1 to 5 show a first embodiment of an optical disk storage case according to the present invention. In the drawings, reference numeral 1 denotes an optical disk storage case mainly made of a synthetic resin used for a DVD disk. In the optical disk storage case 1, a lid 4 for opening and closing the optical disk 2 above the optical disk 2 in the storage base 3 is integrally provided on one side of a storage base 3 which is a storage case main body for storing the optical disk 2. Has been established. An optical disk holding portion 5 for holding the outer peripheral edge of the optical disk 2 in a detachable manner is provided on the surface of the storage base 3 inside the case, and both sides of the inner peripheral wall of the optical disk holding portion 5 on the distal end side. An optical disc holder 7 formed with a stopper section 6 protruding from the optical disc holding section 5 in order to prevent the optical disc 2 from coming off in the distal direction, from a base end 8 located on the inner surface of the storage case body. The optical disk 2 stands up toward the front end portion, extends to the hollow portion in an inclined state, and holds the stored optical disk 2 in an inclined state.

The optical disc holder 7 has its base end 8 fixed on the inner surface of the storage base 3. The lid body is formed integrally with the storage base 3 in a state in which the base body 8 is vertically movable with its base end 8 as a base point, and is flexible so as to be urged in a direction in which it is always raised. In a state in which the optical disk 4 is open, the optical disk holder 7 extends from the base end 8 toward the distal end to the hollow portion in a rising and inclined state, and holds the optical disk 2 to be stored in an inclined state. When the lid 4 is opened, the optical disk holder 7 is formed in a hollow portion with the center hole 2a of the optical disk 2 held by the optical disk holder 7 at least above the upper edge of the housing base 3 side wall. By extending the optical disk holder 7, the optical disk holder 7 can be extended to the hollow portion in an ideal form in a stable state, and a suitable optical disk 2 can be taken out and stored. Then, when the cover 4 is closed and engaged with the storage base 3, as shown in FIG. 4, the optical disk holder 7 is pushed and pushed down by the cover 4 to enter the optical disk storage case 1. It is stored. In order to limit the rising height of the optical disk holder 7 to about 20 ° where the optical disk 2 can be easily taken out and stored, the storage base 3 is provided on both sides of the base end portion 8 side of the optical disk holder 7. There are two stopper parts 9 that come into contact with the machine.

As shown in FIGS. 1 and 2, the optical disk holding portion 5 formed on the surface of the optical disk holding member 7 has a width diameter and a depth for abutting and holding at least half of the outer peripheral edge of the optical disk 2. In order to prevent the recording part of the optical disk 2 from being damaged by contacting the bottom surface of the optical disk holding part 5, the optical disk 2 is lifted up by bringing the optical disk 2 into contact only with the outer peripheral edge, which is the non-recording part. The projection (not shown) is provided around. The central portion of the optical disk holding portion 5 is largely notched from the front end portion because it does not come into contact with the optical disk 2 and has nothing to do with storage and removal thereof. Also, the joint side between the optical disk holder 7 and the storage base 3 The optical disk holding section 5 is provided with three hooking pieces 10 for holding the outer peripheral edge of the optical disk 2 between the projection and the projecting section and protruding into the optical disk holding section 5.

It is held in a state of extending into the hollow part. In this state, the outer peripheral edge of the optical disk 2 and the center hole 2a can be easily grasped with two fingers without touching the recording surface of the optical disk 2, and when the distal end of the optical disk 2 is lifted, The optical disk holder 7 does not rise any more due to the stopper part 9, but can lift over only the optical disk 2 and get over the stopper part 6, and by being pulled in the tip direction of the optical disk 2, The optical disk 2 can be easily detached from the optical disk holder 7. Also, contrary to the above-described operation, the optical disk 2 grasped by the finger is slid on the upper part 6 of the stopper while inserting the optical disk 2 into the gap between the optical disk holder 5 and the hooking piece 10 from above the optical disk holder 7. By separating the optical disk 2 at a position where the optical disk 2 has passed, the optical disk 2 fits into the optical disk holding section 5 and is securely held by the optical disk holding member 7. Then, when the lid 4 is closed in this state, the inner surface of the lid 4 comes into contact with the stopper portion 6 of the optical disk holder 7 and is pushed to push down the optical disk holder 7, as shown in FIG. As shown, the optical disk 2 is securely stored in the optical disk storage case 1 while being held by the optical disk holder 7. Then, in this state, the optical disk storage case 1 was turned upside down or swung. However, the optical disk 2 is not detached from the optical disk holder 7 while being fitted to the optical disk holder 5.

In the above-described embodiment, the optical disk holder 7 is described as being movable up and down with respect to the storage base. However, the present invention is not limited to this. The optical disk holder 7 may be set in a state where the optical disk holder 7 is fixedly inclined to the storage base in the inclined state. Even if the optical disk is slightly inclined, the optical disk can be easily gripped and removed and stored as compared with the conventional optical disk storage case.

Further, in the above-described embodiment, the case where the optical disk holder 7 is integrally formed with the storage base has been described. In addition to this, the storage base is integrally provided with an elastic hinge structure, and A structure in which a holder is attached may be used.

Furthermore, in the first and third embodiments described above, the configuration in which the storage base and the lid are integrally formed of a synthetic resin material has been described, but these are also the same as those of the second embodiment. Similarly, the storage base and the lid may be separated from each other, and the lid may be configured to be detachable. At this time, the optical disk holder is extended into the hollow portion with the center hole of the optical disk held by the optical disk holder being at least above the upper edge of the side wall of the storage base, so that the optical disk holder is extended.
