Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved invention mainly directed to a so-called book case type cassette storage case, and its object is to improve a novel cassette storage case that can rapidly connect a plurality of cassette storage cases of this type in sequence. We also aim to propose reasonable measures.

Hereinafter, a specific example of a cassette storage case embodying the present invention will be explained with reference to the drawings.

First, the general structure of this embodiment is as shown in FIGS. 1 and 2, including an outer case 1 made of a resin molded product, and an inner case 2 also made of a resin molded product that stores a tape cassette.
The outer case 1 is adapted to be placed over the inner case 2 by a rotational operation.

That is, the inner case 2 can be inserted into and removed from the outer case 1 from the closed state shown in FIG. 1 to the open state shown in FIG. 2, or from the state shown in FIG. 2 to the state shown in FIG. The inner case 2 is provided with an engager 10 [10a, 10b, 10c, 10d) that prevents the reel hub from rotating blindly when the tape cassette is stored.
The rotational blind movement of the reel hub is prevented when the inner case 2 is inserted into the outer case 1 and the state shown in FIG. 1 is achieved.

Note that the entire storage case is indicated by the symbol C.

Next, each part of the storage case C will be explained. As shown in FIGS. 1 and 2, the outer case 1 has a vertically long shape with the left side and top open, and its front plate 3a and rear plate 3b. As shown in the figure, the inner case 2 is formed into a symmetrical L-shape to facilitate removal of the inner case 2.

On the other hand, the inner case 2 has a rectangular shape with an opening at its upper end surface in the longitudinal direction in the state shown in FIG. (See Figure 3), the cassette 4 is stored with the front window facing upward.

Therefore, recesses 6a and 6b having widths and depths corresponding to the protrusions 4a and 4b of the cassette 4 are formed in the front plate 5a and rear plate 5b of the inner case 2, respectively, so that when the cassette 4 is stored in the case. are each concave portion 6a, 6b and protrusion portion 4a,
4b are in contact with each other.

The inner case 2 also has a reel shaft insertion hole 7 for the cassette 4.
For example, a tapered hexagonal engager 101:10a as shown in FIG.
~10d], and these engagers 10 are attached to one end of each of four arcuate elastic pieces 11 (11a to 11d) made of resin or metal thin plates that are biased outward of the case 3, and are usually In the state shown in FIG. 4, the elastic piece 11a.

11b is bent outward (the same goes for the other elastic pieces),
Therefore, in this state, although the tips of the engaging elements 10a and 10b are somewhat protruding into the interior of the inner case 2, when the cassette 4 is inserted, the engaging elements 10a to 10d are placed on both sides of the insertion holes 7a and 7b. The department will start to get involved.

In addition, the front plate 5a and rear plate 5b of the inner case 2 have four
Bow-shaped long holes 12 (12a-12d) are formed to attach the elastic pieces 11a-11d, and in this example, the other end of each elastic piece 11a-11d is inserted into each long hole as shown in FIG. 1
A slit is provided at the edge of 2 to insert and fix.

The inner case 2 configured in this manner is inserted into and removed from the outer case 1 by rotating the outer case 1 as described above.
At the corner position on one end side is a husbandutsuko, in this case, bottle 8a.
, 8b are provided protrudingly, and on the inner surface of the front plate 3a of the outer case 1 are guide grooves 9a for guiding the bottles 8a, 8b.
9b are formed respectively.

-The guide groove 9a that guides the bottle 8a is the front plate 3a.
The guide groove 9b corresponding to the bottle 8b is formed substantially horizontally from the left side near the lower edge of the front plate to a predetermined position.

Therefore, if the bins 8a and 8b are engaged with the guide grooves 9a and 9b, respectively, there is an advantage that the sliding of each bin allows the outer case 1 and the inner case 2 to rotate relative to each other within a small space. Moreover, in the open state as shown in FIG. 2, the bottle 8a acts as a stopper at the upper end of the guide groove 9a, which helps to strengthen the case against unreasonable outward movements.

In addition, when the cassette 4 is stored in the closed state as shown in FIG. 1, the engaging elements 10a facing each other as shown in FIG.
, 10bC10c, 10d are not shown] are the insertion holes 7a,
7b, and the left and right sliding hubs 4' are prevented from rotating blindly.

That is, this is because when the outer case 1 is placed over the inner case 2, the elastic pieces 11 are mutually bent inward.

The engaging members 10a to 10d may be substantially cross-shaped protrusions as shown in FIG. 7, or may have various other shapes.

Furthermore, the shapes of the elastic pieces 11a to 11d, their mounting structures, etc. can be set in various ways.

Incidentally, the cassette storage case CK is provided with a means for arranging a large number of cassettes in parallel and sequentially connecting them.

A specific example will be described below. In this embodiment, a short dovetail groove 13 is formed at the upper position near the right side of the front plate 3a of the outer case 1, and at the lower center position including the L-shaped projecting portion. 14 are provided parallel to the upper and lower sides of the case, and dovetail pieces (not shown) that engage with the dovetail grooves 13 and 14, respectively, are formed at corresponding positions on the rear plate 3b. It is in the state shown in Figure 1.

By sliding the separate case C against the front or rear surface of the cassette storage case C from right to left in the same direction, the dovetail grooves and dovetail pieces of both sides are engaged with each other, and the final Specifically, both cassette storage cases C are connected with their outlines aligned.

In other words, by such an operation, a large number of cassette storage cases C are connected in parallel, and the direction of the above-mentioned sliding contact refers to one relative direction.

However, what should be noted in the example is that the pair of upper and lower dovetail grooves 13 and 14 are made as short as possible than the width of the front plate 3a (the same applies to the dovetail pieces).

In other words, this is a measure to perform the connection and separation operations almost instantaneously, and is a clever improvement over the inconvenience of having to slide the two connected objects across their entire surfaces, which was the case in the past. .

FIG. 5 is an enlarged perspective view showing the engagement structure between the upper dovetail groove 13 and the dovetail piece of the separate case. Recess 1
3a, and a well-known dovetail piece 15 is formed on the rear plate 3b of the separate case, and by inserting this dovetail piece 15 from the recess 13b into the engaging part 13a, a dovetail engagement state is achieved. The front plate 3a and the rear plate 3b, specifically the two cassette storage cases C, are approximately closely connected, and the sliding stroke required for the connection is l.

Note that the lower dovetail groove 14 shown in FIGS. 1 and 2
The dovetail groove 13 is also substantially the same as the dovetail groove 13, and is denoted by the reference numeral 14a.

14b indicates an engaging portion and a positioning recess.

The above is an embodiment of a book booth type cassette storage case to which the present invention is applied, but in short, the gist of the present invention is to mainly connect a large number of such storage cases sequentially in parallel, or to connect the connected bodies individually. consists in the means of separating the
The functions and effects of the present invention are already clear, and therefore the practical benefits obtained are extremely large.
