PROBLEM TO BE SOLVED: To efficiently confirm whether the contents of data stored in a data memory medium mounted on a circuit board are correct or not in a game machine such as a pachinko game machine and a slot machine. SOLUTION: When data memory media 124-1 to 124-3 are properly mounted on the circuit board, their respective head addresses are X, Y and Z. Test data set so that the total values are X, Y and Z are stored in the addresses with a, b and c added to the head addresses respectively. In checking the data, the whole test data are added in the data memory media 124-1 to 124-3 mounted on the circuit board respectively. If the result of the addition is neither X, Y nor Z, it is determined that the contents of data of the data memory media 124-1 to 124-3 mounted on the circuit board are incorrect.
