PROBLEM TO BE SOLVED: To stably detect fraudulence using a magnet without impairing the visibility of a game area in a game machine, and to improve the efficiency in the work of attaching a transparent glass plate.SOLUTION: The game machine 1 includes a front frame member 3 with a window 5 through which the game area is visible, and a transparent plate unit 4 to be detachably attached to the window 5. The transparent plate unit 4 includes a coil 8 wound around the periphery of the game area, and distance sensors 9a and 9b for measuring the distance to an article present near the front surface of the transparent plate unit 4. Fraudulence is detected on condition that variation in the magnetism is detected by the coil 8 and that the article in a prescribed area is detected based on the result of measurement by the distance sensors 9a and 9b. Connectors 45 and 48 are disposed in the transparent plate unit 4 and the front frame member 3 respectively. The connectors 45 and 48 are connected to each other as the transparent plate unit 4 is attached to the window 5. |
