Description

Technical Field

[0001] The present invention relates to an image forming device, and in particular to a developing device. Background Art

[0002] The developer cartridge is a common printing consumable for laser printers. Different developer cartridges have different models and specifications, and are compatible with different printer models. Therefore, the printer needs to test the model and specifications of the developer cartridge to confirm whether it can be adapted. In the prior art, chips, detection gears and other methods are commonly used for detection. However, chips are expensive, and high costs will lead to an increase in the price of developer cartridges. The detection gear is a mechanical structure that can completely replace the chip, and also provide some information to partially replace the chip, reducing the amount of information stored in the chip, thereby reducing the cost of the chip.

[0003] The existing detection gear is provided with a plurality of protrusions. When the detection gear rotates, the plurality of protrusions touch the detection rod in the main component of the image forming device, so that the image forming device judges the model and specification of the developing box according to the number of times the detection rod is touched.

[0004] However, this detection method is relatively simple, and with the continuous expansion of the developer cartridge product line, there are many models of developer cartridges. The developer cartridges are detected by having multiple protrusions touch the detection rod, and the number of protrusions that need to be set is increasing. Due to the existence of manufacturing tolerances, the more protrusions there are, the easier it is for detection to go wrong, resulting in the problem that the developer cartridge cannot be correctly detected by the image forming device. Summary of the invention

[0005] According to one aspect of the present invention, there is provided a developing device detachably mounted on a main assembly of an image forming device having a detection component, comprising:

[0006] Box body;

[0007] A first protective cover, which is disposed at one end of the box body;

[0008] A developing roller, which is arranged on the box body along the X direction;

[0009] A detection rotating member, which is arranged on the box body;

[0010] A detected member, which is used to be driven by the detection rotating member to trigger the detection component of the main component to move, triggering the detection component to swing around the swing center;

[0011] A moving device, used for moving the detected member from a first position to a second position, wherein the distance between the detected member and the swing center of the detection component when the detected member is in the first position is different from the distance between the detected member and the swing center of the detection component when the detected member is in the second position;

[0012] When the detected component is in the first position, the detected component triggers the detection component to swing at a first angular velocity;

[0013] When the detected member is in the second position, the detected member triggers the detection component to swing at a second angular velocity different from the first angular velocity.

[0014] The present invention provides a new detection method, which changes the distance between the detected object and the swing center of the detection component by a moving device, so that the detected object triggers the detection component at different positions, and the detection component is triggered at different angular velocities, thereby sending a detection signal to the main component. This detection method is simple and has good working stability.

[0015] In some embodiments, the detection rotating member has a first rotation process and a second rotation process in sequence; when the detection rotating member is in the first rotation process, the detected member performs a first trigger movement at the first position, so that the detection component swings at a first angular velocity; before the detection rotating member enters the second rotation process, the moving device moves the detected member from the first position to the second position; when the detection rotating member is in the second rotation process, the detected member performs a second trigger movement at the second position, so that the detection component swings at a second angular velocity.

[0016] In some embodiments, there is at least one first rotation process, and the first triggering movement is performed at least once; the detected member performs a return movement after triggering the detection component; the return movement of the detected member after the last first triggering movement at the first position has a different stroke compared to the previous return movement, so that the detected member moves to a position capable of triggering the moving device, and the moving device moves the detected member from the first position to the second position.

[0017] In some embodiments, the developing device further includes an annular acting member fixed relative to the box body, and the detection rotating member can act on the annular acting member when rotating, so that the detection rotating member is displaced in the X direction, thereby driving the detected member to perform a triggering movement or a return movement.

[0018] In some embodiments, the developing device further includes: a third elastic member for keeping the detecting rotating member in contact with the annular acting member.

[0019] In some embodiments, the annular action member has a first concave position, a first slope, a first protrusion position, a second concave position, a second slope, and a second protrusion position in sequence along the circumferential direction, and the first concave position, the first slope, and the first protrusion position have at least one group; the detection rotating member is provided with an action portion for contacting and interacting with the annular action member;

[0020] When the detection rotating member is in the first rotation process, the action portion moves from the first concave position along the first slope to the first protruding position, and the detection rotating member moves from the second axial position to the first axial position along the X direction, so that the detected member performs a first triggering movement at the first position;

[0021] When the action portion leaves the last first protruding position and moves to the second recessed position, the detection rotating member moves from the first axial position to the third axial position along the X direction, and the distance between the first axial position and the third axial position is different from the distance between the second axial position and the first axial position, so that the detected member moves to a position capable of triggering the moving device, and the moving device moves the detected member from the first position to the second position;

[0022] When the detection rotating member is in the second rotation process, the action portion moves from the second recessed position along the second slope to the second protruding position, and the detection rotating member moves from the third axial position to the first axial position along the X direction, so that the detected member performs a second triggering movement at the second position.

[0023] In some embodiments, a distance between the first axial position and the third axial position is greater than a distance between the second axial position and the first axial position.

[0024] In some embodiments, the annular action member further has a third recessed position and a third protruding position in sequence after the second protruding position in the axial direction;

[0025] When the detected member completes the second triggering movement, the action portion leaves the second protruding position and enters the third concave position, and the detection process is completed;

[0026] After the developing device is disassembled from the main assembly, the detection rotating member can be rotated so that the action portion moves from the third recessed position to the third protruding position, and the detected member can be moved and reset from the second position to the first position.

[0027] In some embodiments, the annular action member further has an initial fall-back slope and an initial protrusion position in sequence after the third protrusion position in the axial direction;

[0028] When the initial position of the action part is located at the initial fall-back slope, when the developing device is installed, the action part moves from the initial fall-back slope to the initial protrusion position, the detection rotating member rotates to a position capable of receiving drive, the detection rotating member moves along the X direction to a first axial position, and the detected member triggers the detection component;

[0029] The detection rotating member is driven to rotate, so that the action portion moves from the initial protruding position to the first recessed position, and the detection rotating member moves from the first axial position to the second axial position along the X direction, so that the detected member performs a return movement;

[0030] After the developing device is disassembled from the main assembly, the detected member is reset to the first position, the detecting rotating member can continue to be rotated, and the acting portion moves from the third protruding position to the initial falling slope.

[0032] In some embodiments, the second position is closer to the swing center of the detection component than the first position, so that the second angular velocity of the detection component is greater than the first angular velocity.

