置。[Claims for Utility Model Registration] In a data transfer device that transfers data between two or more communication devices connected via a data bus, the data bus is an address data bus that transmits and receives addresses and data, and an address data bus that transmits and receives addresses and data. The communication device is configured with a control bus that controls the flow of data, and an error detection line, and in each communication device, errors are detected by comparing each data on the internal bus and the address/data bus, and the error detection signal is sent to the error detection line. Data characterized in that it is provided with a comparison circuit that outputs to the detection line, and a response circuit that inputs the signal from the error detection line and is configured not to respond when the error detection line is asserted. Transfer device.
