At 862, the image signal is transmitted.

Since the operator can set the transmission speed arbitrarily, statistically speaking, the telephone line is often in poor condition, and if there are many cases where fall packs are performed, it is possible to set the transmission speed to low speed mode in advance. The problem of uncertainty can be solved, and the time required for pre-transmission procedures can be shortened by setting the transmission rate in advance.

It is also possible to program the apσ17 to check whether the dial numeric code input from the numeric keypad of the facsimile machine is a registered dial numeric code. Even in the case of input, the above-mentioned communication control can be performed using the registration information corresponding to the dial numeric code.

Further, if a calling operation is performed and the other party's telephone is busy, the calling operation is performed again after one minute, but it is also possible to configure this waiting time so that the operator can arbitrarily set this waiting time.

Furthermore, in addition to the registration information described in this embodiment, by registering various information such as the selection of whether or not to add communication management information and transmit, it is possible to perform control according to the information. can.

〔effect〕

As explained above, according to the original 'MK-, the operator can arbitrarily set the mode according to the communication destination, and it is possible to shorten the communication time by setting the mode in advance. This provides an excellent effect in that it is possible to provide an image communication device that controls communication mode settings.
