SIMULTANEOUS TRANSMISSION CIRCUIT FOR DIFFERENT INFORMATION

PURPOSE:To transmit different information to plural converters etc. at the same time, by providing a circuit distributing parallel information from a processing section to each terminal and a parallel-series conversion circuit buffering the information. CONSTITUTION:Parallel information is applied to a distribution circuit 2 from the processing section 1. A control signal is applied from a control circuit 4 to the circuit 2, which distributes the parallel information to the parallel series conversion circuits 3a-3n sequentially. Since a set pulse is given to the circuits 3a-3n, for example parallel information A1 is set to the circuit 3A and parallel information B1 is set to the 3b. In setting the parallel information N1 to the final circuit 3n, a serial output pulse is applied to the circuits 3a-3n at the same time, the parallel information A1-N1 are converted into serial information and transmitted to the terminal devices at the same time.
