of the first end of the process cartridge along the X direction of the process cartridge, and is recessed from the first direction P. Preferably, the second conductive member 24 is located in the recessed portion 422; preferably, the second conductive member 24 is exposed along the direction opposite to the first direction P; which is conducive to the installation of the second conductive member 24. The first direction P is preferably parallel to the Y direction. This structural design can avoid interference between the step portion and the rotation stop protrusion 47 during the process of installing the process cartridge into the electronic photographic imaging device. In particular, when the door cover is closed, it can ensure that the abutting surface 421 smoothly abuts against the rotation stop protrusion 47.

[0098] Example 7

[0099] like Fig.17 As shown, the chip mounting position 55 in this embodiment is also provided with an elastic component 556 and a covering portion 553 located at the end of the elastic component 556. When the chip 31 is installed toward the mounting cavity 557 in a direction perpendicular to the mounting surface 551, the elastic component 556 is elastically deformed to allow the chip 31 to be installed, and the covering portion 553 abuts against the front side 311a of the substrate of the chip 31 to limit the chip 31.

[0100] Furthermore, the chip mounting position 55 also includes a blocking portion (mounting protrusion) 552 arranged on a different side from the elastic portion 556. When the chip 31 is mounted to the mounting surface 551, the blocking portion 552 and the elastic portion 556 both abut against the side surface 311c of the substrate, so that the chip 31 can be stably positioned on the mounting surface 551. Therefore, the blocking portion 552 and the elastic portion 556 can be collectively referred to as a limiting portion, which abuts against the side surface 311c of the substrate to limit the movement of the chip 31 in a direction perpendicular to the Z direction.

[0101] Preferably, two elastic components 556 are provided, and along the longitudinal direction X or Y, the two elastic components 556 are respectively located on both sides of the mounting cavity 557; in some embodiments, only one of the two elastic components 556 may be elastic. Fig.17 An example is given in which two elastic components 556 are respectively arranged on both sides of the installation cavity 557 along the longitudinal direction X. In a deformable manner, the two elastic components 556 can also be respectively arranged on both sides of the installation cavity 557 along the Y direction.

[0102] by Fig.17 Taking the structure shown as an example, the blocking portion 552 is arranged on the Y direction side of the mounting cavity 557. Preferably, two blocking portions 552 are also provided, and the two blocking portions are arranged on opposite sides of the mounting cavity 557. Along the Y direction, the two blocking portions (two mounting protrusions) 552 are arranged at intervals. In one embodiment, the two blocking portions 552 are staggered. Specifically, the blocking portion 552 includes a first blocking portion 552a located behind the mounting cavity 557 and a second blocking portion 552b located in front of the mounting cavity 557. Along the longitudinal direction X, the extending dimensions of the first blocking portion 552a and the second blocking portion 552b are both smaller than the dimensions of the mounting cavity 557. Therefore, a gap 550 is formed adjacent to the first blocking portion 552a and the second blocking portion 552b, that is, along the arrangement direction of the two elastic components 556, or along the direction intersecting with the arrangement direction of the two blocking portions, in the area S defined by the mounting cavity 557, a gap 550 is arranged adjacent to the blocking portion 552.

[0103] like Fig.18As shown, the first blocking portion 552a is located on the left side of the second blocking portion 552b. Along the longitudinal direction X, the first blocking portion 552a has a first end surface 552c located at the right end and a second end surface 552d located at the left end. The second blocking portion 552b has a third end surface 552e located at the right end and a fourth end surface 552f located at the left end. A first reference line L1 parallel to the Y direction is made through the rightmost point / surface of the first blocking portion 552a. The first reference line L1 is at least located on the left side of the third end surface 552e. Preferably, the first reference line L1 is located on the left side of the fourth end surface 552f or the first reference line L1 passes through the fourth end surface 552f. In this preferred embodiment, the first blocking portion 552a and the second blocking portion 552b do not overlap in the Y direction, the structure of the chip mounting position 55 will become simple, and the mold for making the chip mounting position 55 will be easier to demold.

