  • Patent number: 10518993
    Abstract: In a paper sheet storing apparatus housed in a paper sheet handling apparatus, a storage part stores paper sheets. An ejection port ejects a paper sheet of the paper sheets stored in the storage part. A first roller is arranged near the ejection port, and is rotated in a predetermined direction by transmission of rotation caused by drive of a drive shaft so as to send out the paper sheet from the ejection port. A driven shaft is rotated in the predetermined direction following the rotation of the first roller. A second roller is arranged in a position farther from the ejection port than a first roller, and is rotated in the predetermined direction by transmission of rotation of the driven shaft so as to sequentially feed, to the first roller, the paper sheets from a paper sheet positioned in a lowest layer among the paper sheets.
