Step T9: (Generation of Display Restriction Information for Specific E-mail Magazine, etc.) The display restriction information registration means 54 stores the flag value “0” in the restriction target flag column 61 and the flag value “0” in the e-mail magazine identification information column 62 in the above-described step T7. The acquired URL is displayed in the display section column 63 with the display section code selected in step T8, the keyword fields 64-1 to 64-n (n ≦ 5) are displayed with the keywords displayed in step T8, and the display condition section. In 65, the display restriction information 60 for the specific mail magazine storing the minimum number of keywords input in step T8 is set as the display restriction target, and registered in the display restriction information storage area 447 of the storage memory 44.

Step T10: (Determination of Display Restriction Target End, etc.) The display restriction information registering means 54 terminates the display restriction information registration processing when the subscriber performs an operation to end the display restriction information registration operation. If not, the e-mail magazine reception list is displayed to prompt the user to select an e-mail magazine whose display is to be restricted, and when the subscriber selects the e-mail magazine, the process transits to T6 in order to input display restriction information of the next e-mail magazine.

With the above-described configuration, by limiting the display on the receiving terminal side, a mail magazine or mail containing only information of interest to the subscriber can be obtained from various mail magazines distributed as usual without load on the mail magazine distributor. Since the parts of the magazine are extracted and displayed, subscribers can easily view only the necessary e-mail magazines and the necessary parts in the e-mail magazines, improving the actual reading rate of e-mail magazines and effectively using e-mail magazines realizable.

<Application Example to Screen Saver> Unless an operation for changing the screen for a predetermined time or more is performed for a predetermined time in order to prevent screen burn-in or power saving when the operation is stopped, a predetermined pattern or the like is automatically dynamically generated. There is a screen save technology for displaying a pattern and stopping the display of a pattern or the like when an operation is started and returning to an original state. At the time of this screen save operation, various mail magazines in which desired articles (topics and information) are extracted can be dynamically displayed by the information browsing method of the present invention.

FIG. 8 is a schematic flowchart showing an outline operation when displaying an e-mail magazine as a screen saver. FIG. 8A shows an operation at the time of e-mail magazine display registration, and FIG. 9 is a flowchart illustrating an operation when displaying. In this example, a screen saver setting program and a screen saver program are installed in the terminal 40. The screen saver browsing program used in this application example is a browsing method set at the time of setting the screen saver without operation of the subscriber in step S1 of the flowchart shown in FIG. 6, for example, only new, only within a predetermined date, only unread. , Without limitation, fetching is started from the first mail magazine. (Setting Operation) In FIG. 8A, when the subscriber starts the screen saver setting program on the screen of the terminal 40, a display screen saver setting screen (not shown) including a display selection screen for selecting the content to be displayed on the screen is displayed. It is displayed (step U1).

Next, the subscriber selects the display selection screen of the screen saver setting screen, and the display contents displayed on the display selection screen, for example, graphic patterns, images, patterns, moving images,.
If "E-mail magazine" is selected from the mail magazine (step U2), and the browsing method (only new, only within a predetermined date, only unread, without restriction, ...) is selected (step U3), the e-mail magazine is selected. The display setting flag and the browsing method code are turned on (step U4). (Screen Save Operation) In FIG. 8B, if the operation of the terminal 40 is not performed for a predetermined time or more, the screen saver program starts (step V1), the screen saver setting content is determined (step V2), and the mail magazine display setting is changed. If so, the e-mail magazine browsing program is activated (step V3), and the e-mail magazine is dynamically displayed in the browsing method set based on the browsing method code (step V4).

With the above configuration, if the e-mail magazine display is set in the screen saver, the e-mail magazine whose contents are restricted by the display restriction method set by the subscriber is screen-save-displayed, so that the e-mail magazine can be browsed. The e-mail program does not need to be started in the future, and the subscriber can view only the necessary e-mail newsletters and the necessary parts in the e-mail newsletters using the set browsing method (new only,
Only within a predetermined date, only unread, without limitation, can be read in. In other words, it is not necessary to read unnecessary parts, so it is not possible to read all of the growing e-mail newsletters, which prevents the discarding of necessary topics and information hidden in unread e-mail newsletters. Yes, you can use the e-mail magazine effectively.

