ABSTRACT:
A paper feed device that uses a separating pawl for preventing overlapped feeding of sheets of recording paper wherein the separating pawl does not resist the feed of paper, thereby ensuring smooth paper feed. In the paper feed device, a sheet of paper is fed from a hopper and moved along a separating tilt plane to be separated from the stacked paper by the separating pawl which is pressed toward the paper path by a spring. Each separate sheet of paper is fed between a paper guide plane and an arm section to a print head by a feed roller and a follower roller. When a paper supply roller is in a stopped state, the sheet of recording paper is pulled by the feed roller to be straightened between a collar member and the paper guide plane such that the sheet of paper is away from the separating pawl and therefore is not affected by the resistance of the separating pawl, ensuring a smooth feed.
