Abstract

Dispositivo per la lettura di documenti comprendenti informazioni principali e informazioni ausiliarie di diverso colore ottico. I documenti presentano un indicatore di posizione e un contrassegno indicatore del colore delle informazioni ausiliarie. Comprende mezzi optoelettronici per percepire l'indicatore di posizione e il contrassegno, atti a pilotare sorgenti luminose o filtri di colore coerenti cromaticamente, con dette informazioni ausiliarie o contrassegni per cui un rilevatore di informazione può leggere le informazioni principali rimanendo "cieco" nei riguardi di quelle ausiliarie che hanno diverso colore ottico.(FIG. 7)Device for reading documents comprising main information and auxiliary information of different optical color. Documents have a location marker and a color marker for auxiliary information. It includes optoelectronic means for perceiving the position indicator and the mark, suitable for driving chromaticly coherent light sources or color filters, with said auxiliary information or marks for which an information detector can read the main information while remaining "blind" towards the auxiliary ones that have different optical color. (FIG. 7)
