The holding case 20 is provided with a convex portion 23 which projects upward and has a smooth upper surface, substantially at the center of the bottom surface of the concave portion 21. The holder 6 is fixed to the upper surface of the convex portion 23. The holder portion 6 is made of resin such as plastic and is composed of a plurality of prisms arranged at substantially equal distances from the center of the convex portion 23 in the outer peripheral direction. The holder part 6 is provided with an inclined part 602 at the upper end of the outer side surface, and a convex part 601 protruding outward is provided below the inclined part 602.

3 holds the bottom surface of the optical disc 50 and the inner wall of the center hole 51, so that the optical disc 50 can be prevented from falling off. Further, when the optical disc 50 is taken out from the optical disc storage case 100, as shown in FIG. 5, the fixed case 30 is rotated in the direction of arrow A to open the upper surface of the holding case 20, and the optical disc 50 from the groove 22.
By holding the outer periphery of the optical disc 50 and pulling the optical disc 50 upward,
00 can be taken out.

[0010]

In the conventional optical disk storage case 100, when the optical disk 50 is stored, the lower end of the center hole 51 of the optical disk 50 is provided with the convex portion 6 of the holder portion 6.
It is necessary to press the optical disc 50 downward in the state of accurately abutting the optical disc 01. It is difficult to align the lower end of the center hole 51 of the optical disc 50 with the protrusion 601 of the holder 6.

If the lower end of the inner wall of the center hole 51 is not exactly aligned with the protrusion 601 of the holder 6, and the optical disk 50 is pressed downward, the tip of the holder 6 will be the center of the optical disk 50. There is a risk that the recording surface of the optical disk 50 may be damaged by coming into contact with the back surface of the optical disk 50 without being inserted into the hole 51, and the data recorded on the optical disk 50 cannot be reproduced.

It is 21 mm, which is slightly larger than the maximum allowable outer diameter 120.3 mm defined by the JIS standard for ordinary 12 cm CDs and DVDs. The upper end of the inner wall of the recess 201 is the inclined portion 20.
2 is provided. The holding case 2 includes shafts 4 protruding horizontally in the rear ends of the left and right outer surfaces. The elastic portion 5 is made of an elastic body such as rubber, a compression spring, or a sponge and has a cylindrical shape, and is fixed to the bottom surface of the recess 201.

The fixed case 3 is a rectangular parallelepiped having a height of about 10 mm and a side length of about 145 mm, and has a recess 31. The length of one side of the concave portion 31 is larger than the length of one side of the holding case 2. The fixed case 3 has holes 302 that are open in the horizontal direction at one end of each of the left and right side surfaces. When the shaft 4 is inserted into the hole 302, the fixed case 3 freely rotates about the shaft 4 as a rotation axis in the arrow A direction and the arrow B direction. The fixed case 3 rotates in the direction of arrow A to open the upper surface of the holding case 2, and rotates in the direction of arrow B to close the upper surface of the holding case 2.

As shown in FIG. 2B, the fixed case 3
Is provided with a convex portion 303 protruding downward in the concave portion 301.
As shown in FIG. 2 (b), the convex portion 303 has a fixed case 3
Is rotated in the direction of the arrow B, and is formed at the center of the recess 201 when the upper surface of the holding case 2 is closed.
The holder portion 6 is made of resin such as plastic and is composed of a plurality of prisms arranged at substantially equal distances from the center of the convex portion 23 in the outer peripheral direction. The holder part 6 is provided with an inclined part 602 at the lower end of the outer side surface, and an upwardly protruding convex part 601 is provided above the inclined part 602.

In the state shown in FIG. 2B, the elastic portion 5
The upper surface of is formed to have substantially the same height as the position of the upper end of the convex portion 601 of the holder portion 6. Further, the distance from the surface of the convex portion 303 to the upper surface of the elastic portion 5 and the distance from the upper end of the convex portion 601 of the holder portion 6 to the surface of the convex portion 303 are substantially the same as the thickness of the optical disc 50. Further, the outer diameter E between the upper ends of the opposed convex portions 601 of the holder portion 6 is made slightly smaller than the inner diameter of the center hole 51 of the optical disc 50 shown in FIG.

