Clamping apparatus for clamping a disk in a disk drive

A clamping device of a disk drive comprising:

• a chassis;
• a driving source attached to the chassis to rotate a driving member;
• a clamping member to clamp a disk being ascended and descended by virtue of a rotation movement of the driving member;
• a clamping member ascending and descending unit to switch the rotation movement of the driving source to a vertical movement of the clamping member, to elastically support the disk on a turntable;
• and
• an elastic press member operatively connected to the driving member to push the clamping member towards the disk, wherein the elastic press member comprises:
• a circular body portion operatively connected with the driving member;
• a press plate coupled to the body portion and pressing the clamping member;
• and
• an elastic leg for coupling the press plate to the body portion, and providing elasticity to the press plate.

An optical disk clamping apparatus for an optical disk drive, comprising:

• a roller to transfer a disk inserted into the disk drive;
• and
• an elastic member operatively connected with the roller to elastically clamp the inserted disk on a turntable of the disk drive,
• wherein the elastic member comprises:
• a clamping driving member;
• a pressing member operatively connected with the clamping driving member;
• and
• a plurality of elastic supporting arms operatively connected with the clamping driving member and supporting the pressing member, the elastic supporting arms allowing the pressing member to move vertically upon rotation of the clamping driving member, the pressing member operatively pressing the turntable to secure the disk therebetween, and
• wherein the clamping driving member comprises:
• a ring shaped body with a central opening and peripheral slots;
• a pair of arms extending from opposing outer sides of the ring shaped body, the pair of arms respectively being connected with the clamping driving member;
• and
• cam portions formed on the ring shaped body between the pair of arms and the ring shaped body.

An optical disk clamping apparatus for an optical disk drive, comprising:

• a roller to transfer a disk inserted into the disk drive;
• and
• an elastic member operatively connected with the roller to elastically clamp the inserted disk on a turntable of the disk drive,
• wherein the elastic member comprises:
• a clamping driving member;
• a pressing member operatively connected with the clamping driving member;
• and
• a plurality of elastic supporting arms operatively connected with the clamping driving member and supporting the pressing member, the elastic supporting arms allowing the pressing member to move vertically upon rotation of the clamping driving member, the pressing member operatively pressing the turntable to secure the disk therebetween, and
• wherein the pressing member comprises:
• a ring shaped body;
• a plurality of elastic legs extending inwardly from the body;
• a pressing plate connected with the body via the elastic legs;
• and
• a plurality of fixing flaps extending outwardly from the body, the fixing flaps having an opening thereon to allow operative connection with the clamping driving member.

An optical disk clamping apparatus for an optical disk drive, comprising:

• a roller to transfer a disk inserted into the disk drive;
• and
• an elastic member operatively connected with the roller to elastically clamp the inserted disk on a turntable of the disk drive,
• wherein the elastic member comprises:
• a clamping driving member;
• a pressing member operatively connected with the clamping driving member;
• and
• a plurality of elastic supporting arms operatively connected with the clamping driving member and supporting the pressing member, the elastic supporting arms allowing the pressing member to move vertically upon rotation of the clamping driving member, the pressing member operatively pressing the turntable to secure the disk therebetween, and further comprising:
• a first lifting plate operatively connected with the roller and with the clamping driving member;
• a second lifting plate operatively connected with the clamping driving member;
• and
• the first and second lifting plates operating to move the roller away from the disk, while simultaneously moving the clamping driving member.

An optical disk clamping apparatus for an optical disk drive, comprising:

• a roller to transfer a disk inserted into the disk drive;
• and
• an elastic member operatively connected with the roller to elastically clamp the inserted disk on a turntable of the disk drive,
• wherein the elastic member comprises:
• a clamping driving member;
• a pressing member operatively connected with the clamping driving member;
• and
• a plurality of elastic supporting arms operatively connected with the clamping driving member and supporting the pressing member, the elastic supporting arms allowing the pressing member to move vertically upon rotation of the clamping driving member, the pressing member operatively pressing the turntable to secure the disk therebetween, and
• wherein the elastic supporting arm comprises a body portion having one end operatively connected with the clamping driving member, another end portion comprising a supporting flap and a guide flap adjacent to the supporting flap, the body portion having a guide slot and a bent portion.