[0035] In some embodiments, the detected member is further provided with a reset portion that interacts with the locking portion. After the developing device is removed from the main component, when the reset portion rotates with the detected member to a position aligned with the locking portion, the detected member can move from the second position to the first position.

[0095] Embodiment 1

[0096] See also Figure 1 The image forming device of this embodiment includes a main assembly and a developing device and a drum assembly detachably mounted on a main assembly mounting chamber. In some embodiments, the drum assembly and the developing device may be detachably assembled into an integrated processing cartridge, and then the processing cartridge may be detachably mounted in the mounting chamber.

[0097] A detection component 1 is provided in the installation compartment of the main component. The detection component 1 is used to be triggered by the detection member 84 of the developing device when the developing device is installed to the main component, so that the main component can judge the model and specification of the developing device according to the situation in which the detection component 1 is triggered. The detection component 1 can be set as a detection rod, which swings around the swing center 11 after being triggered. The main component can judge the information of the developing device according to the number of times the detection component 1 is triggered and the angular velocity of the swing when triggered.

[0098] In this embodiment, a three-dimensional coordinate system is established, including mutually intersecting X direction, Y direction, and Z direction, wherein the developing device has a first end and a second end in the X direction, the first end is used to receive the driving force of the main component, the first end is in the +X direction in this embodiment, the second end is a non-driving end, the second end is in the -X direction in this embodiment, the developing roller is located at one end of the developing device in the Y direction, and the handle is located at the other end of the developing device in the Y direction. The Z direction intersects both the X direction and the Y direction. In this embodiment, the X direction is also the length direction of the developing device, the Y direction is also the width direction of the developing device, and the Z direction is also the height direction of the developing device, which may be different in other embodiments. The direction of the developing device close to the detection component 1 is the +Z direction, that is, the top, and the direction away from the detection component 1 is the -Z direction, that is, the bottom. In the developing device, the direction close to the developing roller 5 is the +Y direction, and the direction away from the developing roller 5 is the -Y direction, which may be different in other embodiments. In this embodiment, the XYZ directions are perpendicular to each other.

[0099] The developing device comprises a box body 2, a driving part 3, a transmission part 4, a developing roller 5, a first protective cover 6, a second protective cover 7 and a detection unit. The box body 2 has a first end and a second end. Figure 2 The driving part 3 is arranged at the first end of the box body 2 for receiving the power from the main assembly, the developing roller 5 is arranged on the box body 2 along the X direction, and the box body 2 is also provided with a powder bin for accommodating the developer and a stirring mechanism for stirring the developer. The first protective cover 6 is detachably fixedly arranged on the first end of the box body 2, and the second protective cover 7 is detachably fixedly arranged on the second end of the box body 2 for protecting the components on the box body 2. The inner wall of the first protective cover 6 is fixedly provided with an annular action member 61 and a mounting shaft 63 extending along the X direction.

[0100] The detection unit includes a detection rotating member 81, a transmission rod 82, a third elastic member 83, a detected member 84, a rotating shaft 85 and a moving device. The detection rotating member 81 receives power rotation from the driving part 3 through the transmission part 4, moves along the X direction through the interaction with the annular action member 61, and transmits the movement to the detected member 84 through the transmission rod 82, so that the detected member 84 triggers the detection component 1 to swing around the swing center 11.

[0101] See also Figure 2 In the present embodiment, the transmission part 4 is specifically a stirring gear, that is, a gear driving the stirring mechanism, which is arranged at the first end of the box body 2. The detection rotating member 81 is specifically a detection gear, and in other embodiments it may also be other rotating parts. The detection gear has a missing tooth portion 811. When it rotates to the missing tooth portion 811, it no longer meshes with the stirring gear, stops receiving power from the driving part 3 and stops rotating, and the detection process of the developing device is terminated. The detection rotating member 81 is arranged at the first end of the box body 2 and is rotatably mounted in the mounting shaft 63 of the first protective cover 6. The detection rotating member 81 is provided with an action portion 812 for interacting with the annular action member 61 on the +X side relative to the annular action member 61, so that the detection rotating member 81 moves along the X direction according to the concave-convex shape of the annular action member 61. In other embodiments, it is not limited to strictly move along the X direction, and at least displacement can be generated in the X direction, that is, partial displacement can be generated. In the present embodiment, the action portion 812 is based on Figure 5 , contacting the structures on the annular action member 61 in sequence in a clockwise direction.

[0102] See also Figure 1 and 2 The box body 2 is provided with a receiving groove 21 along the X direction, and a clamping portion 22 is provided in the receiving groove 21. The transmission rod 82 is movably provided on the receiving groove 21 along the X direction. The first end and the second end of the transmission rod 82 are respectively connected to the detection rotating member 81 and the detected member 84. Specifically, the first end of the transmission rod 82 abuts against the detection rotating member 81. The movement of the transmission rod 82 along the X direction is substantially synchronized with the movement of the detection rotating member 81 along the X direction. That is, when the detection rotating member 81 is displaced in the X direction, the transmission rod 82 is also displaced in the X direction. The third elastic member 83 is used to keep the action part 812 of the detection rotating member 81 in contact with the annular action member 61, that is, the third elastic member 83 makes the detection rotating member 81 tend to move in the +X direction when accumulating force. In this embodiment, the first end of the transmission rod 82 abuts against the -X side of the detection rotating member 81, and the third elastic member 83 is sleeved on the transmission rod 82, one end of which abuts against the clamping part 22 in the accommodating groove 21, and the other end abuts against the clamping block 821 on the transmission rod 82. The third elastic member 83 applies an elastic force in the +X direction to the clamping block 821, so that the first end of the transmission rod 82 remains in contact with the detection rotating member 81. The second end of the transmission rod 82 is provided with a accommodating hole 822.

