Further, the character string of the summary information has a larger number of characters than the character string of the title information and is smaller than the character string of the content article, and reflects the contents of the content article. The position information is information indicating a URL where the content exists.

  Therefore, a content article can be displayed based on title information, update information, summary information, and position information included in the content information. When an area corresponding to the article URL on the display panel 50 is pressed, the URL can be accessed by the Internet connection program 16b to browse the content article (content browsing function).

  Returning to FIG. The RAM 18 is a readable / writable volatile memory, and has a deletion flag 18a. The deletion flag 18a is a flag that is turned on when duplicate information is included in the currently acquired content information and the acquired content information and there is information to be deleted.

  The NVRAM 20 is a rewritable nonvolatile memory, and has an acquired article storage area 20a, a currently acquired article storage area 20b, and a URL storage area 20c. The acquired article storage area 20a is an area for storing already acquired content information. The acquired article storage area 20a has a predetermined storage capacity in advance, and when the storage capacity is exceeded, the stored order is sequentially deleted from the oldest. The currently acquired article storage area 20b is an area for temporarily storing content information included in the content composite information acquired this time. The content information stored in both storage areas 20a and 20b is stored in association with the URLs of the servers 90 and 91 so that the acquired content providing servers 90 and 91 can understand.

  In the present embodiment, the content information stored in both storage areas 20a and 20b is subjected to content update processing (see FIG. 2) every time new content composite information is acquired from the content providing servers 90 and 91. The information is configured to be updated. However, when the user operates the keypad 52, new content composite information is acquired from the content providing servers 90 and 91, and the content update process is executed. You may comprise.

  Further, the currently acquired article storage area 20b may be continuously stored until new content composite information is acquired, or may be configured to be deleted after a predetermined time has elapsed. When the content composite information is continuously stored, the user can always browse the latest content information, and the NVRAM 20 area can be used effectively when the content composite information is deleted after a predetermined time.

  In the URL storage area 20c, a URL indicating the acquisition destination of the content composite information (feed information) of the content providing servers 90 and 91 is stored. The URL stored in the URL storage area 20c can be set, for example, by the user using the keypad 52 on a site setting screen (not shown) displayed on the display panel 50.

  The display panel 50 is a display device that displays various information. The display area of the display panel 50 is a relatively narrow area. In the present embodiment, the display panel 50 is configured to have a size corresponding to the list of content articles shown in FIG.

The printing unit 54 has a printing mechanism such as an ink jet type or a laser type, and prints a generated print page on a print sheet, for example. The scanning unit 56 has a reading mechanism such as a CCD or CIS. The FAX unit 58 executes various operations for executing FAX communication. The network interface 60 is connected to the LAN line 4 so that the MFP 10 can access the Internet 8.

  Next, content update processing executed by the CPU 14 of the MFP 10 will be described with reference to FIG. In the present embodiment, the acquired content information includes each piece of information corresponding to the content article shown in FIG. 3A, and the content information acquired this time is the content article shown in FIG. It is assumed that each piece of information corresponding to is included.

  The content information will be described by exemplifying the content article having the item number “1” shown in FIG. 3A. Title information indicating a character string “Title of Nagoya” of the title, “2009/2/1” Update information indicating an update time of 10:00, summary information indicating a character string “It is a weather in Nagoya City, Aichi Prefecture”, and “http://www.tenki_rss.co.jp/aichi. and “location information indicating the position on the network 8”. The description of the content information about the content articles with the item numbers “2” to “4” shown in FIG. 3A and the content articles with the item numbers “a” to “d” shown in FIG. To do.

  Returning to FIG. The content update process is executed when new content composite information is acquired from the sites of the content providing servers 90 and 91. First, the content information included in the content composite information acquired from the content providing servers 90 and 91 is stored in the currently acquired article. Store in the area 20b (S1).

  When the content information is stored in the currently acquired article storage area 20b in the process of S1, one content information of the content information acquired this time and all the content information stored in the acquired article storage area 20a Are sequentially compared (S2).

