In the above-mentioned conventional example, since the notch 8 having the same circular arc shape as the circular arc on the outer periphery of the disk 5 is formed in the partition plate 7 of the magazine 3, the position of the partition plate 7 is slightly shifted. If the disk 5 is deformed such as "sludge", when the disk 5 is stored in the magazine 3,
There has been a problem that the outer peripheral surface of the disk 5 simultaneously hits the end of the notch 8 of the partition plate 7, and the disk 5 cannot be stored in the magazine 3.

In the above-mentioned conventional example, since the disk 5 is held in the magazine 3 by the elastic force of the leaf spring 9, if the elastic force of the leaf spring 9 is weak, a strong impact is applied to the magazine 3. In addition, there is a problem that the disk 5 jumps out of the magazine 3. If the elastic force of the leaf spring 9 is strong, the load of the disk loading mechanism for taking out the disk 5 from the magazine 3 or storing the disk 5 in the magazine 3 again is increased. There was a growing problem.

[0006]

As described above, in the conventional disk magazine, when the position of the partition plate 7 in the magazine 3 is slightly shifted or a deformed disk is used, the outer periphery of the disk 5 There is a problem that the disc 5 cannot be stored in the magazine 3 at the same time as the end of the notch 8 of the partition plate 7, and the disc 5 jumps out of the magazine 3 when a shock is applied due to the strength of the elasticity of the leaf spring 9. Or the load on the disc loading mechanism increases.

The present invention solves the above-mentioned conventional problems. Even if the position of the partition plate 7 in the magazine 3 is slightly shifted or a deformed disk is used, the disk 5 can be easily loaded in the magazine. And the disk 5 does not fly out of the magazine 3 when an impact is applied.
Another object of the present invention is to provide a disk magazine in which a load on a disk loading mechanism does not increase.
