<P>PROBLEM TO BE SOLVED: To provide a pinball game machine for preventing damage in a game hall in advance by appropriately detecting a fraudulent act of radio fraud. <P>SOLUTION: The pinball game machine includes a switch data buffer for storing, for a prescribed period, a nondetection state or a detected state of a proximity switch disposed at a winning hole to be detected each time when fixed time interrupting processing is executed. The pinball game machine determines that a prize has been won when the lower three bits of the switch data buffer indicates a switch data detection pattern "011" indicating a state a detection state "1" has been maintained once after changing from a nondetection state "0" to a detection state "1" and determines that the error 1 has resulted when the lower three bits indicate "010", namely a state changed to the nondetection state "0" without maintaining the detection state "1" after changing from the nondetection state "0" to the detection state "1" and when the lower four bits of the switch data buffer are "0110" indicating a state changed to the nondetection state "0" after maintaining the detection state "1" once after changing from the nondetection state "0" to the detection state "1". <P>COPYRIGHT: (C)2012,JPO&INPIT |
