FIG. 2 shows a cross section showing a state in which a large magnetic tape cassette 1 and a small magnetic tape cassette 2 are stored in the case. It shows a state where many cases are arranged.

In each of the drawings, a storage case 10 is formed by injection molding or the like.
And a lid 16 having one side integrally connected to one side in the longitudinal direction of the case main body 12 via a connecting piece 14.

The case main body 12 has a bottom plate 18 formed in a rectangular shape in accordance with the external dimensions of the magnetic tape cassette 1.
And a standing wall 20 formed in a frame shape with four corners raised one step on the periphery on the bottom plate 18 and fitted with the outer periphery of the magnetic tape cassette 1. A locking recess 22 for fixing to 16 is formed.

Both longitudinal sides of the connecting piece 14 are integrally connected to the bottom plate 18 and the lid 16 of the case main body 12 through thin hinges 24 so as to be foldable and deployable. The lid 16 is formed upright on the top plate 26 hinged to the connecting piece 14 and on the inside of the top plate 26, that is, around the surface facing the case body 12.
An outer wall 28 of a U-shaped frame fitted to the outer portion of the tape cassette 1 is provided. The height of the outer wall 26 and the width of the connecting piece 3 correspond to the thickness of the magnetic tape cassette 1.

A pair of locking projections 30 are provided on both sides of the outer wall 28 on the inner side of the rotation end so as to resiliently engage with the locking recesses 22 and hold the lid closed. In addition, inside the outer wall 28, a plurality of reinforcing ribs 32 projecting from the top of the upright wall 20 are protrudingly provided. Ribs 34 for holding the folded shape, which abut against the rear surfaces of both ends of the piece 14, are integrally raised.

In addition to the above general configuration, the present invention provides:
At the center of the inner bottom surface of the bottom plate 18 of the case main body 12, a shallow groove-shaped fitting recess 36 having a shape and an area corresponding to the external dimensions of the small magnetic tape cassette 2 is formed. In the center position in the direction
A positioning boss 38 common to the magnetic tape cassettes 1 and 2 is provided protruding from the fourth side.

The fitting recess 36 is formed to be about half the thickness of the general portion of the bottom plate 18 so that when the small magnetic tape cassette 2 is mounted on the case body 12, It fits into the fitting recess 36 and is positioned. If a sufficient thickness cannot be ensured, or if the thickness is too small to fit the small magnetic tape cassette 2 and the strength cannot be ensured, the bottom surface of the bottom plate 18 is adjusted according to the depth of the fitting recess 36. Of course, the side may be protruded.

The boss 38 is opened on the back side of each of the magnetic tape cassettes 1 and 2 and protrudes from a positioning hole (not shown) with respect to the loading position of the video camera. Even if the sizes are different as described above, the positions of the positioning holes are shared, and the above bosses 38 are also protruded in the case 10 in accordance with this, so that the positioning holes can be positioned and mounted on the case body 12. I have to.

Further, a leaf spring piece 40 protrudes from the center of the inner surface of the top plate 26 of the lid 10. The leaf spring piece 40 is made of an elastic resin or metal and bulges inwardly with both ends being fixed ends. Due to its elasticity, as shown in FIGS. 2 (a) and 2 (b), The upper surfaces of the magnetic tape cassettes 1 and 2 are pressed and fixed.

In FIG. 2, the direction of the leaf spring piece 40 is shown differently from FIGS. This is only changed in direction for understanding the cross-sectional shape, but the fixing function is the same regardless of the direction in which it is formed.

2 and 3, reference numeral 42 denotes a label holder made of a transparent resin sheet disposed from the center of the surface of the top plate 26 of the lid 16 to the back of the connecting piece 14, and both ends thereof are welded 44, respectively. Fixed by
A label can be inserted between the label holder 42 and the lid 16 and the connecting piece 14.

The label holder 42 may be arranged from the surface of the bottom plate 18 of the case main body 12 to the back of the connecting piece 14, or may be arranged around the connecting piece 14 from the bottom plate 18 and arranged on the top plate 16 side. Of course, it is possible.

In the above configuration, when the large magnetic tape cassette 1 is stored in the case main body 12 with the tape draw-out side 1c positioned forward, in the unfolded state shown in FIG. 20. The large magnetic tape cassette 1 is positioned by the boss 38 being fitted into the positioning hole with the bottom surface of the large magnetic tape cassette 1 attached to the bottom plate 18.

Thereafter, when the lid 16 is rotated toward the case main body 12 through both the thin hinges 24, the lid 16 is folded while the connecting piece 14 is raised, and when the lid is completely closed, the lid 16 is closed as shown in FIG.
As shown in (a), the outer periphery of the upright wall 20 is folded into a book shape while being fitted to the outer wall 28 by the connecting piece 14, and the large magnetic tape cassette 1 can be stored in a fixed state.

In this closed state, the locking projection 30 resiliently engages with the locking concave portion 22 and is kept closed unless an external force in the opening direction is applied. Also, the leaf spring piece 4
Numeral 0 makes elastic contact with the upper surface of the magnetic tape cassette 1 and presses the magnetic tape cassette 1 against the bottom plate 18 to suppress the play of the magnetic tape cassette 1 due to a slight gap formed between the magnetic tape cassette 1 and the top plate 26.

When the small magnetic tape cassette 2 is to be stored in the case body 12, the tape pull-out side 2c is positioned at the front side and is fitted into the fitting recess 36. Boss 38
Are fitted into the positioning holes to perform positioning.

Thereafter, when the lid 16 is closed, as shown in FIG. 2 (b), the leaf spring piece 40 elastically contacts the upper surface of the magnetic tape cassette 2 and presses it against the bottom plate 18 to prevent it from dropping out of the fitting groove 36. To prevent.

Therefore, even if the cases 10 accommodating the magnetic tape cassettes 2 are arranged vertically in a horizontal line as shown in FIG. 3, the magnetic tape cassettes 2 are fixed at predetermined positions in the case 10. Can be stored in the state.

Although the leaf spring piece 40 has a structure in which both ends are fixed, one end may be fixed in a cantilever manner. Furthermore,
The leaf spring piece 40 may be formed integrally with the case 10. Further, in order to externally check whether the magnetic tape cassette 1 or the magnetic tape cassette 2 is housed in the case 10, the case 10 is made in two colors of different colors, so that the judgment can be made by color. Alternatively, the determination can be made only by label display.

If the magnetic tape cassette to be stored has three types of sizes, the fitting recess 36 has a size corresponding to the size.
One is formed concentrically, and the number of fitting recesses 36 is set according to the number of magnetic tape cassettes to be stored.

[0031]

As is apparent from the above description, in the case for storing the magnetic tape cassette according to the present invention,
Although the external dimensions are the same as those of the large magnetic tape cassette, the small magnetic tape cassette can also be accommodated in a fixed state, so that it is possible to prevent problems in organizing due to a difference in dimensions.
