Abstract

PURPOSE:To attain document edition without changing the layout of the whole document at the time of changing paper size in a format. CONSTITUTION:A value obtained by adding character size 31 to a character interval 32 is multiplied by the number of columns 33 to find out the number of horizontal printing dots. Printing width 34 is calculated based upon the number of horizontal printing dots and the resolution of a printer. Since paper width 38 is a value determined by each paper size, a left margine 51 and printing width 52 are determined from the paper width of pawer with different paper size based upon the rate of the left margine 40 corresponding to the paper width 38 to the calculated printing width 34. Then the printing width 52 is converted into the number of dots and the converted value is divided by the number of columns 33 to find out the number of dots 55 per digit. Character size 56 and a character interval 57 are determined from the rate of the character size 31 to the character interval 32 and the number of dots 55. A line interval 59 is determined by subtracting the character size 56 from the number of dots 58 per line which is found out similarly to said method. When the line interval 59 is a negative value, the interval 57 is rearranged by reducing the size 56 to determine the interval 59.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus having a function of changing document format information.

[0002]

2. Description of the Related Art Conventionally, when proofreading a document input by a document editing apparatus, if the paper size of the set format information is changed, the size of the basic character (double-byte character) does not change, The number of digits that the user can enter, the number of lines, the character spacing,
It was necessary to set the line spacing again and adjust it to suit the paper size.

[0003]

In the case of this conventional device,
When changing to a paper size smaller than the paper size at the time of inputting characters, the maximum number of digits that can be input is less than the maximum number of digits that can be input for the previous paper size, and the character data for one line becomes two lines. This causes a problem that the layout of the entire document is changed. Therefore, it takes time and effort for the user to reset the layout, and the efficiency of document proofreading decreases.

The present invention solves the above problem, and an object of the present invention is to provide a document editing apparatus capable of editing in the same state as the layout of a document before change by changing the size of characters.

[0005]

In order to solve the above-mentioned problems, the document editing apparatus of the present invention, when the created document is set to a different paper size and the format is changed, the paper size and the size of the print range are set. The appropriate margin, character spacing, line spacing, and character size are automatically calculated from the ratio.

[0006]

According to the present invention, since the character size is changed according to the paper by the above means, the whole document can be easily enlarged or reduced, and the entire document can be edited without changing the layout.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a document editing apparatus according to an embodiment of the present invention. In FIG. 1, this device has a central processing unit (hereinafter referred to as CPU) 1 as a core, and has a keyboard 2 for inputting characters, a storage device 3 for holding the input characters as a document, and a memory. It comprises a display device 4 for displaying a document and a printer device 5 for printing a stored document.

The format information necessary for creating a document is stored in the storage device 3, and when the operator hits the keyboard 2, the character code is stored in the storage device 3. The format information relating to the document creation is as shown in FIG.

In FIG. 2, the format information includes a paper size 11 representing the size of the paper, a paper orientation 12 representing the orientation of the paper to be printed, and a print orientation 1 for printing characters vertically or horizontally.
3, upper margin 14 indicating the upper margin toward the paper, left margin 15 indicating the left margin, character size 20 indicating the basic size of characters to be printed, 1 number of lines per page 18, number of columns per line 19,
It is composed of a character space 16 that represents the space between characters in the digit direction and a line space 17 that represents the space between characters in the line direction.

As for the format setting method, the operator presses a specific key on the keyboard 2 so that the CP
U1 reads each value of the format information from the storage device 3,
It is displayed on the display device 4 as a format parameter.
FIG. 3 shows an example of the display. When a new document is created, the standard values of all parameters are initially set and stored in the storage device 3 in advance. Regarding the layout change 21 in FIG. 2, "Yes" (1 as a value) is used when formatting is performed without changing the conventional basic character size, and the character size is changed without changing the document layout as in the present embodiment. When changing automatically, “No” (value 0) is stored in the storage device 3. The state is displayed at the bottom of the screen in FIG.

When the operator sets the layout change to "no", the format information that can be set by the operator is limited to the paper size and the printing direction, and other parameters cannot be set. When the operator changes the paper size, CPU1
Automatically determines the upper margin, the left margin, the character spacing, the line spacing, and the character size, and displays each value on the display device 4. FIG. 4 shows the screen display contents when the paper size is changed to B5 by taking the paper size A4 of FIG. 3 as an example. When the operator determines the paper size, the keyboard 2
Hit a specific key of. The changed parameters are stored in the format information 11 to 20 of the storage device 3.

Next, the top margin, left margin, character spacing, line spacing,
The method of determining the character size will be described. FIG. 5 is a diagram showing the content of each format information for a sheet and the content of each format information when the sheet size is changed.

First, the number of print dots in the horizontal direction is obtained by multiplying the sum of the character size 31 and the character spacing 32 by the number of digits 33. Based on that value and the resolution of the printer device 5, the print width 34
Calculate (unit is millimeter). Similarly, the print length 35 is calculated from the character size 31, line spacing 36, and line number 37.

Since the paper width 38 and the paper length 39 are numerical values determined by each paper size, the left margin 40 with respect to the paper width 38
From the ratio of the calculated print width 34 and the paper width of different paper size, the left margin 51 of different paper size, the print width
52 is determined. Similarly, the upper margin 53 and the print length 54 are determined from the upper margin 41, the print length 35, and the paper length 39 of the original paper size.

Next, the print width 52 is converted into the number of dots and divided by the original number of digits 33 to obtain the number of dots 55 per digit. The character size 56 and the character interval 57 are determined from the ratio of the original character size 31 and the character interval 32 and the number of dots 55. Similarly, the print length 54 is converted to the number of dots and divided by the original number of lines 37 to obtain the number of dots 58 per line, and the character size 56 is subtracted to determine the line interval 59. To be done. When the line interval 59 has a negative value, the character size 57 is readjusted by reducing the character size 56, and the line interval 59 is determined.

[0016]

As described above, according to the present invention, even if the format is changed to a different paper size, the upper margin, the left margin, the character spacing, the line spacing, and the character size suitable for the paper are automatically determined. Therefore, the operator can proofread the document without being aware of the layout of the document, and the efficiency of document creation is significantly improved. In addition, the document can be easily enlarged or reduced.
