  • Publication number: 20060294529
    Abstract: A recording and reproducing apparatus includes a tray disposed within an outer casing and movable along a tray moving direction between retracted and extended positions. A positioning structure includes a locking member fixed on the outer casing, and a support member for immobilizing the locking member with respect to the outer casing in such a manner that the locking member extends upwardly into the outer casing to prevent movement of the tray with respect to the outer casing. A protrusion portion of the outer casing surrounding the locking member and extending in the moving direction defines the support member.

  • Publication number: 20050010937
    Abstract: A locking member for use in an optical disk drive includes a base, a tubular projection, and an enlarged portion. The base and the tubular projection are integrally formed with the enlarged portion. A hole formed in the chassis of the optical disk drive is sized to receive the locking member, such that the locking member extends through the hole. The locking member can be fixed on the chassis by riveting, and can absorb a large impact or shock. Alternatively, screw threads can be integrally formed on the hole and the enlarged portion. The locking member can be threaded through and engage with the hole of the chassis to absorb the impact or shock without breakage or failure.
