ABSTRACT:
The invention comprises modulating means for modulating digital data of fax format into analog signal and transmitting, a fax apparatus connected directly to the modulating means without resort to telephone circuit, DC feed means for feeding direct current to the fax apparatus, and call signal generating means for generating and sending out a call signal to the fax apparatus, in which a call signal is sent out from the call signal generating means, and the output of the modulating means is sent out to the fax apparatus without passing through telephone circuit, so that the fax apparatus connected directly to the modulating means can automatically receive data from the modulating means such as modem. As a result, image data such as bit map data can be easily transmitted directly to the fax apparatus and printed out, and the user can use the fax apparatus easily as a handy printer.
