This program will be described as an example of being stored in the recording medium 18 in the form of a program code that can be read by the CPU 11, but it is not necessary to store all the functions in the recording medium 18, and if necessary, WA part or all of it
Network such as N, LAN, and the Internet 2 above
It may be realized by receiving from the communication control unit 17 via 0.

That is, the CPU 11 of the center 10 periodically checks the mail through the communication control unit 17, and when the mail has arrived in the mailbox, receives the mail and stores it in the RAM 15 or the recording medium 18. (Step S101).

Then, this saved received mail is sent to the Web.
It is determined whether the email is a conversion instruction mail (step S1).
02). Here, in the received mail, as shown in FIG. 5B, the “subject name” describes the Web conversion instruction and the URL of the page to be imported. It is possible to determine whether or not it is an instruction mail.

If the received mail is not the Web conversion instruction mail, the determination result of step S102 is NO.
In this case, it is assumed that the received mail is a normal mail and normal mail processing is executed (step S
103) and ends the processing of this flowchart.

When the received mail is the Web conversion instruction mail, the determination result of step S102 is YES, and in this case, it is further determined whether the user who has transmitted the Web conversion instruction mail is a registered user. It is determined (step S104). This determination is made by searching the user registration information table 18A stored in the recording medium 18 and determining whether or not the mail address described in the "sender (From)" of the received mail is registered. It can be carried out. If the user is not a registered user, the determination result of step S104 is NO.
In this case, the received mail is treated as a normal mail, the process proceeds to step S103, and the normal mail process is performed.

On the other hand, when it is the Web conversion instruction mail from the registered user, the above step S104.
Is YES, and in this case, the URL of the page to be imported, which is described in the "subject" of the saved Web conversion mail is extracted (step S105), and the Web information corresponding to the extracted URL is read out. Then, the source file is stored in the RAM 15 or the recording medium 38 (step S106). As the Web information to be read and stored, the source file is used as an example in the following description, but the present invention is not limited thereto and is displayed on the display screen of the display unit 13. Needless to say, it may be other information such as character information of the Web page. In this way, for example, a web page as shown in FIG. 5C is saved. Note that in FIG. 5C, the characters that are identified and displayed by the rectangular frame and the underline indicate that link information to another Web page is provided.

Then, it is determined whether or not the "subject" of the saved Web-converted mail includes character information with link information (step S107). Here, if the link information is not included in the character information, the determination result in step S107 is NO, and in this case, the email described in the "sender" of the saved Web-converted email. Extract address (step S
108). Then, the communication carrier is specified from the domain name included in the extracted email address, and the recording medium 18
The communication processing method, that is, the maximum number of characters to be fetched is determined by the communication carrier table 18B stored in (step S
109), and the conversion is performed according to the determined conversion method (step S110).

The conversion process according to this conversion method is shown in FIG.
(B) of FIG.

First, the corresponding file is read from a plurality of Web information source files stored in the RAM 15 or the recording medium 38 (step S110A).
That is, the source file of the Web information corresponding to the URL designated by the "subject name" is read. Then, the text display portion is extracted from the read source file (step S110B). That is, the content of only text that is appropriate for browsing by the mobile phone device, PHS 30A, and mobile information terminal device 30B is extracted. For example, if the web page is as shown in FIG.
Text data as shown in FIG. 7A is extracted.

Link information is extracted from the read source file and registered in the recording medium 18 as a link information table 18C as shown in FIG. 2C (step S110C). That is, the characters with the link information and the address (URL) of the link destination are extracted and stored in association with each other.

Thereafter, the blank lines in the extracted text display portion are deleted to fill the lines (step S110D).
Further, the link information stored as the link information table 18C is attached as an attachment file to the Web conversion instruction reply mail which is a reply mail to the Web conversion instruction mail (step S11E).

Then, the text data of the extracted and processed text display portion is converted to the above-mentioned step S109 of FIG.
It is determined whether or not the conversion method determined in step 1, that is, the maximum number of characters to be captured is determined (step S110F), and if so,
The determination result of step S110F is YES, and in this case, the process returns to the upper routine.

If it is not within the maximum number of captured characters, the determination result of step S110F is NO, and in this case, the extracted and processed text data is further processed so as to fit within the maximum number of captured characters. Then (step S110G), the process returns to the upper routine.
In this case, as a processing method, there is a method of truncating the maximum number of characters to be captured, or a method of dividing the blocks by the maximum number of characters to be transmitted by e-mail for each block. In the present embodiment, the latter is adopted.

