Abstract

Dispositif de réglage pour la mise au point d'objectifs. L'objectif comprend un composant antérieur mobile en direction axiale. Ce composant est constitué par un groupe optique de lentilles 3 et par une monture 8 munie d'une cheville 9 qui, à travers une fente 11 d'un porte-objectif 10 vient s'engager dans une rainure de came 13 d'une bague de réglage 12 servant à la commande manuelle du dispositif. La cheville 9 est maintenue contre l'une des extrémités de la rainure 13 par un ressort 15 assurant l'assemblage d'une tige de guidage 14 assujettie à la monture 8 et d'un arbre d'entraînement 18 présentant un alésage cylindrique 19, par l'intermédiaire d'ergots 16 et 17. Une goupille 20 empêche la tige 14 de tourner. L arbre 18 présente une filetage 21 en prise avec un écrou 22 relié par un pignon 23 et un accouplement à friction 24, à un moteur 25 de commande automatique. Applicable au réglage de la mise au point d'objectifs.
