Abstract

디스크 클램핑 장치를 개시한다. 본 발명은 스핀들 모타의 회전축에 고정되어 디스크 플레이어 본체 내에 승강 가능하게 설치되며 그 중앙부에는 디스크의 중앙에 형성된 관통홀이 끼워지는 돌출부가 형성된 턴테이블과, 디스크 플레이어의 본체에 승강가능하도록 결합되며 상기 턴테이블의 상방에 위치하여 디스크를 압압하는 풀리를 구비하여 된 디스크 클랭핑 장치에 관한 것으로, 상기 폴리는 가장자리에서 중앙으로 갈수록 점진적으로 높이가 높아지는 본체와; 상기 본체의 가장자리부와 중앙부를 잇는 선상에서 상기 본체의 상면에 대해 그 본체의 회전방향과 반대방향으로 경사지게 돌출되며 소정각도 간격으로 이격된 복수의 리브를 포함하여 된 것에 그 특징이 있다. 본 발명을 채용함으로써, 공기압을 이용하여 손쉽게 디스크를 클램핑할 수 있는 효과가 있다.Disclosed is a disk clamping device. The present invention relates to a spindle motor which is fixed to a rotary shaft of a spindle motor so as to be able to move up and down within a disc player body and has a protruding portion formed at the center thereof with a through hole formed at the center of the disc, The present invention relates to a disc clamping apparatus having a pulley which is positioned above a disc and which presses the disc, wherein the disc has a height gradually increasing from the edge to the center; And a plurality of ribs projecting obliquely in a direction opposite to a rotation direction of the main body with respect to an upper surface of the main body on a line connecting the edge portion and the center portion of the main body and spaced apart at predetermined angular intervals. By employing the present invention, it is possible to easily clamp the disk by using air pressure.
