[0094] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.

[0095] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0096] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc., mentioned in this application are used only to distinguish different devices, units, or elements, and are not intended to limit the order of functions performed by these devices, units, or elements, or their interdependencies.

[0097] It should be noted that the terms "a" and "a plurality of" used in this application are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0098] An image forming apparatus can be a printer, copier, or similar device. In this apparatus, the cartridge and the main body are separate. Communication between the main body and the cartridge requires electrical contacts through an identification unit. Once the main body makes electrical contact with the identification unit, the unit detects that the cartridge is properly installed or that it is an original cartridge. Only after this detection is complete can normal image output be performed.

[0099] Taking an image forming apparatus using a toner cartridge as an example, a chip can be installed on the toner cartridge. When the user manually pushes the toner cartridge into the image forming apparatus, the chip installed on the toner cartridge makes contact with the electrical contacts of the main component of the image forming apparatus through sliding friction. The inventors discovered that during the sliding friction between the chip installed on the toner cartridge and the electrical contacts of the main component of the image forming apparatus, the chip installed on the toner cartridge is easily worn. For example, when the user uses a large pushing force to push the toner cartridge into the image forming apparatus, the chip installed on the toner cartridge is easily worn, resulting in scratches on the chip, thereby reducing the chip's lifespan and further affecting print quality.

[0100] To address the aforementioned issues, this application provides a cartridge including a transmission mechanism. This transmission mechanism can drive the recognition unit to contact the electrical contacts of the main component, thereby reducing the risk of wear and scratches on the recognition unit and improving its service life while ensuring normal communication between the cartridge and the image forming apparatus. The cartridge can be a toner cartridge with a drum unit, etc.

[0101] Figure 1 An exploded view of a transmission mechanism according to an embodiment of this application is shown. Figure 2 A schematic diagram of a transmission mechanism according to an embodiment of this application is shown. Figure 1 and Figure 2As shown, the transmission mechanism disclosed in this application includes a support module 101, a first thrust mechanism 102, and a drive module 103. It should be understood that various possible descriptions of the structure and function of the transmission mechanism described below can be applied to the functional implementation of the box.

[0102] Figure 3A This diagram illustrates the structural state of the transmission mechanism installed inside the box according to an embodiment of this application, with the identification unit in its initial position. Figure 3B This diagram illustrates the structural state of the transmission mechanism installed inside the box according to an embodiment of this application, with the identification unit located at the target position. (See diagram below.) Figure 3A and Figure 3B As shown, the first thrust mechanism 102 is used to push the support module 101. The drive module 103 is connected to the first thrust mechanism 102. At this time, the drive module 103 drives the first thrust mechanism 102 so that the first thrust mechanism 102 pushes the support module 101 within a preset time period, causing the identification unit A to move from the initial position to the target position, thereby realizing the contact between the identification unit A and the electrical contact B of the main component.

[0103] In some embodiments, such as Figure 1 and Figure 2 As shown, when the identification unit A includes a storage medium, the storage medium includes a storage element and an electrical contact surface. The storage unit can be a read-only memory, an access memory, etc. Specific types can be found in related technologies and will not be detailed here.

[0104] The aforementioned electrical contact surface can be electrically connected to the storage unit. This storage element stores information about the cartridge, such as its specifications, toner type, and manufacturer. The contact surface is used to electrically connect to the electrical contact B of the main component of the image forming apparatus, allowing the image forming apparatus to read the relevant information stored in the storage unit through the electrical contact B of the main component and the contact surface of the storage unit to determine whether the cartridge meets the requirements of the image forming apparatus. Therefore, the aforementioned storage medium can serve as an electrical detection unit mounted on the cartridge, assisting the image forming apparatus in performing cartridge information detection.

[0105] In some embodiments, such as Figure 1 and Figure 2 As shown, the identification unit A can be a conductive unit, which is used to electrically connect with the electrical contact B of the main component of the image forming apparatus. For example, the conductive unit can be a high-voltage contact of the imaging component, and the image forming apparatus can supply power to the box normally by contacting the high-voltage contact with the electrical contact B of the main component.

[0106] In some embodiments, such as Figure 1 and Figure 2As shown, the aforementioned identification unit A is an adapter electrically connected to the chip in the cartridge. For example, the chip in the cartridge can refer to the storage medium described above, or it can refer to a microchip with computing capabilities. When the image processing device makes electrical contact with the adapter through the electrical contact B of the main component, and further indirectly connects to the chip in the cartridge through the electrical contact B, the chip in the cartridge is not limited by the position of the electrical contact B of the main component, allowing for more flexible positioning. Furthermore, even if the adapter suffers some wear due to long-term use, only the adapter needs to be replaced, effectively reducing costs.

[0107] like Figure 1 and Figure 2 As shown, the identification unit A described above may have multiple communication terminals, each forming a conductive contact. These conductive contacts include a VCC contact, an SDA contact, a GND contact, and an SCL contact. The VCC contact is used to conduct electricity with an external power supply unit to obtain the voltage required for the cell chip to operate. The SDA contact is a data communication contact, the GND contact is a grounding contact, and the SCL contact is a clock signal contact. These four conductive contacts respectively contact the electrical contacts B of the corresponding main components on the image forming apparatus, thereby achieving an electrical connection between the image forming apparatus and the cell chip.

[0108] In practical applications, such as Figure 3A and Figure 3B As shown, when the first thrust mechanism 102 pushes the support module 101 to move, the recognition unit A supported by the support module 101 can contact the electrical contact B of the main component of the image forming apparatus in a surface-to-surface contact manner. At this time, the contact between the recognition unit A supported by the support module 101 and the electrical contact B of the main component of the image forming apparatus does not require sliding friction, but is achieved through surface-to-surface contact. Therefore, the technical solution of this embodiment can reduce the probability of wear and scratches on the recognition unit A, thereby improving the service life of the recognition unit A. Furthermore, when the first thrust mechanism 102 pushes the support module 101 to move the recognition unit A from the initial position to the target position within a preset time period, the first thrust mechanism 102 can apply a force to the support module 101, making the recognition unit A and the electrical contact B of the main component make tight contact.

[0109] like Figure 3A As shown, the initial position mentioned above can refer to the position of identification unit A when identification unit A is not in contact with the electrical contact B of the main component, and the position of identification unit A supported by bracket module 101. Figure 3BAs shown, the target position can refer to the position of identification unit A when it comes into contact with the electrical contact B of the main component. The first thrust mechanism 102 can be driven by the drive module 103 manually or mechanically, so that the first thrust mechanism 102 pushes the support module 101 to move the identification unit A from the initial position to the target position within a preset time period.

[0110] In some embodiments, such as Figure 3A and Figure 3B As shown, after the user places the box inside the image forming apparatus, the position of the recognition unit A within the image forming apparatus can be defined as a first initial position. When the box is detected to have been placed inside the image forming apparatus, the drive module 103 can be controlled to drive the first thrust structure to push the support module 101 within a preset time period, causing the support module 101 to move the recognition unit A from the initial position to the target position. When the recognition unit A reaches the target position, it is located at the position where the recognition unit A can contact the electrical contact B of the main component.

[0111] In other embodiments, such as Figure 3A and Figure 3B As shown, after the image forming apparatus forms an image (e.g., a printer performs a printing operation), if the support module 101 drives the recognition unit A to retract from the target position to a certain position, causing the recognition unit A to separate from the electrical contact B of the main component, but before returning to the first initial position, the position where the recognition unit A is located is defined as the second initial position. At this time, the second initial position is located between the first initial position and the target position.

