Abstract

PROBLEM TO BE SOLVED: To execute scrolling straight without permitting a document part being generated to be fluctuated right and left when a document with two facing pages respectively having different margins is displayed by vertically arranging them in a line at every page so as to be scrolled in a document processor where the document of a computer and a word processor, etc., is generated and printing-outputted while being displayed on a screen. SOLUTION: The document is generated by an input device 1 such as a keyboard and a mouse, etc., while viewing the screen of a display device 4 and printed and outputted by an output device 6. At this time, when the document with the two facing pages respectively having different margins is scrolled by vertically arranging them at every page, the positions of printing sheet of paper in right and left directions is controlled by a central arithmetic processor 2 so as to align the centers of the respective document parts of the right and left pages in the right and left directions in the display screen.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a computer and a word processor, and more particularly to a document processing apparatus having an improved display method when a document is created.

[0002]

2. Description of the Related Art In a document processing apparatus such as a computer or a word processor, a document is usually created while being displayed on a monitor. When a document is actually created, a document such as a keyboard or a mouse is displayed on a display screen. It is configured to be created using a simple input device. At that time, the ease of use of the document creation device differs depending on where the input character string (sentence) is arranged on the display screen of the entire document, that is, how the page arrangement at the time of printing is set. Come.

[0003] When printed as viewed on a display screen,
The upper and lower and left and right parts where the text is not displayed or described are called margins. Usually, in addition to the method of displaying all pages on the screen with the margins set in the same way, the right and left of the odd and even pages are displayed. There is a method of setting the length of the left and right margins to different values and displaying the facing pages. Further, there is a method of displaying the images on the same display screen, or using a method of arranging each page in a vertical line and moving the screen so as to display one page at a time (called scrolling).

[0004]

However, in the conventional document processing apparatus as described above, there are the following problems when the above-mentioned double-page spread is simultaneously displayed.

[0005] That is, if an odd-numbered page and an even-numbered page are displayed at the same time in a two-page spread document, the display portion becomes horizontally long and extends off the screen, or when the size is fitted, the characters become small. May be difficult to see and difficult to use.

In the case where double-page spreads having different left and right margins, such as binding margins, are displayed on a page-by-page basis, as shown in FIG. In addition, as shown in FIG. 7, page a and page b are not displayed at the same position in the left and right direction on the display screen, resulting in left and right displacement. It feels like it is hard to use.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In a case where a document of a double-page spread having different left and right margins is used by scrolling one page at a time in a line. It is an object of the present invention to provide a document processing apparatus which allows a user to easily create a document by making it possible to scroll a document being created straight without being swung right and left.

It is another object of the present invention to provide a document processing apparatus which can be easily used by allowing only a document creation section to display when a sheet size is larger than a display screen when scrolling.

[0009]

SUMMARY OF THE INVENTION A document processing apparatus according to the present invention is a document processing apparatus that creates and prints out a document while displaying the document on a screen. When scrolling by displaying each page vertically in a line, control means for controlling the position of the printing paper in the left-right direction such that the center of each document portion of the left and right pages in the left-right direction is aligned on the display screen. It is provided.

Further, in the above-mentioned apparatus, the size of the display screen is set to be the same as or slightly larger than the size of the document display section.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the document processing apparatus according to the present invention.

In FIG. 1, 1 is an input device such as a keyboard and a mouse, 2 is a central processing unit (control means) for controlling the entire document processing apparatus, and 3 is a control program executed by the central processing unit 2. Storage device for storing data such as document information, margins, print information, etc., 6 is a printer, and 6 is a printer. And the like for performing print output.

The above-described apparatus creates and prints out a document while displaying the document on a screen by the display device 4.
When scrolling (scrolling) by displaying two pages of spread pages with different margins on the left and right pages in a vertical line for each page, the center of each document part of the left and right pages in the left and right direction is on the display screen. The central processing unit 2 controls the horizontal position of the printing paper.

That is, a document in the form of a two-page spread is set to 1
When scrolling vertically in a line for each page, the position of the printing paper is moved so that the document section being created can be scrolled straight without swinging left and right.

Further, by making the size of the display screen the same as or slightly larger than that of the document display section, unnecessary portions are not displayed even if the display screen is scrolled when the paper size is larger than the size of the display screen. ing.

FIG. 2 shows the relationship between the document layout and the display screen in this embodiment, and FIG. 3 shows the positional relationship between the document layout and the paper size.

As shown in FIG. 2, the setting is performed so that the document portions are arranged vertically in the same horizontal range. The display screen is smaller than the screen size of the display device 4 and can be scrolled vertically. The size of the display screen is set as described above.

As shown in FIG. 3, when a page a and a page b (a + 1) are present and a part of both pages are displayed, the binding margin is the right margin of the page a and the binding margin of the page b. Left margin. In the case of a double-page spread where the left and right binding margins are different, the display screen size that has been initialized in advance and the document part size, which is the value obtained by subtracting the left and right binding margins, are set so that they are arranged vertically at the same position. The arithmetic processing is performed such that the centers of are aligned vertically.

At this time, if the display screen size is smaller than the paper size, the display screen is set to a value equal to or slightly larger than the size of the document section. When the display screen size is larger than the paper size, as shown in FIG. 4, the position of the document section is vertically aligned, and the arithmetic processing is performed so that the paper position moves right and left.

Next, the flow of the above processing will be described with reference to the flowchart of FIG. When document creation is started, it is first checked whether a binding margin is set (step S
1) If it is set, it is determined whether or not the left and right values are different (step S2). If the left and right values are different, the size of the document portion is calculated by subtracting the margin and the binding margin from the paper size at the time of printing (step S
6) The location of the center of the document portion is calculated (step S4), and the center of the document portion is set so as to be aligned with the center of the display screen (step S5).

Further, it is checked whether or not the size of the display screen is different from the paper size at the time of printing (step S3). If the size is different, calculation and setting are performed so that the center of the document portion is aligned with the center of the display screen as described above. I do. At this time, when the display screen size is smaller than the paper size, the display screen is set to a value equal to or slightly larger than the size of the document section, and when the display screen size is larger than the paper size, the display section of the document section is set as shown in FIG. The positions are vertically aligned, and arithmetic processing is performed so that the position of the sheet moves left and right.

The document created in this way is input to the output device 6, where it is printed on paper and discharged. The processing of this flowchart is performed by the central processing unit 2.

[0023]

As described above, according to the present invention,
When creating a document, when using a double-page spread document with different margins on the left and right side by side in a line vertically, and scrolling, the document part being created can be scrolled straight without swinging left and right. Since the left and right positions of the printing paper are moved, it is easy to use.

Further, by setting the display screen size to be the same as that of the document display unit or to make the display screen size slightly larger than the document display unit size, when the paper size is larger than the display screen size, the left and right binding margins are set. Since no part is displayed, unnecessary parts are not displayed even when the display screen is scrolled, so that it is easier to use.