[0103] See also Figure 3 The rotating shaft 85 is fixedly disposed at the second end of the box body 2 and extends along the Z direction. Figure 4The detected part 84 has a mounting hole 841, which is rotatably arranged on the rotating shaft 85 through the mounting hole 841 and can rotate in the XY plane. The first end of the detected part 84 is connected to the receiving hole 822 of the transmission rod 82, and can be lifted and lowered in the receiving hole 822 along the Z direction within a certain range. The second end of the detected part 84 is used to trigger the detection component 1 on the main component. The rotating shaft 85 is provided with a locking part 851, and the detected part 84 is provided with an unlocking part 842 that interacts with the locking part 851. In this embodiment, the locking part 851 is a protrusion arranged on the outer circumference of the rotating shaft 85, and the unlocking part 842 is a groove arranged on the inner circumference of the mounting hole 841 of the detected part 84. The moving device is a first elastic member 861, which is sleeved on the rotating shaft 85, with one end abutting against the box body 2 and the other end abutting against the detected member 84. The detected member 84 is located below the locking portion 851 and is abutted below the locking portion 851 by the first elastic member 861, thereby being locked in the first position. When the detected member 84 rotates to the position where the locking portion 851 is aligned with the unlocking portion 842, the detected member 84 is pushed upward along the Z-axis by the first elastic member 861, and the detected member 84 passes over the locking portion 851 and rises to the second position.

[0104] See also Figure 4 In this embodiment, the detected member 84 is further provided with a reset portion 843, which may be a groove on the inner wall of the mounting hole 841 of the detected member 84. When the detected member 84 is rotated to a position where the locking portion 851 is aligned with the reset portion 843, the user can reset the detected member 84 by pressing the detected member 84 downward to move it from the second position to the first position.

[0105] See also Figure 5The annular action member 61 is arranged on the inner wall of the first protective cover 6 facing the -X direction and protrudes toward the -X direction. It is provided with an initial fall-back slope 611, an initial protruding position 612, a first first fall-back position 613a, a first first recessed position 614a, a first first slope 615a, a first first protruding position 616a, a second first fall-back position 613b, a second first recessed position 614b, a second first slope 615b, a second first protruding position 616b, a second fall-back position 617, a second recessed position 618, a second slope 619, a second protruding position 620, a third recessed position 621 and a third protruding position 622 in sequence along the circumference of the annular ring in a clockwise direction, wherein the first fall-back position, the first recessed position, the first slope and the first protruding position are a group. In this embodiment, there are two adjacent groups, and the two groups are completely consistent. In other embodiments, before the second recessed position 618, the first fall-back position, the first recessed position, the first slope and the first protruding position can be set as one or more groups. The annular acting member 61 is fixed relative to the box body 2. When the detection rotating member 81 receives power to rotate, the acting part 812 interacts with the annular acting member 61. When the detection rotating member 81 rotates to different positions or sections, the acting part 812 interacts with the corresponding positions of the annular acting member 61, so that the detection rotating member 81 is pushed by the annular acting member 61 to move in the X direction.

[0106] For ease of understanding, Figure 6 The circumferential structural plane of the annular action member 61 is unfolded, and the left end and the right end in the figure are actually connected. Figure 5 Understand. In this embodiment, taking the YZ plane where the inner wall of the first protective cover 6 is located as a reference, among the adjacent protrusions and recesses, the length of the protrusion relative to the inner wall of the first protective cover 6 along the X direction is greater than that of the recess, wherein the lengths of the initial protrusion 612, the first protrusion and the second protrusion 620 along the X direction are equal. The length of the first recess relative to the inner wall of the first protective cover 6 along the X direction is greater than the length of the second recess 618 relative to the inner wall of the first protective cover 6 along the X direction (the protrusion length of the second recess 618 can be 0), so that the length L1 of the first fall-back position and the first slope along the X direction is less than the length L2 of the second fall-back position 617 and the second slope 619 along the X direction. The first slope and the second slope 619 have the same slope. The difference between the length of the third recess 621 protruding along the X direction and the length of the second protrusion 620 protruding along the X direction is L3, and L3 is less than L1 and L2. The length of the third protrusion 622 protruding along the X direction is greater than the length of the second protrusion 620 protruding along the X direction, and the difference between the two is L4. In this embodiment, the first return position is set along the X direction, that is, perpendicular to the inner wall of the first protective cover 6, so that the detected member 84 can return quickly. In other embodiments, the first return position and the second return position 617 can be inclined to the X direction, that is, set as a slope, so that the return movement of the detected member 84 has a corresponding linear velocity.

[0107] The detection rotating member 81 has a first rotation process. In this embodiment, the rotation corresponding to the action part 812 of the detection rotating member 81 in the first rotation process moves along the first slope. Before the second rotation process, the detection rotating member 81 may have one or more first rotation processes, and the number of the first rotation processes is equal to the number of the first slopes. The detection rotating member 81 has a second rotation process after the first rotation process. In this embodiment, the rotation corresponding to the action part 812 of the detection rotating member 81 in the second rotation process moves along the second slope 619.

[0108] The working process of the developing device is as follows:

[0109] Since the movement of the transmission rod 82 along the X direction is synchronized with the movement of the detection rotating member 81 along the X direction, the changes in the axial positions and the changes in the moving distances of the transmission rod 82 and the detection rotating member 81 are also the same, so in the following description, the axial positions and moving distances of the detection rotating member 81 and the transmission rod 82 are uniformly expressed without distinction. The moving positions can be referred to in Figure 7 .

[0110] The first step (installation step):

[0111] It should be noted that when the developing device is manufactured and shipped, the factory setting makes the action portion 812 located at the initial protruding position 612, and the stirring gear is directly meshed with the detection rotating member 81. Therefore, the first installation of the developing device skips this first process and starts directly from the second process. When the developing device is installed once, the detection rotating member 81 rotates one circle and finally reaches the initial falling slope 611. When the developing device is taken out of the main assembly and installed again, this first process will occur. The only difference between the initial installation and the reinstallation (the second time and thereafter) of the developing device is this point, and the following description will take the reinstallation as an example.

[0112] In the initial state before the developing device is installed again, the action portion 812 is located on the initial falling slope 611, and the detection rotating member 81 and the transmission rod 82 are located at the initial axial position A0 (see Figure 8 ), the detected member 84 is located at the first height and the first position. The action portion 812 can be located at any position of the initial falling slope 611, and the difference between the length of the initial position of the action portion 812 protruding along the X direction and the length of the second protrusion protruding along the X direction is L0.

