Abstract

본 발명은 디스크 플레이어의 디스크 클램핑장치에 관한 것이다.The present invention relates to a disk clamping apparatus for a disk player.

본 발명에 따른 디스크 플레이어의 디스크 클램핑장치는, 턴테이블과 함께 디스크를 압압하는 압압부재가 스프링부재에 이해 턴테이블 측으로 탄성 바이어스되도록 구성되어 있으므로, 디스크를 확실하게 클램핑하여 디스크의 회전시 턴테이블에 대해 미끄러지는 것을 방지할 수 있을 뿐만 아니라, 클램핑 해제시에 소음의 발생을 효과적으로 억제할 수 있다.In the disk clamping apparatus for a disk player according to the present invention, since the pressing member for pressing the disk together with the turntable is elastically biased toward the turntable by the spring member, the disk is clamped reliably, It is possible to effectively prevent the occurrence of noise at the time of releasing the clamping.
