Abstract

An optical disk apparatus includes a frame 2 which receives internal devices and can receive an optical disk 27 , a tray 5 on which the optical disk 27 is rotatably mounted, a rail 4 which supports the tray so as to be moved between a mounting position where the optical disk 27 is detachably mounted and a receiving position where the optical disk 27 is received in the frame 2 , a tray moving means which moves the tray 5 between the mounting position and the receiving position, a tray receiving releasing member which receives and release the tray 5 at the receiving position, and an optical disk rotation suppressing member which exerts a pressing force on the optical disk in cooperation with a tray releasing operation of the tray receiving releasing member and releases the pressing force in cooperation with a tray receiving operation of the tray receiving releasing member.

Claims (28)

1. An optical disk apparatus, comprising:

a frame that receives internal devices and is structured to receive an optical disk;

a tray that rotatably mounts the optical disk thereon;

a rail that supports the tray to be movable between a mounting position where the optical disk is detachably mounted and a receiving position where the optical disk is received in the frame;

a tray receiving releasing member that releases the tray from the frame; and

an optical disk rotation suppressing member that exerts a pressing force on a circumferential portion of the optical disk in cooperation with a releasing operation of the tray receiving releasing member to stop rotation of the optical disk,

wherein the tray receiving releasing member includes:

a fixing releasing member which releases fixing of the tray and the frame; and

a latching solenoid that maintains the receiving position by a suction force of a permanent magnet to a metal piece, and

wherein the tray receiving releasing member includes a compulsory ejection member that removes the suction force by exerting a compulsory force on the fixing releasing member to release the receiving position.

2. The optical disk apparatus according to claim 1 , wherein the optical disk rotation suppressing member releases the pressing force in cooperation with the receiving operation of the tray receiving releasing member.

3. The optical disk apparatus according to claim 1 , wherein the tray receiving releasing member functions as a rotation suppressing operation member that suppresses a rotational force of the optical disk by the optical disk rotation suppressing member pressing the circumferential portion of the optical disk in a central direction of the optical disk.

4. The optical disk apparatus according to claim 1 , wherein the tray receiving releasing member functions as a pressing force exertion releasing member that removes a force used for operating the optical disk rotation suppressing member in a direction where the rotational force of the optical disk is suppressed.

5. The optical disk apparatus according to claim 1 , wherein the tray receiving releasing member functions as a pressing force exertion releasing member that removes a force used for allowing the optical disk rotation suppressing member to exert the pressing force on the optical disk.

6. The optical disk apparatus according to claim 5 , wherein the eject lever is constructed to move in a direction substantially equal to a direction of a force that is exerted on the compulsory ejection member.

7. The optical disk apparatus according to claim 1 , wherein a thickness of the frame constituting a thickness of the optical disk apparatus is 9.5 mm or less.

8. An optical disk apparatus, comprising:

a frame that receives internal devices and is structured to receive an optical disk;

a tray that rotatably mounts the optical disk thereon;

a rail that supports the tray to be movable between a mounting position where the optical disk is detachably mounted and a receiving position where the optical disk is received in the frame;

a tray receiving releasing member that releases the tray from the frame; and

an optical disk rotation suppressing member that exerts a pressing force on a circumferential portion of the optical disk in cooperation with a releasing operation of the tray receiving releasing member to stop rotation of the optical disk,

wherein the tray receiving releasing member includes:

an eject lever that releases the receiving position of the tray in the frame;

a latching solenoid that maintains the receiving state by a suction force of a permanent magnet to a metal piece, and

a compulsory ejection member that releases fixing of the tray and the frame by releasing the suction force by receiving a compulsory force to the eject lever, and

wherein the compulsory ejection member moves the eject lever in parallel to a direction substantially equal to a direction where the eject lever is exerted by the compulsory force so as to press the optical disk rotation suppressing member to the circumferential portion of the optical disk.

9. The optical disk apparatus according to claim 8 , wherein the eject lever is constructed to move in a direction substantially equal to a direction of a force that is exerted on the compulsory ejection member.
