Abstract

PURPOSE:To carry out the multiple communication for a number of circuits and then realize the correction for the code error in an easy way, by delivering the multiple address contents in the time-division way to the transmission control parts which are provided in correspondence to each circuit from the memory at the transmitting device and at the same time delivering the retransmission request signal from the reception side. CONSTITUTION:The same contents to be transmitted to each receiving device 27 is memorized in memory 21 of a fixed size at the transmitting device side, and then delivers in the time-division way the signal to be transmitted to transmission control part 23 provided in correspondence to each circuit from memory 21. On the other hand, device 27 detects the code error and then transmits the retransmission request signal for the signal containing the code error and sent from the ransmission control part of the receiving device. Receiving this retransmission request signal, part 23 within the transmitting device delivers in the time-division way the corresponding signal to part 23 from memory 21 in accordance with the retransmission request signal from devicw 27. In this way, the multiple address communication is carried out for a number of circuits, thus securing the easy correction of the code error.
