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 toward 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.

[0043] [Processing cartridge]

[0044] Figure 2A and Figure 2B It is a three-dimensional diagram of the processing box involved in the utility model.

The developing member 22 is arranged opposite to the photosensitive member 13 and is used to transport unused toner stored in the second unit housing 21 toward the photosensitive member 13, so as to develop the electrostatic latent image formed on the surface of the photosensitive member 13.

[0046] Furthermore, the processing box 100 also includes a handle 12 connected to the first unit shell 11 / the second unit shell 21, through which the user can conveniently take the processing box 100.

[0047] The longitudinal end of the photosensitive member 13 is also provided with a first driving assembly for receiving and / or transmitting driving force. The first driving assembly can be one component or two components. Figure 2AAs shown, the first driving component includes a first driving force receiving member 15 for receiving driving force and a driving force transmitting member 14 for transmitting driving force. The first driving force receiving member 15 is combined with the driving force output member H114 to receive driving force, and the driving force transmitting member 14 is used to transmit the driving force to the developing member 22.

[0048] A second driving assembly 23 for receiving and / or transmitting driving force is also disposed at the longitudinal end of the developing member 22. The second driving assembly 23 may be one component or two components.

[0049] In some embodiments, the first driving force receiving member 15 and the second driving component 23 receive driving force from the imaging device respectively, and then respectively drive the photosensitive member 13 and the developing member 22 to rotate. In this embodiment, the imaging device can be provided with two driving force output members so that the first driving force receiving member 15 and the second driving component 23 are driven respectively, or the imaging device can be provided with one driving force output member so that the first driving force receiving member 15 and the second driving component 23 are simultaneously combined with the driving force output member and driven.

[0050] In some embodiments, one of the first driving force receiving member 15 and the second driving component 23 receives the driving force from the imaging device, and the driving force transmitting member 14 transmits the driving force to the second driving component 23, or the second driving component 23 transmits the driving force to the driving force transmitting member 14. In this embodiment, the first driving component and the second driving component 23 can be arranged on the same side of the processing box 100, or can be arranged on both longitudinal sides of the processing box 100 respectively.

[0051] like Figure 2A As shown, the processing box 100 is also provided with a recessed portion 100a for receiving a driving force output member, and along the longitudinal direction Y, the recessed portion 100a is adjacent to the photosensitive member 13, and 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 recessed portion 100a, and the third driving component 231 is used to drive at least one of the powder feeding member, the stirring member and the like located in the second unit 20 to rotate, wherein the stirring member is used to stir the toner, and the powder feeding member is in contact with the developing member 22 and is used to transport the toner toward the developing member 22.

[0052] Along the longitudinal direction Y, the side where the recessed portion 100a is provided is the driving side F, and the side opposite to the driving side F is the non-driving side E. Hereinafter, the example in which both the first driving component and the second driving component 23 are provided on the driving side F is used for explanation.

[0053] 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, and 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 formed integrally or separately with the first unit housing 11, and similarly, the second unit driving side end piece 21F and the second unit non-driving side end piece 21E are formed integrally or separately with the second unit housing 21, and when a split 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 respectively combined with the corresponding housing in the form of end covers.

[0054] Regardless of the form adopted, the first driving side end piece 11F and the second driving side end piece 21F are respectively located at one longitudinal end of the first unit shell 11 and the second unit shell 21, and the first non-driving side end piece 11E and the second non-driving side end piece 21E are respectively located at the other longitudinal end of the first unit shell 11 and the second unit shell 21. Therefore, the first driving side end piece 11F and the second driving side end piece 21F can be collectively referred to as the driving side end piece of the processing box 100, and the first non-driving side end piece 11E and the second non-driving side end piece 21E can be collectively referred to as the non-driving side end piece of the processing box 100, and the first unit 10 and the second unit 20 are connected to each other through the driving side end piece and the non-driving side end piece.

