PROBLEM TO BE SOLVED: To provide a game machine capable of preventing unprepared detachment of a circuit board box from the rear side of a game board or mechanism board of the game machine. SOLUTION: When an accessory cover 9 is closed, engagement boards 9i and 9j of the accessory cover 9 are engaged with engagement holes 12d and 12e of a box cover 12b, and a main control circuit board box 12 is restricted from sliding/moving in the detaching direction relative to a main control circuit board box attaching base 14. As a result, the main control circuit board box 12 is located and restrained at a prescribed position relative to the main control circuit board box attaching base 14. When the main control circuit board box 12 is detached, the engagement between a pair of the engagement boards 9i, 9j and the engagement holes 12d, 12e is released by opening the accessory cover 9. However, as the main control circuit board box 12 cannot be detached from the main control circuit board box attaching base 14 while the accessory cover 9 is closed, unprepared detachment of the main control circuit board box 12 can be prevented.
