Abstract
A sheet feeder includes an attraction separation unit including an attraction belt facing the upper surface of a stacked sheet bundle to attract an uppermost sheet thereof, and rotatably supported by a support member at a position upstream of the attraction belt in a sheet feeding direction; and a swing device for swinging the attraction separation unit around the support member as a fulcrum to move the attraction belt between an attraction position and a feed position more distant from the sheet bundle than the attraction position is. The swing device includes a first drive transmitting portion attached to a downstream end portion of the attraction separation unit and a second drive transmitting portion attached to the body of the sheet feeder and connected with the first drive transmitting portion. The first drive transmitting portion and the rack connect to swing the attraction separation unit.
