Abstract

L'invention concerne les appareils de balayage optique Elle se rapporte à un dispositif dans lequel le faisceau laser 2 destiné à former la ligne de balayage 4 sous la commande du miroir rotatif 1, est intercepté par un modulateur 5 lorsque le faisceau 2 va parvenir sur le coin de la surface réfléchissante S1 , afin que ce coin ne reçoive pas de lumière et ne puisse pas perturber le balayage. Un détecteur 6 assure la synchronisation Application aux imprimantes à faisceau laser.
