PROBLEM TO BE SOLVED: To provide a game machine enabling simplification of the constitution of a power source device. SOLUTION: The power source device 24 is constituted of an AC conversion part 40 and a ground 41. When a main power source is turned on, the AC conversion part 40 converts an inputted AC voltage 24V into a DC voltage 12V. The converted voltage of 12V is supplied to each control circuit board through a distribution board 25. Each control circuit board is provided with a DC converter and thereby the voltage is converted into a working voltage (5V) of a control circuit and used. Besides, each control circuit board is fed with the voltage of 12V, not through the DC converter, and it is used as a driving voltage for each device. COPYRIGHT: (C)2004,JPO
