Abstract

이 발명은 디스크 플레이어의 이중 클램프 장치에 관한 것으로서, 턴테이블의 상면에 안착되는 양면 디스크의 중심을 보정하기 위해 디스크의 상면에 척킹되는 클램프를 이중 클램프로 하여 데크내에 상,하로 이송되게 장착하는 것이다. 따라서, 디스크의 양면에 신호를 기록하거나 재생할 때, 광픽업 장치에서 주사되는 빔의 정점이 일치되게 이중 클램프로 디스크의 중심을 보정하고, 디스크의 회전 및 정지시에 슬립이 방지되어 정상적인 동작을 수행할 수 있다.The present invention relates to a double clamp device of a disc player, in order to correct the center of a double-sided disk seated on the upper surface of the turntable, the clamp chucked to the upper surface of the disk as a double clamp is mounted to be transported up and down in the deck. Therefore, when recording or reproducing signals on both sides of the disc, the center of the disc is corrected by the double clamp to match the vertices of the beams scanned by the optical pickup device, and slips are prevented when the disc is rotated and stopped to perform normal operation. can do.
