The feeding roller 17 is rotatably driven at a rotation speed suitable for feeding the banknote 11 by being rotatably attached to a rotary shaft 18 which is rotationally driven via a drive motor and a speed reduction mechanism. Similarly, the auxiliary roller 16 is also rotatably driven at the same speed as that of the feeding roller 17 by being rotatably mounted on a rotary shaft 19 which is rotationally driven via a drive motor and a speed reduction mechanism.

By the way, a friction roller 20 for single-sheet feeding control is provided opposite to the feeding facing surface below the feeding roller 17 corresponding to the feeding portion.

The friction roller 20 is provided in a pair of left and right corresponding to both the feeding rollers 17 and 17, the entire outer peripheral surface similarly has a material having a high friction coefficient such as a rubber material, and in the axial direction of the roller outer peripheral surface, The uneven roller surface 20a corresponding to the uneven surface is formed in a non-contact manner with the uneven roller surface 17a of the feeding roller 17 described above.

Then, the banknote 11 in the initial stage of being fed out from the storage section 12 is guided between the corresponding surfaces of the concave-convex roller surfaces 17a, 20a, and one banknote 11 is controlled to be fed out at the initial passage time.

In this case, the separating action between the concavo-convex corresponding surfaces is performed by curving the bill 11 guided between the concavo-convex roller surfaces 17a, 20a by concavo-convexly deforming it into a corrugated shape and with respect to bills guided in a state of two-ply stacking or the like. To give a separating force to control one sheet feeding.

Of the auxiliary roller 16 and the feeding roller based on the feeding signal of
When 17 is driven to rotate synchronously, the bills 11 that have been fed by the rollers 16 and 17 are fed in the feeding direction, and the feeding roller 17 and the friction roller 20 arranged at the feeding portion are controlled to feed one sheet. It is passed through between the parts and delivered. At this time, in the second step 72, when the paper jam detection sensor S detects the bills to be fed out, the feeding timer is started, and in the third step 73, the bills 11 pass through both rollers 17 and 20 and the paper is fed. When the jam detection sensor S is turned off, it is determined that the normal feeding is performed, and the next bill 11 is fed. However, in this case, when the paper jam detection sensor S continues to detect the paper jam banknote 11a and the feeding timer times out in the fourth step 74, it is determined that a paper jam has occurred at this feeding portion, and Perform the paper jam removal process. First, in the fifth step 75, the rotation of the auxiliary roller drive motor M2 is stopped so that the next stored bill will not be fed out during this paper jam removal processing. Then, in the sixth step 76, the friction roller 20 is rotationally driven in the feeding direction in the seventh step 77 while the rotational driving of the feeding roller 17 is maintained. As a result, the jammed paper money 11a will
The discharge processing is performed by performing the forced feeding operation by sandwiching and feeding between 7,20. At this time, in the eighth step 78, the discharge timer for the paper jam banknote 11a is started, and in the ninth step 79, the paper jam detection sensor S detects
