FIG. 2 is a view in which a part of the case 1 is cut away. When the CD 3 is inserted into the case 1, it is set at a predetermined position by a positioning projection 5 provided on a side portion or an inner wall of the case 1. A disc holder 7 that moves up and down is provided right below a base wall surface 6 (lower side in the drawing) of the case 1 facing the hole 2 of the CD 3 at this position. Also, the CD stored in the case 1 on the other wall surface 8 (upper side in the drawing) of the case 1.
A circular through hole 9 is formed at a position facing the hole 2 of No. 3 of FIG.

FIG. 3 is a perspective view of the disc holder 7.
The disk holder 7 is formed integrally with the base wall surface 6, and has a substantially columnar fitting projection 10 having a circular outer shape that fits into the hole 2 of the CD, and a radial shape around the fitting projection 10. It is composed of three arms 11 provided in the arm 1. One end of the arm 11 is integrally connected to the fitting protrusion 10 and the arm 1
The other end of 1 is integrally connected to the base wall surface 6 of the case 1. Then, the fitting protrusion 10 of the base wall surface 6 and the arm 1
A cut groove 12 is formed in the periphery of the disk holder 7 made of 1 except for a connecting portion between the arm 11 and the base wall surface 6, and the disk holder 7 can be retracted inside or outside the base wall surface 6.

The disc holder 7 moves up and down the position of the hole 2 of the CD in the case 1, but does not stop in the middle of its stroke, so that it has a click feeling and limits the movement and the length of the stroke. The hinge structure on the side of the fitting protrusion 10 and the hinge structure on the side of the base wall 6 which are arranged to face each other or in a radial pattern, and the shape is set to have bending elasticity and a plurality of materials made of an elastic material. It is held on the base wall surface 6 via the arm 11.

The hinge structure shown here is obtained by thinning a part of a structure made of polyolefin resin such as polypropylene in a linear shape so as to have flexibility, and in the drawing, a fitting protrusion. The hinge structure on the side of the portion 10 has a bent portion 13 formed by thinly forming a thin groove by linearly forming a groove in the lower surface (outer side) of the arm 11 in a direction orthogonal to the longitudinal direction of the arm 11. In the hinge structure, a bent portion 14 is formed on the upper surface (inside) of the arm 11 so as to have a linear groove in a direction orthogonal to the longitudinal direction of the arm 11 and to be thinly formed.

Also, the fitting projection 10 of the disk holder 7 is lifted by pressing from the lower surface of the fitting projection 10 with a fingertip, fits into the hole 2 of the CD, and penetrates to the opposite surface of the CD 3. It is desirable that there is a height and the position is C
