Abstract
In a sheet finishing apparatus of the present invention, when temporarily loading a plurality of sheets of paper on a standby tray until a processing tray finishes processing, to prevent a sheet of paper loaded first from being pressed out by a sheet of paper ejected later, a chuck for retaining the rear ends of the sheets of paper is installed on the downstream side of the standby tray, and for curled sheets of paper, a standby tray guide and an arm member for suppressing curling of the central part of the sheets of paper are installed, thus matching on the standby tray is stabilized.
