Abstract

Lecture de caractères codés. Les caractères codés en CMC-7 sur un support 6 engendrent, en passant devant une tête magnétique 10, des impulsions traduisant les fronts des segments du caractère. Une horloge 33, attaquant un compteur 8 recevant les impulsions détectées, permet de mesurer les distances entre les impulsions consécutives. Les résultats de ces mesures sont transmis à une mémoire 20. Grâce à un microprocesseur et à un répertoire des cas d'erreurs possibles, les données contenues dans 20 sont décodées par comparaisons séquentielles. Traitement de données.Reading of coded characters. The characters encoded in CMC-7 on a support 6 generate, passing in front of a magnetic head 10, pulses reflecting the edges of the segments of the character. A clock 33, driving a counter 8 receiving the detected pulses, makes it possible to measure the distances between the consecutive pulses. The results of these measurements are transmitted to a memory 20. Thanks to a microprocessor and to a directory of possible error cases, the data contained in 20 are decoded by sequential comparisons. Data processing.
