The present invention relates to a communication device capable of exchanging information between an electronic information medium such as an e-mail medium and a facsimile medium.
[0002] [Conventional Technology] In recent years, information retrieval of electronic information such as e-mail via the Internet has become common in addition to information exchange means such as facsimile and telephone via a telephone line. Focusing on e-mail, it is possible to exchange not only textual information but also information in various data formats such as images, voices, and computer data. To describe the current usage of e-mail within a company, each e-mail user usually has his or her own post office (also known as a mailbox (PO Box)) within an e-mail server installed within the company. ) Is provided. E-mails sent to each person are temporarily stored in the post office. After that, it is pulled out by the e-mail client software installed in an in-house personal computer (hereinafter referred to as a PC) that is directly connected to the e-mail server via LAN or the Internet or a telephone line. However, access to the post office from outside the company via a telephone line or the Internet may leak information inside the company to the outside.
[0003] Therefore, there are few companies that allow the supplementary writing of internal e-mail from outside the company. On the other hand, even companies that allow access from outside the company will introduce a system that encrypts e-mail, limit access from the outside to only telephone lines, and change the password to access each time. There is a dedicated access server that allows you to use a disposable password.
[0004] [Problems to be Solved by the Invention] However, in the above-mentioned conventional example, (1) a system for extracting e-mails such as e-mails addressed to oneself from outside the company affects the entire electronic information system and causes a high operating cost. Equipment installation cost is high.
Taking e-mail as an example, looking at the in-house e-mail system, in order to construct a system for extracting electronic information such as in-house e-mail from outside the company, the above-mentioned e-mail is encrypted. It is necessary to newly install a dedicated access server for access by the system to be changed and the telephone line from the outside to the inside.
[0006] Therefore, introducing the hardware and software necessary for it requires a considerable equipment introduction cost and an operation cost for maintaining the system.
[0007] For example, the introduction of software for encrypting e-mail requires not only changing the software of the e-mail server but also updating the software of the e-mail client on all the PCs used by the e-mail users in the company. ..
[0008] Further, looking at access means from outside the company, a mobile PC or a mobile terminal equipped with software for extracting electronic information is required. For example, it is relatively easy for a salesperson to introduce a mobile PC or mobile terminal for use outside the company. Because the use of mobile terminals during working hours, access to electronic information such as in-house e-mail access is a daily occurrence, and to sales staff who are responsible for providing information to customers. This is because information investment leads directly to operating profit such as expansion of customers.
[0009] On the other hand, people in the research and development department can perform creative production work such as ideas for new products by accessing in-house information during non-working hours. However, in this work, access to internal information does not directly lead to the profit of the company, but only indirectly to the profit of the company, and it is unlikely to be a trigger for the company to invest in information.
[0010] Also, assuming a company whose access to the above-mentioned e-mail is prohibited from the outside, (2) In order to obtain the e-mail in the company from the outside, it is necessary to go through a person inside the company. , It is difficult to get reliable e-mail.
[0011] For example, when confirming an e-mail addressed to oneself outside the company, the person inside the company must be contacted and verbally told the contents, or the e-mail taken out must be sent separately. .. Also, if it is a holiday, the person must go to the office.
[0012] [Means for Solving Problems] In the present invention, the communication device is provided with a first connection means for connecting to a local area network or a computer network including the Internet, a second connection means for connecting to a public network, and an e-mail server of the computer network. A post-office designation means for designating one of the post-offices, an e-mail receiving means for receiving e-mail data stored in the post-office designated by the post-office designation means from the e-mail server, and the e-mail. By a conversion means for converting the e-mail data received by the mail receiving means into facsimile image data, a transmission means for facsimile transmitting the image data converted by the conversion means to a designated destination, and the post-office designated means. Receiving means for holding information in which the post office to be designated and the destination for facsimile transmission by the transmitting means are associated with each other, and the e-mail data received by the e-mail receiving means is facsimile image data by the conversion means. The e-mail receiving means receives the e-mail, and the e-mail data determined to be convertible by the e-mail receiving means is converted into facsimile image data and transmitted. The means is such that the facsimile image data converted by the conversion means based on the determination by the determination means is facsimile-transmitted to a destination designated based on the information held by the holding means.
