  Here, in the present embodiment, basically, data exchange between the local area network LAN and the Internet is performed between a transmission protocol up to a transport layer called TCP / IP and a communication protocol of higher layers. A combination (so-called protocol suite) is applied. For example, in the exchange of e-mail data, a communication protocol called SMTP (Simple Mail Transfer Protocol) is applied as an upper layer communication protocol.

  In addition, with respect to communication protocols such as TCP / IP and SMTP, and the data format and data structure of e-mails, RFCs issued by organizations that compile technical contents related to the Internet called IETF (Internet Engineering Task Force), respectively. (Request For Comments) document. For example, RFC is defined as RFC793, IP as RFC793, SMTP as RFC821, and e-mail format as defined by RFC822, RFC1521, RFC1522 (MIME (Multipurpose Mail Extension) format), respectively.

  Here, the facsimile image information is binary data, and the e-mail cannot include binary data directly. Therefore, a predetermined conversion method (for example, Base64 encoding method) is applied to read the readable information (7-bit information). The character code is included in the email. Such a format of e-mail text information is called MIME format.

  An example of an e-mail used when transmitting image information in this way is shown in FIG.

  This e-mail is an e-mail in a multi-part MIME format having a plurality of body parts. The e-mail transmission date (“Date” field), the destination e-mail address (“To” field), and the source e-mail address (“From” “Field”), a mail header part comprising predetermined information, a text part part for carrying text data, and a binary part part for carrying picture information. In the binary part part, the picture information is MIME-converted. MIME encoded data obtained in this way is arranged.

  The image information carried by e-mail is the original image data compressed by MH encoding and converted into TIFF-F format. Therefore, as MIME encoded data, this TIFF-F data is A MIME converted version is placed.

  Here, in the TIFF-F format, image data of a plurality of pages can be collected as one file, so that data of one transmission image information file consisting of a plurality of pages can be arranged in one binary part portion. .

  When a normal transfer destination is designated, a character string “facsimile reception notification” as shown in FIG. 8 is arranged in the “Subject” field of the mail header, and an emergency destination is designated. In this case, a character string “[Urgent] facsimile reception notification” as shown in FIG. 9 is arranged in the “Subject” field of the mail header portion.

  As a result, the user who received the e-mail can clearly know that the e-mail carries facsimile image information, and can also clearly know that the e-mail is facsimile image information related to emergency communication. .

  In the “From” field of the mail header portion, the contents of the calling number notified from the digital public network ISDN at the time of the incoming call are arranged, whereby the user of the e-mail clearly identifies the source of the received image information. I can know.

  10 to 17 show an example of processing executed by the network facsimile apparatus FX when an incoming call is detected.

  When a call setup message SETUP is received from the digital public network ISDN and an incoming call is detected, it is checked whether or not delivery by called number is set at that time (decision 101). When the result of determination 101 is YES, it is checked whether the received call setting message SETUP includes a called number (determination 102).

  If the received call setting message SETUP does not include the called number, and the result of determination 102 is NO, normal incoming call processing (processing 103) is executed, and the operation when this incoming call is detected is terminated. .

  When the received call setting message SETUP includes the called number and the result of determination 102 is YES, it is checked whether the called call response number is registered in the called call response number table (determination 104). ).

  When the incoming call response number is registered in the incoming call response number table and the result of determination 104 is YES, it is checked whether the incoming call number at that time is registered in the incoming call response number table (determination 105). If the result of determination 105 is NO when the incoming number at that time is not registered in the incoming call response number table, the incoming call at that time is ignored (step 106).

  On the other hand, when the incoming number at that time is registered in the incoming call response number table and the result of determination 105 is YES, and when the incoming call response number is not registered in the incoming call response number table, When the result of determination 104 is NO, it is checked whether or not “forward” or “emergency destination” is registered as an attribute for one or more called numbers (ISDN numbers) registered in the called number distribution table ( Decision 107).

  When the result of determination 107 is NO, the process proceeds to process 103, and a normal incoming call process is executed.

  If the result of determination 107 is YES, the incoming call is answered (process 108), a predetermined group 4 facsimile reception / storage process (process 109) is executed, and a group 4 facsimile transmission operation is performed with the partner terminal. The received image information is stored in the image storage device 9. When the image information receiving operation is finished, the line is released (process 110).

  Next, it is checked whether or not “all destinations” is registered as an attribute for the called number at that time (determination 111). If the result of determination 111 is NO, is “emergency destination” registered as an attribute? A check is made (decision 112).

