たか否かを判断する（Ｓ６）。While the comparator 21 outputs a low level signal to the control means 12 to keep the AC power supply 1 off, the control means 12 can operate by receiving a normal power supply. Then, it is determined whether or not a signal for restarting the operation of the device is received from the remote controller based on the output of the remote controller light receiving unit 13 (S6).