[0055] Furthermore, the processing box 100 also includes a first guided portion 100F1 and a second guided portion 100F2 arranged on the driving side end piece, and a third guided portion 100E1 and a fourth guided portion 100E2 arranged on the non-driving side end piece. Specifically, each of the guided portions 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 arranged on the driving side end piece 11F of the first unit, the second guided portion 100F2 is a protrusion arranged on the driving side end piece 21F of the second unit, the third guided portion 100E1 and the fourth guided portion 100E2 are both protrusions arranged on the non-driving side end piece 11E of the first unit, and the first unit 10 is positioned in the imaging device through the third guided portion 100E1 and the fourth guided portion 100E2.

[0056] In some embodiments, the driving force output member 14 is configured to be movable between a vertical state and an inclined state. Before the processing box 100 is installed at a predetermined position of the imaging device, the driving force output member 14 is in an inclined state. At this time, the rotation axis of the driving force output member 14 is inclined relative to the rotation axis L1 of the photosensitive member 13. As the processing box 100 is installed, the driving force output member 14 gradually moves toward the vertical state. When the processing box 100 is installed at a predetermined position of the imaging device, the driving force output member 14 reaches a vertical state. At this time, the rotation axis of the driving force output member 14 is coaxial with or parallel to the rotation axis L1 of the photosensitive member 13; for this reason, the processing box 100 is also provided with a straightening member 16 for forcing the driving force output member 14 to move from the inclined state to the vertical state.

[0057] In some embodiments, the processing box 100 further includes a chip assembly 30 for establishing a communication connection with the 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 the first unit housing 11 or the second unit housing 21, preferably, the support portion 31 is formed integrally 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 a contact portion 322 (such as a contact portion 32222222233) in the chip 32 for electrically contacting the imaging device Figure 3 The first unit housing 11 or the second unit housing 21 is detachable from the support portion 31.

[0058] Preferably, the contact portion 322 is arranged in a planar shape, and the contact portion 322 is not arranged on the same side as the first drive component / second drive component 23 to reduce the influence of the vibration generated by the first drive component / second drive component 23 on the contact portion 322 during the imaging of the processing box 100. In the figure, the contact portion 322 is arranged on the non-driving side E.

[0059] (Chip Components)

[0060] As described above, the chip 32 is used to electrically contact with the contact pins in the imaging device to establish a communication connection with the imaging device. The structure of the chip 32 is described below.

[0061] The first chip

[0062] Figure 3 It is a three-dimensional diagram of the first chip in the utility model; Figure 4 It is a partial schematic diagram of the electrical contact between the first chip and the contact pin in the utility model; Figure 5 It is a schematic diagram when observing the process box with the first chip in the longitudinal direction and contacting with the contact pin.

[0063] The chip 32 includes a substrate 321 and a contact portion 322 arranged on the substrate. According to the number of contact pins, the contact portion 322 is set to be at least one; the contact pin 9 is set to be a triangular metal sheet, including a first conductor 91 and a second conductor 92 intersecting at a tip portion 93. The first conductor 91 and the second conductor 92 can be formed separately or integrally, and the space between the two can be filled with a filler or a vacant portion 94 can be formed.

[0064] 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 portion 93 can all contact the contact portion 322 to achieve electrical contact between the chip 32 and the contact pin, and 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 contact pin 9, and the first intersection line 931 is a part of the tip portion 93. Preferably, the first intersection line 931 is the end line of the tip portion 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 portion 93. Such a contact pin 9 and the contact portion 322 can also be regarded as forming a line contact, and the projection of the contact line between the two on the arc surface is the first intersection line 931. At this time, 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.

