In addition, bar codes to code the frequencies used for transmission are provided to the respective endoscopes, the bar code provided to the endoscope used in endoscope inspection is read on a receiver side, and a reception frequency of a station selection unit is set to the read frequency, so that a signal obtained by a desired endoscope can be easily received and imaged even in case a plurality of endoscopes are used.
