Abstract

본 발명은 테이프 레코더의 헤드드럼 조립체를 개시한다.The present invention discloses a headdrum assembly of a tape recorder.

본 발명은, 내면에 상, 하 관통구멍이 형성되며, 하부드럼이 베어링 회전축과;회전축에 압입 설치되며 헤드가 고정 설치된 상부드럼과;상부드럼의 상면에 고정 설치되는 모터로터와;하부드럼의 일측면에 나사 고정되고 타단이 상부드럼의 상부를 향하여 연장 형성된 브라켓의 연장부에 고정 설치되는 모터 스테이터와;회전축의 하단부에 고정 설치되는 로터 트랜스와;데크새시상에 고정 설치되며 로터 트랜스와 소정의 신호를 형성하는 스테이터 트랜스를 포함하는 것으로, 로터리 트랜스 즉, 로터 트랜스와 스테이터 트랜스가 드럼의 외측에 위치된 것이어서, 즉, 하부드럼의 직경에 제한을 받지 않는 것이기 때문에 다채널에 따라 쉽게 직경을 넓힐 수 있으며, 특히 회전축이 중공축 구조를 갖고 있어 제품의 경량화를 도모할 수 있다. 또한 상부드럼을 회전축상에 압입 설치하는 것이어서, 헤드의 높이 조절이 용이한 이점이 있다.The present invention, the upper and lower through-holes are formed on the inner surface, the lower drum is a bearing rotating shaft; the upper drum is press-installed on the rotating shaft and the head is fixed; the motor rotor is fixed to the upper surface of the upper drum; and the lower drum A motor stator screwed to one side and fixed to an extension of a bracket formed on the other end of the upper end of the upper drum; a rotor transformer fixed to a lower end of a rotating shaft; It includes a stator transformer for forming a signal of the rotary transformer, that is, the rotary transformer, that is, the rotor transformer and the stator transformer is located on the outside of the drum, that is, because the diameter of the lower drum is not limited by the diameter of the multi-channel easily In particular, since the rotating shaft has a hollow shaft structure, the weight of the product can be reduced. In addition, since the upper drum is press-installed on the rotating shaft, the height of the head can be easily adjusted.
