Description

[0001] This utility model is a divisional application filed in response to the parent application filed on July 19, 2024, with application number 202421730139.7 and invention title "Processing Box".

[0002] This application claims priority to a prior Chinese application filed on July 19, 2023, with application number 202321913199.8 and entitled "Processing Box", all contents of which are cross-referenced in this application. Technical Field

[0003] This utility model relates to the field of electrophotographic imaging, and more particularly to a processing box that can be detachably installed in an electrophotographic imaging device. Background Technology

[0004] A drawer-type imaging device is provided, which has a tray that can be pulled towards the user and pushed away from the user. When the tray is pulled out, the processing box is first installed on the tray, then the tray is pushed into the imaging device, and finally the door is closed. The processing box uses a charging component rotatably disposed therein to charge the surface of the photosensitive element in contact with the charging component, and forms text or images on the imaging medium through exposure, development, transfer and other steps. Therefore, the processing box is also provided with charging electrodes for receiving power from the imaging device and supplying it to the charging component.

[0005] The imaging device is also equipped with a top plate that is linked to the door cover. The top plate is also equipped with a power output component that can make electrical contact with the charging electrode. As the door cover closes, the top plate moves downward and abuts against the processing box. The power output component makes electrical contact with the charging electrode, which finally positions the processing box in the imaging device. At the same time, the charging electrode can receive the power output from the power output component. Conversely, when the door cover is opened, the top plate moves upward away from the processing box, the tray can be pulled out, and the charging electrode loses contact with the power output component.

[0006] Typically, the processing box also includes a chip capable of establishing a communication connection with the imaging device. A contact pin, which can electrically contact the chip, is mounted on the top plate. This contact pin is retractable; as the top plate moves downwards, the contact pin abuts against the chip to achieve electrical contact. To simplify the internal circuitry of the imaging device, the chip and charging electrode are positioned at the same longitudinal end of the processing box. When the processing box reaches the predetermined installation position with the tray, the electrical contact portion of the chip for electrical contact with the contact pin and the charging electrode are both fixed upwards (towards the top plate). This allows for simultaneous contact between the contact pin and the electrical contact portion, as well as contact between the power output component and the charging electrode.

[0007] Generally, the processing box is also equipped with a conductive component that can be electrically connected to the imaging device. The conductive component is installed on a support member located at the end of the processing box. The conductive component can receive power provided by the imaging device and supply it to the developing component, the powder feeding component in contact with the developing component, and the powder discharging blade in contact with the developing component, which are rotatably arranged in the processing box. However, the existing conductive component is installed from the outside of the support member (the side away from the developing component) and requires multiple fasteners, which makes the structure complex and inconvenient to assemble.

[0041] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0042] [Overall structure of the processing box]

[0043] Figure 1 This is a perspective view of the processing box involved in this utility model.

[0044] The processing box C can be detachably installed into the imaging device, which includes the aforementioned drawer-type tray and a top plate that moves with the door cover. The top plate is equipped with a movable stylus 95 and a power output component 96 (e.g., Figure 4As shown, when the processing box C arrives inside the imaging device along with the tray, the top plate moves downward and comes into contact with the processing box C while the door is closed. Therefore, the stylus 95 and the power output component 96 can simultaneously contact the corresponding components in the processing box C. For a detailed description of the imaging device, please refer to Chinese invention patent application with publication number CN113574469A.

[0045] The processing cartridge C includes a first unit 100 and a second unit 200 connected together, and a first end cap 300 and a second end cap 400 located at the two longitudinal ends of the processing cartridge C. The first unit 100 and the second unit 200 can be connected together by the first end cap 300 and the second end cap 400, or by means such as pins or buckles. The first end cap 300 and the second end cap 400 can be part of the first unit 100 or the second unit 200, or they can be components independent of the first unit 100 or the second unit 200, as long as they can connect the first unit 100 and the second unit 200. Developing roller 11 (e.g. Figure 3 As shown, the photosensitive drum 21 is rotatably disposed in the first unit housing 1 of the first unit 100, and the photosensitive drum 21 is rotatably disposed in the second unit housing 2 of the second unit 200. When the processing cartridge C is working, the photosensitive drum 21 contacts the developing roller 11, and the developing roller 11 supplies the toner stored in the first unit 100 to the photosensitive drum 21.

