Description

Technical Field

[0001] This application relates to the field of image forming technology, and more specifically to a processing box. Background Technology

[0002] Image forming equipment is a common piece of modern office equipment, and processing cartridges are common consumables for image forming equipment. Different image forming equipment requires different processing cartridges, and different processing cartridges are compatible with different image forming equipment.

[0003] In some processing boxes, such as the patent with publication number CN113495459A, such as Figure 1 As shown, the image forming apparatus 100 includes a guide frame 70, and the developing cartridge 20 (equivalent to a processing cartridge) contains a first holder 34. The first holder 34 is mounted with a developing memory 31 of the developing cartridge 20, used to hold the developing memory 31 and its first electrical contact surface 33. When the developing cartridge 20 is installed in the image forming apparatus 100, the first holder 34, guided by the guide frame 70, moves upward simultaneously in the second and third directions shown in the figure, thereby enabling the first electrical contact surface 33 on the developing memory 31 of the first holder 34 to electrically connect with the main electrical contact 15 in the image forming apparatus 100.

[0004] The first holder 34 is guided to move using the guide frame 70 in the image forming apparatus 100. If the guide frame 70 is damaged or has errors, the first holder 34 may become stuck or damaged. Conversely, if the first holder 34 is damaged or has errors, the guide frame 70 may fail to guide the first holder 34 to move correctly. Furthermore, the friction generated between the guide frame 70 and the first holder 34 during movement can easily damage the first holder 34. Utility Model Content

[0005] This application provides a retainer structure that is completely different from the prior art, which can effectively avoid the impact of damage to one of the retainer and the image forming device on the other, as well as damage caused by friction between the guide frame and the retainer in the image forming device.

[0006] The utility model provides a kind of processing box, which is detachably installed in an image forming device, the processing box comprises: a housing;A chip mounting unit is arranged on the housing, the chip mounting unit includes a chip carrier portion and a recovery portion that can move relative to the housing, the chip carrier portion is used to install a memory chip, and the recovery portion is used to move the chip carrier portion from a working position to an initial position;When the processing box is installed in the image forming device, a trigger unit in the image forming device contacts the chip mounting unit, and then causes the chip carrier portion in the chip mounting unit to move from the initial position to the working position.

[0007] Therefore, the processing box provided by the embodiments of the present application moves the chip mounting unit by contacting the chip mounting unit with the trigger unit in the image forming device, rather than guiding the movement of the chip mounting unit by the guide rail or guide frame in the image forming device, i.e., adopts a completely different way from the guide rail to move the chip mounting unit (equivalent to the holder), which can effectively avoid the problems caused by the guide rail.

Similarly, the terms "a," "one," or "the" do not indicate a quantity limitation, but rather indicate the presence of at least one. Likewise, the terms "including" or "comprising" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0017] The terms "connection" or "linking" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The steps preceding or following each other in the method of this utility model embodiment are not necessarily performed precisely in sequence. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0018] like Figure 1 As shown in patent publication CN113495459A, the image forming apparatus 100 includes a guide frame 70 for guiding the movement of a first holder 34 on the developing cartridge 20. The first holder 34 houses the developing memory 31 of the developing cartridge 20 and holds the developing memory 31 and its first electrical contact surface 33. When the developing cartridge 20 is installed in the image forming apparatus 100, the first holder 34, guided by the guide frame 70, moves upwards simultaneously in the second and third directions shown in the figure, thereby enabling the first electrical contact surface 33 on the developing memory 31 of the first holder 34 to electrically connect with the main electrical contact 15 in the image forming apparatus 100.

[0019] As Figure 2 shown in the patent with publication number CN113495459A, due to the action of the first boss 41 and the through hole 354, the first retainer 34 can move in the second direction and the third direction. When the developing cartridge 20 is installed into the image forming apparatus 100, the first retainer 34 moves along one side of the second direction and one side of the third direction under the guiding action of the guide frame 70 in the image forming apparatus 100, so that the first electrical contact surface 33 on the developing storage 31 on the first retainer 34 can be electrically connected with the main body electrical contact 15 in the image forming apparatus 100. And when the developing cartridge 20 is taken out of the image forming apparatus 100, the first retainer 34 moves back to the original position along the other side of the second direction and the other side of the third direction under the action of gravity.

[0020] And the utility model provides a kind of processing box, the chip mounting unit in the processing box can be better and more stably electrically connected with main body electrical contact 15 in image forming apparatus 100, and it is completely different from the first retainer 34 in the developing cartridge 20 disclosed in the above patent, but still can realize adaptation same image forming apparatus 100.

[0021] The utility model provides a kind of processing box, the processing box is detachably installed in image forming device, wherein, image forming device (Image Forming Apparatus) is a kind of equipment for generating image, is widely used in printing, copying, scanning and other fields.It converts digital or analog signal into visual image by a series of optical, mechanical and electronic technology.The common image forming device includes printer, copier, multifunctional machine, scanner etc.

