Abstract

Projecteur à double ensembles optiques permettant de projeter des diapositives en fondu-enchaîne, en relief stéréoscopique et en panoramique double largeur. Il fonctionne avec un magasin distributeur récupérateur de diapositives unique dans lequel les diapositives sont classées dans le même ordre que pour les passer dans un projecteur mono-objectif. Il comprend quatre couloirs glissières à diapositives parallèles entre eux et transversaux aux axes de deux ensembles optiques dans lesquels les diapositives circulent par paire. Ces couloirs sont prolongés d'un aiguillage dont le rôle est de faire passer les diapositives déjà projetées, des couloirs d'aller, dans des couloirs de retour, et ainsi faire rentrer les diapositives dans la même case du même magasin dont elles étaient sorties. Ces déplacements sont possibles grâce à un récupérateur à fonctions multiples. Simultanément au déplacement du récupérateur, un potentiomètre double en relation avec un dispositif électronique réalise le fondu-enchaîné. Ce projecteur peut être employé en projection simple, mais sans trou noir entre deux passages de diapositives, en relief stéréoscopique, et en panoramique double largeur.
