Claims12
A feeding device that feeds a sheet, the feeding device comprising:
- a feeding cassette including a stack member on which the sheet is stacked, the feeding cassette being detachable from a main body of an apparatus;
- a driving unit configured to generate a driving force of forward rotation and a driving force of reverse rotation;
- a feeding member configured to feed the sheet stacked on the stack member by rotating in contact with the sheet and provided to be rotated by the driving force of forward rotation from the driving unit;
- a holding member configured to hold the feeding member;
- a first lever configured to move the feeding member via the holding member, wherein the first lever moves said feeding member between a contact position in contact with the sheet stacked on the stack member and a retracted position retracted upward from the contact position;
- a second lever configured to move said holding member by acting on the first lever, wherein the second lever positions the feeding member at the contact position in a case where the feeding cassette is attached to the main body and positions the feeding member at the retracted position in a case where the feeding cassette is pulled out from the main body;
- and
- a moving unit configured to move the feeding member located at the contact position to the retracted position by the driving force of reverse rotation from the driving unit and to move the feeding member located at the retracted position to the contact position by the driving force of forward rotation from the driving unit, the moving unit acting on the first lever at a position different from the second lever.
