Abstract
PURPOSE: To enable to perform ON-OFF control for the function of power supply switch with the remote control transmitter, for the power supply circuit having the power supply switch function of electronic unit.
CONSTITUTION: When the main power switch 6 is turned on in advance, the voltage E1 rectified and smoothed at the smoothing circuit 7 is fed to the amplifier 2, signal separation circuit 3, wave shape circuit 4, and flip flop 5 to keep them in waiting condition. When the remote control signal from the remote control transmitter is received at the receiver 1, it is amplified at the circuit 2, the power supply ON-OFF signal is separated and shaped into one short signal at the circuit 4, the flip flop 5 is inverted. Thus, the transistor Q4 of the ON-OFF control circuit 9 and diodes D7 and D8 are cut off, the transistors Q1, Q3 of the voltage stabilization circuit 8 are turned on, DC output voltage is led out at the output terminal T1, the power supply is tutned on, and it is turned off when the remote control signal is received further.
