A paper sheet storing/feeding device (e.g., escrow unit 40) includes a rotary member (e.g., drum 42) to an outer peripheral surface of which one end of a belt-shaped winding member (e.g., tapes 90, 92, 94) that winds a plurality of paper sheets one by one is connected, and a guiding unit (80, 85) that guides a paper sheet to prevent the paper sheet from sandwiching the winding member from both sides when the paper sheet is fed from the rotary member by unwinding the winding member from the rotary member.
