Abstract

Dispositif d'effacement de caractères dans une machine à écrire à mémoire. La machine à écrire comporte un clavier 12 à partir duquel sont entrés les signaux qui commandent la frappe des caractères par l'élément d'impression 15 ainsi que les mouvements du chariot 13 sur lequel l'élément d'impression est monté. Les signaux codés issus du clavier sont stockés dans une mémoire de ligne, qui peut être utilisée pour commander les corrections ultérieures. Lorsqu'un ordre de soulignement d'un caractère est entré sur le clavier, le code du caractère emmagasiné dans la mémoire est modifié de façon à indiquer, lors de la lecture de la mémoire que le caractère a été souligné et que, lors d'une opération d'effacement le caractère et son soulignement doivent être effacés.
