PROBLEM TO BE SOLVED: To obtain a bus controller for reducing the number of pattern wirings to be connected to a connector by reducing the number of pins in the connector even when a device board is connected to a CPU board by using the connector. SOLUTION: A CPU 11 is connected to a device to be controlled 12 via a first bus 21 and a second bus 22. The CPU 11 is connected to a second device to be controlled 13 via the second bus 22. A switch 25 is inserted to a third bus 23 whose one end is connected to the first bus 21 and whose other end is connected to the second bus 22. Then a switch 26 is inserted to the second bus 22.
