Claims

[Claims for Utility Model Registration] 1. A side part of the optical pick-up is supported so as to be able to slide in the direction along the recording surface of the disk with respect to a slide shaft, and one end of the slide shaft is arranged so that the optical pick-up is aligned with the recording surface of the disk. The other end of the slide shaft is supported in a sliding groove formed in the shaft support member so as to be able to slide in the direction of the rotation operation. ,
A roller provided on the optical pickup rolls on a guide plate extending in the direction of movement of the optical pickup, and the slide shaft and the guide plate determine the attitude of the optical pickup to face the disk recording surface, and the slide In an optical pickup equipped with a tilt drive mechanism that changes the rotation angle of the shaft, the shaft support member and the guide plate are integrally molded, and the two are fixed to the chassis. An optical pickup guide device featuring: 2. The side part of the optical pick-up is supported so that it can slide in the direction along the recording surface of the disk with respect to the slide shaft, and one end of the slide shaft is supported so that the optical pick-up can be rotated in the direction toward and away from the recording surface of the disk. The slide shaft is movably supported, and the other end of the slide shaft is supported so as to be slidable in the rotation direction within a sliding groove formed in the shaft support member, and
A roller provided on the optical pickup rolls on a guide plate extending in the direction of movement of the optical pickup, and the slide shaft and the guide plate determine the attitude of the optical pickup to face the disk recording surface, and the slide In an optical pickup equipped with a tilt drive mechanism that changes the rotation angle of the shaft, the shaft support member and the guide plate are fixed so that their relative positions can be adjusted.
