PROBLEM TO BE SOLVED: To unlock a lock when an operator carrying a transmission/reception key merely touches a touch sensor. SOLUTION: An activation signal 40 is transmitted from an activation signal transmitting antenna 35 by an input from the touch sensor 31. When the activation signal 40 is received by an activation signal receiving antenna 23 provided on the transmission/reception key 21, the transmission/reception key 21 is shifted to an active mode, and communications are started between the transmission/ reception key 21 and a main body section 22. When the main body section 22 confirms that the identification number 41 of the transmission/reception key 21 is an unlocking permission number registered in advance, it outputs an unlocking signal to an unlocking signal output terminal 38, thereby the lock can be unlocked when the operator carrying the transmission/reception key 21 merely touches the touch sensor 31. |
