Abstract

Dispositif pour l'impression électrostatique à l'aide d'un rouleau d'impression rotatif muni d'électrodes en forme d'aiguille. Afin de maintenir petite la distance entre les images, les électrodes en forme d'aiguille sont mues transversalement à la direction longitudinale du porteur d'information en forme de bande. Simultanément, le porteur est transporté de façon continue De ce fait, on a supprimé le mouvement de translation du rouleau d'impression portant les électrodes. Application aux imprimantes rapides.
