PROBLEM TO BE SOLVED: To provide a transmitter-receiver that surely attain transmission reception without causing crosstalk even when a receiver installed in two or more transmission reception areas simultaneously receives signals from a plurality of transmitters. SOLUTION: Each of a plurality of transmitters 12(121 -12n ) connecting to a signal generator 11 via cables 171 -17n is provided with each of delay circuits 18(181 -18n ) to adjust a time delay of a transmission signal from the transmitters 12, wherein delay time adjustment elements 321 -32n of the delay circuits 18 adjust the delay time in a way that a transmission timing of other transmitters 12 is matched with a transmitter 12 having a largest signal delay. Since each transmission timing of the signals sent from each transmitter 12 is matched by the delay circuit built in each transmitter 12, a signal sent from any transmitter 12 is received by any of the receivers 14(141 -14n ) without crosstalk. Even any of the receiver 14 is moved within the transmission reception areas 161 -16n of any transmitter 12, the receiver 14 receives the signal. |
