Note that the lowermost second bill 21b receives a feeding force from the bill 21a, but its leading end contacts the gate roller 36, so that the feeding is stopped.

Therefore, even if small banknotes are mixed in the stored banknotes 21, they are preliminarily conveyed by the conveyor belts 23, 23 and then fed out by the increased feeding force of the pickup rollers 32, 32 and the feed rollers 35, 35. Thus, it is possible to reliably carry out one sheet from the lowermost banknote 21a.

The bill 21 thus fed out is taken over by the external pinch rollers 38, 38 and is conveyed to the next step. Further, when the stored bills 21 are sequentially fed out and the sensor 39 detects that the stored bills 21 are exhausted, the CPU 40 stops the driving of the motor 42 (step n2) and ends the feeding process.
