摘要： An X-Y plotter is of the type which moves a non-perforated recording paper by drive rollers and pinch rollers. The outer surface of each of the drive rollers is formed with a cylindrical reference surface and with a plurality of minute projections of sharp quadrangular pyramidal shape distributed over the whole outer surface of the roller. These reference surface and minute projections are formed by machining in the entire circumferential or outer surface of the drive roller a plurality of trapezoidal grooves extending parallel and orthogonally to the axis of the drive roller.
