<p>A microfilm reader and printer (10) alternatively projects a magnified image of microfilmed information onto a rear-projection screen (14) for viewing or a photoreceptor belt (22) for printing. The projection screen (14) and the photoreceptor belt (22) are in parallel planes for convenient delivery of the printed image (18) and a movable mirror system (42) ensures that the printed image (18) will be of the same magnification as the viewed image.</p> |
