Since it is consumed, the effect of reducing power consumption in the standby state is not sufficient. Further, in order to adopt the first to fourth conventional techniques, hardware having a special operation mode such as a sleep mode is required, which leads to an increase in cost. Therefore, the present invention can be applied to a general microcomputer, and an object thereof is to further reduce power consumption by not applying a voltage to the microcomputer and its peripheral circuits during standby.

Q2 and Q3 are turned off, the power supply from the power supply to the microcomputer 1 is cut off, and the power consumed by the microcomputer 1 is reduced. In such a standby state, when the remote control light receiving unit 2 receives an infrared signal and outputs a remote control signal, the transistor Q1 is turned on in synchronization with the remote control signal, and the capacitor C1 is charged via the diode D1.
The base potential of the transistor Q2 rises. At this time, in the case of a malfunction such as noise, the electric charge stored in the capacitor C1 is discharged by the resistor R1 connected in parallel with the capacitor C1, so that the base potential of the transistor Q2 does not rise sufficiently, and Q2 is ON
There is nothing to do.

供給は停止され再び待機状態に戻る。When the remote-control light-receiving unit 2 outputs a normal remote-control signal, the base potential of the transistor Q2 rises appropriately and the transistor Q2 turns on. When the transistor Q2 turns on, the base potential of the transistor Q3 drops, the transistor Q3 turns on, and the microcomputer 1 is supplied with power from the power supply. The microcomputer 1 starts up because it receives power supply, raises the output voltage of the POWER terminal, turns on the transistor Q4, and maintains the activated state. next,
The microcomputer 1 decodes the remote control signal input to the R / C signal input terminal. As a result, if the signal keeps the starting state of the microcomputer 1, the output voltage of the POWER terminal is maintained and the starting state is maintained. . If the result of decoding indicates that the signal does not maintain the activated state, the output voltage of the POWER terminal is lowered and the transistor Q3 is turned off.
When the transistor Q3 is turned off, the power supply to the microcomputer 1 is stopped and the standby state is restored again.
