ABSTRACT:
The device exhibits images of products to be advertised mounted continually rotatable about axes arranged in a space in any manner, consisting of a supporting framework provided, at least at one end thereof, with a fixed element having an extended surface in transparent material, adapted to support images to be exhibited and, in a position facing the image-bearing element, with at least one rotatable element, bearing colors and other images, associated with a pivot freely rotatable on a support rigidly associated with the framework. The rotatable element is subject to continuous rotations alternating in both directions according to present angles, with respect to said fixed image-bearing element, by means of a miniaturized electronic circuit, independently powered by a battery and adapted to cause said pivot to rotate by magnetic repulsion between an intermittently powered coil and a permanent magnet.