[0113] When the developing device is installed in the main assembly again, since the action portion is located at the initial falling slope 611, the rotation angle of the detected member 84 is at a position that can trigger the detection component 1, and the second end of the detected member 84 directly triggers the detection component 1 to swing, the main assembly thus detects the installation of the developing device and outputs power to the developing device, the detection rotating member 81 rotates, so that the action portion 812 of the detection rotating member 81 moves from the initial falling slope 611 to the initial protruding position 612, and the detection rotating member 81 and the transmission rod 82 move from the initial axial position A0 along the +X direction to the first axial position A1 (see Fig. 9 , due to the small moving distance, Figure 8 The difference is not obvious), the moving distance is L0, and the detected part 84 rotates clockwise (with Figure 8-14 The slight rotation of the detection rotating member 81 causes the toothless portion 811 to rotate away from the stirring gear, and the toothed portion on the detection rotating member 81 rotates close to the stirring gear and successfully meshes with the stirring gear.

[0114] Second process (first trigger movement):

[0115] The detection rotating member 81 receives the power from the main assembly through the stirring gear and the driving part 3, the detection rotating member 81 rotates, and the action part 812 moves from the initial protruding position 612 along the first first falling position 613a to the first first recessed position 614a, so that the detection rotating member 81 and the transmission rod 82 return from the first axial position A1 to the second axial position A2 in the +X direction (see Fig.10 ), its moving distance in the X direction is equal to the length L1 of the first falling position in the X direction, the detection rotating member 81 drives the detected member 84 to rotate clockwise through the transmission rod 82, rotates back from the trigger position and stops triggering the detection component 1, at this time, the unlocking portion 842 on the detected member 84 has not rotated to the position aligned with the locking portion 851, and the detected member 84 is still locked under the locking portion 851, that is, in the first position.

[0116] The detection rotating member 81 rotates to the first rotation process, the action portion 812 moves along the first first slope 615a, and the detected member 84 is moved from the second axial position A2 to the first axial position A1 along the -X direction (see Fig. 9 ), the moving distance is the length L1 of the first slope along the X direction, and the transmission rod 82 drives the detected member 84 to rotate counterclockwise in the first position to perform the first triggering movement, and the detection component 1 is triggered and swings at the first angular velocity. The action portion 812 moves from the first first slope 615a to the first first protrusion 616a.

[0117] The third process (second first trigger movement):

[0118] This process is basically the same as the second process. The action portion 812 moves along the second first falling position 613b to the second first recessed position 614b, and the detection rotating member 81 and the transmission rod 82 return from the first axial position A1 to the second axial position A2 in the +X direction (see Fig.10 ), the moving distance is equal to the length L1 of the first falling position in the X direction, the detecting rotating member 81 drives the detected member 84 to rotate clockwise through the transmission rod 82, and rotates back from the trigger position. At this time, the unlocking portion 842 on the detected member 84 has not rotated to the position aligned with the locking portion 851, and the detected member 84 is still locked under the locking portion 851.

[0119] The detection rotating member 81 continues to rotate and enters the second first rotation process. The action portion 812 moves along the second first slope 615b, and the detection rotating member 81 and the transmission rod 82 move from the second axial position A2 to the first axial position A1 along the -X direction (see Fig. 9 ), the moving distance is the length L1 of the first slope along the X direction, the detection rotating member 81 drives the detected member 84 to rotate counterclockwise in the first position through the transmission rod 82, and performs the first triggering movement again, the detection component 1 is triggered and swings at the first angular velocity. The action portion 812 moves from the second first slope 615b to the second first protrusion 616b.

[0120] The fourth process (movement process):

[0121] The action portion 812 moves along the second falling position 617 to the second recessed position 618, and the detection rotating member 81 and the transmission rod 82 move along the +X direction from the first axial position A1 to the third axial position A3 (see Fig.11 and 12 ), the moving distance is the length L2 of the second slope 619 along the X direction, and the detection rotating member 81 drives the detected member 84 to rotate clockwise through the transmission rod 82, and rotates back from the trigger position. L2 and L1 are set to have different values. In this embodiment, L2 is set to be greater than L1. The return movement of the detection rotating member 81 and the transmission rod 82 has a larger stroke than the return movement in the second process and the third process, so that the rotation angle of the detected member 84 is larger, and the unlocking part 842 on the detected member 84 rotates to a position aligned with the locking part 851, and the detected member 84 is unlocked, and moves from the first position to the second position along the Z direction through the action of the first elastic member 861 (see Fig.13 and 14 ). The second position is closer to the swing center 11 of the detection component 1 than the first position.

[0122] Fifth process (second trigger movement):

[0123] The detection rotating member 81 continues to rotate and enters the second rotation process. The action portion 812 moves along the second slope 619, and the detection rotating member 81 and the transmission rod 82 move from the third axial position A3 to the first axial position A1 along the -X direction (see Fig.15 ), the moving distance is the length L2 of the second slope 619 along the X direction, the detection rotating member 81 drives the detected member 84 to rotate counterclockwise in the second position through the transmission rod 82, and performs the second triggering movement, and the detection component 1 is triggered and swings at the second angular velocity. Since the slopes of the first slope and the second slope 619 are equal, the detected member 84 triggers the detection component 1 at the same linear velocity, but since the position of the detected member 84 at the second position is closer to the swing center 11 of the detection component 1 than the first position, the second angular velocity at which the detection component 1 is triggered is greater than the first angular velocity. In other embodiments, the slopes of the first slope and the second slope 619 may also have a slight deviation, and the detected member 84 can trigger the detection component 1 at slightly different linear velocities, as long as the second angular velocity at which the detection component 1 is triggered is still greater than the first angular velocity. The action portion 812 moves from the second slope 619 to the second protrusion 620.

[0124] The sixth stage (test completed):

[0125] The detection rotating member 81 continues to rotate to the third concave position 621, and the detection rotating member 81 and the transmission rod 82 move from the first axial position A1 to the fourth axial position A4 along the +X direction, and the moving distance is L3, so that the toothless portion 811 of the detection rotating member 81 rotates to a position opposite to the stirring gear, so that the stirring gear and the detection rotating member 81 are disengaged, and the detection rotating member 81 no longer receives power from the driving unit 3 and stops, the detection process is completed, and the image forming device can start working. Since the third concave position 621 is in a concave state relative to the adjacent second protrusion and the third protrusion, it can prevent the detection rotating member 81 from continuing to rotate due to inertia or unexpected external force factors and accidentally meshing with the stirring gear, causing the main component to report an error and fail to print.