[0013] Further, a means for receiving a remote instruction from the public network is provided so that e-mail data can be extracted from the post office of the e-mail server designated by the remote instruction.
[0014] Further, the user identification information and the password information are received as the remote instruction, and a post office corresponding to the received user identification information exists in the e-mail server, and a password preset for the post office exists. When the information and the received password information match, the e-mail data is extracted from the e-mail server.
[0015] Further, when the received remote instruction includes the information of the destination to be facsimile-transmitted, the converted image data is transmitted to the destination corresponding to the destination information.
[0016] Further, when the received remote instruction does not include the destination information for facsimile transmission, the converted image data is transmitted to a preset destination.
[0017] Further, the remote instruction is received from the public network, the e-mail data is extracted from the e-mail server according to the received remote instruction, the image conversion by the conversion means is completed, and the image data to be facsimile-transmitted is obtained. When the connection with the public network is continued at the time of preparation, the facsimile transmission via the public network is executed as it is, and on the other hand, to the set destination where the connection with the public network is not continued. The converted image data is automatically called and the converted image data is sent by facsimile.
[0018] Further, when new e-mail data is not held in the post office of the e-mail server as a result of accessing the e-mail server by the e-mail access means, a new e-mail is sent to the destination for facsimile transmission. It provides a means for notifying that mail data is not retained.
[0019] Further, when a means for receiving the caller identification information from the public network is provided and the remote instruction does not include the destination information to be facsimile-transmitted, the converted image data is sent to the destination of the caller identification information. It is intended to be sent.
[0020] Further, when the received remote instruction includes information on a method of withdrawing e-mail data from the post office of the e-mail server, the e-mail data is according to a method corresponding to the information on the withdrawal method. It is intended to bring out.
[0021] Further, when the remote instruction does not include information regarding the withdrawal method, the e-mail data is withdrawn according to a preset e-mail data withdrawal method.

[0063] Then, in the communication sequence, the CPU 10-3 of the e-mail facsimile apparatus 1-11 is then subjected to the e-mail server 1-10 via the line I / F section 10-6 or the LAN I / F section 10-14. To send an email list notification request (2-4) and receive email list data from email servers 1-10 (2-5). CPU10-3 of the e-mail facsimile apparatus 1-11 analyzes the contents of the received e-mail list data and sets the information of 3 items as the number of e-mails in the number of e-mails 3-2 in the e-mail list table of the management data in Fig. 3. Then, mail numbers 1, 2, and 3 and mail data capacity, for example, mail data capacity 1K bytes (facsimile image data 30K bytes), 2K bytes (color image data 40K bytes), 500K bytes are mail array [0], [ Set in the corresponding area of 1] and [2] (2-50).
Next, the processing of the first mail (the e-mail data includes text data and facsimile data as shown in FIG. 4) will be described. CPU10-3 checks the completion of all mail processing (2-51), and in this case it has not completed yet, so the free memory capacity (free memory capacity 3-1 of the management data in Fig. 3, 300 Kbytes in this case) ) And the data capacity of the first mail (the mail data capacity of the management data mail array [0] in Fig. 3, 1K bytes in this case) (2-52), and the free memory capacity is sufficient, so it is electronic. Moved to the mail data reception process (2-54), and in this mail data reception process, the mail server 1-10 was made to send the transmission request of the mail data 1 (2-6), and the mail server 1 Receive email data 1 from -10 (2-7). At that time, set 1 to the number of external bodies 3-14 (Fig. 3) of the e-mail list table, set the text to the data type 3-20 of the body array [0], and set 1 Kbyte of free memory to the data capacity 3-21. Acquired, set the address in the received text data storage area pointer 3-15, and store the received e-mail data 1 (text) in this acquired memory.
By the way, the received data shown in FIG. 4 has a header portion from From: aaa@bbb.ccc.dd.ee to Message-Id: <19960704215959.TAA99999@xxx.ccc.dd.ee>. The first "--- Boundary ---" to the third "--- Boundary ---" is called the body part, and "--- Boundary ---" has two body parts. The first is referred to as the body part 1 and the second is referred to as the body part 2.
