In a data transfer apparatus 10 , first, second, third data transmitters 141, 142, 143 are located in a data transmission device 11 . Data which must not be influenced by delay of transmission timing of the other data are stored in first, second, third data transmitters 141, 142, 143 . The data selector 16 selects these at a predetermined order or frequency to be transmitted to a data reception device 12 . As a result, when an uncorrectable trouble is detected by a trouble detecting section 27 , a re-issue instruction 21 is issued at a predetermined timing based on information stored in an information round robin section 36 . The corresponding data from the corresponding data transmitter 141, 142 , or 143 is selected by the data selector 16 and then re-sent.
