Facsimile image data received from a normal facsimile apparatus connected
to a general telephone network can be transmitted as an e-mail to the
e-mail address of a computer network such as a LAN or the like designated
by the source facsimile apparatus. An apparatus has a LAN I/F (6-14) for
connecting to the LAN, and a line I/F (6-6) for connecting to the public
telephone network. Upon reception of a remote instruction from the public
telephone network, a CPU (6-3) converts received facsimile image data
into e-mail data, and transmits the converted e-mail data to the e-mail
address designated by the received remote instruction.
