A sheet feeding apparatus includes a detection unit provided to be movable with respect to a sheet stacking portion and configured to detect a sheet by causing a contact portion to come into contact with an uppermost sheet stacked on a stacking surface, wherein a bottom portion of the sheet stacking portion forms a part of a bottom portion of the sheet feeding apparatus, the sheet stacking portion is provided with a through hole configured to be expose in the case where no sheet is stacked on the stacking surface, the through hole penetrating the stacking surface to a bottom surface of the sheet stacking portion, and the contact portion is positioned inside the through hole in the case where no sheet is stacked on the stacking surface.

A sheet feeding device includes a roller pair being mutually non-separable; and a roller pair being mutually separable. The sheet feeding device temporarily stops a sheet in a registration position of the non-separable roller pair and then resumes feeding the sheet. The sheet feeding device feeds sheets such that a following sheet reaches the registration position from the separable roller pair after completion of ejection of a preceding sheet.

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 feeding apparatus includes a stacking portion, a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion, and a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction. The trailing-end regulating member includes a support portion configured to support a lower surface of the sheets stacked on the stacking portion. The support portion has a projecting shape in which a center portion of the support portion in a sheet width direction projects upward as compared with end portions of the support portion in the sheet width direction.

A bill storage unit of an automated teller machine according to an embodiment includes: a lower cassette and an upper cassette which have bills stored therein and are vertically stacked; an external control board disposed outside the lower cassette and the upper cassette to perform power supply and communication signal transmission to the lower cassette and the upper cassette; first and second internal control boards electrically connected to the external control board and disposed inside the lower cassette and the upper cassette to perform power supply and communication signal transmission to each of components inside the lower cassette and components inside the upper cassette; a plurality of connectors interconnected to electrically connect the external control board and the first and second internal control boards; and a position alignment means configured to, when the upper cassette is being stacked on the lower cassette, guide the plurality of connectors to be interconnected at correct positions.

A loading device includes a placement portion and a friction member. A single paper sheet discharged from a discharge unit is placed on the placement portion. The friction member is disposed downstream of a downstream end portion of the placement portion in a discharge direction, and includes a contact surface that can come into contact with a back surface, of the single paper sheet, facing the placement portion. The contact surface extends at least in the discharge direction, at a position lower than the height position of the downstream end portion in a height direction.

A sheet feeder includes a sheet stacker, a sheet feed roller, a separation roller pair, and a lifter. Sheets are conveyed and stacked on the sheet stacker. The sheet feed roller feeds the sheets. The separation roller pair separates the sheets fed by the sheet feed roller one by one. The lifter lifts and lowers the sheet stacker depending on a stack amount of the sheets. The sheet stacker includes a first stacking face, a second stacking face, and a bent portion integrally connecting the stacking faces such that the stacking faces form a specified angle. The sheet stacker stacks the sheets such that a center of gravity of the sheets is positioned above the first stacking face and integrally displaces the stacking faces when the lifter operates.

An article supporter for a supply device includes a feeder that supplies, by air suction, an uppermost thinly tabular article from a bundle of a plurality of thinly tabular articles that is stacked and is partially different in thickness, the article supporter for supporting the bundle with a gap between the uppermost thinly tabular article and the feeder, and the article supporter includes: a first support that supports respective thinner parts of the plurality of thinly tabular articles; a second support that supports respective thicker parts of the plurality of thinly tabular articles and is movable upward and downward; and an adjuster that adjusts a level of the second support such that the uppermost thinly tabular article of the bundle is set within a predetermined range in a vertical direction.

A paper sheet processing device includes: an ejection roller for ejecting a paper sheet; and a bill press for pressing the paper sheet against the ejection roller, wherein the bill press has: a bill press main body that moves in a direction to approach and separate from the ejection roller; a pressing portion that is provided on the ejection roller side of the bill press main body and moves in a direction to approach and separate from the bill press main body; and an elastic portion provided between the pressing portion and the bill press main body.

A sheet container includes a housing, a stacking part provided in the housing so that recording sheets are stacked on the stacking part, a contact part to be brought into contact with edges of the recording sheets in a length direction on the stacking part in an attached state in which the contact part is attached into the housing, a connection member connected to the stacking part or the housing and having an extension part longer than the stacking part in the length direction, and a retreater that retreats the contact part in the attached state from the extension part with the connection member connected to the stacking part or the housing.
