The requirement of transfer on wires of images — drawings, drawings and texts, led to the invention the telegraph of Kazelli in 1855. The transferred image needed to be drawn on a leaf of a tin foil with special ink which isn’t carrying out an electric current and to strengthen on a metal plate of the transferring device. • Operation of devices of Kazelli on the line Petersburg-Moscow in 1866 -1868 revealed their unfitness because of complexity of service, low capacity and high cost of operation

Digitizer consists from • — tablet to which the image fastens; and • — feather by means of which the position on a tablet is specified. • When moving feather on a tablet in memory of the computer feather coordinates in consecutive points are fixed. • Not the last role is played the tablet application in creation on the computer drawings and sketches. The artist draws on the screen, but his hand drives a feather on a tablet. At last, a digitizer is possible to use simply as an analog of a mouse. The special case is digitizer sensitive to pressing.
