Abstract
An automated drawing system has an automatic drawing machine which receives input data from a central control unit for making a drawing on a roll of drawing paper in accordance with the input data. At the time of making the drawing, the automatic drawing machine also encodes the drawing paper with a bar code pattern representative of the lengthwise and widthwise size of the drawing. The drawing paper is then advanced to a paper cutter system which includes a bar code reader for reading and decoding the bar code pattern and for producing therefrom control signals indicative of the desired lengthwise and widthwise size of the drawing. These control signals are fed to a Y-axis or widthwise cutter and an X-axis or lengthwise cutter which accordingly cut the drawing paper in lengthwise and widthwise directions to obtain a cut piece of drawing paper containing thereon the drawing and having a size determined by the bar code pattern.
