Description

[Detailed description of the invention] (a) Technical field of the invention The present invention relates to a magnetic tape storage case, and particularly to a magnetic tape storage case that can easily store magnetic tape wound on a reel without loosening the winding. It is.

(b) Background of the Technology Magnetic tape devices are widely used as information file devices in electronic computer systems and as high-speed input/output devices. On the other hand, when storing or transporting magnetic tape, which is now used in large quantities as an information storage medium in such devices, it is necessary to protect the magnetic tape from dust from the outside world and to keep it in the best condition so that it does not loosen or wrinkle. For example, a magnetic tape housing case made of plastic or the like is used so that the magnetic tape can be maintained at a high temperature.

(c) Prior Art and Problems The conventional magnetic tape storage case described above generally consists of a storage case body and an upper cover having a simple rotational opening/closing lock mechanism. When storing the magnetic tape in the storage case body, use a holder made of sponge or the like between the reels corresponding to the starting end of the magnetic tape to prevent the magnetic tape wound on the reel from becoming loose. The tape is then inserted into the storage case body with the starting end fixed, and an upper cover is placed over it, and the tape is further locked by a rotating opening/closing lock mechanism for storage or transportation.

However, as mentioned above, the holder used to prevent the magnetic tape from loosening when storing the magnetic tape in the storage case does not work as the magnetic tape is repeatedly removed from the storage case and attached to and removed from the magnetic tape device. Because magnetic tapes often get lost, it is not always possible to wrap them securely and store them in the storage case, and it is extremely difficult to keep a spare holder on hand to prevent tapes from loosening. The problem was that it was difficult to handle.

(d) Purpose of the invention In order to solve the above-mentioned conventional drawbacks, the present invention provides a method to prevent the winding of the magnetic tape from loosening when the magnetic tape is housed in a storage case, the top cover is covered, and the lock is locked by a rotating opening/closing lock mechanism. At the same time, it is an object of the present invention to provide a magnetic tape storage case that is easy to handle.

(e) Structure of the invention According to the invention, in a magnetic tape storage case consisting of a storage case body for storing a magnetic tape and an upper cover having an opening/closing lock mechanism for the storage case body, A tape holding device is provided at a plurality of predetermined locations on the peripheral wall from the center of the storage case body, each connected by a spring-loaded connecting wire having an engagement device on the center side, and each of the engagement devices and the above-mentioned engagement devices are provided on the upper cover side. This is achieved by providing a magnetic tape storage case characterized in that an engaging hook is provided so as to be interlocked with an opening/closing lock mechanism.

(f) Embodiments of the invention Examples of the invention will be described below in detail with reference to the drawings.

FIG. 1 is a top view showing an embodiment of the storage case body of the magnetic tape storage case according to the present invention, FIG. 2 is a sectional view of the main part along the -' cutting line shown in FIG. A top view showing one embodiment of the upper cover that pairs with the storage case main body shown in FIG. 1, and FIG.
FIG. 2 is a cross-sectional view of the main part taken along the -' cutting line shown in the figure. First, as shown in FIGS. 1 and 2, the storage case body 1 of the magnetic tape storage case according to the present invention is made of plastic, for example, and has a plurality of predetermined locations on the peripheral wall from the center side. In this embodiment, connecting wires 4 made of piano wire or the like each having an engaging member 2 on the center side are installed at four locations.
A tape holding device 5 made of, for example, a sponge and having a spring 3 connected thereto is disposed to be guided by a guide groove 6 provided in the bottom plate portion of the housing case body 1. By pulling each of the above-mentioned engaging tools 2 in the direction of arrow A shown in the figure, the tape holding tool 5 connected by the connecting wire 4 can be moved inward of the storage case body 1. . 7 is the upper cover 11
This is the locking part for the opening/closing lock.

On the other hand, the upper cover 11 paired with the storage case body 1 has a rotary opening/closing lock mechanism 12 in the center, as shown in FIGS. 3 and 4. The opening/closing lock mechanism is related to a recess at the center of the upper surface of the upper cover 11, and includes a rotary lock knob 13 provided in particular, and a lock for opening/closing on the storage case body 1 side, which is connected to this and disposed inside. The mounting portion 14 includes a plurality of engaging hooks 15 that engage with the portion 7 and a hook 16 that engages with each of the engaging tools 2 on the housing case main body 1 as shown in the drawing.

Now, a magnetic tape (not shown) is housed in the housing case main body 1 configured as described above, and the upper cover 11 is covered as in the conventional case, and the rotary lock knob 13 is moved in the direction shown by the arrow B shown in FIG. Rotate to
When locked, the hook 16 on the top cover 11 side
The respective engaging tools 2 on the storage case main body 1 side that are engaged with the storage case body 1 are simultaneously pulled in the direction of arrow A shown in FIG. In this embodiment, the circumferential surface of the magnetic tape is pressed from all sides, and as a result, the magnetic tape can be easily prevented from becoming loose. Also, when taking out the magnetic tape from the storage case, use the rotary lock knob 1 on the top cover 11 side, contrary to the storage operation described above.
By turning 3 in the opposite direction to the original direction, remove the upper cover 11.
At the same time as the opening/closing lock is released, each of the tape holding devices 5 pressing against the magnetic tape surface is separated from the magnetic tape surface by the spring 3, so that it can be easily taken out.

(g) Effect of the invention As is clear from the above explanation, according to the magnetic tape storage case according to the invention, the magnetic tape is stored inside the storage case body, and the upper cover is covered and locked using the rotary opening/closing lock knob. ,
Since the magnetic tape is configured to prevent the winding from loosening, the conventional inconvenience of losing the winding loosening prevention holder while repeatedly taking the magnetic tape in and out of the storage case is eliminated. It has the advantage that it can be easily stored without unwinding. Therefore, by applying it to this type of magnetic tape storage case, handling becomes extremely convenient, which is practically effective.
