<p>A repeater has multiple operation terminal connections to which operation terminals are connected, multiple external memory device connections that are set in correspondence with the operation terminal connections and to which external memory devices are connected, and a main body connection terminal with which an electronic device main body is connected. The repeater makes possible communication between electronic device main body and connected operation terminals and external memory devices. An independent operation terminal communication system and an independent external memory device communication system are integrated into a main body connection terminal, hereby enabling simultaneous connection of such communication systems with the operation terminal connection and memory device connection on the electronic device main body.</p> |
