Claim 10:
11. The communication device of claim 10, further comprising:
a first resistor and a second resistor connected to the power line; and
a first inverter and a second inverter,
wherein the control circuit is an AND logic circuit comprising a first input terminal, a second input terminal, and a third input terminal,
wherein the first input terminal of the control circuit is connected to the signal line,
wherein the second input terminal of the control circuit is connected, through the first inverter, to the first resistor connected to the power line and to the first conductor,
wherein the second input terminal of the control circuit is connected, through the second inverter, to the second resistor connected to the power line and to the third conductor, and
wherein the control circuit is configured to:
receive the first signal from the processor of the external electronic device through the first input terminal,
receive, through the second input terminal, the second signal of a high level that is generated from the first inverter by discharging the power flowing along the power line to the ground through the first resistor, the first conductor, and the at least one second conductor when the first conductor is electrically connected to the at least one second conductor, and
receive, through the second input terminal, the third signal of a high level that is generated from the second inverter by discharging the power flowing along the power line to the ground through the second resistor, the third conductor, and the at least one fourth conductor when the third conductor is electrically connected to the at least one fourth conductor.
