PROBLEM TO BE SOLVED: To allow individual electric component control means to reliably receive commands and to reduce the program capacity of a game control means. SOLUTION: The game control means turns on an INT signal indicating a data output after a period A elapses and turns off the INT signal after a period B elapses thereafter. If there are data to be transmitted next, the game control means outputs the data at the second byte to an output port after a period C elapses. The period C is set so that a control means on the reception side can reliably receive data, and the period C is set longer than the receiving process time in the electric component control means requiring the longest time for the command receiving process.
