<P>PROBLEM TO BE SOLVED: To prevent a foul ball collection passage from being illegally used for fraud. <P>SOLUTION: A foul ball collection passage (hereinafter referred to as a passage) 80 is provided to lead to a ball tray. The passage is designed to guide a Pachinko ball to the ball tray so as to be used for a game when the Pachinko ball launched to the game region of a game machine does not reach the game region. Along the passage 80, a stop valve 102 is installed which is displaced in a closing position for closing the passage 80 and in an opening position for opening the passage and which is biased to the closing position. An open regulation part 85 is installed which regulates the opening operation of the stop valve 102 from the downstream to the upstream side of the passage 80 across the stop valve 102. Thus, the open regulation part is configured to displace the stop valve 102 from the closing position to the opening position, when it is pressurized by the Pachinko ball flowing down the passage 80. <P>COPYRIGHT: (C)2013,JPO&INPIT |
