Abstract

본 발명은 광학식 디스크 드라이브의 기록 및 재생 장치인 광 픽업(pick-up)장치의 대물렌즈 구동장치를 광학베이스에 조립시에 대물렌즈의 경사를 조정하는 장치로서, 광 픽업장치의 각 부품을 연결하는 고무홀더를 사용함으로써, 간단한 구성에 의해 두 방향의 경사 조정을 구현한 장치에 관한 것이다. 광 픽업장치의 각 부품을 연결하는 고무홀더를 대물렌즈의 경사조정용 장치로 사용함으로써; 경사조정을 위한 부가 부품이 필요 없으며, 광 픽업장치의 소형화가 가능하고, 조립 및 수정이 용이하며, 부품수를 줄임으로써 제품의 생산단가를 낮추는 효과가 있어서, 컴팩트 디스크나 시디-롬(CD-ROM) 등에서 광 픽업장치의 조립시에도 활용이 가능하므로 매우 유용하다.The present invention is an apparatus for adjusting the inclination of an objective lens when assembling an objective lens driving apparatus of an optical pick-up apparatus, which is a recording and reproducing apparatus of an optical disc drive, to an optical base, and connecting each component of the optical pickup apparatus. The present invention relates to a device that realizes inclination adjustment in two directions by a simple configuration. By using a rubber holder for connecting each part of the optical pickup device as a device for tilt adjustment of the objective lens; There is no need for additional parts for tilt adjustment, miniaturization of the optical pick-up device, easy assembly and modification, and the reduction of the number of parts reduces the production cost of the product. It is very useful because it can be utilized when assembling optical pickup device in ROM).