  Specifically, the process of S2 includes the content information corresponding to one content article among the content articles of the item numbers “a” to “d” shown in FIG. 3B and the item shown in FIG. This is a process of comparing the content information corresponding to the content articles of numbers “1” to “4”, and the information corresponding to “article URL”, “title”, “summary”, and “publication date” is compared.

  In the process of S3, it is determined whether or not the comparison between the one piece of content information acquired this time and all the acquired content information is completed (S3). If the comparison is completed (S3: Yes), S14 If there is uncompared content information acquired (S3: No), the process proceeds to S4.

  In the process of S4, as a result of the comparison in the process of S2, whether or not there is the same position information in the acquired content information with respect to the position information of the one content information acquired this time, that is, “article URL "Is matched (S4).

  If the “article URL” matches in the process of S4 (S4: Yes), next, whether title information or summary information matches, that is, whether “title” or “summary” Is determined (S5), and if both the "title" and the "summary" do not match (S5: No), the process returns to the process of S2, and the one content information and the next acquired content Compare with information.

  Note that it is determined that the process of S5 is No, the position information of the content information (“article body URL”) matches, but the title information and the summary information (“title” and “summary”) do not match. Therefore, the possibility of the same or similar content information is reduced. Therefore, the process proceeds to S2 in order to compare with the next acquired content information.

  On the other hand, if either “title” or “summary” matches in the process of S5 (S5: Yes), in addition to the position information (“article URL”), title information or summary information (“title”) Or at least one of “summary”) matches, the possibility of the same content information (content article) increases. Therefore, in order to delete one of the pieces of content information, whether the update information is the latest content information acquired this time, that is, whether the “publication date” is the latest content information acquired this time is updated. Is determined (S6).

  If the content information acquired this time is the latest in the process of S6 (S6: Yes), deletion of all information of the content information stored in the acquired article storage area 20a is set and the deletion flag 18a is set. Is turned on (S7), and if the content information stored in the acquired article storage area 20a is the latest (S6: No), the deletion of all information of the content information acquired this time is set and the deletion flag 18a is set. Is turned on (S8), and the process proceeds to S2.

  Here, with reference to Fig.4 (a), the process of S7 and S8 is demonstrated. In FIG. 4A to FIG. 4C, the description “http: // www” of the article URL is abbreviated as “...”. As shown in FIG. 4 (a), for the content article title “Brother Industry Financial Results” of the item number “a” and the article URL “http://www.keizai_rss.ne.jp/brother — 01.htm” The title “2” matches the article URL. Since the content article acquired this time with the item number “a” is the latest, the deletion date and time is set to delete all information of the content information of the content article with the item number “2” (S7). processing).

  If the item number “2” is the latest, the deletion date is set to delete all information of the content information corresponding to the item number “a” (step S8). In FIG. 4A, the summaries are different character strings. However, even when the titles are different and the summaries match, deletion of one of the content information acquired this time or the content information already acquired according to the release date Is set.

  Returning to the processing of S4 in FIG. If it is determined in the process of S4 that the “article URL” between the one piece of content information acquired this time and the acquired content information do not match (S4: No), the position information (“main body URL”) is different. Although the possibility of completely different content information is high, in order to determine the degree of matching, it is determined whether or not the summary information matches, that is, whether or not the “summary” matches (S9), and the title information is It is determined whether or not they match, that is, whether or not the “title” matches (S10).

  If the “summary” does not match (S9: No), the position information and the summary information (“article URL” and “summary”) are different, so it is determined that the content information (content article) is completely different, and S2 Move on to processing. The processing of S9 is No in the case of the content article with the item number “b”, and as shown in FIGS. 3A and 3B, the articles with the item numbers “1” to “4”. The URL and summary do not match.

  Further, if the “summary” and the “title” match (S9: Yes, S10: Yes), the position information (“article URL”) is different, but the title information and the summary information (“title” and “summary”) are different. ) Match, it can be determined that there is a high possibility of the same or similar content information (content article), and deletion other than the position information of the content information acquired this time is set and the deletion flag 18a is turned on (S11) , The process proceeds to S2.

