Abstract
A paper feed mechanism is provided. The paper feed mechanism includes a pair of paper feed rollers at the upstream side and the downstream side of a printing device in a direction in which a recording paper is fed during printing, and press contact rollers in press contact therewith. The back surface of the recording paper receives a pushing force from projections formed on the pair of paper feed rollers by a predetermined depth such that the recording paper is fed during printing by the printing device.
