<p>PROBLEM TO BE SOLVED: To prevent a sheet from being taken out by a carrier belt by surely handling several sheets of the upper-order of a sheet bundle loaded on a tray and separating the sheets into each one. SOLUTION: Air a1 is blown from a nozzle 103-1 toward an end face on the side of a carrier direction tip of a sheet bundle S3 loaded on a tray 104. By this air a1, the sheet bundle S3 is handled and is separated into each one. A suction duct 111 sucks the upper-order sheets of the bundle S3 and the sheets are sucked by a carrier belt 110. Air a2 blown from a nozzle 103-2 separates sheets except the top sheet from plural sheets sucked by the carrier belt 110. But a fold and a curl are formed on the side of the carrier direction tip of the sheet bundle S3, several sheets of the upper-order of the sheet bundle S3 are not separated into each one by air a1. Therefore, when air a1 is blown from the nozzle 103-1, the side of the carrier direction tip of the sheet bundle S3 is oscillated in the loading direction of the sheet bundle S3 by an oscillating tray 124 in this case.</p> |
