PURPOSE:To improve reliability by providing fitting pieces which are inserted into and extracted from the storage part of a frame freely and a fitting tool which permits a storage medium to be attached and detached freely. CONSTITUTION:When an optical disk 8 is to be stored with the fitting piece 6 of a frame 2, the fitting piece 6 is taken out of a storage part 3 by being rotated around a hinge 7 as a fulcrum as shown by an arrow A, and a nut 10 and a disk 11 fitted around the bolt 9 of the fitting part 6A of the fitting piece 6 are detached; after the bolt 9 is inserted into the through hole made in the center of the optical disk 8, the disk 11 is fitted around the bolt 9 and the nut 10 is turned up. Then, the fitting piece 6 is rotated around the hinge 7 as the fulcrum as shown by an arrow A' to be stored in the storage part 3 of the frame, thus storing the optical disk. This operation is repeated successively to store the optical disks in the storage case 1. |
