Abstract: Multiple copies of sheets produced by a copying machine or the like are sorted onto trays. The trays are arranged in a stack and are moved upwardly and downwardly to enable different sheets to be sorted onto the trays on each upward pass and downward pass of the stack. The trays have pairs of pins extending outwardly from opposite side edges into a pair of slots on upright support plates. The walls of these slots support each tray as a cantilever. One of the slots, which is closest the rear edge of the trays, is preferably larger than the other and enables any adjacent trays to be spread apart by lifting and tilting one of the trays so as to provide access between the separated trays for jam clearance and the like. A shifting mechanism moves the trays across a gap into which sheets are dispensed from the copier onto the tray at the underside of the gap. This lifting mechanism is a rotatable assembly which engages the pins and moves a tray across the gap.
