Description

Technical Field

[0001] This utility model relates to the field of electrophotographic imaging, and more particularly to a processing box that can be detachably installed in an electrophotographic imaging device. Background Technology

[0002] There is a processing box that can be detachably installed into an imaging device. The processing box has two positioning parts at one longitudinal end. During the installation and removal of the processing box, the two positioning parts are guided by the guide rails in the imaging device. This requires the two positioning parts to be aligned with the corresponding guide rails at the same time. This makes it impossible for the user to install the processing box into the device in one go. The user needs to try multiple times to install it in place, resulting in a poor user experience.

[0003] Furthermore, the processing box also includes a chip component that makes electrical contact with the stylus of the imaging device to achieve communication between the processing box and the imaging device. When the processing box is installed, the contact part of the chip component and the stylus need to maintain stable communication contact. However, the stylus of the imaging device is a triangular metal plate. Because the electrical contact area between the tip of the stylus's free end and the contact part is too small, it is easily affected by the vibration generated by the operation of the processing box, resulting in poor contact between the stylus and the contact part or even interruption of electrical contact. As a result, the imaging device reports an error or stops operating, affecting the user's experience. Utility Model Content

[0006] A recessed portion is located on one side of the processing box; a first unit includes a first unit housing and a photosensitive element; a second unit is combined with the first unit, the second unit includes a second unit housing and a developing element, the photosensitive element and the developing element are arranged opposite to each other; a chip assembly includes a contact portion that makes electrical contact with the stylus, the contact portion being used to establish a communication connection with the imaging device;

[0007] The processing box has a driving side on one side where the recess is provided, and a non-driving side on the opposite side. The non-driving side is provided with a third guided part and a fourth guided part. When viewed along the longitudinal direction of the processing box, the line segment connecting the third guided part and the fourth guided part does not intersect with the straight line perpendicular to the contact part and passing through the contact part.

[0008] Furthermore, the two endpoints of the line segment are the centers of the third and fourth guiding parts, respectively.

[0009] Furthermore, the chip assembly also includes a chip and a support portion for supporting the chip, the support portion being coupled to the first unit housing / second unit housing; the chip includes a substrate and a contact portion disposed on the substrate.

[0010] Furthermore, the stylus includes a first intersection line located at the free end of the stylus, wherein the direction in which the substrate faces the first intersection line is the front, and the direction opposite to the front is the rear; the direction intersecting the front-back direction is the up-down direction; the direction intersecting the front-back direction and the up-down direction is the left-right direction, and the left-right direction is parallel to the longitudinal direction; during the assembly of the processing box, the chip approaches from behind the stylus.

[0011] Furthermore, the stylus includes a side surface that intersects with the first intersection line, and the contact portion makes electrical contact with the side surface of the electrical stylus.

[0012] Furthermore, the substrate includes a third portion located above, a first portion located below, a fourth portion located to the left, and a second portion located to the right, the first portion, the second portion, the third portion, and the fourth portion enclosing to form a contact cavity; at least a portion of the contact portion is located in the contact cavity.

[0013] Furthermore, the substrate includes at least one of a third portion located above, a first portion located below, a fourth portion located to the left, and a second portion located to the right forming a contact cavity, the contact cavity having an opening; at least a portion of the contact portion is located in the contact cavity.

[0014] Furthermore, the contact portion is configured to be inclined relative to the front-back direction.

[0015] Furthermore, the contact portion is configured to be arc-shaped.

[0016] Furthermore, the contact portion is movable relative to the substrate.

[0017] The beneficial effects of this utility model are:

[0018] The processing box with the above structure, when viewed along the longitudinal direction of the processing box, has a line segment connecting the third guided part and the fourth guided part that does not intersect with the straight line perpendicular to the contact part and passing through the contact part, thus limiting the angle of the contact part facing the stylus, thereby increasing the electrical contact area between the contact part and the stylus. When the processing box is in the installed state, the processing box can maintain a stable communication connection with the imaging device, and the user experience can be improved.

[0040] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0041] [Imaging equipment]

[0042] Figure 1A and Figure 1B This is a three-dimensional view of the internal structure of the imaging device involved in this utility model.

[0043] To more clearly describe the structure of the processing box and its movement within the imaging device, we will first combine... Figure 1A and Figure 1B The imaging device H100 has a first sidewall H101 and a second sidewall H102 arranged opposite each other in the Y direction. A receiving space H116 for accommodating a processing box is formed between the first sidewall H101 and the second sidewall H102. The first sidewall H101 is provided with a first guide rail H1012 and a third guide rail H115 for guiding the processing box, and the second sidewall H102 is provided with a second guide rail H103 and a fourth guide rail H105 for guiding the processing box. The guide rail H111 is provided with at least two guide rails, wherein the first guide rail H1012 and the second guide rail H103 are respectively provided with at least two guide rails. Along the Y direction, the third guide rail H115 is closer to the second side wall H102 than the first guide rail H1012, and the fourth guide rail H111 is closer to the first side wall H101 than the second guide rail H103. That is to say, along the Y direction, the distance between the third guide rail H115 and the fourth guide rail H111 is less than the distance between the first guide rail H1012 and the second guide rail H103.