FIG. 3 is a diagram showing the optical disc storage case 1, FIG. 3 (a) is a diagram showing a state in which the optical disc 50 is stored in the optical disc storage case 1, and FIG. 3 (b) is FIG. 3 (a).
3C is a view showing a state in which the fixed case 3 is rotated in the arrow B direction from the state of FIG. 3, and FIG. 3C is a state in which the fixed case 3 is further rotated in the arrow B direction from the state of FIG. It is a figure which shows the state which closed the upper surface.

The optical disk 50 is used as the optical disk storage case 1
3A, the fixed case 30 is first rotated in the direction of arrow A to open the upper surface of the holding case 2 and then the optical disc 50 is inserted into the recess 201, as shown in FIG. . The outer periphery of the optical disc 50 is guided by the inclined portion 202 and placed on the elastic portion 5.

Next, as shown in FIG. 3B, the fixed case 3 is rotated in the arrow B direction. As a result, the holder portion 6 is guided and inserted into the inner wall of the center hole 51 of the optical disc 50 by the inclined portion 602. At this time, the holder portion 6 is pressed by the upper end of the center hole 51, so that the tip end of the convex portion 601 bends in the arrow C direction due to elasticity. When the fixed case 3 is further rotated in the direction of arrow B,
As shown in FIG. 3C, the upper surface of the optical disc 50 contacts the convex portion 303, and the convex portion 601 of the holder 6 is released from the pressure of the inner wall of the center hole 51 and moves in the direction of arrow D. At this time, the optical disc 50 is held by the convex portion 303, the convex portion 601 of the holder portion 6 and the elastic portion 5. Therefore, the optical disc 50 is held in the optical disc storage case 1.

The optical disk storage case of this embodiment holds the optical disk 50 pressed against the convex portion 303 by the elasticity of the elastic portion 5 when the fixed case 3 is closed. Therefore, the optical disc storage case 1 can store the optical disc 50 without rattling.

FIG. 4 is a view showing a state in which the fixed case 3 is rotated in the direction of arrow A from the state shown in FIG. 3 (c). When taking out the optical disk 50 from the optical disk storage case 1, as shown in FIG.
Rotate in the direction. At this time, in the optical disc 50, the upper surface and the lower end of the inner wall of the center hole 51 are the convex portion 303 and the holder portion 6.
Since it is sandwiched between the convex portions 601 of FIG. In this state, the optical disc 50 can be taken out from the optical disc storage case 1 by gripping the outer periphery of the optical disc 50 and pulling out the optical disc 50.

From the above, the optical disk storage case 1 is
As shown in FIGS. 3A, 3B, and 3C, the optical disc 50 is inserted into the recess 201 of the holding case 2 and the fixed case 3 is rotated in the arrow B direction.
Can be stored. In the optical disc storage case 1 of the present embodiment, the inclined portion 202 guides the outer circumference of the optical disc 50 and inserts it into the concave portion 201 without inserting the optical disc 50 into the concave portion 201 accurately. It is possible to facilitate the work of placing the device on the table 5.

The optical disc 50 housed in the optical disc housing case 1 has a convex portion 303 and a convex portion 601 of the holder portion 6.
Since it is held by the elastic portion 5 and the elastic portion 5, for example, the optical disc storage case 1 in which the optical disc 50 is stored is stored.
It is possible to prevent the optical disc 50 from falling off the optical disc storage case 1 even if the optical disc is tilted or inverted.

When the optical disc 50 is taken out from the optical disc storage case 1, the optical disc 50 can be easily taken out from the optical disc storage case 1 by rotating the fixed case 3 in the direction of arrow A as shown in FIG. You can
