An example print medium supplying apparatus includes a print medium transporting device to pick up a print medium loaded in a loading portion and transport the picked-up print medium, a print medium alignment portion to align a leading end of the transported print medium, a first sensor to sense the print medium that passes through a feed roller of the print medium transporting device, and a processor to, based on a measured value with respect to the print medium sensed by the first sensor and a multi-feeding determination reference value corresponding to a sheet of the print medium, detect multi-feeding of the print medium and process the detected multi-feeding by controlling the print medium transporting device and the print medium alignment portion.

A pick-up device disposed between an input tray and a feeding path includes a paper feeding unit for feeding paper, a separation roller disposed opposite to the paper feeding unit, a blocking arm disposed between the input tray and the paper feeding unit and configured to be switchably disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path, and a guiding arm disposed in the feeding path through a pivot shaft and having a guiding portion. The pivot shaft is located upstream of the separation roller, and the guiding portion is swingably disposed in a seam space formed by the paper feeding unit and the separation roller.

A placement method using a placement device provided with a first process of pressing a transfer plate a topmost layer sheet member so as to pick up it when a restraint device is rendered a restraining state, a second process of rendering the restraint device a non-restraining state to render the transfer plate an inclined state while pressing down the plurality of sheet members from above in the stacking direction by a base end part side of the transfer plate rendered the inclined state, a third process of inserting the restraining blade into the space formed between the topmost layer sheet member and the sheet member of the layer below it and again render the restraint device the restraining state, and a fourth process of making the transfer plate retract upward while returning it to the horizontal state and transferring the topmost layer sheet member to the holder.

A paper feed apparatus. The paper feed apparatus can include a stack of paper, the stack of paper having an uppermost sheet of paper and a second sheet of paper being disposed below the uppermost sheet of paper. A driven pick roller is suitably arranged in contact with the uppermost sheet of paper and is suitably rotatable in a first roller direction to convey the uppermost sheet of paper in a first paper direction. A nip defined by a driven feed roller and a separation roller is suitably disposed downstream from the pick roller, the nip having a gap sufficient for the uppermost sheet of paper to pass through, the gap being sufficient for the separation roller to be in frictional engagement with the second sheet of paper to prevent it from passing through the nip. A rotating element having a plurality of radially extending brush elements is suitably disposed between the driven pick roller and the driven feed roller and rotatable in a second direction opposite the first roller direction to urge the second sheet of paper under the influence of the plurality of radially extending brush elements in a second paper direction opposite the first paper direction.

The pick-up device disposed between the input tray and the feeding path and includes a Paper feeding unit for feeding the paper from the input tray; a separation roller disposed opposite to the Paper feeding unit and contacting each other; a blocking arm disposed between the input tray and the Paper feeding unit, and configured to be switchable disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path; and a guiding arm, the guiding arm is disposed in the feeding path through a pivot shaft, and includes a guiding portion, the pivot shaft is located upstream of the separation roller, and the guiding portion is swingable disposed in a seam space formed by the Paper feeding unit and the separation roller; and wherein a distance from the axle of the separation roller to the guiding portion is greater than the wheel diameter of the separation roller, and the vertical distance between the paper to be fed and the guiding portion is greater than the vertical distance between the paper to be fed and the separation roller.

A paperboard sheet and a method of using the paperboard sheet is provided in which a surface of the paperboard sheet provides a pattern of indentations, the indentations reducing the surface area between adjacent sheets to facilitate the transfer of a top sheet from a stack of similar sheets.
