Description

Description: TECHNICAL FIELD The present invention relates to a data communication apparatus, and more particularly to a data communication apparatus having a data relay / broadcast function.

[Conventional example]

Conventionally, this type of device, for example, a facsimile device having a relay broadcast function, receives a relay instruction from the instructing station, accepts it regardless of who the other device is, and relays it to the other party of the broadcast instructing the instructing station. It was broadcasting. Therefore, for example, when the information from a fixed party is transmitted only to a fixed party, such as a telephone network, and when a so-called relay broadcasting network is established, the relay broadcasting of the partner relay instruction station is performed. If there is an error in the previous designation, the relay station accepts it as it is and sends the image signal to the wrong broadcast destination, or it does not send the image signal to the other party who should originally broadcast A phenomenon that sometimes induces confusion in the web, such as a bird, was occasionally seen.
Further, the relay station does not perform the operation of accepting the relay instruction after sufficiently recognizing the other party, and the relay broadcast destination is determined by the instruction of the other party relay instruction station. I was forced to do a relay broadcast that I didn't have to do. When the relay station returns the relay result to the relay instruction station, the transmission station identification signal (TS
Since the other party's telephone number declared in i) was sent as a selection signal as it is, for example, the area code is not added to TSi, and the relay station is the area outside the relay instruction station. When the telephone number of the relay instruction station as seen from the relay station differs from the telephone number declared in the TSi signal of the relay instruction station, the return of the relay result cannot be automatically performed. In addition, when the relay instruction station performs the relay broadcast, all the relay broadcast destination telephone numbers had to be specified and transmitted to the relay station. There is a problem that a complicated key operation is required and a great load is imposed on the operator in terms of time, body and spirit. Further, the data of the telephone number transmitted from the relay instruction station to the relay station is enormous, and the processing performed by the relay instruction station, the relay station, and both facsimile devices is complicated.
There is a drawback that the time and electric energy required for it are enormous.

The relay station first compares the telephone number of the partner transmitter declared in TSi communication in STEP 1 with the lower digits of the relay instruction telephone number registered in the terminal itself (probably the lower 4 digits) and makes them the same. If so, proceed to STEP 6, and if a difference is found, proceed to STEP 2. In STEP2, non-standard device setting signal (NSS
Check the relay instruction bit on (Signal) and if it is not standing, that is, if the other transmitting station does not give the relay instruction, it shifts to normal reception as it is, if it is standing, that is, If the partner transmitting station has given a relay instruction, proceed to STEP 3. In STEP3, check ON / OFF of the relay refusal switch, if it is ON, a relay error will occur, the relay will send DCN to the other party, and if it is OFF,
Go to STEP4. In STEP4, it is investigated whether or not the relay broadcast receiving station is registered in the own machine. If it is not registered, a relay error occurs, and if it is registered, STEP5
Go to. In STEP5, delete the telephone number of the partner transmitter declared in the TSi signal and the numbers other than 0-9 of the relay permission telephone number registered in the own machine and compare the remaining 4 digits of the remaining numbers. If they match, the process moves to relay reception, otherwise a relay error occurs. Explaining the case where the process proceeds to STEP6, SETP6 first determines whether or not the network is connected to NTT's fax network (F network), and if it is connected to the F network, proceeds to STEP8 and connects. If not, proceed to STEP 7. In STEP 7, the telephone number network reception SW registered in the machine is checked, and if it is ON, proceed to STEP 8, and if it is OFF, proceed to normal reception. In STEP8, ON / OFF of relay refusal SW is investigated and it is turned ON.
In the case of, a relay error occurs, the relay machine sends a disconnection command (DCN) to the other party, and when OFF, proceeds to STEP 9. S
In TEP9, it is investigated whether or not the relay broadcast receiving station is registered in the own device. If it is not registered, a relay error occurs, and if it is registered, relay reception is started.

Next, the operation of relay broadcast will be described based on the operation flow chart of the central control unit 14 in FIG. First, the relay station performs memory reception (relay reception) for the purpose of relay broadcasting (S10). After that, when it ends, the relay station performs broadcast transmission to the broadcast receiving station registered in advance in the relay station (S11). When it ends (S12), the relay result is returned to the telephone number of the relay instruction station registered in the relay station.