[0046] For ease of description below, the side of the processing cartridge C in which the photosensitive drum 21 and the developing roller 11 are installed, pointing towards the side in which the photosensitive drum 21 and the developing roller 11 are not installed, is defined as the upper side, and the side opposite to the upper side is defined as the lower side. The processing cartridge C is installed on the tray of the imaging device from top to bottom in the vertical direction. The direction from the first unit 100 to the second unit 200 is defined as the front, and the side opposite to the front is defined as the rear. The side of the processing cartridge C that receives driving force from the imaging device is defined as the left side, and the side opposite to the left side is defined as the right side. The right side is the side that receives electricity. The left side may also be referred to as the driving end C1, and the right side may also be referred to as the non-driving end / conductive end C2. The first end cover 300 is installed on the driving end C1, and the second end cover 400 is installed on the non-driving end C2. The first driving force receiver (not shown) for receiving driving force for the developing roller 11 and the second driving force receiver (not shown) for receiving driving force for the photosensitive drum 21 are both exposed from the first end cover 300.

[0047] The developing roller 11 and the photosensitive drum 21 both extend in the left-right direction, which can also be referred to as the longitudinal direction. The front-back direction and the up-down direction intersect with the left-right direction. Preferably, the left-right direction, the front-back direction and the up-down direction are perpendicular to each other. After the processing box C is installed on the tray, the tray is pushed into the imaging device in the front-back direction.

[0048] The processing box C also includes a separation contact mechanism 5 located therein (such as... Figure 2 As shown), when the processing cartridge C is not needed in the imaging device, the separation contact mechanism 5 receives a separation force from the imaging device, forcing the developing roller 11 and the photosensitive drum 21 to separate from each other, thus suppressing contamination of the surface of the photosensitive drum 21 or deformation of the surface of the developing roller 11. The separation contact mechanism 5 is located near the longitudinal end of the processing cartridge C, and there can be one or more of them. Furthermore, the processing cartridge C also includes a reset member 16 (such as...) disposed between the first unit 100 and the second unit 200. Figure 2 As shown, when the separation force is applied to the processing cartridge C, the reset member 16 undergoes elastic deformation. When the separation force is removed, the reset member 16 releases its elastic force, and the developing roller 11 and the photosensitive drum 21 return to their contacting position.

[0049] Processing box C also includes a chip 7 for establishing a communication connection with the imaging device (such as...) Figure 2 As shown), the chip 7 includes a storage section (not shown) storing information of the processing box C and an electrical contact section 71 electrically connected to the storage section. The electrical contact section 71 and the storage section can be integrated on the same board or set separately, but the electrical contact section 71 always faces upward and is exposed to the top of the processing box C. When the door is closed, the electrical contact section 71 makes electrical contact with the contact pin 95.

[0050] Furthermore, the processing box C also includes a charging roller 24 rotatably disposed in the second unit housing 2 and a charging electrode assembly 8 for supplying power to the charging roller 24 (such as...). Figure 3 As shown, the charging electrode assembly 8 is used for electrical contact with the power output component 96. The charging roller 24 is rotatably supported by the bracket 26. The spring 25 is disposed between the bracket 26 and the second unit housing 2. The charging roller 24 is kept in contact with the photosensitive drum 21 by the pushing of the spring 25. The charging roller 24 includes a metal shaft 241 and a covering layer 242 covering the surface of the metal shaft 241. When the processing cartridge C is working, the metal shaft 241 receives power from the imaging device, so that the charging roller 24 charges the surface of the photosensitive drum 21. When the laser beam carrying imaging information irradiates the surface of the charged photosensitive drum 21, an electrostatic latent image is formed in the area to be imaged. Subsequently, the toner on the surface of the developing roller 11 develops the electrostatic latent image. In some embodiments, the charging electrode assembly 8 supplies power to the charging roller 24 by directly abutting against the metal shaft 241. In other embodiments, the bracket 26 can be made of conductive material, so that the charging electrode assembly 8 supplies power to the charging roller 24 by abutting against the spring 25 or the bracket 26. In the following description, the electrical connection between the charging electrode assembly 8 and the charging roller 24 includes any one of the three contact methods described above.

