PROBLEM TO BE SOLVED: To provide a device for detecting that a game ball is operated by a magnetic field generator such as a permanent magnet and further that the game ball is fraudulently guided to a winning hole during the play in a game machine such as a Pachinko machine. SOLUTION: The device has a structure in which a pair of conductive faces are disposed face to face on a game board surface side of a transparent plate disposed on the front surface of the game machine. A spacer is inserted between the conductive faces, and a touch sensor with light permeability is also disposed. When a player attracts a game ball with a magnetic field generated from a permanent magnet, etc. through the transparent plate on the front surface of the game machine, the game ball is pressed on the transparent plate on the side where the touch sensor is disposed, so that the pair of conductive faces within the touch sensor conduct with each other. By extracting the conduction as an electric signal, the fraudulent operation of the game ball can be detected. COPYRIGHT: (C)2011,JPO&INPIT |
