<P>PROBLEM TO BE SOLVED: To provide a game machine capable of improving ball entrance detection accuracy. <P>SOLUTION: Various kinds of ball entrance means such as general winning ports 31 and various kinds of ball entrance detection switches such as winning port switches 221 for detecting game balls that have entered the ball entrance means are arranged on the game board 30 of the Pachinko game machine. The winning port switches 221, etc., are connected to a main controller. A high level signal is output while game balls are not detected, and a low level signal is output while game balls are detected. On the other hand, the main controller periodically monitors signal levels to be input from the winning port switches 221, etc., and sequentially stores logical values corresponding to the signal levels. Then, the main controller performs the logical inversion processing of last data among previous three times worth of data that have been stored recently, calculates the logical products of all the logically inverted data and the other two times worth of data, and determines presence/absence of ball entrance in the general winning ports 31, etc., based on the calculation result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
