1. A communication device comprising:
a voltage detector configured to detect a voltage from a first signal line to which the communication device and a master device are connected; and
a controller configured to output, in case of detecting a read-out command from a second signal line to which the communication device and the master device are connected, a first signal with a time length corresponding to a value of the voltage to a third signal line to which the communication device and the master device are connected, and
output, in case that a first signal is not detected on the third signal line from another communication device different from the master device after output of the first signal ends, a second signal including information corresponding to the read-out command to the second signal line.
