Abstract

L'invention concerne un stylo d'observation automatique de pupille, comprenant un corps de stylo d'observation (1). Deux rainures fixes (2) sont formées dans le fond du corps de stylo d'observation (1). Une colonne rotative (3) est montée à rotation dans chacune des deux rainures fixes (2). Une extrémité de chacune des deux colonnes rotatives (3) est pourvue d'une rainure mobile (4). Une colonne mobile (5) est montée de manière coulissante dans chacune des deux rainures mobiles (4). Une plaque support (6) est reliée de manière fixe à une extrémité de chacune des deux colonnes mobiles (5). Une rainure filetée est formée dans l'autre extrémité de chacune des deux colonnes mobiles (5). Une rainure de commande est formée dans la paroi interne d'un côté de chacune des deux rainures mobiles (4). Une vis-mère (7) est monté à rotation dans chacune des deux rainures de commande, les vis-mères (7) étant montées dans les rainures filetées correspondantes dans un mode vissé. Un premier engrenage conique (8) est emmanché de manière fixe sur chacune des deux vis-mère (7). Un trou de rotation est formé dans la paroi interne d'un côté de chacune des deux rainures de commande. Une tige rotative (16) est montée à rotation dans chacun des deux trous de rotation. Un deuxième engrenage conique (9) est relié de manière fixe à une extrémité de chacune des deux tiges rotatives (16), les deuxièmes engrenages coniques (9) étant en prise avec les premiers engrenages coniques correspondants (8). Une roue de commande (10) est reliée de manière fixe à l'autre extrémité de chacune des deux tiges rotatives (16). Le stylo d'observation automatique de pupille selon l'invention permet de soutenir une position d'utilisation, de sorte que les secousses sont évitées pendant l'utilisation et la précision de détection est garantie.
