PURPOSE:To increase remarkably error detection capability in a transfer data by providing a comparator comparing a storage data sent from an equipment at the data transmission side with a stored data calculated by a reception side to an equipment at the data reception side. CONSTITUTION:A transfer data is sectioned at each n-bit by data registers 1 and 4 at the transmission side and the reception side, the stored old data are subject to exclusive OR by exclusive OR units 2, 5, the operated output at the transmission side is inputted to a storage data comparator 7 of a data reception side equipment 12 via a storage data parallel data bus 9 being a parth provided separately and compared with the output of the exclusive OR unit 5 at the reception side. Thus, the data transfer error detecting capability via a parallel data through which the transfer data is transferred from the data transmission side equipment 11 to the data reception side equipment 12 is increased remarkably.
