PROBLEM TO BE SOLVED: To realize a pachinko machine wherein a data from a main control circuit and a command can be accurately inputted by means of a pattern displaying device. SOLUTION: When a main electric power source 70 is started up, a 5 V electric power source is fed to each board from a DC/DC converter 83 and when it reaches the lowest actuating voltage of an electric power source voltage monitoring IC 84, system reset signal are outputted in all the boards to stabilize them. Then, after the 5 V electric power source reaches an electric voltage Vus and a time Trs passes through, the system reset signals of sub-boards such as a special picture pattern control board sheet provided on a special picture pattern displaying device 32 are released to start respectively each of sub-boards. Then, a 12 V electric power source is fed to each of the boards from the DC/DC converter 82 and after the 12 V electric power source reaches an electric voltage Vuh and a time Trh passes through, a system reset signal of the payout control board 200 is released and after the 12 V electric power source reaches an electric voltage Vum and a time Trm passes through, a set system reset signal of a main board 100 is released.
