A cardboard packer is provided, comprising a blank magazine, a blank feeder, and a blank picker for transporting a single blank from the magazine to the feeder. The blank picker comprises an upper picking unit configured to attach to an upper portion of the blank, and a bottom picking unit configured to attach to a bottom portion of the blank.

A sheet feeding apparatus includes a sheet supporting unit, a sheet feed unit, an air separation unit configured to separate the uppermost sheet by blowing the air onto a side surface of the sheet bundle supported by the sheet supporting unit, a velocity detection unit configured to detect actual velocity of a sheet fed by the sheet feed unit, a drive load detection unit configured to detect an actual drive load for feeding the sheet by the sheet feed unit, and a controller configured to control the sheet feed unit and the air separation unit. In a case where the sheet is fed by the sheet feed unit, the controller is configured to control an operation of the air separation unit depending on the actual velocity of the sheet detected by the velocity detection unit and the actual drive load detected by the drive load detection unit.

An image forming apparatus includes a processor configured to: receive paper information on a type of paper on which an image is formed; acquire assist information about assistance to supply the paper by supplying gas to the paper and adjustment information about positioning of the paper after assistance to supply the paper is performed, the assist information and the adjustment information corresponding to the received paper information and relating to transport of the paper; and perform control for storing the paper information, the assist information, and the adjustment information in association with one another into a memory.

A feeder includes: a mount board that moves vertically while allowing sheet-shaped media to be stacked thereon; a transport device that allows an uppermost one of the sheet-shaped media stacked on the mount board to be sucked by a suction portion to transport the uppermost sheet-shaped medium to a transporter and to feed the uppermost sheet-shaped medium to a destination; left and right edge air blowers that blow air to left and right edge portions, when viewed from an upstream side in a transportation direction, of upper ones of the sheet-shaped media stacked; and left and right detectors that are disposed on left and right sides of the suction portion at the same position in the transportation direction, and that individually detect downward or upward bend amounts of left and right edge portions of the uppermost sheet-shaped medium.

A medium-suction apparatus includes a conveyer to convey a medium in a conveyance direction, a first suction unit to perform suction operation on the medium to attract the medium to the conveyer, and a second suction unit to perform the suction operation on the medium to attract the medium to the conveyer. The second suction unit being disposed next to the first suction unit in a width direction perpendicular to the conveyance direction. The second suction unit starts the suction operation after the first suction unit stalls the suction operation.

A sheet feeding apparatus includes: a placer that allows a plurality of sheets to be placed on the placer; an air feeder including a front-end fan that generates an airflow from a front-edge side in a sheet feeding direction of a bundle of sheets placed on the placer toward the bundle of sheets; an attracting conveyor that attracts an uppermost sheet separated by the air feeder from the bundle of sheets placed on the placer and conveys the uppermost sheet; a detector that detects, in the conveyance of the uppermost sheet by the attracting conveyor, an amount of co-feeding of a next sheet together with the uppermost sheet; and a hardware processor that executes air-volume control to the front-end fan such that an air volume of the front-end fan increases with an increase in the amount of co-feeding detected by the detector.
