Abstract

L'invention porte sur un dispositif de balayage de document en vue de son analyse ou de sa restitution. La tête de balayage comporte n cellules d'analyse ou d'impression alignées et réparties régulièrement les unes par rapport aux autres pour correspondre respectivement à n points elémentaires équidistants les uns des autres le long d'une ligne de balayage du document de N points élémentaires, et est animée relativement au document d'un mouvement linéaire alternatif d'amplitude définie pour que chacune des n cellules balaye sur une même ligne N/n points consécutifs. Application : transmission et reproduction de documents.