[0022] Figure 3 The overall structural diagram of the processing box provided by an embodiment of the utility model is shown in Figure 3 As shown in the figure, the processing box 200 includes a shell 1 and a chip mounting unit 2, the chip mounting unit 2 is arranged on the shell 1, the chip mounting unit 2 includes a chip carrying part 21 and a restoring part 22 which can move relative to the shell 1, the chip carrying part 21 is used for installing a storage chip 3, and the restoring part 22 is used for moving the chip carrying part 21 from an initial position to a working position; when the processing box 200 is installed in an image forming device, a trigger unit in the image forming device contacts the chip mounting unit 2, and then promotes the chip carrying part 21 in the chip mounting unit 2 to move from the initial position to the working position.

[0023] Thus the processing box 200 provided by the utility model, as long as the trigger unit in the image forming device contacts the chip mounting unit 2 in the processing box 200, the chip bearing part 21 in the chip mounting unit 2 can be gradually prompted to move from the initial position to the working position, so that the storage chip 3 in the chip bearing part 21 can be electrically connected with the image forming device. That is, the processing box 200 provided by the utility model utilizes the trigger unit in the image forming device to realize the movement of the chip bearing part 21. It should be noted that when the processing box 200 provided by the utility model is installed in the image forming device, the chip mounting unit 2 will not contact the guide structure (for reference to the guide frame 70 in the image forming equipment 100 in Figure 1 the utility model), and will not be guided by the guide structure, and the second guided structure in the chip mounting unit 2 will not be matched with the guide structure of the image forming device.

[0024] Thus the movement of the chip bearing part 21 in the processing box 200 provided by the utility model is based on the triggering of the trigger unit in the image forming device, rather than the guiding effect of the guide structure (for reference to the guide frame 70 in the image forming equipment 100 in Figure 1 the utility model) in the image forming device. Therefore the chip mounting unit 2 and the guide structure in the image forming device will not be damaged due to the friction caused by their mutual movement.

[0025] Since the guide structure in the image forming device is located in the relatively internal position of the image forming device and is not easy to touch and maintain, if the guide structure is damaged, the maintenance cost is very high. The trigger unit used in the present application is located in the relatively conspicuous and easy-to-maintain position of the same image forming device, and even if it is damaged, it is easy to be repaired, and the maintenance cost is obviously much lower.

[0026] Therefore the processing box 200 provided by the utility model not only provides a completely different chip mounting unit 2, but also can reduce the damage of the processing box 200 and the image forming device, and the maintenance cost is also lower.

[0027] The initial position refers to the position of the chip bearing part 21 relative to the shell 1 when the processing box 200 is not installed in the image forming device; the working position refers to the position of the chip bearing part 21 relative to the shell 1 when the processing box 200 is installed in the image forming device and the storage chip 3 in the chip bearing part 21 is electrically connected with the image forming device.

[0028] As shown in Figure 3 , the chip bearing part 21 is located at the initial position; as shown in Figure 4 , the chip bearing part 21 is located at the working position.

[0029] As shown in Figure 3 andFigure 4 As shown, the process cartridge 200 further comprises a developing roller 4 extending along the first direction X.

[0030] As mentioned above, the chip carrying portion 21 is movable from the initial position to the working position. In some embodiments, the chip carrying portion 21 is moved in such a way that the chip carrying portion 21 rotates about a point from the initial position to the working position. In this case, the axis of rotation of the chip carrying portion 21 is parallel to the first direction X, whereby the plane in which the chip carrying portion 21 rotates is parallel to the first end face, which is generally perpendicular to the first direction X. In some cases, the first end face is the end face of the side end of the process cartridge 200.

[0031] The applicant has found in the development process that when the process cartridge 200 is installed in the image forming apparatus, the gap between the process cartridge 200 and the image forming apparatus is limited, especially in the first direction X. Therefore, the axis of rotation of the chip carrying portion 21 is parallel to the first direction X, which can effectively save the space of the process cartridge 200 in the first direction X without sacrificing the space occupied by other structures of the process cartridge 200.

[0032] Further, in some embodiments, as shown in Figs. 1 and 2, the chip mounting unit 2 further comprises a linkage portion 23 and a receiving portion 24, the receiving portion 24 is connected with the linkage portion 23, the linkage portion 23 is connected with the chip carrying portion 21, and the receiving portion 24 is used to contact with a triggering unit in the image forming apparatus; when the process cartridge 200 is installed in the image forming apparatus, the triggering unit in the image forming apparatus contacts with the receiving portion 24 of the chip mounting unit 2 and moves, thereby driving the chip carrying portion 21 to move from the initial position to the working position through the linkage portion 23. Figure 3 Figure 5 Further, in some embodiments, as shown in Figs. 1 and 2, the chip mounting unit 2 further comprises a linkage portion 23 and a receiving portion 24, the receiving portion 24 is connected with the linkage portion 23, the linkage portion 23 is connected with the chip carrying portion 21, and the receiving portion 24 is used to contact with a triggering unit in the image forming apparatus; when the process cartridge 200 is installed in the image forming apparatus, the triggering unit in the image forming apparatus contacts with the receiving portion 24 of the chip mounting unit 2 and moves, thereby driving the chip carrying portion 21 to move from the initial position to the working position through the linkage portion 23.

