A device for scanning a drawing and/or for printing a drawing paper with a pattern corresponding to said drawing, which comprises a support for holding the drawing and/or the drawing paper; a scanning head for generating electrical signals corresponding to said drawing, and/or a printing head which is fed the corresponding electrical signals for printing the pattern; means for generating relative motion between said support and the scanning head and/or the printer head in one direction; means for generating relative motion between support and scanning head and/or printer head in another direction, normal to the first; one electronic trigger generator for the generation of scanning and/or printer trigger signals when a point of the drawing should be scanned or when a point of the pattern should be printed; one release circuit for the successive release of a given number of scanning and/or printer trigger signals; and another release circuit for connecting the means for the relative motion in the second direction during such time intervals in which the scanning and/or printer trigger signals are not released. |
