Abstract
A sorter comprising a plurality of vertically arranged bin trays. The bin trays have widthwise projecting trunnions at least in one side thereof. The trunnions are stacked vertically and can move in the stacking direction along a predetermined moving passage. The sorter further comprises a transfer mechanism for elevating and lowering the trunnions successively one by one along the predetermined transfer passage and successively spacing adjacent bin trays vertically at their sheet receiving ends to form a sheet receiving opening. The transfer mechanism has a pair of cooperating rotating cam plates. Each of the rotating cam plates has at least one trunnion receiving groove extending radially and being opened at its radial outside end and an outer circumferential cam surface continuously extending circumferentially excepting the site of the trunnion receiving groove. The outer circumferential cam surface is a convoluted surface whose radius progressively increases in a predetermined rotating direction.
