ABSTRACT:
A paper sheet supplying apparatus comprises a transfer guide unit, a register unit and a paper sheet sending-out unit. The supplying apparatus supplies a paper sheet through the transfer guide unit to the register unit from the paper sheet sending-out unit. The guide unit has a straight portion and a curved portion, and guides the paper sheet from the sending-out unit to the register unit. An inwardly indented curved surface of the curved portion, on which the paper sheet is in contact, has a plurality of ribs separated from each other. Not more than three ribs of the plurality of ribs are arranged in a center region of the curved surface in the transfer direction, and the remaining ribs of the plurality of ribs are arranged in each side region located proximate the center region. Each of the ribs in the center region has a first height, and each rib in each side region has a height which is smaller than the first height.
