<p>PURPOSE: To surely separate the lowest paper sheet with an air flow of relatively low pressure and small flow rate blown from the tip side at the time of feeding large size sheets in the lengthwise direction, by constituting a sheet rear end side loading part to be turnable in the vertical direction around a pivot. CONSTITUTION: A double-side unit 19 is provided with an intermediate tray 3 consisting of front and rear trays 3A, 3B, and on these top surfaces, the front and rear sides of a large-size paper sheet S fed in the longitudinal direction are placed. In the center of the front tray 3A, a sheet conveyance part 112 is disposed, and on the rear tray 3B, the rear end regulating plate 4 of the sheet S and respective side regulating plates 9a, 9b are disposed. The rear tray 3B is disposed so as to rotate in the vertical direction around the shaft 20, and is rotated downwards by driving a motor connected to the shaft 20. When the sheets S of prescribed quantity are loaded on a sheet conveyance means 3, a sheet rear end side loading part 3B is set in a condition inclined by a prescribed angle.</p> |
