Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document display device for displaying a document over a plurality of pages, and in particular, it can selectively extract and display document data of an arbitrary page as if turning a page of a normal paper document. The present invention also relates to a document display device capable of displaying the document data of an arbitrary page of the document together with the document data of the rolled page.

[0002]

2. Description of the Related Art Conventionally, various document display devices for displaying a document over a plurality of pages have been proposed and used in various document processing devices.

A typical document display device of this type is one in which a desired page of a document is designated by key input and only the document data of the designated page is selectively displayed on the screen. ..

A relative page with respect to a display page such as a next page or a previous page is designated by pressing a dedicated next page key or a previous page key and displayed on the document data screen of the designated page.

In combination with the configuration of and
It enables both absolute page designation and relative page designation of display pages.

Are known.

By the way, in the conventional document display device of this type, if the page to be displayed is known in advance, the operation is easy. However, by intuitively grasping the amount of the entire document, this page of this document can be grasped. It is difficult to specify an analog display page such as wanting to display the document data of. However, at present, such a demand is quite large in an actual document display device.

Therefore, a display device in which a bar graphically represented is displayed at an appropriate position on the display screen, the bar is regarded as the whole document, and an arbitrary position of the bar is pointed by a pointing device or the like is conceivable. There is. In this case, the amount of the entire document can be intuitively grasped, and the request to display the document data of this page of the entire document can be answered, but a specific page known in advance can be displayed. It becomes very difficult to display selectively.

Further, in the conventional document display device, basically, only desired one page of document data is displayed on the screen, so that the displayed document data is compared with the document data of other pages. I can't.

Therefore, for example, a device that divides the screen into two and displays one document by dividing it into two, or another document display device is driven, and one document is displayed by two document display devices. Display devices have also been proposed.

Here, in a device for dividing a screen into two and displaying one document in two, a command for dividing the screen is input by a keyboard or pointing device, and the screen is displayed by the keyboard or pointing device. The operation of designating the position at which to divide is performed. Further, in a device which drives another document display device, a special operation for driving another document display device is required every time there is a request to compare with document data of another page.

However, such an operation is very troublesome, and the work efficiency of the partial comparison in the document is deteriorated.

[0013]

As described above, in the conventional document display device, it is possible to intuitively grasp the amount of the entire document and display the document data of the page around this document in an analog manner. Although it is difficult to specify a display page, and a document display device that allows the user to intuitively grasp the amount of the entire document and specify an analog display page has been considered, such a device is known in advance. It becomes difficult to selectively display a specific page. Further, the conventional document display device has a problem that a very troublesome operation is required when there is a request to compare the displayed document data with the document data of another page.

Therefore, according to the present invention, the document data of an arbitrary page can be selectively extracted and displayed by a very simple operation as if the page of a normal paper document is to be turned over. An object of the present invention is to provide a document display device capable of referring and comparing the document data of an arbitrary page of a document and the document data of a displayed page with a feeling of taking out an arbitrary page.

[0015]

In order to achieve the above object, the present invention relates to a document display device for displaying a document spanning a plurality of pages, in which windows corresponding to the pages of the document are partially shifted and sequentially arranged. Among the window display means for displaying in an overlapping manner and the window corresponding to each page of the document displayed by the window display means, the document data of the page corresponding to the window is displayed in the frontmost window, and another window is displayed. By designating a document display control means for displaying only the page number corresponding to the window in the shifted area in the window and an arbitrary window among the plurality of windows displayed by the window display means, A page display control means for displaying the designated window in the forefront is provided.

Further, according to the present invention, in a document display device for displaying a document spanning a plurality of pages, window display means for sequentially overlapping and displaying windows corresponding to respective pages of the document, and the window. The document data of the page corresponding to the window is displayed in the frontmost window among the windows corresponding to the respective pages of the document displayed by the display means, and the other window is displayed in the shifted area. A document display control means for displaying only the page number corresponding to the window and an arbitrary window of the plurality of windows displayed by the window display means are designated to display the designated window at another position. , Reference page display control means for displaying the document data of the page corresponding to the window in the window displayed at the other position Characterized by comprising a.

[0017]

With the window display means, a plurality of windows corresponding to respective pages of a document over a plurality of pages are sequentially overlapped with some of the windows shifted, and by the document display control means,
The document data of the page corresponding to the window is displayed in the frontmost window of the plurality of displayed windows, and only the page number corresponding to the window is displayed in the shifted area in other windows. Is displayed. Then, the page display control means displays any one of the plurality of windows by, for example, clicking the mouse to display the specified window at the front. As a result, the document data of an arbitrary page can be converted to a normal paper document by a very simple operation of, for example, designating an arbitrary window among a plurality of windows that are sequentially displayed in a pile by clicking the mouse. It becomes possible to selectively extract and display as if turning the page.

Further, the reference page display control means designates an arbitrary window among the plurality of windows displayed by the window display means by, for example, a drag operation of a mouse, so that the designated window is moved to another position. , And the document data of the page corresponding to the window is displayed in the window displayed at the other position. This makes it possible to perform reference comparison between the document data of the displayed page and the document data of an arbitrary page with a very simple operation of specifying an arbitrary window among a plurality of windows by, for example, dragging the mouse. Become.
