Abstract: A cartridge top cover includes a drive coupler, a cartridge top cover housing and a rotary cap. Two notches are respectively provided on both sides of a top portion of the cartridge top cover housing, the rotary cap has a toner outlet which is selectively communicated with the notches, a driving member is located inside the cartridge top cover housing, the driving member is in clearance fit with the cartridge top cover housing, the drive coupler is located at the top portion of the cartridge top cover housing, a transmission rod is located at a bottom of the drive coupler, the transmission rod is sleeved through the top portion of the cartridge top cover housing and is connected with the driving member by a one-way bearing which is fixed inside the driving member. The present invention also provides a cartridge including a cartridge body and the cartridge top cover.

Abstract: A stop transmission mechanism includes: a ratchet, wherein elastic teeth are provided on a periphery of the ratchet; a claw provided at a radical side of the ratchet, comprising a fixed end and a moving end which rotates around the fixed end, wherein a claw portion to be engaged with the elastic teeth is provided on the moving end; and a tension spring, wherein one end of the tension spring is fixed, and the other end of the tension spring is mounted on the moving end of the claw, for providing a force which drives the claw portion towards the ratchet; wherein the elastic teeth are made of an elastic material; when the claw portion of the claw is buckled on the elastic teeth by the force of the tension spring, the ratchet is flexibly fixed; when external driving force is large enough, sliding tooth happens.
