<P>PROBLEM TO BE SOLVED: To prevent a fraud by surely detecting and notifying the fraud perpetrated when a door body is in an open state. <P>SOLUTION: This game machine includes a door opening sensor for detecting the state (an open state or a closed state) of a glass door frame, and respective winning switches (a count switch, a first operation-start hole switch, a second operation-start hole switch, and a winning hole switch) for detecting a game ball in each winning hole. This game machine determines that an abnormal win is produced based on the fact that one of the winning switches detects a game ball in a winning hole when the door opening sensor detects that the glass door frame is in an open state, and, performs control to output special sound for notifying the abnormal win based on the determination of the occurrence of the abnormal win. <P>COPYRIGHT: (C)2013,JPO&INPIT |
