2. Description of the Related Art In recent years, it has a function of exchanging data on a local area network, a function of exchanging facsimile data by a facsimile transmission procedure performed over a public network, and sub-address information received by a facsimile transmission procedure. It has an address conversion table that stores a network address such as a mail address corresponding to the sub-address information in association with the sub-address information. The image information received via the public network corresponds to the sub-address information notified from the partner terminal when the image information is received. There has been proposed a network facsimile apparatus for transmitting a network address (mail address) stored in the address conversion table to a destination terminal via a local area network.

When such a network facsimile apparatus is used, image information from a facsimile apparatus connected to a public network can be delivered to a work station apparatus connected to a local area network. It can be greatly expanded, and is very convenient.

[0004]

However, such a conventional apparatus has the following inconveniences.

[0005] That is, the sub-address information for designating the transfer destination is defined in ITU-T Recommendation T. In order to transmit using the protocol signal specified in 30,
The types of characters that can be placed as its contents are limited,
Generally, numbers from “0 to 9” and “*, #, SP
Only codes such as "(space)" can be used.

As described above, since the types of characters that can be used in the subaddress information are considerably limited, it is not possible to directly set a network address as the subaddress information. For this purpose, as described above, the destination terminal side determines the network address of the transfer destination by applying the address conversion table.

For this reason, the originating terminal cannot confirm whether the transfer destination specified by the sub-address information is converted to a desired network address. For example, the sub-address information that does not exist in the destination terminal is incorrectly specified. There is a possibility that the information may not be transferred, and that the terminal may not know that.

The present invention has been made in view of the above circumstances, and has as its object to provide a control method of a network facsimile apparatus in which a destination terminal can confirm a transfer destination.

Now, the network facsimile machine FX
Has an address conversion table that stores sub-address information received by a facsimile transmission procedure and a mail address corresponding to the sub-address information,
The image information received via the public network is transmitted via the local area network LAN to the destination terminal of the mail address stored in the address conversion table corresponding to the sub-address information notified from the terminal at the time of receiving the image information. Send. In the present embodiment, since the image information is distributed using electronic mail, a mail address is used as the network address.

FIG. 3 shows an example of an address conversion table for distributing such facsimile image information.

The address conversion table includes, for each sub-address, a comment for displaying a sub-address, a status indicating a state of update or deletion, a LAN address (mail address), a user name, and the like.
The updated date and time are stored as a set.

Here, each of the mail address and the comment is, for example, a maximum of 64 bytes (octet).
Is limited to

The network facsimile machine FX
Stores an address conversion table for each destination as shown in FIG. 4A for other network facsimile apparatuses to be destinations.

As shown in FIG. 4B, the destination-specific address conversion table includes the destination telephone number, the address conversion table notified from the destination, and the latest one of the address conversion tables stored in the address conversion table. It consists of an update date and time indicating the date and time when the item was saved. The address conversion table includes a sub address, a mail address, and a comment, as shown in FIG.

With the above configuration, the network facsimile machine FX can determine the destination designated when transmitting the image information
When the address conversion table for each destination is not stored, the image information is transmitted according to the procedure shown in FIG. Note that the originating terminal and the terminating terminal in the following description are network facsimile machines FX having the same functions.

First, a call is made from the calling terminal to the called terminal.
When the called terminal responds to the incoming call, a line is established, the called terminal sends out a called station identification signal CED, and then a non-standard function identification signal for notifying the non-standard transmission function provided in the own terminal. An NSF and a digital identification signal DIS for notifying a standard transmission function are transmitted. Here, the non-standard function identification signal NSF also includes an identification code of its own terminal function.

The originating terminal analyzes the contents of the information field of the non-standard identification signal NSF and checks whether the destination terminal has the same function as the terminal itself. When it is confirmed that the destination terminal has the same function as the own terminal, a transmission function to be used at that time is set, a non-standard function setting signal NSS for notifying the set transmission function, and The transmission terminal identification signal TSI for notifying the telephone number is sequentially transmitted. Next, in order to receive the address translation table from the destination terminal, a predetermined signal LSTLAD indicating a transmission request of the address translation table is transmitted.

The destination terminal internally sets the transmission function specified by the received non-standard function setting signal NSS and stores the transmission terminal identification signal TSI. And
At this time, since the signal LSTLAD has been received, one element of the address conversion table stored in the own terminal is selected, and a signal SUBLST including the contents of the element is transmitted to the calling terminal.

