PROBLEM TO BE SOLVED: To prevent malfunction of an electronic control board due to the emitting of an interfering electric wave from outside a game machine and prevent illicit acquisition of coins or pachinko balls. SOLUTION: The game machine subjects a player's operating condition to electric conversion, uses an electronic control board 1 to determine if a game has been won, and provides a prize if winning requirements are met. Wiring cables 2A to 8A for connection to the electronic control board 1 are covered by transparent electromagnetic shield films 9 to 15 which allow visible rays to pass through.
