PURPOSE:To improve the installation workability, to simplify the electric wiring, and to increase the reliability of the locking confirmation, by arranging an operator to drive a switch and a transmitter to output the locking signal, and judging the locking condition from the received locking signal. CONSTITUTION:When a rotary gear member 19 and a fixed gear member 20 which compose a crescent lock 16 are engaged each other to fasten the lock, a magnet 22 drives a magnetic access switch 21, and a transmitter 25 outputs a locking condition signal responding to the operation of the magnetic access switch 21. On the other hand, when a dead bolt 29 and a recess 30 which compose a front door lock 26 are geared each other to fasten the lock, a magnet 32 drives a magnetic access switch 31, and a transmitter outputs a locking condition signal responding to the operation of the magnetic access switch 31. These signals are received by a wireless receiver, and a CPU judges the locking condition by the signal input to the receiver. In such a way, since it is not necessary to prepare a transmitting device to deliver the gearing condition of the both gearing members to the opening frame side, but the signal is delivered from the transmitter to the receiver in the wireless means, the electric wiring can be simplified.