FIG. 6A shows an example of the information field of the signal SUBLST.

The signal SUBLST includes "control flag (1 octet)", "sub address (20 octets)", "address length (1 octet)", "LAN address (up to 64 octets)", "comment length (1 octet)". )) And "comment (maximum 64 octets)".

Here, the "control flag" has its bit 0 set to "presence or absence of subsequent data" for indicating whether or not the next signal SUBLST continues, as shown in FIG. , And the bits 1 and 2 are the signals SUBL
"Update status" to indicate whether the subaddress notified in ST has been updated or deleted
Is set to Bits 3 to 7 are undefined.

Upon receiving this signal SUBLST, the calling terminal sends out signal LSTRSP in response.

The signal SUBLST and the signal LSTRSP
Is repeated until all the elements of the destination terminal address translation table are notified.

When the reception of the address conversion table is completed in this way, the calling terminal creates a destination-specific address conversion table for the destination terminal at that time, and displays the list information of the destination-specific address conversion table to the operator. Then, the user is caused to select the subaddress of the intended destination. In this list information, the content of the "comment" is presented as information for interpolating or explaining the content of the mail address, for example, "[mail address] ([comment])".

Next, the calling terminal transmits a signal SUB in which the sub-address information selected by the user is set to the called terminal.

Upon receiving the signal SUB, the destination terminal saves the sub-address included in the signal SUB as a delivery mail address, and issues a signal SUBRSP (OK) for responding that the received sub-address is appropriate. Send to

When receiving the signal SUBRSP (OK) from the receiving terminal, the calling terminal starts a predetermined modem training procedure, and thereafter transmits facsimile image information (FAX message) according to a predetermined group 3 facsimile transmission procedure. .

When the receiving terminal receives the facsimile image information, it accumulates the information, and when the receiving is completed, creates an e-mail in which the sub address of the stored distribution destination is set as the e-mail transmission destination, and transmits the e-mail to the e-mail. Server device SM
And distributes the received facsimile image information to the specified mail address. Note that, as described above, the text of the received facsimile image information converted to MIME information is used as the body of the e-mail in this case.

As described above, if the address conversion table for each destination is not stored for the destination specified by the user, the address conversion table is received from the destination prior to the transmission of the image information, and the list is displayed. Is selected, the sending user can surely specify the mail address of the destination user, thereby suppressing problems such as erroneous delivery.

The network facsimile machine FX
When the destination-specific address conversion table is stored for the destination specified at the time of transmitting the image information, the operation shown in FIG. 7 is performed.

That is, in this case, first, the network facsimile machine FX displays the list information of the address conversion table for each destination of the designated destination to the operator, and allows the operator to select the subaddress of the target destination.

As described above, if a call operation is performed in a state where the sub-address of the destination user is selected, a call is made from the calling terminal to the called terminal. The terminal sends out a called station identification signal CED, and then a non-standard function identification signal NSF for notifying a non-standard transmission function provided in the terminal, and
Digital identification signal D for notifying standard transmission function
Send IS. Here, the non-standard function identification signal NSF also includes an identification code of its own terminal function.

The originating terminal analyzes the contents of the information field of the non-standard identification signal NSF and checks whether the destination terminal has the same function as the terminal itself. When it is confirmed that the destination terminal has the same function as the own terminal, a transmission function to be used at that time is set, a non-standard function setting signal NSS for notifying the set transmission function, and The transmission terminal identification signal TSI for notifying the telephone number is sequentially transmitted. Next, a signal SUB for notifying the sub address information designated by the user and the update date and time stored in the destination address conversion table of the destination is transmitted.

The destination terminal internally sets the transmission function specified by the received non-standard function setting signal NSS, and stores the transmission terminal identification signal TSI.

Then, at this time, since the signal SUB is received next, the address conversion table stored in the terminal is checked for the subaddress notified by the signal SUB, and the update date and time is notified by the signal SUB. Check whether the value is before the updated date and time. When the stored update date and time is a value before the notified update date and time, the notified sub-address can be determined to be appropriate.

In this case, the called terminal has determined that the notified sub-address is appropriate. Therefore, in this case, the destination terminal stores the sub-address as the delivery mail address, and transmits a signal SUBRSP (OK) to the effect that the received sub-address is appropriate to the calling terminal.

When receiving the signal SUBRSP (OK) from the receiving terminal, the calling terminal starts a predetermined modem training procedure, and thereafter transmits facsimile image information (FAX message) according to a predetermined group 3 facsimile transmission procedure. .

