Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to an auto-loading magnetic tape cartridge, in particular, when the magnetic tape is completely wound into the tape reel and the tape entrance/exit of the cartridge is closed, The present invention relates to a magnetic tape cartridge that is easy to handle and prevents the magnetic tape from rewinding.

(2) Prior Art and Problems In recent years, many magnetic tapes with autoloading cartridges have been used to facilitate the handling of magnetic tapes.

Such a magnetic tape with a cartridge can be mounted in a magnetic tape device with the cartridge attached to the tape reel, and the automatic magnetic tape loading operation (auto threading) can be performed reliably.

In addition, the combination of reel and cartridge can protect the magnetic tape from external dust, etc. without storing it in a container, which has an excellent operational advantage.
Since there is no magnetic tape fixing means to prevent the rolled magnetic tape from loosening, it is difficult to transport a magnetic tape with a cartridge without fixing the magnetic tape from a storage to a computer room, etc. The wound magnetic tape becomes loose due to vibrations and shocks during transportation, and must be re-wound each time it is used, which wastes time and damages the magnetic tape itself. However, there were drawbacks in handling.

(3) Purpose of the invention In order to eliminate the above-mentioned drawbacks, the present invention provides a novel magnetic tape loosening prevention means that can easily fix or release the magnetic tape winding surface in conjunction with opening/closing operations of the tape entrance/exit of the cartridge. The purpose of the present invention is to provide a magnetic tape cartridge with a high degree of flexibility.

(4) Structure of the invention To be distantly related to the above object, the present invention proposes an auto-loading magnetic tape inlet/outlet opening/closing mechanism which is mounted around the outer periphery of a tape reel wound with magnetic tape so as to cover the magnetic tape. In the tape cartridge, regarding each end of the integrated tape cover and the magnetic tape cartridge main body that move relatively when the tape inlet/outlet is opened/closed when the tape inlet/outlet is opened/closed, a leaf spring-shaped tape retainer for holding down the magnetic tape is provided on the inner surface of the integrated part of the tape cover. is fixed at one end thereof, and is movably interposed between the tape cover and the tape retainer on the inner surface of the corresponding portion of the magnetic tape cartridge main body, and the tape entrance is closed by the closing operation of the tape entrance opening/closing mechanism. The present invention is characterized in that a retainer pushing up member is provided corresponding to the fixed end side of the tape retainer and having a tip part that pushes up the tape retainer so as to press it against the magnetic tape.

(5) Embodiments of the invention Preferred embodiments of the invention will now be described in detail with reference to the drawings.

FIG. 1 is a sectional view of essential parts of an embodiment of a magnetic tape cartridge according to the present invention.

1 is a cartridge main body of the present invention which is mounted on a tape reel 13 wound with a magnetic tape 12; 2 and 3 are cartridge opening/closing ends that widen the circumference of the cartridge main body 1; A cartridge opening/closing mechanism 4 is attached as shown in FIG.

The cartridge opening/closing mechanism 4 is brought into contact with the opening/closing end 3 by reversing the opening/closing rail μ5 in the direction of the arrow 6, and is led out into a shape extending from the one opening/closing end 2. The leading end of the tape cover unit 7 closes a tape inlet/outlet 8 provided in the cartridge body 1.

As shown in the partially enlarged plan view of FIG. 2 and the cross-sectional view of FIG. As shown, a magnetic tape loosening prevention means, which is a feature of the present invention, is provided.

That is, as the magnetic tape loosening prevention means, a leaf spring made of rubber or sponge added to the tape cover integral 7, or a leaf spring-shaped tape retainer 9 made of flexible polyamide resin, polyethylene, etc., is used.
is fixed with a screw 10 to support one end of the tape retainer 9 as shown in the figure, and a retainer pusher is implanted in the cartridge body 1 between the tape retainer 9 and the tape cover unit 7 so as to span the tape cover unit 7. A raising member 11 is interposed.

Then, by moving the tape cover unit 7 in the direction of the arrow, the retainer push-up member 11 enters into the vicinity of the screw 10 of the tape retainer 9, and as a result,
The pressing surface of the other end of the tape retainer 9 is pushed up to press and hold the opposing surface of the magnetic tape 12.

1. Therefore, when a magnetic tape in which a magnetic tape cartridge configured as described above is mounted in a ring is mounted in an automatic loading type magnetic tape device and the magnetic tape is loaded into the device, as shown in FIG. One opening/closing end 2 is separated from the other opening/closing end 3 of the cartridge main body 1 by operating the opening/closing lever 5 of the cartridge opening/closing mechanism 4, the tape entrance/exit 8 opens, and the magnetic tape 12 is automatically removed from the tape entrance/exit 8. is brought out.

Further, after use, the magnetic tape 12 is completely wound into the magnetic tape cartridge so that the opening/closing lever 5 of the cartridge opening/closing mechanism 4
is reversed in the direction of the arrow 6, and as shown in FIG. When the tip is closed, the retainer push-up member 11 moves in conjunction with the screw 10 fixing direction of the tape retainer 9 to push up the tape retainer 9 and automatically press and hold the wound magnetic tape 12 surface. It takes shape.

Therefore, even if the cartridge-attached magnetic tape in this state is removed from the apparatus and transported to a storage shelf or warehouse, the magnetic tape 12 is prevented from loosening, and handling efficiency is improved.

(6) Effects of the invention As is clear from the above explanation, according to the magnetic tape cartridge of the invention, the magnetic tape can be wound into the cartridge and the tape entrance/exit can be closed without major changes to the structure of the magnetic tape cartridge. At the same time, a locking retainer is automatically added to the magnetic tape,
On the other hand, when the tape entrance/exit port is opened, the locking retainer is automatically separated from the magnetic tape surface, so that the magnetic tape using the magnetic tape cartridge is attached to the magnetic tape device. In the state in which the tape is not loosened, tape loosening is prevented, and the conventional inconveniences associated with loosening of the magnetic tape are eliminated, so that the ease of handling the magnetic tape is significantly improved.

Therefore, it is extremely advantageous to apply this type of magnetic tape cartridge.
