Abstract:
A feeding apparatus includes a sheet supporting member, a feeding member, and a lift unit. The lift unit lifts and lowers the sheet supporting member to abut a sheet stacked on the sheet supporting member against the feeding member. The lift unit includes an urging member that biases the sheet supporting member towards the feeding member, a moving member that moves in a first direction different from a sheet supporting member lifting direction, and a contact member in contact with the moving member. The contact member includes a curved cam surface in a region that comes in contact with the moving member. A contact state between the moving member and the contact member is changed by moving the moving member in the first direction and the curved cam surface. Regarding changing the contact state, the sheet supporting member can be moved to a feed position and a retracted position.
