Disk device equipped with a skew-adjusting mechanism for an optical pickup
First Claim
1. A disk device equipped with a skew-adjusting mechanism for an optical pickup, comprising a traverse unit having a chassis, two guide rails arranged in parallel with each other on the chassis, a turntable to mount a disk thereon, and an optical pickup to be driven to move along the guide rails irradiating a recording surface of the disk with a laser beam to effect recording and reproduction, wherein the traverse unit further having a fixed support member for supporting one end of at least one of the guide rails, and a movable support member made of a resin for supporting the other end thereof, said movable support member being secured to the chassis integrally therewith, a threaded hole being formed penetrating through the chassis and the movable support member, a skew-adjusting screw being screwed with said threaded hole in a manner that an end of the skew-adjusting screw protrudes upward beyond the movable support member, and the guide rail being urged toward the skew-adjusting screw.

Abstract
A disk device equipped with a skew-adjusting mechanism for an optical pickup, including a traverse unit having a chassis, two guide rails arranged in parallel with each other on the chassis, a turntable to mount a disk thereon, and an optical pickup to be driven to move along the guide rails irradiating a recording surface of the disk with a laser beam to effect recording and reproduction. To adjust a guide rail correctly and finely enabling the optical pickup to move maintaining a predetermined distance at all times with respect to the recording surface of the disk to accomplish correct recording and reproduction, the traverse unit further has a fixed support member for supporting one end of at least one of the guide rails, and a movable support member made of a resin for supporting the other end thereof, said movable support member being secured to the chassis integrally therewith, a threaded hole being formed penetrating through the chassis and the movable support member, a skew-adjusting screw being screwed with said threaded hole in a manner that an end of the skew-adjusting screw protrudes upward beyond the movable support member, and the guide rail being urged toward the skew-adjusting screw.
