装置。 In a paper feeding device that is equipped with a vertical mechanism for a bottom plate on which sheets of paper are loaded, and that maintains a constant height of the top of the paper placed on the bottom plate and detects when the paper runs out, a pair of light emitting elements and a a detector comprising a light receiving element; a first light shielding means for shielding the detector from light when the top of the sheet of paper placed on the bottom plate reaches a predetermined position; and the sheet of paper placed on the bottom plate disappears. and a second light shielding means for shielding the detector from light, and detecting paper out when the bottom plate is lowered by a predetermined amount at the time of starting paper feeding and the detector is in the light shielding state, and detecting the paper out at other times. A paper feeding device characterized by comprising a control means for raising the bottom plate until the container is in a light-shielded state.
