Abstract:
The sheet feeding apparatus includes a first cursor. The first cursor comes in contact with a side face of a stack of sheets, and can move between a restriction position and a retracted position. The lift plate includes a fixed plate and a movable plate. The stack of sheets is movable together with the movable plate in the push-in/pull-out direction. When the sheet storage unit is pushed into the apparatus body, the first cursor moves by inertia of the stack of sheets, against an urging force of an urging member, toward the retracted position. After the sheet storage unit has reached the accommodated position, the first cursor pushes the stack of sheets by resilience of the urging member to move to the restriction position.

Claim (Index 1):
A sheet feeding apparatus comprising:\n an apparatus body; a sheet storage unit which is opened to an upper side and has a storage space for storing a stack of sheets, the sheet storage unit being able to be pushed into and pulled out of the apparatus body; a lift plate which is disposed parallel to a bottom of the storage space and can be raised and lowered; a lift unit which raises and lowers the lift plate; a first cursor which is provided upright on the bottom at a back side with reference to a push-in direction in which the sheet storage unit is pushed into the apparatus body, the first cursor restricting an end, in the back side, of the stack of sheets; and an urging member disposed between a back side wall and the first cursor to urge the first cursor, the back side wall defining an end in the back side of the storage space, the urging member being elastically deformable in a push-in/pull-out directions, wherein the first cursor comes in contact with a first side face, which is a side face of the stack of sheets, and is movable between a restriction position where the first cursor restricts the stack of sheets from moving in the push-in direction and a retracted position to which the first cursor retracts in the back side from the restriction position, the lift plate includes a fixed plate connected to the lift unit and a movable plate on which the stack of sheets is placed, the movable plate being movable on the fixed plate in the push-in/pull-out direction, and by inertia force of the stack of sheets, which generates when the sheet storage unit is pushed into the apparatus body and stops at a predetermined position, the stack of sheets moves together with the movable plate to the back side of the storage space to push the first cursor, the first cursor moves, by the inertia against an urging force of the urging member, toward the retracted position and then moves, pushing back the stack of sheets, by resilience of the urging member to the restriction position.
