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 γ o>Tan−1 (μ/Cos αn) where γ o is a lead, μ is friction coefficient, and α n is normal pressure angle. The worm has a lead angle γ o greater than 15°.
Claims7
A disk-loading apparatus in which a main chassis supports a tray that carries a disk thereon and slides between a disk-discharging position and a disk-loading position, the apparatus comprising:
- a motor mounted on the main chassis and having a rotating shaft;
- a worm formed on the rotating shaft;
- a drive gear rotatably mounted on the main chassis, said drive gear having a first gear and a second gear, the second gear being in mesh with said worm;
- and
- a rack formed in the tray and in mesh with the first gear so that when the motor rotates to move the tray between the disk-discharging position and the disk-loading position.