[0112] When the image forming apparatus performs the next image forming, such as Figure 3A and Figure 3B As shown, the first thrust mechanism 102 can be driven by the drive module 103 to push the bracket module 101 to move the identification unit A from the initial position to the target position within a preset time period, so that the identification unit A can re-contact the electrical contact B of the main component.

[0113] In some possible implementations, such as Figure 3A and Figure 3B As shown, the first thrust mechanism 102 can be a pusher, which, through the drive module 103, drives the pusher to push the bracket module 101 within a preset time period, thereby moving the identification unit A from the initial position to the target position along a straight line.

[0114] In practical applications, such as Figure 1 , Figure 2 , Figures 3A to 3BAs shown, the pushing member can be a linear motion mechanism. For example, the pushing member is a reciprocating linear motion mechanism such as a piston or a linear guide. The support module 101 is disposed at the moving end of the reciprocating linear motion mechanism, such as the end of the piston or the slider of the linear guide. The drive module can be a pneumatic drive mechanism, an electric drive mechanism, or a hydraulic drive mechanism. Therefore, the drive module 103 can drive the reciprocating linear motion mechanism to perform linear reciprocating motion, so that the reciprocating linear motion mechanism can push the support module 101 to reciprocate between the initial position and the target position.

[0115] like Figure 1 , Figure 2 , Figures 3A to 3B As shown, when the reciprocating linear motion mechanism pushes the support module 101, it drives the identification unit A along... Figure 2 The identification unit A moves linearly from its initial position to the target position from right to left, causing it to contact the electrical contact B of the main component. When the identification unit A needs to separate from the electrical contact B of the main component, the drive module 103 controls the piston to perform a linear reciprocating motion, so that the reciprocating linear motion mechanism can drive the support module 101 to move the identification unit A along... Figure 2 The identification unit A moves in a straight line from the target position to the initial position from left to right, thereby separating the identification unit A from the electrical contact B of the main component.

[0116] It is understandable that, such as Figure 1 , Figure 2 , Figures 3A to 3B As shown, regardless of whether the identification unit A is along Figure 2 Does the movement proceed in a straight line from the initial position to the target position, from right to left, or does recognition unit A move along...? Figure 2 Move in a straight line from the target position to the initial position from left to right. The initial position can be either the first initial position mentioned above or the second initial position mentioned above.

[0117] In some possible implementations, such as Figures 3A to 3B As shown, when the box includes an imaging component, the aforementioned drive module 103 can be used to rotate along the imaging component to drive the first thrust mechanism 102 to push the support module 101 to move the recognition unit A from the initial position to the target position within a preset time period.

[0118] The aforementioned rotational motion can be either a forward rotation or a reverse rotation of the imaging component. Here, we can set the forward rotation direction to be the same as the imaging component's rotation direction, and the reverse rotation direction to be different from the reverse rotation direction of the imaging component.

[0119] In practical applications, such as Figures 3A to 3BAs shown, the drive module 103 in this embodiment can convert rotational motion into linear motion, so that the drive module 103 can use linear motion to drive the support module 101 to move linearly. In this process, whether it is the forward rotational motion or the reverse rotational motion of the imaging component, within a preset time period, the first thrust mechanism 102 can be used to push the support module 101 to move the recognition unit A along the axial direction of the imaging component from the initial position to the target position, so that the recognition unit A contacts the electrical contact B of the main component.

[0120] like Figures 3A to 3B As shown, when the recognition unit A moves from its initial position to its target position along the axis of the imaging component, the recognition unit A can gradually contact the electrical contact B of the main component along a direction perpendicular to the surface of the electrical contact B, until the recognition unit A makes contact with the electrical contact B of the main component. This contact method not only achieves surface-to-surface contact, but also avoids sliding friction between the recognition unit A and the electrical contact B of the main component, effectively mitigating the problem of scratches and wear on the recognition unit A, thereby extending the lifespan of the recognition unit A.

[0121] like Figure 3A and Figure 3B As shown, taking the end face M of the imaging component away from the support module 101 as a reference, when the identification unit A is in the initial position, the distance between the support module 101 and the end face M of the imaging component is L1; when the identification unit A is in the target position, the distance between the support module 101 and the end face M of the imaging component is L2, satisfying the relationship: L2 > L1.

[0122] like Figure 3A and Figure 3B As shown, it can be used as Figure 3A and Figure 3B The right end face is the end face M of the imaging component. The direction along the axis of the imaging component can be perpendicular to the end face M of the imaging component. The distance between the end face M of the imaging component and the surface of the recognition unit A at the initial position is set to be equal to L1. The distance between the end face M of the imaging component and the surface of the recognition unit A at the target position is set to be equal to L2.

[0123] like Figure 3A and Figure 3B As shown, when the first thrust mechanism 102 pushes the bracket module 101 to move the recognition unit A from the initial position to the target position within a preset time period, it is essentially the process of the first thrust mechanism 102 pushing the bracket module 101 to move the recognition unit A away from the end face M of the imaging component. Therefore, L1 < L2.

[0124] It should be noted that, as Figure 1 , Figure 2 , Figure 3A and Figure 3BAs shown, the side of the first bracket 1011 in this embodiment of the application also has a reset structure 1016. The first bracket 1011 is used to drive the identification unit A to move toward the first thrust mechanism 102 when the reset structure 1016 is subjected to force. For example, the reset structure 1016 may include a reset surface located on the side of the first bracket 1011, and the reset surface is an inclined surface.

[0125] like Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, when the identification unit A needs to be separated from the electrical contact B of the main component, a pushing force can be applied to the inclined surface by the second pushing mechanism. This pushing force has a component on the inclined surface in the axial direction of the imaging component and points in the direction of the first pushing mechanism 102, thereby pushing the first bracket 1011 to move the identification unit A along the contact surface perpendicular to the electrical contact B of the main component. At this time, not only can the separation of the identification unit A from the electrical contact B of the main component be achieved, but the friction between the identification unit A and the electrical contact B of the main component can also be reduced to the minimum, thereby further alleviating the possibility of wear and scratches on the identification unit A and improving the service life of the identification unit A.

[0126] In some embodiments, such as Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, the inclined surface can be set to a non-smooth surface, that is, a rough surface. This can increase the friction between the first thrust mechanism 102 and the inclined surface, thereby increasing the contact time between the first thrust mechanism 102 and the inclined surface, and thus more reliably realizing the separation of the identification unit A and the electrical contact B of the main component.

[0127] like Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, the first thrust mechanism 102 can be a movable structure located within the image forming apparatus. This movable structure can be manually or controlled by the image forming apparatus to separate the recognition unit A from the electrical contact B of the main component. Here, the movable structure can refer to the implementation of the pusher described above to push the reset surface of the reset structure 1016, thereby allowing the support module 101 to move the recognition unit A from the target position to the initial position, achieving the purpose of retracting the recognition unit A.

[0128] In some possible implementations, such as Figure 1 and Figure 2As shown, the bracket module 101 of this application embodiment includes a first bracket 1011. The first bracket 1011 is provided with a support surface, which is used to support the identification unit A, and the first thrust mechanism 102 can be located on the side of the first bracket 1011 away from the support surface.

