A system capable of automatically producing drawings on a very small scale, comprises an electron optical system which forms a highly reduced elemental image from a diaphragm. A scanning system enables this image to be displaced line-by-line in a first direction over the recording surface and a mechanical system displacing the surface in a direction perpendicular to the first. The whole is controlled by a logic system which delivers code numbers indicating the programme to be executed for each line. |