[0066] Finally, 2 is set in the number of external bodies 3-14. The contents of the data of the body part 1 and the body part 2 are different from each other, and the body part 1 is the Japanese text data shown by "Content-type: Text / Plain; charset = iso-2022-jp". The header part and the body part 1 are converted into text as shown in FIG. On the other hand, the body part 2 is Content-type: message / external-body; access-type = ANON-FTP; site = aaa.bbb.cc.dd; directory = fax name = file19960704215959.xxx content- It is an external file defined by type: image / iff, and the identifier indicating the content is content-type: image / iff, which indicates that it is an image data file. Incidentally, it is the facsimile image data shown in FIG. 6 having a resolution of 8 × 3.85 ppm, a coding method of MH (Modified Huffman), and a main scanning pixel number of 1728dot.
Next, the CPU 10-3 shifts to the e-mail data analysis process (2-55) and analyzes the body portion 1 of the e-mail data 1.
[0068] From the description "boundary =" --- Boundary --- "", since it is "Content-type: Text / Plain; charset = iso-2022-jp", it can be understood that it is text data and image data can be expanded. Therefore, the process proceeds to step 2-62, and the data of "OK" is stored in the processing result 3-23 of the body array [0], and it is determined whether or not the file reception is necessary (2-62). In the case of the body part 1 of the e-mail data 1, since it is not necessary to receive the file, the process proceeds to the image data expansion process of step 2-58.
[0069] When shifting to the image data expansion process, CPU10-3 sets "Text / Plain; charset = iso-2022-jp" to the data type 3-20, acquires one page management data, and manages the page. Set the data pointer 3-22 to that address. Then, CPU10-3 starts from the text in the header part of Fig. 4 and the line after "Content-type: Text / Plain; charset = iso-2022-jp" to before "--- Boundary ---". Generate text data as shown in Fig. 5 from the text of. Next, by indexing the text with a bitmap of the characters of ROM10-2, the resolution is "8 x 3.85" and the number of main scanning pixels is "1728". A bitmap image of "pel / mm" is generated, converted into facsimile image data of the coding method "MH" by the compression / decompression unit 10-10, and data is set there while acquiring an image data block. CPU10-3 sets the values of the number of main scanning pixels 14-2, the resolution 14-3, and the coding method 14-4 of the page management record to the above-mentioned values, respectively, and sets the image data block of the image data block pointer 14-6 to the image data block. It is connected to the end of the queue. At the same time, the image data size 14-5 is also added by 8 bytes, the image data expansion process is executed in this way, and the storage memory corresponding to the image data block that acquired the expanded image data. It is stored in the area of 10-5, and when the image data expansion process is completed, the process proceeds to step 2-59.
[0070] In step 2-59, the CPU 10-3 determines whether or not all the partial processing has been completed. In this case, since the partial processing is not completed, the process proceeds to the analysis processing of the e-mail data in step 2-55, and the body part 2 of FIG. 4 of the e-mail data 1 is analyzed.
[0071] In the analysis of the body portion 2, it is found that the data is image data from the description of "Content-type: image / iff". Furthermore, the data extracted from the description of Content-type: message / external-body; access-type = ANON-FTP; site = aaa.bbb.cc.dd; directory = fax name = file19960704215959.xxx Is an external file "massage / external-body", which is a file extracted by anonymous FTP (file transfer procedure) "access-type = ANON-FTP", and has a host name "aaa" in the domain "bbb.cc.dd". You can see that the file name in the directory "fax" on the computer's auxiliary storage is "file19960704215959.xxx".
Therefore, in step 2-62, the CPU 10-3 determines that the file reception is necessary, receives the file, and stores the received file in the RAM 10-4 (2-63).
Next, in CPU10-3, the file received in step 2-63 has a resolution of 8 × 3.85 ppm, an encoding method of MH, and a number of main scanning pixels of 1728 dots as described above. Since it is the facsimile image shown in Fig. 6, it is judged that it can be expanded (2-64). Then, CPU10-3 performs image data expansion processing of the received file (2-65).
