Abstract

디스크 플레이어의 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 승강 가능하도록 결합되며 상기 턴테이블의 상방에 위치하여 디스크를 압압하는 풀리를 구비하여 된 디스크 플레이어의 디스크 클램핑 장치에 있어서, 상기 턴테이블의 돌출부는 그 선단이 탄력적으로 벌어질 수 있는 복수개의 탄성편을 구비하고, 상기 풀리는 그 하면의 중앙부에 압압돌기가 형성되어 상기 복수의 탄성편 사이로 끼워지며 그 탄성편이 벌어지면서 디스크의 관통홀 내면을 압압함으로써 디스크를 지지하는 것을 특징으로 한다. 본 고안을 채용함으로서, 디스크 센터링 및 클램핑이 용이한 효과가 있다.Disclosed is a disk clamping device for a disk player. The present invention relates to a spindle motor comprising a turntable fixed to a rotary shaft of a spindle motor and vertically installed in a disc player body and having a protrusion formed at a central portion thereof with a through hole formed at the center of the disc, Wherein a protrusion of the turntable has a plurality of resilient pieces whose distal ends can be elastically opened, and the pulleys are provided on the bottom surface of the disk And a pressing protrusion is formed at a central portion thereof to be sandwiched between the plurality of elastic pieces and the elastic piece is spread to press the inner surface of the through hole of the disc to support the disc. By adopting this design, disk centering and clamping are easy.
