Abstract

본 발명은 광 디스크 재생장치의 전원 오프시 디스크 및 세트 보호장치 및 방법에 관한 것으로, 외부로부터 전송되는 상용 전원을 공급하는 제1 전원부(10)와, 일정한 직류 전원을 발생하는 제2 전원부(30)와, 제1 및 제2 전원부(10, 30)로부터 제공되는 전원을 선택하는 전원 선택부(40)와, 전원 선택부(40)에서 선택되어 제공되는 제1 또는 제2 전원부(10, 30)의 전원에 의해 구동되는 로딩 모터(50)와, 제1 전원부(10)의 전원 차단시 전원 선택부(40)로부터 전원 차단 신호를 수신하여 로딩 모터(50)에 제2 전원부(30)의 출력 전원이 로딩 모터(50)에 제공되도록 전원 선택부(40)를 제어하는 마이컴(50)을 포함하고 구성되어, 돌발적으로 전원이 오프될 때 디스크가 처킹부를 이탈하므로써 발생할 수 있는 디스크의 손상 및 타 부품의 고장을 방지할 수가 있다.The present invention relates to a disc and a set protection device and method when the optical disc player is powered off. The present invention relates to a first power supply unit (10) for supplying commercial power transmitted from the outside, and a second power supply unit (30) for generating a constant DC power supply. ), A power selector 40 for selecting the power provided from the first and second power supply units 10 and 30, and a first or second power supply unit 10 and 30 selected and provided by the power selector 40. When the power supply of the loading motor 50 and the first power supply unit 10 shuts off, the power supply signal is received from the power supply selection unit 40 to receive the loading motor 50 of the second power supply unit 30. And includes a microcomputer 50 that controls the power selector 40 so that the output power is provided to the loading motor 50, so that the disk may be damaged by leaving the chucking part when the power is unexpectedly turned off. Failure of other parts can be prevented.
