。[Claims for Utility Model Registration] (1) It has a connector for connecting an external device directly or via a cable, and a buffer with an enable terminal is inserted into the internal signal line connected to the connector. In the apparatus, the enable terminal is connected to a first terminal of the connector by a control line.
connecting the control line via a resistor to a first potential that connects to a terminal of the connector and disables the buffer, and connects a second potential that enables the buffer to a second terminal of the connector; . A buffer control device, wherein two terminals corresponding to the first and second terminals are connected in a connector of the external device or the cable coupled to the connector. (2) In a device that has a connector for connecting an external device directly or via a cable, and a buffer with an enable terminal is inserted into the internal signal line connected to the connector, the enable terminal is controlled. The control line is connected via a resistor to a first potential that is connected to the connector by a line and that disables the buffer, and a terminal of the external device connected to the control line is connected to a first potential that enables the buffer. A buffer control device characterized in that it is connected to a second potential.
