PURPOSE:To reduce deterioration in transmission as much as possible by synchronizing a transmitted signal with a signal to be transmitted. CONSTITUTION:A transmission signal identifying part 6 detects whether a signal from a reception part 5 is a transmission signal or not, and stores this transmission signal in a memory temporarily. Further, a signal end detection part 8 detects the end of the transmission signal from the reception part 5 and counts a stop period 2T after the transmission signal ends to send a signal to a transmission control part 9 after the stop period. Then, the transmission control part 9 sends a signal to the transmission signal identifying part 6 and a transmission part 7 to transmit the temporarily stored transmission signal through a transmission part 7. |
