ABSTRACT:
A sheet feeding device including a sheet separating mechanism consisting of a feeding member and a braking separating member for preventing feeding of a plurality of sheets, and a speed adjusting mechanism for varying as desired the sheet feeding speed. The spacing between the feeding member and the braking separating member is determined based on a predetermined sheet feeding speed, and the sheet conveying force exerted by the feeding member is set at a level higher than the sheet arresting force exerted by the braking separating member. A supporting member for journalling at least one of the feeding member and the braking separating member and being movable for movement of one member toward the other member, and a transmission for moving the supporting member in synchronism with the movement of an adjusting member of the speed adjusting mechanism are provided, to vary the spacing between the feeding member and the braking separating member in accordance with a change in the sheet feeding speed.
