Abstract

Dispositif de mesure de longueur comportant une échelle disposée sur un support et dont la graduation est balayée par une unité de balayage, l'unité de balayage étant accouplée à un entraîneur raccordé à un objet à mesurer, et l'unité de balayage étant appliquée sur deux surfaces de guidage de l'échelle et/ou du support. L'unité de balayage 3 est, par l'intermédiaire d'un élément d'accouplement 6 rigide dans le sens de la mesure, accouplée de façon articulée à l'entraîneur 7 et la force de pression pour l'unité de balayage 3 sur deux surfaces de guidage 12, 14 de l'échelle 2 et/ou du support 1 est assurée au moyen chaque fois d'un ressort de pression 15, 16.