[0065] When the substrate 321 abuts against the first intersection line 931, the direction of the substrate 321 facing the tip portion 93 is the front, or the direction opposite to the direction in which the tip portion 93 enters the following contact cavity 323 is the front, the direction opposite to the front is the rear, and the direction intersecting the front-to-back direction is the up-down direction, wherein the first conductor 91 is located above the second conductor 92, and the direction intersecting the front-to-back direction and the up-down direction is the left-right direction, and the left-right direction is parallel to the longitudinal direction Y, wherein 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-to-back direction, the up-down direction, and the left-to-right direction are orthogonal, and in this coordinate system, during the installation of the processing box 100, the chip 32 approaches the contact pin 9 from the rear of the contact pin 9.

[0066] Overall, the contact pin 9 further has a third contact surface 95 facing leftward and a fourth contact surface 96 facing rightward, that is, the third contact surface 95 and the fourth contact surface 96 are arranged opposite to 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 .

[0067] 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, wherein the first portion 3211, the second portion 3212, the third portion 3213 and the fourth portion 3214 enclose a contact cavity 323, at least a portion of the contact portion 322 is located in the contact cavity 323, and the contact cavity 323 has an opening 323a facing forward / contact pin 9, and the contact pin 9 can enter the contact cavity 323 through the opening 323a.

[0068] 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 the present embodiment, the support surface 321a is configured to be perpendicular to the up-down direction and face upward, and thus, at least a portion of the contact portion 322 is also perpendicular to the up-down direction and faces upward; more specifically, the contact portion 322 also has a second intersection line 3221 intersecting with the first portion 3211.

[0069] like Figure 4 and Figure 5 As shown, when the processing box 100 is installed, the opening 323a faces the contact pin 9, at least a part of the terminal end 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 forms a line contact with the contact pin 9. Compared with the contact manner of the first intersection line 931 and the contact portion 322, the second contact surface 921 has a larger area that can contact the contact portion 322, and the chip 32 / contact portion 322 and the contact pin 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, thereby further enhancing the electrical contact stability between the chip 32 / contact portion 322 and the contact pin 9.

[0070] In some embodiments, the contact portion 322 may further extend to the first portion 3211 , so that the electrical contact between the contact pin 9 and the contact portion 322 is more stable and the contact amount may also be increased.

[0071] The second chip

[0072] Fig. 6A It is a schematic diagram when observing the process box with the second chip in the longitudinal direction and contacting with the contact pin.

[0073] 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 321 a is configured to be inclined relative to the front-rear direction.

[0074] like Fig. 6A As shown, the second contact surface 921 is in contact with the contact portion 322. At this time, the contact pin 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 stable electrical contact between the chip 32 / contact portion 322 and the contact pin 9, and the surface contact formed by the contact pin 9 and the chip 32 / contact portion 322 makes the pressing force applied by the contact pin 9 to the chip 32 / contact portion 322 more balanced, and the processing box can be more stably maintained in the imaging device. Accordingly, the electrical contact stability between the chip 32 / contact portion 322 and the contact pin 9 is further enhanced.

[0075] Continue as Fig. 6A As shown, the third guided portion 100E1 has a center M, and the fourth guided portion 100E2 has a center N. The line connecting the center M and the center N forms a line segment MN. The straight line perpendicular to the support surface 321a / contact portion 322 and passing through the support surface 321a / contact portion 322 is C1. 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.

[0076] The third chip

[0077] Figure 6B It is a schematic diagram of the process box with the third chip in contact with the contact pin when viewed along the longitudinal direction.

[0078] Similar to the second chip, the contact portion 322 in this embodiment is still arranged in the contact cavity 323, and the coupling portion 322 / support surface 321a is still arranged to be inclined relative to the front-to-back direction, but the contact portion 322 is in contact with 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.

[0079] In this embodiment, the straight line C2 is perpendicular to the support surface 321a / contact portion 322 and passes through the support surface 321a / contact portion 322. The straight line C2 also does not pass through the line segment MN, that is, the straight line C2 does not intersect the line segment MN.

[0080] Similar to the first chip, the contact portion 322 may also be configured to form a line contact with the first contact surface 911 .

