Abstract

본 발명은 레이져 디스크 플레이어의 디스크 판별장치에 관한 것으로, 재생하고자 하는 디스크가 LD인가 CD인가를 판별하는 기본적인 기능외에 상기 LD와 CD가 겹쳐져 있는가를 판별하는 부가적인 기능을 함께 수행할 수 있도록 구조를 변경하여 사용자의 부주의로 인해 디스크가 손상되거나 기기가 파손되는 것을 미연에 방지한 것이다. 이를 위해 본 발명은 클램프샤시(1)의 일측에 설치되어 플레이시 트레이에 의해 기기 내부로 안착된 디스크(3)를 감지하는 제1 감지센서(2)와, 하부 클램핑 수단을 구성하는 턴테이블(6)에 설치되어 플레이시 CD클램프(8)를 감지하는 제2감지센서(12)와, 상기 제1 감지센서(2)와 제2 감지센서(12)를 받아 디스크(3)의 종류 및 디스크의 겹침을 판별하는 마이콤(4)으로 구성하여서 된 것이다.The present invention relates to a disc discrimination apparatus of a laser disc player, and in addition to the basic function of discriminating whether a disc to be played is an LD or a CD, an additional function of determining whether the LD and the CD overlap with each other is modified. This prevents the user from inadvertently damaging the disk or damaging the device. To this end, the present invention is installed on one side of the clamp chassis 1, the first detection sensor (2) for detecting the disc (3) seated into the device by the tray during play, and turntable (6) constituting the lower clamping means And a second detection sensor 12 that detects the CD clamp 8 during play, the first detection sensor 2 and the second detection sensor 12, and the type of the disk 3 and the type of the disk. It consists of the microcomputer 4 which distinguishes overlap.
