ABSTRACT:
A game of chance apparatus includes a rotatable symbol substrate driven relative to a marker by an electric motor. Teeth are mounted coaxially with the symbol substrate and have a tooth repetition equal to that of the symbols. The relative motion between the symbol substrate and the marker can be started or stopped by an electromagnet, the marker and the symbol substrate being lockable into predetermined relative positions by means of the teeth. To reduce operational energy consumption and impact stresses, two annular electromagnets are mounted concentrically to each other and coaxially with the shaft of the symbol substrate. The magnetizable marker is freely displaceable between the poles of the electromagnets. Rings which cannot be magnetized are mounted at a distance from each of the electromagnets between their poles and the associated ends of the marker. Both rings are so shaped and mounted that the marker rests against the ring associated with the energized electromagnet and upon contact with a ring engages the teeth.