[0081] According to the structure of the second chip and the third chip, in some embodiments, the contact portion 322 can also be arranged on the surface of the contact cavity 323 facing the second part 3212 or the fourth part 3214, and the contact portion 322 is in contact with the third contact surface 95 or the fourth contact surface 96. At this time, the surface is the support surface of the contact portion 322, and 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.

[0082] The first contact surface 911 , the second contact surface 921 , the third contact surface 95 and the fourth contact surface 96 may be collectively referred to as side surfaces of the contact pin 9 , and the chip 32 / contact portion 322 may be configured to contact the side surfaces.

[0083] The fourth chip

[0084] Figure 7 It is a three-dimensional diagram of the fourth chip in the utility model.

[0085] Similar to the first chip, the chip 32 in the embodiment still includes a substrate 321 and a contact portion 322 arranged on the substrate 321, the substrate 321 is formed with a contact cavity 323, and the contact portion 322 is located in the contact cavity 323. Specifically, at least one contact portion 322 is arranged on the support surface 321a / contact portion 322, and the support surface 321a / contact portion 322 is perpendicular to the up and down direction, and the support surface 321a / contact portion 322 faces upward.

[0086] The substrate 321 in this embodiment is not provided with the third portion 3213 , ie, the upper opening of the contact cavity 323 , so that the contact pin 9 can smoothly enter the contact cavity 323 , and the position accuracy requirement of the chip 32 / substrate 321 can be reduced.

[0087] Furthermore, the second part 3212 or the fourth part 3214 of the substrate 321 can also be omitted, so that the left or right side of the contact cavity 323 is open. This design can make the contact pin 9 enter the contact cavity 323 more smoothly and further reduce the position accuracy requirements of the chip 32 / substrate 321.

[0088] Based on the inventive concept of the above-mentioned embodiment, 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 portion 322 is arranged 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 portion 322 is arranged 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 portion 322 is arranged 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.

[0089] At least a portion of the contact cavity 323 overlaps with the contact needle 9 in a direction perpendicular to the direction in which the contact needle 9 enters the contact cavity 323 .

[0090] The fifth chip

[0091] Figure 8 It is a three-dimensional diagram of the fifth chip in the utility model; Fig. 9 1 is a schematic diagram of a process box having a fifth chip in contact with a contact pin as viewed in the longitudinal direction.

[0092] In this embodiment, the support surface 321a for supporting the contact portion 322 is configured to be arc-shaped, and accordingly, the contact portion 322 is also arc-shaped, such as Fig. 9 As shown, when the processing box 100 is installed, the contact portion 322 can contact the contact pin 9 in various ways. Specifically, the contact portion 322 can contact the tip portion 93 / first intersection line 931 of the contact pin 9, or can contact the first contact surface 911 / second contact surface 921.

[0093] It can be seen that the arc-shaped contact portion 322 can reduce the position accuracy requirement of the contact portion 322 / chip 32 in the processing box. Conversely, even if the contact portion 322 / chip 32 has a certain error with the predetermined installation position, the contact portion 322 can still form a stable electrical contact with the contact pin 9.

[0094] The sixth chip

[0095] Fig.10 It is a three-dimensional diagram of the sixth chip in the utility model; Fig.11 3 is a schematic diagram of a process box having a sixth chip in contact with a contact pin as viewed in the longitudinal direction.

[0096] Similar to the fifth chip, the contact portion 322 in this embodiment is still configured to be arc-shaped, but the support surface 321a for supporting the contact portion 322 is no longer configured to be arc-shaped. At this time, the contact portion 322 can move relative to the base 321, and the contact portion 322 can contact the contact pin 9 in the above-mentioned multiple ways, that is, the contact portion 322 can contact the first intersection line 931, and can also contact the first contact surface 911 / the second contact surface 921.

[0097] The contact portion 322 is movable relative to the base 321, which can increase the contact area between the contact portion 322 and the contact pin 9 on the one hand, and reduce the deformation of the contact pin 9 on the other hand, which can not only prevent the elastic fatigue of the contact pin 9, but also reduce the wear of the contact pin 9 and increase the service life of the contact pin 9.

