Is being guided to. An adhesive table 10 is arranged below the connection table 9, and an adhesive tape 12 is guided from the adhesive tape supply reel 11 to the adhesive table 10.

A degaussing head 13 composed of a permanent magnet is arranged between the guide rollers 7 and 8 on the upstream side of the tape collecting reel 4. Reference numeral 14 denotes a tape cassette continuous supply device, which supplies a large number of tape cassettes 1 to a position below the connection table 9 as shown by arrows in the drawing.

2 to 5 are views for explaining the magnetic tape continuous recovery method of the present invention having the above-mentioned structure, which will be described with reference to FIG.

In FIG. 1, when the tape cassette 1 is set at the lower position of the connection table 9, a pair of tape pull-out arms 15 and 15 are exposed from the inside of the apparatus main body as shown in FIG. 2A. As shown by the arrow, the magnetic tape 3 is pulled out from the tape cassette 1 so as to contact the surface of the connection table 9. Next, the pair of tape reels 2a and 2b are rotated by a driving means (not shown), and the magnetic tape 3 and the connecting portion J of the leader tape 16a for connecting the magnetic tape 3 and the tape reel 2a are located at the central position of the connection table 9. Adjust to come to. At this time, an optical sensor is used to detect the connecting portion J.

The connection position J between the magnetic tape 3 and the leader tape 16a is 5 to 20 mm from the central position of the connection table 9.
2B, as shown in FIG. 2B, the cutter 17 is exposed from the inside of the main body of the apparatus, moves upward, and disconnects the connecting portion J.

FIG. 2C is a view of the connection table 9 as viewed from below. The connection table 9 is a fixed table 9a.
And a moving table 9b that moves in the direction of the arrow with respect to the fixed table 9a.
The magnetic tape 3 or the leader tape 16b (described later) on one tape reel 2b side of the tape cassette 1 is guided, and the leader tape 16a and the tape recovery reel 4 on the other tape reel 2a side of the tape cassette 1 are guided to the moving table 9b. The side recovery tape 6a (including the magnetic tape 3 described later) is guided. By moving the moving table 9b with respect to the fixed table 9a, the two tapes 6a and 16a on the other tape reel side are selectively flushed with the tape 3 on one tape reel side. Is configured.

In FIG. 2C, the end of the recovery tape 6a of the tape recovery reel 4 is guided by the moving table 9b. In addition, the end of the magnetic tape 3 cut in FIG. 2B is guided to the fixed table 9a, and the end of the leader tape 16a is guided to the moving table 9b.

Next, when the moving table 9b is moved in the direction of the arrow from the state of FIG. 2C, the ends of the magnetic tape 3 and the recovery tape 6a are flush with each other, as shown in FIG. 3A. It Then, the adhesive tape 12 on the adhesive table 10
Is cut by a cutter (not shown), the adhesive table 10 moves toward the connection table 9 as shown in FIG. 3 (B), and the end portions of the magnetic tape 3 and the recovery tape 6a as shown in FIG. 3 (C). Are adhered by the adhesive tape 12.

As described above, the magnetic tape 3 of the tape cassette 1 is the recovery tape 6 of the magnetic tape recovery reel 4.
When the magnetic tape recovery reel 4 is connected in the direction of the arrow in FIG. 1 in this state as shown in FIG.
The magnetic tape 3 of the tape cassette 1 is wound around the magnetic tape collecting reel 4 and collected. At this time, the information recorded on the magnetic tape 3 is erased by the degaussing head 13 and the confidentiality is secured.

As the winding of the magnetic tape 3 progresses, the magnetic tape 3 and the other leader tape 16 of the tape cassette 1
The connection portion J with b is 5 to 2 from the central position of the connection table 9.
When it reaches the position of 0 mm, the magnetic tape recovery reel 4 is stopped. Next, the cutter 17 emerges from the inside of the main body of the apparatus, moves upward, and disconnects the connecting portion J. FIG. 4B shows the state of the connection table 9 at this time.

When the moving table 9b is moved in the direction of the arrow in the state of FIG. 4B, the leader tape 16b connected to both tape reels 2a and 2b of the tape cassette 1 as shown in FIG. 5A. And 16a are flush with each other, and the adhesive tape 12 on the adhesive table 10 is cut by a cutter (not shown), and the adhesive table 10 moves toward the connection table 9 as shown in FIG. C)
As shown in, the ends of the leader tapes 16b and 16a are bonded by the adhesive tape 12. Here, the magnetic tape 3 on the moving table 9b functions as a recovery tape for recovering the magnetic tape of the next tape cassette.

The tape cassette 1 to which the leader tapes 16b and 16a are connected is discharged from the apparatus main body and used as a recycled product, and a new magnetic tape is wound by a conventionally known tape winding device. Then, the next tape cassette 1 is set at the lower position of the connection table 9 by the tape cassette continuous supply device 14, and by repeating the above process, the tape collecting reel 4 can store several tens of tape cassettes. The magnetic tape is continuously wound and collected.

When the magnetic tape 3 wound on the tape collecting reel 4 becomes full, the end portion of the leader tape 6b of the adjacent tape collecting reel 5 shown in FIG. The magnetic tape of several tens of tape cassettes can be continuously collected on the tape collecting reel 5 by being guided to the connection table 9 via 8 and repeating the above process.
