Abstract

PURPOSE: To promote watt-saving at the time of unlocking by transmitting a signal via a carrier medium selected in response to the extent of setup environment, and having a main power circuit turned to ON only in time of using it through a signal interchange. CONSTITUTION: When a carrier of a hand console 2 pushes the knob of a hinged door equipping a corresponding locking device 1 and being locked, an ON-OFF switch 16 is turned to ON, transmitting a trigger signal (e) from a transceiver part 27. In this case, the handconsole 2 turns a main power circuit 11 to ON, transmitting identifying signal (a), and then it receives a discriminative process of this signal by the locking device. In consequence, an actuator of a lock mechanism 7 operates, shifting this lock mechanism 7 to the left, whereby unlocking operation is ended. When the door opened in time of locking is reset to a door frame anew, a sensor 20 is turned to ON, outputting a locking normal state detecting sensor signal (f), and at a time when locking is made possible, a check signal (g) and a load control signal (d) are outputted in succession, operating a driver of the lock mechanism 7, and thus the locking is completed.
