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.