[0051] Preferably, the electrical contact 71 and the charging electrode assembly 8 are disposed at the non-driving end C2. On the one hand, this can prevent the vibration of the driving end C1 from causing instability in the electrical contact between the electrical contact 71 and the stylus 95 and the electrical contact between the charging electrode assembly 8 and the power output component 96. On the other hand, it can simplify the circuit complexity within the imaging device, so that the components in the imaging device used to supply power to the processing box C (such as the stylus 95 and the power output component 96 mentioned above) are all disposed at the non-driving end C2 of the processing box C.

[0052] In some embodiments, the positions of the electrical contact 71 and the charging electrode assembly 8 should not be limited. For example, the electrical contact 71 and the charging electrode assembly 8 may be disposed on any one of the first unit housing 1, the second unit housing 2, and the second end cover 400, respectively or together.

[0053] The following description uses the example of the electrical contact portion 71 and the charging electrode assembly 8 being simultaneously provided on the second end cover 400.

[0054] [Example 1]

[0055] Figure 2 This is a perspective view of the processing box according to Embodiment 1 of this utility model; Figure 3 This is a side view of the processing box according to Embodiment 1 of this utility model when a portion of its components are hidden, viewed from left to right in the left-right direction. Figure 4 This is a three-dimensional view of the top plate in the imaging device to which the processing box of this utility model is applicable; Figure 5A This is a simplified side view of the processing box according to Embodiment 1 of this utility model, viewed from left to right in the left-right direction before it comes into contact with the top plate. Figure 5B This is a simplified side view of the processing box according to Embodiment 1 of this utility model when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0056] Before describing the processing box C of this embodiment, the power output component 96 will be described first, such as... Figure 4 As shown, with the processing box C installed in the imaging device, the top plate 94 also has the above-mentioned up-down, left-right, and front-back directions. The stylus 95 and the power output component 96 are both exposed downwards. The number of stylus 95 corresponds to the number of electrical contacts 71 of the chip 7. The power output component 96 is a conductor that protrudes downwards from the top plate 94 and has a front conductive surface 962 facing forward, a rear conductive surface 961 facing backward, a left conductive surface 963 facing left, a right conductive surface 965 facing right, and a lower conductive surface 964 facing downward.

[0057] like Figure 3As shown, the charging electrode assembly A8 includes a power receiving part A81 for receiving power and a power transmitting part A82 for being electrically connected to the charging roller 24. The power receiving part A81 and the power transmitting part A82 are electrically connected. Preferably, the power receiving part A81 and the power transmitting part A82 are integrally formed. In this embodiment, the power receiving part A81 and the power transmitting part A82 are integrally formed from a conductive steel sheet.

[0058] Furthermore, such as Figure 2 As shown, the second end cover 400 is also provided with an electrical contact cavity 401. When the door cover of the imaging device is closed, at least the power receiving part A81 is located in the electrical contact cavity 401. In this embodiment, the power receiving part A81 is fixedly installed in the electrical contact cavity 401. Specifically, the power receiving part A81 is fixed on the front side of the electrical contact cavity 401.

