Abstract:
1. A sheet take-out apparatus comprising: a take-out unit adapted to take out a plurality of sheets in a stacked state one by one on a conveying route; a separation unit adapted to shift and separate overlapping sheets taken out by the take-out unit on the conveying route as a preceding sheet and a succeeding sheet, the separation unit being arranged downstream from the take-out unit; an overlapping detector adapted to detect overlapping sheets which have not been separated by the separation unit; and a re-separation unit adapted to re-separate the overlapping sheets detected by the overlapping detector, the re-separation unit including a drawing roller and a second pinch roller positioned downstream from the separation unit to draw out the sheet from the separation unit and a first conveying roller and a first pinch roller positioned downstream from the drawing roller and the second pinch roller, the first conveying roller and the first pinch roller configured to receive a front end of the preceding sheet and convey the preceding sheet, the drawing roller and the second pinch roller configured to decelerate their rotational speed while clamping the rear end of the succeeding sheet, wherein the overlapping detector is configured to detect the overlapping sheets which are clamped and restricted by a nip between the drawing roller and the second pinch roller, the overlapping detector including:
