Abstract

본 발명은 헤드럼의 헤드창 검출장치를 개시한다.The present invention discloses a head window detection device for a head rum.

본 발명은, 구동모터와; 구동모터에 의해 회전 구동되며, 상부드럼이 안착되는 안착보스가 마련된 지그와; 그 단부가 지그의 안착보스에 안착된 상부드럼의 하부와 인접되도록 위치되며, 상부드럼의 하부 가장자리면과 대응되는 위치에는 경사판이 고정 설치된 지지 플레이트와; 지지 플레이트의 일측면에 고정 설치되는 커버에 내장 설치되며, 수, 발광소자를 갖는 센서부와; 경사판상에 고정 설치되어 센서부의 발광소자에 의해 주사된 빔을 상부드럼의 하부 가장자리면으로 반사시키고, 이 하부 가장자리면으로부터 반사된 빔을 수광소자로 반사시키는 반사미러를 포함하여 된 것으로서, 통상의 헤드 드럼 뿐만 아니라 경질탄소막이 코팅된 헤드드럼일지라도, 경질탄소막이 코팅되지 않은 상부드럼이 하부 가장자리면을 통해 헤드창을 검출하도록 된 것이어서, 헤드창의 검출을 용이하게 행할 수 있는 효과가 있다.The present invention, the drive motor; A jig rotatably driven by a drive motor and provided with a seating boss on which an upper drum is mounted; A support plate having an end thereof positioned adjacent to a lower portion of an upper drum seated on a seating boss of the jig, and having an inclined plate fixed at a position corresponding to a lower edge surface of the upper drum; A sensor unit installed in a cover fixed to one side of the support plate and having a male and a light emitting element; It includes a reflecting mirror fixedly mounted on the inclined plate to reflect the beam scanned by the light emitting element of the sensor unit to the lower edge surface of the upper drum, and reflects the beam reflected from the lower edge surface to the light receiving element. Even if the head drum is coated with the hard carbon film as well as the head drum, the upper drum without the hard carbon film is designed to detect the head window through the lower edge surface, so that the head window can be easily detected.
