摘要

PROBLEM TO BE SOLVED: To detect fraudulent actions and the malfunctions of a game machine due to the exchange of a regular main control board of the game machine with a fraudulent main control board or the like, and to reduce the processing loads of the CPU of a peripheral part. SOLUTION: The main control part 10 of a Pachinko game machine includes an individual inspection value generation means 13 for generating an individual inspection value by dividing predetermined data inside a data storage means 11 and performing a dyadic operation, a synchronous code generation means 14 for generating a synchronous code using the packet information of a kind based on a division number, and a time code generation means 15 for generating a time code, and transmits the individual inspection value, the synchronous code and the time code to the intermediate part 20. The intermediate part 20 includes an individual authentication means 22 for authenticating the normality of the individual of the main control part 10 when an operation value obtained by performing the dyadic operation to the predetermined data and a value obtained by performing connection processing to the individual inspection value coincide, and an operation authentication means 23 for specifying the kind of the packet information on the basis of the number of the individual inspection values and authenticating the continuity of the operation of the main control part 10 using the packet information and the time code.
