Abstract

Un procédé et un dispositif permettent de mesurer la longueur d'un objet et d'enregistrer sur celui-ci une valeur numérique. Un mouvement linéaire le long de la longueur à mesurer est converti en un mouvement rotatif par une roue rotative de mesure (11), ce mouvement rotatif étant converti à son tour en signaux électriques par un disque optiquement lisible. Les signaux électriques sont transmis à un ordinateur, où ils sont enregistrés. Le transfert se fait sans fils au moyen de diodes électroluminescentes (14). La longueur mesurée est marquée de manière durable sur ledit objet pendant l'étape de mesure et tous les articles présents sur ledit objet sont marqués de manière durable sur ledit objet pendant l'étape de mesure. A cet effet, le dispositif est pourvu d'un stylet (12) extensible et rétractile actionné par un dispositif d'actionnement (13) fonctionnellement connecté au commutateur électrique.
