Abstract:
1. An interface unit configured to interface a host unit with first and second peripheral units controlled by the host unit, the host unit including a first driver for driving the first peripheral unit and a second driver for driving the second peripheral unit, the interface unit comprising: a connector configured to be connected to any one of the first and second peripheral units; a first interface circuit configured to interface the host unit and the first peripheral unit; a second interface circuit configured to interface the host unit and the second peripheral unit; an identification circuit connected to the connector and configured to a host interface circuit configured to be connected to the host unit, wherein the first interface circuit is configured to interface the host unit and the first peripheral unit via the host interface circuit, when the first peripheral unit is connected to the connector and the host unit is connected to the host interface circuit, based on the first identification sequence instruction output by the identification circuit; and wherein the second interface circuit is configured to interface the host unit and the second peripheral unit via the host interface circuit, when the second peripheral unit is connected to the connector and the host unit is connected to the host interface circuit, based on the second identification sequence instruction output by the identification circuit; wherein when the first peripheral unit is connected to the connector, wherein when the second peripheral unit is connected to the connector, wherein said interface unit is external to each of the first peripheral unit and second peripheral unit.
