ABSTRACT:
A sheet feeding device comprising a plurality of pickup rollers for exerting a feeding force P (gf) on thin sheets which have ream weights K (kg) less than 55 kg and one or more friction rollers for offering resistance to the thin sheets fed by the pickup rollers. A distance L (mm), in a feeding direction, between the pickup rollers and the friction rollers is set in a range defined by the relationship ##EQU1## so as to enable a feeding of the thin sheets with no buckling.
