At this time, the claw portion 10a of the hooking member 10 moves from the bundled position of the strip a to a position that is sufficient to pull out the strip a from the end of the sheet p. It's starting to move.

Further, the single sheet take-out section 2 of the paper sheet processing apparatus is configured as follows. That is, as shown in FIG. 2, in the vicinity of the end of the sheet bundle conveyance path 4, the stacked paper sheets P conveyed from above the floor 6 according to the movement of the pair of conveying pins 8, 8 are placed. A supporting take-out backup 17 is arranged. This take-out back-up 17 is located slightly below the floor 6 so that the paper sheets P can be smoothly transferred from the floor 6 without being caught, and is also raised by a mechanism (not shown) to perform vacuum suction. The take-out side end of the uppermost sheet P is brought into contact with the take-out roller 18.

Further, a detection lever 19 is arranged above the take-out backup 17, and a proximity switch (not shown) is arranged so that the optical axis passes near the detection lever 19. ... is detected, and the take-out roller 18
The take-out backup 17 is always controlled so that it is at a convenient position for take-out.

Furthermore, when all the paper sheets P on the take-out backup 17 are taken out, the lower end of the detection lever 19 falls into the through hole 20 formed in the take-out backup 17, blocking the optical axis of the nearby switch, and The take-out backup 17 is lowered to the lowest position in response to a signal from the switch.

Note that 21 shown in FIG. 2 is a band collection box.

Next, the operation of the above embodiment will be explained. first,
A bundle of paper sheets P' is sequentially supplied to the paper bundle conveyance path 4 from a paper sheet bundle supply section (not shown) disposed at the starting end thereof. As shown in FIG. 1, the paper sheets P' are fed between the pairs of transfer pins 8, 8 and 8, 8 with both ends in the longitudinal direction protruding from both edges of the floor 6. At this time, if the band a is not at the center in the longitudinal direction but is shifted to one end as shown in Figure 1, bend the paper sheet so that the end of the band a that is not wrapped around is clamped. It is supplied in a state corresponding to the mechanism 9 side. However, the paper sheet bundle conveyance path 4

The paper sheets P are then transferred onto the take-out backup 17, where they are taken out one by one starting from the topmost paper sheet P.

On the other hand, when the unstrapped paper sheets P... are supplied to the sheet take-out section 2, the following sheet bundle P' stops facing the unstripping device 5.

Then, when a signal indicating that all the paper sheets P have been taken out from the single sheet take-out section 2 is sent, the pair of transfer pins 8, 8, . . . are simultaneously moved one pitch intermittently.

By repeating the above operations, the stacked paper sheets P bound by the band a are automatically unbundled and then sequentially supplied to the single-sheet takeout section 2.

In the above-mentioned embodiment, only the band pulling member 10 is moved in the direction perpendicular to the winding direction of the band a to pull out the band a. The sheet bending mechanism 9 may also be moved in the opposite direction at the same time, or the same objective can be achieved by moving only the sheet bending mechanism 9.

It goes without saying that various other modifications can be made without departing from the gist of the present invention.
