  • Publication number: 20230312277
    Abstract: A paper sheet storage container capable of accurately taking out paper sheets one-by-one. A paper sheet group is held by a paper sheet placing table and holding members, while the paper sheet placing table is being biased upward by an elastic member so that the position of an uppermost paper sheet of the paper sheet group placed on the paper sheet placing table is substantially the same position as the positions of holes through which air flows. In this state, in the paper sheet storage container, air is blown from a side to the uppermost paper sheet of the paper sheet group placed on the paper sheet placing table thereby allowing the uppermost paper sheet to be brought into a state in which the vicinity of the center thereof has been raised.
