Abstract

Un ordinateur central et un clavier sont connectés à une unité de traitement d'images reconnaissant les caractères dans les données d'images lues par un lecteur d'images de sorte que les caractères puissent être entrés sélectivement de deux manières. La première consiste à entrer les caractères reconnus en fonction des données d'image lues par le lecteur d'images, et la deuxième à entrer simplement ces derniers par le clavier connecté à l'ordinateur central. Lorsque les caractères sont entrés par le clavier, le clavier est connecté à l'ordinateur central par l'unité de traitement des images. A l'inverse, lorsque le lecteur d'images est utilisé, les signaux représentant les résultats de la reconnaissance des caractères sont transmis à l'ordinateur central de sorte que ces derniers puissent être distingués des signaux provenant du clavier. Le lecteur d'image présente un élément de préhension permettant un fonctionnement manuel, facilitant le balayage d'un original.
