ABSTRACT:
An X-Y plotter disclosed is of the type which moves a recording paper with no perforation by drive rollers and pinch rollers. A plurality of sharp projections are arranged on the outer surface of each of the drive rollers such as to enable an exact feeding of the paper without any slippage. These projections are formed by cutting in the outer surface of each drive roller with V-grooves parallel and orthogonal to the shaft of the drive rollers.
