[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc case, and more particularly to improvement of a mechanism for attaching and detaching a disc to a case body.

[0002]

[Prior Art]

 Conventionally, a disk case of this kind has a case body C having a circular concave portion A and a disc locking portion B at the center of the concave portion A on the upper surface, and a case body C which can be freely opened and closed, as shown in FIGS. It is composed of a provided cover D. The disk E is fixed in the concave portion A of the case body C so that the locking portion B is inserted and locked while being deformed in the center hole F, and the lid body D is closed to completely store and hold it in the case. Be done. When the disk E is removed from the case body C, the locking portion B may be deformed in the central direction.

[0003]

[Problems to be solved by the device]

 However, in this case, the reduction amount of the diameter of the locking portion B is small, the surface of the center hole F is rubbed when removed, and the bending stress acts on the disk E. Further, it is necessary to press the two points in the diameter direction of the disk E and the three points of the center hole F, and there is a problem that the removal is troublesome. Therefore, an object of the present invention is to provide a disk case in which the disk can be easily removed without applying bending stress to the disk.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve the above-mentioned object, the present invention provides a case body having a concave portion for accommodating a disc and a groove portion traversing the central portion of the concave portion, a pair of disc support members arranged in the groove portion of the case body, and a case. A pair of disc supports, which are movable along at least the groove, and a locking part projecting from the opposite end of the main part. The main body of the disc support is supported by the case main body by an elastic supporting member, and a coil spring is arranged between the pair of main bodies.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. 1, 2 and 4. In the figure, reference numeral 1 denotes a case main body, on the upper surface of which a circular concave portion 2 and a groove portion 3 crossing the concave portion 2 and having a U-shaped cross section are formed. A pair of disk supports 4 and 4 are arranged in the groove 3. The disc support 4 is composed of, for example, a main body portion 5 movable along the groove portion 3 and a locking portion 6 protruding from the end portion (center side) of the main body portion 5. Incidentally, a taper portion is formed on the engaging portion 6 as shown in FIG. 4 in order to facilitate the attachment / detachment of the disc. On the other hand, for example, a U-shaped lid 7 is provided at the end of the case body 1 so as to be openable and closable. The side surfaces 7a, 7a of the lid 7 cover the side surfaces of the case body 1 and the body 5. The disc support 4 is arranged in the groove 3, the body 5 is supported by the leaf spring 8, and one end thereof is supported by the fixed columns 9 and 10. Next, the operation will be described. First, the disk E shown in FIG. 6 is placed in the recess 2 of the case body 1. Next, the outer ends of the main body portions 5, 5 are pressed and moved toward the center of the recess 2. Then, the diameters of the locking portions 6, 6 are reduced, and the locking portions 6 are inserted into the center hole F of the disc E. In this state, when the pressing of the main body portions 5 and 5 is released, the main body portions 5 and 5 are restored by the restoring force of the leaf spring 8 and the locking portions 6 and 6 securely support the disc 1. When the lid 7 is closed in this state, the outer ends of the case body 1 and the body portions 5 and 5 are also covered, so that the disc cannot be attached or detached by operating the body portions 5 or 5. FIG. 3 shows another embodiment of the present invention, in which a pair of rails 12 and 12 are provided in the groove portion, and the main body portions 5 and 5 are movably attached to the rails 12 and 12, respectively. It is arranged. A coil spring 11 is arranged between the opposing portions of the main body portions 5, 5. According to this embodiment, when attaching / detaching the disk E as in the above embodiments, the main body portions 5 and 5 are moved along the rails so that the side surface of the center hole is not rubbed by the engaging portion 6. Easy to install and remove.

[0006]

[Effect of the device]

 As described above, according to the present invention, by moving and operating the disc support, the disc can be easily attached to the case without holding bending stress or friction by holding the disc at two points. There is an effect that can be removed from.
