Abstract
A worker selects at least one antenna in each of a video transmitter unit (20) and a display unit (30) with a remote controller (80). A selection signal, transmitted from the remote controller (80), feeds to light receiving means (69), (78) and passed on to microcomputers (67), (75). The microcomputers (67), (75) activate one of the antennas (26), (27) in wireless transmitting/receiving means (65) and one of the antennas (41), (42), (43) in wireless transmitting/receiving means (79), for which a selection instruction has been received.