[0033] In some embodiments, the linkage portion 23 is provided with a pivot structure 231, so that the linkage portion 23 can rotate about the pivot structure 231. Since the chip carrying portion 21 is connected with the linkage portion 23, the chip carrying portion 21 can also rotate about the pivot structure 231. When the receiving portion 24 contacts with the triggering unit in the image forming apparatus and moves, the movement of the receiving portion 24 drives the linkage portion 23 to rotate about the pivot structure 231, thereby driving the chip carrying portion 21 to move from the initial position to the working position.

[0034] ​In some embodiments, the restoring portion 22 is arranged between the housing 1 and the linkage portion 23; or, the restoring portion 22 is arranged between the housing 1 and the receiving portion 24. When the process cartridge 200 is removed from the image forming apparatus, the restoring portion 22 causes the linkage portion 23 or the receiving portion 24 to return to the corresponding original position (here, the corresponding original position refers to the position of the linkage portion 23 or the receiving portion 24 relative to the housing 1 when the process cartridge 200 is not installed in the image forming apparatus), thereby causing the chip carrier portion 21 to return to the original position.

[0035] Further, in some embodiments, the restoring portion 22 is configured to cause the chip carrier portion 21 to return to the original position by using elastic force. For example, the restoring portion 22 can be an elastic member, one end of which is arranged on the housing 1 and the other end of which is arranged on the receiving portion 24 or the linkage portion 23. The elastic member refers to a member that can be elastically deformed when an external force is applied and can return to the original state when the external force is removed. Due to this characteristic of the elastic member, the chip carrier portion 21 can be caused to quickly react and return to the original position. In other embodiments, the restoring portion 22 can also be configured to cause the chip carrier portion 21 to return to the original position by using gravity. For example, a space for free movement can be left so that the chip carrier portion 21 can return to the original position under the action of gravity.

[0036] Further, in some embodiments, the elastic member is a spring, one end of which is arranged on the housing 1 and the other end of which is arranged on the receiving portion 24 or the linkage portion 23. Since the spring can have a stronger elastic deformation force than other elastic members and the stored energy can be quickly released when the external force is removed, the spring as the elastic member can simply and efficiently cause the chip carrier portion 21 to return to the original position.

[0037] The elastic member can also be an elastic diaphragm, an elastic wire, or the like.

[0038] Further, in some embodiments, the elastic member is arranged so that the elastic stretching direction of the elastic member is parallel to the first end surface, so that the receiving portion 24 or the linkage portion 23 is moved on the first end surface by the elastic force of the elastic member, thereby causing the chip carrier portion 21 to rotate so that the plane on which the chip carrier portion 21 is arranged is parallel to the first end surface.

[0039] In some embodiments, as shown in FIG. 6, the receiving portion 24 is arranged on the linkage portion 23. In this case, the linkage portion 23 is arranged so that the elastic stretching direction of the elastic member is parallel to the first end surface, so that the receiving portion 24 is moved on the first end surface by the elastic force of the elastic member, thereby causing the chip carrier portion 21 to rotate so that the plane on which the chip carrier portion 21 is arranged is parallel to the first end surface. Figure 5As shown, at least one of the linkage portion 23, the chip carrying portion 21 and the receiving portion 24 is further provided with a limiting structure 25, and the housing 1 is provided with a limiting structure 11, and the limiting structure 25 cooperates with the limiting structure 11 when the chip carrying portion 21 moves. The cooperation of the limiting structure 25 and the limiting structure 11 limits the moving range of the chip carrying portion 21, so that the chip carrying portion 21 does not continue to move when the chip carrying portion 21 moves to the working position, thereby facilitating the stable electrical connection between the storage chip 3 on the chip carrying portion 21 and the image forming device.

[0040] Further, in some embodiments, the limiting structure 11 on the housing 1 can be a limiting wall, and the limiting structure 25 can be a protrusion or a contact surface on at least one of the linkage portion 23, the chip carrying portion 21 and the receiving portion 24. When the protrusion or the contact surface contacts the limiting wall, the limiting wall timely stops and limits the movement of at least one of the linkage portion 23, the chip carrying portion 21 and the receiving portion 24.

[0041] In some embodiments, the receiving portion 24 is fixedly connected with the linkage portion 23, and the linkage portion 23 is fixedly connected with the chip carrying portion 21, so that when the receiving portion 24 contacts and moves with the triggering unit in the image forming device, the movement of the receiving portion 24 can quickly drive the linkage portion 23 to rotate around the rotating shaft structure 231, and in turn quickly drive the chip carrying portion 21 to move from the initial position to the working position. Further, in some embodiments, the linkage portion 23, the chip carrying portion 21 and the receiving portion 24 are integrally formed.

[0042] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