[0129] In practical applications, Figure 4A A three-dimensional structural schematic diagram of the first thrust mechanism according to an embodiment of this application is shown. Figure 4A As shown, the drive module 103 includes a drive gear 1031, and the first thrust mechanism 102 includes a transmission gear 1021 and a pusher 1022. The transmission gear 1021 meshes with the drive gear 1031, so that the drive gear 1031 can drive the transmission gear 1021 to rotate. The pusher 1022 is located on one side of the transmission gear 1021 and faces the end face of the first bracket 1011. Therefore, the pusher 1022 can rotate with the rotation of the transmission gear 1021, and during the rotation, it can push the first bracket 1011, so that the first bracket 1011 can drive the identification unit A to move from the initial position to the target position.

[0130] In one alternative approach, Figure 5A A three-dimensional structural schematic diagram of the support module 101 according to an embodiment of this application is shown. Figure 5A As shown, the first support 1011 has a force-receiving member 1012 on its end face facing the pusher 1022. When the transmission gear 1021 is engaged with the drive gear 1031 and driven, the force-receiving member 1012 is pushed by the pusher 1022, causing the first support 1011 to move in a direction away from the transmission gear 1021, thus moving the identification unit A from its initial position to its target position. Here, the pusher 1022 and the force-receiving member 1012 can constitute a motion conversion mechanism, allowing the rotational motion of the transmission gear 1021 to be converted into linear motion of the force-receiving member 1012 along the axial direction of the imaging component.

[0131] For example, such as Figure 4A and Figure 5A As shown, the pusher 1022 has at least one actuating tooth P on its end face facing the force-receiving member 1012, and the force-receiving member 1012 has at least one driven protrusion Q on its end face facing the pusher 1022. The actuating tooth P is used to contact the side of the corresponding driven protrusion Q during the process of the transmission gear 1021 being driven by the drive gear 1031, so as to push the force-receiving member 1012, causing the first bracket 1011 to move in a direction away from the transmission gear 1021, and causing the identification unit A to move from the initial position to the target position.

[0132] like Figure 4A and Figure 5AAs shown, since the pusher 1022 is located on one side of the transmission gear 1021 and faces the end face of the first bracket 1011, when the transmission gear 1021 is driven by the drive gear 1031, the transmission gear 1021 will also drive the pusher 1022 to rotate while rotating. Since the pusher 1022 has at least one actuating tooth P on the end face facing the force-receiving member 1012, the pusher 1022 can also drive the actuating tooth P to contact the side of the driven protrusion Q during rotation, thereby causing the side of the actuating tooth P to apply a force to the side of the corresponding driven protrusion Q. This causes the driven protrusion Q to transmit the force to the first bracket 1011 through the force-receiving member 1012, thereby causing the first bracket 1011 to move in a direction away from the transmission gear 1021 and drive the identification unit A to move from the initial position to the target position.

[0133] like Figure 4A and Figure 5A As shown, the side surface of the driven protrusion Q includes a first inclined surface Q1 and a first arcuate surface Q2. The first inclined surface Q1 and the first arcuate surface Q2 are continuously connected, meaning that the first inclined surface Q1 and the first arcuate surface Q2 are tangent. The side surface of the actuating tooth P includes a second inclined surface P1 and a second arcuate surface P2, which are continuously connected, meaning that the second inclined surface P1 and the second arcuate surface P2 are tangent. When the side surface of the actuating tooth applies a force to the side surface of the driven protrusion Q, the first inclined surface Q1 contacts the second inclined surface P1. At this time, the force has a component pointing towards the force-receiving member 1012 in the axial direction of the imaging component. Therefore, under the actuation of the actuating tooth, the driven protrusion Q can drive the first support 1011 to move in a direction away from the transmission gear 1021 via the force-receiving member 1012, and drive the recognition unit A to move from the initial position to the target position.

[0134] For example, such as Figure 4A As shown, multiple tooth-like structures (such as three) can be provided on the end face of the pusher 1022, and they are provided in a sawtooth shape along the circumferential direction of the pusher 1022. Each tooth-like structure can be a symmetrical structure, and the two symmetrical sides of the tooth-like structure form a 45° angle.

[0135] like Figure 2 , Figure 4A and Figure 5A As shown, when the drive gear 1031 drives the transmission gear 1021 to rotate, since the two symmetrical sides of the tooth structure form a 45° angle, regardless of whether the transmission gear 1021 rotates forward or backward, it can push the first bracket 1011 through the end face between the pusher 1022 and the force-receiving member 1012, so that the first bracket 1011 drives the identification unit A to move from the initial position to the target position, thereby achieving contact between the identification unit A and the electrical contact B of the main component, thus realizing normal communication.

[0136] In some embodiments, Figure 4B This illustration shows a cross-sectional view of a first thrust mechanism 102 mounted on a frame, according to an embodiment of this application. Figure 4C This illustration shows another cross-sectional view of the first thrust mechanism 102 mounted on a frame according to an embodiment of this application. Figure 5B A cross-sectional schematic diagram of the support module 101 according to an embodiment of this application is shown. Figures 4A to 4C , Figure 5A and Figure 5B As shown, in this embodiment, both the force-receiving component 1012 and the pushing component 1022 are sleeve structures. The force-receiving component 1012 is provided with a first connecting member 1013, which is used to connect the frame 104 of the box. The first connecting member 1013 is movable relative to the frame 104. The pushing component 1022 is provided with a second connecting member 1023, which is used to connect the frame 104 of the box and is rotatable relative to the frame 104.

[0137] like Figure 2 , Figure 4B , Figure 4C and Figure 5B As shown, when the force-bearing member 1012 is pushed by the pusher 1022, causing the first bracket 1011 to move away from the transmission gear 1021, the first connecting member 1013, driven by the force-bearing member 1012, moves away from the frame 104 and is not affected by the frame 104. Simultaneously, since the second connecting member 1023 is located on the pusher 1022, and the pusher 1022 is located on one side of the transmission gear 1021 and faces the first bracket 1011, the second connecting member 1023 will also rotate during the rotational motion of the transmission gear 1021 driven by the drive gear 1031. Because the second connecting member 1023 can rotate relative to the frame 104, its rotational motion will not affect the frame 104, thus achieving motion decoupling between the second connecting member 1023 and the frame 104. As can be seen, when the first connector 1013 of this application embodiment can move relative to the frame 104 and the second connector 1023 can rotate relative to the frame 104, the first connector 1013 can be movably connected to the frame 104 of the box in the axial direction of the imaging component, thereby ensuring that the identification unit A can move between the initial position and the target position.

[0138] For example, when the recognition unit A moves from its initial position along the axis of the imaging component between the initial position and the target position, the movement trajectory of the first support can be constrained to minimize the possibility of deviation from the movement trajectory of the recognition unit A. For instance, the movement trajectory of the first support can be constrained by adding an end cap. The principle of the end cap's trajectory constraint is described below with reference to the accompanying drawings.

[0139] Figure 6A This diagram shows the end cap and frame in a disassembled state according to an embodiment of this application. Figure 6B A schematic diagram of the end cap, frame, and drive mechanism in an assembled state, according to an embodiment of this application, is shown. Figure 6A and Figure 6B As shown, the box in this embodiment of the application also includes an end cap 106, which is located on the side of the first thrust mechanism 102 near the first support 1011.

