Abstract

본 발명의 더블데크 VCR의 스위칭 회로 및 스위칭 방법은 입력되는 동작모드신호에 따라 데크의 동작을 제어함과 아울러 그 데크의 동작에 적합하게 튜너/라인신호 및 데크의 재생신호를 자동으로 스위칭하는 것으로서 종래의 더블데크 VCR은 사용자가 입력스위치 및 출력스위치를 수동으로 절환해야 되는 것으로 사용자는 모드키의 조작과 아울러 스위치를 조작해야되어 번거로움을 주었다.The switching circuit and the switching method of the double deck VCR of the present invention control the operation of the deck according to the input operation mode signal and automatically switch the tuner / line signal and the regeneration signal of the deck to suit the operation of the deck. In the conventional double deck VCR, the user has to switch the input switch and the output switch manually. The user has to operate the switch together with the operation of the mode key.

본 발명은 사용자 모드키를 누름에 따라 그 동작모드에 적합하게 자동으로 두개의 데크의 동작을 제어함은 물론 입력 및 출력스위치를 절환하여 튜너/라인신호 및 데크의 재생신호를 스위칭함으로써 사용자의 조작이 간편하게 된다.The present invention automatically controls the operation of the two decks according to the operation mode by pressing the user mode key, as well as switching the input and output switches to switch the tuner / line signal and the deck playback signal of the user's operation This becomes easy.
