<P>PROBLEM TO BE SOLVED: To provide a game machine that prevents game balls from being illegally dispensed due to fraud using radio waves, etc. <P>SOLUTION: The game machine includes a play area, a game control device, and a ball detection means. The game machine further includes a fraud detecting means for outputting a fraud signal indicating that a fraud occurs, and the same clock signal as the a clock signal to be supplied to the game control means is supplied to the fraud detection means. The game control means executes an interruption process including an input process for obtaining a winning signal output from a detection information transmitting means and a fraud signal output from the fraud detecting means at predetermined time intervals based on the clock signal. The fraud detecting means is configured to detect whether a fraud state continues for a predetermined period of time or not based on the clock signal. The predetermined time required for the fraud detecting means to prescribe a condition for outputting a fraud signal is set shorter than the predetermined time when the interruption processing is executed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
