Composite communication apparatus having facsimile transmission unit and electronic mail transmission unit

摘要

A composite communication apparatus of the present invention is provided with a facsimile transmission unit and an electronic mail transmission unit, when the size of an image data attached to an electronic mail is larger than a predetermined reference value, the image data is transmitted by use of the facsimile transmission unit instead of the electronic mail transmission unit. As the result, the data amount fed on a network is reduced and the efficiency reduction of the network system is prevented.