[0074] In the process of step 2-65, the CPU 10-3 acquires the page management data, sets the data such as the resolution described above in the acquired page management data, and acquires the image data block from the storage memory 10-5. Then, while storing the facsimile image data taken out from the received file data in the image data block of the storage memory 10-5, the image data block queue is generated, and the image data block pointer of the body array [1] in FIG. 3 is generated. Set to and set "OK" data in the processing result.
[0075] Then, in step 2-60, the CPU 10-3 determines whether or not there is data that cannot be analyzed or expanded. In this case, since the body part 2 of the e-mail data 1 could be completely expanded into the facsimile image data, in step 2-61, the "deletion request" is set to the deletion mode 3-12 by the deletion process according to the deletion mode. Then, the mail server 1-10 is sent a request to delete the mail data 1 (2-8). When the e-mail server 1-10 receives the deletion request of the e-mail data 1, the e-mail server 1-10 deletes the e-mail data 1.
[0076] In the incoming call processing in the flow of FIGS. 9 and 10 described later, when the e-mail data withdrawal method is specified as a remote instruction, the CPU 10-3 electronically follows the specified withdrawal method. Whether or not to extract the mail data (extract all the email data / extract only the header part) and set the deletion request also follows the specified extraction method.
Next, the processing of the second mail (external file that cannot be interpreted as text) will be described. Since the processing sequence of the text data is the same as that of the e-mail data 1 described above, the description thereof will be omitted and the text analysis processing will be described first.
[0078] When the CPU 10-3 executes the analysis process (2-55) of the e-mail data, it is found that the process of the color image data file must be executed, and this color image data file cannot be processed. , Set the information of "Color image processing impossible" to the processing status of the mail array [1] of the management data in Fig. 3, and "Color images with the following contents cannot be processed by this device" as shown in Fig. 7. An alternative character string such as "." Is embedded in the received text data stored in the memory corresponding to the data area pointer of the body array [1] of the mail array [1], and the body array [0] of the mail array [1] is embedded. Set the information of "There is unanalyzable data" in the processing result and processing status of, set the information of "Not deleted" in the delete mode (2-56, 2-57), and expand it to the image data (2-56, 2-57). 58).
[0079] Then, in step 2-59, since the next partial processing does not exist, CPU10-3 shifts to step 2-60, and the deletion mode is "do not delete", so that the email server 1-10 Then, the process proceeds to step 2-51 without sending the deletion request of the e-mail data 2.
[0080] FIG. 7 is a diagram showing the contents expanded into the image data of the e-mail data 2.
Next, the third mail (the amount of facsimile image data to be received is too large to be received) processing will be described.
[0082] In this case, in the memory capacity check (2-51), the CPU 10-3 receives all the data because the free memory capacity at that time is 227 Kbytes and the received e-mail data is 500 Kbytes. Can not do it. Therefore, only the header part of the e-mail (for example, the text data up to "--- Boundary ---" in Fig. 4) is received, and "memory full" information is set in the processing status of the e-mail array [2]. (2-53). After that, set the processing result and processing status of the body array [0] of the mail array [2] to the information of "memory full", set the information of "not deleted" to the delete mode, and "receive when the memory is full". Embed a message such as "Cannot" in the text of the received mail data (2-56, 2-57), and execute the expansion process to expand the text of the received mail data into the image data (2-58). And CPU10-3 does not send a deletion request for email data 3 to email servers 1-10 because the delete mode is "do not delete" (2-60).
When the processing of all the e-mail data is completed in this way, the CPU 10-3 of the e-mail facsimile device causes the e-mail server 1-10 to send the end request of the e-mail data service, and the e-mail server 1-10. When a positive response is received from, the connection release procedure is executed and the process ends (2-13).
[0084] It should be noted that the user determines whether the timing of making the deletion request to the e-mail servers 1-10 is when the e-mail data is received, when it is expanded into the facsimile image data, or after it is normally printed. Can be freely selected.
