ABSTRACT:
A sorter includes a plurality of vertically movable trays which are each formed with a cut-out in one corner. The trays are supported so that the corners in which the cut-outs are formed are lower than the other corners of the tray. Rear and side walls flank the cut-outs. Due to the skewed angle of the trays sheets which are ejected thereonto slide under their own weight to the corners in which the cut-outs are formed. A tray shift mechanism includes groups of two Geneva wheels each formed with one or more recesses which can pick-up tray pins and guide the same along guide slots. The guide slots are formed with shaped portions which induces one tray at a time to be moved laterally to a position wherein sheet collection or stapling can be carried out. A spring loaded stopper cooperates with each set of two Geneva wheels and holds the pins which have been carried to a laterally displaced position by one wheel, against the periphery of the wheels ready for pick up by the other wheel.
