Abstract
A sheet feeding apparatus includes a first detection device that outputs a first signal upon detecting a stacked sheet and outputs a second signal upon detecting no sheet, and a second detection device that outputs a third signal when a sheet stacking member is above a predetermined position and outputs a fourth signal in a case where the stacking member is below the predetermined position A control unit controls movement of sheet stacking member by restricting movement of the stacking member when the second signal is output and the third signal is output when power of the sheet feeding apparatus is turned on. The second detection device includes a switch that emits the third signal while abutting a moving member that moves with the sheet stacking member and emits the fourth signal while being separated from the moving member.
