<P>PROBLEM TO BE SOLVED: To obtain a game machine for suppressing deterioration in visibility of a game ball and preventing a fraudulent act for acquiring the game ball by applying radiowaves to a game board. <P>SOLUTION: A Pachinko machine 10 includes: a ball detection sensor 140 for detecting a game ball PB; the game board 22 for covering the ball detection sensor 140; and a radiowave shield 110 disposed between the ball detection sensor 140 and the game board 22 to absorb or reflect radiowaves. In this case, when unauthorized radiowaves are applied to the ball detection sensor 140 from a player's side, the unauthorized radiowaves are absorbed or reflected by the radiowave shield 110 and hence are attenuated. Further, visibility of the game ball PB is not deteriorated by the game board 22, and visibility of the radiowave shield 110 from the player is disabled by the game board 22, thereby suppressing deterioration of visibility in the game ball PB by the radiowave shield 110. <P>COPYRIGHT: (C)2012,JPO&INPIT |
