Embodiment 2

[0078] Wherein, in the existing process cartridge, the developing cartridge slides along the slideway on the drum cartridge for a long distance so that the developing roller 28 and the photosensitive drum 16 can be in place. 10 falls off, and an elastic locking device and a forcing device are often provided at the rear of the drum box 10, which makes the structure of the drum box complicated, and the drum box 10 is subject to more elastic forces, making the structure of the drum box 10 becomes unstable, for this reason, this embodiment provides a kind of processing box, specifically can refer to Figure 1-11 As shown, the process box includes a detachable developer cartridge 20 and a drum cartridge 10, wherein the end of the drum cartridge 10 is provided with a mounting portion 12; Telescopic telescopic assembly 23, telescopic assembly 23 is used for snapping into installation portion 12 when drum cartridge 10 and developing cartridge 20 are installed, so that drum cartridge 1...

Embodiment 3

[0083] This embodiment provides a developing cartridge 20, such as Figure 2-8 As shown, the developer cartridge 20 is detachably connected with the drum cartridge 10, wherein, the end of the developer cartridge 20 is provided with an end cover 21 and a telescopic assembly 23 that stretches towards the end cover 21, and the end of the drum cartridge 10 is provided with a mounting portion 12. The telescopic assembly 23 is used to snap into the installation part 12 when the drum cartridge 10 and the developer cartridge 20 are installed, so that the drum cartridge 10 and the developer cartridge 20 are detachably connected, so that the developer cartridge 20 and the drum cartridge 10 are connected by telescopic The component 23 snaps into the installation part 12 to prevent the developer cartridge 20 from falling off the drum cartridge 10, avoiding the problem that the drum cartridge 10 is provided with an elastic locking device and a forcing device, which causes the drum cartridge...

Abstract

The invention relates to a developer cartridge, a process cartridge and an electronic imaging device. The process cartridge comprises: a developer cartridge and a drum cartridge which can be disassembled from each other. The first protruding part and the second protruding part, wherein, the two end faces of the drum cartridge are also provided with mounting parts for detachably installing the developing cartridge, and the two ends of the developing cartridge are respectively provided with There is an end cover, and an accommodating part for accommodating the first protruding part, the mounting part and the second protruding part is provided on the end cap; the first protruding part and the second protruding part The end face extends beyond the outer surface of the end cap. The processing box provided by the invention solves the technical problems of the overall length of the processing box and the complex and unstable structure of the drum box due to the need to reserve space for the protrusion and the slideway in the existing processing drum box.

Description

technical field [0001] The invention relates to a printing device, in particular to a developing box, a processing box and an electronic imaging device. Background technique [0002] An electronic imaging device is a device that forms an image on a recording material through electrophotographic imaging processing technology, such as: electrophotographic copying, laser printers, electrophotographic printers, fax machines, word processors, etc., where the electronic imaging device mainly includes Assemble the main frame and the process box of the components needed to form the image. There is a space for installing the process box inside the main frame. The process box is detachably installed in the electronic imaging device. When printing, the photosensitive element in the process box can be The image information is converted into an electronic latent image, and then the electronic latent image is converted into a solid toner image, and the toner image is transferred to the pr...
