Abstract

L'invention concerne un codeur optique. Elle se rapporte à un codeur optique dans lequel une source lumineuse 35 transmet un faisceau 45 à un élément 19 qui comprend deux branches 51 et 53 qui divisent le faisceau en deux faisceaux séparés qui sont renvoyés par des groupes de fentes 75 et 77 d'un disque fixe 21 et des fentes d'un autre disque rotatif 23, vers des photodétecteurs 37 et 39. Application au codage de la position des moteurs d'entraînement des têtes d'impression par gouttelettes d'encre.
