Claims

[Scope of utility model registration request]

(1) The player's hand includes a housing and a playing means for playing a disc provided in the housing, and the player's hand includes a supporting member and a guide shaft provided on the supporting member and extending in the radial direction of the disc. , a holding mechanism that holds an optical system including an objective lens and is guided by the guide shaft, and the optical axis of the irradiation light emitted from the optical system toward the disk recording surface intersects at right angles with the disk recording surface. and a tilt servo mechanism, the tilt servo mechanism being configured to swing the guide shaft from a reference position in a plane including a disk rotation axis.

(2) The tilt servo mechanism includes a support means provided on the support member to swingably support the guide shaft in a direction parallel to the disk rotation axis, and a support means extending substantially parallel to the disk rotation axis and supporting the guide shaft in a direction parallel to the disk rotation axis. a screw shaft that is screwed into the member and engages the swinging end of the guide shaft at one end; a gear fixed to the other end of the screw shaft; and a gear rotatably supported at the one end. A practical device characterized in that it comprises a transmission shaft provided with a worm that meshes with the gear, and a knob member fixedly attached to the other end of the transmission shaft (at least a part of which is exposed to the outside of the housing). An optical disc player according to claim 1 of patent registration.

(3) Utility model registration claim 1 or 2, characterized in that the guide shaft is returned to the reference position when a lid member provided on the housing is opened. Optical disc player as described.
