This case includes a casing 1 that opens and closes in the direction of arrow A around a hinge 2, and a plate 5 on which a disc-shaped CD 3 is placed is accommodated inside the casing 1. Generally, a commercially available CD 3 has a plane circular hole 4 of about 14 mm at the center, and the CD 3 is placed and stored in a circular placing portion 6 formed on the upper surface of a plate body 5. The plate body 5 including the mounting portion 6 is formed entirely of a synthetic resin material.
At the center of the upper surface of the mounting portion 6, a convex engaging portion 7 having a flat circular shape is formed. The convex engaging portion 7 has a central hole 8 at the center, and a plurality of cuts 9 following the central hole 8 are formed at equal intervals in a radial direction around the central hole 8. That is, the engaging portion 7 is composed of a plurality of tongue pieces 10 extending from the outside to the inside in the radial direction as shown in FIG. 19, and by applying a pressing force P to these tongue pieces 10 from above by a finger, As shown in FIG. 20, the outer diameter T of the engaging portion 7 is reduced,
By releasing the application of the pressing force P, the outer diameter T of the engaging portion 7 can be increased. This is because the plate body 5 forming the engaging portion 7 is formed of a flexible synthetic resin material, and each tongue 1
This is made possible by bending 0 inward.

[0004] In this manner, by applying a pressing force to or releasing the pressing force from each tongue piece 10 of the engaging portion 7, the outer diameter T of the engaging portion 7 can be expanded and contracted.
The hole 4 of D3 can be detachably attached to the engaging portion 7.
That is, when the CD 3 is engaged with and held by the engaging portion 7, the hole 4 may correspond to the engaging portion 7, and the center position of the upper surface of the CD 3 may be pressed against the mounting portion 6 from above by a finger. . As a result, the hole 4 of the CD 3 is held by the engaging portion 7 as shown in FIG. When the CD 3 is disengaged from the engaging portion 7, as shown in FIG.
The pressing force P may be applied from above by a finger, and the CD 3 may be taken out from the mounting portion 6 while holding both ends of the CD 3.