When the receiving terminal receives the facsimile image information, it accumulates the information. When the receiving is completed, the receiving terminal creates an e-mail in which the sub address of the stored distribution destination is set as the e-mail transmission destination, and transmits the e-mail to the e-mail. Server device SM
And distributes the received facsimile image information to the specified mail address. Note that, as described above, the text of the received facsimile image information converted to MIME information is used as the body of the e-mail in this case.

Here, on the receiving terminal side, the received signal SUB
As a result of examining the address conversion table stored in the own terminal for the sub-address notified by the above, it is found that the update date and time of the address conversion table is a value after the update date and time notified by the received signal SUB. In this case, the notified sub-address is not always appropriate.

In such a case, as shown in FIG. 8, the destination terminal responds to the signal SUB with a signal SUBRSP indicating that the received subaddress is not appropriate.
(NG) is transmitted to the calling terminal.

The calling terminal receives a signal SUBRSP from the called terminal.
When (NG) is received, a predetermined signal LSTLAD indicating a request for transmitting the address translation table is transmitted in order to receive the address translation table from the destination terminal.

Since the receiving terminal receives the signal LSTLAD, it extracts the elements of the address conversion table in which the update date and time after the update date and time notified by the previously received signal SUB are registered, and stores the update information table in the address conversion table. Then, one element of the update information table is selected, and a signal SUBLST including the content of the element is transmitted to the calling terminal.

Upon receiving this signal SUBLST, the calling terminal sends out signal LSTRSP as a response.

This signal SUBLST and signal LSTRSP
Are repeated until all the elements of the update information table created by the destination terminal are notified.

When the receiving of the address conversion table is completed in this way, the calling terminal creates an address conversion table for each destination for the destination terminal at that time, and displays the list information of the address conversion table for each destination to the operator. Then, the user is caused to select the subaddress of the intended destination.

Next, the calling terminal transmits a signal SUB in which the sub-address information selected by the user is set to the called terminal.

Upon receiving the signal SUB, the destination terminal saves the subaddress included in the signal SUB as a delivery mail address, and issues a signal SUBRSP (OK) for responding that the received subaddress is appropriate. Send to

When receiving the signal SUBRSP (OK) from the receiving terminal, the calling terminal starts a predetermined modem training procedure, and thereafter transmits facsimile image information (FAX message) according to a predetermined group 3 facsimile transmission procedure. .

When the receiving terminal receives the facsimile image information, it accumulates the information. When the receiving is completed, the receiving terminal creates an e-mail in which the sub address of the stored distribution destination is set as the transmission destination of the e-mail, and transmits the e-mail to the e-mail. Server device SM
And distributes the received facsimile image information to the specified mail address. Note that, as described above, the text of the received facsimile image information converted to MIME information is used as the body of the e-mail in this case.

In this way, if the subaddress specified by the calling terminal has been updated, the calling terminal:
Since the address translation table is received again from the receiving terminal,
User can specify the appropriate sub-address,
Problems such as erroneous distribution of image information can be suppressed.

When the selection of the user's subaddress is completed, a signal SUB for notifying the designated subaddress and the update date and time is sent (process 127), and a response signal SUBRSP corresponding to the signal is received (process 128).
Here, in this case, since the sub-address and the update date and time based on the updated destination-specific address conversion table are notified, the signal SUBRSP returned from the destination terminal is:
This is a positive response.

Then, the process proceeds to a step 113, wherein a predetermined image information transmitting operation is executed.

On the other hand, as a result of examining the procedure signal received from the destination terminal, it is determined that the destination terminal does not have the same function. If the result of determination 108 is NO, an appropriate image information distribution operation is performed. It cannot be executed by the receiving terminal.

Therefore, in this case, in order to terminate the communication, a disconnection command signal DCN is transmitted (process 130), and the line is restored (process 131). Then, an error report notifying that the image information distribution operation cannot be performed at the destination terminal is created (process 132), and the error report is generated by the plotter 6.
The record is output (process 133), and the destination-specific address conversion table of the destination designated at that time is deleted (process 1).

If the destination address conversion table of the destination specified by the user is not stored, the judgment 1
When the result of step 03 is NO, a call is made to the designated destination (step 140) and the called station identification signal CED, the non-standard function identification signal NSF and the digital identification signal DIS are received (step 141).

Next, the transmission function to be used at that time is set (process 142), and a non-standard function setting signal NSS for notifying the set transmission function and a transmission for notifying the telephone number of the own terminal are set. The terminal identification signal TSI is sequentially transmitted (process 143).

