Claims (1)

시스콘 출력단(SYCON OUT)으로부터 나오는 모우터 선택 전압을 구동전압으로 변환시키는 시스콘 출력 드라이브회로(1)의 입력일측에 호울집적회로의 계수신호(HOLE ICCOUNT)를 전압으로 변환시키는 호울집적회로 출력변환회로(2)를 연결하고; 시스콘출력 드리이브회로(1)의 출력전압을 연산증폭회로(3-1)에 인가하여서, 궤환되는 리일모우터(M1)의 구동전압과 비교되도록 하고; 발진회로(3)의 25㎑ 톱니파 발진출력과 연산증폭회로(3-1)의 출력을 비교기회로(4)에 인가하여 출력되는 구형파의 폭이 비데오 테이프의 권취량에 따라 적절히 조정되도록 하고; 비과기회로(4)의 출력단에 파워트랜지스터(TR4)를 결합시키되 파워트랜지스터(TR4)의 출력을 전술한 연산증폭회로(3-1)에 궤환시켜서 리일모우터(M1)의 구동전압 변동을 발지할 수 있도록 하고; 파워트랜지스터(TR4)의 출력일단에는 스위칭 트랜지스터(TR5∼TR13)를 구비하여 리일모우터(M1)에 정역동작전압를 공급하는 리일모우터 정역스위칭회로(5)를 연결하여서 된 영상신호 기록재생장치의 리일서어보 시스템.Hole integration for converting the count signal (HOLE ICCOUNT) of the hole integrated circuit to a voltage on one side of the input of the sheath output drive circuit 1 for converting the motor selection voltage from the SYCON OUT to the drive voltage. A circuit output converting circuit 2 is connected; An output voltage of the sheath output drive circuit 1 is applied to the operational amplifier circuit 3-1 so as to be compared with the drive voltage of the feedback real motor M1; Applying the 25 kHz saw tooth oscillation output of the oscillation circuit 3 and the output of the operational amplifier circuit 3-1 to the comparator circuit 4 so that the width of the square wave output is appropriately adjusted according to the winding amount of the video tape; The power transistor TR4 is coupled to the output terminal of the non-overheater circuit 4, and the output of the power transistor TR4 is fed back to the above-described operational amplifier circuit 3-1 to detect a change in the driving voltage of the real motor M1. To do so; A video signal recording and reproducing apparatus, comprising a switching transistor TR5 to TR13 at an output end of the power transistor TR4, connected to a real motor forward / reverse switching circuit 5 for supplying a forward and reverse operating voltage to the real motor M1. Real servo system. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
