Abstract

본 발명은 테이프 레코더의 릴 구동장치를 개시한다. 본 발명은, 몸체의 외주면에 연장 형성되며, 그 외주면에 기어부가 형성된 제1풀리와; 캡스턴 모터의 하면에 연장 형성되며, 그 외주면에 기어부가 형성된 제2풀리오; 제1,2풀리 사이에 개재되어 각 기어부와 이 맞물림되는 타이밍 벨트와; 메인새시의 일측면 상에 아웃서트에 의해 일체로 성형되는 지지부재와; 지지부재의 상면에 그 일측면에 회동 가능하게 축 지지되며, 그 타단에 가이드 롤러가 회동 가능하게 축 지지된 가압편과; 가압편과 메인새시상에 그 양단이 고정되어 가압편을 상기 타이밍 벨트를 향새 탄성 비이어스 시켜 가이드 로러를 타이밍 벨트의 측면에 가압시키는 스프링을 포함하여 된 것으로서, 타이밍 벨트를 통해 캡스턴 모터로부터의 동력을 릴 풀리로 전달하도록 된 것이어서, 슬립마찰 및 마모를 방지할 수 있엇 구동효율을 향상시킬 수 있으며, 특히 타이밍 벨트의 결합이 매우 용이한 이점이 있다. 따라서 이를 채용한 제품 즉, 테이프 레코더의 신뢰성을 한층 향상시킬 수 있는 효과가 있다.The present invention discloses a reel drive of a tape recorder. The present invention includes: a first pulley extending from the outer circumferential surface of the body and having a gear portion formed on the outer circumferential surface thereof; A second pullio extending from a lower surface of the capstan motor and having a gear portion formed on an outer circumferential surface thereof; A timing belt interposed between the first and second pulleys and engaged with each gear part; A support member integrally formed by an insert on one side of the main chassis; A pressing piece which is rotatably axially supported on one side of the upper surface of the support member and axially rotatably supported on the other end of the support roller; Both ends are fixed on the pressing piece and the main chassis to include a spring for urging the pressing piece to elastically bias the timing belt to press the guide roller to the side of the timing belt, and the power from the capstan motor through the timing belt. Since it is to be delivered to the reel pulley, it is possible to prevent slip friction and wear can improve the driving efficiency, in particular, there is an advantage that the coupling of the timing belt is very easy. Therefore, there is an effect that can further improve the reliability of the product adopting this, that is, the tape recorder.
