A bidirectional communication device for an electronic endoscope provided with a videoscope having an imaging function and generating a scope information signal, has a communication channel, a first communication circuit and a second communication circuit. The first communication circuit outputs a clock signal to the communication channel in order to perform the imaging function in the videoscope. The second communication circuit receives the clock signal through the communication channel and amplifies the clock signal to generate an amplified clock signal. The second communication circuit superimposes the scope information signal onto the amplified clock signal to generate a superimposed signal, which is transmitted to the first communication circuit through the communication channel. The first communication circuit obtains the scope information signal from the superimposed signal at a timing corresponding to the clock signal.
