Abstract

L'invention concerne un lecteur de braille qui représente électroniquement l'écriture braille et des graphiques de points tactiles au moyen d'un support de représentation plan, doté de points saillants formés par des chevilles traversant de manière sélective des ouvertures dans la surface du support de représentation. Le support de représentation est constitué par une fine feuille métallique structurée et les chevilles (1) constituant les points saillants sont fixées dans la bande par des axes (2) et logées pivotantes, les signes à lire étant ainsi représentés par ouverture à la verticale (position tactile) ou abaissement à l'horizontale sous la surface (position non tactile) du support.
