<p><P>PROBLEM TO BE SOLVED: To provide a lock control device where voltage drop in a control circuit is small, size reduction and weight reduction are allowed, and malfunction does not occur even when the power supply is inversely connected. <P>SOLUTION: The lock control device 10 moves and operates a moving member to a locking position or an unlocking position with a magnetic force of a magnet. The lock control device comprises a control part 13 for issuing a command of locking or unlocking, an attraction coil 14 for supporting the moving member at the locking position by conduction, a reset coil 14' for supporting the moving member at the unlocking position by conduction, a locking FET 15 for conducting the attraction coil 14 with the locking command from the control part 13, an unlocking FET 15' for conducting the reset coil 14' with the unlocking command from the control part 13, and a relay 18 for opening or closing a locking circuit 16 comprising the attraction coil 14 and the locking FET 15 and an unlocking circuit 16' comprising the reset coil 14' and the unlocking FET 15'. <P>COPYRIGHT: (C)2003,JPO</p> |
