Abstract

A document sheet feeder in accordance with the present invention includes a document sheet stacker, an inclined surface portion which is inclined by a predetermined angle with respect to the document sheet stacker, a separation roller which is disposed above the document sheet stacker and which has a plurality of equiangularly-spaced-apart blades extending radially outwardly from the outer surface of the separation roller, a feed roller disposed downstream of the separation roller in order to feed a separated sheet to a predetermined position and pinch roller movable to contact with or disengage from the feed roller. The separation roller is rotatably carried at the end of a first swinging arm and is moved between an operative position at which the sheet separation is effected and an inoperative position spaced apart from the operative position. A pinch roller is rotatably carried at the leading end of a second swinging arm which in turn is swung to a position at which the pinch roller is made into contact with the feed roller when the separation roller is in the operative position for separating a sheet one at each time.
