PROBLEM TO BE SOLVED: To provide a game machine capable of making it difficult to read a control program and data stored in a storage means and preventing the production of a fraudulent chip. SOLUTION: The game machine comprises: a microcomputer incorporating the storage means connected to a CPU through address signals, data signals and control signals and an information output means for outputting at least a part of the address signals, the data signals and the control signals to the outside; at least one external device to which the information output means of the microcomputer is connected; and an information output setting means capable of executing setting regarding signal output of whether or not the information output means outputs the address signals, the data signals or the control signals to the outside of the microcomputer. Then, when the CPU accesses the storage means, the information output means does not output at least a part of the address signals, the data signals and the control signals to the outside of the microcomputer.