  If it is determined that the “summary” matches but the “title” does not match (S9: Yes, S10: No), next, whether or not the update information matches, that is, “publication date”. (S12: No), only the summary information (“summary”) matches, and the same or similar content information ( Since there is a low possibility that it is a content article), the process proceeds to the process of S2, and if the “release date” matches (S12: Yes), there is a possibility of similar content information (content article). Deletion other than the title information and position information of the acquired content information is set and the deletion flag 18a is turned on (S13), and the process proceeds to S2.

  Here, with reference to FIG. 4B and FIG. 4C, the processing of S11 and S13 will be described. As shown in FIG. 4B, the article URL “http://www.green_rss.ne.jp/foot.htm” of the content article of item number “c” and the summary “Today, a futsal tournament is held in Mizuho Ward. The summary of the item number “3” and the release date coincide with the release date “2009/1/1 10:00”. That is, although the article URLs are different, since the summary and the publication date are the same, the article URL of the item number “c” and the information corresponding to the title are associated with the content information of the item number “3” to store the acquired article It is stored in the area 20a, and deletion of all other information is set (processing of S11).

  As shown in FIG. 4 (c), the article URL “http://www.tenki_rss.ne.jp/nagoya.htm” of the content article of the item number “d” and the summary “Weather in Nagoya, Aichi Prefecture.” And the summary and title of the item number “1” match the title “Nagoya weather”. That is, although the article URLs are different, the summary and the title match, so the position information corresponding to the article URL of the item number “d” is associated with the content information of the item number “1” and stored in the acquired article storage area 20a. All other information deletion is set (processing of S13).

  Note that the content article with the item number “d” has the same summary as the article URL of the content article with the item number “4”, and the publication date is the latest with the item number “d”. Therefore, it is necessary to leave the content article acquired this time. That is, the content information that has been determined to be the same as the content information that has been acquired this time and content information that has been determined to be similar are included in the acquired content information.

  The processing after S14 will be described. When the process of S3 is Yes, since the comparison between one piece of content information and all acquired content information is completed, it is determined whether or not the deletion flag 18a is turned on in the comparison result (S14). If the deletion flag 18a is turned on (S14: Yes), the information set for deletion in the processing of S7, S8, S11, S13 is deleted and the information in the acquired article storage area 20a is updated (S15). , The process proceeds to S16.

  On the other hand, if the deletion flag 18a is off in the process of S14 (S14: No), there is no need to delete each piece of information included in the content information. It is determined whether the content information is compared with the acquired content information (S16).

  If it is determined in the process of S16 that all comparisons have been completed (S16: Yes), this content update process is terminated, and if the comparison of the content information acquired this time has not been completed (S16: No), in order to compare the next one of the content information acquired this time with the acquired content information, the process proceeds to S2.

  Next, an example displayed on the display panel 50 based on the content information updated by the content update process will be described with reference to FIG. The display shown in FIG. 3C is displayed when an overlap (not shown) of the keypad 52 is operated by the user.

  As shown in FIG. 3C, the content article with the item number “1” is different from the content article with the item number “d” acquired this time, but the summary and title match. The article URL of item number “d” should be displayed in association with it, but the content article of item number “d” is not displayed because it is displayed as the content article of item number “4”.

  The content article with the item number “2” is determined to be the same as the content article with the item number “a” acquired this time, and the item number “a” has the latest release date, so the content article “a” is changed to the content article “a”. Has been updated.

  The content article with item number “3” is displayed as it is because there is no identical content article acquired this time, but the summary and publication date of the content article with item number “c” match. In the lower part of the content article of item number “3”, the content article of item number “c” is displayed as a similar content article. In the lower display of the item number “3”, the update information and summary information (publication date and summary) of the content article of the item number “c” are deleted, so the update information and the summary of the item number “3” are deleted. Information is displayed using information, and the information is displayed in bold letters so that the user can recognize that fact. Therefore, the user can easily recognize that the content article in the lower row of the item number “3” is determined to be similar and some information has been deleted, and the content article from which some information has been deleted. If the user wants to browse the content article, the user can browse the content article by pressing the corresponding article URL. Of course, if the user confirms the content article and is exactly the same, it can be deleted by the user's operation.

