PROBLEM TO BE SOLVED: To provide a game machine, always monitoring opening and closing of a member shielding a control device to quickly discover fraudulentness such as remodeling and replacement of the control device. SOLUTION: When an opening detecting sensor 45 detects opening of a game machine body 11, and outputs an opening signal, a first integrating part 55 and a second integrating part 75 integrate the count of outputting the opening signal, and stores the integrated value in a first integrated value storage part 52a of a main control board 40 and in a second integrated value storage part 72a of a sub-control board 41. When the game machine body 11 is closed and the output of the opening signal from the opening detecting sensor 45 is stopped, a determination part 56 compares the integrated values of the first integrated value storage part 52a and the second integrated value storage part 72a, and when the integrated values are determined to be a mismatch, an error processing part 57 conducts error processing.
