A rotation direction of the shaft and the gear connected to the first one-way bearing 141 and the second one-way bearing 142 will be described. The first one-way bearing 141 and the second one-way bearing 142 are coupled to the shaft and the gear so that the rock state and the idle state act in opposite directions.

That is, the first one-way bearing 141 is a guide roller rotating shaft 131 by the friction force between the guide roller 63 and the bill when separating the bills to separate the bills loaded on the pickup roller 61 one by one It becomes the drive side. In this case, the guide roller 63 should be prevented from rotating in the banknote conveyance direction to prevent the separation of the two sheets of banknotes. Therefore, the first one-way bearing is locked when the banknote is separated (rock) to prevent rotation of the guide roller 63 in the banknote transfer direction, the guide roller 63 to prevent the wear of the guide roller 63 When rotating in the reverse direction of the guide roller in the opposite direction to the bill transfer direction, the first one-way bearing 141 is in an idle state, and only the guide roller rotating shaft 131 rotates in the outer housing 132. do.

Meanwhile, the second one-way bearing 142 blocks the rotational force of the driving motor from being transmitted to the guide roller 63 when the banknote is separated, and transfers the guide roller 63 to the guide roller 63 to prevent uneven wear of the guide roller 63. In the case of rotating in the reverse direction of the guide roller in the opposite direction, the rotational force of the driving motor should be transmitted to the guide roller 63. Therefore, the second one-way bearing 142 is in an idle state when the banknote is separated and becomes a rock state when the guide roller is rotated in the reverse rotation direction.
