Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is for storing and storing an optical disk on which music or images are recorded, a record disk on which other information is recorded, or a recordable disk. The present invention relates to a disk storage device used in.

[Conventional technology]

An optical disc used in a conventional optical disc player has music, video, or other information signals recorded on one side as a fine pit sequence, and a metal material such as aluminum is deposited on the signal recording surface. A transparent synthetic resin substrate provided with a laser beam reflection film and a protective layer for protecting the reflection film are integrally laminated on the substrate. The optical disc is mounted on a player, and the information signal recorded as the pit train is read by the laser beam from the optical pickup device and reproduced by the optical detecting element.

Since the information signal is read by the laser beam on the optical disk as described above, when the transparent substrate surface irradiated with the laser beam is scratched or oil or other dust is attached, the laser beam is diffusely reflected. As a result, the reading of the information signal recorded as the pit train is lost, and the good reproduction state is impaired.

Therefore, in order to prevent scratches and dust from adhering, a disk case is used as a disk storage device that completely stores a disk.

In a conventional disc storage device, a plate-shaped tray main body having a recess for storing a disc and a transparent lid body covered on the upper surface of the recess side are provided, and the tray body and the lid body have one side thereof. The edges are connected by so-called hinges, and the disc is securely protected in the disc storage device by storing the disc in the recess of the tray body and closing the rear lid.

[Problems to be solved by the invention]

In such a disc storage device, the disc can be protected as described above in the state where the disc is stored. On the other hand, when the disc is taken out from the disc storage device, the tray main body is turned over to remove the disc. There is a problem in that if you take it out from the disc storage device by using one hand from below and take it out, and if you do not catch it with your hand, you may drop it and damage the disc, especially for passenger cars. In the case of a so-called car stereo equipped with a playback device for these optical discs, the conventional disc storage device cannot take out the disc at all during operation, and the car stereo device can be operated with one hand like a conventional tape cassette. It was impossible to put on and take off.

[Means for solving problems]
