In a paper sheet storing apparatus (10) housed in a paper sheet handling apparatus (1), a storage part (16) stores paper sheets. An ejection port (14) ejects a paper sheet of the paper sheets stored in the storage part (16). A first roller (17b-1) is arranged near the ejection port (14), and is rotated in a predetermined direction by transmission of rotation caused by drive of a drive shaft (17b-3) so as to send out the paper sheet stored in the storage part (16) from the ejection port (14). A driven shaft (17a-3) is rotated in the predetermined direction following the rotation of the first roller (17b-1) in the predetermined direction caused by the transmission of the driving rotation of the drive shaft (17b-3). A second roller (17b-1) is arranged in a position farther from the ejection port (14) than a position in which the first roller (17a-1) is arranged, and is rotated in the predetermined direction by transmission of rotation of the driven shaft (17a-3) in the predetermined direction so as to sequentially feed, to the first roller (17b-1), the paper sheets stored in the storage part (16) from a paper sheet positioned in a lowest layer among the paper sheets.
