PURPOSE:To expedite the operation of transmitting data between a plurality of control circuits and one console by connecting a circuit for converting a series transmission signal from the console to a parallel transmission signal to a common bus and providing a switchover circuit between this circuit and a plurality of control circuits. CONSTITUTION:At the time of transmitting data to a specific control circuit out of a plurality of control circuits, the specific control circuit 12a or 12b is connected to a series-parallel converting circuit 3c by the operation of a switchover circuit 15. When series transmission signals from a console are inputted into the series-parallel converting circuit 3c, a detecting signal for detecting the input is inputted into the specific control circuit 12a or 12b via the switchover circuit 15. Thereby, the specific control circuit 12a or 12b can access a data inputted into the series-parallel converting circuit 3c to carry out necessary processing. |
