Abstract

A hypertext displaying apparatus is provided. When a link destination indicated in stored data is designated, a processing section instructs a transmission/reception section to download hypertext data at the link destination, and instructs a history storage section to register an identifier of the currently-displayed stored data. If a user gives a “previous content” instruction, the processing section reads from a stored information storage section the stored data corresponding to the identifier registered in the history information storage section, so that the stored data is displayed on a screen.

Claims

1. A hypertext displaying apparatus for downloading hypertext data via a network, and displaying a content represented by the hypertext data, comprising:

a download section operable to download, when a link destination is selected, hypertext data at the selected link destination, and store the downloaded hypertext data in a temporary storage section;

a stored data storage section operable to store hypertext data selected from among the hypertext data having been downloaded and stored in the temporary storage section by the download section;

a list display section operable to display a list of stored data in the stored data storage section;

a select section operable to select a stored data from the list displayed by the list display section;

a display section operable to display a content represented by hypertext data newly downloaded by the download section, or display a content represented by the stored data selected by the select section;

a displaying history storage section operable to store, as a displaying history, an order in which at least one content represented by hypertext data newly downloaded by the download section is displayed by the display section; and

a redisplaying order control section operable to control, in accordance with the displaying history stored in the displaying history storage section, an order in which the contents are redisplayed by the display section, wherein

when a content represented by a first stored data in the stored data storage section is displayed, and a link destination indicated within the content represented by the first stored data is selected, the displaying history storage section adds the content represented by the first stored data to the displaying history, and

when a content at the selected link destination is displayed, and an instruction for displaying a content preceding the content at the selected link destination is issued, the redisplaying order control section allows contents to be redisplayed by the display section in a sequential manner in accordance with an order of the displaying history, going back, at least to the content represented by the first stored data.

2. The hypertext displaying apparatus according to claim 1, wherein the list display section displays a list of titles of the stored data in the stored data storage section.

3. The hypertext displaying apparatus according to claim 2, wherein the stored data storage section stores an acquisition source address indicating an address of the hypertext data on the network.

4. The hypertext displaying apparatus according to claim 3, wherein

when the content represented by the first stored data in the stored data storage section is displayed, and a content represented by a second stored data in the stored data storage section is displayed next, and a link destination indicated within the content represented by the second stored data is selected, the displaying history storage section adds the content represented by the second stored data to the displaying history without adding the content represented by the first stored data to the displaying history, and

when a content at the selected link destination is displayed, and an instruction for displaying a content preceding the content at the selected link destination is issued, the redisplaying order control section allows contents to be redisplayed by the display section in a sequential manner in accordance with an order of the displaying history, going back, at least to the content represented by the second stored data.

5. The hypertext displaying apparatus according to claim 3, further comprising stored data deletion section operable to delete stored data in the stored data storage section, wherein

when the first stored data to be redisplayed has been deleted by the stored data deletion section, the download section newly downloads hypertext data by using the acquisition source address stored in the stored data storage section, and

the display section displays a content represented by the newly downloaded hypertext data.

6. A hypertext displaying method for downloading hypertext data via a network, and displaying a content represented by the hypertext data, the hypertext displaying method comprising:

downloading, when a link destination is selected, hypertext data at the selected link destination, and storing the downloaded hypertext data in a temporary storage section;

storing, in a stored data storage section, hypertext data selected from among the hypertext data having been downloaded and stored in the temporary storage section in said downloading of the hypertext data;

displaying a list of stored data in the stored data storage section;

selecting a stored data from the list displayed in said displaying of the list;

displaying a content represented by hypertext data newly downloaded in said downloading of the hypertext data, or displaying a content represented by the stored data selected in said selecting;

storing, as a displaying history, an order in which at least one content represented by hypertext data newly downloaded in said downloading of the hypertext data is displayed in said displaying of the content; and

controlling, in accordance with the displaying history stored in said storing of the displaying history, an order in which the contents are redisplayed by the display section, wherein

when a content represented by a first stored data in the stored data storage section is displayed, and a link destination indicated within the content represented by the first stored data is selected, said storing of the displaying history adds the content represented by the first stored data to the displaying history, and

when a content at the selected link destination is displayed, and an instruction for displaying a content preceding the content at the selected link destination is issued, said controlling of the order in which contents are redisplayed allows contents to be redisplayed in said displaying of the content in a sequential manner in accordance with an order of the displaying history, going back, at least to the content represented by the first stored data.

7. The hypertext displaying method according to claim 6, wherein said displaying of the list displays a list of titles of the stored data in the stored data storage section.

8. The hypertext displaying method according to claim 7, wherein the stored data storage section stores an acquisition source address indicating an address of the hypertext data on the network.

9. The hypertext displaying method according to claim 8, wherein

when the content represented by the first stored data in the stored data storage section is displayed, and a content represented by a second stored data in the stored data storage section is displayed next, and a link destination indicated within the content represented by the second stored data is selected, said storing of the displaying history adds the content represented by the second stored data to the displaying history without adding the content represented by the first stored data to the displaying history, and

when a content at the selected link destination is displayed, and an instruction for displaying a content preceding the content at the selected link destination is issued, said controlling of the order in which contents are redisplayed allows contents to be redisplayed in said displaying of the content in a sequential manner in accordance with an order of the displaying history, going back, at least to the content represented by the second stored data.

10. The hypertext displaying method according to claim 8, further comprising deleting stored data in the stored data storage section, wherein

when the first stored data to be redisplayed has been deleted by said deleting of the stored data, said downloading of the hypertext data newly downloads hypertext data by using the acquisition source address stored in the stored data storage section, and

said displaying of the content displays a content represented by the newly downloaded hypertext data.
