Abstract

La présente invention concerne un coupleur optique pour dispositif de commande à calculateur. Dans un dispositif de commande 20 comprenant un module d'unité centrale 120 pour commander les registres de commande d'une machine hôte externe 30 par l'intermédiaire d'un câble blindé, un isolateur est interposé pour éliminer sensiblement les signaux de bruit induits En particulier, l'isolateur est constitué d'un premier émetteur dans la machine hôte pour accepter les signaux en provenance des registres de commande adjacents et pour envoyer ces signaux sur le câble vers le dispositif de commande électromagnétiquement blindé spatialement éloigné. Application à la commande par ordinateur d'un photocopieur.
