Abstract:
1. A sheet take-out apparatus, comprising: a sheet take-out unit configured to take out a plurality of sheets in a stacked state one by one on a conveying route; a separation unit configured to shift and to 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 configured to detect overlapping sheets that have not been separated by the separation unit; and a re-separation unit configured to re-separate the overlapping sheets detected by the overlapping detector, being arranged downstream from the separation unit, the re-separation unit including: wherein the re-separation unit operates such that the rotational speed of the drawing roller is stopped, decelerated, or reversely rotated while the drawing roller and the pinch roller clamp a rear end of the succeeding sheet, and wherein the separation unit includes a first and second separation portion, the first separation portion having a first feed roller and a first separation roller opposite to the first feed roller to apply a first separation force to the overlapping sheets, and the second separation portion having a second feed roller and a second separation roller opposite to the second feed roller to apply a second separation force to the overlapping sheets.
