Embodiment 1

[0042] Such as figure 1 As shown, the developer cartridge of the present invention includes: a housing 1; an input gear 2 arranged at one side of the housing 1, which can be engaged with a drive head in the imaging device to receive the driving force of the imaging device; The detected component 10 at the same side can be detected by the detection unit in the imaging device. Optionally, since the detection unit in the imaging device may be arranged in any area relative to the developing cartridge installed in the imaging device, the detected component 10 matched with the detected unit in the imaging device may also be arranged on the developing cartridge and Input gear 2 is not on the same side as the rest of the area.

[0043] Such as figure 2 As shown, the housing 1 includes a transmission gear 3 on the same side as the input gear 2 , which can transmit the driving force to the detected component 10 . In this embodiment, the detected component 10 includes a gear componen...

Embodiment 2

[0053] Such as Figure 13 to Figure 16 shown. The difference between this embodiment and Embodiment 1 is that the first elastic member 4 is omitted in this embodiment. In this embodiment, a cover sheet 21 is installed on the top of the mounting column 1a', and an inner wall 20a is provided at a position corresponding to the protective cover 20 and the cover sheet 21, and the diameter of the inner wall 20a is set larger than that of the cover sheet 21. In this embodiment Both the cover sheet 21 and the inner wall 20a are arranged in a circular shape, but may also be arranged in other shapes that are approximately circular. The detected portion 12d' can move circularly in the annular space formed between the cover sheet 21 and the inner wall 20a. The protective cover 20 also includes a toggle part 20b and a track surface 20c. The role of the toggle part 20b is the same as that of the toggle part 6a in Embodiment 1. The rotating head 14 is always pressed by the track surface 20...

Abstract

The invention discloses a developing box which is detachably arranged in an imaging device with a detection unit. The developing box comprises a shell, an input gear, a transfer gear and a detected assembly, wherein the shell is provided with a developing agent accommodation part, the input gear is arranged at one side end of the shell and is used for receiving an external driving force, the transfer gear is used for transferring a driving force of the input gear, the detected assembly comprises a gear part and a detected part, the gear part can be used for receiving the driving force of the transfer gear to rotate, the detected part is detected by the detection unit of the imaging device and is limited to rotate in a rotation direction, a top block is arranged on the gear part and can rotate, and the detected part receives a force of the top block to move and is detected by the detection unit in the imaging device. The gear part is arranged to be a full-tooth gear, and thus, the technical problem that the fabrication cost of the developing box is increased due to the adoption of a tooth-lacking gear in the prior art is solved.

Description

technical field [0001] The invention relates to a developing cartridge. Background technique [0002] The prior art discloses an image forming apparatus such as a laser printer from which a developing cartridge is attached to a main body of the apparatus so as to be detachable therefrom. The developer cartridge contains developer. After the developer in the developing cartridge is used up, the cartridge is removed from the main body of the apparatus. Then, install a new developer cartridge into the main body. [0003] The imaging device is provided with a detection mechanism capable of detecting whether the developing cartridge is brand new or used. [0004] The detection gear is arranged on the side end of this developing cartridge, and it can be detected by the detecting mechanism in the imaging device to verify that the developing cartridge is new. The detection assembly, the driving force receiving part of which is set as a tooth-missing gear including a toothed part...
