[ technical field ] A method for producing a semiconductor device

The invention belongs to the field of electronic imaging, and relates to a power receiving part, in particular to a processing box comprising the power receiving part.

[ background of the invention ]

Process cartridges are widely used as replaceable consumables in electronic image forming apparatuses such as printers, copiers, and the like. The electronic imaging device mainly works in the following processes in the imaging process: the charging assembly charges the photosensitive member surface with a uniform predetermined charge; forming an electrostatic latent image on the surface of the photosensitive member having a predetermined charge after exposure treatment; the developing component sends the developer to the photosensitive component to develop the electrostatic latent image on the surface of the photosensitive component; after the transfer, the developer on the electrostatic latent image is transferred to an image recording medium such as a paper sheet; the cleaning assembly cleans the incompletely transferred developer on the photosensitive member surface to let the photosensitive member enter the next charging, i.e., the next cycle process.

During this cycle, the process cartridge portion includes at least a charging member for charging the photosensitive member, and a developing member for supplying the photosensitive member with the developer. In the prior art, the photosensitive member is a photosensitive drum, and the developing member is a developing roller. The process cartridge itself does not contain a driving force generating part such as a motor, but receives a rotational driving force from the electronic image forming apparatus on which it is located. Because the processing box is a replaceable consumable used on the electronic imaging device, the processing box can be replaced independently for ensuring that a common user can easily, and the power receiving part arranged on the processing box and the rotary driving force transmission part arranged on the electronic imaging device can be coupled when transmitting the rotary driving force when receiving the rotary driving force and can be separated when not transmitting the rotary driving force.

Generally, in a process cartridge, a photosensitive member photosensitive drum for generating an electrostatic latent image of a developer, a developing member developing roller for supplying the developer to the photosensitive member, an agitating frame for agitating the developer, an agitating frame for supplying the developer to the developing member, and a charging member charging roller for charging the photosensitive member in some types of process cartridges are rotatable like a roller-like structure and are therefore collectively called a rotating roller. The power receiving part can be arranged on any rotating roller and transmits the rotating driving force to other rotating rollers through a gear set, or directly drives the gear set to drive each rotating roller.

In the prior art, the developer, the developing roller and the like are disposed in the powder hopper, and the photosensitive drum and the collected printing waste powder are disposed in the waste powder hopper. Of course, there are some waste powder bins in which the waste powder collecting portion is not provided in the process cartridge. Usually, the powder bin and the waste powder bin are connected into a whole to be installed in the electronic imaging device, but some models are designed to be split, namely, the powder bin and the waste powder bin are installed in the electronic imaging device separately. The present invention is only exemplified by an integral structure.

For a color processing box, because all color processing boxes are not needed to participate in partial color imaging, in order to prevent the developing part and the photosensitive part from being pressed to damage and affect imaging due to long-time mutual contact, or prevent the developing part and the photosensitive part from being damaged due to mutual friction, a method of separating a roller and a drum is adopted in the prior art when the color processing box does not work, as shown in fig. 2, namely, a powder bin containing a developing component and a developer and a waste powder bin containing the photosensitive part and the collected waste developer are subjected to relative movement, so that the developing component is not contacted with the photosensitive component any more. In the invention, the powder bin is only used for driving the developing component to move, of course, the waste powder bin can be used for driving the photosensitive component to move relative to the developing component, and the principle is the same, so that the detailed description is omitted.

When the powder bin and the developing element move, if a fixed power receiving part is arranged on the powder bin, when the power receiving part is loosely connected with the electronic imaging device, although the power receiving part is easy to disengage, the power receiving part is difficult to re-engage when the powder bin moves back to continue working; when the power receiving member and the electrophotographic apparatus are tightly connected, it is liable to cause the disengagement failure to prevent the separation operation of the roller drum. It is therefore necessary to provide a power receiving member that remains engaged with the electrophotographic image forming apparatus throughout the separation of the roller drums. It is difficult to ensure engagement when the process cartridge is first loaded if a cross-coupling or the like is simply used, so that the power receiving part and the electronic image forming apparatus cannot be engaged at all times.