  When the result of determination 112 is NO, since “transfer” is registered as an attribute for the called number at that time, the corresponding mail address (forwarding mail address) is acquired from the called number distribution table ( Process 115), e-mail header information is created (Process 116), the received image information stored at that time is converted into TIFF format image data (Process 117), and the TIFF format image data is converted to MIME. Then, the binary part data of the body information of the electronic mail is created (process 118), and the electronic mail created as described above is transmitted (process 119).

Emergency contact information can be provided to the user of the network facsimile apparatus FX, and more reliable emergency contact communication can be performed.

  In addition, when “all destinations” are registered as attributes for the called number at that time, and the result of determination 111 is YES, “transfer” is registered as the attribute value from the called number distribution table. The corresponding mail address (forwarding mail address) is acquired from all the items (process 130), the header information of the e-mail is created (process 131), and the received image information stored at that time is converted into a TIFF format image. Data is converted (process 132), and the TIFF image data is MIME converted to create binary part data of the body information of the e-mail (process 133), and the e-mail created as described above is transmitted. (Process 134).

  In this way, when the ISDN number in which “all destinations” is registered as an attribute in the called number distribution table is notified as the called number, all the transfer destinations registered in the called number distribution table are registered. For the mail address, an e-mail carrying the received image information is sent, which is very convenient.

  On the other hand, when the delivery by the called number is not set and the result of determination 101 is NO, the delivery operation by the sub address is performed.

  Therefore, first, it is checked whether or not the received call setting message SETUP includes the called subaddress (decision 140).

  When the received call setting message SETUP does not include the called subaddress, and the result of determination 140 is NO, the process proceeds to processing 103 and normal incoming call processing is executed to perform the operation when this incoming call is detected. finish.

  When the received call setting message SETUP includes the called subaddress and the result of determination 140 is YES, it is checked whether or not the subaddress is registered in the subaddress distribution table (decision 141).

  When the subaddress is registered in the subaddress distribution table and the result of determination 141 is YES, it is checked whether the destination subaddress at that time is registered in the subaddress distribution table (decision 142), and the destination subaddress at that time Is not registered in the sub-address distribution table, and if the result of determination 142 is NO, the process proceeds to process 106, and the incoming call at that time is ignored.

  On the other hand, when the result of determination 142 is YES when the destination subaddress is registered in the subaddress distribution table, and when the subaddress is not registered in the subaddress distribution table, the result of determination 141 is NO. When this happens, it is checked whether “transfer” or “emergency destination” is registered as an attribute for one or more subaddresses registered in the subaddress distribution table (decision 143).

  When the result of determination 143 is NO, the process proceeds to process 103, and normal incoming call processing is executed.

  If the result of determination 143 is YES, an incoming call response is processed (process 144), a predetermined group 4 facsimile reception / storage process (process 145) is executed, and a group 4 facsimile transmission operation is performed with the partner terminal. The received image information is stored in the image storage device 9. When the image information receiving operation is finished, the line is released (process 146).

  Next, it is checked whether or not “all destinations” is registered as an attribute for the destination subaddress at that time (decision 147). If the result of determination 147 is NO, is “emergency destination” registered as an attribute? A check is made (decision 148).

  When the result of determination 148 is NO, since “forward” is registered as an attribute for the destination subaddress at that time, the corresponding mail address (mail address of the transfer destination) is acquired from the subaddress distribution table (processing) 150), creating header information of the e-mail (process 151), converting the received image information accumulated at that time into image data in TIFF format (process 152), converting the image data in TIFF format into MIME, Data of the binary part of the body information of the electronic mail is created (process 153), and the electronic mail created as described above is transmitted (process 154).

  In this way, when the subaddress for which “transfer” is registered as an attribute in the subaddress distribution table is notified as the destination subaddress, the mail address registered in the subaddress (the destination subaddress) is received. An e-mail carrying the selected image information is sent.

  In addition, when “emergency destination” is registered as an attribute for the destination subaddress at that time and the result of determination 148 is YES, the received image information stored in the image storage device 9 is encoded and decoded. The unit 8 decodes the original image data (process 160), transfers the obtained image data to the plotter 6, and records and outputs the received document (process 161).

  Next, the corresponding mail address (emergency destination mail address) is obtained from the sub-address distribution table (process 162), and the above-described emergency e-mail header information is created (process 163) and stored at that time. The received image information is converted to TIFF format image data (process 164), the TIFF format image data is converted to MIME, and binary data of the e-mail is created (process 165). The created electronic mail is transmitted (process 166). At this time, the text part data of the body information of the e-mail can include contents indicating that it is an emergency contact.

  In this way, when the subaddress for which “emergency destination” is registered as an attribute in the subaddress distribution table is notified as the destination subaddress, the original of the received image information at that time is locally recorded and output. At the same time, since an emergency contact e-mail carrying the received image information is transmitted to the mail address registered in the subaddress, the received original is recorded and output in the network facsimile apparatus FX. Emergency contact information can also be provided to FX users, and more reliable emergency contact communication can be performed.

