PROBLEM TO BE SOLVED: To provide a game machine capable of detecting fraudulent acts.SOLUTION: When fraudulent alteration of a DOOR terminal, such as a front surface frame is opened to an outer frame by some method, is performed to a magnetic detection switch 3024 and there occurs maintenance failure, such as coming-off of wiring (harness), fraudulent alteration of the magnetic detection switch 3024 and maintenance failure, such as coming-off of wiring (harness), can be detected and output difficulty notification based on a transmission path fraudulent alteration display command can be given by monitoring whether or not it is hard for the magnetic detection switch 3024 to output a signal communicating that a fraudulent act has been performed from an OUT terminal. When a result of monitoring by the magnetism detection switch 3024 communicates that a fraudulent act has been performed, it is possible to give abnormal magnetism occurrence notification based on a magnetic detection switch abnormality display command.SELECTED DRAWING: Figure 19 |
