A paper sheet transport apparatus (10) includes transport member that is slidable along the widthwise direction of a transport path (11) (e.g., a drive roller (36) and a driven roller (38)), and a paper sheet detection unit (inlet-side paper sheet detection sensor (70)) that is arranged on an upstream side of the transport member in the paper sheet transport direction along the transport path (11) and detects the position of the paper sheet in the widthwise direction of the transport path (11). A control unit (80) calculates an amount of movement of the transport member based on the position of the paper sheet in the widthwise direction of the transport path (11) detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path (11).

A sheet processing apparatus includes a first holding unit configured to hold one or more sheets and movable in a sheet transport direction, a first drive unit configured to move the first holding unit in a first direction along the sheet transport direction, a biasing member that biases the first holding unit in a second direction opposite to the first direction, and an energy storage unit that stores energy discharged from the biasing member.

The apparatus is capable of handling sheets of various lengths while suppressing an increase in apparatus size, wherein each of a pair of regulating guides is movable to a guide position at which an end edge of a sheet in a sheet width direction can be guided by a guide surface and to a retracting position retracting further away from the sheet width direction end edge than the guide position. For sheets S1 and S2 each having a first sheet length, the pair of regulating guides is made to reach the guide position from the retracting position in a state where the front end of the sheet is located between upstream and downstream ends of the guide surface. For a sheet S3 having a second sheet length that is longer than the first length, the pair of regulating guides is made to reach the guide position from the retracting position.

A sheet feeding apparatus includes a supporting portion, a sheet feeding unit, a side edge regulation plate, a separation unit configured to separate the sheets by blowing air onto the plurality of sheets supported by the supporting portion, a regulation plate position detection unit configured to detect a position of the side edge regulation plates in the width direction, and a control unit configured to execute a separation mode so as to perform an air-blow operation by the separation unit in feeding the sheets by the sheet feeding unit. In the separation mode, in a case where the position of the side edge regulation plate detected by the regulation plate position detection unit does not correspond to size of the sheets supported by the supporting portion in the width direction, the control unit is configured to stop the air-blow operation.

An apparatus for aligning at least one note of value along a transport path includes at least one transport element driven by at least one first drive unit and at least one counter-pressure element arranged opposite to the transport element. The transport path of the note of value extends between the transport element and the counter-pressure element. The counter-pressure element is ball-shaped and is mounted so as to be freely rotatable. Further, the apparatus includes a second drive unit for displacing the transport element along its axis of rotation so that a note of value arranged between the transport element and the counter-pressure element is moved transversely to the transport direction during displacement of the transport element.

A page registration system may include, in an example, a media edge sensor to detect a location of an edge of a print media along a media feed path and in a direction non-parallel to the media feed path and a calibration sensor downstream of the media edge sensor to detect changes in the location of the edge of the print media in the direction non-parallel to the media feed path, and provide calibration data to the page registration system to correct changes in the location of the edge of the print media in the direction non-parallel to the media feed path.

A sheet processing apparatus includes a conveying roller that conveys a sheet, a processing tray on which the sheet from the conveying roller is loaded, a reference stopper provided at one end of the processing tray, a return paddle having an elastic piece for transferring the sheet from the conveying roller to the reference member, and a roller arm that moves the return paddle in the sheet thickness direction at a predetermined moving rate according to the number of sheets loaded on the processing tray. The moving rate of the roller arm is reduced as the number of sheets loaded on the processing tray is increased. With this configuration, aligning property of even a wavy sheet can be suppressed from being deteriorated at sheet loading.

A folding arrangement including a flap lifting assembly located at a drop conveyor discharge end and including a pivoting arm with a flap engaging surface that is movable between a first, flap-lifting position and a second, pass-through position is provided. A folding assembly includes a receiving conveyor with a receiving conveyor feed end positioned below the drop conveyor discharge end, and a folding finger above the receiving conveyor feed end. The product-substrate combination is driven by the drop conveyor into contact with the flap engaging surface in the first position to lift the flap as the product-substrate combination is discharged from the drop conveyor discharge end towards the receiving conveyor feed end, and the folding finger contacts the flap of the product-substrate combination to complete folding of the flap to a second angled position onto the product as the product-substrate combination pivots the flap engaging surface to the second position.

A sheet processing system according to an embodiment includes a tray that supports a sheet on opposite sides of the sheet orthogonal to a conveyance direction of the sheet. The tray includes a first adjustable support and second adjustable support positioned opposite the first adjustable support in the direction orthogonal to the conveyance direction of the sheet. A skew sensor detects a skew angle of the sheet conveyed to the tray. A corner sensor detects positions of each corner on a front end in the downstream direction of the sheet conveyed to the tray. A controller controls movement of the first and second adjustable supports based on the detected skew angle and the detected positions of each corner on the front end of the sheet conveyed to the tray so that the sheet is conveyed to the tray without jamming.

In accordance with an embodiment, a sheet processing apparatus comprises a processing tray, a longitudinal alignment mechanism, a horizontal alignment mechanism and an interlocking mechanism. The processing tray can stack a sheet. The longitudinal alignment mechanism includes a rotatable paddle. The longitudinal alignment mechanism can align the sheets stacked on the processing tray in a sheet conveyance direction. The horizontal alignment mechanism includes a horizontal alignment plate movable in a sheet width direction orthogonal to the sheet conveyance direction. The horizontal alignment mechanism can align the sheets placed on the processing tray in the sheet width direction. The interlocking mechanism interlocks the paddle in the sheet width direction in synchronization with the movement of the horizontal alignment plate in the sheet width direction.
