본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 디스크플레이어의 광학 헤드 장치의 일예를 도시하는 외관 사시도.
제2도 및 제3도는 각각 제1도에 도시되는 예에 있어서 대물렌즈 구동 유니트 및 광 비임 발생. 검출 유니트를 도시하는 분해사시도.

Claims (1)

  1. 광 비임 발생부, 콜리미이터 렌즈 및 광 검출기가 소정의 위치에 설치되고, 상기 광 비임 발생부로부터의 광 비임을 상기 콜리미이터 렌즈로 향하게 함과 동시에, 상기 콜리미이터 렌즈를 통해서 입사하는 광 비임을 상기 광 검출기로 유도하는 비임 스트리터가 내장된 광 비임 발생. 검출 유니트와,
    대물렌즈를 유지함과 함께, 이 대물렌즈를 그 광축에 연하는 제1의 방향 및 이 제1의 방향과 직교하는 제2의 방향으로 변위시키는 대물렌즈 구동 유니트와,
    상기 콜리미이터 렌즈를 통과한 광 비임이 소정의 경로를 통해서 상기 대물렌즈에 입사시켜지는 상태로서, 상기 광 비임 발생. 검출 유니트와 대물렌즈 구동 유니트가 고정시켜지는 가동 베이스 부재를 구비하여 구성되는 디스크플레이어의 광학 헤드 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
