As shown in these drawings, the mini-disc cartridge storage case A includes an upper case 1 and a lower case 2. The upper case 1 is formed of a top plate 11, side plates 12 and 13 adjacent to the opening surface 3, and a rear plate 14 facing the opening surface 3. The lower case 2 is formed of a bottom plate 21, side plates 22 and 23 adjacent to the opening surface 3, and a rear plate 24 facing the opening surface 3.
[0009]
3 and 4 show the mini disk cartridge B. FIG. The mini disk cartridge B is formed of a synthetic resin and has a rectangular shape. Inside, a mini disk 4 as a recording medium is rotatably stored. The mini disk 4 has a central rotating portion 5. A recording / reproducing opening 6 is provided on one side surface, and the recording / reproducing opening 6 can be opened and closed by a slidable shutter unit 7. Further, a pair of recesses 8 and 9 are provided at the end of the lower surface of the mini disk cartridge B. By using the recesses 8 and 9, the mini disc cartridge B is locked in the mini disc cartridge storage case A and fits snugly.
[0010]
In the upper case 1, the top plate 11 is approximately the same size as the mini disc cartridge B as shown in FIG. Side plates 12 and 13 are formed at both end portions of the lower surface of the top plate 11. A rear plate 14 is formed at the rear end facing the opening surface 3 on the lower surface. The heights of the side plates 12 and 13 and the rear plate 14 are set equal to the thickness of the mini disc cartridge B. The side plates 12 and 13 and the rear plate 14 are integrated with the top plate 11.
[0011]
A cutout portion 15 is provided on the opening surface side of the top plate 11 so that the mini disc cartridge B can be easily taken out from the mini disc cartridge storage case A.
[0012]
Engaging grooves 16 and 17 are formed inside the side plates 12 and 13. These engagement grooves 16 and 17 are provided in parallel with the top plate 11 at substantially the center inside the side plates 12 and 13. When the upper case 1 and the lower case 2 are combined, the upper case 1 and the lower case 2 are designed to slide.
[0013]
Further, at a position adjacent to the inside of the side plates 12 and 13 on the lower surface of the top plate 11, the position is 10 to 20 mm from the opening surface 3, that is, a position within a range in which the upper case 1 and the lower case 2 slide. The locking projections 18 and 19 for stopping the slide are provided. The high portions of the side plates 22 and 23 of the lower case 2 hit the locking projections 18 and 19, and the sliding of the upper case 1 and the lower case 2 stops. Next, the sliding width is set to about 10 to 20 mm, which is the width at which the mini disk cartridge B can be easily taken out. By providing the notch 15 on the opening surface 3 side of the top plate 11, the sliding width can be reduced.
[0014]
Examples of the material of the upper case 1 include polystyrene resin, polyvinyl chloride resin, polypropylene resin, acrylic resin (polymethyl methacrylate, etc.), polycarbonate resin, polyester resin, polyamide resin, acetal resin, acrylonitrile-butadiene-styrene resin, and the like. For example, it can be manufactured using a known molding method such as injection molding or extrusion molding. The upper case 1 is preferably made of a transparent material, so that the mini-disc cartridge B can be easily seen.
[0015]
Next, in the lower case 2, the bottom plate 21 has substantially the same size as the mini disc cartridge B as shown in FIG. Side plates 22 and 23 are formed at both end portions of the upper surface of the bottom plate 21. Then, a rear plate 24 is formed at the rear end facing the opening surface 3 on the upper surface. The heights of the side plates 22 and 23 and the rear plate 24 are set to be equal to the thickness of the mini disk cartridge B, but a portion of 10 to 20 mm from the opening surface 3 is provided with a step so as to be lowered. The width of this step is equal to the height of the locking projections 18 and 19 provided in the upper case 1. When the upper case 1 and the lower case 2 are slid, as shown in FIG. 7, the high stepped portions of the side plates 22 and 23 of the lower case 2 hit the locking projections 18 and 19, and the sliding stops. . The side plates 22 and 23 and the rear plate 24 are integrated with the bottom plate 21.
[0016]
A cutout portion 25 is provided on the opening surface side of the bottom plate 21 to facilitate removal of the mini disc cartridge B from the mini disc cartridge storage case A.
[0017]
Engagement ridges 26 and 27 are formed outside the side plates 22 and 23. These engaging ridges 26 and 27 are provided substantially in the center of the inner sides of both side plates 22 and 23 and parallel to the top plate 11. It is designed to slide when the upper case 1 and the lower case 2 are combined. The storage case A for the mini disc cartridge formed by fitting the upper case 1 provided with the engaging grooves 16 and 17 and the lower case 2 provided with the engaging protrusions 26 and 27 has a cross section parallel to the opening surface 3. As shown in FIG. However, the shape is not limited to this shape as long as the upper case 1 and the lower case 2 can be slid. For example, the shapes shown in FIGS. 8B and 8C may be used.
[0018]
Further, in the lower case 2, the position close to the opening surface 3 of the bottom plate 21 and close to the side plates 22 and 23, or the position close to the opening surface 3 of the both side surfaces 22 and 23 and adjacent to the bottom plate 21, that is, When the mini disc cartridge B is stored in the mini disc cartridge storage case A, a pair of locking projections 28 and 29 are provided at positions corresponding to the recesses 8 and 9 provided on the lower surface of the mini disc cartridge B. The disk cartridge B is easy to be accommodated in the mini disk cartridge storage case A, and is prevented from falling off. As a method of providing the locking projections 28 and 29, there are a method of simply providing a locking projection on the bottom surface 21 or both side surfaces 22 and 23 and a method of providing a locking projection having a spring effect.
The former is provided with convex portions having a height and area slightly smaller than the size of the concave portions 8 and 9 provided on the bottom surface of the mini-disc cartridge B on the bottom surface 21 or both side surfaces 22 and 23, and the locking projections 28 and 29. To do. (The figure is omitted.)
The latter is a method used when it is provided on the bottom plate 21, and as shown in FIG. 9, a cut groove 30 is provided around the locking projections 28 and 29, and the remaining portion 31 has a spring effect. Improve the fit of cartridge B.
[0019]
The material of the lower case 2 is, for example, polystyrene resin, polyvinyl chloride resin, polypropylene resin, acrylic resin (polymethyl methacrylate, etc.), polycarbonate resin, polyester resin, polyamide resin, acetal resin, acrylic, as with the upper case 1. Nitrile-butadiene-styrene resin or the like can be used, and for example, it can be produced using a known molding method such as injection molding or extrusion molding.
[0020]
Actually, in order to take out the mini-disc cartridge B from the mini-disc cartridge storage case A with one hand, as shown in FIG. 10, first, the upper case 1 is slid in the direction opposite to the opening surface 3 with a finger, Then, the mini disk cartridge B is taken out in the direction of the opening surface 3 with the same finger.
[0021]
