PROBLEM TO BE SOLVED: To examine whether a control board and a semiconductor component are fraudulently exchanged or not. SOLUTION: Board identification information stored in a board management chip 9 provided in the control board 2 of a game machine is read by a board reader 5, while component identification information stored in a ROM of the semiconductor component 4 mounted on the control board 2 is read by a component reader 6. A determination means 7 collates the read board identification information and the read component identification information with set identification information set in the determination means 7, and when the set of the read board identification information and the read component identification information is accorded with the set identification information, it determines that the control board 2 and the semiconductor component 4 are a regular set. When the set of the read board identification information and the read component identification information is different from the set identification information, the determination means determines that either of the control board 2 or the semiconductor component 4 is fraudulently exchanged.
