Abstract

L'INVENTION EST RELATIVE A UNE MACHINE A ECRIRE COMPRENANT UN MOTEUR UNIQUE 16. CE MOTEUR 16 EST ASSERVI PAR UN CIRCUIT LOGIQUE 62 DETERMINANT LE SENS ET L'AMPLITUDE DE LA ROTATION DE L'ARBRE MOTEUR 17 POUR TOUS LES ORDRES DONNES SUR LE CLAVIER 2. LES DEUX EXTREMITES DE L'ARBRE MOTEUR 17 COOPERENT ALTERNATIVEMENT, PAR L'INTERMEDIAIRE D''UN PREMIER MECANISME DE SELECTION, AVEC L'ARBRE DE SELECTION 6 ET AVEC UNE POULIE DE TRANSMISSION 19. CETTE DERNIERE 19 EST SUSCEPTIBLE D'ENTRAINER, PAR L'INTERMEDIAIRE D'UN SECOND MECANISME DE SELECTION, SOIT LES DEPLACEMENTS DU CHARIOT 4, SOIT UNE ROTATION DU CYLINDRE DE FRAPPE 3.THE INVENTION IS RELATIVE TO A WRITING MACHINE INCLUDING A SINGLE MOTOR 16. THIS MOTOR 16 IS SERVICED BY A LOGIC CIRCUIT 62 DETERMINING THE DIRECTION AND AMPLITUDE OF THE ROTATION OF THE MOTOR SHAFT 17 FOR ALL THE ORDERS GIVEN ON THE KEYPAD 2. THE TWO ENDS OF THE DRIVE SHAFT 17 COOPERATE ALTERNATIVELY, THROUGH A FIRST SELECTION MECHANISM, WITH THE SELECTION SHAFT 6 AND WITH A DRIVE PULLEY 19. THIS LATEST 19 IS LIKELY TO DRIVE , THROUGH A SECOND SELECTION MECHANISM, EITHER MOVEMENTS OF TROLLEY 4 OR ROTATION OF PUNCHING CYLINDER 3.
