However, the conventional CD disk illumination as described above has the property that the vapor deposition mirror surface portion of the CD disk is irradiated with light from the LED lamp.
You can only peek at the top CD disc, but in devices that can be prepared by putting multiple CD discs inside the device, such as the multiplayer CD players that have become rapidly popular in recent years, There is a problem that it is not possible to visually confirm how many CD discs are prepared inside the device.

In view of the above-mentioned problems of the prior art, the present invention has a very simple structure for all CD disks waiting for performance prepared in the equipment in the CD disk illumination of a CD player having a plurality of sheets. The purpose of the invention is to provide a CD disc illumination that can be visually confirmed at low cost.

[0008]

In order to solve the above-mentioned problems, the CD disc illumination according to the present invention is a CD player having a plurality of sheets, in which the disc to be played is arranged behind the device and the disc waiting to be played is the device. The non-evaporated transparent part of the inner circle of the disc waiting for performance is illuminated by the CD mechanism placed on the front of the disc and the light source such as the LED lamp placed on the top of the disc on the side of the performance of the disc. By transmitting light through the inside of the disc itself, the outer edge of the disc itself is illuminated so that the presence or absence of a pending disc can be seen directly from the outside of the device, and the part that covers the unvaporized transparent part of the disc is removed. Each disc is held by a tray with a meat opening, and a plurality of trays are arranged in a stack, with the undeposited transparent parts of each disc overlapping and By arranging it vertically to the optical axis direction of the light source such as the LED lamp arranged at the top of the disc, the light emitted from the light source reaches the bottom layer of the disc with a plurality of layers stacked and is ready for performance. The shining condition of all the outer edges of the existing disk can be easily visually checked from the outside of the device.

[0009]

According to the present invention, with the above-mentioned structure, a CD waiting to be played
The transparent portion, which is the non-evaporated surface of the inner circle of the disc, is irradiated with light from a light source such as an LED lamp, and the light is transmitted inside the disc itself so that the outer edge of the disc itself is illuminated and the light is emitted. Utilizing transmitted light in the axial direction,
