Title: Toner cartridge
Inventor: WANG YUBUN
IPC: G03G21/18
Filed: 2020-11-30
Abstract: To provide a configuration that can achieve movement of a shutter and rotation of a conveying member with a driving force supplied from one coupling.SOLUTION: A toner cartridge comprises: a toner coupling 321; a shutter 16; a sun gear 351; a planetary gear; a rotating plate 352; and a boss. When the shutter is located at a closed position, the boss is located at a first position. In this state, the boss and the shutter rotate together with the rotating plate 352. Thus, in association with the rotation of the toner coupling, the shutter moves from the closed position to an open position. When the shutter moves from the closed position to the open position, the boss moves from the first position to a second position. The boss thus separates from the rotating plate. Thus, the planetary gear and the sun gear idle. The conveying member can therefore be rotated while maintaining the shutter at the open position.SELECTED DRAWING: Figure 7
