PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing the number of using input ports to a number corresponding to the number of required switching stages and preventing the error of a setting operation as much as possible while using a general rotary switch having the number of contacts beyond need.SOLUTION: The game machine to which a rotary switch 44 having N pieces of contacts and having the output terminal of M bits corresponding to the N pieces of contacts is provided with a conversion circuit 45 for converting the output signals of M bits from the output terminal of the rotary switch 44 to M-1 bits and outputting them. The conversion circuit 45 is configured to output the OR of the most significant bit of the M bits and the other M-1 pieces of respective bits. |
