Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
Applicants' studies found that:
In order to detect whether the developer storage amount in the developing box is exhausted or not, a processing box exists in the prior art, a transparent window is formed in the developing box, light rays are emitted into the box from the transparent window, and when the developer is sufficient, the light rays are blocked by the developer; when the residual quantity of the developer is insufficient, the light is reflected out after passing through the inner space of the developing box, and the electrophotographic image forming apparatus receives the change of the light signal to send out corresponding prompt information.
However, in the above technology, the inner wall of the transparent window is easy to be adhered with residual carbon powder, which affects the penetration of light, even if the developer in the developing box is exhausted, the carbon powder remained on the inner wall of the transparent window still affects the penetration of the light path, thereby affecting the detection accuracy.
In view of this, in the present disclosure, referring to fig. 1 to 11, there is provided a process cartridge including a developing cartridge 100, a light sensing portion 200, and a movable portion;
the developing hopper 100 is for storing developer;
The light sensing part 200 is connected to the outer wall surface of the developing bin 100, a light passage 201 is arranged in the light sensing part 200, a relief channel 202 is arranged on the upper side and/or the lower side of the light passage 201, the light passage 201 and the relief channel 202 form a through accommodating chamber 203, and it is noted that the accommodating chamber 203 can be a chamber inside the light sensing part 200, so that the inner parts of the light sensing part can be protected relatively clean, or an open chamber directly communicated with the outside can be formed, namely, the relief channel 202 can be arranged in the structural wall surface of the light sensing part 200, can also extend out of the structural wall surface of the light sensing part 200 and be communicated with the outside, and thus, the light sensing part can be convenient for manual adjustment interference;
The movable part comprises a shielding member 310 and a moving member 320, the moving member 320 is arranged in the developing bin 100, the shielding member 310 is connected with the moving member 320, the shielding member 310 is arranged in the accommodating chamber 203 and is switched between the light path 201 and the yielding channel 202 under the driving of the moving member 320, the moving member 320 is provided with a contact plane 321, and the contact plane 321 is abutted with the developer.
It should be noted that, the light sensing portion 200 is fixed on the developing chamber 100, the movable portion is used to control the on-off of the light path 201 in the light sensing portion 200, and the movable portion senses the storage of the developer in the developing chamber 100, more specifically, the movable portion includes a shielding member 310 and a moving member 320, wherein the shielding member 310 is slidable in the accommodating chamber 203, and the moving member 320 applies a force to the shielding member 310.
Since the light path 201 in the light sensing portion 200 is located outside the developing bin 100, the shielding member 310 can be switched between the light path 201 and the yielding channel 202 in the accommodating chamber 203, the position of the shielding member 310 is related to the position of the moving member 320, the contact plane 321 of the moving member 320 is adapted to the storage amount of the developer, when the storage amount of the developer is sufficient and is supported by the developer, the contact plane 321 is correspondingly located at a high position, and the moving member 320 drives the shielding member 310 to shield the light path 201; when the remaining amount of the developer is insufficient, the supporting point of the developer is also lowered, the contact plane 321 is correspondingly at a low position, and the moving member 320 drives the shielding member 310 to leave the optical path 201 and enter the abdication channel 202, so as to form a change of an optical signal.
It should be noted that for the specific mechanical environment in which the moving member 320 drives the shutter member 310, there are at least two embodiments:
Embodiment 1: the moving member 320 applies a force to the shielding member 310 only by gravity, so that the shielding member 310 can move between the light path 201 and the yielding channel 202, when the remaining amount of the developer is insufficient and the highest plane of the developer correspondingly descends, the moving member 320 correspondingly descends due to the gravity, so that the contact plane 321 of the moving member 320 is still abutted against the highest plane of the developer to feed back the actual developer stock, and naturally, if the developer is exhausted, the contact plane 321 of the moving member 320 cannot be naturally contacted with the developer, or a small part of the developer still remains, and the contact plane 321 of the moving member 320 still contacts the part of the developer, but correspondingly the shielding member 310 is moved into the yielding channel 202;
Embodiment 2: in this embodiment, the driving unit may further include a force-receiving component, that is, there is another force-applying portion to apply force to the moving component 320, so that the moving component 320 moves according to a set state, in order to make the moving component 320 better adapt to the storage of the developer, and avoid that the contact plane 321 is buried under the highest plane of the developer and cannot well reflect the real developer storage, so that the driving unit drives the moving component 320 to move, where the movement may be a movement in a vertical direction, or may be a rotation about a connection axis, so that the moving component 320 can better separate from the developer, and then the moving component 320 contacts the top surface of the developer again under the action of its own gravity or other auxiliary force-receiving components, so as to improve the detection accuracy.
Additionally, when the driving unit drives the moving member 320 to move, the yielding channel 202 is disposed on both the upper side and the lower side of the optical path 201, one side is used for yielding movement when the driving unit drives, and the other side is used for yielding movement caused by natural descent of the moving member 320. When only the moving member 320 is under the gravity, only one side of the yielding channel 202 is provided, because the displacement trend of the moving member 320 is unidirectional.
For the implementation of the drive unit, there are at least the following two examples:
Example 1:

In one embodiment, the elastic action part 402 is made of POM material, has good elasticity, does not adversely affect the developer, and has good stability.

Additionally, the connection between the moving member 320 and the shielding member 310 may be a direct physical connection or may be no physical connection, so long as there is a strong transmission between them, so long as the moving member 320 is convenient to control the shielding member 310 to move, so at least the following three embodiments exist for the connection manner between the moving member 320 and the shielding member 310:
