PROBLEM TO BE SOLVED: To suppress the deterioration of band utilizing efficiency at the time of generating erroneous transmission information of a data transmitting instruction in a completion control system avoiding confliction by unitarily controlling plural data transmission. SOLUTION: In response to a data transmitting request, a data transmitting instruction transmitting means 9 in a data receiver 2 continually sends data transmitting instruction to a data transmitter 1. A data transmitting instruction reception control means 13 receives first valid one among data transmitting instructions continually sent to the means and transfers it to a received data transmission control means 5 and a data transmission means 6 starts data transmission in response to this. A data transmission monitor means 11 in the data receiver 2 monitors the state of transmission and when data is transmitted corresponding to the data transmitting instruction, detects this to inform a data transmitting instruction transmission control means 12, which finishes the information of data transmitting instruction in response to this. |