[0059] Before the imaging equipment door is closed, the top plate 94 is in the position as follows: Figure 5A At the position shown, the top plate 94 is not in contact with the processing box C in the vertical direction, the stylus 95 is separated from the electrical contact 71, and the power output component 96 is also separated from the power receiving component A81. As the imaging device door closes, the top plate 94 gradually moves downward. When the door is fully closed, the top plate 94 comes into contact with the imaging device, the stylus 95 comes into contact with the electrical contact 71 and retracts into the top plate 94, at least a portion of the power output component 96 enters the electrical contact cavity 401, and the front conductive surface 962 comes into contact with the power receiving component A81. Finally, the electrical contact 71 and the stylus 95 are electrically connected, and the power receiving component A81 and the power output component 96 are also electrically connected. The electrical connection between the processing box C and the imaging device will also become stable. At the same time, by using the contact of the stylus 95 with the electrical contact 71, the processing box C can be stably positioned in the imaging device.

[0060] As a variation of this embodiment, the power receiving unit A81 can also be disposed on the rear side of the electrical contact cavity 401. When at least a portion of the power output member 96 enters the electrical contact cavity 401, the rear conductive surface 961 of the power output member 96 contacts the power receiving unit A81. At this time, the force that the power receiving unit A81 may exert on the power output member 96 will be forward. This method can also ensure that the electrical connection between the processing box C and the imaging device becomes stable.

[0061] As described above, when the door is closed and the top plate 94 abuts against the processing box C, at least a portion of the power output component 96 enters the electrical contact cavity 401, and the power receiving part A81 abuts against the side conductive surface (non-bottom conductive surface) of the power output component 96. The force that the power receiving part A81 may exert on the power output component 96 is backward, and the top plate 94 will only be subjected to the upward reaction force exerted by the electrical contact part 71 on the stylus 95. Therefore, the contact between the electrical contact part 71 and the stylus 95 and the contact between the power receiving part A81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device will also become stable.

[0062] [Example 2]

[0063] Figure 6 This is a perspective view of some components in the processing box according to Embodiment 2 of this utility model; Figure 7 This is a partial perspective view of the processing box after it comes into contact with the top plate according to Embodiment 2 of this utility model.

[0064] Compared with Embodiment 1, the contact position between the charging electrode assembly B8 and the power output component 96 is different in this embodiment, such as... Figure 6 As shown, the power receiving unit B81 is fixedly installed on the right side of the electrical contact cavity 401, as... Figure 7 As shown, when the top plate 94 comes into contact with the processing box C downwards, at least a portion of the power output component 96 enters the electrical contact cavity 401, the contact pin 95 is electrically connected to the electrical contact portion 71, and at the same time the right conductive surface 965 of the power output component 96 contacts the power receiving portion B81 to achieve electrical connection.

[0065] Similarly, in this embodiment, the force that the power receiving unit B81 may exert on the power output unit 96 is to the left, and the top plate 94 will only be subjected to the upward reaction force exerted by the electrical contact 71 on the stylus 95. Therefore, the contact between the electrical contact 71 and the stylus 95 and the contact between the power receiving unit B81 and the power output unit 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device will also become stable.

[0066] As a variation of this embodiment, the power receiving unit B81 can also be disposed on the left side of the electrical contact cavity 401. When at least a portion of the power output member 96 enters the electrical contact cavity 401, the left conductive surface 963 of the power output member 96 contacts. At this time, the force that the power receiving unit B81 may exert on the power output member 96 will be directed to the right. This method can also ensure that the electrical connection between the processing box C and the imaging device becomes stable.

[0067] [Example 3]

[0068] Figure 8 This is a perspective view of some components in the processing box according to Embodiment 3 of this utility model; Figure 9This is a simplified side view of the processing box involved in Embodiment 3 of this utility model when viewed from left to right in the left-right direction before contact with the top plate and after hiding some components; Figure 10 This is a simplified side view of the processing box according to Embodiment 3 of this utility model when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0069] As shown in the figure, the charging electrode assembly C8 in this embodiment includes a power receiving part C81, a power transmitting part C82, and a toggle member C83. The toggle member C83 is used to toggle the power receiving part C81, so that the power receiving part C81 changes from a first state where it cannot receive power to a second state where it can receive power. Thus, the power from the power output part 96 is transmitted to the charging roller 24 in sequence through the toggle member C83, the power receiving part C81, and the power transmitting part C82, or the power is transmitted to the charging roller 24 in sequence through the power receiving part C81 and the power transmitting part C82.

