Abstract

Machine à copier à agrandissement variable. Elle comporte un fil métallique dont une extrémité est fixée au corps de la machine et dont l'autre extrémité est fixée à un élément mis en rotation lorsque deux réflecteurs sont avancés pour balayer optiquement un original placé sur un chariot. Les deux réflecteurs sont montés chacun sur un support guidé de manière à pouvoir se déplacer parallèlement au chariot. Domaine d'application : machines à copier, à photocopier, etc.