[0140] like Figure 2 , Figure 5A and Figure 5B As shown, the first bracket 1011 may also be provided with a limiting part 1014. For example... Figure 6A and Figure 6B As shown, the end cap 106 has a window G through which the first support 1011 and the limiting portion 1014 pass. The limiting portion 1014 is used to cooperate with the window G of the end cap 106 to limit the rotation of the first support 1011 relative to the end cap 106.

[0141] like Figure 2 , Figure 3A , Figure 5A , Figure 5B , Figure 6A and Figure 6B As shown, when the identification unit A is in the initial position, the identification unit A provided on the support surface of the first bracket 1011 and the first bracket 1011 can be located within the window G of the end cover 106, or located on the side of the end cover 106 near the first thrust mechanism 102. At this time, the end cover 106 can be equivalent to a protective cover for the bracket module 101, the first thrust mechanism 102 and the drive module 103.

[0142] like Figure 3B and Figure 6B As shown, when the identification unit A is located at the target position, the first bracket 1011 can extend from the end face of the end cover 106 away from the first thrust mechanism 102 through the window G of the end cover 106, so that the identification unit A can contact the electrical contact B of the main component.

[0143] like Figure 2 , Figure 3A , Figure 5A , Figure 5B , Figure 6Aand Figure 6B As shown, when the first thrust mechanism 102 pushes the support module 101 to move the identification unit A from the initial position to the target position, the first support 1011 and the limiting part 1014 provided on the first support 1011 can pass through the window G in the axial direction of the imaging component away from the first thrust mechanism 102. The window G can constrain the movement direction of the first support 1011 by cooperating with the limiting part 1014, ensuring that the first support 1011 moves along the axial direction of the imaging component without rotating relative to the end cover 106.

[0144] In some embodiments, such as Figure 2 , Figure 3A , Figure 5A , Figure 5B , Figure 6A and Figure 6B As shown, when the limiting part 1014 is a columnar structure and is located on the upper end face of the first support 1011, the window G may include a first window G1 and a second window G2. The second window G2 is located above the first window G1 and communicates with the first window G1. The first window G1 allows the first support 1011 to pass through, and the second window G2 allows the limiting part 1014 to pass through. Furthermore, the size and outline shape of the second window G2 can match the size and outline shape of the columnar limiting part 1014 to ensure that when the limiting part 1014 passes through the second window G2, the second window G2 can strictly constrain the movement trajectory of the limiting part 1014, so that the limiting part 1014 moves as far along the axial direction of the imaging member as possible. Since the limiting part 1014 is located on the first support 1011, even if the size of the first window G1 through which the first support 1011 passes is relatively large, it can be ensured that the first support 1011 moves along the axial direction of the imaging member without the problem of the movement trajectory deviating from the axial direction of the imaging member.

[0145] As can be seen, when the first support 1011 moves the recognition unit A from the initial position to the target position along the axial direction of the imaging component under the push of the first thrust mechanism 102, the movement trajectory of the first support 1011 is constrained in the axial direction of the imaging component by the cooperation of the limiting part 1014 and the window G. This allows the recognition unit A to make direct contact with the electrical contact B of the main component, without the problem of sliding friction contact, or the movement path of the recognition unit A being deviated, resulting in poor contact between the recognition unit A and the electrical contact B of the main component, which would affect the printing quality. When the first support 1011 moves the recognition unit A from the target starting position to the initial position along the axial direction of the imaging component, the movement trajectory of the first support 1011 is constrained to the axial direction of the imaging component by the cooperation of the limiting part 1014 and the window G. This allows the recognition unit A to move away from the electrical contact B of the main component along the direction perpendicular to the contact surface of the electrical contact B of the main component. Thus, during the separation process between the recognition unit A and the electrical contact B of the main component, there will be no sliding friction, thereby reducing the possibility of scratches and wear on the recognition unit A and improving its service life. For example, as... Figure 5A and Figure 5B As shown, the first bracket 1011 is also provided with a guide portion 1015, which is used to guide the first bracket 1011 to be installed onto the frame 104. The guide portion 1015 can be installed on the end face of the first bracket 1011 facing the first thrust mechanism 102.

[0146] like Figure 5B As shown, considering that the force-bearing component 1012 is a sleeve structure, the first connecting component 1013 and the guide portion 1015 can both be located inside the force-bearing component 1012, thereby improving the integration of the support module 101, facilitating the miniaturization of the support module 101, and reducing unnecessary space occupation. Since the end face of the force-bearing component 1012 facing the pusher 1022 is provided with at least one driven protrusion Q, and the force-bearing component 1012 is a sleeve structure, when the first connecting component 1013 and the guide portion 1015 are both located inside the force-bearing component 1012, the first snap-fit ​​portion K1, the first connecting component 1013, and the guide portion 1015 are all surrounded by the driven protrusion Q.

[0147] In one example, such as Figure 4A and Figure 4CAs shown, the second connector 1023 can be a first L-shaped hook, which is used to connect to the first slot R1 of the frame 104. The first L-shaped hook can move relative to the first slot R1. For example, when the frame 104 has a connecting shaft, the first slot R1 can be an annular groove formed on the outer wall of the connecting shaft, and the hook of the first L-shaped hook can hook into the annular groove. Since the pusher 1022 of the second connector 1023 is located on one side of the transmission gear 1021 and faces the end face of the first bracket 1011, the hook of the first L-shaped hook on the second connector 1023 can rotate along the annular groove during the rotation of the second connector 1023. This ensures that the second connector 1023 will not affect the frame 104 of the box during rotation and that the second connector 1023 rotates more stably on the frame 104.

[0148] In some embodiments, such as Figure 2 As shown, the drive gear 1031 in this embodiment can be mounted on the drive shaft 105, and the drive gear 1031 is provided with a third connector 1032. The third connector 1032 can be a second L-shaped hook. The second L-shaped hook is used to connect to the second slot R2 of the drive shaft 105, and the second L-shaped hook can move relative to the second slot R2. Here, the second slot R2 can be an annular groove provided on the drive shaft 105, and the hook of the second L-shaped hook can be engaged in the second annular groove.

[0149] For example, when the drive gear 1031 is fixed on the drive shaft 105, the drive shaft can drive the drive gear 1031 to rotate during rotation. As the drive gear 1031 rotates with the drive shaft, the second annular groove can guide the hook of the second L-shaped hook provided on the drive gear 1031, preventing the drive gear 1031 from shaking during rotation.

[0150] like Figure 2 As shown, the drive shaft 105 can be a drive shaft inside the box. The drive shaft 105 can be an added shaft based on related technologies, or it can be an existing rotating shaft (such as a toner cartridge shaft) in the box that is compatible with the function of the drive shaft 105. That is, the drive shaft 105 is compatible with the function of an existing rotating shaft (such as a toner cartridge shaft) in the box.

[0151] For example, such as Figure 2 As shown, when the drive gear 1031 is rotatably mounted on the drive shaft 105, the second annular groove guides the second L-shaped hook on the drive gear 1031 during rotation, thus preventing the drive gear 1031 from affecting the drive shaft 105 during rotation. Therefore, when the transmission mechanism is used inside a box, it is only necessary to install the drive gear 1031 on the existing drive shaft 105, thereby simplifying the modification complexity of the box.

