ABSTRACT:
A sorter includes a plurality of vertically movable trays which are each formed with a cut-out in one corner. The trays are each oriented so that a corner in which the cut-out is formed is lower than the other corners of the tray and formed with a rear wall a side wall which flank the cut-out. A tray shift mechanism includes groups of three Geneva wheels. These wheels are each formed with one or more recesses which can pick-up tray pins and guide the same along guide slots. The slots are formed with portions which induce both vertical and lateral displacement of one or more trays at a time. The Geneva wheel/guide slot arrangements move the trays one by one to a position wherein sheet of printed matter can be ejected thereonto and/or the cut-outs are located in the mouth of a stapler. Due to the skewed angle of the trays the ejected sheets slide under their own weight to the corners in which the cut-outs are formed.