2-2. Operation Example FIG. 11 is a flowchart illustrating an operation example of the subscriber terminal and the distribution device. FIG. 11A is a flowchart illustrating an operation example of transmission restriction information transmission from the subscriber terminal to the distribution device. b) is a flowchart illustrating an operation example at the time of mail magazine distribution of the distribution device based on the transmission restriction information.

Step W1: (Generation of Transmission Restriction Information by Subscriber) In FIG. 11A, the user of the terminal 40, that is, the subscriber, generates transmission restriction information at the time of subscribing to the mail magazine or at any time after the subscription. The program 442 'is started, and the transmission restriction information generating means 71 generates the transmission restriction information 60'. The operation of generating the transmission restriction information in this step is the same as the operation in steps T5 to T10 in FIG.
(However, the display restriction information 60 is replaced with the transmission restriction information 60 '. Further, the storage operation in step T10 is not performed.)

Step W2: (Transmission of Subscriber Transmission Restriction Information) The transmission means 72 sends the transmission restriction information 60 'generated in step W1 to the distribution device of the URL stored in the mail magazine identification information column 62. It transmits via the Internet 20.

Step W3: (Reception of Transmission Restriction Information) When the transmission restriction information 60 'is transmitted from the terminal 40 to the distribution device 30, the transmission restriction information receiving means 83 receives the transmission restriction information 60'.

Step W4: (Storage of Transmission Restriction Information) The transmission restriction information storage means 84 stores the transmission restriction information 60 'received at step W3 in the storage storage memory 34 with the subscriber identification information attached thereto. ). Further, when the transmission restriction information is transmitted from the same terminal at different times, the storage content is updated with the transmission restriction information later.

With the above configuration, when transmission restriction information is sent from the subscriber terminal to the distribution device 30, the transmission restriction information is registered for each subscriber, so that the transmission restriction of the contents of the mail magazine is restricted at the time of distribution. As shown in FIG. 11B, a mail magazine whose transmission is restricted can be delivered to the terminal of a desired subscriber. Accordingly, since the terminal 40 does not receive an unnecessary e-mail magazine or article, the subscriber does not need to skip unnecessary parts. Step X1: (determine whether or not the subscriber has transmitted the transmission restriction information) In FIG. 11B, at the time of distribution of the e-mail magazine, the transmission restricting unit 85 checks whether or not the subscriber of the distribution destination is a subscriber who has registered the transmission restriction information in the distribution device. In this case, the state transits to X2; otherwise, the state transits to X3.

Step X2: (Transmission Restriction) The transmission restriction means 85 restricts the transmission of the mail magazine to be distributed this time for each subscriber based on the transmission restriction information of the subscriber, and transits to X3. The transmission restriction operation in this step is the same as the operation in steps S3 to S9 in FIG. 6A (however, “display restriction” is read as “transmission restriction”).

Step X3: (Distribution) The mail magazine distribution means distributes the result of the transmission restriction in step X2 to the terminal of the subscriber who has registered the transmission restriction information, and subscribes without registering the transmission restriction information. The full text of the e-mail magazine to be transmitted this time is distributed to the terminal of the user. The operations of X1 to X3 are repeated until the mail magazine is distributed to all the subscribers.

In the present embodiment, if the transmission restriction information is sent to the distribution device, only the portion including the article of interest in the distributed mail magazine can be easily browsed.
The actual reading rate of the e-mail magazine can be improved, and the effective use of the e-mail magazine can be realized.

The mail magazine distribution terminal 30 creates a mail magazine. At this time, a headline as shown by reference numerals 301 to 304 is added, and a mail magazine in which a delimiter 305 is added as a delimiter between topics and information in the mail body. To be created.