[0126] The seventh process (detection unit reset):

[0127] When the developing device needs to be disassembled or replaced, the developing device is taken out from the main assembly installation chamber. At this time, the action portion 812 of the detection rotating member 81 is still located at the third recessed position 621. A notch is provided on the first protective cover 6 for exposing the detection rotating member 81. The detection rotating member 81 is manually rotated through the notch so that the action portion 812 moves from the third recessed position 621 to the third protruding position 622, and the detection rotating member 81 and the transmission rod 82 move from the fourth axial position A4 to the fifth axial position A5 along the -X direction (see FIG. 5 ). Fig.16), the moving distance is L3+L4, that is, the detection rotating member 81 and the transmission rod 82 further protrude L4 in the -X direction relative to the first axial position A1 at the fifth axial position A5, so that the reset portion 843 on the detected member 84 rotates counterclockwise with the detected member 84 to a position aligned with the locking portion 851, and the detected member 84 is pressed down at this time, and moves from the second position to the first position. The detection rotating member 81 continues to rotate, so that the action portion 812 moves from the third protruding position 622 to the initial falling slope 611, and the action portion 812 returns to the initial position, and the detection rotating member 81 and the transmission rod 82 move from the fifth axial position A5 to the initial axial position A0 along the +X direction (see Figure 8 ), the moving distance is L4-L0, the reset portion 843 rotates clockwise with the detected member 84 to a position offset from the locking portion 851, and the detected member 84 is released at this time, and the first elastic member 861 abuts the detected member 84 under the locking portion 851, so that the detected member 84 is re-locked in the first position, and the detected member 84 returns to the initial position, and the detection unit completes the reset.

[0128] This embodiment provides a new detection method, which changes the distance between the detected member 84 and the swing center 11 of the detection component 1 in the Z direction by a moving device, so that the detected member 84 triggers the detection component 1 at different height positions, and the detection component 1 is triggered at different angular velocities, thereby sending a detection signal to the main component. This detection method is simple and has good working stability. Secondly, in order to correspond to more models of developing devices, the first triggering movement can be performed multiple times, and only multiple first slopes and related structures need to be set accordingly. This slope has a simple structure and is easy to manufacture, which can improve the accuracy of detection.

[0129] In some embodiments, the annular action member 61 may not be fixed relative to the box body 2, but may be set on the detection rotating member 81. The detection rotating member 81 does not move in the X direction. When the detection rotating member 81 rotates, the annular action member 61 rotates, and the transmission rod 82 contacts the annular action member 61 and moves in the X direction, thereby triggering the movement of the detected member 84.

[0130] In some embodiments, the detecting rotating member 81 and the detected member 84 may also be arranged at the same end of the box body 2 . In this case, the transmission rod 82 may be omitted, and the detected member 84 is directly driven by the detecting rotating member 81 .

[0131] In some embodiments, the movement of the detected member 84 between the first position and the second position may not be strictly along the Z direction, and may be inclined at a certain angle relative to the Z direction, as long as the distance from the swing center 11 of the detection component 1 can be changed.

[0132] In some embodiments, the first position may be at a closer distance from the swing center of the detection component than the second position, so that the first angular velocity is greater than the second angular velocity. That is, as long as the first position and the second position are at different distances from the swing center of the detection component, the first angular velocity and the second angular velocity may be different.

[0133] In some embodiments, the distance L2 between the first axial position and the third axial position may be smaller than the distance L1 between the second axial position and the first axial position. As long as L1 and L2 have different values, the configuration of the moving device can be modified as needed.

[0134] Embodiment 2

[0135] See also Figure 17-19 The main difference between this embodiment and the first embodiment is that the structure and movement mode of the detected member 84 are different.

[0136] In the present embodiment, the detected member 84 is arranged as a slider, and its motion mode is translational motion. The detected member 84 has a sliding rod 844 extending toward the +X direction. The box body 2 of the present embodiment is provided with a guide structure 9 at the second end, and the guide structure 9 is provided with a first guide portion 91 and a second guide portion 92 from bottom to top, so as to form a first track 96 between the outer surface of the box body 2 and the first guide portion 91, and the first track 96 corresponds to the first position of the detected member 84, and the end of the first track 96 close to the -Y direction is the first end, and the end close to the +Y direction is the second end. A second track 97 is formed between the first guide portion 91 and the second guide portion 92, and the second track 97 corresponds to the second position of the detected member 84, and the end of the second track 97 close to the -Y direction is the first end, and the end close to the +Y direction is the second end. The detected member 84 slides in the first track 96 and the second track 97 through the sliding rod 844.

[0137] In the present embodiment, the first track 96 and the second track 97 are arranged along the Y direction, and the detected member 84 moves along the Y direction in the first track 96 and the second track 97, and the detected member 84 can trigger the detection component 1 of the main component through its side 845 facing +Y. In other embodiments, the first track 96 and the second track 97 can be arranged along an angle inclined with the Y direction on the XY plane, and the detected member 84 can also move along an angle inclined with the Y direction on the XY plane. In some embodiments, the first track 96 and the second track 97 can even be arranged along an angle inclined with the XY plane, and the detected member 84 can also move along an angle inclined with the XY plane, as long as the detected member 84 can move in a translational manner to trigger the detection component 1. The first track 96 and the second track 97 can also extend in the Z direction, so that the detected member 84 can move in the Z direction along the first track 96 and the second track 97 and touch the detection component 1.

[0138] The moving device is arranged outside the first end of the first track 96 , and includes a second elastic member 862 and a push bead 863 arranged on the second elastic member 862 . The push bead 863 facilitates pushing the detected member 84 .

[0139] The detection unit also includes a flexible member 88, which is respectively connected to the transmission rod 82 and the detected member 84. The box body 2 is also provided with a guide mechanism 23 for guiding the movement of the flexible member 88. The guide mechanism 23 is in an arc shape and is arranged at the bend of the flexible member 88, thereby limiting the deformation and movement direction of the flexible member 88, so that the flexible member 88 can turn the power of the transmission rod 82 along the X direction by 90 degrees and transfer it to the detected member 84, so that the detected member 84 can move along the Y direction. In addition, the flexible member 88 can also adapt to the different heights of the detected member 84, and can transfer power to the detected member 84 in the first position and the second position. The flexible member 88 can be made of a plurality of strands of steel wire.

