<p>The device exhibits images of products to be advertised mounted continually rotatable about axes (13) arranged in a space in any manner, consisting of a supporting framework (12) 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 (4a,4b), bearing colors and other images, associated with a pivot (13) freely rotatable on a support (3a,3b) rigidly associated with the framework (12). The rotatable element (4a,4b) is subject to continuous rotations alternating in both directions according to preset angles, with respect to said fixed image-bearing element, by means of a miniaturized electronic circuit (6,9), independently powered by a battery (8) and adapted to cause said pivot to rotate by magnetic repulsion between an intermittently powered coil (6) and a permanent magnet (9).</p> |
