<p>A sorter includes a shifting mechanism for sequentially shifting the receptacles (12) and for holding each receptacle shifted in an open position which the articles to be treated may be placed on the receptacle. The shifting mechanism is provided with a pair of Geneva wheels (401, 402, 421, 422) each having at least one groove (40C1, 40C2, 42C1, 42C2) formed therein on a predetermined phase condition. The shifting mechanism further includes a first guide slot (10C, 10D) to vertically movably align and guide the pins (12G, 12H) of each receptacle (12), and a second guide slot (10C, 10D) continuous to the first guide slot, the second guide slot being adapted to laterally guide a pin (12G, 12H) of one of the receptacles for drawing out the one receptacle. The pin (12G, 12H) of the one receptacle is biased by a biasing mechanism against the outer circumferential surfaces of the Geneva wheels. The receptacles are received in a receptacle carrier (15), and the receptacle carrier (15) is vertically movably arranged. A restraining mechanism (16D, 16F, 18D, 18F) is provided to the receptacle carrier (15) for restraining the pins (12G, 12H) in the first guide slot in contact with adjacent pins. <IMAGE></p> |
