<p>PURPOSE:To prevent a bundle of sheets from slipping off from a stack tray in spite of progress of loading to the stack tray or increase of a spacing between an intermediate tray and the stack tray. CONSTITUTION:In the downstream part against a conveying roller of an intermediate unit 210, a Mylar guide sheet 250, in which one end part, is fixed in a stack tray 220 while the other end part. is fixed in a winding reel 252 including a spiral spring (unshown in a figure), extends in the width direction in a position of no interference with discharge of a sheet and is spread via a relay roller 251 moving with an intermediate tray 211. Energizing force (arrow direction) of the spiral spring is always applied to the winding reel 252, so that the guide sheet 250 can be extended/shrunk while keeping tension. In other words, the intermediate tray 211 and the stack tray 220 are linked together via the guide sheet 250.</p> |
