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.
