Abstract

L'invention concerne un dispositif de lecture optique d'informations. Des diodes lumineuses divisées en plusieurs groupes éclairent la surface de lecture et l'information est lue par un système optique associé à un détecteur délivrant des signaux transmis, d'une part, à un circuit d'identification de contour et, d'autre part, à un circuit de commande qui fait varier la luminosité de chaque groupe de diodes afin de produire un éclairement uniforme des caractères devant être lus. Application aux dispositifs manuels et fixes de lecture de caractères, signes et symboles.