[0152] like Figure 6A and Figure 6B As shown, when the existing shaft in the box (e.g., the toner cartridge shaft) is compatible with the function of the drive shaft 105, a mounting hole H can be provided on the end cover 106 of the box, and the drive shaft 105 is installed in the mounting hole H to ensure the installation stability of the drive shaft 105.

[0153] For example, such as Figure 2 As shown, the aforementioned drive gear 1031 can be an electric drive gear 1031, or a battery can be installed on the drive gear 1031 or other parts to power the drive gear 1031. Within a preset time period, the battery can power the drive gear 1031, causing the drive gear 1031 to drive the transmission gear 1021 to rotate within the preset time period. This allows the pusher 1022 on the transmission gear 1021 to push the force-receiving member 1012, causing the force-receiving member 1012 to move from its initial position to its target position within the preset time period.

[0154] For example, such as Figure 2 , Figure 6A and Figure 6B As shown, an electronic switch can be configured for the battery, which can be controlled by the image forming apparatus. If it is necessary to push the recognition unit A into contact with the electrical contact B of the main component, a reset signal can be sent to the electronic switch through the image forming apparatus, causing the electronic switch to conduct in response to the reset signal. In this way, the battery can supply power to the drive gear 1031, causing the drive gear 1031 to drive the transmission gear 1021 to rotate. This causes the pushing member 1022 of the transmission gear 1021 to cooperate with the force-receiving member 1012 provided on the first bracket 1011, pushing the first bracket 1011 to move the recognition unit A from the initial position to the target position, so that the recognition unit A contacts the electrical contact B of the main component. Figure 1 and Figure 2 As shown, to further improve the reliability of the contact between the identification unit A and the electrical contact B of the main component when the identification unit A is in the target position, the support module 101 is locked when the identification unit A is in the target position. This prevents the identification unit A from accidentally separating from the electrical contact B of the main component due to insufficient thrust of the first thrust mechanism 102.

[0155] like Figure 2 , Figures 4A to 4C , Figure 5A and Figure 5B As shown, the first connector 1013 in this embodiment includes a first snap-fit ​​portion K1, which is used to snap-fit ​​with a second snap-fit ​​portion K2 provided on the frame 104 so that the first bracket 1011 is locked when the identification unit A is located in the target position.

[0156] like Figure 4CAs shown, a third latching part K3 can also be provided on the frame 104 of the box. The first latching part K1 is also used to latch with the third latching part K3 provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is in the initial position. When the identification unit A moves from the initial position to the target position along the axial direction of the imaging component, the third latching part K3 and the second latching part K2 are distributed along the axial direction of the imaging component in a direction away from the frame 104.

[0157] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, considering that the force-bearing member 1012 is pushed by the pusher 1022, causing the first bracket 1011 to move in a direction away from the transmission gear 1021, the first connecting member 1013, driven by the force-bearing member 1012, moves away from the frame 104 along the axial direction of the imaging component. The third locking part K3 and the second locking part K2 can be positioned on the same straight line, the direction of which can be the same as the axial direction of the imaging component. When the first connecting member 1013 moves away from the frame 104 along the axial direction of the imaging component under the drive of the force-bearing member 1012, the first locking part K1 can separate from the third locking part K3 in its initial position. When the identification unit A is located at the target position, the first locking part K1 engages with the second locking part K2 at the target position.

[0158] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the frame 104 is a solid structure, the first connector 1013 and the guide portion 1015 are both located on the outer side of the solid structure, and the second snap-fit ​​portion K2 can be provided on the outer wall of the solid structure. When the frame 104 is a hollow structure, the first connector 1013 and the guide portion 1015 can be located either on the outer side or inside the hollow structure. When the frame 104 is a hollow structure, the first connector 1013 is provided on the inner wall of the frame 104, and the driven protrusion Q is provided on the outer wall of the frame 104. In this case, the first connector 1013 and the driven protrusion Q are separated by the outer wall of the frame 104.

[0159] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5BAs shown, the frame 104 may have a connecting shaft that passes through the drive gear 1031 and enters the sleeve structure of the pusher 1022. The first L-shaped hook and the second locking part K2 may be located on both sides of the transmission gear 1021, and the first L-shaped hook and the third locking part K3 may be located on both sides of the transmission gear 1021.

[0160] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the connecting shaft is a solid structure, the second locking part K2 and the third locking part K3 can be provided on the outer wall of the connecting shaft. In this case, the first locking part K1 and the guide part 1015 are both located between the inner wall of the sleeve structure of the connecting shaft and the pusher 1022. In another example, when the connecting shaft has a cavity with an opening, the opening faces the direction of the first bracket 1011. In this case, both the first locking part K1 and the guide part 1015 can extend into the cavity through the opening. In this case, the second locking part K2 and the third locking part K3 can be provided on the inner wall of the cavity.

[0161] In one example, such as Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the first latching part K1 is a latching hole, the latching hole is used to engage with the buckle provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is in the target position. Here, both the second latching part K2 and the third latching part K3 can be implemented in the form of a buckle. In another example, the first latching part K1 is a buckle, which is used to engage with the latching hole provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is in the target position. Here, both the second latching part K2 and the third latching part K3 can be implemented in the form of a latching hole.

[0162] To facilitate understanding of the movement process of the identification unit from the initial state to the target state in the embodiments of this application, Figure 7A This illustration shows a three-dimensional structural diagram of the transmission mechanism of the identification unit in the initial position according to an embodiment of this application. Figure 7B This diagram shows a cross-sectional view of the transmission mechanism of the identification unit in the initial position according to an embodiment of this application. The following example uses a mechanism located on the inner wall of the frame. Figure 7A and Figure 7B Describe it.

[0163] like Figure 7A and Figure 7BAs shown, when the transmission gear 1021 is driven to rotate by the drive gear 1031, the transmission gear 1021 can drive the pusher 1022 to rotate. The actuating tooth P provided on the pusher 1022 can contact the side of the driven protrusion Q provided on the force-receiving member 1012 and apply a force to the side of the driven protrusion Q. The side of the driven protrusion Q is inclined, which can generate a component force in the axial direction of the imaging member and point in the direction of the first bracket 1011. In this way, the first locking part K1 gradually disengages from the third locking part K3 and moves in the direction close to the second locking part K2. Correspondingly, the force-receiving member 1012 provided with the driven protrusion Q can drive the recognition unit A to move from the initial position in the direction away from the transmission gear 1021, that is, in the direction close to the target position, through the first bracket 1011.

[0164] Figure 8A This diagram illustrates a three-dimensional structural state of the transmission mechanism of the identification unit at the target position according to an embodiment of this application. Figure 8B This diagram illustrates a cross-sectional view of the transmission mechanism of the identification unit at the target location, according to an embodiment of this application. Figure 8A and Figure 8B As shown, when the first latching part K1 moves to the position of the second latching part K2, the first latching part K1 gradually latches together with the second latching part K2, and the identification unit A moves from the initial position to the target position, so that the identification unit A contacts the electrical contact B of the main component.

[0165] It should be noted that, Figure 7A and Figure 7B , Figure 8A and Figure 8B A connecting shaft is provided on the frame 104, and the connecting shaft passes through the transmission gear 1021. The end of the connecting shaft facing the first bracket 1011 has an open cavity. The connecting shaft has a third engaging portion K3 and a second engaging portion K2 along the axis away from the transmission gear 1021. Both the second engaging portion K2 and the third engaging portion K3 are engaging holes, and the first engaging portion K1 is a snap-fit. The first connecting member 1013 extends into the cavity through the opening, and the first engaging portion K1 of the first connecting member 1013 engages with the third engaging portion K3. The engaging hole is a through hole that penetrates the side wall of the connecting shaft. Both the first connecting member 1013 and the guide portion 1015 can extend into the cavity through the opening.

