摘要：
A sheet stacking unit that stacks sheets thereon is movable up and down. A lifting unit moves the sheet stacking unit up and down. A driving unit drives the lifting unit. A control unit controls a driving speed of the driving unit. A position detecting unit detects a position of the sheet stacking unit in an up-and-down direction. The control unit controls the driving speed according to the position of the sheet stacking unit detected by the position detecting unit.
