<p>PURPOSE:To hold safely a cartridge, by storing the goods by a picker in case the extraction of goods is not detected by a position detector when the goods are picked out and moved back by the picker. CONSTITUTION:When the goods are picked out, a magnet fault detecting signal SG5 is sent to a storage sequence control circuit 17 from a pick-up sequence control circuit 13. Then the signal SG5 is delivered from the output of a position detecting circuit 11 when the circuit 13 is in a take-up/retard state and when S1, S2 and S3 of the position detector 11 are on, off and on respectively. Receiving the signal SG5, the circuit 17 turns on a picker motor forward driving circuit 14 to move forward a picker 4F and at the same time turns off a picker magnet driving circuit 15 when it is detected by the output of the circuit 11 that the picker 4F reaches a cell 1. Then a picker motor backward driving circuit 16 is turned on to move back the picker for storage.</p> |
