Description

다중 디스크마가진의 디스크 플레이어에서 디스크 유무판별 처리시스템Disc presence / absence processing system in multi-margin disc player

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본발명에 의한 디스크 유무 판별시스템의 개략도,1 is a schematic diagram of a disk presence determination system according to the present invention,

제2도는 제1도에서 다중디스크마가진과 디스크유무 검출기 및 시스템 마이크로프로세서의 관련두성도,2 is an associated head diagram of a multiple disk margin and a disk presence detector and a system microprocessor in FIG.

제3도는 제1도의 마이크로프로세서에 내장된 디스크유무 판별처리 프로그램의 참고도.3 is a reference diagram of a disk presence discrimination processing program built in the microprocessor of FIG.

Claims (1)

복수의 디스크와 디스크 트레이(8)를 포함한 다중마가진(7)과, 디스크 위치로 찾아가는 업다운모터(5), 디스크 트레이(8)를 이동시키는 로딩모터(4) 및, 시스템 마이크로 프로세서(1)등을 포함한 디스크 플레어에 있어서, 상기 다중마가진(7)에는 디스크 트레이(8)에 탑재된 디스크의 유무를 탑지하는 광센서(LD,PD)를 두고, 이 광센서(LD,PD)는 마이크로 프로세서(1)에 의해 점소등 제어되어지며, 상기 마이크로 프로세서(1)에는 정상 플레이시와 랜덤 플레이시에 각기 다중마가진(7)으로부터 인출되는 디스크트레이(8)에 탑재된 디스크 유무를 광센서(LD,PD)로 탐지하여 디스크가 있을때는 통상의 로딩 과정으로 넘어가고 디스크가 존재하지 않을때는 디스크 트레이(8)를 소정 인출시점에서 자동복귀 시키고 다음 스텝으로 넘어가는 일련의 처리과정을 가진 노멀시의 NDS와 랜덤시의 RDS서브루틴을 포함한 디스크 유무판별 처리프로그램(DSP)이 구비되어진 구성을 특징으로 하는 다중디스크 마가진의 디스크 플레이어에서 디스크유무 판별처리시스템.Multiple margins (7) including a plurality of disks and disk trays (8), an up-down motor (5) for moving to a disk position, a loading motor (4) for moving the disk trays (8), a system microprocessor (1), and the like. In the disk flare including, the multi-margin (7) is provided with optical sensors (LD, PD) to support the presence or absence of the disk mounted on the disk tray (8), the optical sensors (LD, PD) is a microprocessor ( 1) is turned on and off, and in the microprocessor 1, the presence or absence of the disc mounted in the disc tray 8 drawn out from the multi-margin 7 during normal play and random play, respectively, is detected by the optical sensor LD ,. If a disk is detected and the disk is present, the process proceeds to the normal loading process, and if the disk does not exist, the disk tray 8 is automatically returned at a predetermined ejection time point, and then the normal process is performed. A disk presence discrimination processing system in a disk player having a multiple disk margin, characterized by a configuration including a disk presence and absence processing program (DSP) including an NDS and a random RDS subroutine. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
