おける対物レンズの角度調整機構。 The adjustment table that supports the objective lens of the optical pickup is supported at multiple points on the chassis so that the distance can be adjusted using adjustment screws, and between the adjustment table and the chassis, the adjustment table is supported at an intermediate position between the adjustment screws. The adjustment table is provided with a support part that serves as a fulcrum when the adjustment table is adjusted in inclination according to changes in the amount of tightening of each adjustment screw, and the adjustment table is provided with an elastic support when the adjustment screw is tightened. A mechanism for adjusting the angle of an objective lens in an optical pickup, comprising an elastically deformable portion having a smaller width than other portions so as to be deformable.
