PROBLEM TO BE SOLVED: To provide a game machine whose substrate has features.SOLUTION: A first driver 739 controls a light emission operation of "R" in a full color LED 743, and also controls light emission operations of "R", "G", and "B" in a full color LED 749. A second driver 741 controls light emission operations of "G" and "B" in the full color LED 743, and also controls light emission operations of "R", "G", and "B" in a full color LED 755. The full color LED 743 is mounted on a light emission board 861 where the full color LED 749 is mounted. As the full color LED 743 and the full color LED 749 are mounted on the same light emission board 861, it becomes easy to compare the full color LED 743 to the full color LED 749, which makes it easy to find abnormalities. |
