发明名称 SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS
摘要 A link member is rotatably supported by a lifting plate. When the lifting plate moves upward and downward, the movement of the link member is guided by a guide portion provided on a link guide hole. Before sheet feeding starts, the movement of the link member is regulated by a holding portion provided on a lower end of the guide portion so as to hold the lifting plate in a standby position against a biasing force of a feed spring. When the sheet is fed, a feed cam rotating integrally with a feed roller presses the link member to release the link member from being locked by the holding portion of the link guide hole to thereby make the link member movable along the guide portion.
