摘要： In a sheet conveyance apparatus a control unit controls lifting and lowering of a sheet supporting portion by a lifting unit and executes a mixed feeding in one of a plurality of modes including a first mode and a second mode. The mixed feeding is an operation in which a plurality of sheets having different lengths in a width direction orthogonal to a feed direction of a sheet feeding unit are fed by the feeding unit, wherein in the first mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on an instruction to start sheet feeding, and in the second mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on a detection of a sheet by the detection unit.

摘要： A device for changing a sheet pile (14) in a sheet feeder (10) for a sheet treating machine comprises a main pile supporting unit (18) with a main pile actuating unit (20) for lifting and lowering the main pile supporting unit (18), wherein the main pile supporting unit (18) comprises a supporting surface (22) adapted to support a pallet (16) carrying a sheet pile (14). The device further comprises a residual pile supporting unit (24) with a residual pile actuating unit (26) for lifting and lowering the residual pile supporting unit (24). The residual pile supporting unit (24) comprises a plurality of residual pile bars (38) extending substantially parallel to each other and being substantially parallel to the supporting surface (22) of the main pile supporting unit (18), wherein the residual pile bars (38) are coupled to a bar actuating unit (43) adapted to move the residual pile bars (38) on a line parallel to the direction of extension of the respective residual pile bar (38) into a sheet pile region (30) and retract the residual pile bars (38) from the sheet pile region (30). The bar actuating unit (43) is configured to retract the residual pile bars (38) while introducing an oscillatory movement of the residual pile bars (38) along the direction of extension of the residual pile bars (38).
Further, a method for changing a sheet pile (14) in a sheet feeder (10) is presented.-

摘要： Examples relating to determining stack height in imaging devices are described herein. According to one example, an imaging device includes an input roller assembly to transport a print medium towards an image-forming assembly of the imaging device. The input roller assembly can include a pinch roller for drawing the print medium from a media stack. The imaging device further includes a pressure plate movably coupled to a body portion of the imaging device and biased towards the pinch roller. The pressure plate may hold the media stack between itself and the pinch roller and is movable by a first distance from a neutral position when the media stack is there between. The first distance is measured from a fixed point to a measurement region on the pressure plate and can indicate an instantaneous stack height of the media stack.

摘要： A sheet feeding cassette includes a main body, a lift plate, a pair of side cursors, and an auxiliary lift plate. The main body is configured to accommodate a sheet fed out in a predetermined sheet feeding direction. The lift plate is provided in the main body in a liftable manner, and has a sheet placement surface on which the sheet is placed. The pair of side cursors is configured to be moved in a width direction perpendicular to the sheet feeding direction and to come into contact with side edges of the sheet placed on the lift plate to align the sheet. The auxiliary lift plate is detachably attached to a notch portion which is formed in the lift plate so as to allow a moving of the side cursors.

摘要： Sheets are set on the top face of a lift plate. A lift mechanism makes a lift plate ascend and descend. A sheet feeding roller and a distance sensor are provided over the lift plate. The distance sensor measures a distance (measured distance) to a measurement target placed below. Based on the measured distance before the lift plate is raised, the controller calculates a remaining quantity value indicating a remaining quantity of sheets. When, after the lift plate starts to rise, the recognized measured distance becomes equal to or smaller than the upper limit distance, the controller makes the lift mechanism stop raising the lift plate.

摘要： There is provided a mechanism for determining whether to perform processing of lifting up a document tray upon detection of a document depending on an active application. A method for controlling an image processing apparatus includes lifting up a document tray upon placement of a document on the document tray, conveying the document placed on the document tray lifted up in the lifting, reading the document conveyed in the conveying, and registering, for an application, whether to lift up the document tray upon the placement of the document on the document tray.

摘要： An apparatus and a method for singling value documents involve a feeding device adapted to feed a respectively uppermost value document of a stack of value documents to a picking device adapted to pick the value document from the stack. A conveying device is adapted to receive the stack and to convey it relative to the feeding device. A distance sensor is adapted to detect at least one distance of the respectively uppermost value document of the stack received by the conveying device relative to the feeding device and generate at least one corresponding distance sensor signal. A control device is adapted to control the conveying of the stack relative to the feeding device and the location of the feeding device relative to the stack based on the distance sensor signal.
