Frequency generator for magnetic card reader-encoder device

Generator of several frequencies from a single frequency 4 for a magnetic card reader-encoder 1 comprising: - a sensor for the speed 2-3 generating this frequency 4; - a write logic 13 or 14 associated with a write head 23-24. It comprises: - a frequency 4 multiplier unit 5; - two dividers 7-8 connected to the output 12 of 5, intended to send out a signal of predetermined frequency signal 6 which is not a multiple of one another, available for the write logic 13 or 14; - a third divider 9 connected to 12 and to the comparison input 10 of 5, intended to adjust the multiplication ratio of 5. GENERATEUR DE PLUSIEURS FREQUENCES POUR LECTEUR-ENCODEUR DE CARTES MAGNETIQUES 1 A PARTIR D'UNE SEULE FREQUENCE 4 COMPORTANT:-UN CAPTEUR DE LA VITESSE 2-3 GENERANT CETTE FREQUENCE 4;-UNE LOGIQUE D'ECRITURE 13 OU 14 ASSOCIEE A UNE TETE D'ECRITURE 23-24.IL COMPORTE:-UN ORGANE MULTIPLIEUR 5 DE LA FREQUENCE 4;-DEUX DIVISEURS 7-8 CONNECTES A LA SORTIE 12 DE 5, DESTINES A EMETTRE UN SIGNAL DE FREQUENCE 6 PREDETERMINE NON MULTIPLE L'UN DE L'AUTRE, DISPONIBLE POUR LA LOGIQUE D'ECRITURE 13 OU 14;-UN TROISIEME DIVISEUR 9 CONNECTE A 12 ET A L'ENTREE DE COMPARAISON 10 DE 5, DESTINE A AJUSTER LE RAPPORT DE MULTPLICATION DE 5.