[0070] In this embodiment, the actuating member C83 is configured to rotate around a rotation axis. This rotation axis should not be restricted. For example, the rotation axis can be parallel to the left-right direction, parallel to the front-back direction, or parallel to the up-down direction. The power receiving part C81 and the power transmitting part C82 are configured as an integrally formed tension spring. The power receiving part C81 and the power transmitting part C82 are the two ends of the tension spring, respectively. The power receiving part C81 is connected to the actuating member C83, and the power transmitting part C82 is electrically connected to the charging roller 24.

[0071] In this embodiment, the rotation axis of the actuating member C83 is parallel to the left-right direction, and the actuating member C83 is made of a non-conductive material. As shown in the figure, the actuating member C83 includes a pressed part C831, a actuating part C832, and a rotating part C833, wherein the pressed part C831 and the actuating part C832 protrude from the rotating part C833. Before the door is closed, or before the top plate 94 abuts against the processing box C, the power receiving part C81 is pulled upward by the tension spring (power receiving part C81), and the pressed part C831 faces downward. Preferably, the pressed part C831 protrudes from the second unit housing 2. When the top plate 94 begins to abut against the processing box C, the pressed part C831 is pressed by the top plate 94 and rotates around the rotation axis. The pressed part C831 moves upward, and at the same time, the actuating part C832 drives the power receiving part C81 to move downward. When the door is fully closed, the pressed part C831 is pressed to the bottom by the top plate 94, and at least a portion of the power output part 96 enters the electrical contact cavity 40. 1. The actuating part C832 drives the power receiving part C81 to contact the power output part 96. At the same time, the stylus 95 is electrically connected to the electrical contact part 71. The power receiving part C81 can contact any one of the side conductive surfaces of the power output part 96 (including the front conductive surface 962, the rear conductive surface 961, the left conductive surface 963, and the right conductive surface 965). At this time, the force that the power receiving part C81 may apply to the power output part 96 is not upward. Therefore, the contact between the electrical contact part 71 and the stylus 95 and the contact between the power receiving part C81 and the power output part 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0072] It should be noted that the power receiving part C81 in this embodiment can also contact the lower conductive surface 964 of the power output part 96. In this case, although the force applied by the power receiving part C81 to the power output part 96 may be upward, the power receiving part C81 is one end of a tension spring. Therefore, even if the upward pressure applied by the power output part 96 to the power receiving part C81 is large, the power receiving part C81 can offset the large pressure by contracting upward, so that the contact between the power output part 96 and the power receiving part C81 will not weaken the electrical connection between the electrical contact 71 and the stylus 95. Therefore, in this case, the contact between the electrical contact 71 and the stylus 95 and the contact between the power receiving part C81 and the power output part 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0074] Figure 11 This is a perspective view of some components in the processing box according to Embodiment 4 of this utility model; Figure 12 This is a simplified side view of the processing box according to Embodiment 4 of this utility model when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0075] Compared to Embodiment 3, the actuating element D83 in this embodiment is made of metal. Therefore, in this embodiment, when the top plate 94 abuts against the processing box C, the actuating element D83 does not need to move the power receiving part D81 to contact the power output part 96. Instead, the actuating element D83 itself contacts the power output part 96, and then the actuating element D83 transmits power to the power receiving part D81. Preferably, the actuating part D832 of the actuating element D83 contacts the power output part 96. In this way, the movement path of the power receiving part D81 in the processing box C can be reduced, or even the power receiving part D81 does not need to move, as long as it is ensured that the power receiving part D81 can maintain good electrical contact with the movable actuating element D83.

