The operation of the above configuration will be described.
FIG. 7 is an enlarged explanatory view showing an operation state of each tongue piece according to the first embodiment.

  When the rotation of the reverse roller shaft 10a is stopped, as shown in FIG. 7A, the first and second tongue piece rollers 21 and 23 have outer peripheral surfaces other than the installation range of the hub portions 21a and 23a. The first and second tongue pieces 22, 24 are accommodated in a state of being bent between the stopper 26 and the hub portions 21 a, 23 a toward the carry-in / out port 3, and the first and second tongues are accommodated. The pieces 22 and 24 are stopped in a state where they are retracted to the outside of the transport path 16 and the storage space of the banknote storage 1.

At this time, the position detection sensor 14 detects the detected portion 13 a of the positioning member 13.
From the state shown in FIG. 7A, when the rotational force of the drive gear 11 driven by a drive source (not shown) for the accumulation operation is transmitted to the reverse roller shaft 10a via the one-way clutch 12, the reverse roller shaft 10a is 7B, the first and second tongue pieces 22 and 24 of the first and second tongue piece rollers 21 and 23 rotate in the direction of the arrow, A part of the second tongue piece 24 starts to protrude into the conveyance path 16.

  Then, as shown in FIG. 7C, the first and second tongue pieces 22 and 24 at the head of the first and second tongue piece rollers 21 and 23 in the accumulation rotation direction release the restraint by the stopper 26. Due to its elasticity, the original shape, that is, the first tongue piece 22 is restored to a radial shape and the second tongue piece 24 is restored to a curved state, and is discharged into the storage space by the feed roller 5 and the reverse roller 10. Hit the trailing edge of the banknote P.

At this time, since the tip of the second tongue piece 24 is positioned 45 degrees forward in the stacking rotation direction, the tip of the second tongue piece 24 is rotated 45 degrees ahead, and the tip is the banknote first. The rear end of P is hit, and then the front end of the first tongue piece 22 hits the rear end of the bill P.
Similarly, each subsequent tongue piece strikes the rear end of the banknote P, knocks down the rear end of the banknote P, and draws it toward the front plate 2a while pressing it against the banknote P that has been stacked. The banknotes P are aligned.

Then, after the first tongue piece 22 at the tail of the first tongue piece roller 21 finishes hitting the bill P, the reverse roller shaft 10 a further rotates, and the position detection sensor 14 detects the detected portion 13 a of the positioning member 13. Is detected, the drive source is stopped and the rotation of the reverse roller shaft 10a is stopped.
At this time, the first and second tongue pieces 22 and 24 of the first and second tongue piece rollers 21 and 23 are placed between the stopper 26 and the hub portions 21a and 23a shown in FIG. Return to containment and stop.

  Thus, in the stacking operation of the present embodiment, when the leading second tongue piece 24 of the second tongue piece roller 23 is released from the restraint by the stopper 26, its tip is advanced 45 degrees. Until the first tongue piece 22 at the tail of the first tongue piece roller 21 finishes hitting the banknote P, it expands in an operating range of substantially 225 degrees exceeding the setting range of 180 degrees, The banknotes P can be struck down and aligned, and the banknotes P can be accurately stacked even with a partial tongue piece roller in which tongue pieces are partially provided.

If the thickness of the root portion of the second tongue piece 24 of the second tongue piece roller 23 and the degree of bending by the bent portion 24b are changed, the restraint by the stopper 26 of the second tongue piece 24 is released. The restoring force can be increased to increase the restoring speed, and it is possible to perform the preceding rotation at an angle exceeding 45 degrees.
Hereinafter, the separating and feeding operation of the banknote P and the stacking operation by the banknote separating and stacking mechanism 28 of the present embodiment will be described.

Each operation described below is executed by a control unit (not shown) by a program stored in a storage unit (not shown).
At the time of separating and feeding out the bill P, the reverse roller shaft 10a stops at the angular position where the detected portion 13a of the positioning member 13 fixed thereto is detected by the position detection sensor 14, and the first and second tongue pieces 22, 24 is retracted from the conveyance path 16 in a state where it does not protrude into the conveyance path 16 shown in FIG.

The roller 6 is pressed with a predetermined pressing force.
The control unit that presses the uppermost banknote P against the picker roller 6 rotates the feed roller 5 in the feeding rotation direction indicated by an arrow in FIG. 8, and transmits the rotation to the picker roller 6 by the drive belt 9. Is rotated in the same direction as the feed roller 5, that is, in the feeding rotation direction, and the bills P are fed out from the stage 4 and conveyed to the feed roller 5 provided at the carry-in / out port 3.

At this time, since the rotation of the reverse roller shaft 10a is not transmitted by the idling of the one-way clutch 12, the reverse roller 10 and the first and second tongue pieces rollers 21 and 23 do not rotate, and the first and second tongue pieces are not rotated. The retracted state of 22 and 24 is maintained.
The banknotes P conveyed to the feed roller 5 side are separated into one sheet by the reverse roller 10 that has stopped rotating, and are fed to the conveyance path 16 by the feed roller 5 that rotates in the feeding rotation direction, and are conveyed by a conveyance means (not shown). It will be transported.

When stacking the bills P, the control unit that has confirmed that the position detection sensor 14 has detected the detected portion 13 a of the positioning member 13 lowers the stage 4, and moves the top of the bills P stacked on the stage 4. 9 is stopped when the upper surface detection sensor 19 no longer detects the bill P, and the feed roller 5 is rotated in the direction indicated by the arrow A in FIG.
At this time, rotation is transmitted to the reverse roller shaft 10a via the one-way clutch 12, and the reverse roller 10 and the first and second tongue piece rollers 21 and 23 rotate in the accumulation rotation direction indicated by an arrow B in FIG. As described with reference to FIG. 7, the first and second tongue pieces 22, 24 of the first and second tongue piece rollers 21, 23 are deployed in a range of substantially 225 degrees.
