In this type of device, for example, as shown in FIG. Using the urging force, the bottom plate 6 pushes upward and presses it against the feeding force output roll 7, and the rotation of this feeding Q-luer causes the paper sheet 4 to be fed between the curved base 1 and the conveyance roll 2. At the same time, the paper sheets 4 are transported to a predetermined position by the rotation of the transport rolls 2.

On the other hand, the mechanism shown in FIG. 5 is one in which a mechanical member 9 is provided facing a fixed base 8 so as to be movable up and down.
