PURPOSE:To realize a highly efficient transfer of information with a high speed of conversion, by changing the signals to be transmitted when the parallel control signals to be transferred are reversed into the series signals through parallel-series conversion. CONSTITUTION:A code inversion time is detected through a control signal inversion detecting circuit 20 and at a transmitter side device for each of parallel input control signals a-c. One of these control signals is applied to a transmission frame producing circuit 21 in the form of a sampling pulse (h), and other control signals are applied to a register 22. At the same time, parallel control signals a-c applied to the register 22 plus data (d) are sampled through the register 22 and with the sampling pulse and then applied to a shift register 23. the circuit 21 delivers a frame for transmission to the register 23 by the sampling pulse. The register 23 changes the sampled input signals a-d into the series signals from the parallel signals by the transmission frame to be transmitted to a transmission line 29 from a transmitting circuit 24 in the form of a series signal (i). |
