비데오 카메라의 스탭 줌회로Staff zoom circuit of video camera

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 회로도.1 is a circuit diagram of the present invention.

Claims (1)

비데오 카메라의 줌 작용을 조정하는 회로를 구성함에 있어서, 스위치(S1)(S2)와 푸쉬 버튼 스위치(P1)(P2)의 상태를 감지하는 키이 인식부(10)의 출력이 펄스 발생 및 조정부(20)를 통하여 모우터 구동부(30)를 구동시켜 모우터(M)를 구동하게 구성한 후 펄스 발생 및 조정부(20)의 출력이 제너다이오드(ZD1)(ZD2)와 접속된 FET(Q1)(Q2)를 구동시켜 모우터(M)의 속도를 제어하는 모우터 속도 조절부(40)를 구성시킨 비데오 카메라의 스탭 줌 회로.In constructing a circuit for adjusting the zoom action of the video camera, the output of the key recognition unit 10 for detecting the state of the switch S 1 (S 2 ) and the push button switch P 1 (P 2 ) is pulsed. After the motor driver 30 is configured to drive the motor M through the generator and adjuster 20, the output of the pulse generator and adjuster 20 is connected to the zener diodes ZD 1 and ZD 2 . A step zoom circuit of a video camera, comprising a motor speed controller 40 for driving the FET Q 1 and Q 2 to control the speed of the motor M. FIG. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
