ABSTRACT:
An interface unit for interfacing a host unit and first and second peripheral units includes a connector, an identification circuit, and first and second interface circuits. The connector is connected to any one of the first and second peripheral units. The identification circuit determines a type of peripheral unit connected to the connector. The first and second interface circuits interface the host unit with the first and second peripheral units, respectively, based on a result of the determination by the identification circuit. The identification circuit transmits a signal indicating the peripheral unit that is connected to the connector, to the corresponding interface circuit, and the corresponding interface circuit transmits a signal to the host unit, indicating that the corresponding peripheral unit is connected to the connector.
