PROBLEM TO BE SOLVED: To provide a game machine which makes it possible to easily increase the capacity of a power supply to supply a predetermined apparatus to be controlled while suppressing the cost increase of the power supply apparatus. SOLUTION: Electric powers of 5V, 12V and 34V are supplied from the power output terminals of a power supply board. The capacity of the 12V power is set small and the capacity of the 34V power is set large. Power supply input terminals the number of which corresponds to the number of the power output terminals of the power supply board and power supply output terminals are fixed on each control board 13. Two or more control boards 13 are connected in series with the power output terminals of the power supply board. On the output terminals of the most downstream control board 13, a display control board 24 which controls a liquid crystal unit 25 using the power supply inputted in the power supply input terminals 24b is connected. If the consumed power of the liquid crystal unit 25 is small, the liquid crystal unit 25 is controlled with the 12V power supply without modification. If the consumed power of the liquid crystal unit 25 is large, a converting circuit which converts the 34V power supply to 12V power supply is fixed and the liquid crystal unit 25 is controlled with the converted 12V power supply.