Here, the symbols [301 to 304]
] Is a symbol indicating that the characters are classified by the character string in [], and A to D in [] are layer symbols indicating the layers between the classes (A>B>C> D in this embodiment). And the symbol is the same when the symbol is the same (hierarchical symbol is not limited to alphabetic characters. It may be a number or kana. Also, without using the hierarchical symbol, [], “”, <>, ｛
(The symbol of｝ may mean a hierarchy.) [A:] to [C:
The character string in the brackets] is usually a character string indicating classification, but may not be based on a common standard for each e-mail magazine (that is, the classification standard may be different for each e-mail magazine issuer). A predetermined code (Japanese industrial classification code) may be used instead of the character string in []. Further, [D: 304 in FIG.
The character string in [] indicates the type of sentence in the e-mail magazine.

Also, the code 305 (delimiter) is [D:
In the text, the preceding delimiter (or [D:
]) And a topic or information separated by the following delimiter, if there is a character string corresponding to the registered extraction condition, as described later, the topic or information delimited by these delimiters is sent to the mail. At the time of browsing the magazine, it is extracted as a topic or information corresponding to the extraction condition (In the example of FIG. 15, information 1, information 2,..., Information n in the text are separated by a delimiter 305. Assuming that "battery" is the extraction condition, information 3 is extracted). In the example of FIG. 15, the delimiter 305 is a double punctuation mark (.), But the present invention is not limited to this.

In the example of FIG. 15, the hierarchy is defined by the type of the symbol. However, the present invention is not limited to this.

05 is a heading, and reference numeral 406 is a blank line (one or more lines) provided to indicate a delimitation (range) of a specific topic or information.
It is.

When creating a mail magazine on the terminal 30,
A heading 40 for classification is added to a line 412 next to the header information 411.
1 to 403, and if there is an abstract, a headline 404 for "abstract" is newly added to the line, and a headline 405 for "body" is added before the start line of the mail body. An e-mail magazine with one or more blank lines provided to separate topics and information in the text is created. Here, in the case of the heading of the same row, the heading on the right side has the highest hierarchy in the case of the heading of the same row, and the relation of the row is higher in the preceding row than in the following row.

The character strings denoted by reference numerals 401 to 403 usually use characters indicating classification, but may not be based on a common standard for each e-mail magazine (that is, the classification standard is different for each e-mail magazine issuer). May be different). Note that a predetermined code (Japanese industrial classification code) may be used instead of the character string. Also, 1
If there are more than one blank line 406 in the body, a character string corresponding to the extraction condition registered in the topic or information separated by the previous blank line (or the character string “body”) and the next blank line If there is, the topics or information separated by these blank lines are extracted as topics or information corresponding to the viewing conditions when browsing the e-mail magazine, as in the case of the delimiter 305 in FIG.

Step Q1: (Activation of E-mail Magazine Browsing Program) In FIG. 19, when the subscriber opens a desired e-mail magazine, the control unit 42 activates the e-mail magazine browsing program 443, and controls the e-mail program 441 to control the e-mail magazine. Move to browsing program 443. Hereinafter, under the control of the execution of the mail magazine viewing program 443 by the control unit 42, the terminal 40 performs the operations shown in the following steps Q2 to Q15.

Step Q2: (Refer to browsing condition registration table (judgment of presence / absence of classification condition)) The control unit 42 searches the browsing condition registration table 500, and the contents of the URL column 501 in each record of the browsing condition registration table 500 are A record that matches the URL of the mail magazine to be browsed is extracted, and the classification condition columns 502 to 504 are retrieved.
It is checked whether or not the classification condition is stored in any of the classification condition columns 502 to 504. If the classification condition is stored in any of the classification condition columns 502 to 504, the process transits to Q3. Otherwise, the process transits to Q5.

Step Q3: (Extraction of Classification Conditions) The control unit 42 extracts the classification conditions stored in the classification condition columns 502 to 504 from the record searched in step Q2. Note that one or two of the classification conditions A, B, and C may be spaces.

Step Q4: (E-mail Magazine Search by Classification Condition) The control unit 42 searches the mail magazine (data) to be browsed using the classification condition extracted in step Q3 as a key, and searches for a page (a plurality of pages) matching the classification condition. ) And the page data is stored in the temporary storage memory 43.

