光ピツクアツプ装置。 A focus servo is used in an optical pickup device that is used to record information on an optical recording medium by irradiating the optical recording medium with a focused light beam in a focused spot shape, and to record information on the recording medium and reproduce recorded information. For optical members that require fine adjustment of the mounting position or angle, such as critical angle prisms used in A fitting hole for an adjustment driver is provided in which an eccentric pin that is inserted into the elongated hole is protruded, so that the mounting position or angle of the stand can be finely adjusted, and the screwdriver is inserted loosely through the through hole provided on the main body side. An optical pickup device comprising means for screwing a set screw into a screw hole formed in the base to fix it.
