摘要:
A video signal and a control signal are converted into a radio frequency based on a radio communication method. This radio frequency is used to execute wired communications via one coaxial cable provided between a scope and a processor device. Furthermore, an electromagnetic coupling means composed of a primary coil and a secondary coil is provided between a connector and a light source device. The electromagnetic coupling means supplies power to the scope on the basis of electromagnetic induction. It is thus possible to connect the scope to both the processor device and the light source device using only two wires including a ground line. This makes it possible to prevent the inappropriate connection of or possible damage to connection pins or the like.