[0166] like Figure 1 , Figure 2 , Figure 7A and Figure 7B , Figure 8A and Figure 8BAs shown, to improve the autonomous retraction capability of the first support 1011, the transmission mechanism may further include an elastic element S. One end of the elastic element S can be connected to the interior of the force-receiving member 1012, and the other end can be connected to the interior of the pushing member 1022. Furthermore, the elastic element S can be sleeved on the connecting shaft. When the first support 1011 is subjected to a force pointing in the direction of the transmission gear 1021, on the one hand, the first locking part K1 of the first connecting member 1013 can separate from the second locking part K2, and under the rebound action of the elastic element S, the first support 1011 with the force-receiving member 1012 is quickly pulled, causing the identification unit A to return from the target position to the initial position.

[0167] In some alternative methods, Figure 9A This paper shows a schematic diagram of a connection structure between a drive gear and a drive shaft according to an embodiment of this application. Figure 9B An exploded view of a connection between a drive gear and a drive shaft according to an embodiment of this application is shown. Figure 9A and Figure 9B As shown, the drive gear 1031 in this embodiment can be a one-way rotary bearing structure. The drive shaft 105 can be connected to the drive gear 1031 via a one-way bearing 1033. For example, the one-way bearing 1033 can be sleeved on the drive shaft 105, and the drive gear 1031 can be mounted on the one-way bearing.

[0168] like Figure 9A and Figure 9B As shown, when the drive gear 1031 is mounted on the drive shaft 105, if the drive shaft 105 is compatible with other functions, such as the toner cartridge shaft function, then the drive shaft 105 and the drive gear 1031 can be decoupled under certain conditions through this one-way rotary bearing structure.

[0169] like Figure 9A and Figure 9B As shown, taking an image forming apparatus with a drive shaft 105 compatible with a toner cartridge shaft as an example, when the cartridge is installed inside the image forming apparatus, the drive shaft 105 can drive the one-way bearing 1033 to rotate along the first rotation direction, thereby driving the drive gear 1031 to rotate along the first rotation direction with the drive shaft 105. During the rotation of the drive gear 1031, the drive gear 1031 drives the transmission gear 1021 to rotate, using the pusher 1022 provided on the transmission gear 1021 to push the support module 101, causing the support module 101 to move the recognition unit A from the initial position to the target position. When the image forming apparatus recognizes the recognition unit A, the drive shaft 105 rotates along the second rotation direction to perform the printing operation.

[0170] The first and second rotation directions mentioned above are two opposite rotation directions. For example, when the first rotation direction is the forward rotation method of the imaging component, the second rotation direction is the opposite direction of the rotation of the imaging component.

[0171] For example, the forward rotation direction of the imaging component can be either clockwise or counterclockwise. For instance, the first rotation direction may be clockwise, and the second rotation direction may be counterclockwise. Or, for another example, the first rotation direction may be counterclockwise, and the second rotation direction may be clockwise.

[0172] like Figure 9A and Figure 9B As shown, when the image forming apparatus performs a printing operation, the drive shaft 105, being compatible with the drum shaft function, rotates along the second rotation direction. Since the one-way bearing 1033 is mounted on the drive shaft 105 and the drive gear 1031 is fixed to the one-way bearing 1033, the one-way bearing 1033 and the drive gear 1031 fixed to it do not rotate with the drive shaft 105 along the second rotation direction. This ensures the normal operation of the image forming apparatus and reduces the risk of tooth breakage between the drive gear 1031 and the transmission gear 1021, avoiding noise caused by tooth breakage that could affect the user experience. On the other hand, if tooth breakage occurs between the drive gear 1031 and the transmission gear 1021, one or both of them will be damaged, affecting the lifespan of the cartridge.

[0173] In some alternative methods, Figure 10A This diagram illustrates the structural state of the identification unit in the initial position when the transmission gear is missing a tooth, according to an embodiment of this application. Figure 10B This diagram illustrates the structural state of the identification unit at the target position in the case of a missing tooth in the transmission gear, according to an embodiment of this application. Figure 10A and Figure 10B As shown, the transmission gear 1021 in this embodiment of the application includes a toothless portion 1021A and a toothed portion 1021B, and the circumferential length of the toothed portion 1021B is greater than the circumferential length of the toothless portion 1021A.

[0174] like Figure 10A and Figure 10BAs shown, when the identification unit A is in the initial position, the drive gear 1031 meshes with the toothed portion 1021B of the transmission gear 1021. Taking a printer as an example, when the cartridge is placed in the printer's toner drawer, the printer can detect when the front cover is closed and control the drive shaft 105 to reverse the drive gear 1031. The drive gear 1031 drives the transmission gear 1021 to rotate, thereby pushing the support module 101 through the pusher 1022 provided on the transmission gear 1021. This causes the support module 101 to move the identification unit A from the initial position to the target position, allowing the identification unit A to contact the electrical contact B of the main component. At this time, the drive gear 1031 contacts the toothed portion 1021A of the transmission gear 1021.

[0175] like Figure 10A and Figure 10B As shown, when the printer performs a printing operation, although the drive gear 1031 rotates, because the identification unit A can contact the electrical contact B of the main component, the drive gear 1031 contacts the toothed portion 1021A of the transmission gear 1021. Therefore, although the drive gear 1031 is still rotating with the drive shaft 105 (e.g., the drive shaft 105 drives the drive gear 1031 to rotate forward), the transmission gear 1021 no longer rotates, effectively preventing tooth knocking between the drive gear 1031 and the transmission gear 1021. After the printer performs a printing operation, the identification unit A can be returned to its initial state, at which point the drive gear 1031 meshes with the toothed portion 1021B of the transmission gear 1021.

[0176] This application also provides an image forming apparatus that can reduce the risk of wear and scratches on the recognition unit through a housing disposed therein, thereby ensuring the chip's lifespan. The image forming apparatus here can be a printer, copier, etc., but is not limited to these.

[0177] Figure 11 An exploded structural schematic diagram of an image forming apparatus according to an embodiment of this application is shown. Figure 11 As shown, the image forming apparatus disclosed in this application embodiment may include an electrical contact B of a main component and a housing 100, which is detachably mounted to the image forming apparatus. The identification unit A included in the housing is electrically connected to the electrical contact B of the main component at a target location. It should be understood that... Figure 11 Only some structures are shown. Although the unshown structures are described in detail in the embodiments of this application, they can be determined by referring to related technologies.

[0178] In practical applications, the electrical contact B of the main component can refer to the main contact of the image forming apparatus, the cartridge can refer to a photosensitive device such as a toner cartridge, and the identification unit A can refer to a device that can contact the electrical contact B of the main component to achieve data communication. Taking a printer as an example, the cartridge can be pushed into the cartridge mounting section inside the printer, and then the identification unit A inside the cartridge can be electrically connected to the electrical contact B of the main component at the target position, thereby completing the detachable installation of the cartridge.

