FIG. 14 is a plan view showing a state in which an engaging tool is attached to another embodiment of the CD storage tray according to the present invention shown in FIG. 13. The CD storage tray-1 of this example is provided with a holding member 13 for removing the intermediate material 9 and holding the CD 14 so as to surround the engagement tool 3. By providing this holding member 13, a gap 15 is formed between the back surface of the CD 14 and the bottom material 8 even if the intermediate material 9 is not inserted.
Since the surface of D does not come into contact with the bottom material 8, the surface of the stored CD is not scratched.

FIG. 15 is a plan view showing a state in which the CD storage tray of the present invention is provided with ejection holes at three locations, and FIG. 16 is a plan view of the CD storage tray of the present invention provided with ejection openings at two locations. FIG. 17 is a plan view showing a state, and FIG. 17 is a plan view showing a state in which the CD storage tray of the present invention is provided with an ejection hole at one place.

The number and location of the extraction holes are the same in the case of the CD storage tray shown in FIGS. 11 and 12.

[0018]

Since the present invention has the structure described above, the following effects can be obtained. First, there is an effect that the surface of the CD is not scratched and the compact disc lasts a long time. Secondly, there is an effect that it is easy to store and take out the CD. Thirdly, the present CD storage tray has an effect that color printing can be performed on the storage tray itself by using a paper material. Fourthly, there is an effect that dust does not enter because no gap is formed between the CD and the intermediate material. Fifthly, if the present CD storage tray is made of a paper material, it is easy to process and can be manufactured very easily. Sixth
In addition, since an incinerable material such as a paper material is used, it can be incinerated when it is no longer needed, which has the effect of not adversely affecting the environment. Seventh, there is an effect that the engaging tool for accommodating and fixing the CD in the accommodating groove can be attached and detached very easily. Eighth, the use of rayon as the material of the intermediate material has the effect of preventing static electricity from being generated on the CD. . Ninthly, there is an effect that various printing can be performed on the intermediate material or the bottom material exposed at the extraction hole portion.