[0044] Furthermore, the imaging device also includes a driving force output component H114 disposed on one of the first sidewall H101 and the second sidewall H102, the driving force output component H114 being used to output driving force to the processing box to drive the rotating component in the processing box to rotate.

[0045] With the direction A that the user faces when installing or removing the processing box as a reference, the accommodating space H116 has adjacent inclined surfaces H112 and horizontal surfaces H113 (which can be collectively referred to as the inner wall of the imaging device). Inclined surface H112 is inclined relative to direction A, and horizontal surface H113 is parallel to direction A. The third guide rail H115 is closer to the inclined surface H112 / horizontal surface H113 than the first guide rail H1012, and the fourth guide rail H111 is closer to the inclined surface H112 / horizontal surface H113 than the second guide rail H103. The processing box is installed along the X direction towards the accommodating space H116. During the installation process, the processing box first passes through the inclined surface H112 and then reaches the horizontal surface H113. Finally, the processing box is positioned above the horizontal surface H113.

[0046] [Processing Box]

[0047] Figure 2A and Figure 2B This is a perspective view of the processing box involved in this utility model.

[0048] The processing cartridge 100 extends along the Y direction and is mounted along the X direction, which can be referred to as the longitudinal direction of the processing cartridge 100. As shown in the figure, the processing cartridge 100 includes a first unit 10 and a second unit 20 connected to each other. The first unit 10 includes a first unit housing 11 and a photosensitive element 13 rotatably disposed in the first unit housing 11. The rotation axis L1 of the photosensitive element 13 is parallel to the longitudinal direction Y. The second unit 20 includes a second unit housing 21 and a developing element 22 rotatably disposed in the second unit housing 21. The rotation axis L2 of the developing element 22 is parallel to the longitudinal direction Y. The developing element 22 is arranged opposite to the photosensitive element 13 and is used to transport unused toner stored in the second unit housing 21 to the photosensitive element 13, thereby developing the electrostatic latent image formed on the surface of the photosensitive element 13.

[0049] Furthermore, the processing box 100 also includes a handle 12 connected to the first unit housing 11 / second unit housing 21, through which the user can easily pick up the processing box 100.

[0050] The longitudinal end of the photosensitive element 13 is also provided with a first driving assembly for receiving and / or transmitting driving force. This first driving assembly can be a single component or two components, such as... Figure 2AAs shown, the first driving assembly includes a first driving force receiver 15 for receiving driving force and a driving force transmitter 14 for transmitting driving force. The first driving force receiver 15 is combined with the driving force output member H114 to receive driving force, and the driving force transmitter 14 is used to transmit driving force to the developing member 22.

[0051] The longitudinal end of the developing element 22 is also provided with a second driving component 23 for receiving and / or transmitting driving force. The second driving component may be one component or two components.

[0052] In some embodiments, the first driving force receiver 15 and the second driving component 23 receive driving forces from the imaging device, thereby driving the photosensitive element 13 and the developing element 22 to rotate respectively. In this embodiment, the imaging device can be provided with two driving force outputs, so that the first driving force receiver 15 and the second driving component 23 are driven respectively, or the imaging device can be provided with one driving force output, so that the first driving force receiver 15 and the second driving component 23 are simultaneously driven by the driving force output.

[0053] In some embodiments, one of the first driving force receiver 15 and the second driving component 23 receives driving force from the imaging device and then the driving force is transmitted to the second driving component 23 by the driving force transmitter 14, or the driving force is transmitted to the driving force transmitter 14 by the second driving component 23. In this embodiment, the first driving component and the second driving component 23 can be disposed on the same side of the processing box 100 or on opposite sides of the longitudinal direction of the processing box 100.

[0054] like Figure 2A As shown, the processing box 100 is also provided with a recess 100a for receiving the driving force output component. Along the longitudinal direction Y, the recess 100a is adjacent to the photosensitive element 13. The second driving component 23 or the third driving component 231 in the second unit for combining with the second driving component 23 is exposed through the recess 100a. The third driving component 231 is used to drive at least one of the components such as the powder feeding component and the stirring component located in the second unit 20 to rotate. The stirring component is used to stir the toner, and the powder feeding component contacts the developing element 22 and is used to transport the toner toward the developing element 22.

[0055] Along the longitudinal direction Y, the side with the recessed portion 100a is designated as the driving side F, and the side opposite to the driving side F is designated as the non-driving side E. In the following description, the example in which both the first driving component and the second driving component 23 are provided on the driving side F will be used.

