PURPOSE:To prevent the malfunction of each control circuit from occurring due to the disturbance of a supply voltage supplied as a power source for each control circuit arranged in a pachinko machine by the influence of an electrostatic noise and to simplify the assembling of an electrical component. CONSTITUTION:A line noise erasure circuit 555 constituted by connecting plural capacitors in parallel is provided in a power supply circuit 55 for control circuit arranged in the pachinko machine. The electrostatic noise can be absorbed by the smoothing function of the plural capacitors connected in parallel, and a constant voltage on a power source supply line (554a) from which the power source is supplied to each control circuit arranged in the pachinko machine can be guaranteed. |
