Abstract
An automatic paper feeder presses the surface of copying paper loaded on a paper loading plate in a paper cassette against a paper feeding roller, and feeds the paper sheet by sheet in accordance with the rotation of the roller. When a paper detector provided at a downstream side of the roller does not detect the paper within a specified period of time after starting a paper feeding operation, the automatic paper feeder rotates the roller in the reverse direction, at the same time releasing the pressure between the paper and the roller, and then increases the pressure and rotates the roller in the forward direction to restart the paper feeding operation.