[0056] Continue as Figure 2A and Figure 2BAs shown, the first unit 10 also includes a first unit driving side end piece 11F located on the driving side F and a first unit non-driving side end piece 11E located on the non-driving side E. The second unit 20 also includes a second unit driving side end piece 21F located on the driving side F and a second unit non-driving side end piece 21E located on the non-driving side E. The first unit driving side end piece 11F and the first unit non-driving side end piece 11E are integrally or separately formed with the first unit housing 11. Similarly, the second unit driving side end piece 21F and the second unit non-driving side end piece 21E are integrally or separately formed with the second unit housing 21. When the separate form is adopted, the first unit driving side end piece 11F, the first unit non-driving side end piece 11E, the second unit driving side end piece 21F and the second unit non-driving side end piece 21E will be combined with the corresponding housing in the form of end caps.

[0057] Regardless of the form, the first driving-side end member 11F and the second driving-side end member 21F are respectively located at one longitudinal end of the first unit housing 11 and the second unit housing 21, and the first non-driving-side end member 11E and the second non-driving-side end member 21E are respectively located at the other longitudinal end of the first unit housing 11 and the second unit housing 21. Therefore, the first driving-side end member 11F and the second driving-side end member 21F can be collectively referred to as the driving-side end member of the processing box 100, and the first non-driving-side end member 11E and the second non-driving-side end member 21E can be collectively referred to as the non-driving-side end member of the processing box 100. The first unit 10 and the second unit 20 are connected to each other through the driving-side end member and the non-driving-side end member.

[0058] Furthermore, the processing box 100 also includes a first guided portion 100F1 and a second guided portion 100F2 disposed on the driving-side end member, and a third guided portion 100E1 and a fourth guided portion 100E2 disposed on the non-driving-side end member. Specifically, each guided portion can be formed as a protrusion or a groove, as long as it can be combined with and guided by the corresponding guide rail in the imaging device. As shown in the figure, the first guided portion 100F1 is a protrusion disposed on the driving-side end member 11F of the first unit, the second guided portion 100F2 is a protrusion disposed on the driving-side end member 21F of the second unit, and the third guided portion 100E1 and the fourth guided portion 100E2 are both protrusions disposed on the non-driving-side end member 11E of the first unit. Through the third guided portion 100E1 and the fourth guided portion 100E2, the first unit 10 is positioned in the imaging device.

[0059] In some embodiments, the drive force output member 14 is configured to move between a vertical state and an inclined state. Before the processing box 100 is installed in the predetermined position of the imaging device, the drive force output member 14 is in an inclined state. At this time, the rotation axis of the drive force output member 14 is inclined relative to the rotation axis L1 of the photosensitive element 13. As the processing box 100 is installed, the drive force output member 14 gradually moves towards the vertical state. When the processing box 100 is installed in the predetermined position of the imaging device, the drive force output member 14 reaches the vertical state. At this time, the rotation axis of the drive force output member 14 is coaxial with or parallel to the rotation axis L1 of the photosensitive element 13. For this purpose, the processing box 100 is also provided with a straightening member 16 for forcing the drive force output member 14 to move from the inclined state to the vertical state.

[0060] In some embodiments, the processing box 100 further includes a chip assembly 30 for establishing a communication connection with an imaging device. The chip assembly 30 includes a chip 32 and a support portion 31 for supporting the chip 32. The support portion 31 is combined with a first unit housing 11 or a second unit housing 21. Preferably, the support portion 31 is integrally formed with the first unit housing 11 or the second unit housing 21. At least a portion of the chip 32 is supported by the support portion 31. Specifically, at least the contact portion 322 of the chip 32 for electrical contact with the imaging device (e.g., ...) Figure 3 (As shown) is supported by support 31. In some embodiments, support 31 is detachable from the first unit housing 11 or the second unit housing 21.

[0061] Preferably, the contact portion 322 is planar and is not located on the same side as the first driving component / second driving component 23, so as to reduce the impact of vibration generated by the first driving component / second driving component 23 on the contact portion 322 during imaging of the processing box 100. In the figure, the contact portion 322 is located on the non-driving side E.

[0062] (Chip Components)

[0063] As described above, chip 32 is used to make electrical contact with the stylus in the imaging device to establish a communication connection with the imaging device. The structure of chip 32 is described below.

[0064] The first type of chip

[0065] Figure 3 This is a perspective view of the first type of chip in this utility model; Figure 4 This is a partial schematic diagram of the first type of chip in electrical contact with the contact pin in this utility model; Figure 5 This is a schematic diagram showing the contact between the processing box with the first type of chip and the stylus when viewed along the longitudinal direction.

[0066] The chip 32 includes a substrate 321 and a contact portion 322 disposed on the substrate. Depending on the number of pins, the contact portion 322 is configured to be at least one. The pin 9 is configured as a triangular metal sheet, including a first conductor 91 and a second conductor 92 intersecting at the tip 93. The first conductor 91 and the second conductor 92 can be formed separately or integrally. The space between them can be filled with a filler or form a void 94.

