PURPOSE: To conduct efficient information guidance by receiving, amplifying, waveform-shaping an infrared ray signal from an information transmission unit and calling an address so as to inform 3rd class guidance information to a recipient. CONSTITUTION: When a visitor enters a building, approaches an exhibit and enters a predetermined infrared ray area, an information reception unit 1B of the visitor uses a reception element 34 to receive an infrared ray signal from an information transmission unit 1A. The received signal is amplified by an amplifier 35 and waveform-shaped by a waveform shape section 36, a position information signal is decoded by a decoder 37 and an address included in the signal is called. Then a reproduction section 39 uses a chip select switch 38 to select 3rd class guidance information 1G and the selected information is transferred to a voice reproduction section 40, in which the information is amplified (41) and a reproduction device 42 outputs a sound of the 3rd class guidance information 1G to the visitor. When the explanation of the 3rd class guidance information 1G is finished, the reproduction control section 39 is in the standby state. |