In the embodiment, the search key =
Classification condition A + classification condition B extracted in step Q3
+ In addition to the classification condition C, in the case of the notation shown in FIG. 15, [A: a], [B: b],
The character strings a, b, and c in [C: c] are taken out and a + b +
c, and the search key is compared with the classification condition A + the classification condition B + the classification condition C, but the comparison method is not limited to this. Similarly, in the case of the notation shown in FIG. 16, the character strings a, b, and c on the next line of the header information are extracted from the mail magazine and set as a + b + c, and the search key is compared with the classification condition A + the classification condition B + the classification condition C. However, the comparison method is not limited to this.

Step Q5: (Determination of Existence of Abstract Display) The control unit 42 examines the contents of the abstract display field 505 of the record searched in step Q2, and displays the abstract (=).
If “1”), the process transits to Q6; otherwise, Q7
Transitions to.

Step Q6: (Abstract display) The control unit 42 searches the page data to be browsed obtained in the above step Q4 for a heading indicating an abstract, extracts information in a predetermined range following the heading as an abstract, and temporarily extracts the information. The information is stored in the storage memory 43 and displayed on the display unit 45 together with the header information 801 and the classification 802 as shown in FIG.
Also, a text display button 805 on the abstract display screen 800,
A scroll button 806 and an end button 807 are displayed. The range to be extracted as the abstract 803 is shown in FIG.
In the e-mail magazine created by the notation of the example of FIG.
In the e-mail magazine created by the notation of the example, the heading of the abstract “abstract” to the blank line 406-0. When there are a plurality of abstract headings, a plurality of abstracts 803-1,
803-2, etc. are displayed.

Step Q7: (Operation Judgment) The subscriber looks at the abstract 803, clicks the text display button 805 with the mouse or the like when the user wants to browse the text, and clicks the end button 807 when the browsing is finished. click. The control unit 42 checks which button has been clicked, and if the body display button 805 has been clicked, Q8
When the end button 807 is clicked, the browsing of the e-mail magazine to be browsed is completed.

Step Q8: (Refer to browsing condition registration table (judgment of presence / absence of extraction condition)) The control section 42 adds 1 to the value i of the counter C, and then registers the extraction condition registration field 50 of the record searched in step Q2.
6-i is checked to determine whether or not the extraction condition is stored. If the extraction condition is stored in the extraction condition registration column 506-1, the flow goes to Q9; otherwise, the flow goes to Q14.

Step Q9: (Fetching of First Extraction Condition) The control unit 42 sets the value of the counter C to i = 1 and sets the extraction condition registration column 506-i (that is, the extraction condition registration column 506-1).
Extract the extraction condition (character string) stored in.

Step Q10: (E-mail magazine search by extraction condition) The control unit 42 searches the page data to be browsed obtained in step Q4 using the extraction condition extracted in step Q9 as a key.

Step Q11: (Extraction and Display of Extracted News) Information in a predetermined range including a character string that matches the extraction condition in the search in step Q10 is extracted as news (= specific topic,

FIG. 23 is a diagram showing an embodiment of a browsing condition registration screen superimposed on the mail magazine display screen (window display) when browsing the mail magazine, and FIG. 24 is a diagram showing a classification condition of the terminal 40 by the browsing condition registration program. 9 is a flowchart showing an example of a registration operation of a viewing condition and a viewing condition.

Step Y1: (Activation of browsing condition registration program) Step Q12 or Q14 in the flowchart of FIG.
When the subscriber clicks the condition registration button in FIG.
Then, the control unit 42 saves and holds the current value of the program counter, activates the browsing condition registration program 442 ″ and the e-mail magazine browsing program 443, and changes the control from the e-mail magazine browsing program 443 to the browsing condition registration program 442 ″. Move. Hereinafter, under the control of the execution of the viewing condition registration program 442 ″ by the control unit 42, the terminal 40 performs the operations shown in the following steps Y2 to Y11.

