Abstract

본 발명은 복수 종류의 디스크가 장착되는 트레이를 갖추어 그 트레이(12)상에 장착된 디스크로부터 정보를 독취하여 재생하도록 된 멀티디스크플레이어에서 그 트레이(12)상에 장착되는 디스크의 종류를 자동으로 판별하여 재생이 이루어지도록 하기 위한 멀티디스크플레이어에서의 디스크판별장치에 관한 것으로, 상기 트레이(12)상에 소정 위치에 설치되어 그 트레이(12)상에 안착되는 디스크의 중량을 전압으로 검지하는 디스크중량검출수단(10)과, 상기 디스크중량검출수단(10)에서 출력되는 전압을 디지탈변환하는 아날로그-디지탈변환기(20), 상기 디지탈변환된 디스크의 중량의 전압신호를 기준전압레벨과 비교하여 디스크의 종류를 판별함과 더불어 그 판별된 디스크의 억세스를 위한 재생재어신호를 출력하여 디스크억세스를 위한 재생메카니즘(40)을 구동하는 디스크판정 및 제어부(30) 및 상기 복수 종류의 디스크의 중량에 대한 기준치가 미리 저장된 기준레벨기억부(40)를 갖추어 디스크의 종류판별 및 재생이 자동으로 이루어지도록 구성되고, 상기 디스크중량검출수단(10)은 상기 트레이(12)의 내주측상에 설치되어 디스크의 중량을 검출하는 중량센서로 구성된 것이다.According to the present invention, a multi-disc player having a tray on which a plurality of discs are mounted to read and reproduce information from the disc mounted on the tray 12 automatically determines the type of the disc to be mounted on the tray 12. A disc discrimination apparatus in a multi-disc player for discriminating and reproducing, wherein the disc is provided at a predetermined position on the tray 12 and detects the weight of the disc seated on the tray 12 as a voltage. The weight detection means 10, the analog-to-digital converter 20 for digitally converting the voltage output from the disk weight detection means 10, and the voltage signal of the weight of the digitally converted disk are compared with a reference voltage level. The playback mechanism for disc access by determining the type of the disc and outputting the playback control signal for access to the disc A disc determination and control unit 30 for driving 40 and a reference level memory unit 40, in which reference values for the weights of the plurality of discs are stored in advance, are configured to automatically determine the disc type and play the disc. The disk weight detecting means 10 is configured on the inner circumferential side of the tray 12 and constitutes a weight sensor for detecting the weight of the disk.
