Abstract (en)
A paper feeder for a printer comprises a feed roller (3) for conveying paper and a stepping motor (2) for driving the feed roller (3). The feed roller and the stepping motor are coaxially disposed and the feed roller is directly driven by the stepping motor. The stepping motor (3) is adapted to perform Z base steps per one revolution and, in a microstep exciting system, each base step is subdivided into n microsteps in accordance with the expression n.Z = pi Y.X in which X represents the resolution of the printer, Y represents the diameter of the feed roller (3), and n represents an integer of 2 or greater. <IMAGE>
