Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protective member for a magnetic tape cassette that protects the magnetic tape cassette from damage, mechanical impact, and the like.

In recent years, the use of magnetic tape cassettes has increased significantly due to the spread of magnetic recorders, especially magnetic tape recorders that use magnetic chip cassettes. Nowadays, most cars are equipped with cassette tapes, so the magnetic tape is even more powerful! The use of Rikishichitto is increasing. Generally, such a cassette is supplied housed in a case. This case acts as a dust bag/paddle and also prevents the cassette knob from rotating. In addition, it is desirable that the cassette be housed within the case to protect the cassette from mechanical shock.Furthermore, the case prevents the magnetic tape housed within the cassette from becoming sagging. When the cassette is transported to a certain location, or when the cassette is placed inside a moving car, without the above anti-rotation function, the vibration of the cassette will cause the cassette to rotate and wrap around the magnetic tape. Sagging may occur. When the cassette was played with the magnetic tape winding slack, the rotation of the hub caused the magnetic tenor to suddenly become stretched, causing a large tension to act on the magnetic tape and causing it to break. or extended).

The cassette case, which has many advantages as described above, is generally larger than the cassette itself. This is because the cassette case must be thick enough to accommodate the thickest part of the cassette, such as the trapezoidal protrusion formed adjacent to the tape transport opening of the cassette. The cassette case is 1
．． A rotatable housing is provided inside the case as a mechanism to facilitate the removal of the cassette.In addition, a one-cassette case generally carries the contents of the cassette, a piece of paper with information written on it, along with the cassette. It is stored inside the case.

As a result, the cassette case becomes even larger than the cassette.In this way, the cassette case is also larger than the cassette itself. The ninth drawback is that it requires a large amount of space. On the other hand, a label is generally attached to each cassette, and this label contains almost all of the information written on the paper stored in the cassette case. This label alone is enough for the purchaser to know the contents of the cassette. As a result, buyers tend to easily throw away cassette cases that are large and cumbersome to put in and take out cassettes, and often store cassettes by themselves. Cassettes are easily susceptible to damage that could be easily avoided if only the size of the cassette case and the inconvenience of putting in and taking out the cassette case were tolerated.

The present invention has been made in consideration of this point, and an object of the present invention is to provide a protective member for a magnetic tape cassette, which has a smaller lid than conventional cassette cases and can be easily attached to the cassette.

According to the magnetic tape cassette protection member of the present invention, which achieves the above object, it has an opening that can accommodate the protrusion formed adjacent to the tape transport opening of the cassette, and its length and width. are the length and width of the cassette
A hanging plate that is formed to be very short, a shelf part that grinds from the inside of the hanging plate to close the opening for the chi l transformer/-), and a hanging plate that is detachably attached to one side of the cassette. Installation includes means and.

It is desirable that the thickness of the protrusion is approximately equal to the height of the protrusion from both sides of the cassette.
An opening is formed in which the protrusion can be accommodated. [The best way to attach the plate is to have a pair of O-engaging holes formed at the sharpening end of the shelf, and these protrusions widen by a distance approximately equal to the thickness of the cassette. The respective projections, which are preferably spaced apart from the hanging plate, are aligned so as to face each other with the hanging plate, and each projection, together with the hanging plate and the ledge, has a shape in its cross section. A U-shaped groove is formed, which groove is configured to receive the end of the cassette.

The magnetic tape cassette protection member can also include a key/arm means that protrudes from the inner surface of the hanging plate and engages with at least one of the hub holes of the cassette to prevent rotation of the cassette. It is preferable that the inner Δ1 means is arranged along the longitudinal direction of the folding plate and includes a plurality of nine protrusions.

In addition, if the protective member for the magnetic tape cassette is made of a transparent material, the label affixed to the cassette can be easily viewed from above the protective member, making it much more difficult to use than a set case. In addition, if you store a cassette with this protective member attached and a 9-inch cassette stored in the cassette case in the same space, you can store far more cassettes. can be easily attached and detached. Nevertheless, this protective member can protect the cassette from mechanical shocks, scratches, etc. in the same way as the cassette case.
