Abstract

Le dispositif comprend une pièce mécanique (52) par rapport à une référence fixe (63), caractérisé en ce qu'il comprend une pièce mécanique (52) mobile par rapport à une pièce de référence fixe (63), une cellule (64) émettrice d'un faisceau lumineux conique (67) fixée à une partie fixe (65), ce faisceau lumineux conique (67) étant dirigé vers la pièce de référence fixe (63) et vers un récepteur (66) disposé en regard de la face de la pièce de référence fixe (63) opposée à la cellule (64), mais susceptible de capter la partie du faisceau lumineux conique (67), qui n'est pas masquée par la pièce de référence (63), la pièce mécanique mobile (52) comportant une partie (68) susceptible de couper le faisceau lumineux conique (67) lorsqu'elle est dans la position à contrôler en regard du récepteur (66) à la limite du recouvrement avec la pièce de référence fixe (63).
