<p>A sorter comprising a plurality of vertically arranged movable bin trays (56A-E) and a transfer mechanism (87) for elevating and lowering the bin trays successively. Follower projecting portions (86A-E) projecting in a predetermined direction are provided respectively in the bin trays (56A-E), and the projecting lengths of the projecting portions are larger stepwise from the bottom to the top of the bin tray arrangement. The transfer mechanism (87) includes ring-like cams (92) disposed opposite to the follower projecting portions (86A-E) so as to be free to rotate about a central axis extending in the predetermined direction and to move in the direction of the central axis, with its extending length forwardly in the direction of the central axis progressively increasing from a given angular part in a predetermined rotating direction, and driving means (122) or rotating the cam (92) in the predetermined rotating direction and moving it forwardly in the direction of the central axis and also for rotating it in a reverse rotating direction and moving it rearwardly in the direction of the central axis.</p> |
