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.

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.

A device for separating printing paper sheets comprises a base part and an obstruction element. The base part defines a printing paper accommodating cavity. A deforming mechanism is provided to make sure a middle part of the printing paper sheets can be arched and two edges can get close to the bottom of the printing paper accommodating cavity. The obstruction element is arranged with a middle access portion in cooperation with the deforming mechanism, and on two sides of the middle access portion is arranged with blocking portions through which only one printing paper sheet can pass at a time. The device for separating printing paper sheets makes more than one printing paper sheet that may be transmitted at a time during the transmission of the printing paper sheets. A printer achieves smooth transmission of printing paper sheets and alleviates problems such as downtime and failure of the printer.

A sheet conveying device includes a sheet stacker, an air blower, a guide, and a holder. The sheet stacker stacks sheets. The air blower blows air to the sheets on the sheet stacker. The guide is disposed facing an uppermost sheet of the sheets on the sheet stacker. The holder holds the guide and has a groove along which the guide is inserted. The groove has a plurality of direction switching portions at each of which the guide changes a direction of movement when the groove receives the guide.

A media processing device includes: a hopper for supporting a stack of media units (e.g. cards), the hopper including (i) a gate wall configured to abut leading edges of the media units and (ii) an outlet defined at an end of the gate wall; a pick roller at the outlet for engaging an outer one of the media units in the stack and dispensing the outer media unit from the hopper to a media processing path; the gate wall including a flexible gate at the outlet, the flexible gate configured to deflect toward the media processing path responsive to the outer media unit being driven into the flexible gate by the pick roller, wherein the outer media unit deflects when passing by the flexible gate, permitting the outer media unit to be dispensed from the hopper.

A document receiving apparatus comprises a receiving port configured to receive a document into an apparatus main body, a document stopper configured to be pivotable between a first posture in which reception of the document is suppressed and a second posture in which the reception is permitted, a holding portion configured to hold the document stopper in the first posture, and a biasing portion configured to bias the document stopper held in the first posture to be set in the second posture

A paper feeding device 100 includes a support hook 5 that supports a lower edge of a front side of a bundle of stacked paper sheets X, and a paper trailing edge storing part 32 provided between a lower end of the abutting surface 31 and the paper feeding table 11, and the paper feeding device retracts the lowermost layer paper sheet of the loaded paper sheets so as to store its trailing edge in the paper trailing edge storing part 32 and then advance it.
