Abstract

Appareil de télécopie, notamment destiné à la transmission par câbles, d'informations écrites ou dessinées comprenant une tête pour la lecture ou l'écriture d'un document, munie de moyens de lecture ou d'écriture et un dispositif d'entraînement prévu pour faire balayer par la tête l'ensemble du document. Les moyens de lecture et d'écriture sont agencés pour travailler suivant un segment rectiligne s orienté perpendiculairement à l'une des dimensions du document 3; ce segment s a une longueur qui ne constitue qu'une fraction de l'autre dimension du document et le dispositif d'entraînement 4 comprend des moyens de déplacement de la tête 2 suivant une direction A perpendiculaire à s et des moyens 5 pour faire avancer pas à pas le document 3 à la fin de chaque balayage transversal, d'une longueur égale à s. Application aux télécopieurs destinés au grand public.
