Abstract
A sheet take-out apparatus includes a first separation unit, a second separation unit, a drawing roller for drawing sheets from a nip of the second separation unit, and a pinch roller rotating in contact with it. Overlapping sheets which pass the first and second separation units and are not separated are detected to be overlapped in a state that they are clamped by the nip of the drawing roller and pinch roller. When overlapping is detected, in a state that the rear ends of the overlapping sheets in the conveying direction are restricted by the nip, the drawing roller and pinch roller are stopped and the overlapping sheets are re-separated.
