    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.
