Abstract

본 발명은 광디스크플레이어용 광픽업엑츄에이터의 서스펜션에 관한 것으로, 탄성률이 양호한 얇은 플레이트의 길이방향 중심으로부터 양쪽으로 일정거리 떨어진 지점에 절곡부를 형성한 다음, 각 절곡부사이의 부분을 대물렌즈홀더의 선단내면에 부착하여 트랙킹방향조정부재로 구성하고, 상기 각 절곡부로부터 연장되는 양단을 지지부재의 상하면에 부착하여 각절곡부와 양단사이의 부분을 포커싱방향조정부재로 구성하므로써 대물렌즈의 포커싱방향운동과 트랙킹방향운동이 운동방향이외의 방향으로 부터의 외란이 작용되더라도 두방향이 자유도에 의하여 정확히 수행될 수 있도록 하고, 내부구조를 단순화시킬 수 있도록 한 것이다.The present invention relates to a suspension of an optical pick-up actuator for an optical disc player, wherein a bent portion is formed at a predetermined distance to both sides from a longitudinal center of a thin plate having good elastic modulus, and then a portion between the bent portions is formed on the inner surface of the front end of the objective lens holder. It is attached to the tracking direction adjusting member, and both ends extending from the bent portions are attached to the upper and lower surfaces of the supporting member, and the portion between each bent portion and both ends is composed of the focusing direction adjusting member. Even if the tracking direction movement is disturbed from the direction other than the movement direction, the two directions can be accurately performed by the degree of freedom, and the internal structure can be simplified.