[0104] In some embodiments, along the longitudinal direction X, the first blocking portion 552a and the second blocking portion 552b can also exchange positions, that is, the first blocking portion 552a is located on the right side of the second blocking portion 552b. At this time, the first reference line L1 will pass through the leftmost point / surface of the first blocking portion 552a, and along the longitudinal direction X, the first reference line L1 is at least located on the right side of the fourth end surface 552f. Preferably, the first reference line L1 is located on the right side of the third end surface 552e or the first reference line L1 passes through the third end surface 552e.

[0105] In some embodiments, the blocking portion 552 and the elastic component 556 may be interchanged, that is, the elastic component 556 is disposed on the Y direction side of the installation cavity 557 , and the blocking portion 552 is disposed on the longitudinal X direction side of the installation cavity 557 .

[0106] The imaging device further includes a preventing portion disposed in the main body, and the existing processing cartridge is further provided with a U-shaped groove portion for cooperating with the preventing portion, the U-shaped groove being disposed on the side member, and when the tray unit is moved into the main body and the processing cartridge moves downward with the tray unit, the preventing portion enters the U-shaped groove portion to position the processing cartridge in the imaging device. For example, the patent US8862022B2 Figure 8 or in this application Figure 1B As shown, the imaging device further includes a preventing portion 53b disposed in the main body, and the existing processing box is further provided with a U-shaped groove portion 24b for cooperating with the preventing portion 53b, and the U-shaped groove 24b is disposed on the side member. When the tray unit is moved into the main body, and the processing box moves downward with the tray unit, the preventing portion 53b enters the U-shaped groove portion 24b to position the processing box in the imaging device. However, the positioning structure needs to accurately align the preventing portion 53b with the U-shaped groove 24b, otherwise, the tray unit will not be able to move downward smoothly, and there is even a risk of damaging the imaging device or the processing box.

[0107] To this end, the present invention also cuts off the U-shaped groove 24b to form an escape portion 37, such as Fig.17 As shown, along the Y direction, the avoidance portion 37 is arranged behind the chip mounting position 55, and when the processing box 100 involved in the utility model moves down to the predetermined position along with the tray unit, the preventing portion 53 in the imaging device enters the avoidance portion, or in other words, the preventing portion 53 is exposed along the Y direction; in some embodiments, the U-shaped groove 24 may also be retained, but when the processing box 100 involved in the utility model moves down to the predetermined position along with the tray unit, the avoidance portion 37 still enters the U-shaped groove 24, but no matter how the processing box is subjected to force in the imaging device, the preventing portion 53 does not contact the side wall forming the U-shaped groove 24, that is, the U-shaped groove 24 is no longer combined with the preventing portion 53 to play a role in positioning the processing box 100.

[0108] Example 8

[0109] Different from the embodiment 7, the first blocking portion 552a and the second blocking portion 552b in this embodiment are arranged to overlap along the Y direction or along the longitudinal direction X. Specifically, along the Y direction or along the longitudinal direction X, the entirety of one of the first blocking portion 552a and the second blocking portion 552b overlaps with the other. Fig.19 As shown, the first blocking portion 552a and the second blocking portion 552b are respectively located on both sides of the Y direction of the mounting cavity 557. Along the Y direction, the first blocking portion 552a and the second blocking portion 552b overlap, and a second reference line L2 parallel to the Y direction is made through the leftmost point / surface of the first blocking portion 552a. The second reference line L2 will pass through the leftmost point / surface of the second blocking portion 552b, and along the longitudinal direction X, the extended dimension of the first blocking portion 552a does not exceed the extended dimension of the second blocking portion 552b, or the extended dimension of the second blocking portion 552b does not exceed the extended dimension of the first blocking portion 552a.

[0110] In some embodiments, the second reference line L2 may not pass through the leftmost point / surface of the second blocking portion 552b. Overall, along the longitudinal direction X, as long as the first blocking portion 552a does not exceed the area formed by the leftmost point / surface and the rightmost point / surface of the second blocking portion 552b extending along the Y direction, it will be sufficient. In other words, along the longitudinal direction X, as long as the second blocking portion 552b does not exceed the area formed by the leftmost point / surface and the rightmost point / surface of the first blocking portion 552a extending along the Y direction.

