Abstract
L'invention est relative à un appareil photographique portatif permettant une photocopie électrostatique à la place d'une photographie. Une électrode 14 est située à l'avant de la surface, dans une position intermédiaire entre l'ouverture et la surface 12 pour charger électriquement ladite surface avant la formation de l'image optique sur elle. Application : photographie.
