A pusher plate stacking bin apparatus is provided for a valuable media depository. The apparatus comprising a pusher plate driven by a rack and pinion apparatus to stack a media item that is in a final position within the apparatus onto a media stacking platform. The media item is urged into the final position such that a trailing edge of the media item overhangs and rests on a fixed media guide and such that a leading edge of the media item overhangs and rests on a hinged media guide with a bottom surface of the media item elevated above the media stacking platform. The rack and pinion apparatus drives the plate past the media guides causing the hinged media guide to drop and the media item to fold along the leading edge as the media item is stacked onto the platform.

In the paper feeding roller, a shaft body has a cantilever structure supported at one end, and an elastic layer includes a supported end and a free end on both ends along a rotation axis, wherein an outer diameter of the free end in a cross section orthogonal to the rotational axis is greater than that of the supported end, and an area including the free end has a widened bottom part having an outer diameter which widens in a linear or inner convex manner approaching the free end along the rotation axis. The paper feeding device includes a feed roller rotationally driven and conveying paper, and a retard roller pressed against the feed roller, affixed with a torque limiter, and suppressing double feeding of paper. At least one of the feed roller and the retard roller is formed as the paper feeding roller.

To reduce, at the time of sheet replenishment, breakage of a floating regulation member that regulates floating of a sheet floated by air blowing in a sheet storage apparatus that loosen stored sheets by means of air blowing. Air is blown to sheets stored in a storage part to loosen the sheets. One of a pair of side regulation members for regulating both ends of the sheets stored in the storage part has a floating regulation member for regulating floating of a sheet floated by means of air blowing. The floating regulation member is configured to be turnable in a sheet stacking direction about a rotation axis provided to one of the side regulation members on the side at which the floating regulation member is provided. A load applied to the floating regulation member differs between when the floating regulation member is turned upward and when it is turned downward.

Provided is a sheet storage apparatus including: an apparatus body; a sheet storage section; a top cover; a sheet feeding section; a restricting cursor; a blowing device; a sheet holding-down member; and a moving mechanism. The sheet storage section includes a sheet supply port, and a sheet stacking portion. The top cover is pivotable to an opening position and to a closing position. The blowing device includes a fan and a vent. The sheet holding-down member includes a restricting piece. The moving mechanism is coupled to the sheet holding-down member, moves the sheet holding-down member to a restricting position by coming into contact with the top cover under a state in which the top cover has come to the closing position, and moves the sheet holding-down member to a retracted position by separating from the top cover when the top cover is moved to the opening position.

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.

A media feeding apparatus includes a media mounting section, a first feed roller, a media pressing section for pressing media sheets against the first feed roller, and a pressing force adjuster for adjusting the pressing force of the media pressing section. The controller sets the pressing force of the media pressing section to first pressing force and drives the first feed roller and the second feed roller in a forward rotation direction, and in a case in which the first detector detects a passage of a leading edge of the media sheet and the second detector detects no passage of the leading edge of the media sheet after predetermined first set time has passed, the controller continues the rotation of the first feed roller and the second feed roller with second pressing force of the media pressing section greater than or equal to the first pressing force.

A medium regulating component for use in a medium feeding device feeding sheet media accommodated in an accommodating unit, the component for regulating excessive floating of a medium accommodated in the accommodating unit, the component includes: a regulating member protruding in a horizontal direction from an accommodating unit periphery and contacting the floating medium; a holding member holding the regulating member in a non-contact state with the medium; a first rotating shaft rotatably supporting the regulating member relative to the holding member; and a second rotating shaft rotatably supporting the holding member relative to the accommodating unit, in which when the regulating member receives a pressing force from below in a gravitational direction, rotates about the first rotating shaft in a state where movement of the holding member is suppressed, and pushes the holding member to rotate about the second rotating shaft.
