Abstract

본 발명은 광픽업엑츄에이터의 대물렌즈틸트조정장치에 관한 것으로, 광픽업엑츄에이터가 설치되는 픽업베이스의 상면 일측에 고정설치되며, 4모서리면에서 서스펜션와이어 끼움공이 형성되고, 바깥쪽면 중심부에는 반구형의 조정안내부가 일체로 돌설된 형태의 제1조정플레이트와, 상기 제1조정플레이트와 동일한 크기를 가지며 안쪽면 중심부에 제1조정플레이트상의 조정안내부가 끼워지는 반구형의 조정안내홈이 형성되고, 제1조정플레이트에서와 같은 위치에는 서스펜션와이어끼움공이 형성되는 한편, 바깥쪽면 중심에는 조정볼트끼움 홈이 형성된 제2조정플레이트와, 외부로부터 상기 제2조정플레이트상의 조정볼트끼움홈에 끼워진 상태에서 그 제2조정플레이트를 습동시켜 위치조정시켜주는 조정볼트로 구성하므로써 서스펜션의 움직임을 이용한 대물렌즈홀더의 조정을 통하여 대물렌즈이 틸트조정이 이루어지도록 하여 픽업베이스와 요크플레이트의 구조를 복잡하게 하지 않고도 간단한 동작에 의해 대물렌즈의 틸트조정이 이루어질 수 있도록 한 것이다.The present invention relates to an objective lens tilt adjusting device for an optical pickup actuator, which is fixedly installed on one side of an upper surface of a pickup base on which an optical pickup actuator is installed, and a suspension wire fitting hole is formed at four corners, and a hemispherical adjustment is provided at the center of the outer surface. The first adjustment plate of the form in which the guide part is integrally formed, and the hemispherical adjustment guide groove which has the same size as the said 1st adjustment plate, and which the adjustment guide part on a 1st adjustment plate fits in the center of an inner surface is formed, The 1st adjustment A suspension wire fitting hole is formed at the same position as that of the plate, while a second adjustment plate having an adjustment bolt fitting groove is formed at the center of the outer surface thereof, and the second adjustment in the state of being fitted into the adjustment bolt fitting groove on the second adjustment plate from the outside. The suspension bolt can be moved to adjust the position of the suspension. By adjusting the objective lens holder used, the objective lens is tilted so that the tilt of the objective lens can be made by simple operation without complicating the structure of the pickup base and the yoke plate.
