<P>PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing the malfunction of means when signals are exchanged between a game control means and a game means. <P>SOLUTION: A variable prize-winning device 22 provided on a game board includes a large prize hole; an opening and closing door for opening and closing the large prize hole; and a variable prize-winning driving part 22c for operating the opening and closing door. The variable prize-winning device 22 includes a variable prize-winning detecting sensor 22e for detecting a game ball that has entered the large prize hole. The variable prize-winning device 22 is electrically connected to an MPU 82 of a main control board 81 through an interface circuit 93. The interface circuit 93 outputs a signal that indicates the occurrence of abnormal conditions to the MPU 82 when a detection signal from the variable prize-winning detecting sensor 22e is abnormal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
