Abstract

L'invention concerne un appareil de balayage optique. Elle se rapporte à un appareil de balayage dans lequel un miroir 2 doit se déplacer en translation deux fois plus lentement qu'un miroir 1. Selon l'invention, un fil 69 passe sur deux poulies fixes 63 et 65 et sur deux poulies mobiles 57 et 59 portées par le chariot du miroir 2. Le fil est fixé d'une part sur le chariot du miroir 1 et d'autre part sur un organe fixe de la machine. Application aux appareils de reprographie.