[0111] According to the above description, the structure of the chip mounting position 55 in this embodiment becomes simple, and the mold for making the chip mounting position 55 is also easier to demold.

[0112] Example 9

[0113] As described in reference patent CN105929661B, the imaging device is provided with a tray unit capable of carrying a process cartridge, the tray unit is provided with a plurality of trays 70, each tray 70 accommodating a process cartridge. Fig. 20 The structure of the tray 70 is shown. As shown in the figure, the tray 70 includes a tray frame 79 and a supporting portion 75 arranged on the tray frame 79, and the supporting portion 75 is used to support the processing box; specifically, the tray frame 79 includes a first side plate 71, a second side plate 72, a third side plate 73 and a fourth side plate 74, wherein the first side plate 71 and the second side plate 72 are arranged opposite to each other at intervals along the Y direction, and the third side plate 73 and the fourth side plate 74 are arranged opposite to each other at intervals along the longitudinal direction X, and the first side plate 71, the second side plate 72, the third side plate 73 and the fourth side plate 74 are enclosed to form a processing box accommodating chamber 76, and along the Y direction, the first side plate 71 is located in front of the second side plate 72, and the first side plate 71 has a first inner surface 711 facing the processing box accommodating chamber 76, and the second side plate 72 has a second inner surface 721 facing the processing box accommodating chamber 76, and the first inner surface 711 and the second inner surface 721 are arranged opposite to each other.

[0114] like Fig.21 As shown, the first side member 3 includes a first body 32 and a first supported portion 34 and a second supported portion 35 provided on the first body 32, a first exposed portion 33a and a second exposed portion 33b are provided on the first body 32, and the second side member 4 includes a second body 46 and a third supported portion 44 and a fourth supported portion 45 provided on the second body 46, as shown in FIG. Fig.16 As shown, the third exposed portion 41 a and the fourth exposed portion 41 b are disposed on the second body 46 .

[0115] When the tray unit is moved out of the main body, the first supported portion 34 and the third supported portion 44 are supported by the supporting portion 75 at the same time, so that the process cartridge 100 is supported in the process cartridge installation cavity 76. When the tray unit is moved into the main body, the second supported portion 35 and the fourth supported portion 45 are supported by the positioning portion in the main body (such as the reference patent US8862022B2). Figure 8 Or this application Figure 1B 51a and 52a) support.

[0116] like Figure 2 and Figure 3 As shown, when the separation force receiving member 6 receives the separation force, as the developing unit 1 rotates, the side member or the developing unit will be subjected to a forward thrust, and at the same time, the elastically deformed reset member 17 will apply a backward thrust to the second frame 25. For this reason, the processing box 100 is also required to be provided with a positioning member for positioning the processing box 100 in the processing box mounting cavity 76. The positioning member positions the processing box 100 by overcoming the forward thrust and / or backward thrust.

[0117] As described above, the developing unit 1 is arranged to rotate relative to the photosensitive unit 2 , and preferably, a positioning member is provided in at least one of the side member and the second frame 25 .

[0118] like Fig.21 and Fig. 22 As shown, the positioning members in this embodiment include a first positioning member 81 and a third positioning member 83 arranged on the first side member 3 and a second positioning member 82 and a fourth positioning member 84 arranged on the second side member 4. Along the Y direction, the first positioning member 81 and the third positioning member 83 are arranged at intervals, and the second positioning member 82 and the fourth positioning member 84 are arranged at intervals. Along the longitudinal direction X, the first positioning member 81 and the second positioning member 82 are arranged at intervals, and the third positioning member 83 and the fourth positioning member 84 are arranged at intervals.