[0085] Further, the e-mail facsimile apparatus 1-11 of the present embodiment can print (record) the image data developed in the above-described processing by the printer unit 10-11, and further, the e-mail of FIG. 3 With reference to the list data, the e-mail list shown in FIG. 8 is expanded into image data, printed by the printer unit 10-11, or transmitted to an external facsimile machine in response to a remote instruction.
Next, with respect to various processes executed by the e-mail facsimile apparatus 1-11 of the present embodiment with respect to the e-mail information extracted by accessing the e-mail server 1-10, FIGS. 9 and 10 show. This will be described with reference to the flowchart.
[0087] Before explaining the flow of FIGS. 9 and 10, it relates to a remote instruction (user identification information, password information, online instruction facsimile destination, mail withdrawal method (content)) notified from a remote telephone or a facsimile machine. The data format will be described.
[0088] # 0 of # 0aaaa indicates an identifier of user identification information, and aaaa is a user identification number.
[0089] # 1 of # 1bbbb indicates an identifier of password information, and bbbb indicates a password number.
[0090] # 2 of # 2ccccccccc indicates an identifier of an online instruction facsimile destination, and ccccccccc indicates a facsimile destination number.
[0091] # 3 of # 3de indicates the identifier of the mail withdrawal method, d indicates the entire mail when 0, only the mail header when 1, and e indicates the electronic. Indicates whether to delete the e-mail file in the e-mail server when the mail is pulled out from the server, or "0" to not delete it.
9 and 10 are flowcharts showing the incoming call processing executed by the CPU 10-3 when there is an incoming call from the public line (PSTN or ISDN) to the e-mail facsimile apparatus 1-11. Yes, the processing shown in this flow is executed by the computer program stored in ROM10-2.
[0093] In step 9-2, the CPU 10-3 determines whether or not there is an incoming call from the public line (PSTN or ISDN), and when an incoming signal is output from the line I / F unit 10-6, the public line Judged as an incoming call. When there is an incoming call from a public line, in step 9-3, it is confirmed whether or not it is an information receiving terminal activation signal of the caller ID notification service. This e-mail facsimile machine has a function corresponding to the caller's telephone number notification service that notifies the caller's telephone number, which is one of the services of the public network. When the information receiving terminal activation signal is received, the CPU 10-3 determines in step 9-4 whether or not the caller's telephone number is normally received from the public line, and the caller's telephone number is normally received. Then, in step 9-5, the received caller telephone number information is temporarily stored in RAM 10-4 as the information of the online instruction facsimile destination, and in step 9-6, the line I / F section 10-6 Determines whether or not a secondary incoming call from the public line has been detected, and if a secondary incoming call is detected, the process proceeds to steps 9-7.
[0094] If the information receiving terminal activation signal from the public line is not received in step 9-3, the process proceeds to step 9-7. If the public line is ISDN, the caller identification information for identifying the caller is notified when an incoming call arrives, so the processes of steps 9-3, 9-4, and 9-6 are unnecessary. , The notified caller identification information is stored in RAM 10-4 as the information of the online instruction facsimile destination in step 9-5, and the process proceeds to step 9-7.
[0095] In step 9-7, the CPU 10-3 causes the line I / F unit 10-6 to transmit the voice guidance 1 (voice message 1) to the public line. Voice guidance 1 is, for example, "E-mail facsimile conversion service is possible. When using the e-mail conversion service, enter a 4-digit user number following # 0 and a 4-digit password number following # 1. Please enter the phone number of the fax destination after # 2. If you have already registered the fax destination, you do not need to enter the phone number of the fax destination. If you enter # 30, it is currently The entire contents of the e-mail posted in the mailbox will be sent by fax. Please enter # at the end. "
Next, in step 9-8, the CPU 10-3 determines whether or not the specified time has elapsed since the transmission of the voice guidance 1 was started, and if the specified time has elapsed, step 9- Proceed to 19 to perform the facsimile reception process. If the specified time has not elapsed, it is determined in step 9-9 whether or not a tone signal (CNG signal) indicating that the source is a facsimile device has been received, and in step 9-10, the tone is determined. It is determined whether or not a signal (DTMF signal) has been received, and in step 9-11, it is determined whether or not a single # tone signal has been received, and a single # tone signal is received. Then, it is determined that the input of the remote instruction by the DTMF signal is completed, and the process proceeds to step 9-12. When the CNG signal is received, the process proceeds from step 9-9 to step 9-19 to execute the facsimile reception process. Further, the received DTMF signal is stored in RAM 10-4 as data of the type of the tone signal.