[0179] like Figure 11 As shown, the image forming apparatus of this application embodiment may further include a second support 201. For example, the second support 201 may be a drawer rail for placing a box. By pulling open the drawer, placing the box inside the drawer, and then pushing the drawer in along the second support 201 as a rail, the box is installed in the image forming apparatus.

[0180] In some alternative methods, such as Figure 11 As shown, the first support 1011 included in the box 100 of this application embodiment has a reset structure 1016 on its side. The image forming apparatus may further include a second thrust mechanism 202 disposed on the second support 201, which matches the reset structure 1016. When the identification unit A contacts the electrical contact B of the main component, the second thrust mechanism 202 acts on the reset structure 1016 of the box and applies a force to separate the identification unit A and the electrical contact B of the main component.

[0181] To better understand the process of installing and removing the cartridge within the image forming apparatus according to the embodiments of this application, Figure 12A A flowchart illustrating the process of installing and removing the cartridge within the printer is shown. Figure 12B This diagram illustrates the positional relationship between the reset structure and the first thrust mechanism 102 during the printing operation. Figure 12C The positional relationship between the reset structure and the first thrust mechanism 102 after printing is shown. The following figures describe the box installation and removal process according to an embodiment of this application. Figures 12A-12C As shown, the method for installing and removing the cartridge within the printer according to an embodiment of this application may include the following steps:

[0182] Step 1201: When the cartridge is installed inside the printer, there is a gap between the identification unit and the electrical contact B of the printer's main component. For example, when the cartridge 100 includes an end cover 106, the identification unit A provided by the bracket module 101 is retracted on the side of the end cover 106 near the first thrust mechanism 102. It can also be understood that the end cover 106 includes an inner side and an outer side, with the inner side being near the first thrust mechanism 102. There is a gap between the identification unit A and the electrical contact B of the printer's main component, that is, the identification unit A is located on the inner side of the end cover 106.

[0183] Step 1202: The printer sends a print command to the motor driver of the drive shaft.

[0184] Step 1203: The motor driver responds to the printing command and controls the motor to drive the drive shaft to rotate. Here, the drive shaft 105 can be a rotating shaft independent of the drum shaft, or it can be a drum shaft (also known as an OPC shaft) that is compatible with the drive shaft function.

[0185] Step 1204: During the rotation of the drive shaft, the drive shaft drives the drive gear to rotate, and the drive gear drives the transmission gear to rotate.

[0186] Step 1205: The transmission gear drives the pusher to push the first bracket, so that the first bracket drives the identification unit to move from the initial position to the target position.

[0187] like Figure 11 , Figures 12A-12C As shown, when the box 100 includes the end cap 106, the process of the identification unit A moving from the initial position to the target position actually involves it extending from the side of the end cap 106 near the first thrust mechanism 102 towards the side of the end cap 106 away from the first thrust mechanism 102. When the identification unit A is in the target position, the pushing end of the second thrust mechanism 202 provided on the second bracket 201 is opposite to the reset structure 1016 provided on the side of the first bracket 1011.

[0188] Step 1206: When the identification unit is in the target position, the identification unit contacts the electrical contacts of the main component, so that the printer recognizes the identification unit and performs the printing operation.

[0189] like Figure 11 , Figures 12A-12C As shown, when identification unit A contacts the electrical contact B of the main component, identification unit A and electrical contact B of the main component can communicate, and the printer will then perform normal printing operations. If the printer's drum shaft is compatible with the drive shaft function, if the drum shaft rotates clockwise during the process of identification unit A moving from the initial position to the target position, then after the printer successfully identifies identification unit A, the drum shaft will rotate counterclockwise to perform the printing operation; conversely, if the drum shaft rotates counterclockwise during the process of identification unit A moving from the initial position to the target position, then after the printer successfully identifies identification unit A, the drum shaft will rotate clockwise to perform the printing operation.

[0190] like Figure 11 , Figures 12A-12C As shown, the solution to the tooth breakage between the drive gear 1031 and the transmission gear 1021 can be found in the previous section on... Figure 9A and Figure 9B The disclosed technical solutions can also be referenced. Figure 10A and Figure 10B Another technical solution disclosed herein.

[0191] like Figure 11 , Figures 12A-12C As shown, after the printing operation is completed, the identification unit A and the electrical contact B of the main component can remain in contact, or they can be separated manually or by other control methods. For example, while maintaining contact between the identification unit A and the electrical contact B of the main component, the system can wait for the next printing operation. When the next printing operation begins, it will return to step 1202 and repeat steps 1202 to 1206.

[0192] For example, such as Figure 11 , Figures 12A-12C As shown, when a reset structure is provided on the first bracket 1011, the identification unit A can be manually or controlled by the printer to separate from the electrical contact B of the main component after the printing operation. Taking the manual separation of the identification unit A from the electrical contact B of the main component as an example, the following steps may also be included:

[0193] Step 1207: Open the door of the printer mounting box and pull the drawer of the mounting box to retract the upper-mounted identification unit into the end cover.

[0194] like Figure 11 , Figures 12A-12C As shown, when the door of the printer mounting box 100 is opened, the drawer containing the box 100 is pulled, so that the drawer drives the box 100 to gradually approach the second thrust mechanism 202 under the guidance of the second bracket 201, until the reset structure 1016 provided on the side of the first bracket 1011 inside the box 100 collides with the second thrust mechanism 202, so that the first bracket 1011 drives the identification unit A to retract into the end cover 106.

[0195] like Figure 11 , Figures 12A-12C As shown, when the first bracket 1011 drives the identification unit A back into the end cover 106, the identification unit A separates from the electrical contact B of the main component. If it is necessary to replace or remove the box 100, step 1207 can be performed.

[0196] Step 1208: After pulling out the drawer, remove the box inside or replace it with a new box. For example... Figure 11 , Figures 12A-12C As shown, if a new cartridge 100 is replaced, the process can return to step 1201. Here, during the printer printing operation, the identification unit A contacts the electrical contact B of the main component.

[0197] like Figure 11 , Figures 12A-12C As shown, after the printing operation is complete, you can follow... Figure 12B Manually pull the drawer in the direction of the arrow shown, so that the drawer moves along the second bracket 201. Figure 12AAs the arrow points forward, the reset surface on the first support 1011 gradually approaches the pushing end of the second thrust mechanism 202 on the second support 201, and eventually collides with it. At this point, because the reset surface on the first support 1011 is inclined, under a large reaction force, it generates a component force pointing in the direction of the transmission gear 1021 along the axis of the imaging component. This causes the first support 1011 to separate the identification unit A from the electrical contact B of the main component and retract to a certain extent, while the box continues to move along the drawer. Figure 12B Move in the direction of the arrow shown until... Figure 12C The state shown.

[0198] For example, such as Figure 11 , Figure 12B and Figure 12C As shown, the second thrust mechanism 202 is a blocking block mounted on the second bracket 201. After the printing operation is completed, the printer's front door can be opened and the toner cartridge drawer pulled, causing the toner cartridge drawer to gradually bring the first bracket 1011 into contact with the blocking block. This allows the blocking block to apply force to the reset surface on the first bracket 1011, thereby separating the identification unit A from the electrical contact B of the main component.

[0199] It should be noted that, as Figure 11 , Figures 12A-12C As shown, the first bracket 1011 causes the identification unit A to separate from the electrical contact B of the main component and retract to a certain extent. In addition to being done manually, the retraction operation can also be integrated into the printer's control logic. The printer can control other possible pushing mechanisms to apply force to the reset surface to separate the identification unit A from the electrical contact B of the main component.

