Abstract

Recording of documents such as large maps is effected on photographic strip using a sweep process. Reading is performed using a projector under electronic control with addressing information for the required image. An image is divided into several partial images and in recorded on film (F) wound on bobbins (1,2). For reading the film is driven by a toothed wheel (3) and step motors (4). A detector (5) detects the partial image number in a projection window (6). The number is compared (7) with that from a keyboard (8) and the difference between actual and required images and the direction of required motion are passed into circuits (8,9,14) to step the motor in the required direction.