[0067] The first conductor 91 has a first contact surface 911 that does not face the second conductor 92, and the second conductor 92 has a second contact surface 921 that does not face the first conductor 91. The first contact surface 911, the second contact surface 921, and the tip 93 can all contact the contact portion 322 to achieve electrical contact between the chip 32 and the stylus. The first contact surface 911 and the second contact surface 921 intersect at a first intersection line 931. The first intersection line 931 is the free end of the stylus 9 and is part of the tip 93. Preferably, the first intersection line 931 is the end line of the tip 93. In some embodiments, the first contact surface 911 and the second contact surface 921 are connected by an arc surface located at the end of the tip 93. In this case, the stylus 9 and the contact portion 322 can also be regarded as forming a line contact. The projection of the contact line of the two on the arc surface is the first intersection line 931. In this case, the first contact surface 911 and the second contact surface 921 will each include a part of the arc surface and intersect at the first intersection line 931.

[0068] When the substrate 321 abuts against the first intersection line 931, the direction in which the substrate 321 faces the tip 93 is the front, or the direction opposite to the direction in which the tip 93 enters the contact cavity 323 is the front, the direction opposite to the front is the rear, and the direction intersecting the front-back direction is the up-down direction. The first conductor 91 is located above the second conductor 92, and the direction intersecting the front-back direction and the up-down direction is the left-right direction. The left-right direction is parallel to the longitudinal direction Y. The side where the driving side F is located is the left, and the side where the non-driving side E is located is the right. Preferably, the front-back direction, the up-down direction, and the left-right direction are orthogonal. In this coordinate system, during the installation of the processing box 100, the chip 32 approaches the contact pin 9 from behind.

[0069] Overall, the stylus 9 also has a third contact surface 95 facing to the left and a fourth contact surface 96 facing to the right. That is, the third contact surface 95 and the fourth contact surface 96 are arranged opposite each other in the longitudinal direction, and the fourth contact surface 95 and the fourth contact surface 96 also intersect with the first intersection line 931.

[0070] like Figure 3As shown, the substrate 321 includes a first portion 3211 located at the bottom, a second portion 3212 located on the right, a third portion 3213 located at the top, a fourth portion 3214 located on the left, and a contact cavity 323 located above the first portion 3211. The first portion 3211, the second portion 3212, the third portion 3213, and the fourth portion 3214 enclose and form the contact cavity 323. At least a portion of the contact portion 322 is located in the contact cavity 323. The contact cavity 323 has an opening 323a facing forward / to the stylus 9. The stylus 9 can enter the contact cavity 323 through the opening 323a.

[0071] Specifically, a support surface 321a is provided in the contact cavity 323, and at least a portion of the contact portion 322 is located on the support surface 321a. In this embodiment, the support surface 321a is configured to be perpendicular to the vertical direction and face upward. Therefore, at least a portion of the contact portion 322 is also perpendicular to the vertical direction and faces upward. More specifically, the contact portion 322 also has a second intersection line 3221 that intersects with the first portion 3211.

[0072] like Figure 4 and Figure 5 As shown, when the processing box 100 is installed, the opening 323a faces the stylus 9, at least a portion of the end portion 93 enters the contact cavity 323, and the second contact surface 921 contacts the second intersection line 3221. That is, the chip 32 / contact portion 322 and the stylus 9 form a line contact. Compared with the way the first intersection line 931 contacts the contact portion 322, the second contact surface 921 has a larger area that can contact the contact portion 322. The chip 32 / contact portion 322 and the stylus 9 will form a more stable electrical contact. On the other hand, the second contact surface 921 can also apply a downward pressing force to the chip 32 through the second intersection line 3221 to prevent the processing box 100 from moving upward. Thus, the electrical contact stability between the chip 32 / contact portion 322 and the stylus 9 is further enhanced.

[0073] In some embodiments, the contact portion 322 may also extend to the first portion 3211, making the electrical contact between the stylus 9 and the contact portion 322 more stable and increasing the amount of contact.

[0074] The second type of chip

[0075] Figure 6A This is a schematic diagram showing the contact between the processing box with the second type of chip and the stylus when viewed along the longitudinal direction.

[0076] Based on the above inventive concept, in this embodiment, the contact portion 322 is still disposed in the contact cavity 323, but the contact portion 322 / support surface 321a is configured to be inclined relative to the front-back direction.

[0077] like Figure 6A As shown, the second contact surface 921 contacts the contact portion 322. At this time, the stylus 9 forms a surface contact with the chip 32 / contact portion 322. Obviously, compared with the above-mentioned line contact method, the surface contact in this embodiment is more conducive to maintaining a stable electrical contact between the chip 32 / contact portion 322 and the stylus 9. Moreover, the surface contact formed between the stylus 9 and the chip 32 / contact portion 322 makes the pressing pressure applied by the stylus 9 to the chip 32 / contact portion 322 more even, and the processing box can be held more stably in the imaging device. Correspondingly, the electrical contact stability between the chip 32 / contact portion 322 and the stylus 9 is further enhanced.

