<p>PURPOSE:To prevent the generation of paper jamming caught by a posterior processing tray, etc., by arranging a discharge roller for a paper sheet on the posterior processing tray, at least on a discharge passage where the part applied with the posterior processing on the paper sheet passes. CONSTITUTION:A rotary shaft 30 is installed in the width direction of a posterior processing tray 5, at the front end part of the posterior processing tray 5, and discharge rollers 31... for assisting the discharge of the paper sheets P... onto a loading tray by a pusher 11 are installed, and at least one of the discharge rollers 31 ... is arranged as a staple discharge roller 31a, at the part applied with the staple treatment on the paper sheets P ..., i.e. on a discharge R on which the staple passes. Accordingly, when passage the paper sheets P... are discharged on the loading tray by the pusher 11, the staple necessarily passes on the smooth discharge roller 31a having the hard surface. Accordingly, the generation of paper jamming due to the trouble that the staple is caught by the posterior processing tray 5, etc., can be prevented, and the discharge of the paper sheets P... on the loading tray can be carried out smoothly.</p> |