[0140] The setting of the flexible member can still transmit the power of the transmission rod to the detected member when the moving direction of the transmission rod and the moving direction of the detected member are different. In other embodiments, the transmission rod is displaced in the X direction and the detected member is displaced in the Y direction, or the transmission rod is displaced in the X direction and the detected member is displaced in the Z direction.

[0141] The arrangement of the developing device at the first end of this embodiment is substantially the same as that of the first embodiment, and will not be described in detail.

[0142] The working process of the developing device is as follows:

[0143] In this embodiment, the moving distance of the detected member 84 along the Y direction is equal to the moving distance of the detecting rotating member 81 and the transmission rod 82 along the X direction, which will not be described in detail below.

[0144] The first step (installation step):

[0145] In the initial state before the developing device is installed again, the action portion 812 is located on the initial falling slope 611, the detection rotating member 81 and the transmission rod 82 are located at the initial axial position A0, and the detected member 84 is located on the first track 96 (see Fig.19). The action portion 812 can be located at any position of the initial return slope 611, and the difference between the length of the initial position of the action portion 812 along the X direction and the length of the second protrusion along the X direction is L0. When the developing device is installed in the main component again, since the action portion is located at the initial return slope 611, the rotation angle of the detected member 84 is at a position that can trigger the detection component 1, and the second end of the detected member 84 directly triggers the detection component 1 to swing, and the main component thereby detects the installation of the developing device and outputs power to the developing device, and the detection rotating member 81 rotates, so that the action portion 812 of the detection rotating member 81 moves from the initial return slope 611 to the initial protruding position 612, and the detection rotating member 81 and the transmission rod 82 move from the initial axial position A0 along the +X direction to the first axial position A1, and the moving distance is L0. This slight rotation of the detection rotating member 81 causes its toothless portion 811 to rotate away from the stirring gear, and the toothed portion on the detection rotating member 81 rotates close to the stirring gear and successfully meshes with it.

[0146] Second process (first trigger movement):

[0147] The detection rotating member 81 receives the power from the main assembly through the stirring gear and the driving part 3, and the detection rotating member 81 rotates, and the action part 812 moves from the initial protruding position 612 along the first first falling position 613a to the first first recessed position 614a, so that the detection rotating member 81 and the transmission rod 82 return from the first axial position A1 to the second axial position A2 in the +X direction, and the moving distance is equal to the length L1 of the first falling position in the X direction, and the detected member 84 moves along the -Y direction to the first end of the first track 96 (see Fig. 20 ), but the sliding rod 844 does not reach the position of the top ball 863.

[0148] The detecting rotating member 81 rotates to the first rotation process, the acting portion 812 moves along the first first slope 615a, and the detected member 84 is moved from the second axial position A2 to the first axial position A1 along the -X direction, and the moving distance is the length L1 of the first slope along the X direction. The detected member 84 moves along the +Y direction to the second end of the first track 96 (see Fig.21 ), a first triggering movement is performed, the detection component 1 is triggered and swings at a first angular velocity. The action portion 812 moves from the first first slope 615a to the first first protrusion 616a.

[0149] The third process (second first trigger movement):

[0150] This process is basically the same as the second process. The action portion 812 moves along the second first return position 613b to the second first recessed position 614b. The detection rotating member 81 and the transmission rod 82 return from the first axial position A1 to the second axial position A2 in the +X direction. The moving distance is equal to the length L1 of the first return position in the X direction. The detected member 84 moves along the -Y direction to the first end of the first track 96 (see FIG. 1 ). Fig. 20 ), but the sliding rod 844 does not reach the position of the top ball 863.

[0151] The detection rotating member 81 continues to rotate and enters the second first rotation process. The action portion 812 moves along the second first slope 615b. The detection rotating member 81 and the transmission rod 82 are moved from the second axial position A2 to the first axial position A1 along the -X direction. The moving distance is the length L1 of the first slope along the X direction. The detected member 84 moves along the +Y direction to the second end of the first track 96 (see Fig.21 ), the first triggering movement is performed again, the detection component 1 is triggered and swings at the first angular velocity. The action portion 812 moves from the second first slope 615b to the second first protrusion 616b.

[0152] The fourth process (movement process):

[0153] The action portion 812 moves along the second fall-back position 617 to the second recessed position 618, the detection rotating member 81 and the transmission rod 82 move from the first axial position A1 to the third axial position A3 along the +X direction, and the moving distance is the length L2 of the second slope 619 along the X direction, and the detected member 84 moves along the -Y direction to the first end of the first track 96. L2 and L1 are set to have different values. In this embodiment, L2 is set to be greater than L1. The return movement of the detection rotating member 81 and the transmission rod 82 has a larger stroke than the return movement in the second process and the third process, so that the movement distance of the detected member 84 is larger. The detected member 84 moves to the outside of the first end of the first track 96, and the sliding rod 844 is located above the top bead 863. It moves from the first position to the second position along the Z direction through the action of the second elastic member 862 (see Fig. 22 ), namely, at the second track 97. The second position is closer to the swing center 11 of the detection component 1 than the first position.

[0154] Fifth process (second trigger movement):

[0155] The detection rotating member 81 continues to rotate and enters the second rotation process. The action portion 812 moves along the second slope 619. The detection rotating member 81 and the transmission rod 82 move from the third axial position A3 to the first axial position A1 along the -X direction. The moving distance is the length L2 of the second slope 619 along the X direction. The detected member 84 enters the second track 97 along the +Y direction and moves to the second end of the second track 97 (see Fig.23 ), the second triggering motion is performed, and the detection component 1 is triggered and swings at a second angular velocity. Since the slopes of the first slope and the second slope 619 are equal, the detected member 84 triggers the detection component 1 at the same linear motion speed, but since the position of the detected member 84 at the second position is closer to the swing center 11 of the detection component 1 than the first position, the second angular velocity at which the detection component 1 is triggered is greater than the first angular velocity. The action portion 812 moves from the second slope 619 to the second protrusion 620.

[0156] The sixth stage (test completed):

[0157] The detection rotating member 81 continues to rotate to the third concave position 621, and the detection rotating member 81 and the transmission rod 82 move from the first axial position A1 to the fourth axial position A4 along the +X direction, and the moving distance is L3, so that the toothless portion 811 of the detection rotating member 81 rotates to a position opposite to the stirring gear, so that the stirring gear and the detection rotating member 81 are disengaged, and the detection rotating member 81 no longer receives power from the driving unit 3 and stops, the detection process is completed, and the image forming device can start working. Since the third concave position 621 is in a concave state relative to the adjacent second protrusion and the third protrusion, it can prevent the detection rotating member 81 from continuing to rotate due to inertia or unexpected external force factors and accidentally meshing with the stirring gear, causing the main component to report an error and fail to print.

