SOLUTION: While maintaining the state of fitting the projection part 6 of a transmitter 5 to a recessed part 3 provided on a receiver 2 and electrically connecting contactors 3a and 6b with each other, the switch 7 (7a or 7b) of the transmitter 5 is pressed and an unlocking signal is sent out to the receiver 2. The receiver 2 analyzes the unlocking signal and issues an unlocking command when it is confirmed that it is a true signal. For the switch 7, there are two kinds which are the one 7a for a frame body and the one 7b for a glass door and either one is selected. COPYRIGHT: (C)2004,JPO
