Abstract

본 발명은 헤드드럼 조립체의 정전기 접지장치를 개시한다.The present invention discloses an electrostatic grounding device for a head drum assembly.

본 발명은, 헤드드럼의 회전축을 중심으로 브릿지 형상으로 고정 설치되며, 회전축과 대응되는 중심면에는 접지팁이 돌출 형성된 탄성판과; 그 일단이 드럼 베이스의 일측면에 고정 설치되고, 그 타단이 헤드드럼의 회전축을 향해 연장 형성되어 탄성판의 접지팁과 접촉되는 접지 브라켓;을 포함하여 된 것으로서, 노이즈 및 지터에 의한 화면의 열화를 방지할 수 있게 된다.According to the present invention, there is provided a head drum comprising: an elastic plate fixedly installed in a bridge shape around a rotation axis of a head drum, the elastic plate having a ground tip protruding from a central surface corresponding to the rotation axis; And a ground bracket having one end fixed to one side of the drum base and the other end extending toward the rotation axis of the head drum and contacting the grounding tip of the elastic plate. The deterioration of the screen due to noise and jitter Can be prevented.

또한 그 부품수가 대폭적으로 감소시킬 수 있는 것이어서, 단가절감 및 작업성의 향상을 도모할 수 있으며, 특히 접지팁과 회전축의 중심을 일치시키기가 용히아여, 이 접지팁과 브라켓간의 마찰접촉에 의한 노이즈의 원인을 미연에 방지할 수 있게 된다.In particular, the center of the grounding tip and the rotating shaft can be made to coincide with each other, and the noise due to the frictional contact between the grounding tip and the bracket can be reduced, It is possible to prevent the cause of the accident.
