PROBLEM TO BE SOLVED: To provide a game machine less influenced by noise than a conventional machine. SOLUTION: A pachinko game machine 10 is composed of a main control board 31 and a display control board 32 electrically connected to each other and the display control board 32 and a voice control board 33 electrically connected to each other. Neither a GND line 51C for supplying power nor a GND line 51C for receiving/transmitting signals is connected between the main control board 31 and the voice control board 33. Hence an ordinary structure where GND lines 9Bg, 9Dg extended from the main control device 1 and the display control device 2 are connected to the voice control device 3 can be avoided and the number of GND loops can be reduced to make it less affected by the noise.
