1. A Web page viewing apparatus comprising:

an image information storing unit for storing image information of a Web page viewed online from a Web server;

a page to be displayed selecting unit that selects a page of a Web page image that a viewer desires to view; and

a first comparing unit that, when image information corresponding to the selected page is stored in the image information storing unit, displays the image information corresponding to the selected page.

2. The Web page viewing apparatus according to claim 1,

wherein the image information storing unit stores image information of the selected page and data on a date of update for the image information of the selected page on the Web page

and wherein the first comparing unit, at the time of viewing the Web page, when the image information corresponding to the selected page is stored in the image information storing unit, compares a date of update for the image information stored in the image information storing unit with a date of update for the image information corresponding to the selected page in the Web server,

and when the image information corresponding to the selected page in the Web server is newer, reads the newer image information corresponding to the selected page from the Web server, and updates the image information of the selected page stored in the image information storing unit to the newer image information.

3. The Web page viewing apparatus according to claim 1, further comprising a table of contents information storing unit for storing a table of contents data on the Web page and data on a date of update for the table of contents data on the Web page,

wherein the first comparing unit, at the time of viewing the Web page, compares a date of update for the table of contents data stored in the table of contents information storing unit with a date of update for table of contents data in the Web server,

and when the table of contents data in the Web server is newer, reads the table of contents data in the Web server

and updates the table of contents data stored in the table of contents information storing unit to the read table of contents data.

4. The Web page viewing apparatus according to claim 2, further comprising a table of contents information storing unit for storing a table of contents data on the Web page and data on a date of update for the table of contents data on the Web page,

wherein the first comparing unit, at the time of viewing the Web page, compares a date of update for the table of contents data stored in the table of contents information storing unit with a date of update for table of contents data in the Web server,

and when the table of contents data in the Web server is newer, reads the table of contents data in the Web server

and updates the table of contents data stored in the table of contents information storing unit to the read table of contents data.

5.
