Processing box

Abstract

The invention discloses a processing box which includes: at least a sensitometric drum, a developing roller, a protective case for containing the sensitometric drum and the developing roller, the sensitometric drum is installed on the protective case for forming an electrostatic latent image, the developing roller makes the electrostatic latent image on the sensitometric drum developing; and a handle that can be flexible installed on the protective case and has an extending state and a shrinking state corresponding to the extending state. Compared with the prior art, the processing box has advantages that the handle in shrinking state can reduce packaging and storing space, save cost; the handle in extending state is convenient for user dismounting the processing box into the electronic imager; has more stable and reliable structure than the folding handle.

Description

technical field [0001] The present invention relates to a process cartridge for an electronic image forming apparatus such as a laser printer, copier or facsimile machine. Background technique [0002] In the prior art, a process cartridge of a common electronic imaging device includes: a photosensitive drum, a developing roller, and a protective case for accommodating the photosensitive drum and the developing roller. The photosensitive drum is used to receive the electrostatic latent image; the developer roller supplies developer to the photosensitive drum to develop the electrostatic latent image. [0003] When the developer in the process cartridge runs out, the process cartridge needs to be replaced. For this purpose, a conventional process cartridge is provided with a handle on its protective case for easy handling of the process cartridge. [0004] However, the handle of the above-mentioned process cartridge protrudes farther than the outer periphery of the process ...

AI Technical Summary

Problems solved by technology

[0004] However, the handle of the above-mentioned process cartridge protrudes farther than the outer periphery of the process cartridge protective case, increasing the size of the process cartridge, which is uneconomical.

[0005] Another kind of process box is also provided in the prior art, and the process box has a foldable handle, and the handle is pivotally mounted on the process box protective shell, which can achieve the purpose of saving space, but when it is installed and disassembled Easy to rotate around a pivot axis and therefore unstable
