Patent ID: 8641042

Claim:
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 configured to clamp and stop, decelerate, or reversely rotate a rear end of the succeeding sheet detected by the overlapping detector along a conveying direction to re-separate the overlapping sheets, the re-separation unit including: a drawing roller and a second pinch roller arranged downstream from the separation unit to draw out the sheet from the separation unit, and a conveying roller arranged downstream from the drawing roller and the second pinch roller, the conveying roller being arranged to receive a front end of the preceding sheet and to convey the preceding sheet, a second conveying roller rotating in contact with the sheets drawn from the separation unit by the drawing roller and the second pinch roller; and a compressing member which is arranged opposite to the second conveying roller via the conveying route and compresses the sheets against the second conveying roller, wherein the re-separation unit operates such that the rotational speed of the drawing roller is stooped, decelerated, or reversely rotated while the drawing roller and the second pinch roller clamps the rear end of the succeeding sheet, and wherein the compressing member clamps the sheet between the compressing member and the second conveying roller with force weaker than clamping force by the drawing roller and the second pinch roller.
