Optical disk device
View Patent ↗An optical disc device and a disc changer drive capable of achieving a reduction in cost and number of articles and a reduction in size of the disc drive with a simple configuration rather than the prior art and also carrying out a stable playing/writing operation are provided. An optical disc device includes a playing chassis which is supported turnably on a main body of the disc drive and on which a turntable is installed, a substantially Y-shaped cam groove formed on the playing chassis, a driving lever on which a substantially T-shaped cam groove is formed and which transmits a power to a holding portion of the disc, and a turning lever supported turnably on the main body and engaged with the playing chassis and the cam groove of the driving lever via a driving shaft, wherein a turning of the turning lever is followed by a turning of the playing chassis and a movement of the driving lever that follows the turning of the playing chassis to hold a disc as a series of operations.
1. An optical disc device, comprising:
a main body;
a clamping mechanism which holds a disc releasably on a turntable;
a playing chassis which is supported turnably on the main body and on which the turntable is mounted;
a substantially Y-shaped cam groove which is formed on the playing chassis;
a driving lever on which a substantially T-shaped cam groove is formed and which transmits a power to a holding portion of the disc; and
a turning lever which is turnably supported on the main body and engaged with the playing chassis and the cam groove of the driving lever through a driving shaft,
wherein a turning of the turning lever is followed by a turning of the playing chassis and a movement of the driving lever as a series of operations.
2. The optical disc device according to claim 1 , wherein the driving shaft of the turning lever passes through the substantially T-shaped cam groove of the driving lever and the substantially Y-shaped cam groove of the playing chassis to engage with the cam grooves; and
wherein the playing chassis and the driving lever are moved to follow the turning of the turning lever as a series of operations such that the playing chassis swings when the turning lever being turned pushes the substantially Y-shaped cam groove through the driving shaft and then the driving lever moves when the driving shaft being moved in the substantially Y-shaped cam groove pushes the substantially T-shaped cam groove while maintaining a posture of the playing chassis.
3. The disc changer drive equipped with the optical disc device set forth in claim 1 .
