PROBLEM TO BE SOLVED: To provide a new magnetism detection system for game machine which can flexibly correspond to an increase or decrease in number of magnetic sensors and can simplify a processing circuit as well. SOLUTION: The magnetism detection system for game machine includes: a magnetism detection portion having a plurality of magnetic sensor modules respectively arranged in prescribed positions of a game board; and a disconnection-magnetism determination portion determining disconnection or the presence or absence of magnetism by a voltage outputted from the magnetism detection portion. The magnetism detection portion outputs and supplies a power source when not detecting the disconnection or the magnetism, and does not output or supply the power source when detecting the disconnection or the magnetism. The disconnection-magnetism determination portion determines to be normal when the power source is outputted and supplied from the magnetism detection portion, and determines to be abnormal when the power source is not outputted or supplied from the magnetism detection portion. Thus, it is made possible to flexibly respond to the increase or decrease in the number of magnetic sensors and simplify the processing circuit as well. COPYRIGHT: (C)2011,JPO&INPIT |