[0076] Similar to Embodiment 3, when the top plate 94 abuts against the processing box C, at least a portion of the power output component 96 enters the electrical contact cavity 401, and the actuating component D83 can contact any conductive surface of the power output component 96. Preferably, the actuating portion D832 of the actuating component D83 contacts the side conductive surface of the power output component 96. Therefore, the contact between the electrical contact portion 71 and the stylus 95 and the contact between the power receiving portion D81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0077] [Example 5]

[0078] Figure 13A and Figure 13B These are simplified side views of the processing box involved in Embodiment 5 of this utility model, viewed from left to right before and after contact with the top plate.

[0079] In this embodiment, the charging electrode assembly E8 includes a power receiving part E81, a power transmitting part E82, and a toggle member E83. The power transmitting part E82 is electrically connected to the charging roller 24, and the toggle member E83 is used to switch the power receiving part E81 from a first state where it cannot receive power to a second state where it can receive power. Unlike embodiments three and four, at least a portion of the toggle member E83 in this embodiment is configured as a rack that can slide in the up-down direction.

[0080] As shown in the figure, the actuating element E83 includes a rack E831, an actuating part E832, and a rotating part E833. The rack E831 extends in the vertical direction, and the actuating part E832 protrudes from the rotating part E833. The rack E831 and the rotating part E833 are provided with teeth that can mesh with each other. At the same time, the power receiving part E81 is connected to the actuating element E83 / actuating part E832, and the power transmitting part E82 is electrically connected to the charging roller 24.

[0081] According to the descriptions in Embodiments 3 and 4, the actuating part E832 can be made of either a conductive or non-conductive material. Preferably, when the top plate 94 is not in contact with the processing box C, the rack E831 protrudes upwards from the second end cover 400 / second unit housing 2. As the top plate 94 moves downwards towards the processing box C, the upper end of the rack E831 begins to be abutted by the top plate 94, causing the rack E831 to move downwards. Subsequently, the rotating part E833 rotates in the direction shown by r5, and the actuating part E832 itself, or the actuating part E832 driving the power receiving part E81, moves upwards. Figure 13B As shown, when the top plate 94 presses the rack E831 to its lowest position, at least a portion of the power output component 96 enters the electrical contact cavity 401. The actuating part E832 drives the power receiving part E81 to contact the power output component 96, or the actuating part E832 itself contacts the power output component 96. At the same time, the stylus 95 is electrically connected to the electrical contact part 71. The power receiving part E81 / actuating part E832 can contact any conductive surface of the power output component 96. Therefore, the contact between the electrical contact part 71 and the stylus 95 and the contact between the power receiving part E81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0082] [Example 6]

[0083] Figure 14A and Figure 14B These are simplified side views of the processing box according to Embodiment Six of this utility model, viewed from left to right before and after contact with the top plate.

[0084] Compared with Embodiment 5, in this embodiment, the actuating part F832 of the actuating member F83 is also configured as a rack, the rotating part E833 is located between the rack E831 and the rack E832, the actuating part F832 can be made of either a conductive material or a non-conductive material, the power receiving part F81 is connected to the rack F832, and the rack F832 is used to switch the power receiving part F81 from a first state where it cannot receive power to a second state where it can receive power. As the top plate 94 approaches the processing box C, at least a portion of the power output component 96 gradually enters the electrical contact cavity 401, the rack E831 gradually moves downward, and through the rotating part E833, the rack E832 gradually moves upward. Finally, the power receiving part E81 contacts the power output component 96, or the rack E832 itself contacts the power output component 96. At the same time, the stylus 95 is electrically connected to the electrical contact part 71. The power receiving part F81 / toggle part F832 can contact any conductive surface of the power output component 96. Therefore, the contact between the electrical contact part 71 and the stylus 95, and the contact between the power receiving part F81 and the power output component 96, can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0085] As a variation of the above embodiment, at least a portion of the separation contact mechanism 5 can also serve as the toggle member. During the movement of the top plate 94 toward the processing box C, the top plate 94 interacts with the separation contact mechanism 5, thereby forcing at least a portion of the separation contact mechanism 5 to switch the power receiving section from a first state where it cannot receive power to a second state where it can receive power.

