A data transfer system includes a transmitting device and a receiving device. The transmitting device includes a selecting unit selecting a data body to be transmitted, a transmitting unit dividing the data body and sending the data body to the plurality of signal lines, an alternative-signal-line transmitting unit sending the control data to an alternative signal line, and a signal-line selecting unit connecting the alternative signal line to an output terminal of the transmitting unit or an output terminal of the alternative signal line transmitting unit. When one of the signal lines fails, the transmission selecting unit connects the alternative signal line to the output terminal of the transmitting unit. The receiving device includes reception signal-line selecting units, each reception signal-line selecting unit selects a corresponding signal line and the alternative signal line, the receiving unit assembling the divided data body, and an alternative-signal-line receiving unit receiving the control data.
