Abstract

L'invention est relative à un appareil de mesure de longueurs. Dans l'appareil, qui comporte une règle incrémentielle sur laquelle se déplace un chariot, il est prevu, sur ledit chariot, deux groupes de photo-transistors explorant la règle, tandis qu'un commutateur pouvant être actionné par le chariot fait passer le groupe d'exploration de la région de raccordement à l'autre groupe. L'appareil, exempt d'usure, présente une précision élevée.
