Abstract
A paper feeding device includes a stacking plate for stacking sheets. The stacking plate is movable vertically within a range from a lower limit position to a pick-up position. The stacking plate has a first surface facing the lower limit position and a second surface facing the pick-up position. The paper feeding device also includes a driving device for driving the stacking plate. The paper feeding device has a locking member for locking the staking plate in the lower limit position. The locking member has a deformable section for contact with the second surface of the stacking plate. The deformable section becomes deformed by a driving force applied through the stacking plate as locked in the lower limit position by the driving device, to unlock the stacking plate.