[0097] In step 9-12, the CPU 10-3 analyzes the DTMF signal data received and stored in the RAM 10-4. Then, in step 9-13, it is determined whether or not the received DTMF signal data can be analyzed, and if it cannot be analyzed, in step 9-20, voice guidance 2 (for example, "How to input a tone signal") Is wrong. Please try again. , Etc.) is sent to the line by the line I / F section 10-6, and in step 9-23, the captured public line is released to process the incoming call. finish.
[0098] Further, when the DTMF signal data received in step 9-13 can be analyzed, the CPU 10-3 performs the user identification number received as the DTMF signal and the management data in FIG. 12 in step 9-14. The user identification information of each of the 10 post-office sequences in is compared with each other to determine whether or not there is a match. If there is no match for the user identification information, CPU10-3 gives voice guidance 3 (for example, a voice message such as "The user identification number is incorrect. Please enter it again.") In step 9-21. The line I / F section 10-6 sends the line to the line, opens the line, and ends the incoming call processing.
[0099] Further, if there is a match for the user identification information, the CPU 10-3 sets the password information received as the DTMF signal in step 9-15 and the password information of the post-office arrangement of the matching user identification information. If the password information does not match, in step 9-22, voice guidance 4 (for example, a voice message such as "The password number is incorrect. Please enter it again.") Is sent to the line I / F. Part 10-6 sends the line to the line, opens the line, and ends the incoming call processing.
[0100] In steps 9-20, 9-21, and 9-22, after sending the voice guidance, the process may proceed to step 9-7, and the DTMF signal reception process may be performed again.
[0101] Further, when the password information matches, the CPU 10-3 determines whether or not the online instruction facsimile destination is specified in step 9-16, and in step 9-17, the online instruction facsimile destination is used as a DTMF signal. If is specified, the destination information, and if the caller ID is stored in RAM10-4 as an online instruction facsimile destination in step 9-5, the destination information is a post-office array that matches the user identification number. Online instructions Store in the fax destination.
[0102] Then, in step 9-24, CPU10-3 is voice guidance 5 (for example, "Processing has been accepted. Please wait for the completion of processing while holding the handset, or hang up the handset once." The content of the e-mail is then automatically sent to the customer's facsimile. , Etc.) is sent to the line by the line I / F section 10-6.
[0103] In step 9-25, the processing shown in the communication procedure sequence and the flowchart of FIG. 2 is executed, and from the e-mail server of the 11-2 e-mail server IP address of the management data of FIG. 11, to step 9-14. Specify the post office name of the mail post array with the same user identification number, and retrieve the mail data from the mail servers 1-10. When the extraction of the e-mail data and its processing (expansion processing to the image data) are completed, the process proceeds to steps 9-26.
[0104] In step 9-26, the CPU 10-3 determines whether or not the line is open, and if the line is not open, in step 9-30, the voice guidance 6 (for example, "facsimile image" A voice message such as "You are ready. Press the start button of your fax machine and hang up the handset.") Is sent to the line by the line I / F section 10-6, and in steps 9-28, Facsimile image data (e-mail data converted to facsimile image data) stored in the storage memory 10-5 is transmitted.
[0105] Further, if the line is opened in step 9-26, the CPU 10-3 is an online instruction facsimile destination of the mail post array in which the user identification number matches in step 9-14 in step 9-27. Alternatively, the line I / F section 10-6 automatically calls (dial) the facsimile destination that has been set as the default, and in steps 9-28, the facsimile transmission process of the expanded image data is executed, and the facsimile is performed. When the transmission is completed, the captured line is released and the incoming call processing is completed.
