Abstract

The object of the invention is to produce an image- changing electric sign containing a number of complete images where changing of the images can take place rapidly. This is achieved by dividing each complete image into a number of part images, having the images supported by a transparent readily flexible plastic film 11, on changing having a number of part images fastened on films each move only a small distance, by having behind each part image an arrangement consisting of transparent small rollers 15, 16 and arranging such illumination that the part images are illuminated uniformly from the rear so that it is hardly noticeable for an observer looking at a complete image that it is made up of part images. <IMAGE>