If the conversion is performed according to the conversion method in this manner, then, as shown in FIG. 7B, the extracted and processed text data is added to the Web with the link information attached as an attached file. It is set as the text of the conversion instruction reply mail, and the sender of the Web conversion instruction mail is set as the destination, and the Web conversion instruction reply mail is transmitted (step S111). In order to transmit text data exceeding the maximum number of characters to be fetched as described above, when dividing into blocks by the maximum number of characters to be fetched and sending mail by each block, as shown in FIG. 3B. In addition, character information (“(1)” in the example of this figure) indicating the number of the block is added to the “subject name”.

Then, the charging process is performed (step S112). This is the user registration information table 18 described above.
In the data of the registered user of A, the service fee for this time is registered, and the total is updated to the sum of the fees. After that, the registration information in the user registration information table 18A is updated (step S11).
3). This is to indicate which Web page was converted and provided in the data of the registered user in the user registration information table 18A in association with the current service charge registered in the charging process in step S112. This is a process of registering a URL and the like in the conversion history. Then, when the updating of the user registration information is completed, the processing of this flowchart is completed.

FIG. 8 shows a We according to an embodiment of the present invention.
b The mobile phone device or P in the information display conversion system
It is a flow chart for explaining a program for making a computer which constitutes HS30A and personal digital assistant device 30B realize each function of reception operation. This program will be described as an example of being stored in the recording medium 38 in the form of a program code that can be read by the CPU 31, but it is not necessary to store all the functions in the recording medium 38, and if necessary, A part or all of them may be realized by receiving them from the communication control unit 37 via a network such as WAN or LAN or the Internet 20.

That is, the mail receiving process is performed, and all the received mails are stored in the RAM 35 or the recording medium 38 (step S351). Then, it is determined whether or not the stored received mail includes the Web conversion instruction reply mail from the center 10 (step S352). This Web
Whether it is a conversion instruction reply mail can be determined by whether or not the URL is described in the “subject name”.

Here, when there is no Web conversion instruction reply mail, the determination result of the above step S352 is NO, and each is displayed and output as a normal mail (step S353), and the processing of this flowchart ends.

On the other hand, if there is a Web conversion instruction reply mail, the determination result in step S352 is YES, and in this case, the text data that is the text of the Web conversion instruction reply mail is output. It is displayed on the display unit of the unit 33 (step S354).

Further, based on the link information attached as an attachment file to the Web conversion instruction reply mail, the characters with the link information in the displayed text data are identified and displayed (step S355).

As a result, as shown in FIG. 7C,
The contents of the Web page are displayed as text on the display unit 33A, which has a limited size, and the characters with link information are displayed as the identification display 33B.

Thereafter, it is determined whether or not the character designated as the identification display 33B has been designated by the input section 32 (step S356). If such a designation operation has not been performed, the determination result is NO, Further, it is determined whether or not there is a next divided block (step S35).
7). This can be determined by whether or not the “subject” of the received Web conversion instruction reply mail includes character information.

Then, when the Web conversion instruction reply mail is not divided and transmitted, the above step S3 is performed.
The determination result in 57 is NO, and in this case, the processing of this flowchart ends.

On the other hand, when the Web conversion instruction reply mail is divided and sent, the determination result in step S357 is YES, and in this case, the next divided data by the input unit 32 is sent. In response to the display instruction (step S358), the content of the Web conversion instruction reply mail of the next divided block is read from the saved mail (step S359). Since the character information included in the “subject” indicates the order as described above, it is possible to easily determine the next item after the currently displayed item. Then, in step S354 described above.
By returning to, the contents read above are displayed.

In this way, when all the divided contents are displayed, since the "subject name" does not include character information in the Web conversion instruction reply mail of the last divided block, there is no next divided block in step S357. Is determined, and the processing of this flowchart is ended.

On the other hand, when it is determined in step S356 that the character displayed as the identification display 33B has been designated and operated, the determination result is YES. In this case, the outgoing mail creation screen is displayed (step S36).
0) Further, the mail address of the center 10 is read from the ROM 34 or RAM 35, or the recording medium 38 (step S361).

Then, the "destination (To)" of the outgoing mail
At the same time, the read mail address of the center 10 is automatically input, and the Web conversion instruction and the URL described in the "Subject" of the received mail are automatically input in the "Subject" (step S362). Furthermore, as shown in FIG. 3 (C), the “subject name” automatically includes the characters (CD / DVD in the figure) used as the identification display 33B sandwiched by a predetermined identification symbol (#). Is entered.

Then, in response to the transmission instruction operation of the input unit 32 by the user (step S363), the created transmission mail is transmitted as a new Web conversion instruction mail (step S364), and the processing of this flowchart is performed. finish.

When the mail sent in response to the designation of the character designated as the identification display 33B is received, the center 10 displays the character with the link information added to the "subject" in step S107 in FIG. Since it is determined that the information is included, the determination result in this step is YES.
