PROBLEM TO BE SOLVED: To use a substrate case even if it is opened often by fixing the substrate case with a control board stored in the main body of the case to a game machine by inserting a screw into at least one installation section to secure the substrate case to the game machine through a corresponding fixation member. SOLUTION: Bases 20 are fixed to a game machine with the distance between the bases 20 same as the width of a substrate case 10. Then, a fixation member is inserted into a supporting section of the right base 20. A substrate and other components are stored in a case body 30 and the case body is closed with a case cover 40 to form the substrate case 10. The substrate case 10 is immovably disposed between the right and left bases 20 fixed to the game machine by engagement of engagement projections and engagement holes. Then a screw is inserted from an installation section 100 into a fixation hole 72 of a fixation section to fix the substrate case to the game machine. Thereby, the case cover 40 is fixed and the substrate inside the case cannot be touched. Accordingly, the substrate case can be continuously used even if it is opened after.
