Abstract:
A sheet feeding device includes: a lift-blowing unit which blows air to a plurality of sheets stacked on a tray to lift an uppermost sheet from the sheets; a sheet absorbing unit which absorbs the sheet lifted by the lift-blowing unit by a negative pressure; an air suctioning unit which supplies the negative pressure to the sheet absorbing unit by air suction; a handling-blowing unit which handles the sheets by blowing air to the sheets absorbed onto the sheet absorbing unit; and a sheet transporting unit which transports the absorbed sheet, wherein the handling-blowing unit adjusts a volume of air blown thereby.
