Problems solved by technology

However, due to the combined error caused by the aging of the torsion spring and the resistance of the toner, the time value for the light transmission window on the code wheel to pass through the code detection unit has uncertainty and changes within the error range, which will affect the image processing box. Accuracy of state identifying information

Abstract

The invention relates to an image processing box in an electronic photographic imager. The image processing box comprises a development unit and a photosensitive drum box, wherein the photosensitive drum box is detachably assembled with the development unit; the image processing box further comprises a coding device for transmitting state identification information to the electronic photographic imager, which the coding device consists of a plane mechanism; and linear reciprocating motion of a signal shading sheet in the coding device is realized by the rotating action of a driving gear. By adopting the technical scheme, the plane mechanism device is adopted in the coding device, and the motion loci of the composition members of the plane mechanism device have high accuracy, so that the detection time that the non-transparent shading sheet passing through a code reader in the set time is more accurate; and compared with a coding wheel device driven by a torsion spring coupling device,the image processing box can be accurately identified all the time and effectively operated is ensured more accurately and effectively.

Description

technical field [0001] The present invention relates to an image processing cartridge in an electrophotographic imager. Background technique [0002] The electrophotographic imager converts text and graphic information to generate a laser beam, and then scans the photosensitive drum along the axis of the photosensitive drum at a constant speed through a series of optical systems, thereby forming an electrostatic latent image corresponding to the input information on the photosensitive drum. After a series of actions, it is transferred to the electrostatic latent image part to form a visible image, and the visible image of the developer formed on the photosensitive drum is finally transferred and fixed on the recording medium. [0003] After many uses, electrophotographic imagers require various maintenance work, such as replacing the photosensitive drum, replenishing the developer, adjusting the charging element, cleaning the waste toner container, and so on. Therefore, ele...
