PURPOSE: To conspicuously expand patterns by fitting pattern rotary plates drawing the winning patterns to the output shafts of at least two motors, and providing a lens device integrated with lenses expanding the patterns of the pattern rotary plates in the front of the pattern rotary plates. CONSTITUTION: An electric premium server device B is provided with pattern rotary plates 9-11 rotated by stepping motors 4-6. When the rotation of the stepping motors 4-6 is stopped by a control circuit and the prescribed winning patterns are stopped at the prescribed positions, attacker is opened as winning. A lens plate 17 for expanding the patterns of the pattern rotary plates 9-11 is provided with ring-like expansion lenses corresponding to the ring-like patterns of the pattern rotary plates 10, 11 and a half-ring-like expansion lens corresponding to nearly upper half of the pattern of the pattern rotary plate 9, and it is formed as an acrylic resin molding. The lens plate 17 is fitted to a game board by a decorative fitting plate 18. |
