Abstract

본 발명은 DVCR용 헤드드럼 조립체를 개시한다.The present invention discloses a headdrum assembly for DVCR.

본 발명은, 고정축과; 고정축의 상단부에 압입 설치되며, 그 하부 내면에 스테이터 트랜스가 고정 설치된 상부드럼과; 고정축의 하단부에 그 상단부가 상부드럼의 하단부와 소정간격 이격되도록 고정 설치되며, 그 상부 내측면에 모트 스테이터가 고정 설치된 하부드럼과; 상,하부드럼 사이의 고정축 상에 상,하부 베어링을 통해 베어링 지지된 채 그 상부 내측면에는 상부드럼의 스테이트 트랜스와 소정의 신호를 형성하는 로터 트랜스가 고정 설치되고, 그 하면에는 하부드럼의 모터 스테이터와 소정간격 이격되도록 모터 로터가 고정 설치되며, 그 외측 상면에는 복수개의 헤드가 고정 설치된 회전부재;를 포함하여 된 것으로서, 상,하부드럼이 회전되지 않는 것이어서, 이에 접촉되어 주행하는 테이프의 텐션력 제어가 매우 용이하다. 따라서 회전부재상의 헤드와 테이프간의 안정된 접촉이 이루어져 기록/재생시 화면상의 노이즈를 제거할 수 있는 효과가 있다.The present invention, the fixed shaft; An upper drum which is press-fitted to the upper end of the fixed shaft, and the stator transformer is fixed to the lower inner surface thereof; A lower drum having an upper end fixed to the lower end of the fixed shaft so as to be spaced apart from the lower end of the upper drum by a predetermined interval, and having a mort stator fixed to the upper inner surface thereof; On the fixed shaft between the upper and lower drums, while the bearing is supported by the upper and lower bearings, the upper inner surface is fixed with a state transformer of the upper drum and a rotor transformer for forming a predetermined signal. The motor rotor is fixedly installed so as to be spaced apart from the motor stator by a predetermined distance, and the outer upper surface thereof includes a rotating member having a plurality of heads fixed thereto. Tension force control is very easy. Therefore, a stable contact between the head and the tape on the rotating member is achieved, thereby removing noise on the screen during recording / playback.
