PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a fraudulent act of changing a game content by misappropriating a game machine board box and, if such a fraudulent act occurs, discovering the fraudulent act at an early stage.SOLUTION: A case 50 of a fitting member 2 and a fitting projection 60 are attached to side walls of a box body 41 and a box lid body 42, respectively. The fitting projection 60 is arranged at a position corresponding to a fitting recess 53 provided in the case 50. Thus, when the box body 41 is covered by the box lid body 42, the fitting projection 60 is fitted to the fitting recess 53, and a circuit board can be accommodated by the box body 41 and the box lid body 42. Meantime, a box lid body used in another model has a different arrangement position of the fitting projection and cannot be installed to cover the box body 41. This prevents a fraudulent act of misappropriating the box body or the box lid body used in another model.SELECTED DRAWING: Figure 6 |
