Abstract
Abstract A document display apparatus of the invention displays a document containing a plurality of pages in such a manner that one page lies on top of another, allowing easy and intuitive identification of the first page of the document. When a page turning command is entered through an input device, a designator specifies a page which should become the first page of the document based on page layering sequence information stored in a page data table memory and a page location calculator calculates new display locations of the individual pages so that pages to be shown behind a current page (or the page in the topmost layer) are successively displaced from the current page by an amount determined by preset page offset values (ΔX, ΔY) except for the first page of which amount of displacement is increased by an additional page offset value (+α) in both the horizontal and vertical directions. An updating device updates information stored in the page data table memory in accordance with the newly calculated display locations and a display processor produces on-screen images of the individual pages based on the information stored in the page data table memory.

Claim 1
Independent Claim
222 words
A document display apparatus for displaying a document containing a plurality of pages on a screen in such a manner that one page lies on top of another with successive displacements, said apparatus comprising: an input device for entering page turning commands; a page data table memory for storing information on a layering sequence and display locations of the individual pages as well as a selection of a page which should currently be shown in a topmost layer; a designator for specifying a page which should become the first page of the document based on the layering sequence information stored in said page data table memory; a page location calculator for calculating new display locations of the individual pages when a page turning command is entered so that pages to be shown in other than the topmost layer are arranged with a preset amount of successive displacements from the page to be shown in the topmost layer except for the first page which is displaced by a larger amount than the other pages; an updating device for updating the information stored in said page data table memory in accordance with the page turning command and newly calculated display locations; and a display processor for producing on-screen images of the individual pages based on the information stored in said page data table memory.
