Optical disk drive assembly that is rotatable with respect to a computer casing

A computer comprising:

• a main body casing accommodating a plurality of hardware components and having an entrance opening on a first side thereof;
• an optical disk drive assembly coupled to the main body casing to rotate relative to the main body casing, the optical disk drive assembly including a supporting bracket;
• a hinge unit provided on a side of the entrance opening of the main body casing, and supporting the optical disk drive assembly to enable the optical disk drive assembly to rotate between an accommodated position where the optical disk drive assembly is accommodated in the main body casing and an ejected position where the optical disk drive assembly is ejected out of the main body casing through the entrance opening;
• wherein the hinge unit comprises first and second hinges being spaced from each other with a predetermined distance along a longitudinal direction on the side of the entrance opening, the first hinge comprising:
• a hinge protrusion formed on a bottom surface of the supporting bracket;
• and
• a pair of main body hinge holes provided on the side of the entrance opening of the main body casing, and rotatably accommodating the hinge protrusion.

• and
• a hinge unit provided on a side of the entrance opening of the main body casing, and supporting the optical disk drive assembly to enable the optical disk drive assembly to rotate between an accommodated position where the optical disk drive assembly is accommodated in the main body casing and an ejected position where the optical disk drive assembly is ejected out of the main body casing through the entrance opening;
• and
• a lock for locking or unlocking the optical disk drive assembly relative to the main body casing in the accommodated position;
• wherein the lock comprises:
• a locking holder provided on one of the main body casing and the optical disk drive assembly;
• and
• a latch member provided on the other one of the main body casing and the optical disk drive assembly, comprising a locking part capable of engaging with the locking holder, and rotating between a locking position where the locking part stops rotation of the optical disk drive assembly by being engaged with the locking holder and an unlocking position where the rotation of the optical disk drive assembly is allowed as the locking part is disengaged from the locking holder;
• wherein the latch member is installed on a side of the supporting bracket;
• and
• wherein the locking holder comprises a locking groove formed through the latch locking part installed on a side of the main body casing opposite to the entrance opening.
