PURPOSE:To reduce the power consumption of a remote power source which is operated in the holding state, by detecting the rise of the remote power source and turning on a main power source to operate a control part and turning off the main power source after initialization. CONSTITUTION:The remote power source which is turned on by only a power switch SW drives only a display part 6 in the holding state. A main power source 2 which drives a control part 7 is turned on by a flip flop 3 which is set by an OR gate 4, and they are made operated by the remote power source. A remote control signal RC and the output of a rise detecting circuit 5 of the remote power source 1 are applied to the OR gate 4, and the rise detection signal is applied to the control part 7 also through a flip flop 8, and the control part 7 initializes the display part 6 only when the rise of the remote power source is detected. |