[0098] (Positioning of the process cartridge)

[0099] Fig.12It is a three-dimensional diagram of a first unit and a second unit of a processing box involved in the utility model after being separated from each other.

[0100] Different from some of the above-mentioned embodiments, in the following processing box 100', the third guided portion 100E1 and / or the first guided portion 100F1 are cancelled. At this time, only one guided portion will be provided at each of the two longitudinal ends of the processing box 100'. When the user installs the processing box 100', it is no longer necessary to align the two guided portions on the driving side F of the processing box 100' with the two guide rails of the second guide rail H103 at the same time, and it is no longer necessary to align the two guided portions on the non-driving side E of the processing box 100' with the two guide rails of the first guide rail H1012 at the same time. In this way, the installation and removal process of the processing box 100' will become simpler, and the user's experience can be improved.

[0101] like Fig.12 As shown, the processing box 100' also includes a first connecting member 100b and a second connecting member 100c for connecting the first unit 10 and the second unit 20, wherein the first connecting member 100b is configured as a tension spring and the second connecting member 100c is configured as a latch. This connection method is beneficial to reducing the difficulty of assembling and disassembling the processing box 100'. Through the second connecting member 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 connecting member 100c.

[0102] like Fig. 13B As shown, in the non-driving side E, along the installation direction X of the processing box 100', the first connecting member 100b is located between the third guided portion 100E1 and the second connecting member 100c, that is, the first connecting member 100b is closer to the photosensitive member 13 and the developing member 22 than the second connecting member 100c. In this way, the photosensitive member 13 and the developing member 22 are less likely to separate from each other, and the imaging quality of the processing box 100' can be kept stable.

[0103] Furthermore, along the installation direction X of the process box 100 ′, the first connecting member 100 b is closer to the chip assembly 30 than the second connecting member 100 c , so that the contact between the chip assembly 30 / chip 32 / contact portion 322 and the contact pin 9 becomes more stable.

[0104] The limiting mechanism in the processing box 100' after the third guided portion 100E1 and / or the first guided portion 100F1 are removed is described below in conjunction with 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 installation to a predetermined position.

[0105] The first limit mechanism

[0106] Fig.13A It is a three-dimensional diagram of a processing box with a first limiting mechanism of the utility model; Fig. 13B is a schematic diagram of a process box having a first limiting mechanism observed along the longitudinal direction; Fig.14 It is a schematic diagram of a processing box having a first limiting structure observed along a direction perpendicular to the longitudinal direction.

[0107] In this embodiment, a fifth guided portion 21E1 is provided on at least one of the driving side end piece and the non-driving side end piece of the processing box 100'. The fifth guided portion 21E1 is a part of the driving side end piece / non-driving side end piece, or is 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 portion 21E1 contacts the third guide rail H115 / the fourth guide rail H111, and at the same time, the first guided portion 100F1 contacts the second guide rail H103, and the fourth guided portion 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, and when the processing box 100' reaches the predetermined installation position, the fifth guide portion 21E1 still supports the processing box 100'.

[0108] Preferably, at least a portion of the fifth guided portion 21E1 faces the rear of the installation direction X, and along the longitudinal direction Y, the fifth guided portion 21E1 does not protrude from the second unit non-driving side terminal piece 21E and is not easily broken, and the fifth guided portion 21E1 is located on the inner side of 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.

[0109] On the other hand, the fifth guided portion 21E1 is supported by the third guide rail H115 / fourth guide rail H111 to achieve support of the processing box 100' in the imaging device. Not only does it not need to provide a protrusion protruding from the end piece at the longitudinal end of the processing box 100', but the user only needs to align the fourth guided portion 100E2 with the corresponding rail to achieve installation of the processing box 100'. Conversely, if the fifth guided portion 21E1 is not 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 piece, and there is a problem that the protrusion is easily broken.

