PROBLEM TO BE SOLVED: To surely connect connectors of a board-side joint part in a game board side and a frame-side joint part in a front frame and prevent imperfect contact between both. SOLUTION: The frame-side joint part 48 which is electrically connected to an electric system in the side of the front frame 3 and has frame-side connectors 90-93, and a board-side joint part 47 which is electrically connected to an electric system in the side of the game board 9 and has board-side connectors 56-59 are provided in the front frame 3 and the game board 9 detachably mounted on a game board mount frame 8 of the front frame 3 respectively and, when the game board 9 is attached/detached with respect to the game board mount frame 8, the connectors 56-19 and 90-93 are mutually attached/detached corresponding to both the joint parts 47 and 48. The front frame 3 has an escape prevention section 74 allowing the game board 9 to receive the load applied to the frame-side joint part 48 and prevent the escape of the frame-side joint part 48, when the game board 9 is fitted into the game board mount frame 8.
