Abstract
LE DISPOSITIF DE FRAPPE DE CETTE IMPRIMANTE EST MUNI D'UN ORGANE DE FRAPPE QUI EST ENTRAINE PAR VOIE ELECTROMECANIQUE ET DONT LA POSITION ET LA VITESSE SONT MESUREES OU CALCULEES A L'AIDE D'UN TRANSDUCTEUR ET DE MOYENS DE CALCUL EN VUE DE DISPOSER D'UN SIGNAL DE VITESSE ET D'UN SIGNAL DE POSITION. LE SIGNAL DE VITESSE EST COMPARE A UN SIGNAL DE REFERENCE DANS UN COMPARATEUR. LA SORTIE DE CE COMPARATEUR EST RACCORDEE A UNE ENTREE D'UN DISPOSITIF D'EXCITATION ELECTRIQUE DEVANT COMMANDER L'ORGANE DE FRAPPE, L'EXCITATION NE PRENANT FIN QUE SI LA SORTIE DE SIGNAL DU COMPARATEUR EST DEVENUE LE SIEGE D'UN SIGNAL D'ARRET. LES SIGNAUX DE VITESSE ET DE POSITION DETERMINENT L'INTENSITE DU COURANT D'EXCITATION POUR OBTENIR UNE VITESSE CONSTANTE DE L'ORGANE DE FRAPPE ET POUR OBTENIR UNE DUREE DE VOLEE CONSTANTE DE CET ORGANE. APPLICATION AUX IMPRIMANTES RAPIDES.