[0200] For example, such as Figure 11 , Figures 12A-12C As shown, the second thrust mechanism 202 can be a trigger controlled by the printer, such as a reciprocating motion mechanism like a piston or cam. When the second thrust mechanism 202 is a trigger, after the printer detects that the printing operation is complete, it can actively send a retraction command to the trigger, causing the trigger to apply force to the reset surface on the first bracket 1011, thereby causing the identification unit A to separate from the electrical contact B of the main component.

[0201] Another implementation method can be as follows: Figure 11 , Figures 12A-12BAs shown, taking a printer as an example, when cartridge 100 is installed in the printer and the printer is powered on, the reset mechanism of the identification unit A inside the printer (i.e., the mechanism that implements the function of the second thrust mechanism) is activated, pushing the identification unit A to reset. At this time, the consumable module on the printer first determines whether the identification unit A is in contact with the electrical contact B of the main component through the IIC communication protocol. If they are in contact, the printer reports an error. If they are not in contact, the printer notifies the drive gear in the drive module 103 inside the printer to drive the transmission gear 1021 to rotate. The rotation of the transmission gear 1021 pushes the bracket module 101 to move, so that the identification unit A moves from the initial position to the target position, making the identification unit A in contact with the electrical contact B of the main component. The consumable module on the printer then determines whether the identification unit A is in contact with the electrical contact B of the main component a second time through the IIC communication protocol. If the identification unit A is in contact with the electrical contact B of the main component, the printer is ready and can print normally. If the identification unit A is not in contact with the electrical contact B of the main component, the printer reports an error. The printer can also report error messages to a data display module (e.g., the printer's display panel), which displays error messages when the identification unit A is not in contact with the electrical contact B of the main component. The identification unit A can remain in contact with the electrical contact B of the main component, or the second thrust mechanism 202 can act on the reset structure 1016 of the box and apply force to separate the identification unit A from the electrical contact B of the main component.

[0202] During the shutdown process of the image forming apparatus, such as Figure 11 , Figures 12A-12C As shown, if the identification unit A contacts the electrical contact B of the main component, the second thrust mechanism 202, in conjunction with the reset structure 1016, can separate the identification unit A from the electrical contact B of the main component, as described above, allowing the identification unit A to return to its initial position. When the image forming apparatus is powered on, it restarts the transmission mechanism within the cartridge 100, enabling the identification unit A to re-contact the electrical contact B of the main component, thus facilitating communication between the identification unit A and the electrical contact B of the main component. The image forming apparatus then uses the electrical contact B of the main component to detect the identification unit A, determining whether the cartridge 100 is properly installed and further verifying whether the cartridge 100 is the original cartridge for the image forming apparatus.

[0203] The following uses a printer as an example to describe the printer's detection process for the cartridge installation status during the printer's startup process. Figure 13 A flowchart illustrating the printer detection cartridge installation status according to an embodiment of this application is shown. Figure 13 As shown, the method for detecting the installation status of the printer cartridge in this embodiment includes the following steps:

[0204] Step 1301: Power on the printer. Before powering on the printer, the printer cartridge can be installed inside the printer, such as... Figure 7A and Figure 7B As shown, the identification unit A is separated from the electrical contact B of the main component, and the identification unit A is in the initial position.

[0205] Step 1302: The identification unit installed on the printer control box is reset / or the identification unit is in a reset state when the box is installed on the printer. For example... Figure 11 , Figures 12A-12C As shown, the reset of identification unit A here can be understood as the process of identification unit A returning from the target position to the initial position. For example, after the printer completes a printing operation, the identification unit A of the printer control operation box 100 is reset, causing identification unit A to separate from the electrical contact B of the main component. Alternatively, the position of identification unit A in the initial position can be understood as a gap existing between identification unit A and the electrical contact B of the main component after the box 100 is installed in the printer, i.e., the identification unit A and the electrical contact B of the main component are in a separated state.

[0206] Step 1303: The printer uses the IIC communication protocol to detect for the first time whether the electrical contact B of the main component is in contact with the identification unit A.

[0207] like Figure 11 , Figures 12A-12C As shown, after executing step 1302, the electrical contact B of the main component will not make contact with the identification unit A. Therefore, if the printer detects the electrical contact B of the main component making contact with the identification unit A for the first time within a non-preset time period, it indicates that the identification unit A is abnormal. At this time, it indicates that the cartridge 100 is not installed in the printer properly, or the cartridge 100 is not the original cartridge of the image forming apparatus. Step 1304 can be executed. When the printer detects for the first time that the electrical contact B of the main component is not in contact with the identification unit A (i.e., separated), it indicates that the identification unit is normal and the identification unit is in the initial position. Step 1305 can be executed.

[0208] Step 1304: The printer determines that the identification unit and the printer are mismatched. When identification unit A is mismatched with the printer, the printer can generate an error status and display an error message on the printer's control panel. For example, as follows... Figure 11 As shown, the error status can be displayed on the panel display area of ​​the printer. This indicates that the cartridge 100 is not installed properly in the printer, or that the cartridge 100 is not the original cartridge of the image forming device.

[0209] Step 1305: The printer controls the drive motor of the drive shaft to reverse, so as to control the drive shaft to drive the transmission mechanism to push the recognition unit.

[0210] like Figure 11 , Figures 12A-12CAs shown, the drive shaft 105 can rotate clockwise or counterclockwise. When the transmission mechanism inside the box 100 pushes the identification unit A, it can push the identification unit A from the initial position to the target position within a preset time period, so that the identification unit makes contact with the electrical contacts of the main component.

[0211] Step 1306: The printer checks for the second time, within a preset time, whether the electrical contact B of the main component is in contact with the identification unit A via the IIC communication protocol.

[0212] like Figure 11 , Figures 12A-12C As shown, if the printer does not receive the contact information between the electrical contact B of the main component and the identification unit A detected for the first time, it means that the printer can control the transmission mechanism to push the identification unit A to contact the electrical contact B of the main component within a preset time period, and can execute steps 1305 and 1306.

[0213] like Figure 11 As shown, if the printer receives the first detection of the electrical contact B of the main component making contact with the identification unit A, it indicates that the identification unit A and the printer are not compatible.

[0214] Step 1307: Printer Ready. After the printer is ready, if you need to perform printer operations, you can proceed to step 1308.

[0215] Step 1308: The printer performs the printing operation. After the printing operation is completed, as follows: Figure 11 , Figures 12A-12C As shown, if the user needs to replace the cartridge 100, they can open the printer front door (i.e., the openable and closable compartment door of the printer mounting cartridge 100).

[0216] Step 1309: Manually pull out the drawer of the mounting box to reset the identification unit. (Example:) Figure 11 , Figures 12A-12C As shown, after the identification unit A retracts, closing the printer's front door allows you to return to step 1303. When the printer is not in use, step 1310 can be selectively executed.

[0217] Step 1310: Turn off the printer. If the user turns the printer back on, they can return to step 1301.

[0218] It should be noted that, as Figure 11 , Figures 12A-12C As shown, the box in this embodiment may further include an end cover 106. When the identification unit A is in the initial position, the support module 101, the first thrust mechanism 102, the drive module 103 and the identification unit A are disposed inside the end cover 106; when the identification unit A is in the target position, the identification unit A is located outside the end cover 106.