[0088] In this embodiment, the same components as in the above embodiments are numbered the same.

[0089] like Figures 15-19 As shown, the first unit 100 also includes a powder feeding roller 12 and a powder discharging blade 13 that are in contact with the developing roller 11. The powder feeding roller 12 is rotatably disposed in the first unit housing 1, and the powder discharging blade 13 is used to make the toner carried on the surface of the developing roller 11 evenly distributed.

[0090] The processing cartridge C also includes a conductive element 6, which receives power from the imaging device to supply power to the developing roller 11, the powder feeding roller 12, and the powder exiting blade 13. Furthermore, the conductive element 6 is simultaneously connected to the developing roller 11, the powder feeding roller 12, and the powder exiting blade 13 to simultaneously supply power to them, thus reducing the number of components. Further, the conductive element 6 is located at the non-driving end C2 of the processing cartridge C, with a portion of it exposed through a second end cap 400 for electrical connection to the power supply components of the imaging device. Further, the conductive element 6 is located on a non-driving end support 500, which is situated at the non-driving end C2 and is at least partially covered by the second end cap 400.

[0091] Furthermore, such as Figure 17A and Figure 17BAs shown, the non-drive end support 500 is used to connect with the conductive element 6 to install the conductive element 6. The non-drive end support 500 is provided with multiple connecting portions. Specifically, the non-drive end support 500 includes a first connecting portion 503, a second connecting portion 504, a third connecting portion 505, a fourth connecting portion 506, and a fifth connecting portion 507, which are respectively connected with the conductive element 6. The first connecting portion 503, the second connecting portion 504, the third connecting portion 505, and the fourth connecting portion 506 are located on the inner side 501 of the non-drive end support 500, and the fifth connecting portion 507 is located on the outer side 502 of the non-drive end support 500. The inner side 501 is the side of the non-drive end support 500 that is closer to the developing roller 11 or the powder feeding roller 12 in the left-right direction, and the outer side 502 is the side of the non-drive end support 500 that is farther away from the developing roller 11 or the powder feeding roller 12 in the left-right direction. The first connecting portion 503 and the second connecting portion 504 are formed as grooves / through holes recessed from the inner side 501 toward the direction away from the developing roller 11. The first connecting portion 503 and the second connecting portion 504 can be used to support the developing roller 11 and the powder feeding roller 12, respectively. The first connecting portion 503 and the second connecting portion 504 can also be used to connect with the conductive member 6. The third connecting portion 505 and the fourth connecting portion 506 are preferably positioning posts extending to the left from the inner side 501 of the non-driving end support member 500. The third connecting portion 505 and the fourth connecting portion 506 are used to position the conductive member 6. Therefore, the third connecting portion 505 and the fourth connecting portion 506 are formed as at least part of the positioning mechanism, which is used to position the conductive member 6. The fifth connecting portion 507 is preferably a through hole extending in the left-right direction, used to expose a part of the conductive member 6 for electrical connection with the imaging device.

[0092] like Figure 18A and Figure 18BAs shown, the conductive element 6 includes a power input section 61, a power output section 62, and a conductive section 63 connecting the power input section 61 and the power output section 62. The power input section 61 is used to connect with the imaging device. Further, the power input section 61 is used to cooperate with the fifth coupling section 507 and is exposed from the fifth coupling section 507 to connect with the imaging device to receive power. The power output section 62 is used to connect with the developing roller 11, the powder feeding roller 12, and the powder exiting blade 13 and output power. The conductive element 6 is also provided with a first coupling section 64 and a second coupling section 65 that are coupled with the non-drive end support member 500. The first coupling section 64 is used to cooperate with the third coupling section 505, and the second coupling section 65 is used to cooperate with the fourth coupling section 506. The power input section 61 is configured to cooperate with the fifth coupling section 507 so that the conductive element 6 is mounted on the non-drive end support member 500. Furthermore, the power output section 62 includes a first output section 621, a second output section 622, and a third output section 623. The first output section 621 is used to connect with the powder discharge blade 13, the second output section 622 is used to connect with the first connecting section 503, and the third output section 623 is used to connect with the second connecting section 504. Furthermore, the second output section 622 extends to the first connecting section 503 to contact the developing roller 11, and the third output section 623 extends to the second connecting section 504 to contact the powder feeding roller 12.

