摘要： A sheet feeding device includes a sheet stacker configured to stack a sheet bundle; a blower configured to float a sheet on an upper portion of the sheet bundle; a conveyor configured to convey the sheet floated by the blower; a lift configured to lift up and down the sheet stacker; a first reflective optical sensor configured to detect the sheet floated by the blower; a second reflective optical sensor configured to detect the sheet bundle and a side face of the sheet stacker, the side face including a detection region to be detected by the second reflective optical sensor and a non-detection region not to be detected by the second reflective optical sensor; and circuitry configured to control the lift based on a detection result of the first reflective optical sensor and a detection result of the second reflective optical sensor. The circuitry is configured to cause the lift to lift up the sheet stacker in response to a change from a detection state to a non-detection state of the second reflective optical sensor.

摘要： A sheet feeding device includes a sheet stacking table, an air blower, a feeder, and an air sucker. The sheet stacking table stacks a bundle of sheets. The air blower blows air to the bundle of sheets to float an uppermost sheet from the bundle of sheets. The feeder feeds the uppermost sheet. The air sucker sucks air in such a direction that a sheet in vicinity of the uppermost sheet moves away from the feeder. The air sucker includes a suction nozzle to suck air, a suction fan to generate a negative pressure, a suction duct to communicate the suction nozzle with the suction fan, and an opening-and-closing mechanism to shut off and release ventilation in the suction duct.

摘要： In the present invention, when a status of clogging a paper due to some cause occurs, controls of inverting a conveyance roller and returning the jammed paper in a paper feeding tray is performed. At this time, the position of a paper damming up member is lowered by an actuator when the jammed paper is returned to the paper feeding tray and the conveyance roller is inverted so as to avoid a state in which the paper damming up member 33 hinders the returning of the paper and the paper cannot be returned to the paper feeding tray. The paper damming up member is lowered to a position that is lower than a conveyance guide plate at a downstream side in a paper conveying direction. Then, the paper is returned to the paper feeding tray without damage. The returned paper can be reused.
