DATA TRANSFERRING SYSTEM ABSTRACT OF THE DISCLOSURE Herein disclosed is a data transferring system which provides a plurality of devices using a common bus, said devices send out a requesting signal to a requesting signal line for requesting a transfer of data, and in said devices a priority order is assigned to the transference of the data; and said system further provides a common control unit to said plurality of devices so as to control said bus, said control unit receives said request signal on said requesting signal line and then sends an acknowledging signal for said transfer of data, wherein each of said plurality of devices receives said acknowledging signal so that the device which sends out said requesting signal carries out the transfer of data. According to the present invention, at least one of said plurality of devices, except for the device having the highest priority order, comprises a detecting circuit for detecting said requesting signal on said requesting signal line, wherein said device providing said detecting circuit detects said requesting signal so that said device providing said detecting circuit prevents the sending out of said requesting signal from its own device; and at least one of said plurality of said devices, except for the device having said detecting circuit, is placed on the opposite side of said unit with respect to said device having said detecting circuit. - 1 -
