The present invention provides a disk apparatus reduced in size, thickness and weight, by reducing a space for carrying a disk and a space between the floating unit and the stationary frame for use in holding the floating unit in a floating state, as much as possible, with a simple structure. In the disk apparatus of the present invention, the floating unit held in a floating state in the stationary frame is so arranged that the roller arm can rotate itself, pressing a disk-shaped recording medium onto the disk guide provided on the stationary frame, to carry the disk-shaped recording medium to a desired position.

Disk apparatus

There is provided a disc device achieving a reduced thickness by reducing as much as possible the space required for sandwiching operation by a turn table and a clamper while assuring the space where an inserted disc is conveyed inside the device. The disc device includes: a clamper unit having a clamper for sandwiching a disc-shaped recording medium by a floating unit held via an elastic member to a fixed frame; and a disc recording/reproduction drive unit having a turn table. The disc device is configured so that when the disc-shaped recording medium is sandwiched, a part of the clamper and a part of the turn table are contained in each other.

The present invention provides a highly reliable disk apparatus which is reduced in size, thickness and weight, and which can surely prevent the double insertion of disk-shaped recording media with a simple structure to thereby prevent a contact between each of the disk-shaped recording media. In the disk apparatus of the present invention, a disk guide is rotatably held in the proximity of an opening for inserting and ejecting a disk-shaped recording medium, which is formed in the stationary frame fixed to the casing, and the disk guide leads the disk-shaped recording medium to the inserting and ejecting operations and also closes at least a part of the above opening.

The present invention provides a disk apparatus reduced in size and thickness, by reducing the size of a means which detects the insertion of a disk into the disk apparatus. In the disk apparatus of the present invention, an electric circuit board and disk insertion-detecting levers are provided on the floating unit, and the disk insertion-detecting levers are disposed in the proximity of the disk insertion/extraction port, and are pressed down and rotated by the outer edge of the inserted disk-shaped recording medium, to thereby directly drive a switch which outputs a disk detection signal to the electric circuit board.

Disk apparatus having disk insertion detecting levers disposed in plane of disk and rotatable in axial direction relative to disk

A drive mechanism for moving a clamper arm into a standby position of the clamper is simplified and the possible occurrence of the vibration of the clamper in the standby state and the falling of the disc out of the tray in the transferring stage are prevented with a relatively simple construction. Provided is a disc clamping device having a turntable and a clamper which faces the turntable, operating to rotatively support a disc on the turntable with the disc pressed by the clamper, the device being provided with a clamper arm which rotatably supports the clamper and is able to pivot approximately in the direction of its axis of rotation, moving the clamper between a disc pressing position and a standby position, and a clamper arm moving means having a clamper urging plate which pivots the clamper arm as engaged with this and urges the clamper arm toward the turntable side at least in the disc pressing position, whereby the disc is urged against the turntable by the urging force of this clamper urging plate.
