Claims

[Claims for Utility Model Registration] 1 A document placed on a document table is separated into one sheet by a separation roller, and the paper is fed by pull-out rollers disposed on both sides coaxially with the separation roller. In the automatic document feeder, the separating roller and the pull-out rollers on both sides thereof are supported by a common shaft whose both ends are rotatably supported by a pair of side plates, and at least one of the ends thereof is supported by a common shaft. An automatic document feeder characterized in that it is attached to a side plate via an auxiliary side plate that can be moved and fixed along the paper feeding direction. 2. In an automatic document feeder that separates a document placed on a document table into one sheet by a separation roller and feeds the document by pull-out rollers disposed on both sides coaxially with the separation roller, The separation roller and the pull-out rollers on both sides of the separation roller are supported by a common shaft whose ends are rotatably supported by a pair of side plates, and both ends of the shaft are rotated in the paper feeding direction according to the amount of deflection during use. The automatic document is characterized in that the positions of the outer circumferential surfaces of the pull-out rollers disposed on both sides of the separation roller are substantially coincident with each other by being attached to the pair of side plates with their positions shifted in the direction along the paper feed direction.
