Abstract:
A sheet stacking apparatus includes a sheet stacking portion to be mounted into and drawn out of a mounting portion and provided with a side plate including a grip portion by which the sheet stacking portion can be drawn out in the draw-out direction. The sheet stacking portion is supported to be slidable in a draw-out direction by a rail, and the rail is supported to be slidable in the draw-out direction by a rail supporting portion provided in the mounting portion. A rotator is provided on either the rail supporting portion or the rail and disposed in contact with the other of the rail supporting portion and the rail. The rail, the rail supporting portion and the rotator are disposed on one side in the width direction of the sheet stacking portion, and the grip portion is disposed on the other side in the width direction.

Claim (Index 13):
The sheet stacking apparatus according to  claim 1 , further comprising:\n an elastic member provided between the rail and the mounting portion so as to urge the rail in a mounting direction opposite from the draw-out direction; and a first engage portion provided in the rail; and a second engage portion provided in the sheet stacking portion and engageable with the first engage portion, wherein in a case where the sheet stacking portion is moved in the draw-out direction, the first engage portion engages with the second engage portion such that the rail is moved in the draw-out direction together with the sheet stacking portion while resisting against elastic force of the elastic member, and wherein in a case where the sheet stacking portion is moved in the mounting direction, the rail is moved in the mounting direction in a state where the first engage portion is kept engaged with the second engage portion due to elastic force applied from the elastic member.
