Following the SUB signal, the telephone number (one or more) of the relay distribution destination is stored in the SUB signal, and transmitted from the relay requesting machine to the relay machine. FIG. 6 is a flowchart showing the relay request processing executed by the main control unit 1 of the facsimile machine 20 of the relay request machine 30 of FIG. In FIG. 6, first, in step S1, the telephone number of the repeater
, And the group number is input using the operation unit 5 in step S2. Next, in step S3, it is determined whether input of all designated groups has been completed or whether a specific group "9" has been input.
In the case of ES, the process proceeds to step S4, while in the case of NO, the process returns to step S2 for further input. Step S4
It is determined whether or not the group "9" has been input in step. If YES, the process proceeds to step S5, while if NO, the process proceeds to step S7. Next, in step S5, the telephone number of the relay distribution destination is input using the operation unit 5, and it is determined in step S6 whether the input of all relay distribution destinations has been completed. If YES, the process proceeds to step S7. If NO, step S for further input
Return to 5. Then, in step S7, the repeater 20
, And the NS from the repeater 20 in step S8
F and DIS signals are detected, and the NSS
The relay instruction bit and the group number of the relay instruction data are inserted into the FIF of the signal and transmitted. Then, step S10
It is determined whether or not the group "9" has been designated by the NSS signal in step. If YES, the process proceeds to step S11, and if NO, the process proceeds to step S12. Step S1
At step 1, the telephone number of the relay distribution destination is inserted into the FIF of the SUB signal and transmitted. In step S12, the DCS signal is transmitted. Further, after transmitting the image data for relay distribution in step S13, the line is opened in step S14, and the relay request processing ends. FIGS. 7 and 8 are flowcharts showing the relay processing executed by the main control unit 1 of the facsimile machine 20 of the repeater 20 of FIG. In FIG. 7, first,
In step S21, it is determined whether or not a call is received. When the call is received, an NSF and a DIS signal are sent out in step S22, and the SUB address receiving capability bit is turned on. Next, in step S23, NS
The S, SUB, and DCS signals are detected, and it is determined in step S24 whether or not the NSS signal has relay instruction data.
On the other hand, if NO, the flow advances to step S25 because it is not a relay instruction. After receiving the image data in step S25 and printing it using the image recording unit 3, the line is opened in step S26, and the relay processing ends. On the other hand, in step S27, the NSS signal
It is determined whether or not there is a group “9”. If YES, the process proceeds to step S28, and if NO, the process proceeds to step S29. In step S28, F of the SUB signal
After detecting the telephone number of the IF, receiving the image data in step S29 and storing it in the image memory 8, the line is opened in step S30, and the process proceeds to step S31 in FIG. In step S31 of FIG. 8, all the group numbers in the FIF of the NSS signal are detected, and in step S32, the telephone number of the relay destination corresponding to the group number is stored in the transmission queue memory 7b. However, when only the group “9” is designated, no telephone number is stored. Then, in step S33, it is determined whether the processing has been completed for all the specified groups, and YES
If it is, the process proceeds to step S34, while if it is NO, the process returns to step S33. In step S34, it is determined whether or not the group “9” is designated. If YES, the process proceeds to step S35, while if NO, the process proceeds to step S3.
Proceed to 6. In step S35, the IF of the SUB signal
And stores it in the transmission queue memory 7b.
In step S36, a call is made to the telephone number of the relay distribution source in the transmission queue memory 7b, and the image data in the image memory 8 is transmitted in step S37. Then, in step S38, it is determined whether or not the transmission processing has been completed for all relay distribution destinations. If YES, the process proceeds to step S39, whereas if NO, the process returns to step S37. Further, in step S39, the received image data is printed using the image recording unit 3 and output, and in step S40, the image memory 8 is released, and the relay processing ends. As described above, according to the present embodiment, the main control unit 1 of the repeater, when a specific group (for example, group number: G9) is designated by the group designation signal (see FIG. (YES in step S27 of FIG. 7 and step S34 of FIG. 8) The image data is transmitted to the telephone number of the distribution destination transmitted from the relay requesting machine using the SUB signal (step S28 of FIG. 7, step S35 of FIG. 8).
And S36). Therefore, based on the relay distribution instruction from the relay requester using the conventional group number and the instruction on the relay distribution destination by the direct telephone number, the relay broadcast of the image data can be performed. The image data for relay distribution can be transmitted to relay distribution destinations other than the relay distribution destinations of the group stored in advance, and this has a unique effect that the distribution destination can be flexibly designated from the relay requesting machine. If a plurality of group designations are made by the group designation signal and a specific group designation is included, the main control unit 1 of the repeater transmits the telephone number of the distribution destination stored in the relay destination table 7a and the The image data is transmitted from the relay requesting machine to the telephone number of the distribution destination specified (steps S31, S32, S35, S36 in FIG. 8).
Therefore, since the same image data for relay distribution can be transmitted to both the conventional group number and the relay distribution destination that directly specifies a telephone number, a temporary relay distribution destination is added to the group for each communication. Thus, the operability of the relay broadcast function can be improved. Further, the main control unit 1 of the relay requesting machine sends the group designation signal for designating the group of the relay delivery destination, information of another relay delivery destination, and the image data for relay delivery to the facsimile machine of the relay machine. (Steps S9-S13 in FIG. 6). Therefore, based on the relay distribution instruction from the relay requester using the conventional group number and the instruction on the relay distribution destination by the direct telephone number, the relay broadcast of the image data can be performed. The image data for relay distribution can be transmitted to relay distribution destinations other than the relay distribution destinations of the group stored in advance, and this has a unique effect that the distribution destination can be flexibly designated from the relay requesting machine. <Modification> In the above embodiment, the example of the facsimile apparatus 20 has been described. However, the present invention is not limited to this, and is connected to a public network such as a public telephone network or a public digital network. For example, the present invention can be applied to a communication terminal device including a data communication device. [0030] [0031] As has been described in the foregoing, according to the communication terminal apparatus according to the present invention, a group designation signal from the relay request machine