I can know. This notification is applied only when the analog public network PSTN provides a caller ID notification service.

  24 to 31 show an example of processing executed by the network facsimile apparatus FXa when an incoming call is detected.

  When an incoming call is detected from the analog public network PSTN, it is checked whether or not distribution by dial-in number is set at that time (decision 201). If the result of determination 201 is YES, it is checked whether a dial-in number has been received when the incoming call is detected (decision 202).

  If the dial-in number is not received when an incoming call is detected and the result of determination 202 is NO, the normal incoming call process (process 203) is executed, and the operation when this incoming call is detected is terminated.

  If the dial-in number is received when the incoming call is detected and the result of determination 202 is YES, it is checked whether the incoming call response number is registered in the incoming call response number table (determination 204).

  When the incoming call response number is registered in the incoming call response number table and the result of determination 204 is YES, it is checked whether the dial-in number at that time is registered in the incoming call response number table (determination) 205). If the dial-in number at that time is not registered in the incoming call response number table and the result of determination 205 is NO, the incoming call at that time is ignored (step 206), and the incoming call operation is terminated. To do.

  On the other hand, when the dial-in number at that time is registered in the incoming call response number table and the result of determination 205 is YES, and when the incoming call response number is not registered in the incoming call response number table When the result of determination 204 is NO, it is checked whether “forward” or “emergency destination” is registered as an attribute for one or more dial-in numbers registered in the called number distribution table (decision 207). ).

  When the result of determination 207 is NO, the process proceeds to process 203 and normal incoming call processing is executed.

  If the result of determination 207 is YES, an incoming call is answered (process 208), a predetermined group 3 facsimile reception / storage process (process 209) is executed, and a group 3 facsimile transmission operation is performed with the partner terminal. The received image information is stored in the image storage device 39. When the image information receiving operation is finished, the line is released (process 210).

  Next, for the dial-in number at that time, it is checked whether or not “all destinations” is registered as an attribute (decision 211). If the result of determination 211 is NO, “emergency destination” is registered as an attribute. Whether it is present (decision 212).

  When the result of determination 212 is NO, since “forward” is registered as an attribute for the dial-in number at that time, the corresponding mail address (transfer destination mail address) is acquired from the dial-in number distribution table. (Processing 215), creating e-mail header information (Processing 216), converting the received image information stored at that time to TIFF format image data (Processing 217), and converting the TIFF format image data to MIME conversion Then, binary part data of the body information of the electronic mail is created (process 218), and the electronic mail created as described above is transmitted (process 219).

  In this way, when a dial-in number for which “transfer” is registered as an attribute in the dial-in number distribution table is notified as a dial-in number at the time of incoming call, it is registered in the dial-in number. An e-mail carrying the received image information is transmitted to the e-mail address.

  In addition, when “emergency destination” is registered as an attribute for the called number at that time and the result of determination 212 is YES, the received image information stored in the image storage device 39 is encoded and decoded. The original image data is decoded by the unit 8 (process 220), the image data obtained thereby is transferred to the plotter 6, and the received document is recorded and output (process 221).

  Next, a corresponding mail address (emergency destination mail address) is obtained from the dial-in number distribution table (process 222), and the above-described emergency e-mail header information is created (process 223). The received image information stored in the TIFF format is converted to TIFF format image data (process 224), and the TIFF format image data is converted to MIME to create binary part data of the email (process 225). The created e-mail is transmitted (process 226). At this time, the text part data of the body information of the e-mail can include contents indicating that it is an emergency contact.

  In this way, when the dial-in number in which “emergency destination” is registered as an attribute in the dial-in number distribution table is notified as the dial-in number at the time of incoming call, the received image information at that time An original is recorded and output locally, and an emergency contact e-mail carrying the received image information is transmitted to the mail address registered in the dial-in number. Is recorded and output, it is possible to provide emergency contact information to the user of the network facsimile apparatus FXa and to perform more reliable emergency contact communication.

  In addition, when “all destinations” is registered as an attribute for the called number at that time, and the result of determination 211 is YES, “transfer” is registered as the attribute value from the dial-in number distribution table. The corresponding mail address (forwarding destination mail address) is acquired from all the items (process 230), the header information of the e-mail is created (process 231), and the received image information stored at that time is stored in the TIFF format. The image data is converted into image data (process 232), the TIFF format image data is converted into MIME, and binary part data of the body information of the e-mail is generated (process 233). Transmit (process 234).

  In this way, when a dial-in number having “all destinations” registered as an attribute in the dial-in number distribution table is notified as a dial-in number at the time of incoming call, it is registered in the dial-in number distribution table. This is very convenient because an e-mail carrying the received image information is transmitted for all e-mail addresses of the transfer destinations.

