Description

[Detailed description of the invention]

The present invention relates to a tape cassette storage case for storing a tape cassette wound with tapes such as a magnetic tape.

2. Description of the Related Art Conventionally, tape cassettes have been handled in storage cases for sale and storage, and the case is provided with a lid that can be freely opened and closed at a hinge portion in a rectangular case body that stores a magnetic tape cassette. Transparent case is used.

The conventional storage case is made of a polystyrene resin transparent material (hereinafter referred to as GP-PS), so that when the storage case is dropped, the storage case is often cracked, cracked or chipped. High impact resin material such as high impact polystyrene resin material (hereinafter HI
-PS), the entire case was made invisible, and the tape cassette contained in the case became invisible and the product value was reduced. The purpose of the present invention is to eliminate these conventional disadvantages accurately, improve the impact resistance around the storage case, reduce cracking and chipping due to dropping, and make the tape cassette inside the case easy. It is an object of the present invention to provide a tape cassette storage case that can be easily viewed and has a good appearance.

SUMMARY OF THE INVENTION The present invention provides a case body and a case body for accommodating a tape cassette.
A tape cassette storage case comprising a lid body pivotally attached to the hinge body so as to be openable and closable and having a pair of hub rotation preventing projections inside the case body or the lid body. Characterized in that a first synthetic resin material excellent in quality and the other parts are formed of a transparent second synthetic resin material, and the lid is formed of the second synthetic resin material. Case.

[0005]

In the case of the present invention, when the magnetic tape cassette is housed in the case main body 1, the hub rotation preventing projections 9, 9 are fitted into the hub holes of the tape cassette so that the positions thereof can be regulated and held. Most of the tape cassette contained in the case can be seen from the portion of the second synthetic resin material and the lid, and even if the case is accidentally dropped, the periphery of the case body has high impact resistance. Because it is a resin material, it can be used safely without damage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. A transparent or translucent case main body 1 capable of accommodating a tape cassette is provided with a lid 3 which is hinged on a hinge 2 so as to be freely opened and closed. In a tape cassette storage case provided with a pair of hub rotation preventing projections 9, 9 inside the case main body 1, a part around the case main body 1, for example, a part of a side wall and a bottom wall, is formed by two-color molding means. First synthetic resin material 4 having excellent impact resistance, for example, HI-PS (high impact polystyrene resin), ABS (acrylonitrile / butadiene / styrene copolymer resin), ACS (chlorinated polyethylene / acrylonitrile / styrene copolymer) Polymerized resin), AA
S (acrylate / styrene / acrylonitrile copolymer resin) or the like, and other parts of the case body 1 and all parts of the lid 3
A tape cassette formed of a transparent second synthetic resin material 5, for example, a resin selected from GP-PS (polystyrene resin), AS (acrylonitrile / styrene copolymer resin), PMMA (polymethyl methacrylate resin), etc. A storage case is configured. In this case, the hinge portion 2 is configured such that a pin is provided on the case body 1 side, and a bearing portion of a pin hole that can be fitted to the pin is provided on the lid 3 side. It may be provided in reverse, and it is configured to be easily engaged with the fitting concave portion 11 and the convex portion 12 on the relative sliding wall surface of the case body 1 and the lid 3.
Further, the case main body 1 is configured so that the lid 3 can be easily opened.
Alternatively, a concave portion 11 and / or a finger portion 6 of a convex portion may be attached to any one or both of the lids 3. In addition, on the inner surfaces of the case main body 1 and the lid 3, concave portions 7, 8 into which a head house of a tape cassette is fitted are formed as necessary. Further, the case body 1 has at least one side of an upright wall surface of the case body 1 as an opening, and a side wall extending up to the opening is erected on a bottom wall. 2 and each other by deploying the cover 3 openably to the opening and position frame-like side wall 3 ₁ provided on the 3 side lid, are to facilitate insertion holding the tape cassette. In addition, a pair of hub rotation preventing projections 9, 9
Is provided on the case body 1 side, but may be provided on the lid body 3 side.

In the examples shown in FIGS. 4 and 5, in a case having the same structure as in FIG. 1, a plate-like base 41 made of HI-PS resin material is provided on a part of the bottom wall as the case main body _1. If, there is to have the rotation preventing protrusion 9, a plate-shaped base portion 4 ₁ of the peripheral side wall portion of the case body 1 HI-P
It is effective from the viewpoint of manufacturing to form the structure in a state of being connected to the S resin material 4.

[0008]

According to the present invention, the periphery of the case body is formed of a first synthetic resin material having excellent impact resistance, and the other portions are formed of a transparent second synthetic resin material. By using the synthetic resin material of No.2, the shock resistance around the case is improved, cracks and chips can be reduced even if the tape cassette storage case is accidentally dropped, and the tape cassette can be taken in and out of the case. Smooth and easy operation, significantly improved tape cassette holding in the case, improved case appearance, safe handling of the tape cassette, and visibility of the tape cassette in the case And the commercial value of the case is increased, and there is a practical effect that the case can be made inexpensive.
