PROBLEM TO BE SOLVED: To reduce a production cost and to prolong the life of a circuit board by commonly using a power source circuit among various models. SOLUTION: The power source circuit 152 which forms various DC voltages is mounted at the power source circuit board 150. The electric power to be supplied to the respective circuit boards is supplied via a power source switch 15. DC 30 V and DC 12 V are supplied to the main control circuit board 31. DC 30 V, DC 21 V and DC 12 V are supplied to the lamp control circuit board 35. DC 30 V and DC 12 V are supplied to the prize ball circuit board 37. DC 12 V is supplied to the voice control circuit board 70. DC 30 V and DC 12 V are supplied to the shooting control circuit board 91. DC 30 V and DC 5 V are supplied via the main control circuit board 31 to the display control circuit board 80. The DC 5 V to be supplied to the display control circuit board 80 is formed in the main control circuit board 31 as described afterward.
