Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a storage case for a compact disc, which is a digital audio disc.

Conventional configuration and its problems Compact discs, which are digital audio discs, are made by carving a digital focus train signal on a resin substrate, providing a reflective film, irradiating this with a semiconductor laser, and digitally measuring the difference in reflectance. The music is played back by processing the data into analog data and converting it to analog.

Compact discs have a low S/N ratio, low noise, excellent frequency characteristics, and large dynamic range separation, and are seen as a promising music medium and are being commercialized rapidly.

Because the Konbaku I Disk has a polycarbonate resin substrate, it is easily scratched, and is housed in a case to protect it from environmental impacts such as temperature and humidity. FIG. 1 shows a conventional compact disc storage case. 1 is a disc, 2 is a tray for placing the disc, and 3 is a case. In this case, one case is required for each disc, which increases the cost and the size. Furthermore, karaoke machines and changers need to store multiple discs, but since it is impossible to take out and insert discs one by one in such cases, they are not suitable as cases for karaoke machines or changers. However, there are some problems, such as that it is possible.

OBJECTS OF THE INVENTION The present invention solves these problems and provides a compact disc storage case that can store a plurality of discs and also allows easy loading and unloading of discs.

Structure of the Invention The present invention provides a rectangular parallelepiped-shaped container that is open on one side and can accommodate a plurality of disks, and is provided with protrusions that hold both sides of the disk end face and slide the disk, and that a disk is inserted between the protrusions. This is a compact disc storage case with a mechanism for storing discs.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows an embodiment of the compact disc storage case of the present invention. FIG. 2a shows a front view, and FIG. 2a shows an enlarged sectional view of the main part.

A disk 1 is placed in a part of the disk storage case 4 shown in FIG.
The disc 1 is placed between the protrusions 5 which can hold both sides of the end face of the disc and slide the disc thereon.

FIG. 3 shows the disc stocker mechanism of the compact disc storage case of the present invention, and this mechanism is provided in the case shown in FIG. Figure 3a is a plan view;
The figure shows a cross section. The disc 1 is provided with a projection 5 that can hold both sides of the end face of the disc 1 and slide the disc at the same time, and a jig 6 for stocking the disc is provided between the projections 6. This stock jig 6 is
Normally, it is protruded by a spring 7 to prevent the disc from protruding. By pushing the lever 8, the stock jig 6 is stored and the disc can be taken out.

The stock mechanism shows one embodiment, and an externally driven operation may be used in the case of a changer or a karaoke compact disc player. Further, each case of the present invention can be stored in the player, and a CD playback system that can store many compact discs and easily play selected songs can be realized.

Effects of the Invention As described above, according to the present invention, a rectangular parallelepiped-shaped container capable of accommodating a plurality of disks with an open side is provided with protrusions that hold both sides of the disk end surface and allow the disks to slide. If there is a mechanism for stocking discs between the protrusions mentioned above, it will be possible to store multiple discs, it will be possible to use autochanger specifications such as one-shot selection of one song of the desired type, and it will prevent scratches on the disc surface. It is characterized by its ability to withstand dust, temperature, humidity, and other external environments as well as shock, allowing compact discs to be safely stored for a long time.
