Abstract

L'INVENTION EST RELATIVE A UN MECANISME D'IMPRESSION COMPRENANT UN DISQUE 6 DE CARACTERES 8 DESTINES A ENTRER SELECTIVEMENT EN CONTACT AVEC UN CYLINDRE DE FRAPPE 5 SOUS L'ACTION D'UN MARTEAU 11. CE MARTEAU 11 EST LANCE PAR UN DISPOSITIF DE FRAPPE 13, 17-19 CONTRE L'ACTION D'UN RESSORT DE RAPPEL 16 POUR ETRE ANIME D'UNE VITESSE PROGRESSIVEMENT CROISSANTE, PUIS DECROISSANTE, DANS SES DEPLACEMENTS EN DIRECTION DE LA SURFACE D'ECRITURE 5. EN VUE D'OBTENIR UNE FORCE DE FRAPPE ADAPTEE A LA SURFACE D'IMPRESSION DE CHAQUE CARACTERE 8, LE DOS DU CORPS 20 DE CHAQUE CARACTERE 8 EST MUNI D'UN TALON 21 DESTINE A COOPERER AVEC LE MARTEAU 11 ET DONT L'EPAISSEUR EST PROPORTIONNELLE A LA SURFACE D'IMPRESSION DE CE CARACTERE 3. IL EN RESULTE QUE LA VITESSE DU MARTEAU 11, LORS DE LA FRAPPE, EST D'AUTANT PLUS GRANDE QUE LE TALON 21 EST EPAIS, DONC QUE LA SURFACE D'IMPRESSION DU CARACTERE 8 EST GRANDE.
