摘要

A worker selects at least one antenna for a video transmission unit (20) and a display unit (30) by means of a remote control (80). A selection signal sent out from the remote control (80) is received by light-receiving means (69, 78) and transmitted to microcomputers (67, 75). The microcomputers (67, 75) allow the selected and specified antennas to function, among the antennas (26, 27) of radio transmitting/receiving means (65) and the antennas (41, 42, 43) of radio transmitting/receiving means (79).
