PROBLEM TO BE SOLVED: To prevent data from the transmitting end from being erroneously transmitted to the receiving end by noise. SOLUTION: This game machine is equipped with a transmitter to transmit data and a receiver to receive the data sent from the transmitter. The transmitter has a signal outputting means to output a signal to a receiver 71 and a data outputting means to output data to the receiver 71. The receiver 71 is equipped with a first signal receiving means 74 to receive a signal outputted from the signal outputting means as an interrupting signal and a second signal receiving means 76 to receive a signal outputted from the signal outputting means as an ordinary signal. When a signal is received by the first signal receiving means 74, the receiver 71 judges the validity of data transmitted from the transmitter based on a signal receiving condition of the second signal receiving means 76.
