Abstract: A facsimile machine including an automatic dialer requiring no dial operation when calling up a specific addressee particularly an addressee requiring frequent communication, allows simplified transmission of the addressee's dial signal to the service line by using "one-touch" key operation, thus achieving an extremely simplified procedure for transmitting written messages therethrough. The automatic dialer is provided with a memory storing dial data of such a specific addressee requiring frequent communications. In response to the operation of a specific instruction key on the operation panel, the automatic dialer reads dial data from memory before delivery to the dial pulse generator circuit, which then outputs the dial pulses to the service line to activate transmission of a message through a telecopier such as a facsimile.
