PROBLEM TO BE SOLVED: To provide a game machine capable of properly improving accuracy of determining passing of a game medium.SOLUTION: A start pocket 84 is formed on a game board 80 of a Pachinko game machine. A game ball flowing into the start pocket 84 is guided through a guide path to the back of the game board 80. On a back surface side of the game board 80, a vertical path communicating with the guide path is provided. A first detection sensor and a second detection sensor are provided in the middle of a collection path. When the game ball is detected, game ball detection signals are output from the detection sensors to a main controller. The first detection sensor attenuates an alternating current change of high frequency signals when the game ball passes, and generates the game ball detection signals on the basis of the attenuation of the alternating current change. The second detection sensor attenuates the alternating current change of the high frequency signals when the game ball does not pass, and generates the game ball detection signals on the basis of the attenuation of the alternating current change. In reading the detection signals in the main controller, determination processing is performed to determine abnormal detection signals on the basis of the detection signals from the detection sensors. |
