VTR의 화면 정지 제어회로에 있어서, 캡스턴 모우터와 릴 모우터를 별도로 구동시키면서 화면정지 조작시 인가되는 신호펄스에 의하여 캡스턴 모우터를 필요에 따라 정 또는 역회전시키고 솔레노이드 가압장치로 정지마찰력을 증가시킨후, 노이즈바를 제거하도록 모우터를 구동시키며 프레임 이동시에는 신호펄스에 의하여 한 프레임씩 이동하도록 구성시킨 화면 정지시 캡스턴 모우터 제어회로.In the screen stop control circuit of the VTR, the capstan motor and the reel motor are driven separately and the capstan motor is rotated forward or backward as needed by the signal pulse applied during the screen stop operation, and the stop friction force is increased by the solenoid pressurization device. And a capstan motor control circuit configured to drive the motor to remove the noise bar and to move the frame one frame by signal pulse when the frame moves. 제1항에 있어서, 기판(10)의 축핀(11)으로 축착된 작동대(12)의 후단에 솔레노이드(9)를 연설시키고 슬립판(13)이 일단에 형성되고 타단을 작동대(12)와 스프링(14)으로 탄지시킨 정지대(15)를 작동대(12)의 첨단에 핀(11)으로 축착시키어 된 솔레노이드에 의한 캡스턴 모터의 슬립 가압장치.The solenoid 9 is extended to the rear end of the operating table 12 which is constricted by the shaft pin 11 of the substrate 10, and the slip plate 13 is formed at one end and the other end of the operating table 12. And a pressurization device of a capstan motor by a solenoid in which a pin 11 is condensed on a tip of the operating table 12 with a stop 15 held by a spring 14. ※참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: This is to be disclosed based on the first application.
