Abstract

L'invention concerne un dispositif indicateur optique numérique permettant d'indiquer la position d'un organe mobiie de mesure par rapport à la position de repos à l'aide d'une plaque de codage qui peut être déviée essentiellement proportionnellement par l'organe de mesure et qui comporte un modèle de codage pourvu de zones opaques et transparentes qui sont éclairées par une source lumineuse fixe sur un côté de la plaque alors que sur l'autre côté sont disposées les entrées de conducteurs de lumière qui éclairent en correspondance au modèle de codage un indicateur à sept segments. Dans ce dispositif, la plage de codage est associée à un verrou magnétique comportant des positions d'arrêt correspondant positions relatives déterminées alors que tous les autres organes optiques sont fixes, et il est prévu entre l'organe de mesure et la plaque de codage un accouplement élastiquement flexible et situe à l'intérieur d'un échelon d'arrêt magnétique. Indicateur optique numérique.
