A box making machinery and a corrugated board running register method, include a feeding unit, a processing apparatus which carries out processing on a corrugated board, a running register device which adjusts the processing position of the processing device in a carrying direction of the corrugated board, and a control device which controls the running register device, wherein the control device includes a carrying misalignment amount calculation unit which calculates the carrying misalignment amount of the corrugated board from the feeding unit to a preset predetermined carrying position, and a control unit which adjusts the processing position of the corrugated board to be processed next using the running register device on the basis of the carrying misalignment amount after processing of the corrugated board has finished.

An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

A sheet handling apparatus includes a transport path that includes a first path, a second path, and a curved portion connecting the first path and the second path, the transport path circularly transports a sheet along the transport path in a forward direction or a backward direction. The sheet handling apparatus further includes a rolling body that is disposed at the curved portion and rotates clockwise and counterclockwise, and a plurality of rollers that are opposed to the rolling body and sandwich the sheet between each of the plurality of rollers and the rolling body along the curved portion of the transport path. The rolling body transports the sheet in the forward direction by rotating clockwise and transports the sheet in the backward direction by rotating counterclockwise.

A medium conveying apparatus includes a medium tray, a feed roller, an upper guide, a movement sensor including an arm movably provided by the fed medium on the upper guide and on an upstream side of the feed roller, to generate a movement amount signal corresponding to a movement amount of the arm, a medium sensor to detect a presence of the medium at a predetermined position of the medium tray, a processor to determine whether a feeding abnormality of the medium has occurred based on the movement amount signal, detect a size of the medium placed on the medium tray based on a detection result by the medium sensor, and stop feeding of the medium by the feed roller when the processor determines that the feeding abnormality of the media has occurred and the detected size of the media is equal to or less than a predetermined size.

A flexural document pick-up device includes: a feeding path comprised of a upper wall and a lower wall; a input tray arranged upstream to the feeding path; a paper feeding unit arranged partially in the feeding path; a separation roller disposed on the opposite side of the paper feeding unit; a blocking arm disposed upstream to the paper feeding unit; a securing groove arranged on the upper wall; and a guiding unit with the following portions disposed sequentially from downstream to upstream of the feeding direction: a securing section which is secured to the securing groove, a flexure section which is extended from the securing section to the feeding path, a guiding section which is connected to the flexure section and essentially parallel to the feeding path, a lifting section which is connected to the guiding section and a vertex which is arranged on the end of the lifting section.

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.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

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 tray unit assembly includes a housing, a separating/stacking unit, a tray unit and an elevating member. The separating/stacking unit includes a separating roller unit and a stacking roller unit provided in the housing. The tray unit is provided to be inserted into the housing and includes a first tray body fixed to the housing when the tray unit is inserted into the housing, and a second tray body connected to the first tray body to be slidable in a vertical direction and having a media stacking space formed therein. The elevating member is disposed to be movable up and down and configured to be in contact with a bottom surface of the second tray body to move the second tray body toward the stacking roller unit or the separating roller unit.

A transporting apparatus (for example, image reading apparatus) includes a transporting mechanism that transports a document along a transporting path and a processing unit that determines an inclination error of the document. The processing unit determines whether or not the inclination error has occurred in accordance with a document size and a tilt angle of the document.
