Abstract

본 발명은 조립공정을 더욱 간단하게 하면서 박형화를 동시에 달성하기 위한 광픽업장치에 관한 것이다.The present invention relates to an optical pickup apparatus for achieving a thinning at the same time while simplifying the assembly process.

본 발명에 의한 광픽업장치는, 비임을 발살하기위한 광원; 상기 광원에서의 비임을 광기록매체에 집광시키기 위한 렌즈장치; 광디스크로부터 반사된 비임을 검출하기 위한 광검출기; 상기 광경로상에 위치하고, 광원에서의 비임을 평행광으로 변환하기 위한 시준렌즈와, 반사된 비임을 광검출기로 반사하기위한 비임 스플리터와, 비임스플리터에서의 광을 집광하기 위한 센서렌즈가 일체화된 렌즈어셈블리로 구성된다. 렌즈어셈블리는 비임 스플리터와, 시준렌즈및 센서렌즈를 각각 접착하는것으로 일체화시키고 있다.An optical pickup apparatus according to the present invention comprises a light source for emitting a beam; A lens device for condensing a beam from the light source onto an optical recording medium; A photodetector for detecting the beam reflected from the optical disc; Located on the optical path, a collimating lens for converting the beam from the light source to parallel light, a beam splitter for reflecting the reflected beam to the photodetector, and a sensor lens for condensing light from the beam splitter It consists of a lens assembly. The lens assembly is integrated by bonding a beam splitter, a collimating lens and a sensor lens, respectively.
