Abstract
Abstract An information storage and retrieval system includes a housing with a passage through it. A lens system is contained in the passage for projecting an image onto a microfiche portion positioned in register with the end of the passage. Electrodes are mounted in the passage for producing a corona discharge in the passage which charges the microfiche prior to its exposure to the image and toner is introduced into the passage after such exposure to develop the image on the microfiche portion.