[0119] Along the Y direction, the first main body 32 has a first front surface 36a facing forward and a first rear surface 36b facing rearward, and the second main body 32 has a second front surface 43a facing forward and a second rear surface 43b facing rearward, respectively. The first positioning member 81 is formed by protruding forward from the first front surface 36a, and the third positioning member 83 is formed by protruding backward from the first rear surface 36b. Preferably, each of the positioning members is formed as a protrusion, which can be fixed or movably arranged.

[0120] like Fig.23 As shown, after the processing box 100 is installed in the processing box installation cavity 76, the first positioning member 81 and the second positioning member 82 are simultaneously opposite to the first inner surface 711, and the third positioning member 83 and the fourth positioning member 84 are simultaneously opposite to the second inner surface 721. In general, the first positioning member 81 and the second positioning member 82 can be referred to as front positioning members, and the third positioning member 83 and the fourth positioning member 84 can be referred to as rear positioning members, that is, the front positioning member includes at least one of the first positioning member 81 and the second positioning member 82, and the rear positioning member includes at least one of the third positioning member 83 and the fourth positioning member 84; preferably, before the separation force receiving member 6 receives the separation force, the front positioning member and the first inner surface 711 are in a state of contact with each other, or a gap is formed between the front positioning member and the first inner surface 711, so as to facilitate the smooth installation of the processing box 100. Similarly, the rear positioning member and the second inner surface 721 also have one of the above two states.

[0121] Along the longitudinal direction X, each positioning member in this embodiment can abut against the tray frame 79 at both ends of the process box 100, so that the force applied to the process box 100 is more uniform.

[0122] When the separation force receiving member 6 receives the separation force, under the action of the forward thrust and the backward thrust, the front positioning member abuts against the first inner surface 711, and the rear positioning member abuts against the second inner surface 721. In this way, the second frame 25 and the side member can be stably positioned in the processing box mounting cavity 76. Even if the developing unit 1 rotates relative to the photosensitive unit 2, the position of the processing box 100 in the processing box mounting cavity 76 will not change, and the risk of the terminal 312 being out of electrical contact with the contact pin can be eliminated.

[0123] In some embodiments, the various positioning members do not need to be formed in a protruding manner, but can be formed by increasing the size of the side member along the Y direction. In this case, the entire first front surface 36a can be regarded as the first positioning member 81, the entire first rear surface 36b can be regarded as the third positioning member 83, the entire second front surface 43a can be regarded as the second positioning member 82, and the entire second rear surface 43b can be regarded as the fourth positioning member 84.

[0124] In some embodiments, the processing box 100 also includes a bracket / side plate arranged between the first frame 15 / second frame 25 and the side member, and the bracket / side plate is used to support the rotatable components in the processing box (photosensitive component 21, charging component 22, developing component 11, powder feeding component 12, first driving member 13, second driving member 23, etc.). Based on the inventive concept of the present utility model, the positioning member can also be arranged on the bracket / side plate. Generally, the bracket / side plate is fixedly connected to the second frame 25, and therefore, the bracket / side plate can also be regarded as a part of the photosensitive unit 2 / second frame 25.

[0125] Example 10

[0126] like Fig.24 and Fig.25 As shown, the rear positioning member in this embodiment is a protrusion 75 arranged on the second frame 25, and the front positioning member 81 / 82 is still arranged on the side member.

[0127] In some embodiments, the protrusion 75 is disposed at a substantially middle position of the second frame 25 along the longitudinal direction X, and the first positioning member 81, the second positioning member 82, and the protrusion 75 are arranged in a triangle, so that when the separation force receiving member 6 receives the separation force, the process cartridge 100 can be stably positioned. That is, the connecting line of the first positioning member 81, the second positioning member 82, and the protrusion 75 is in a triangle.

[0128] In some embodiments, along the longitudinal direction X, there may be two protrusions 75 spaced apart from each other, which can also play a role in stably positioning the process box 100 .

[0129] Although the present invention is described above through embodiments, it should be understood that the above embodiments are only used to exemplarily describe the feasible implementation methods of the present invention, and should not be interpreted as limiting the scope of protection of the present invention. That is, any replacement or change made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection of the claims of the present invention.