[0106] In the process of step 9-25, if the e-mail data does not exist in the designated post office of the e-mail server 1-10, the voice guidance sending process of step 9-30 "to the designated post office". Is not available for new e-mail data. And other voice messages are sent to end the incoming call processing, while steps 9-26 to 9-27 and 9-28 are specified. There is no new e-mail data in the post office. An image message such as "" is generated and sent by facsimile.
[0107] According to the above e-mail facsimile machine, (1) A system administrator who manages and operates an information system such as an in-house LAN or an e-mail system uses a telephone line (or ISDN line) from a user to an e-mail server. When there is an access request from the outside via the system, it is possible to respond to the access request at low cost of system installation and operation.
[0108] In order to construct a system for extracting electronic information such as internal e-mail from outside the company, a system for encrypting e-mail as described above or a dedicated system for accessing from the outside to the inside by a telephone line is used. There is no need to install a new access server, just connect this e-mail facsimile machine to the in-house computer network. Therefore, there is almost no change in the conventional electronic information system such as e-mail, and since this e-mail facsimile machine is an extended device of the facsimile machine, it can be easily introduced into the system and the cost is low. Further, in terms of operation, the maintenance of the e-mail facsimile machine may be performed, and the maintenance of the system can be easily completed.
(2) A facsimile machine that is already widespread in the general public network can be added as an e-mail client, and it is possible to withdraw e-mail reliably and safely against information leakage, which greatly increases the number of e-mail users. It leads to convenient convenience.
[0110] Existing facsimile terminals have become terminals for withdrawing e-mail equivalent to e-mail clients, so that e-mail users do not have to carry a dedicated e-mail withdrawal terminal at all times, and wherever there is a facsimile terminal, anytime. E-mail can be withdrawn. In addition, by introducing this e-mail facsimile device into a LAN system, it becomes possible to obtain e-mail information reliably and promptly without human intervention when extracting e-mail information from the outside. Further, since the e-mail is once converted into a facsimile code and transmitted by a telephone line, the possibility of information leakage is greatly reduced as compared with the information transmission via the Internet. Therefore, the convenience and certainty of information acquisition by e-mail users and the safety of information leakage are greatly improved.
[0111] Further, by adding a function of encrypting the facsimile code to be transmitted to the above-mentioned e-mail facsimile apparatus, the airtightness of the information is further improved.
[0112] Although the above-described embodiment has been described by taking an e-mail facsimile machine as an example, the functions of the above-mentioned e-mail facsimile machine can also be realized by installing the e-mail facsimile machine as an application program on a personal computer.
[0113] In addition, since the e-mail list, which is a list of headers of the e-mail data extracted from the e-mail server, is recorded and output, the e-mail can be managed easily and the e-mail data can be reliably retrieved. be able to.
[0114] In addition, if the e-mail data extracted from the e-mail server contains contents that cannot be interpreted by the e-mail facsimile apparatus, or if the memory capacity for receiving the e-mail data cannot be secured, a message indicating that is displayed. Since the output is configured so that the e-mail data is not deleted from the e-mail server, the operator can withdraw the e-mail by another device, or withdraw the e-mail data when the memory capacity is free. E-mail data can be obtained.
[0115] Further, the present invention is not limited to the above-described embodiment, and various modifications can be made.
[Effect of the Invention] As described above, according to the present invention, since the electronic mail data of the computer network is converted into the facsimile image data and transmitted by the facsimile, the system configuration can be simplified and the confidentiality of the information can be improved. It does not decrease. Moreover, the post office and the facsimile destination when receiving the e-mail are associated with each other.<u style="single">information</u>Since it is retained and faxed to the destination based on it, flexible operation according to the post office becomes possible.<u style="single">In addition, it is possible to determine whether or not the received e-mail data can be converted into facsimile image data, and transmit the converted facsimile image data based on the determination.</u>BRIEF DESCRIPTION OF THE DRAWINGS [Fig. 1] Fig. 1 is a diagram showing a connection mode of an e-mail facsimile apparatus with a network.
