Abstract
A sheet feed mechanism utilizing a continuous form sheet, with a plurality of equally spaced sprocket holes formed on both side edges thereof in the direction along a straight sheet feed path, is fed between a photoconductive member and transfer member. Each side of the sheet feed mechanism includes an endless tractor belt looped between two feed rollers disposed upstream and downstream of the transfer member, respectively. In one aspect, engaging pins are provided on the circumferential surface of the feed rollers and engaging holes on the tractor belt spaced at the same interval as the holes of the continuous form sheet, to feed the sheet by engagement of the engaging pins and the sprocket holes through the engaging holes. In another aspect, the endless belt is provided with the engaging pins and a regulation member for moving the tractor belt such that a portion of its upper part is separated from the photoconductive member.
