Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette housing case suitable for use in housing a tape cassette for a video tape recorder, for example.

[0002]

2. Description of the Related Art For example, a tape cassette used in a broadcasting station is stored by being stored in a plastic storage case when not in use.

Conventionally, as shown in FIGS. 6, 7, 8 (A) and 8 (B), a tape cassette storage case of this type has been adopted.

This will be described with reference to FIG. 1. In FIG. 1, reference numeral 1 is a box for accommodating a tape cassette, and a case body 2 having a cassette insertion / removal opening 2a and an integral body of the case body 2. The cassette insertion / removal opening 2 provided
and a lid 3 that opens and closes a, and is entirely formed of a synthetic resin material such as polypropylene.

The case body 2 of the box body 1 is provided integrally with one bottom plate 4 for holding the tape cassette K and the edge portion of the bottom plate 4, and four front, rear, left and right sides in which a part of the tape cassette K faces the inside thereof. It is formed by the wall plates 5-8.

On the bottom plate 4 of the case body 2, cylindrical protrusions 9 and 10 for positioning the tape cassette K are arranged in parallel.

Further, of the wall plates 5 to 8 of the case body 2, the front wall plate 5 has two locking holes 5 opening on the front and back surfaces.
a and 5b are provided.

On the other hand, the lid body 3 of the box body 1 includes the bottom plate 4
Further, it is formed by one ceiling plate 11 corresponding to each of the wall plates 5 to 8 and four front, rear, left and right wall plates 12 to 15. The lid 3 is provided with a recess 3a for storing a card, which is open on the surface and extends from the central portion in the width direction of the ceiling plate 11 to the central portion in the width direction of the rear wall plate 13.

The ceiling plate 11 of the lid 3 is provided with locking pieces 11a and 11b which can be locked in the locking holes 5a and 5b, respectively.

The rear wall plate 13 of the wall plates 12 to 15 of the lid 3 is connected to the ceiling plate 11 and the bottom plate 4 via hinges 16 and 17, respectively.

Each of the hinges 16 and 17 is formed of a synthetic resin hinge extending in the longitudinal direction of the case by setting the size smaller than the thickness of the case.

[0012]

By the way, in the conventional tape cassette storage case, the wall plates 5 to 8 of the case body 2 are erected at a position apart from the frontmost edge of the bottom plate 4. Therefore, the bottom plate 4 is warped after the case is molded, and a gap is formed between the bottom plate 4 and the wall plates 12 to 15. As a result, dust easily enters the box body 1,
There is a problem in that it adheres to the tape (not shown) of the tape cassette K and adversely affects recording and reproduction.

The present invention has been made in view of such circumstances, and it is possible to prevent dust from entering the case, which may adversely affect the recording / reproducing of the tape of the tape cassette. No tape cassette storage case is provided.

[0014]

In the tape cassette storage case according to the present invention, the connecting plate and the case body are provided with a rising wall facing the outer edge of the wall portion of the lid in the case closed state.

[0015]

In the present invention, even if a gap is formed between the case body and the lid when the case is closed, this gap is covered by the rising wall.

[0016]

Embodiments of the present invention will be described in detail below with reference to embodiments shown in the drawings.

1 and 2 are perspective views showing the opened and closed states of the tape cassette storage case according to the present invention, and FIGS. 3A and 3B are sectional views taken along the line aa of FIG. bb
It is a line sectional view.

In FIG. 1, reference numeral 31 is a box for accommodating a tape cassette, which is a case main body 32 having a cassette insertion / extraction opening 32a, and the cassette insertion / extraction opening 32a provided integrally with the case main body 32. It is composed of a lid 33 and is entirely formed of a synthetic resin material such as polypropylene.

The case main body 32 of the box body 31 forms a bottom plate 34 for holding the tape cassette K and a space E integrally provided at an edge portion of the bottom plate 34 for accommodating a part of the tape cassette K. It is formed by four wall plates 35 to 38.

On the bottom plate 34 of the case main body 32, cylindrical protrusions 39 and 40 for positioning the tape cassette K are arranged in parallel.

The front wall plate 35 and the left and right wall plates 3 are provided at the front left, right, and three edges of the bottom plate 34 in the case closed state.
A first rising wall 41, which is U-shaped in a plan view and has an inner side surface facing the outer end edges of the front left and right wall plates, is integrally provided at 7, 38, which will be described later. At the tip of the first rising wall 41, inclined surfaces 41a and 41b having a slope that decreases toward the tip are formed.

Further, the wall plates 35 to 3 of the case body 32.
Of the eight, the front wall plate 35 is provided with two locking holes 35a and 35b which are open to the front and back surfaces.

On the other hand, the lid 33 of the box 31 includes a ceiling plate 4 corresponding to the bottom plate 34 and the wall plates 35 to 38.
2 and the front, rear, left and right wall plates 43 to 46. The lid 33 is provided with a recess 33a for storing a card, which is open on the surface and extends from the central portion in the width direction of the ceiling plate 42 to the central portion in the width direction of the rear wall plate 44.

The ceiling body 42 of the lid 33 has locking pieces 42a, 4 which can be locked in the locking holes 35a, 35b, respectively.
2b is provided.

The rear wall plate 44 among the wall plates 43 to 46 of the lid 33 is provided on the ceiling plate 42 and the bottom plate 34 via hinges 47 and 48, respectively, and the rear wall plate 36.
It is composed of a connecting plate corresponding to.

At the left and right end edges of the rear wall plate 44, the second rising wall 4 having inner side surfaces facing the rear end edges of the left wall plate 45 and the right wall plate 46 in the case closed state.
9, 50 are integrally provided. At the tip of the second rising wall 49, inclined surfaces 49a and 50a that can be engaged with the inclined surfaces 41a and 41b are formed.

The hinges 47 and 48 are made of synthetic resin material and extend in the longitudinal direction of the case by setting the dimensions smaller than the case thickness.

In the tape cassette storage case thus constructed, even if a gap is formed between the case body 32 and the lid 33 when the case is closed, that is, when the cassette insertion / extraction opening 32a is closed by the ceiling plate 42, This gap is the first
It can be covered by the rising wall 41 and the second rising walls 49, 50. At this time, the wall plate 43 of the lid 33
46 faces the wall plates 35 to 38 of the case body 32.

Therefore, in this embodiment, the box 3
Since it is possible to prevent dust from entering the inside of 1,
It is possible to prevent adhesion of the tape cassette K to the tape (not shown).

In the present embodiment, the rear end faces of the left wall plate 45 and the right wall plate 46 of the lid 33 face the left and right side edges of the rear wall plate 44 and the front wall plate when the case is closed. 43,
The lower end surfaces of the left wall plate 45 and the right wall plate 46 are the case body 3
2 has a structure facing the bottom plate 34, the present invention is not limited to this, and FIGS.
As shown in FIG. 5, the case body 32 may be provided with recesses 61 to 63 in which the wall edge of the lid 33 faces the inside when the case is closed. In this case, the intrusion of dust into the box body 31 is further effective. Can be blocked.

It goes without saying that the material of the box body in the present invention is not particularly limited.

[0032]

As described above, according to the present invention, the connecting plate and the case body are provided with the rising wall facing the outer edge of the wall portion of the lid body in the case closed state. Even if a gap is formed between the lid and the lid, the gap is covered by the rising wall.

Therefore, since it is possible to prevent dust from entering the case, there is no adverse effect on the tape of the tape cassette in recording and reproducing.
