PROBLEM TO BE SOLVED: To reduce the processing time required for the transmission of corresponding data, after receiving a transmission request. SOLUTION: A receiver 2 repeats transmission of a transmission request R for n-times every prescribed time. A transmission request analysis section 11 of a transmitter 11 receives a transmission request R and analyzes it and outputs an analysis result RE and a transmission enable signal EN. Upon the receipt of the enable signal EN, a transmission register 15 transmits stored data to the receiver 2. A buffer read address counter 13 reads data D, corresponding to the next transmission request R from the buffer 12. An error check section 14 checks an error of the data D read from the buffer 12 and stores the data D in the transmission register 15.