[0078] Continue as Figure 6A As shown, the third guided part 100E1 has a center M, and the fourth guided part 100E2 has a center N. The line connecting the center M and the center N forms a line segment MN. The straight line C1 is perpendicular to the support surface 321a / contact part 322 and passes through the support surface 321a / contact part 322. The straight line C1 does not pass through the line segment MN, that is, the straight line C1 does not intersect with the line segment MN.

[0079] The third type of chip

[0080] Figure 6B This is a schematic diagram showing the contact between the processing box with the third type of chip and the stylus when viewed along the longitudinal direction.

[0081] Similar to the second type of chip, the contact portion 322 in this embodiment is still disposed in the contact cavity 323, and the connecting portion 322 / support surface 321a is still set to be inclined relative to the front-back direction. However, the contact portion 322 contacts the first contact surface 911. Therefore, the inclination direction of the contact portion 322 / support surface 321a in this embodiment is different from the inclination direction of the contact portion / support surface in the above embodiment.

[0082] In this embodiment, the straight line that is perpendicular to the support surface 321a / contact portion 322 and passes through the support surface 321a / contact portion 322 is C2. The straight line C2 does not pass through the line segment MN, that is, the straight line C2 does not intersect with the line segment MN.

[0083] Similar to the first type of chip, the contact portion 322 can also be configured to form a line contact with the first contact surface 911.

[0084] Depending on the structure of the second and third chips, in some embodiments, the contact portion 322 may also be disposed on the surface of the contact cavity 323 facing the second portion 3212 or the fourth portion 3214. The contact portion 322 contacts the third contact surface 95 or the fourth contact surface 96. In this case, the surface is the support surface of the contact portion 322. The straight line perpendicular to the support surface / contact portion 322 and passing through the support surface / contact surface 322 does not pass through the line segment MN, but is parallel to the longitudinal direction.

[0085] The first contact surface 911, the second contact surface 921, the third contact surface 95 and the fourth contact surface 96 can be collectively referred to as the side surface of the stylus 9, and the chip 32 / contact portion 322 can be configured to contact the side surface.

[0086] The fourth type of chip

[0087] Figure 7 This is a perspective view of the fourth type of chip in this utility model.

[0088] Similar to the first type of chip, the chip 32 in this embodiment still includes a substrate 321 and a contact portion 322 disposed on the substrate 321. The substrate 321 forms a contact cavity 323, and the contact portion 322 is located in the contact cavity 323. Specifically, at least one contact portion 322 is disposed on a support surface 321a. The support surface 321a / contact portion 322 is perpendicular to the vertical direction and faces upward.

[0089] In this embodiment, the substrate 321 does not have a third part 3213, that is, an opening at the top of the contact cavity 323. In this way, the stylus 9 can smoothly enter the contact cavity 323, and the positional accuracy requirement of the chip 32 / substrate 321 can be reduced.

[0090] Furthermore, the second portion 3212 or the fourth portion 3214 of the substrate 321 can also be omitted, making the left or right side of the contact cavity 323 open. This design allows the stylus 9 to enter the contact cavity 323 more smoothly and further reduces the positional accuracy requirements of the chip 32 / substrate 321.

[0091] Based on the inventive concept of the above embodiments, the structure of the substrate 321 can be further simplified as follows: the fourth part 3214 is also omitted, and the space above the first part 3211 can be regarded as the contact cavity 323; or, the contact part 322 is disposed on the third part 3213, in which case the first part 3211, the second part 3212 and the fourth part 3214 are all omitted, and the space below the third part 3213 can be regarded as the contact cavity 323; or, the contact part 322 is disposed on the second part 3212, in which case the first part 3211, the third part 3213 and the fourth part 3214 are all omitted, and the space to the left of the second part 3212 can be regarded as the contact cavity 323; or, the contact part 322 is disposed on the fourth part 3214, in which case the first part 3211, the second part 3212 and the third part 3213 are all omitted, and the space to the right of the fourth part 3214 can be regarded as the contact cavity 323.

[0092] At least a portion of the contact cavity 323 overlaps with the stylus 9 in a direction perpendicular to the direction in which the stylus 9 enters the contact cavity 323.

[0093] The fifth type of chip

[0094] Figure 8 This is a perspective view of the fifth type of chip in this utility model; Figure 9 This is a schematic diagram showing the contact between the processing box with the fifth type of chip and the stylus when viewed along the longitudinal direction.

[0095] In this embodiment, the support surface 321a for supporting the contact portion 322 is configured in an arc shape, and correspondingly, the contact portion 322 is also arc-shaped, such as... Figure 9 As shown, when the processing box 100 is installed, there are multiple ways in which the contact part 322 can contact the stylus 9. Specifically, the contact part 322 can contact the tip 93 / first intersection line 931 of the stylus 9, or it can contact the first contact surface 911 / second contact surface 921.

