PURPOSE:To restart a conveying apparatus immediately after a power source is recovered by controlling to stop an article to be conveyed at a position to restart the article by an auxiliary power source when a malfunction occcurs in the power source. CONSTITUTION:When an operation unit 5 is operated to input the starting and stopping positions of an article 1 to be conveyed and a start switch is then depressed, a controller 11 turns ON a main power source 12. The controller 11 decides a timing to drive stators 9A-9H, the selection of generating a propulsion force or a reverse propulsion force, and the magnitude of the force from stopping and stopping position information in accordance with a predetermined program, and controls a drive circuit 10 by a control signal a1. If a malfunction occurs in the power source 12, a power source is switched to an auxiliary power source 13, and the article 1 is least stopped at the position where a stator 9 is set. |
