Abstract

PURPOSE:To transmit a signal accurately without any influence of noise by setting power supply time and signal transmission time alternately on time-division basis and by repeating power supply and signal transmission at constant intervals of time. CONSTITUTION:When a power supply switch 4 is closed by a high-potential pulse from the reception control part 6 of a reception part 1, a power voltage VCC is applied to the charged power source part 14 of a transmission part 2 through a transmission line 12, and the part 14 is charged for a power supply time T1 and discharged for the next signal transmission time T2 to generate a constant voltage VDD, thereby supplying a signal to each part of the transmission part 2. A timing detector 13, on the othe hand, detects the received voltage to send a pulse signal to a transmission control part 16. Then, the control part 16 opens a transmission switch 18 in the time T1 when the received pulse has a low level or closes the switch 18 in the time T1 when the pulse has a high level, thereby sending a transmitted signal to the transmission line 12. Simultaneously, the switch 4 of the reception part 1 is opened and a telegraph switch 11 is closed to receive the transmitted signal.
