The dedicated cassette case 5 is integrally formed of synthetic resin, so that it has a flat board 5A having almost the same size as the cassette 4, as shown in FIGS. 6 and 8.
and a rising wall 5B rising from the side of the surface of this substrate 5A.
and a pair of left and right walls having the same size as the substrate 5A and having one end side attached integrally or separately to the upper end of the rising wall 5B, or having a length substantially equal to the length of the rising wall 5B. and a cover plate 5C connected via a hinge portion 25 (see FIG. 9), and each reel hole 1 of the cassette 4 is provided approximately at the center of the surface of the substrate 5A.
A pair of left and right cylindrical bodies 26A and 26B into which the cassettes 2 and 2 are respectively fitted to position the cassette 4 are protrudingly provided.

The inner holes 27 of these cylindrical bodies 26A and 26B constitute a through hole, and the inner diameter thereof is larger than the outer diameter of the cylindrical portion 9A of the protrusion 9 (same as the protrusion 23 of the i-body 3) protruding from the case body 2. It is set to a slightly medium size.

Further, on the surface of the substrate 5A and in the center of the end on the side of the rising wall 5B, there is a recess 28 for allowing one of the protrusions 29 provided on both sides of the cassette 4 to escape when the cassette 4 is stored.
It is provided.

Therefore, a portion on the back surface of the substrate 5A corresponding to the recess 28 constitutes a protrusion 30, and the height Dl of the protrusion 30 is approximately equal to the height Hl of the protrusion 29 of the cassette 4 and the case The height H of the large diameter portion 9B of the protrusion 9 protruding from the main body 2 is set to be approximately the same or slightly smaller than the height H (see FIG. 5).

On the other hand, on the inner surface of the cover plate 5C, that is, the surface facing the surface of the substrate 5A when the lid is closed, a pair of left and right small diameter cylindrical bodies 3 are provided corresponding to the pair of cylindrical bodies 26A and 26B.
1A and 31B are provided protrudingly.

These pair of small diameter cylindrical bodies 31A, 31B are the cylindrical body 26A,
26B, and its outer diameter is set to be approximately the same as or slightly larger than the inner diameter of the inner hole 27.

Therefore, when the cover plate 5G is closed, the pair of small-diameter cylindrical bodies 31A and 31B are tightly fitted into the inner holes 27 of the respective cylindrical bodies 26A and 26B, and are not easily opened due to vibration or the like.

Further, a trapezoidal recess 32 is formed on the inner surface of the cover plate 5C and at the center of the end on the side of the rising wall 5B, similar to the recess 28 of the substrate 5A. The other side of the protruding portion 29 is made to escape.

One side end of the cover plate 5C, which is butted against and connected via the hinge part 25, forms slopes 33a and 33b with an inclination angle of approximately 45°, respectively, as shown in FIG. When the cover plate 5C is closed, it is made parallel to the substrate 5A.

In such a configuration, when storing the cassette 4 in the cassette storage case 1, first store the cassette 4 in the dedicated cassette case 5.
will be stored in.

To store the cassette in the dedicated cassette case 5, keep the cover plate 5C open as shown in FIG.
The protrusion 29 provided on the lower surface side of the cassette 4 is fitted into the cylinders 26A and 26B of A, and the protrusion 29 is inserted into the recess 2 of the substrate 5A.
8 and place the cassette 4 on the substrate 5A.

Then, when the cover plate 5c is closed and the pair of small diameter cylindrical bodies 31A and 31B are fitted into the inner holes 27 of the cylindrical bodies 26A and 26B from each reel hole 12 of the cassette 4, the cassette 4 is inserted into the dedicated cassette case 5. It will be stored.

Next, when storing the dedicated cassette case 5 containing the cassette 4 in the cassette storage case 1, as shown in FIG. A pair of protrusions 9
may be fitted into the inner holes 27 of the cylinders 26A, 26B from below.

In this case, as described above, the outer diameter of the cylindrical portion 9A of the protrusion 9 is slightly larger than the inner diameter of the inner hole 27, so the cylindrical portion 9A is press-fitted into the inner hole 27, but the cylindrical portion 9A is as shown in FIG. As shown in b, it has a slot 10, and since it is elastically deformed inward, it fits securely into the inner hole 27, and after that, it is pressed against the peripheral wall of the inner hole 27 by the stable elastic restoring force of the cylindrical portion 9A itself. The dedicated cassette case 5 is prevented from coming off by withstanding repeated use and maintaining elasticity.

In addition, by not directly fitting the cassette 4 into the cylindrical portion 9A but through the dedicated cassette case 5, the shape, dimensions, precision, etc. of each part necessary for locking with stable elastic force can be improved. It is easier to meet the conditions.

