PURPOSE:To eliminate the no-termination condition of a peripheral equipment interface and to prevent malfunction of an peripheral equipment by providing the pull-up resistance for assuring the voltage of a peripheral equipment receiving line in the peripheral equipment and executing the termination of the peripheral equipment interface by a terminating unit connected to an extension connector. CONSTITUTION:Peripheral equipment receiving lines 16, 17 and 18 are inputted through a peripheral equipment interface connector 11 to the peripheral equipment 4, and respective lines are pulled up to a positive voltage 26 by pull-up resistances 20, 21 and 22 for assuring the voltage. Further, the lines are inputted through an extension connector 14 to a terminating unit 15, and in the terminating unit 15, respective lines are connected to the positive voltage 26 outputted from the peripheral equipment 4 through terminating resistances 23, 24 and 25. An peripheral equipment transmitting line 19 is connected from the peripheral equipment 4 through the peripheral equipment interface connector 11 and an extension connector 13 to a connecting cable 7 of the peripheral equipment interface.
