PROBLEM TO BE SOLVED: To reinforce a power supply system in a slot machine. SOLUTION: The slot machine 1 comprises a main control board 92, a subordinate control board 94, reels 10a, 10b and 10c, a hopper device 78, a power supply unit 70, etc. inside a body part 2. The main control board 92 controls the start and stop of the reels 10a, 10b and 10c and the driving of the hopper device 78. The subordinate control board 94 controls reel lamps 144, etc. disposed on the inner side of the reels 10a, 10b and 10c. When a power switch 76 of the power supply unit 70 is turned on, the power of DC 24 V and 12 V is fed to the main control board 92, which converts the 12 V power supply to the 5 V power supply to be used for the operation of a CPU.
