Claims (1)
- 베이스에 바이어스가 인가되어 있는 제1의 트랜지스터의 콜렉터 및 에미터에 각각 저항을 접속하고, 이 제1의 트랜지스터의 콜렉터와 제2의 트랜지스터의 베이스와의 사이 및 제1의 트랜지스터의 에미터와 제2의 트랜지스터의 에미터와의 사이에 각각 콘덴사를 접속하여 구성한 에미터 결합형의 멀티바이브레이터에 있어서, 상기 제2의 트랜지스터의 콜렉터에 공진회로를 접속해서 상기 제2의 트랜지스터가 도통하고 있을때 멀티바이브레이터의 반복주파수보다 높은 주파수로 발진하는 신호로 빛 등의 신호를 높은 주파수로 변조하고, 이 높은 주파수로 변조된 신호를 다시 낮은 주파수로 단속 변조한 것을 원격제어용신호로서 사용하는 것을 특징으로 한 원격제어장치.