[0110] Further, such as Fig.12As shown, the second unit housing 21 includes a bottom shell 21a and a cover 21b that are combined with each other, and the unused toner is accommodated between the bottom shell 21a and the cover 21b. Fig.14 As shown, the bottom shell 21a is hidden, and a straight line D1 and a straight line D2 are respectively made along the longitudinal direction Y, passing through the two ends of the photosensitive member 13 and perpendicular to the Y direction. An imaging area Q is formed between the straight line D1 and the straight line D2, and a part of the fifth guided portion 21E1 is located in the imaging area Q. In this way, the photosensitive member 13 can be supported more stably.

[0111] When the processing box 100' reaches the predetermined installation position, the contact pin 9 will apply a forced thrust to the processing box 100' in the opposite direction of the installation direction X. During the imaging operation of the processing box 100', each rotating member (photosensitive member 13, developing member 22, etc.) in the processing box will also generate a forced thrust to the processing box 100' as a whole in the opposite direction of the installation direction during the rotation process. In this embodiment, along the installation direction X, the fifth guided portion 21E1 is located at the rear end of the driving side end member / non-driving side end member, and the fifth guided portion 21E1 is in surface contact with the third guide rail H115 / fourth guide rail H111. This structural design can effectively offset the forced thrust and prevent the processing box 100' from turning over in the direction opposite to the installation direction X, so that the processing box 100' is stably positioned in the imaging device. Accordingly, the contact pin 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0112] The second limiting mechanism

[0113] Fig.15 It is a three-dimensional diagram of the second limiting mechanism involved in the utility model, which is decomposed relative to the processing box shell.

[0114] The limiting mechanism in this embodiment is an abutment member 25 (which can be regarded as the fifth guided portion) arranged in the second unit shell 21. Along the installation direction X, the abutment member 25 is arranged at the rear end of the second unit shell 21. Specifically, the abutment member 25 is arranged at the rear end of the bottom shell 21a. Along the longitudinal direction Y, the abutment member 25 can be set to one or more.

[0115] like Fig.15As shown, the second unit shell 21 has a mounting groove 24 arranged at the rear end, and the abutment member 25 is movably arranged in the mounting groove 24. Preferably, an elastic member 26 is also arranged between the abutment member 25 and the second unit shell 21. The elastic member 26 is a part of the limiting mechanism in this embodiment, and is used to push the abutment member 25 in a direction away from the second unit shell 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 process of the processing box 100', even if the processing box 100' does not reach the optimal installation position, under the action of the elastic member 26, the processing box 100' can be adjusted to the optimal installation position.

[0116] After the processing box 100' is installed to the predetermined position of the imaging device, the abutment 25 abuts against the inclined surface H112 in the accommodating space H116. Under the action of the elastic member 26, the abutment 25 and the inclined surface H112 are maintained in an abutment state, so that the above-mentioned forced thrust exerted on the processing box 100' can be offset by the abutment 25. Finally, the processing box 100' is suppressed from flipping in the direction opposite to the installation direction X, and the processing box 100' is stably positioned in the imaging device. Accordingly, the contact pin 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0117] It is understandable that when the abutment member 25 is fixedly disposed in the mounting groove 24 , the abutment member 25 can still prevent the process box 100 ′ from turning in the direction opposite to the mounting direction X and maintain stable electrical contact between the contact pin 9 and the chip 32 / contact portion 322 .

[0118] The third limiting mechanism

[0119] Fig.16 It is a three-dimensional diagram of the third limiting mechanism involved in the utility model, which is decomposed relative to the processing box shell.

[0120] Similar to the second limiting mechanism, the limiting mechanism in this embodiment is also an abutment 25 (which can be regarded as the fifth guided portion) arranged in the second unit shell 21, and along the installation direction X, the abutment 25 is located at the rear end of the second unit shell 21. After the processing box 100' is installed to the predetermined position of the imaging device, the abutment 25 abuts against the inclined surface H112 in the accommodating space H116.

