PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing variation in luminance of a backlight due to temperature change.SOLUTION: As a resistance value of a luminance adjustment volume SDVR0 is varied from a minimum resistance value to a maximum resistance value, an inclination of a characteristic curve of luminance of the backlight of a sub liquid crystal display device 3450 with respect to a variable operation of a luminance adjustment volume SDVR0 is minimized. Consequently even when a fixed resistance and the luminance adjustment volume SDVR0 are affected by a temperature, a resistance value of the luminance adjustment volume SDVR0 and the resistance value of the fixed resistance that have been adjusted by a worker of a manufacturer so as to become the luminance of the backlight of the sub liquid crystal display device 3450 in the shipping, are varied respectively, the variation of the luminance of the backlight of a sub liquid crystal display device 3450 with respect to a variation by variation in the resistance value can be minimized so as to suppress an increase in a variation of the luminance of the backlight of the sub liquid crystal display device 3450.SELECTED DRAWING: Figure 118 |
