Abstract

디스크 플레이어에 있어서, 디스크와 픽업 사이의 기울기를 최적의 상태로 조정하는 픽업 기울기 조정 장치에 관해 개시한다. 본원의 픽업 기울기 조정 장치는 데크에 픽업을 관통지지하는 적어도 하나의 가이드 샤프트가 갖춰지고, 픽업이 그 가이드 샤프를 따라 디스크의 반경방향으로 이동될 수 있게 된 디스크 플레이어의 픽업 기울기 조정 장치에 있어서, 데크에 수직방향으로 관통된 나사공 및 장공부가 형성되고, 나사공에 체결되어 상기 가이드 샤프트의 일단을 수직방향으로 밀어올리는 스크류 및 일단이 장공부에 탄성바이어스되게 삽입되며, 타단이 스크류와 대향되는 위치에서 가이드 샤프트를 수직방향으로 지지하는 탄성부재를 포함하는 것을 특징으로 한다. 본원의 기울기 조정 장치를 채용함으로써, 턴테이블상에 회전되는 디스크와의 기울기를 정밀하게 유지시킬 수 있게 되어, 포커싱 및 트래킹 서보의 신뢰성을 향상시킴으로써, 결과적으로 디스크 플레이어의 재생 정도를 향상시킬 수 있는 잇점이 있다.In a disk player, a pickup tilt adjusting device for adjusting an inclination between a disk and a pickup to an optimum state is described. The pickup tilt adjustment device of the present invention is characterized in that the pickup tilt adjustment device of the disc player is provided with at least one guide shaft for supporting the pickup to penetrate the deck and the pickup can be moved in the radial direction of the disc along the guide sharpness, And a screw for one end of the guide shaft to be vertically pushed and inserted into the elongated hole so as to be elastically biased, and the other end of the screw is inserted in a direction opposite to the screw And an elastic member for supporting the guide shaft in a vertical direction at a position where the guide shaft is supported. By employing the tilt adjusting device of the present invention, it is possible to accurately maintain the inclination with respect to the rotating disk on the turntable, thereby improving the reliability of the focusing and tracking servo, and as a result, the advantage .
