Abstract
A system for providing a standard microfiche or similar reader with the capacity for making prints of the projected material without substantially modifying the reader is disclosed. A screen extension is provided having one end mountable to the face of the reader. The viewing screen of the reader is removed from its normal position and placed at the opposite end of the screen extension. The extension has a substantially light-impervious walled periphery which has an elongate narrow slot in one wall. A paper carrier is insertable through the slot in the periphery of the screen extension to a position adjacent the interior surface of the viewing screen. One side of the paper carrier is removable to expose light-sensitive paper in the carrier to the image projected by the reader. The system of the present invention also includes apparatus for supplying light-sensitive paper to the paper carrier and apparatus for developing the exposed light-sensitive paper.