Further, when the cylindrical portion 9A is completely fitted into the inner hole 27, the substrate 5
The protrusion 30 provided on the lower surface of A is the bottom plate 6 of the case body 2.
However, a gap is provided between the lower surface of the substrate 5A and the inner surface of the bottom plate 6A by the large diameter portion 9B (see FIG. 5) of the projection 9.

Therefore, the dedicated cassette case 5 can be stored horizontally on the inner surface of the bottom plate 6A by the convex part 30 and the large diameter part 9B, and if the dedicated cassette case 5 is lifted by inserting a finger into the gap, the cylindrical part 9A The inner hole 27 can be easily disengaged, and the dedicated cassette case 25 can be easily taken out.

Furthermore, the cassette 4 can be directly taken out by opening the cover plate 5C of the dedicated cassette case 25 without taking out the dedicated cassette case 25.

Note that the case where the exclusive cassette case 5 is stored in each cassette storage section of the lid body 3 is exactly the same as described above.

In this case as well, the protrusion 23 and the dedicated cassette case 5
Due to the dimensions of the inner hole 27, the dedicated cassette case 5 can be securely fixed, so when opening and closing the lid 3 or handling the storage case with the lid open, the dedicated cassette case 5
The cassette storage case 1 does not fall off from the protrusion 23 and is reliably stored within the lid 3 of the cassette storage case 1.

Thus, cassette storage case 1 having such a configuration
According to the above, since five dedicated cassettes 5 can be stored in each of the case body 2 and the lid body 3 in a two-dimensional manner, the storage case 1 itself can be made thin and its volume can be reduced.

In addition, the space in the height direction in which the storage case 1 is stored can be reduced, and since the dedicated cassette case 5 is stored horizontally, unlike the conventional vertical direction, it is easy to take out the storage case 1 and put it in the storage case 1. The storage operation is easy, and the dedicated cassette case 5 can be stored in either direction, improving handling.

In addition, since each dedicated cassette case 5 is fixed by the protrusions 9 and 23, it is securely stored and held with stable elastic force, and there is almost no risk of it falling off during handling, and it can be stored in the lid body 3. There is no problem when inserting the device, you can feel the insertion, and it does not move even when it vibrates or is transported.

Furthermore, since the cassette 4 is stored through the dedicated cassette case 5, restrictions on design due to the cassette 4 made according to standard specifications are alleviated, and the degree of freedom in design inside the cassette storage case is increased.

Although the above embodiment describes the case where the case body 2 and the lid 3 are molded simultaneously and connected by a pair of hinge parts 20, this invention is not limited to this. Of course, the lid body 3 may be removably locked to the case body 2 by a plurality of hook-shaped engaging pieces and locking portions.

Further, in the above embodiment, the large diameter portions 9 of the protrusions 9, 23
B and the convex portion 30 of the dedicated cassette case 5 are configured so that the dedicated cassette case 5 can be stored horizontally inside the case body and the lid, but this invention is not limited to this. A concave portion corresponding to the convex portion 30 may be provided on the inner surface of the device, or a convex portion may be provided at an appropriate location so that the device can be stored in a horizontal state.

In addition, a trapezoidal recess 2B provided in the dedicated cassette case 5,
If an opening is provided in place of 32, the convex portion 30 of the dedicated cassette case 5 will be eliminated, making it easier to store the dedicated cassette case 5 in a horizontal state within the case body.

Furthermore, this invention is not limited to the above-mentioned embodiment and can be modified in various ways. For example, the locking piece 15 may be provided on the case body 2 side, the locking portion 14 may be provided on the lid body 3 side, or the well-known blow molding method may be used. Therefore, the bottom plate 6A of the case body 2 and the top plate 1 of the lid body 3
9A may have a double wall structure to increase its strength or to increase or decrease the number of dedicated cassette cases that can be housed therein.

As explained above, the cassette storage case according to this invention stores a plurality of dedicated cassette cases in a flat manner inside the case, and the protrusions provided on the inner surface of the case are tightly and elastically fitted into the holes of the dedicated cassette cases. Since the dedicated cassette case is fixed by fitting the cassette case, the volume of the cassette storage case itself can be reduced, and it can be easily stored even in a place where space in the height direction is limited.

In addition, since the dedicated cassette case is stored flat, it is easy to take out and store it, and the dedicated cassette case can be securely fixed in place with stable locking force, preventing it from falling off or moving. The practical effects are very great, such as the fact that there is no problem with the design and there is a high degree of freedom in designing the inside of the cassette storage case.
