ABSTRACT:
A main chassis supports a tray that carries a disk thereon and moves between a disk-discharging position and a disk-loading position. A motor is mounted on the main chassis and has a rotating shaft. A worm is formed on the rotating shaft. A drive gear rotatably is mounted on the main chassis and has a pinion gear and a worm wheel in mesh with the worm. The pinion gear is in mesh with a rack formed in the tray. The worm preferably satisfies a dimensional condition γo>Tan−1(μ/Cos αn) where γo is a lead, μ is friction coefficient, and αn is normal pressure angle. The worm has a lead angle γo greater than 15°. The rotating shaft extends in a direction at an angle with a plane in which the drive gear rotates.