[0096] It can be seen that the arc-shaped contact portion 322 can reduce the positional accuracy requirements of the contact portion 322 / chip 32 in the processing box. Conversely, even if the contact portion 322 / chip 32 has a certain error from the predetermined installation position, the contact portion 322 can still form a stable electrical contact with the contact pin 9.

[0097] The sixth type of chip

[0098] Figure 10 This is a perspective view of the sixth type of chip in this utility model; Figure 11 This is a schematic diagram showing the contact between the processing box with the sixth type of chip and the stylus when viewed along the longitudinal direction.

[0099] Similar to the fifth type of chip, the contact portion 322 in this embodiment is still set in an arc shape, but the support surface 321a used to support the contact portion 322 is no longer set in an arc shape. At this time, the contact portion 322 can move relative to the base 321, and the contact portion 322 can also contact the stylus 9 in the above-mentioned ways. That is, the contact portion 322 can contact the first intersection line 931 or the first contact surface 911 / second contact surface 921.

[0100] The contact portion 322 is movable relative to the base 321. On the one hand, it can increase the contact area between the contact portion 322 and the stylus 9, and on the other hand, it can reduce the deformation of the stylus 9. This not only prevents the elastic fatigue of the stylus 9, but also reduces the wear of the stylus 9 and improves the service life of the stylus 9.

[0101] (Positioning of the processing box)

[0102] Figure 12 This is a perspective view of the processing box, after the first and second units are separated.

[0103] Unlike some of the embodiments described above, in the following processing box 100', the third guided part 100E1 and / or the first guided part 100F1 are eliminated. In this case, only one guided part will be provided at each of the two longitudinal ends of the processing box 100'. When installing the processing box 100', the user will no longer need to align the two guided parts with the two guide rails of the second guide rail H103 on the driving side F of the processing box 100', and will no longer need to align the two guided parts with the two guide rails of the first guide rail H1012 on the non-driving side E of the processing box 100'. In this way, the installation and disassembly process of the processing box 100' will be simplified, and the user experience will be improved.

[0104] like Figure 12 As shown, the processing box 100' also includes a first connector 100b and a second connector 100c for connecting the first unit 10 and the second unit 20. The first connector 100b is configured as a tension spring, and the second connector 100c is configured as a pin. This connection method helps to reduce the difficulty of assembling and disassembling the processing box 100'. Through the second connector 100c, the first unit 10 and the second unit 20 can rotate relative to each other, that is, the first unit 10 and the second unit 20 can rotate relative to each other around the second connector 100c.

[0105] like Figure 13B As shown, in the non-driving side E, along the mounting direction X of the processing cartridge 100', the first connector 100b is located between the third guided part 100E1 and the second connector 100c. That is, the first connector 100b is closer to the photosensitive element 13 and the developing element 22 than the second connector 100c. In this way, the photosensitive element 13 and the developing element 22 are less likely to separate from each other, and the imaging quality of the processing cartridge 100' can remain stable.

[0106] Furthermore, along the mounting direction X of the processing box 100', the first connector 100b is closer to the chip assembly 30 than the second connector 100c, so that the contact between the chip assembly 30 / chip 32 / contact portion 322 and the contact pin 9 will be more stable.

[0107] The limiting mechanism in the processing box 100' after the third guided part 100E1 and / or the first guided part 100F1 is described below with reference to the accompanying drawings. The limiting mechanism has at least one of the functions of guiding the processing box during installation and positioning the processing box after it is installed to a predetermined position.

[0108] First type of limiting mechanism

[0109] Figure 13A This is a perspective view of the processing box of this utility model having the first type of limiting mechanism; Figure 13BThis is a schematic diagram of a processing box with the first type of limiting mechanism viewed along the longitudinal direction; Figure 14 This is a schematic diagram of a processing box with the first type of limiting structure viewed from a direction perpendicular to the longitudinal direction.

[0110] In this embodiment, at least one of the driving-side end piece and the non-driving-side end piece of the processing box 100' is provided with a fifth guided part 21E1. The fifth guided part 21E1 is part of the driving-side end piece / non-driving-side end piece, or a contact piece installed on the driving-side end piece / non-driving-side end piece. During the installation and removal of the processing box 100', the fifth guided part 21E1 contacts the third guide rail H115 / fourth guide rail H111. At the same time, the first guided part 100F1 contacts the second guide rail H103, and the fourth guided part 100E2 contacts the first guide rail H1012. In this way, the processing box 100' can be stably supported and accurately guided to the predetermined installation position. After the processing box 100' reaches the predetermined installation position, the fifth guided part 21E1 still supports the processing box 100'.

