Abstract

본 발명은 광픽업장치에 관한 것으로, 특히 광픽업 어셈블리의 엑튜에이터구조를 변경하여 광픽업의 광축조정을 정확하게 할 수 있는 광픽업장치를 제공하는 것을 목적으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical pickup apparatus, and more particularly, to an optical pickup apparatus capable of precisely adjusting an optical axis of an optical pickup by changing an actuator structure of the optical pickup assembly.

상기의 목적을 달성하기 위한 본 발명에 따른 광픽업장치는 통공(20a)를 갖는 반구형면이 형성되어 있고 통공(20a)하부에 콜리메이터렌즈(24)가 설치된 베이스(20)와, 수직관통홀(10a)이 형성되어 있고 정호가한 광축 조정을 위하여 상기 베이스(20)의 반구형면에 밀착지지 되도록 반구형으로 형성되어 요크(18)에 장착되는 반구형 지지부재(10)를 포함하는 것을 본 발명의 요지로 하고 있다.Optical pickup device according to the present invention for achieving the above object is formed with a hemispherical surface having a through hole (20a) and the base 20, the collimator lens 24 is installed below the through hole (20a), and a vertical through hole ( The subject matter of the present invention includes a hemispherical support member 10 which is formed in a hemispherical shape so as to be closely attached to the hemispherical surface of the base 20 and is mounted to the yoke 18 for a precise optical axis adjustment. I am doing it.