  The content article with the item number “4” is determined to be the same as the content article with the item number “d”, but the content article with the item number “d” is the latest, so the content article with the item number “d” Has been changed. The content article with the item number “5” is the content article with the item number “b”, and since it is determined that there is no identical or similar to the item numbers “1” to “4”, it is added as the item number “5”. Is displayed.

  As described above, in the content update process, when it is determined that the content information acquired this time from the content providing servers 90 and 91 and the acquired content information stored in the acquired article storage area 20a are the same. Since the content information with the older update date and time is deleted, it is possible to suppress the storage of duplicate content information in the acquired article storage area 20a. As a result, the maximum content information can be stored in the acquired article storage area 20a, so that many types of content articles can be stored and the content browsing function can be used effectively. Further, since the content articles displayed on the display panel 50 are not displayed in duplicate, the display area of the display panel 50 can be used effectively.

  Further, the position information (“article URL”) of the content information matches, but the title information and the summary information (“title” and “summary”) do not match, and the same or similar content information (content article). If the possibility is low, the content information is not deleted. Therefore, it is possible to prevent the content information from being deleted more than necessary and preventing the user from browsing.

  If the title information and the summary information (“title” and “summary”) match, although the location information of the content information (“article URL”) is different, only the location information is left and other information is deleted. If the summary information and the update information (“summary” and “update date and time”) match, the content information stored in the acquired article storage area 20a is deleted because the other information is deleted leaving the position information and the title information. The duplication of information can be suppressed and the amount of information can be minimized. Furthermore, since at least the position information is stored, the content article deleted based on the position information can be acquired again, and the user can be prevented from browsing the content article.

  In addition, when a part of the content information is deleted in the list of content articles displayed on the display panel 51, the display is performed using information included in the content information associated with the deleted content information. Therefore, it is possible to display content articles that are considered to be the same or similar, while effectively using the storage area of the acquired article storage area 20a. Furthermore, since the display mode is displayed differently from other content articles, it is possible to easily recognize a deleted content article that may be the same or similar.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  In the above embodiment, two content providing servers 90 and 91 connected to the MFP 10 are provided, but three or more content providing servers may be connected, and content can be provided by a movable PC or mobile phone. It may be configured as follows.

  Further, in the above-described embodiment, the position information (“article URL”) among the information included in the content information is used as a reference, and whether or not the title information and the summary information match is determined based on whether or not the position information matches. In addition, it is configured to first determine whether the summary information of the title information and the summary information matches. That is, priority is given to the information included in the content information, but the information with high priority may be title information or summary information instead of position information, and the priority can be set as appropriate. . Further, the number of pieces of information to be deleted may be changed according to the number of matched information regardless of the priority included in the content information. For example, a larger number of information including all information is deleted as the number of matching information is larger, and a smaller number of information is deleted as the number of matching information is smaller.

  Further, in the above embodiment, when it is determined that the content information acquired this time and the acquired content information are the same, all the information with the oldest release date is deleted, and the latest content article is always displayed. Although it is configured to be browseable, it may be configured to delete all information with the latest release date. In this configuration, if the content article is automatically deleted after a predetermined time has elapsed after being stored in the acquired article storage area 20a, the content information in the acquired article storage area 20a is likely to be deleted. The storage area can be used effectively.

  In the above-described embodiment, the content information acquired this time and the acquired content information are the same, and even when deletion of one of the content information is set, the content information acquired this time and the other acquisition information In order to determine the similarity to the already acquired content information, it is configured to perform comparison with all the acquired content information. However, when deletion of any one of the content information is set, You may comprise so that a comparison with the acquired content information may not be performed. With this configuration, it is possible to reduce the control burden of content update processing, and in particular, the greater the number of pieces of acquired content information, the more effective the control burden can be reduced.
