Embodiment Construction
[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0038] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

The invention relates to the technical field, and provides a detection signal transmission mechanism and a developing cartridge. The detection signal transmission mechanism comprises a shell; a detected part movably arranged on the shell; a transmission wheel rotationally connected to the shell and used for receiving the driving force from a driving force receiving component; and a transmission part. The transmission part and the transmission wheel are coaxially arranged and are synchronously connected, the transmission part is provided with at least one force application part, the force application parts are circumferentially arranged on the transmission part and are used for pushing the detected part to move on the shell, the shell is provided with a separation block, the transmission part is further provided with a separation force receiving part, the separation block is arranged on the motion path of the separation force receiving part and can abut against the separation force receiving part so that the transmission part can be separated from the transmission wheel. Compared with the prior art, the technical problems that an existing tooth-missing gear is complex in structure and high in manufacturing precision requirement and has the jamming risk are solved, the structure is simple and ingenious, and it is guaranteed that detection signals are smoothly transmitted.
Description
technical field [0001] The invention belongs to the technical field of electrophotographic imaging equipment, and more specifically relates to a detection signal transmission mechanism and a developing box. Background technique [0002] The process cartridge is an important part of an electrophotographic image forming device, and is used for photosensitive development for the electrophotographic image forming device. The existing process cartridges include two methods: 1. the photosensitive drum cartridge and the developer cartridge are assembled together to form an integrated process cartridge; 2. the developer cartridge is arranged in the photosensitive drum cartridge to form a split process cartridge. [0003] Usually, in a split-type process cartridge, the developer cartridge can provide developer to the photosensitive drum during printing to develop the electrostatic latent image on the photosensitive drum. When the developer in the developer cartridge is almost exhaust...
