ABSTRACT:
A finisher for use with a copier, printer or similar image forming apparatus for stapling or otherwise finishing paper sheets sequentially driven out of the apparatus. The paper sheets entering the finisher one after another are collected on a tray. A paper sorting mechanism moves the tray in a reciprocating motion in a horizontal plane in a direction perpendicular to an intended direction of paper discharge onto the tray. The paper sorting mechanism has a paper pressing member movable in a reciprocating motion in interlocked relation to the tray, a paper positioning member for urging the paper sheet discharged onto the tray to a predetermined position, a drive source for causing the tray into a reciprocating motion, and a drive source for driving the tray in the vertical direction such that the tray receives paper sheets at an optimal level. A height sensor is associated with the paper pressing member for determining that the paper sheets sequentially stacked on the tray has reached a predetermined height.
