PROBLEM TO BE SOLVED: To provide a game machine that can prevent light likely to hamper more correct detection from entering a light receiving section of a detector by a simple configuration.SOLUTION: Infrared light from a light emission section 42 of a motion sensor 172 is optically stopped down by a light emission diaphragm section 52 of a sensor table 50 with a smaller aperture area than the light emission section 42. That is, after an infrared luminous flux from the light emission section 42 is narrowly stopped down by the light emission diaphragm section 52 with depth, light is emitted from a cover member 60, thereby reducing adverse optical effects on other motion sensors. In addition, infrared light arriving at a light receiving section 43 of the motion sensor 172 is narrowly stopped down by passing the infrared light through a light receiving diaphragm section 53 of the sensor table 50 in advance. Thus infrared light from the other motion sensors is prevented from arriving at the light receiving section 43 of the motion sensor 172. |