Here, it is checked whether or not the destination terminal has the same function (decision 144). If the destination terminal does not have the same function, and if the result of the determination 144 is NO, a normal group 3 facsimile is performed. Transmission processing (processing 14
By performing 5), the image information is transmitted.

If the destination terminal has the same function and the result of determination 144 is YES, a predetermined signal LST indicating a transmission request of the address conversion table is set.

Next, the list information of the created address conversion table for each destination is displayed to the operator, the sub address of the target address is selected (process 151), and the signal SUB for notifying the selected sub address and the update date and time is displayed. (Process 152), and the corresponding response signal SUBR
The SP is received (process 153). Here, in this case, since the sub address and the update date and time based on the newly created destination address conversion table are notified, the signal SUBRSP returned from the destination terminal is an affirmative response.

Then, the process proceeds to a step 113, wherein a predetermined image information transmitting operation is executed.

FIG. 13, FIG. 14, and FIG. 15 show an example of processing when the network facsimile machine FX receives an incoming call.

When an incoming call is detected, an incoming call is answered (process 20).

"1" (subsequent data is present) is set to bit 0 of the control flag of ST (process 208), and the signal SUBLS is output.
T is transmitted to the calling terminal (process 209).

The signal L, which is a response signal from the calling terminal,
Upon receiving the STRSP (process 210), the process returns to process 205, and the same process is performed for the remaining elements of the address translation table.

In the case where signal SUBLST is generated for the last data of the address conversion table and the result of determination 207 is YES, signal SUBLST to be transmitted is transmitted.
Is set to "0" (no subsequent data) in bit 0 of the control flag (process 211), and the signal SUBLST is transmitted to the calling terminal (process 212).

The signal L, which is a response signal from the calling terminal,
Upon receiving the STRSP (process 213), subsequently, receives and stores the signal SUB from the calling terminal (process 215), and sends the signal SUBRSP, which is an acknowledgment signal, to the calling terminal (process 216).

Next, a predetermined modem training procedure is executed, the modem speed of the group 3 facsimile modem 10 to be used at that time is determined (process 217), and image information is received and stored by a predetermined image information receiving procedure. (Process 2
18) When the image information reception is completed, a predetermined post-transmission procedure is executed (step 219), and the line is restored (step 22).
0).

Then, with respect to the subaddress included in the signal SUB received at that time, the received image information is distributed to the LAN address registered in the address conversion table by using an electronic mail (process 221).

On the other hand, when the signal LSTLAD is not included in the command signal received in the process 203 and the result of the judgment 204 is NO, the signal S
With respect to the sub-address notified by the UB, the update date and time are extracted from the address conversion table, and the update date and time are
It is checked whether the value is before the update date and time notified by the signal SUB (process 224).

When the stored update date and time is a value before the update date and time notified by signal SUB (decision 225)
Is YES), since the notified sub-address is appropriate, the process shifts to step 216 to output the signal SUBRSP.
Is transmitted, an image information receiving operation is performed, and a distribution operation of the received image information is performed.

Further, when the stored update date and time is the signal SU
If the value is not a value before the update date and time notified in B (the result of determination 225 is NO), the notified sub-address is not necessarily appropriate.

Therefore, in this case, a signal SUBRSP (NG), which is a negative acknowledgment signal, is sent to the calling terminal (not shown). As a result, since the calling terminal transmits the signal LSTLAD, when the signal LSTLAD is received (not shown), the address conversion in which the update date and time after the update date and time notified by the previously received signal SUB are registered. Extract the table elements and create an update information table (Process 2

Next, it is checked whether or not the element selected at that time is the final data (decision 229).
When the result of No. 9 is NO, the signal to be transmitted SUBL
"1" (subsequent data is present) is set to bit 0 of the control flag of ST (step 230), and the signal SUBLS is set.
T is transmitted to the calling terminal (process 231).

The signal L, which is a response signal from the calling terminal,
When the STRSP is received (process 232), the process returns to process 227, and the same process is executed for the remaining elements of the update information table.

When signal SUBLAST is created for the last data of the update information table and the result of determination 229 is YES, "0" (no subsequent data) is set to bit 0 of the control flag of signal SUBLAST to be transmitted. (Process 233), and sends the signal SUBLST to the calling terminal (Process 234).

The signal L, which is a response signal from the calling terminal,
When the STRSP is received (process 235), the process proceeds to process 215, and the subsequent processes are executed to perform the image information receiving operation and perform the distribution operation of the received image information.

