Detection switches (SW1, SW2) for detecting the position of the pickup unit, an optical sensor (17) installed on the pickup base (15) for detecting the presence or absence of a disk, and a light emitting diode (17-) of the optical sensor (17). 1) an optical sensor driver 18 for turning on and off, a detection signal amplifier 19 for amplifying a signal detected by the light receiving diodes 17-2, 27-3 of the optical sensor 17, and The light emitting diode 17-1 is turned on through the comparator 20 for supplying the amplified detection signal to the microcomputer 21 as disk presence detection information by comparing the amplified detection signal with a predetermined reference level. Or off and from the sensing switches SW1 and SW2 and the comparator 20 output information. A disc discrimination apparatus of a multi-disc player composed of a microcomputer (21) for discriminating the type of a disc. 픽업베이스(15)를 트레이 외주로 이동시킨 상태에서 광센서(17)를 구동시켜 디스크 유무의 감지여부를 판별하는 제1과정과, 판별결과 디스크가 감지되면 현재 디스크 트레이(4)에 장착된 디스크를 30㎝ 디스크로 판별하고 디스크가 감지되지 않으면 픽업베이스(15)를 트레이 내주로 이동시켜 감지스위치(SW1,SW2)를 통한 20㎝ 디스크 위치 도달여부를 판별하는 제2과정과, 판별결과 20㎝ 디스크 위치에 도달하였으면 그 위치에서 광센서(17)로 디스크가 감지되는가를 판별하여 감지되면 현재 디스크 트레이(4)에 장착된 디스크를 20㎝ 디스크로 판별하고 디스크가 감지되지 않으면 픽업베이스(15)를 내주로 이동시켜 감지스위치(SW1,SW2)를 통한 12㎝ 디스크 위치 도달여부를 판별하는 제3과정과, 판별결과 12㎝ 디스크 위치에 도달하였으면 그 위치에서 광센서(17)로 디스크가 감지되는가를 판별하여 감지되면 현재 디스크 트레이(4)에 장착된 디스크를 12㎝ 디스크로 판별하고 디스크가 감지되지 않으면 디스크 트레이(4)에 디스크가 없는 경우로 판별하는 제4과정으로 이루어진 멀티 디스크 플레이의 디스크 판별방법.The first process of determining whether the disk is detected by driving the optical sensor 17 while the pickup base 15 is moved to the outer periphery of the tray, and when the disc is detected as a result of the determination, the disc currently mounted in the disc tray 4 If the disc is not detected and the disc is not detected, the second process of determining whether the 20cm disc position is reached by detecting the switches SW1 and SW2 by moving the pickup base 15 to the inner circumference of the tray, and the determination result is 20cm If the disk position is reached, the optical sensor 17 determines whether the disk is detected at that position. If the disk is detected, the disk currently mounted on the disk tray 4 is determined as a 20 cm disk. If the disk is not detected, the pickup base 15 is detected. And the third step of determining whether the 12 cm disk position is reached by detecting switches SW1 and SW2 by moving the inner circumference, and if the 12 cm disk position is reached as a result of the determination, the light sensor 17 is moved from the position. If the disk is detected by detecting whether the disk is currently detected, the disk currently mounted in the disc tray 4 is determined to be 12 cm, and if the disk is not detected, the fourth process of determining that there is no disk in the disk tray 4 Disc determination method of disc play. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