[0093] like Figure 19 As shown, the conductive component 6 is installed from the inner side 501 of the non-drive end support 500. The cooperation between the third joint 505 and the first joint 64 and the cooperation between the fourth joint 506 and the second joint 65 enables the conductive component 6 to be positioned and installed. In the left-right direction, the conductive component 6 is abutted by at least one of the powder discharge blade 13, the developing roller 11 and the powder feeding roller 12 to prevent the conductive component 6 from falling off. Therefore, the conductive component does not need to be provided with multiple fasteners, which can simplify the installation and simplify the structure of the processing box C.

[0094] [Example 8]

[0095] Figure 20 This is a schematic diagram of the hidden components of the processing box according to Embodiment 8 of this utility model; Figure 21 This is a perspective view of the processing box involved in Embodiment 8 of this utility model when viewed from the left-right direction after being cut along a plane parallel to the vertical direction.

[0096] like Figure 20 , Figure 21As shown, the first unit 100 includes a toner hopper 100a for containing toner and a developing hopper 100b for containing a developing roller 11 and a toner delivery roller 12. A toner outlet partition 100c is provided between the toner hopper 100a and the developing hopper 100b. A toner outlet 100d is formed on the toner outlet partition 100c. The toner is transported to the developing hopper 100b through the toner outlet 100d, thereby supplying it to the photosensitive drum 21. Before use, the toner outlet 100c is sealed by a sealing element 16. Furthermore, the space of the toner hopper 100a is larger than the space of the developing hopper 100b. The sealing element 16 is welded to the side of the toner outlet partition 100c away from the developing roller 11 and the toner delivery roller 12. That is, the sealing element 16 is welded to the side of the toner outlet partition 100c facing the toner hopper 100a. Because the space of the toner hopper 100a is larger, the difficulty of welding the sealing element 16 is reduced, and the design freedom is also improved. A portion of the seal 16 is exposed from the end of the processing cartridge C. When the processing cartridge C is in use, the seal 16 can be pulled out from the outside of the processing cartridge C. Compared with the prior art, where the seal 16 is welded to the side of the powder outlet partition 100c near the developing roller 11 and the powder feeding roller 12, this embodiment can avoid interference between the seal 16 and the powder feeding roller 12 or the developing roller 11.

[0097] Furthermore, the first unit 100 is provided with a toner filling port 14 and a sealing cap 15 for sealing the toner filling port 14. The toner filling port 14 is located on the upper side of the sealing member 16. The toner filling port 14 can be used to add toner. In this embodiment, the toner filling port 14 is located at the non-driving end C2 of the processing box C.

[0098] In this embodiment, the first unit housing 1 includes a face cover 1a and a main body 1b that are joined together. The toner cartridge 100a and the developing cartridge 100b are formed between the face cover 1a and the main body 1b. During assembly, the sealing element 16 can be welded first, with one end of the sealing element 16 extending outside the processing cartridge C. Then, the face cover 1a of the first unit housing 1 is welded, so that the face cover 1a and the main body 1b are integrated. Finally, toner is filled through the toner filling port 14. When using the processing cartridge C, the sealing element 16 is first removed. Therefore, there is more operating space when welding the sealing element 16, which can reduce the welding difficulty of the sealing element 16 and improve the design freedom.
