Abstract
A paper handling device for an image forming apparatus accurately positions paper sheets having been driven out of the apparatus with their center being in register with a reference at a predetermined position for executing stapling or similar processing. The device shifts the discharged paper sheets to a one-side reference position while truing them up at a center reference position. Therefore, the paper sheets are located at the one-side reference position with accuracy and thereby stapled or otherwise processed accurately. The device simplifies the movement of an instrument for implementing such processing. A stack of discharged sheets, whether they are so processed or not, can be readily taken out from the device with no regard to the paper size. A pair of paper guide members urge paper sheets in such a manner as to enhance further accurate positioning of the latter.
