Abstract
A sorter comprising a plurality of vertically arranged movable bin trays and a transfer mechanism for elevating and lowering the bin trays successively. Follower projecting portions, projecting in a predetermined direction, are provided respectively on the bin tray. The projecting lengths of the projecting portions increase stepwise from the bottom to the top of the bin tray arrangement. The transfer mechanism includes ring-like cams disposed opposite to the follower projecting portions so as to be free to engage the follower projecting portions and to rotate about a central axis extending in the predetermined direction and to move in the direction of the central axis, with the length of the cam extending forwardly in the direction of the central axis, progressively increasing from a given angular point in a predetermined rotating direction, and a driving unit for rotating the cam in the predetermined rotating direction, causing the cam to move forwardly in the direction of the central axis and also for rotating the cam in a reverse rotating direction by that distance rearwardly in the direction of the central axis.
