Abstract: The purpose of the present invention is to reduce the size of an automatic teller machine (ATM), in which the height of a banknote deposit/withdrawal opening is in a lower position, while maintaining banknote storage capacity. A banknote handling device handles bank notes, and the banknote handling device has a first conveyance roller that conveys bank notes and that changes the conveyance direction of the banknotes between a conveyance path in which the banknotes are conveyed from the deposit/withdrawal unit along the vertical direction and a conveyance path in which the banknotes are conveyed in the horizontal direction. The distance between a delivery unit and a first conveyance unit is shorter than the length of the banknotes in the conveyance direction. Due to this configuration, it is possible to reduce the height of the banknote handling device and to reduce the size of the banknote handling device or the ATM.