[0111] Preferably, at least a portion of the fifth guided portion 21E1 faces the rear in the installation direction X. In the longitudinal direction Y, the fifth guided portion 21E1 does not protrude from the non-drive side end piece 21E of the second unit and is not easily broken. The fifth guided portion 21E1 is located inside the first guided portion 100F1 / fourth guided portion 100E2, or in other words, the fifth guided portion 21E1 is closer to the handle 12 than the first guided portion 100F1 / fourth guided portion 100E2, or in other words, the fifth guided portion 21E1 is located between the first guided portion 100F1 and the fourth guided portion 100E2, so that the processing box 100' can be supported more stably.

[0112] On the other hand, by supporting the fifth guided part 21E1 with the third guide rail H115 / fourth guide rail H111, the processing box 100' is supported in the imaging device. Not only is it unnecessary to provide a protrusion protruding from the end member at the longitudinal end of the processing box 100', but the user only needs to align the fourth guided part 100E2 with the corresponding rail to install the processing box 100'. Conversely, if the fifth guided part 21E1 cannot be supported by the third guide rail H115 / fourth guide rail H111, then a protrusion that can be supported by the third guide rail H115 / fourth guide rail H111 must be provided on the end member, and such a protrusion is prone to breakage.

[0113] Furthermore, such as Figure 12 As shown, the second unit housing 21 includes a bottom shell 21a and a top cover 21b joined together, with the unused toner contained between the bottom shell 21a and the top cover 21b. Figure 14As shown, the bottom shell 21a is hidden. A straight line D1 and D2 are drawn along the longitudinal direction Y, passing through the two ends of the photosensitive element 13 and perpendicular to the Y direction. An imaging region Q is formed between the straight line D1 and the straight line D2. A part of the fifth guided part 21E1 is located in the imaging region Q. In this way, the photosensitive element 13 can be supported more stably.

[0114] When the processing box 100' reaches the predetermined installation position, the stylus 9 will apply a pushing force to the processing box 100' opposite to the installation direction X. During the imaging operation of the processing box 100', the rotating components (photosensitive element 13, developing element 22, etc.) in the processing box will also generate a pushing force on the processing box 100' as a whole opposite to the installation direction during rotation. In this embodiment, along the installation direction X, the fifth guided part 21E1 is located at the rear end of the driving side end part / non-driving side end part, and the fifth guided part 21E1 forms a surface contact with the third guide rail H115 / fourth guide rail H111. This structural design can effectively counteract the pushing force and prevent the processing box 100' from flipping in the direction opposite to the installation direction X, so that the processing box 100' is stably positioned in the imaging device. Correspondingly, the stylus 9 and the chip 32 / contact part 322 can also maintain stable electrical contact.

[0115] The second type of limiting mechanism

[0116] Figure 15 This is a perspective view of the second type of limiting mechanism involved in this utility model relative to the processing box shell.

[0117] In this embodiment, the limiting mechanism is an abutment 25 (which can be regarded as the fifth guided part) provided in the second unit housing 21. Along the installation direction X, the abutment 25 is provided at the rear end of the second unit housing 21. Specifically, the abutment 25 is provided at the rear end of the bottom shell 21a. Along the longitudinal direction Y, the abutment 25 can be one or more.

[0118] like Figure 15 As shown, the second unit housing 21 has a mounting groove 24 at its rear end, and the abutment 25 is movably disposed in the mounting groove 24. Preferably, an elastic member 26 is also disposed between the abutment 25 and the second unit housing 21. The elastic member 26 is part of the limiting mechanism in this embodiment and is used to push the abutment 25 away from the second unit housing 21. At the same time, under the action of the elastic member 26, the position of the processing box 100' in the imaging device can also be effectively adjusted. For example, during the installation of the processing box 100', even if the processing box 100' does not reach the optimal installation position, it can be adjusted to the optimal installation position under the action of the elastic member 26.

[0119] After the processing box 100' is installed in the predetermined position of the imaging device, the abutment 25 abuts against the inclined surface H112 in the receiving space H116. Under the action of the elastic member 26, the abutment 25 and the inclined surface H112 remain in the abutment state, so that the aforementioned pushing force on the processing box 100' can be offset by the abutment 25. Finally, the flipping of the processing box 100' in the direction opposite to the installation direction X is suppressed, and the processing box 100' is stably positioned in the imaging device. Correspondingly, the stylus 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0120] Understandably, when the abutment 25 is fixedly disposed in the mounting slot 24, the abutment 25 can still prevent the processing box 100' from flipping in the opposite direction to the mounting direction X, and maintain stable electrical contact between the contact pin 9 and the chip 32 / contact portion 322.

[0121] The third type of limiting mechanism

[0122] Figure 16 This is a perspective view of the third limiting mechanism involved in this utility model, relative to the processing box housing.

