PROBLEM TO BE SOLVED: To provide a game machine which can effectively utilize all common lines. SOLUTION: This game machine is constituted by connecting all common lines 1 to 8 provided on a decorative control board 55 with either one of an LED 1A to an LED 13 of various lamps 201 to 205 provided on a display frame body 23. Thus, vacant common lines can be eliminated. Also, fraudulent signals can be prevented from being input from the vacant common lines. In addition, the common lines 1 and 6, the common lines 2 and 7, and the common lines 3 and 8 from among the eight common lines 1 to 8 provided on the decorative control board 55 are simultaneously turned on, and therefore, the turning-on frequency for respective common lines 1 to 8 becomes higher compared with the case where the eight common lines 1 to 8 are turned on in order one by one, and the luminous intensity of the LED 1A to the LED 13 which are connected with the common lines 1 to 8 can be increased.
