PROBLEM TO BE SOLVED: To provide a pachinko machine for lighting the same LED lamps in varying brightness. SOLUTION: Electric impressions IC75A, 75B impress an electric current to a plurality of LED lamps at different duty ratio. Resistors R1, R2 having different values are connected between the LED lamps and the electric impressions IC. Therefore the same LED lamps can be equivalently lighted in varying brightness.
