る。FIG. 1 is a flowchart showing an embodiment of the retransmission algorithm according to the present invention. The facsimile machine that performs the operation of the algorithm of this embodiment is provided with a telephone number and a
Is the call retransmitted after being disconnected due to a communication error? A table in which a plurality of pairs of retransmission intervals, which are the time until the start of retransmission, are input is stored in a non-displayable memory section. In this embodiment, this will be referred to as a retransmission interval table.

Step 2 shows the operation of transmitting a document using the T, 30 binary procedure of CC engineering TT @ notification, and the transmission is completed normally after a call is made, or the other party is busy or a line abnormality is detected as a no-response timeout. What is the state of the call until it is disconnected or restored due to a communication error? include. Step 3 is a communication abnormality determination step in which it is determined whether the document transmission 2 has ended normally or abnormally. If the original is successfully sent in step 2, step 3
The entire procedure ends with the transmission in step 4. If the document is not delivered due to a communication error in step 2, step 3
The entire Intermediate 1 procedure moves to Step 5.

る。In step 6, the retransmission interval table stored in memory is accessed to search for the destination telephone number of this transmission. If there is a destination phone number in the retransmission interval table in step 7, the process waits for the retransmission interval time stored as a pair with the phone number in step 8, and then resends in step 2? Start. In step 7, if there is no destination telephone number in the retransmission interval table, the process waits for one minute in step 9, and then retransmits in step 2. In addition, steps 6.7.8 and 9 determine how long it takes to resend depending on the destination phone number. Is this a procedure for deciding, and is this example an example using a table? This is what is shown. Instead of using this table, the retransmission interval can also be changed by branching to a step of waiting for a specific retransmission interval for all specific telephone numbers.
