DEVICE FOR FIXING REFLECTIVE MIRROR OF OPTICAL PICKUP

摘要

PURPOSE: A device for fixing a reflective mirror of an optical pickup is provided to install the reflective mirror formed in curvature independently on a cover case of an optical pickup body, not integrally with an optical pickup driving part, so as to prevent light beam from deviating from a reflective area within an allowable range. CONSTITUTION: A light source(103) generates light beam(1000) to a driving part for the recording and reproduction of an optical disk in an upper and a lower cover cases(101,102). An objective lens(105) scans the light beam from the light source on a recording surface of the optical disk. A reflective mirror(110) refracts the light beam from the light source to scan the refracted light beam to the optical disk through the objective lens. The objective lens is configured by being separated from the driving part of an optical pickup optical system. And a reflective mirror fixing holder(111) couples with the reflective mirror on an internal of the upper cover case to separate the reflective mirror, and fixes and supports the reflective mirror.
