Abstract

When a pick-up roller is lowered to contact with a sheet, a control means stops a tray drive motor to prohibit a lifting movement of a sheet stacking tray to thereby minimize bounding of the pick-up roller when the pick-up roller abuts against the sheet and preventing delay in sheet supply and occurrence of sheet jam.
