Claim 11:
12. An electronic device comprising:
a first connecting wire to which a first signal wire is connectable, the first signal wire transmitting a first signal between the electronic device and an external device;
a first resistor disposed between the first connecting wire and a power source of the electronic device;
a second connecting wire to which a second signal wire is connectable, the second signal wire transmitting a second signal from the external device to the electronic device;
a third connecting wire that connects the first connecting wire and the second connecting wire to one another; and
a rectifying element connected to the third connecting wire,
wherein the rectifying element does not pass a current from the first connecting wire to the second connecting wire when a voltage of the power source is input to the second connecting wire via the first connecting wire and the external device in a state in which the first signal wire and the second signal wire are electrically connected to one another and the second signal is not input to the second signal wire from the external device.
