PURPOSE:To eliminate single-point distortion by providing the transmitting circuit of a telex station equipment with a counter circuit to count the difference in time between the operation of a mercury relay and its recovery, by correcting the count value into transmitted data, and by operating the mercury relay according to the corrected data. CONSTITUTION:When transmitted data is transmitted via the contact of the mercury relay, it is delayed by operation time ton of the relay and further delayed by recovery time toff. Therefore, time difference td between recovery time toff and the operation time is detected and corrected data is generated by counter circuit C by correcting the transmitted data while paying attention to time difference td to put relay S into operation according to the corrected data, so that the transmitted current waveform may have the same data width (l) with the transmitted data. Thus, single-point distortion can be eliminated. |
