Next, the width sensor 463 of the width storage processing means 404 detects the width k in the wide portion 452.

As a result, the horizontal transfer motor 472 is started under the control of the grip processing control unit 520, and the placement plate 469 and the like are moved in the direction a.
That is, it is transferred to the wide portion 452 side.

As a result, the width k is placed on the band placement plate 469.

After this, the horizontal transfer motor 472 rotates in reverse, and the belt placing plate 46
Return 9 to its original position.

Next, the vertical transfer motor 483 is started, and the pressing support plate 48
6 and the band pressing piece 487 are lowered vertically downward. As a result, the band pressing piece 487 presses the width k onto the band placing plate 469. Thereafter, the vertical transfer motor 483 is reversely rotated to return the band pressing piece 487 to its original position.

Next, under the control of the grip processing control section 520, the accommodation and transfer motor 474 is started, and the rotating arm 475 and the protruding pin 47 are started.
Rotate 5a. As a result, the slide lever 476
The band pushing pawl 478 also slides along the long groove 469a, and transfers the bandage k pressed onto the band placement plate 469 into the bandage storage box 462. The transferred purse is stored in the purse storage box 462.

On the other hand, the sheet C from which the width k has been removed by the band removing means 403 described above is further conveyed by the grasping and conveying means 401, and eventually the two clamping members 493 of the clamping and rotating means 405
, 496.

This paper sheet C is detected by the paper sheet sensor 504,
As a result, the gripping and rotating motor 501 starts rotating in the direction of arrow α1 shown in FIG. 8 under the control of the gripping processing control section 520. Then, as shown in FIG. 9(a), the arm 502 and the engagement pin 503 also rotate in the α1 direction, whereby the bent piece 496a engaged with the engagement pin 503
At the same time, the upper holding member 496 rotates in the α2 direction opposite to the α1 direction using the protruding support piece 494 as a fulcrum. As a result, the paper sheet C is held between the holding pieces 498 and 499 provided on both holding members 493 and 496.

This state is shown in FIG. 9(b).

Furthermore, when the motor 501 rotates in the α1 direction, the engagement pin 503 is now in contact with the end of the elongated hole 496b, so the upper holding member 496 can no longer rotate in the α2 direction, and the lower side It rotates together with the clamping member 493 in the α1 direction as shown in FIG. 9(C).

Eventually, the paper sheets C held by both the holding members 493 and 496 are scraped off by the scraping member 510 of the scraping means 406.
By rotating the scraping member 510 in the β direction, a large number of sheets C are squeezed and residual bands remaining between the sheets C are scraped off.

Thereafter, the motor 501 rotates in the reverse direction to return the paper sheet C to its original position, and further releases the sandwiched state of the paper sheet C by an operation opposite to that described above.

Thereafter, the paper sheet C is sent to the paper sheet cutting means 407 by a pusher (not shown), where it is turned into paper sheets one by one and sent to the inspection device 6.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention.

[Effects of the Invention] According to the present invention described in detail above, with the above configuration, the belt can be cut and removed from paper sheets in a bundle.
It is possible to provide a band removal device for paper sheet bundles, which allows the scraping member to reliably scrape out residual bands that cannot be completely removed, and ensures reliability in band removal processing.
