Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case for storing a disc-shaped disc such as a compact disc.

[0002]

[Prior art]

 A storage case for a disk-shaped disc, which is a recording medium such as a compact disc, a CD-ROM, a CD-I, etc., is known, for example, from Japanese Utility Model Publication No. 60-15887. This type of conventional storage case has a rectangular holder body, a storage recess formed on the surface of the holder body with a diameter corresponding to the outer diameter of the disc, and a diameter corresponding to the center hole of the disc. A boss and the like are provided, and notches for allowing the middle finger and the like to dip below the disc are formed at a plurality of locations around the recess. A large number of slits are radially formed from the center of the boss portion, and the boss portion is reduced in diameter by pressing the boss portion, and when the boss portion is released, it is elastically expanded to the original state and returned. Is configured.

Therefore, if the central hole of the disc is aligned with the boss portion and the periphery of the central hole of the disc is pressed, the central hole is elastically fitted to the boss portion and is retained by the boss portion so as not to come off. Is stored in the storage recess. When removing the disc from the storage case, press the upper part of the boss downward with your thumb to reduce the diameter of the boss, and remove the middle finger from the notch formed around the recess below the peripheral edge of the disc. It is carried out by diving into the ground, lifting it up and pulling it off.

[0004]

[Problems to be solved by the device]

 However, such a conventional storage case has a structure in which the disc is held by the expandable / contractible boss portion, and therefore, when the boss portion and the central hole are tightly fitted to each other, the boss portion is removed when the disc is removed. When the boss portion is strongly pressed, the boss portion defined by the slit is damaged, which causes a problem that the disc cannot be securely held thereafter. Further, if the boss portion and the central hole are fitted tightly to each other, the disc cannot be easily taken out, and in addition, when the disc is taken out, the disc is warped, which adversely affects the disc.

Further, in such a holding structure, there is a concern that the elasticity of the boss portion may be deteriorated due to long-term use (several years), and the pressing force to the central hole for holding the disk may be lost. Further, in recent years, due to circumstances such as a CD book held between the papers that make up the book and being distributed in the market, the emergence of a simpler disk holding structure has been desired. The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a disk storage case that can securely store a disk with a simple structure and can be easily taken out. It is in.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a disk storage case according to the present invention comprises a base plate part for protecting a disc, a boss part projecting from the base plate part and inserted into a central hole of the disc, and a projecting part from the base plate part. , At least three flexible claw portions which hold the disc by engaging a plurality of spaced-apart peripheral edges of the disc with the boss portion inserted in the central hole of the disc; At least one of the claws is provided with an operation piece projecting in a direction away from the boss on the upper part of the claw.

[0007]

[Action]

 Storage of the disc is performed by holding the outer peripheral edge of the disc on the substrate portion by at least three claw portions. The disc can be taken out easily by pushing the operating piece to bend the claw outward in the radial direction of the disc and pressing the disc on the side opposite to the bent claw.

The wall portion 401 is formed at a height above the disc 1 in this state.

The boss portion 5 is formed at a position to be inserted into the central hole 1 A of the disk 1 in a state where the disk 1 is arranged substantially in the center of the substrate portion 4. As shown in the sectional front view of FIG. 3, the boss portion 5 is formed so as to bulge into a cylindrical shape from the base portion 4 with an outer diameter slightly smaller than the central hole 1A of the disk 1. The boss 5 is formed so that it can be inserted into and removed from the central hole 1A of the disk 1, and may not have the function of holding the peripheral edge 1C of the central hole 1A of the disk 1 as in the conventional case. . Further, a step portion 15 for separating the recording surface of the disk 1 from the substrate portion 4 is formed in a bulge around the substrate portion 4 of the boss portion 5. The step portion 15 is formed in an annular shape with a small outer diameter so as to come into contact with an inner portion of the recording surface of the disc 1.

As shown in FIG. 1, the claw portions 7, 9, 11 pass through the center of the disc 1 at the outer peripheral edge 1B of the disc 1 in a state of being inserted into the boss portion 5 in the central hole 1A. A part corresponding to the upper part of the center line 17 and a part opposite to this part with the boss portion 5 sandwiched therebetween. Two parts of the outer peripheral edge 1B equidistant from the center line 17, that is, an isosceles triangle. It is provided at the location corresponding to each vertex. As shown in FIGS. 4 and 5, the claw portions 7, 9, 11 are provided with a vertical piece portion 19 standing upright from the base plate portion 4, and at the same height as the step portion 15 inside the lower portion of the vertical piece portion 19. A bulging step portion 21 and a projecting portion 23 protruding from the upper end of the vertical piece portion 19 and sandwiching the outer peripheral edge 1B of the disk 1 in cooperation with the step portion 21, are configured to be flexible. Has been done. An inclined surface 23A is formed on the upper surface of the convex portion 23 so as to become lower toward the boss portion 5 side, and the inclined surface 23A facilitates the engagement of the disc 1 with the claw portions 7, 9, 11.
