  • Publication number: 20130276003
    Abstract: A disadvantage is reduced in which a front panel of an optical disc unit tilts by a clearance (rattle) between the components and contacts with a body of a PC incorporating the unit to cause malfunction of insertion and ejection of discs. A disc tray is provided to move relative to rail guides attached to a bottom case of the optical disc unit via rails. The disc tray and rail guides have projection portions to contact with each other with stress. As a result, the clearance is reduced and the disadvantage due to the malfunction is reduced. The contact of the projection portions is close to point contact. The number of the contact positions is three or four. Support portions are provided to the rail guides to generate the stress.
