Abstract: A transmission line of a control signal to be transmitted from a main board to a peripheral board is trailed long inside a machine and thereby twisted to form a helically wound portion, so that L occurs in some cases. A microcomputer of a main board sends a control signal to a relay terminal board via a communication port. The relay terminal board provides a connection between a transmission line of the control signal from the main board and a transmission line from a peripheral board, thus transmitting to the peripheral board the control signal from the main board. Consequently, the transmission line of the control signal extended from the main board to the peripheral board is divided by the relay terminal board. Accordingly, the transmission line extended from the main board to the relay terminal board and the transmission line extended from the relay terminal board to the peripheral board are each made shorter than the related art transmission line connected from the main board to the peripheral board.
