PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a wrong replacement board which does not correspond to specifications from being housed in a board case as a replacement board replaceable in accordance with the specifications of the electric component.SOLUTION: When a 12"-compatible second connection board 82 is mounted to a 12"-compatible cover member 802, a first protrusion 845 and a second protrusion 846 are fitted respectively into a first fitting hole 855 and a second fitting hole 856, and thus a base member can be closed by the cover member 802. However, a 15"-compatible second connection board 82A is attempted to be mounted to the 12"-compatible cover member 802, a first protrusion 845A and a second protrusion 846A are not fitted respectively into a first fitting hole 855A and ta second fitting hole 856A, and the base member cannot be closed by the cover member 802, so that the second connection board 82A of different specifications can be prevented from being housed in a board storage case inadvertently. |
