<P>PROBLEM TO BE SOLVED: To provide a game machine capable of preventing an illegal act based on radiowave or the like and erroneous put-out of balls caused by a contact failure of a signal line. <P>SOLUTION: The game machine includes a relay board for relaying signals between a ball detecting means and a game control device. The game control device includes a game control means for controlling games in general, and a detected information transmitting means for outputting, to the game control means, a prize winning signal that can specify whether a game ball has entered a winning pocket based on a voltage level outputted from the ball detecting means. A pull-up resistance for applying a predetermined voltage to the ball detecting means is connected to signal wiring for connecting the ball detecting means to the game control means, and a pull-down resistance for holding a voltage level inputted to the detected information transmitting means when electrical connection is cut off, to a voltage level on which no game ball is detected, is connected to signal wiring for connecting the relay board to the detected information transmitting means. The pull-up resistance is disposed at the relay board, and the pull-down resistance is disposed at the game control device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