FIG. 4 shows the flow of the above signals. Relay broadcast is performed in the flow of 41 relay instructions, 42 relay broadcasts, and 43 relay result returns.

Further, in FIG. 6, the designated station telephone number and the relay refusal SW telephone network reception SW receiving station telephone number stored in the RAM are input, set and deleted by operating the keys shown in FIG. is there.

Next, a description will be given of another embodiment of the above-mentioned embodiment in which the operation of the relay broadcast is partially changed. The difference between the other embodiments and the above-described embodiment is the control operation of the central control unit 14.

FIG. 8 is a diagram for explaining the relay broadcast operation, and FIG. 9 is a diagram for explaining the internal area of the RAM 13.

In the above-mentioned configuration, when the relay station shifts to the relay broadcast operation, it first receives the memory (S14), determines the relay image print SW on the RAM set in its own machine, and if it is ON. , The relay image is printed, and if not, the next operation is performed without printing (S15).
Next, the relay station selects a broadcast receiving party registered in advance in the relay station according to the instructed station telephone number and performs relay broadcast (S17), and when that is completed, then the relay result return operation is performed. (S18). Here, the relay station determines the information stored in the relay result return refusal SW100 area of the RAM 13 set in itself (S19), and if the relay result return refusal SW is on, prints the relay result (S22 ), Then the end, and then OFF
If so, the operation proceeds to the relay result return operation, and the relay result is returned to the relay result return destination registered in advance in the relay station according to the instruction station telephone number (S20). After that, the information of the relay result print SW98 of the RAM13 set in the own machine is determined (S21)
Then, the operation is ended without printing the relay result.

As described above, according to the flow chart of FIG. 7, for example, the operation settings of the relay station are (1) the receiving stations for the instruction station A are D and E, and the relay result return destination is H. , (2)
The receiving station for the instruction station B is E, G and the relay result return destination is H. (3) The receiving station for the instruction station C is F, G
If the relay result return address is H, (4) print the relay result image and print the relay result, and (5) do not refuse the relay result return, the instructing station, A, B, C
When there is a relay instruction and image signal transmission, the flow of the image signal becomes as shown in FIG. 8, and all the relay results are transmitted to the management station H, and the relay station prints the relayed image and the relay result. Done.

As described above, according to the present embodiment, a relay station from a malicious or erroneous relay instruction station by preventing the relay station from accepting relay instructions other than the relay of the preregistered instruction station, At the same time, avoiding a relay instruction that may adversely affect other instruction stations and receiving stations that form the relay broadcast network, and simplifying the instruction at the relay instruction station by registering the broadcast receiving station in advance at the relay station Probability of relay broadcasting network that has been determined to be changed, comparison between the designated station telephone number registered in the relay station and the designated station telephone number declared by the TSi signal on the side of the designated station other than 0-9 Numbers such as “()” and “-” are deleted, and then avoided by avoiding erroneous comparison. Declaration is made by the designated station telephone number registered in the relay station and the designated station side TSi signal. Comparing with the instruction station telephone number By performing comparison, for example, avoiding erroneous comparison due to area code, etc., and returning the relay result to the designated station telephone number registered in the relay station to determine whether the other party is a local station. Protecting the relay station against unilateral relay instructions from the relay instruction station by returning the relay result to the reliable reference station telephone number that distinguishes whether it is a station, etc. The relay station operator determines whether or not the relay image is printed, so that the required relay result can be secured, unnecessary relay result can be removed, and the relay result can be returned to other than the instructing station. For example, it became possible to set up a management station that manages one or more relay broadcasting networks.

By making it possible for the relay station to refuse the return of relay results, it is possible to reduce the amount of telephone line usage and to eliminate communication costs, for example, in response to a relay instruction from overseas. It has become possible.

By selecting a pre-registered broadcast receiving station destination according to the designated station telephone number and performing relay broadcast, for example, the relay station is located as a relay station of multiple facsimile relay networks and relay broadcast is performed. It became possible to do.

By deciding whether or not to print the relay result at the relay station, it becomes possible to print only the required result at the discretion of the relay station, which is effective in saving resources.
