<p>It consists of a dihedral support (7) equipped with a large circular window (8), extended through the two faces of the support (7), immediately behind which is established a disc (1), of flexible transparent or translucid plastic, provided at its circumference with an alignment of images (2), participating in the machine game, such that said disc (1) is retained by the support (7) across its circumference, being interlocked through its center to the shaft (3) of an electric motor, preferably a step to step synchronous motor, suitably controlled by means of, for example, a phototransmitter-receiver, such that in the rotational movement of said motor, supplied to the image carrying disc (1), said disc permanently maintains a dihedral configuration, due to its flexible nature, showing the observer an alignment of images (2) according to a circumference arc of variable amplitude, according to the level of concealment of the front face of the assembly. The disc is susceptible of also being applicable to several machines, permitting that in all of them, the corresponding images are offered, through their respective windows arranged in the front of each one of the machines. If the disc is applicable to several machines simultaneously, it should be equipped with two bracings near and parallel to each one of its diameters, to determine two almost semicircular sectors, one in the front and the other in the rear, whilst across the intermediate sector the assembly is installed over the corresponding furniture. <IMAGE></p> |