Step Y2: (Registration Screen Display) The control unit 42 superimposes (displays a window) the classification condition and browsing condition registration / update screen 1100 as shown in FIG. 23 on the mail magazine displayed on the display unit 45. .

Step Y3: (Retention of URL, etc.) The control unit 42 acquires the URL of the mail magazine currently displayed on the screen, retains the URL in the temporary storage memory 43, searches the browsing condition registration table 500, and UR
It is checked whether or not L is registered in the URL column 501.
If there is no record with the same URL (= at the time of new registration), the classification condition input column 1101, the abstract extraction availability selection column 1102, and the extraction condition input column 1103 are initialized to the initial value (in the embodiment, the classification condition input column 1101 is a space). , Abstract extraction availability column 1102 is not extracted (= “0”), extraction condition input column 1103 is invalid). Also, the same U
If there is an RL record (= when updating), the values stored in the record are extracted and displayed in the classification condition input field 1101, the abstraction possibility extraction 1102, and the extraction condition input field 1103.

Step Y4: (Input of classification condition, etc.) The cursor moves to the top of the classification condition input field 1101, so that the subscriber can input a desired classification name by referring to the classification of the displayed mail magazine. input. When the classification condition is not registered, the space key may be pressed. When the space key is pressed three times in succession, the cursor is moved to the abstract extraction availability selection column without inputting the classification name in any of the classification condition input columns 1101. When the key input to the classification condition input field 1101 is completed, the result of the key input (= the classification name (including the case of a space)) is held in the temporary memory 43.

Step Y5: (Selection of Abstract Extraction Availability) The subscriber selects one of the selection items in the abstract extraction availability selection column 1102, "(extract)" or "(extract) not," using a mouse or other selection means. Use to select. The control unit 42 sets “1” when “(extract)” is selected,
When “(extract)” is selected, “0” is held in the temporary memory 43.

Step Y6: (Input of Extraction Condition, etc.) The cursor moves to the top of the extraction condition input field 1103, so that the subscriber can refer to the displayed topic and information of the mail magazine and input a desired character string. Enter a key as an extraction condition. When the key input is completed, the result of the key input is stored in the temporary memory 43, and then the cursor is moved to the input field next to the extraction condition input field 1103. Up to five (not limited to) extraction conditions can be registered. When the fifth input is completed, the result of the key input is stored in the temporary memory 43, and then the cursor is input in the input confirmation column ("OK" column). 100
Move to 4. When the extraction condition is not registered, the space key may be pressed. When the space key is pressed five times in succession, a space is entered in any of the extraction condition input columns 1103, and the cursor is moved to the confirmation column 1104. In addition,
In the case of updating, the cursor may be moved to an input field that requires updating using the movement keys (→, ↓) and key input may be performed (when the key input is completed, the key input result is temporarily stored in the temporary memory 4).
The cursor moves to the next column after holding at 3).

Step Y9: (judgment of registration end) The control unit 42 operates the subscriber to end registration (screen close button 1
If 105 (click of “×”) is performed, it is not likely to transit to Y10, otherwise Y is used for the next condition registration / update.
Return control to 2.

Step Y10: (Registration end processing) The control unit 42 deletes the browsing condition registration / update screen 1100,
After clearing the character string and the like held in the temporary memory 43, the value of the saved program counter is returned to return to the state before starting the browsing condition registration program (step Q12 or Q14 in FIG. 19).

With the above configuration, it is possible to set the browsing conditions (classification conditions, availability of abstract display, extraction conditions) for browsing a new e-mail magazine. Further, even if the browsing conditions have already been set, the setting values can be updated (changed, added, or deleted) for each e-mail magazine. Therefore, a desired topic or article can be extracted under the set browsing conditions only by inserting a headline or a delimiter without unifying the contents of each mail magazine in a certain format.

In the above description of the flowchart of FIG. 19, an example is shown in which the operation of the condition registration button when displaying the mail magazine by the mail magazine browsing program 443 links to the browsing condition registration program 442 ".
