<p><P>PROBLEM TO BE SOLVED: To provide a game machine which can correct an error even if the error occurs in an instruction signal transmitted by one-way serial transmission system communication from a main control board to a sub-control board. <P>SOLUTION: Every time two instruction signals are continuously outputted from the main control board 2A, the game machine is provided with: a revision signal calculation means 44 to execute prescribed calculation on the two instruction signals to calculate a revision signal; and a transmission control part 45 to sequentially transmit the two instruction signals and the revision signal. Then, parity check is executed at a reception circuit side, and when an error is found out in one of the two instruction signals, the other of the two instruction signals is subtracted from the revision signal to generate a correction signal and the erroneous instruction signal is replaced with the correction signal. Thereby, even if the errors occur in the transmitted instruction signals when the instruction signals are transmitted in one-way serial transmission system communication, an error bit can be corrected. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
