Claims (1)

모노 멀티 바이브레이터(1)를 거쳐 30H2신호와 분주기(2)를 거친 15H2신호가 조합되는 4헤드 스위치 로직(3)과, 이 4헤드 스위치 로직신호중 로터리 이레이즈 헤드와 동기를 맞추어 소거할 수 있게 구성된 플립플릅(FF1)과, 플라잉 이레이즈 헤드로 비디오 트랙을 소거 한 후 CH1비디오 헤드가 동기를 맞추어 녹화로 들어 갈 수 있게 구성된 플립플롭(FF2)과 녹화스위치(SW1)가 온될때에만 실제의 로터리 이레이즈신호와 비디오녹화 CTL2 신호가 동작되게 하는 트랜지스터(Q1)(Q2) 및 상기 플립플릅(FF1)(FF2)의 리셋(R)단에 접속되는 앤드게이트(AND)로 구성됨을 특징으로 하는 무비용 4헤드 스위치 드럼의 로터리 이레이즈 회로.The four-head switch logic (3), which combines the 30H 2 signal through the mono multivibrator (1) and the 15H 2 signal through the divider (2), and the four-head switch logic signal can be erased in synchronization with the rotary erase head. A flip-flop (FF 1 ) configured to be configured, and a flip-flop (FF 2 ) and a recording switch (SW 1 ) configured to allow the CH 1 video head to enter recording in synchronization after erasing the video track with a flying erase head. The AND connected to the reset (R) terminal of the transistor (Q 1 ) (Q 2 ) and the flip-flop (FF 1 ) (FF 2 ) for operating the actual rotary erase signal and the video recording CTL2 signal only when it is turned on. Rotary erasure circuit of a four-head switch drum for movie, characterized in that consisting of a gate (AND). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
