Facsimile transmission/reception method and apparatus using a common bus

摘要

The invention disclosed relates to a facsimile transmission/reception method and apparatus using a common bus in an office automation system, and in detail to a facsimile transmission/reception method and apparatus using a single common bus for transmitting and receiving data and control signals to be interfaced with the outer devices. The apparatus comprises a decoding means 31 being applied with a scanning output data chip selection signal CS1 and a liquid crystal display chip selection signal CS2 for decoding a corresponding selection output signal, a selection output means 34,35 controlled by a first and second storage means 32 and 33 latching data, control signals and the like and the decoding means for selectively outputting the data latched by the first and the second storage means, and a common bus 37 for transmitting the data outputted by the selection output means to the operation panel unit 40. Accordingly, use of a common bus for the data, control signals or the like applied from the external devices will reduce the number of signal lines, enhancing capability of miniaturization of the equipment and adoption of measures against radiative interferences.
