DOCUMENT SHEET FEEDER

摘要

A document sheet feeder in accordance with the present invention comprises a document sheet stacker (106), an inclined surface portion (108) which is inclined by a predetermined angle with respect to the document sheet stacker (106), a separation roller (130) which is disposed above the document sheet stacker (106) and which has a plurality of equiangularly-spaced-apart blades extending radially outwardly from the outer surface of the separation roller (130), a feed roller (112) disposed downstream of the separation roller (130) in order to feed a separated sheet to a predetermined position and pinch roller (116) movable to contact with or disengage from the feed roller (112). The separation roller (130) is rotatably carried at the end of a first swinging arm (132) and is moved between an operative position at which the sheet separation is effected and an inoperative position spaced apart from the operative position. The pinch roller (116) is rotatably carried at the leading end of a second swinging arm (120) which in turn is swung to a position at which the pinch roller (116) is made into contact with the feed roller (112) when the separation roller (130) is in the operative position for separating a sheet one at each time.
