Optical disc fixing device and optical disc drive using same

An optical disc fixing device to fix an optical disc, the optical disc defining a circular mounting hole at the center portion, the optical disc fixing device comprising:

• a cylindrical clamping chassis having a shape substantially the same as the mounting hole of the optical disc and comprising a peripheral sidewall;
• two latching pieces assembled within the clamping chassis and located adjacent to the peripheral sidewall of the clamping chassis;
• a control member hinged on the clamping chassis enabling the two latching pieces to partially extend from the peripheral sidewall of the clamping chassis to hold the optical disc;
• and two elastic members assembled to the corresponding latching pieces to provide an elastic force to enable the two latching pieces to resume their original position when the control member is released.

An optical disc drive, comprising:

• an optical disc tray for bearing an optical disc comprising a central mounting hole;
• a turntable rotatably assembled to the optical disc carry tray for supporting the optical disc;
• an optical pickup assembled to the bearing tray and positioned adjacent to the turntable for recording or reproducing information on the optical disc;
• and
• an optical disc fixing device to fix the optical disc, the optical disc fixing device comprising:
• a cylindrical clamping chassis fixed on the turntable and having a shape substantially the same as the mounting hole of the optical disc, the clamping chassis comprising a top surface and an opposite bottom surface, the top surface defining a mounting groove and a mounting slot, the bottom surface defining two accommodating slots positioned adjacent to two sides of the mounting groove and communicating with the mounting groove, the mounting slot crossing with the mounting groove and located between the two accommodating slots, two ends of the mounting slot respectively communicate with the two accommodating slots, a distal end of the mounting groove defining two latching slots;
• two latching pieces assembled within the clamping chassis and located adjacent to the peripheral sidewall of the clamping chassis;
• a control member hinged on the clamping chassis enabling the two latching pieces to partially extend from the peripheral sidewall of the clamping chassis for holding the optical disc, the control member hinging on the mounting groove for biasing the two latching pieces, the control member comprising a base body, a resisting protrusion formed on the base body, and a latching portion formed at a distal end of the base body opposite to the hinged end, the base body hinged to one end of the mounting groove, and the resisting protrusion clamped between the two latching pieces to resist two corresponding latching pieces toward the peripheral sidewall, the latching portion latching with the two latching slots of the clamping chassis;
• and
• two elastic members respectively assembled to the two latching pieces providing an elastic force to enable the two latching pieces to return to original positions when the control member is released,
• wherein the two latching pieces together with the two elastic members are assembled within the two accommodating slots.
