PROBLEM TO BE SOLVED: To improve reliability.SOLUTION: A roller transportation part 20 connects an upper side shaft 36U receiving reaction force FRD generated according to contact pressure FCU which applies energy to a driven roller 56 toward a drive roller 54 and a lower side shaft 36D receiving a reaction force FRU generated according to contact pressure FCD which applies energy to a driven roller 36 toward the drive roller 56 by a support component 50. Thereby, on adjacent paper bill transportation passages 48U and 48L, the reaction force FRD and the FRU which make an upper guide 45 and a lower guide 46 bend are canceled. |