[0158] The seventh process (detection unit reset):

[0159] When the developing device needs to be disassembled or replaced, the developing device is taken out from the main assembly installation chamber. At this time, the action portion 812 of the detection rotating member 81 is still located at the third recessed position 621. The first protective cover 6 is provided with a notch for exposing the detection rotating member 81. The detection rotating member 81 is manually rotated through the notch so that the action portion 812 moves from the third recessed position 621 to the third protruding position 622. The detection rotating member 81 and the transmission rod 82 move from the fourth axial position A4 along the -X direction to the fifth axial position A5. The moving distance is L3+L4, that is, the detection rotating member 81 and the transmission rod 82 at the fifth axial position A5 further protrude L4 along the -X direction relative to the first axial position A1, so that the detected member 84 moves along the +Y direction to the outside of the second end of the second track 97, and the sliding rod 844 of the detected member 84 extends out of the edge of the second end of the first guide portion 91 (see FIG. 1 ). Fig.24), at this time, the detected member 84 is pressed down and moves from the second position to the first position. The detection rotating member 81 continues to rotate, so that the action portion 812 moves from the third protruding position 622 to the initial falling slope 611, and the action portion 812 returns to the initial position. The detection rotating member 81 and the transmission rod 82 move from the fifth axial position A5 along the +X direction to the initial axial position A0, and the moving distance is L4-L0. The detected member 84 enters the second end of the first track 96 along the -Y direction and returns to the initial position, and the detection unit completes the reset.

[0160] Embodiment 3

[0161] See also Figure 25-28 The main difference between this embodiment and the second embodiment is that the movement direction of the detected member 84 is different.

[0162] See also Fig.26 In this embodiment, a guide structure 9 is provided inside the second protective cover 7, and the guide structure 9 is provided with a third guide portion 93, a fourth guide portion 94 and a fifth guide portion 95 from bottom to top. A first track 96 is formed between the third guide portion 93 and the fourth guide portion 94, and the first track 96 corresponds to the first position of the detected member 84. The end of the first track 96 close to the +X direction is the first end, and the end close to the -X direction is the second end. A second track 97 is formed between the fourth guide portion 94 and the fifth guide portion 95, and the second track 97 corresponds to the second position of the detected member 84. The end of the second track 97 close to the +X direction is the first end, and the end close to the -X direction is the second end. See. Fig. 27 The detected member 84 has a sliding rod 844 extending toward the −Y direction and tilted toward the +X direction. The detected member 84 slides in the first track 96 and the second track 97 through the sliding rod 844 .

[0163] In this embodiment, the first track 96 and the second track 97 are arranged along the X direction, and the detected member 84 moves along the X direction in the first track 96 and the second track 97, and the detected member 84 can trigger the detection component 1 of the main component through its inclined side 845 toward the +Y direction. In other embodiments, the first track 96 and the second track 97 can be arranged at an angle inclined to the X direction on the XY plane, and the detected member 84 can also move at an angle inclined to the X direction on the XY plane. In some embodiments, the first track 96 and the second track 97 can even be arranged at an angle inclined to the XY plane, and the detected member 84 can also move at an angle inclined to the XY plane, as long as the detected member 84 can move in a translational manner to trigger the detection component 1.

[0164] The moving device is arranged outside the first end of the first track 96, and is specifically implemented as a first moving inclined surface 864 arranged on the side of the third guide portion 93 located in the +X direction. In other embodiments, the moving device of this embodiment may also adopt the second elastic member 862 and the top ball 863 structure of the second embodiment, and the moving device of the second embodiment may also adopt the first moving inclined surface 864 of this embodiment. The detection unit of this embodiment also includes a descending device, which is arranged outside the second end of the second track 97, and is specifically implemented as a second moving inclined surface 87 arranged on the side of the fourth guide portion 94 located in the -X direction. When the detected part 84 moves to the bottom of the second moving inclined surface 87, it will be pushed to descend by itself, without the need for the user to press down the detected part 84 by hand. In other embodiments, the descending device may not be used, but the user may manually press down the detected part 84, and the second embodiment may also be provided with a descending device, without the need for the user to manually press down the detected part 84.

[0165] The detection unit further includes a flexible member 88, which is respectively connected to the transmission rod 82 and the detected member 84. The box body 2 is also provided with a guide mechanism 23 for guiding the movement of the flexible member 88. The flexible member 88 can adapt to different heights of the detected member 84 and can transmit power to the detected member 84 in both the first position and the second position. The flexible member 88 can be made of a plurality of strands of steel wire twisted together.

[0166] The arrangement of the developing device at the first end of this embodiment is substantially the same as that of the first embodiment, and will not be described in detail.

[0167] The working process of the developing device is as follows:

[0168] In this embodiment, the moving distance of the detected member 84 along the X direction is equal to the moving distance of the detecting rotating member 81 and the transmission rod 82 along the X direction, which will not be described in detail below.

[0169] The first step (installation step):

[0170] In the initial state before the developing device is installed again, the action portion 812 is located on the initial falling slope 611, the detection rotating member 81 and the transmission rod 82 are located at the initial axial position A0, and the detected member 84 is located on the first track 96 (see Fig.25). The action portion 812 can be located at any position of the initial return slope 611, and the difference between the length of the initial position of the action portion 812 along the X direction and the length of the second protrusion along the X direction is L0. When the developing device is installed in the main component again, since the action portion is located at the initial return slope 611, the rotation angle of the detected member 84 is at a position that can trigger the detection component 1, and the second end of the detected member 84 directly triggers the detection component 1 to swing, and the main component thereby detects the installation of the developing device and outputs power to the developing device, and the detection rotating member 81 rotates, so that the action portion 812 of the detection rotating member 81 moves from the initial return slope 611 to the initial protruding position 612, and the detection rotating member 81 and the transmission rod 82 move from the initial axial position A0 along the +X direction to the first axial position A1, and the moving distance is L0. This slight rotation of the detection rotating member 81 causes its toothless portion 811 to rotate away from the stirring gear, and the toothed portion on the detection rotating member 81 rotates close to the stirring gear and successfully meshes with it.

