。[Claims for Utility Model Registration] (1) A spindle motor attached to a motor base, a turntable supported by the spindle shaft, and light linearly sent back and forth in the radial direction of a disk loaded on the turntable. In a CD player or the like equipped with a pickup, the motor base is supported so as to be swingable about respective fulcrums in a radial direction parallel to the linear feed direction and in a tangential direction perpendicular to the radial direction, and the motor base is A radial adjustment screw and a tangential adjustment screw are provided on the base to swing in the radial direction and tangential direction, respectively, about the fulcrum, and the center axis of the spindle motor is adjusted by the screw rotation of the two adjustment screws. An optical axis adjustment device for an optical pickup, characterized in that the tilt can be adjusted with respect to the optical axis. (2) Claim (1) characterized in that the motor base is elastically supported by a spring at the swinging fulcrum in the radial direction or tangential direction.
Optical axis adjustment device for the optical pickup described above. (3) Claim (1) characterized in that the motor base is supported by a pivot bearing structure at the swing fulcrum in the radial direction or tangential direction.
) Optical axis adjustment device for the optical pickup described in ). (4) The verticality of the turntable surface supported by the spindle shaft of the spindle motor is adjusted in inclination with respect to the optical axis by screw rotation of the two adjustment screws. (1) An optical axis adjustment device for the optical pickup described in (1). (5) The motor base is supported by a screw at the pivot point in the radial direction or the tangential direction, and the screw part is biased by a spring to maintain elasticity.
The optical axis adjustment device for the optical pickup described in (1) or (2).
