<P>PROBLEM TO BE SOLVED: To provide a game machine capable of preventing fraudulence in an radio-wave hopper. <P>SOLUTION: A hopper device 60 includes: a tank 61 in which a plurality of tokens can be stored; a discharge device 63 for discharging the tokens inside the tank 61 from an outlet 64; and two discharge sensors for detecting discharged tokens from the outlet 64. The voltage level of a signal of a first discharge sensor 81 is low and the voltage level of a signal of a second discharge sensor 82 is high while the operation of the discharge device 63 is stopped. The voltage level of the signal of the first discharge sensor 81 becomes high and the voltage level of the signal of the second discharge sensor 82 becomes low whenever one token is discharged from the outlet 64 according to the operation of the discharge device 63. If a state in which the voltage levels of signals of both the first discharge sensor 81 and the second discharge sensor 82 are high continues for a prescribed period of time, it is determined that an abnormality occurs in the hopper device 60. <P>COPYRIGHT: (C)2013,JPO&INPIT |