[0171] Second process (first trigger movement):

[0172] The detection rotating member 81 receives the power from the main assembly through the stirring gear and the driving part 3, and the detection rotating member 81 rotates, and the action part 812 moves from the initial protruding position 612 along the first first falling position 613a to the first first recessed position 614a, so that the detection rotating member 81 and the transmission rod 82 return from the first axial position A1 to the second axial position A2 in the +X direction, and the moving distance is equal to the length L1 of the first falling position in the X direction, and the detected member 84 moves along the +X direction to the first end of the first track 96 (see Fig.28 ), but the sliding rod 844 does not reach the position of the first moving inclined surface 864.

[0173] The detection rotating member 81 rotates to the first rotation process, the action part 812 moves along the first first slope 615a, and the detected member 84 is moved from the second axial position A2 to the first axial position A1 along the -X direction, and the moving distance is the length L1 of the first slope along the X direction. The detected member 84 moves along the -X direction to the second end of the first track 96 to perform the first triggering movement, and the detection component 1 is triggered and swings at the first angular velocity. The action part 812 moves from the first first slope 615a to the first first protrusion 616a.

[0174] The third process (second first trigger movement):

[0175] This process is basically the same as the second process. The action portion 812 moves along the second first return position 613b to the second first recessed position 614b. The detection rotating member 81 and the transmission rod 82 return from the first axial position A1 toward the +X direction to the second axial position A2. The moving distance is equal to the length L1 of the first return position in the X direction. The detected member 84 moves along the +X direction to the first end of the first track 96, but the sliding rod 844 does not reach the position of the first moving inclined surface 864.

[0176] The detection rotating member 81 continues to rotate and enters the second first rotation process. The action part 812 moves along the second first slope 615b. The detection rotating member 81 and the transmission rod 82 are moved from the second axial position A2 to the first axial position A1 along the -X direction. The moving distance is the length L1 of the first slope along the X direction. The detected member 84 moves along the -X direction to the second end of the first track 96 and performs the first triggering movement again. The detection component 1 is triggered and swings at the first angular velocity. The action part 812 moves from the second first slope 615b to the second first protrusion 616b.

[0177] The fourth process (movement process):

[0178] The action portion 812 moves along the second return position 617 to the second recessed position 618, and the detection rotating member 81 and the transmission rod 82 move from the first axial position A1 to the third axial position A3 along the +X direction, and the moving distance is the length L2 of the second slope 619 along the X direction, and the detected member 84 moves along the +X direction to the first end of the first track 96. L2 and L1 are set to have different values. In this embodiment, L2 is set to be greater than L1. The return movement of the detection rotating member 81 and the transmission rod 82 has a larger stroke than the return movement in the second process and the third process, so that the movement distance of the detected member 84 is larger. The detected member 84 moves to the outside of the first end of the first track 96, and the sliding rod 844 is located above the first moving inclined surface 864. It moves from the first position to the second position along the Z direction through the action of the first moving inclined surface 864 (see Fig.29 ), namely, at the second track 97. The second position is closer to the swing center 11 of the detection component 1 than the first position.

[0179] Fifth process (second trigger movement):

[0180] The detection rotating member 81 continues to rotate and enters the second rotation process. The action part 812 moves along the second slope 619. The detection rotating member 81 and the transmission rod 82 move from the third axial position A3 to the first axial position A1 along the -X direction. The moving distance is the length L2 of the second slope 619 along the X direction. The detected member 84 enters the second track 97 along the -X direction and moves to the second end of the second track 97 to perform the second triggering movement. The detection component 1 is triggered and swings at the second angular velocity. Since the slopes of the first slope and the second slope 619 are equal, the detected member 84 triggers the detection component 1 at the same linear motion speed. However, since the position of the detected member 84 at the second position is closer to the swing center 11 of the detection component 1 than the first position, the second angular velocity at which the detection component 1 is triggered is greater than the first angular velocity. The action part 812 moves from the second slope 619 to the second protrusion 620.

[0181] The sixth stage (test completed):

[0182] The detection rotating member 81 continues to rotate to the third concave position 621, and the detection rotating member 81 and the transmission rod 82 move from the first axial position A1 to the fourth axial position A4 along the +X direction, and the moving distance is L3, so that the toothless portion 811 of the detection rotating member 81 rotates to a position opposite to the stirring gear, so that the stirring gear and the detection rotating member 81 are disengaged, and the detection rotating member 81 no longer receives power from the driving unit 3 and stops, the detection process is completed, and the image forming device can start working. Since the third concave position 621 is in a concave state relative to the adjacent second protrusion and the third protrusion, it can prevent the detection rotating member 81 from continuing to rotate due to inertia or unexpected external force factors and accidentally meshing with the stirring gear, causing the main component to report an error and fail to print.

[0183] The seventh process (detection unit reset):

[0184] When the developing device needs to be disassembled or replaced, the developing device is taken out from the main assembly installation chamber. At this time, the action portion 812 of the detection rotating member 81 is still located at the third recessed position 621. The first protective cover 6 is provided with a notch for exposing the detection rotating member 81. The detection rotating member 81 is manually rotated through the notch so that the action portion 812 moves from the third recessed position 621 to the third protruding position 622. The detection rotating member 81 and the transmission rod 82 move from the fourth axial position A4 to the fifth axial position A5 along the -X direction. The moving distance is L3+L4, that is, the detection rotating member 81 and the transmission rod 82 at the fifth axial position A5 further protrude L4 along the -X direction relative to the first axial position A1, so that the detected member 84 moves along the -X direction to the outside of the second end of the second track 97. At this time, the sliding rod 844 of the detected member 84 is located below the second moving inclined surface 87 (see FIG. 1 ). Fig.30), and is pressed down by the second moving inclined surface 87 and moves from the second position to the first position. The detection rotating member 81 continues to rotate, so that the action portion 812 moves from the third protruding position 622 to the initial falling slope 611, and the action portion 812 returns to the initial position. The detection rotating member 81 and the transmission rod 82 move from the fifth axial position A5 along the +X direction to the initial axial position A0, and the moving distance is L4-L0. The detected member 84 enters the second end of the first track 96 along the +X direction and returns to the initial position, and the detection unit completes the reset.
