FIG. 2 is a partial view showing an embodiment of a disc tray 20 used in the present invention and a state where the fall prevention shaft 1 of the present invention is fixed. FIG. 4 is a cross-sectional explanatory view. As shown in the figure, the disc tray 20 includes a tray main body 22 having a storage groove 21 for storing the discs 30 one by one, and support frames 23 provided on both sides thereof. The tray main body 22 is generally formed of a synthetic resin, and may be integrally formed as a whole, or a plurality of tray members may be integrated, and the support frames 23, 23 It is used to fix or protect the tray body, and is formed by molding a metal plate, and is generally connected and fixed by a back plate 24 at the rear.

る。Here, the fall-preventing shaft 1 of the present invention can be used for the support frames 23, 23 made of metal.
3, a through hole 2 is provided at a position corresponding to the rotation hole 31 of the disk 30 when the disk is stored in the tray body 22.
5 and 25 are provided.
After the disc 30 is stored in the disc 1, the tip 4 of the drop prevention shaft 1 is inserted through the through hole 25 of one of the support frames 23, and then passes through the hole 31 of each disc 30, and the tip 4 is attached to the other end. It reaches the through hole 25 of the support frame 23.