  On the other hand, when the distribution by the dial-in number is not set and the result of determination 201 is NO, the distribution operation by the subaddress notified by the signal SUB received in the group 3 facsimile transmission procedure is performed.

  Accordingly, first, an incoming call response is processed (process 240), a predetermined group 3 facsimile reception and storage process (process 241) is executed, a group 3 facsimile transmission operation is performed with the partner terminal, and the received image information is stored as an image. Accumulate in device 39. When the image information receiving operation is finished, the line is released (process 242).

  Then, it is checked whether or not the signal SUB is received in the group 3 facsimile transmission procedure at that time (decision 243). If the signal SUB is received in the group 3 facsimile transmission procedure, the result of judgment 243 is YES. If so, it is checked whether or not the sub address is registered in the sub address distribution table (decision 244).

  If the subaddress is registered in the subaddress distribution table and the result of determination 244 is YES, it is checked whether the subaddress notified at that time is registered in the subaddress distribution table (decision 245). If the subaddress notified at that time is not registered in the subaddress distribution table and the result of determination 245 is NO, the processing at the time of the incoming call is terminated at that point. Therefore, in this case, the received image information is not output anywhere.

  On the other hand, if the destination subaddress at that time is registered in the subaddress distribution table and the result of determination 245 is YES, and if the subaddress is not registered in the subaddress distribution table, the result of determination 244 is NO. If so, it is checked whether “transfer” or “emergency destination” is registered as an attribute for one or more subaddresses registered in the subaddress distribution table (decision 246).

  When the result of determination 246 is NO and when the result of determination 243 is NO, the received image information accumulated in the encoding / decoding unit 28 is decoded into the original image data, and is recorded and output from the plotter 36. (Process 247), the process at the time of the incoming call is terminated.

  When the result of determination 246 is YES, it is checked whether or not “all destinations” is registered as an attribute for the subaddress at that time (determination 248). When the result of determination 248 is NO, the attribute is “emergency” It is checked whether “destination” is registered (decision 249).

  When the result of the determination 249 is NO, since “transfer” is registered as an attribute for the subaddress at that time, the corresponding mail address (mail address of the transfer destination) is acquired from the subaddress distribution table (process 250). ), The header information of the e-mail is created (process 251), the received image information stored at that time is converted into TIFF format image data (process 252), the TIFF format image data is converted to MIME, Data of the binary part of the mail body information is created (process 253), and the electronic mail created as described above is transmitted (process 254).

  In this way, when the subaddress for which “transfer” is registered as an attribute in the subaddress distribution table is notified as the destination subaddress, the mail address registered in the subaddress (the destination subaddress) is received. An e-mail carrying the selected image information is sent.

  Further, when “emergency destination” is registered as an attribute for the destination subaddress at that time, and the result of determination 249 is YES, the received image information stored in the image storage device 39 is encoded and decoded. The original image data is decoded by the unit 8 (process 260), and the obtained image data is transferred to the plotter 6 to record and output the received document (process 261).

  Next, the corresponding mail address (emergency destination mail address) is acquired from the sub-address distribution table (process 262), and the above-described emergency e-mail header information is created (process 263) and stored at that time. The received image information is converted into TIFF format image data (process 264), and the TIFF format image data is MIME converted to create binary part data of the email (process 265), as described above. The created electronic mail is transmitted (process 266). At this time, the text part data of the body information of the e-mail can include contents indicating that it is an emergency contact.

  In this way, when the subaddress in which “emergency destination” is registered as an attribute in the subaddress distribution table is notified as the subaddress, the original of the received image information at that time is recorded and output locally. Since an emergency contact e-mail carrying the received image information is transmitted to the e-mail address registered in the subaddress, the received original is recorded and output in the network facsimile apparatus FXa, so the network facsimile apparatus FXa The user can be provided with emergency contact information, and more reliable emergency contact communication can be performed.

  If “all destinations” is registered as an attribute for the destination subaddress at that time, and the result of determination 248 is YES, “transfer” is registered as the attribute value from the subaddress distribution table. The corresponding mail address (forwarding mail address) is acquired from all items (process 270), the header information of the e-mail is created (process 271), and the received image information stored at that time is converted into TIFF image data. (Process 272), the TIFF format image data is MIME-converted to create binary part data of the body information of the email (Process 273), and the email created as described above is transmitted. (Processing 274).

  In this way, when the subaddress in which “all destinations” is registered as an attribute in the subaddress distribution table is notified as the subaddress, the mail addresses of all transfer destinations registered in the subaddress distribution table are as follows: Since an e-mail carrying the received image information is transmitted, it is very convenient.
