Abstract:
A sheet feeding apparatus includes a sheet containing unit and a sheet feeding device to feed sheets in the sheet containing unit. The sheet containing unit includes a main body to hold sheets, a drawer member capable of being drawn from the main body, a restricting member movable in a direction parallel to a sheet feeding direction, a first retaining member disposed at the main body, and a second retaining member disposed at the drawer member. The drawer member holds the sheets together with the main body when drawn from the main body. The restricting member restricts an upstream end position of the contained sheets. The first retaining member retains the restricting member at a first position. The second retaining member retains the restricting member at a second position.

Claim (Index 1):
A sheet feeding apparatus comprising:\n a sheet stacking unit configured to stack a sheet; a cassette main body configured to support the sheet stacking unit; a regulating device disposed at the sheet stacking unit to be movable in a first direction and in a second direction opposite to the first direction, and configured to regulate an end position of the sheet; a plurality of first engaged portions disposed at the cassette main body in a direction parallel to a direction in which the regulating device moves; and a plurality of second engaged portions disposed at the cassette main body in the direction parallel to the direction in which the regulating device moves, wherein the plurality of second engaged portions are disposed at positions different, in a direction intersecting the direction in which the regulating device moves, from positions at which the plurality of first engaged portions is disposed; wherein the regulating device includes: a holding member, a lever disposed rotatably at the holding member and configured to be operated, a first engaging portion movable in a vertical direction and configured to engage with the plurality of first engaged portions, an urging spring, a second engaging portion configured to be urged by the urging spring to engage with the plurality of second engaged portions, and an action surface disposed at the lever and configured to move the first engaging portion in an upper direction by the lever being rotated, wherein, as seen from an axial direction intersecting the direction in which the regulating device moves in a state in which the first engaging portion engages with the plurality of first engaged portions, the action surface is disposed between an operation surface, on which a user performs operation, of the lever and another surface of the lever opposite to the operation surface.
