Abstract

본 발명은 차량 속도계용 센서에 관한 것으로, 특히 트랜스미션 회전축과 연동되어 같은 회전수로 회전하는 속도계용 회전체(3)의 날개(4) 부위가 포토커플러(10)의 광통로(11)에 위치토록 구성하고, 포토커플러(10)의 수광 포토트랜지스터(13) 출력단에서 날개(4) 회전에 따른 펄스를 수득하여 속도계에 제공케 함으로서 출력퍽스가 정확해지고 속도계 시스템도 간단해지도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor for a vehicle speedometer, and in particular, a portion of a blade (4) of a speedometer rotating body (3) which rotates at the same rotational speed in association with a transmission axis of rotation is located in the optical path (11) of the photocoupler (10). In this configuration, the output pulse is accurate and the speedometer system is simplified by obtaining a pulse according to the rotation of the blades 4 at the output end of the light receiving phototransistor 13 of the photocoupler 10 and providing it to the speedometer.
