Copying and telecopying device using a mechanism ensuring the analysis of a document by a scanning beam which, transmitted from the document, is sent to a drum coated with selenium. According to the invention, the equipment is completed by a laser source whose beam can be directed along two parallel incident paths, to a helical mirror, one of the beams being used for the analysis of the document and the transmission of the information at a distance, the other beam being modulated by a facsimile signal and being directed onto the drum coated with selenium. |