In the above-described embodiment, the receiver checks the error of the subaddress for the signal SUB specified by the transmitter.
The sub-address specified in B is appropriate, but if there are other sub-addresses updated after the notified update date and time, for example, when the updated sub-address is specified at the next communication, The communication operation of the address conversion table is always performed.

Thus, when it is known that the communication operation of the address conversion table is to be surely performed later, the communication of the address conversion table is performed during a time period when the communication fee is low, such as at night. By performing the operation, the communication time during actual image information communication can be reduced, and the communication cost can be reduced.

The updated list information of the address conversion table for each destination is displayed to the operator, and the sub address of the target address is selected (step 326).

When the selection of the sub address by the user is completed, a signal SUB for notifying the designated sub address and the update date and time is transmitted (process 327), and a response signal SUBRSP corresponding thereto is received (process 328).
Here, in this case, since the sub-address and the update date and time based on the updated destination-specific address conversion table are notified, the signal SUBRSP returned from the destination terminal is:
This is a positive response.

Then, the process proceeds to a step 315, where a predetermined image information transmitting operation is executed.

On the other hand, as a result of examining the procedure signal received from the destination terminal, it is determined that the destination terminal does not have the same function. If the result of determination 308 is NO, an appropriate image information distribution operation is performed. It cannot be executed by the receiving terminal.

Therefore, in this case, in order to terminate the communication, a disconnection command signal DCN is transmitted (process 330), and the line is restored (process 331). Then, an error report for notifying that the image information distribution operation cannot be performed at the destination terminal is created (step 332), and the error report is plotted by the plotter 6.

A transmission function for transmitting image information according to procedures is provided.

The address conversion table server D
D is for collectively managing the destination-specific address conversion table stored in the network facsimile machine FX in the above-described embodiment. Therefore, in this embodiment, the network facsimile apparatuses FX1 to FX
m stores the address conversion table of the terminal itself, but does not store the destination address conversion table.

In this embodiment, the network facsimile machines FX1 to FXm send the address translation table server device DD to the address translation table server device DD in order to receive the destination address translation table specified by the user at the time of transmission. Requests reception of the destination-specific address translation table of the specified destination.

On the other hand, if the address conversion table server device DD stores the destination-specific address conversion table of the designated destination, the address conversion table server device DD stores the contents of the destination-specific address conversion table in the network facsimile machine FX1 which has requested reception. To FXm, and when the destination address conversion table of the designated destination is not stored, the fact is notified to the network facsimile apparatuses FX1 to FXm that have requested reception.

Then, the network facsimile apparatus F
X1 to FXm are address translation table server devices DD
When the destination address translation table is received from
The contents of the received address conversion table for each destination are displayed in a list, and after the user selects a sub address of the destination, a call is made to the specified destination, and image information is transmitted with the sub address specified. .

When the address translation table server device DD notifies that the destination address translation table of the designated destination is not stored, a call is made to the designated destination and the address translation table is received. The contents of the received address conversion table are displayed in a list, and after the user selects the sub-address of the destination, the sub-address is specified and the image information is transmitted.

Then, in this case, the contents of the received address conversion table are transmitted to the address conversion table server device DD together with the destination information.

The address conversion table server D

The contents of the conversion table are updated, the contents of the updated address conversion table for each destination are displayed in a list, and after the user is allowed to select a sub address of the destination, the sub address is designated and image information is transmitted.

In this case, the contents of the updated address conversion table for each destination are transmitted to the address conversion table server device DD.

As a result, when the address conversion table server device DD receives the updated contents of the address conversion table for each destination from any of the network facsimile machines FX1 to FXm, the address conversion table server device DD stores the stored contents for each of the destinations. Update the address translation table.

In this way, by managing the address conversion tables for each destination collectively by the address conversion table server apparatus DD, there is no need to store the address conversion tables for each destination in each of the network facsimile apparatuses FX1 to FXm. The use efficiency of the entire resources can be improved.

Since all the network facsimile apparatuses FX1 to FXm use the address conversion table for each destination stored in the address conversion table server apparatus DD, which network facsimile apparatus FX1 to FXm is used.
Even when m is used, the same transmission operation can be expected, which is convenient for system operation.

Here, communication of exchange of the address conversion table for each destination between the address conversion table server apparatus DD and the network facsimile apparatuses FX1 to FXm is performed by using an appropriate point-to-point data communication means. Can be.