[0121] The abutment 25 in this embodiment is made of an elastic material (such as metal sheet, sponge, rubber, silicone, etc.). In this way, not only the elastic member 26 can 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 friction 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.

[0122] Similar to the second middle limiting mechanism, the abutment member 25 in this embodiment can also be arranged in a fixed manner.

[0123] The fourth limit mechanism

[0124] Fig.17 It is a three-dimensional diagram of a processing box with a fourth limiting mechanism involved in the utility model.

[0125] Similar to the first limiting mechanism, the limiting mechanism in this embodiment is also a fifth guided portion 27 arranged on at least one of the driving side end piece and the non-driving side end piece, and the fifth guided portion 27 is in contact with the third guide rail H115 / the fourth guide rail H111, but the fifth guided portion 27 in this embodiment is arranged to be deformable / movable relative to the second unit shell 21; since the third guide rail H115 / the fourth guide rail H111 are both located in the imaging device, the surface of the third guide rail H115 / the fourth guide rail H111 can also be regarded as the inner wall of the imaging device.

[0126] For example, the fifth guided portion 27 is mounted to the driving side end piece / non-driving side end piece through an elastic member, or the fifth guided portion 27 is set as a protrusion with a hollow structure, so that the position of the processing box 100' can also be adjusted. When the processing box 100' reaches the predetermined installation position, the forced thrust exerted on the processing box 100' can be offset by the fifth guided portion 27. Finally, the processing box 100' is suppressed from flipping in the direction opposite to the installation direction X, and the processing box 100' is stably positioned in the imaging device. Accordingly, the contact pin 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0127] The fifth limit mechanism

[0128] Fig.18 It is a three-dimensional diagram of the fifth limiting mechanism involved in the utility model, which is decomposed relative to the processing box shell.

[0129] Similar to the fourth limiting mechanism, the limiting mechanism in this embodiment is also configured as a fifth guided portion 27 that is deformable / movable relative to the second unit housing 21, and the fifth guided portion 27 is in contact with the third guide rail H115 / fourth guide rail H111, but the fifth guided portion 27 in this embodiment is configured as a torsion spring that is detachably mounted on the second unit housing 21 or the driving side end piece / non-driving side end piece.

[0130] The function of the torsion spring is similar to that of the above embodiment and will not be described again. 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'.

[0131] The sixth limit mechanism

[0132] Fig.19 It is a three-dimensional diagram of the sixth limiting mechanism involved in the utility model, which is decomposed relative to the processing box shell.

[0133] Similar to the first limiting mechanism and the second limiting mechanism, the limiting mechanism in this embodiment is also configured to have at least one abutment 25 (which can be regarded as the fifth guided portion) installed on the second unit housing 20. The abutment 25 in this embodiment is arranged on the surface cover 21b. When the processing box 100' is installed to the predetermined position, the surface cover 21b is opposite to the horizontal plane H113. At the same time, the abutment 25 abuts against the horizontal plane H113, so that the above-mentioned forced thrust exerted 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. Accordingly, the contact pin 9 and the chip 32 / contact portion 322 can also maintain stable electrical contact.

[0134] Furthermore, the abutting member 25 may also be configured to have elasticity, so that the process cartridge 100 ′ may be adjusted to an optimal installation position.

[0135] In particular, when the abutting member 25 is made of rubber / silicone, a greater friction force can be generated between the abutting member 25 and the inclined surface H112, thereby ensuring that the process cartridge 100' is more stably positioned in the image forming device.

[0136] At least a portion of the second to sixth limiting mechanisms are located within the imaging area Q along the longitudinal direction Y of the process box 100 ′.

[0137] Various embodiments of the chip assembly 30 and the limiting mechanism are described above respectively. 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. Accordingly, the chip 32 / contact portion 322 forms a stable electrical contact with the contact pin 9.
