A feeder includes a mount board that moves vertically while allowing sheet-shaped media to be stacked thereon; a transport device 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 medium to a transporter and to feed the uppermost medium to a destination; left and right edge air blowers blow air to transportation left and right edge portions of upper ones of the sheet-shaped media stacked; and a tip-end air blower blows air to below the uppermost medium sucked by the suction portion from a position downstream from a transportation leading end of the uppermost medium in a transport direction. When the uppermost medium is sucked by the suction portion, the feeder performs a first operation of spacing an upwardly bent transportation leading-end portion of a second uppermost medium apart downward from the sucked uppermost medium.

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 sheet feeding apparatus includes a tray that stores a recording medium in a closed state in which the tray is placed in an apparatus body, the tray being capable of being pulled out from the apparatus body in a predetermined pulling direction; a transport unit that is provided on the apparatus body and that transports the recording medium in a direction crossing the pulling direction when the tray is in the closed state; a first contact portion provided on the tray and having a contact surface spaced from the transport unit when viewed in the pulling direction, the first contact portion being located upstream of the transport unit in the pulling direction and the contact surface being in contact with an upstream end portion of the recording medium stored in the tray in the pulling direction when the tray is in the closed state; a second contact portion disposed at a position that is upstream of the transport unit in the pulling direction and at which the second contact portion overlaps the transport unit when viewed in the pulling direction, the second contact portion having a contact surface that is in contact with the end portion when the tray is in the closed state; a first overlapping portion provided on the first contact portion and disposed downstream of the second contact portion in the pulling direction, the first overlapping portion overlapping the second contact portion when viewed in the pulling direction; and an urging portion that urges the second contact portion downstream in the pulling direction so that the second contact portion abuts against the first overlapping portion when the tray is in the closed state.

A sheet conveying device includes a sheet stacker, an air blower, a guide, and a holder. The sheet stacker stacks sheets. The air blower blows air to the sheets on the sheet stacker. The guide is disposed facing an uppermost sheet of the sheets on the sheet stacker. The holder holds the guide and has a groove along which the guide is inserted. The groove has a plurality of direction switching portions at each of which the guide changes a direction of movement when the groove receives the guide.

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.

A sheet transport device includes a processor configured to change lifting control for lifting sheets on a tray, which are to be floated up and handed over, from normal state control to small-quantity state control in a case where it is detected that the remaining number of sheets on the tray is small.

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.