[0123] Similar to the second type of limiting mechanism, the limiting mechanism in this embodiment is also an abutment 25 (which can be regarded as the fifth guided part) provided in the second unit housing 21. Along the installation direction X, the abutment 25 is located at the rear end of the second unit housing 21. After the processing box 100' is installed in the predetermined position of the imaging device, the abutment 25 abuts against the inclined surface H112 in the accommodating space H116.

[0124] In this embodiment, the abutment 25 is made of an elastic material (such as a metal sheet, sponge, rubber, silicone, etc.). In this way, not only can the elastic element 26 be omitted, but the position of the processing box 100' can also be adjusted. In particular, when the abutment 25 is made of rubber / silicone, a greater frictional force can be generated between the abutment 25 and the inclined surface H112, thereby ensuring that the processing box 100' is more stably positioned in the imaging device.

[0125] Similar to the second limiting mechanism, the abutment 25 in this embodiment can also be fixed.

[0126] The fourth type of limiting mechanism

[0127] Figure 17 This is a perspective view of the processing box with a fourth type of limiting mechanism involved in this utility model.

[0128] Similar to the first type of limiting mechanism, the limiting mechanism in this embodiment is also a fifth guided part 27 provided on at least one of the driving-side end piece and the non-driving-side end piece. The fifth guided part 27 is in contact with the third guide rail H115 / fourth guide rail H111. However, in this embodiment, the fifth guided part 27 is configured to be deformable / movable relative to the second unit housing 21. Since the third guide rail H115 / fourth guide rail H111 are both located inside the imaging device, the surface of the third guide rail H115 / fourth guide rail H111 can also be regarded as the inner wall of the imaging device.

[0129] For example, the fifth guided part 27 is mounted to the drive-side end piece / non-drive-side end piece via an elastic member, or the fifth guided part 27 is configured as a protrusion with a hollow structure. Therefore, the position of the processing box 100' can also be adjusted. When the processing box 100' reaches the predetermined installation position, the pushing force on the processing box 100' can be offset by the fifth guided part 27. Finally, the flipping of the processing box 100' in the direction opposite to the installation direction X is suppressed, and the processing box 100' is stably positioned in the imaging device. Correspondingly, the stylus 9 and the chip 32 / contact part 322 can also maintain stable electrical contact.

[0130] Fifth type of limiting mechanism

[0131] Figure 18 This is a perspective view of the fifth type of limiting mechanism involved in this utility model, relative to the processing box shell.

[0132] Similar to the fourth type of limiting mechanism, the limiting mechanism in this embodiment is also configured as a fifth guided part 27 that is deformable / movable relative to the second unit housing 21. The fifth guided part 27 contacts the third guide rail H115 / fourth guide rail H111. However, in this embodiment, the fifth guided part 27 is configured as a torsion spring that is detachably mounted on the second unit housing 21 or the drive-side end piece / non-drive-side end piece.

[0133] The function of the torsion spring is similar to that in the above embodiment, and will not be repeated here. It should be noted that the torsion spring 27 is installed in a detachable manner, so that the user can decide whether to install the torsion spring 27 according to the installation requirements of the processing box 100', thereby improving the applicability flexibility of the processing box 100'.

[0134] The sixth type of limiting mechanism

[0135] Figure 19 This is a perspective view of the sixth limiting mechanism involved in this utility model relative to the processing box shell, taken apart.

[0136] Similar to the first type of limiting mechanism and the second type of limiting mechanism, the limiting mechanism in this embodiment is also configured to be at least one abutment 25 (which can be regarded as the fifth guided part) installed on the second unit housing 20. In this embodiment, the abutment 25 is provided on the face cover 21b. When the processing box 100' is installed in the predetermined position, the face cover 21b is opposite to the horizontal plane H113. At the same time, the abutment 25 abuts against the horizontal plane H113. Thus, the aforementioned pushing force on the processing box 100' can be offset by the abutment 25. Finally, the flipping of the processing box 100' in the direction opposite to the installation direction X is suppressed. The processing box 100' is stably positioned in the imaging device. Correspondingly, the stylus 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0137] Furthermore, the abutment 25 can also be configured to be flexible, so that the processing box 100' can be adjusted to the optimal installation position.

[0138] In particular, when the abutment 25 is made of rubber / silicone, greater friction can be generated between the abutment 25 and the inclined surface H112, thereby ensuring that the processing box 100' is more stably positioned in the imaging device.

[0139] Along the longitudinal direction Y of the processing box 100', at least a portion of the second-to-sixth limiting mechanisms are located within the imaging region Q.

[0140] Various embodiments of the chip assembly 30 and the limiting mechanism have been described above. However, it should be understood that any one of the various embodiments of the chip assembly 30 and any one or more of the various embodiments of the limiting mechanism can be combined with each other to make it easier for the user to install and remove the processing box. At the same time, the processing box can be more stably positioned in the imaging device, and correspondingly, the chip 32 / contact 322 forms a stable electrical contact with the stylus 9.
