Abstract

PURPOSE: To secure an automatic control for the operation of the TV picture receiver main body part according to the operation state of the voice remote transmission/reception device and without coming near the TV picture receiver main body.
CONSTITUTION: With operation of the TV picture receiver, the aural signals are obtained via antenna 21 of the main body part, aural circuit 24 and others. These aural signals are FM-modulated by modulation circuit 27 and then transmitted by light emitting diode 29 and via driving circuit 28 in the form of the infrared rays. The infra-red rays are demodulated and amplified through light reception part 1, demodulation circuit 3 and others to be supplied to earphone jack 5. The light supplied to jack 5 is detected at detection circuit 6, and oscillation circuit 7 is excited for a short time. Thus the signal of frequency f1 is delivered through ultrasonic speaker 11 to be received at ultrasonic mike 12 and then to be delivered through synchronous circuit 14. Thus, FF20 is reset, and relay 25 is released to separate the speaker of the main body. And with removal of the earphone, another frequency signal is delivered to secure the original state.
