DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

Example 1. FIG. 1 is a system configuration diagram adopting the large-volume character display system according to the present invention. In FIG. 1, a CRT 2 as a character display unit capable of displaying an arbitrary character size, and a character size determination unit as a character size determination unit for calculating the character size to be displayed based on the number of lines or columns of a document displayed on the CRT 2. And a character arrangement control unit 6 as a character arrangement control unit for controlling the arrangement of characters to be displayed, and a keyboard as an input unit having keys for making various settings, scrolling the display screen, and moving the cursor. 8 and. Note that this system is realized by a general computer equipped with software for creating, editing, and displaying documents, and the character size determination unit 4 and the character arrangement control unit 6 are executed by the CPU and the CPU, and will be described later. It is realized by an application that performs processing.

FIG. 2 shows the data image of document 1 and document 1.
It is the figure which showed the example of a screen at the time of displaying on CRT2.
In this embodiment, the display screen is an edit work area 12 for editing characters and an unedited work area 14a, 1 which is not used.
4b and manage. The editing work area 12 in FIG. 2 is formed by three lines in the center of the screen. Cursor 16
Represents the editing position, but in the present embodiment, it can be moved only within the range of the editing work area 12. Conversely, the movable range of the cursor 16 becomes the editing work area 12.
Further, in FIG. 2, the width 18 of the screen that can be displayed and the character string length 2 are shown.
0 is shown.

A characteristic of this embodiment is that a CRT is used.
2 is to calculate the character size of each line based on the number of lines to be displayed in 2, and to display each character on the CRT 2 with the calculated character size. In the present embodiment, as in the screen example shown in FIG. 2, the editing work area 12 is displayed in a character size that is normally used and is easy to edit, and the unediting work areas 14a, 14
In b, a character size smaller than the editable character size displayed in the editing work area 12 is displayed. Further, the characters displayed in the unedited work areas 14a and 14b can be calculated, and the characters are displayed smaller as the distance from the edit work area 12 increases. By displaying the character size in multiple stages in this way, it is possible to display the character to be edited in a character size that is easy to see and edit, and to increase the amount of character data to be displayed by reducing the character that is not the object of editing. You can Therefore, the entire document can be displayed on one screen.

FIG. 3 is a flow chart showing the processing for determining the character size to be displayed in this embodiment. The method for determining the character size and the operation of this system will be described below.

First, when the number of lines Xn included in the document 1 is designated by the user (step 11), the central line N = Xn / 2 of the document 1 is rounded off from the number of lines (step 12). If the number of lines in document 1 is Xn = 51, the central line N of document 1 is 51/2 = 25. Next, the editable range M designated by the user is acquired (step 13).
This range M is an editable range and corresponds to the number of lines assigned to the editing work area 12 in this embodiment. In the screen example shown in FIG. 2, M = 3. Further, since the editing work area 12 in the present embodiment is fixed to the center of the screen, it is possible to form a well-balanced screen layout by setting the range M to an odd number.

Next, from the first line of the document 1 to the Xn = 51th line, each line is CRT-processed by sequentially performing the processing described below.
Allocate to screen 2. First, the display position of the first line of the document 1 on the screen is specified. Since the present embodiment is characterized in that the entire one page of the document is displayed on one screen, the first line of the document 1 should be always displayed when the initial screen of the document 1 is displayed. Therefore, the first line, which is the first line of the document 1, is located on the first line of the screen regardless of the size of the characters. Further, strictly speaking, the center line N of the document 1 is shifted by one line depending on the value of the number of lines Xn, but it is assigned to the center on the screen when the initial screen is displayed. Therefore, in the initial screen display, the center line N of the document 1 and the center line on the screen are the same.

Here, the row X to be assigned to the screen is 1 in this case.
After comparing the second line with the center line N to obtain the degree | X−N | of moving back and forth from the center line of the screen (step 16), | X
-N | and half of the range M of the editing work area 12 (M / 2)
And the number obtained by rounding down the remainder number (hereinafter simply referred to as "M / 2") is compared (step 17). By comparing, it is checked whether the allocation target row X is within the range M. That is, |
When X−N | is equal to or smaller than M / 2, the allocation target row X
Can be determined to be a line displayed in the editing work area 12. In this case, each character of the allocation target line X is displayed with the size S (step 18). Size S
Is the size set by the user when it is determined to be easy to read and edit. On the other hand, when | X−N | = 24> 1 and | X−N | becomes larger than M / 2, as in the case of X = 1 just described, the reduction ratio α (0 <α The character size αS is calculated by multiplying <1] (step 19). The calculation method of the reduction rate α will be described later. The above process is repeated until all lines, that is, the 51st line (step 2).
0). As a result, each line of the document 1 has the edit work area 12
Alternatively, the characters assigned to the unedited work areas 14a and 14b and displayed in the edit work area 12 have the size S, and the characters displayed in the unedited work areas 14a and 14b have the size αS.
Will be displayed respectively.

By the way, the present embodiment is characterized in that the character size displayed in the unedited work areas 14a and 14b is smaller than the character size displayed in the edit work area 12 as described above. Work area 1
Another feature is that the character size is gradually reduced as the distance from 2. Hereinafter, setting of the number of steps and the reduction rate α for stepwise reduction will be described.

Consider, for example, a case where the reduction ratio α is changed in 7 steps on one screen, that is, every 3 steps in each of the unedited work areas 14a and 14b, and displayed (vertical length of one screen) = M. × S + 2 × (α ₁ M ₁ S + α ₂ M ₂ S +
α ₁ , α ₂ , and α ₃ satisfying α ₃ M ₃ S) are the reduction ratios at each stage. M ₁ , M ₂ and M ₃ are the number of rows in each stage. In the case of the document of Xn = 51 described above, M =
3, M ₁ = 4, M ₂ = 10, M ₃ = 10, α ₁ = 0.
5, α ₂ = 0.3, α ₃ = 0.1 can be displayed. The character size determination unit 4 determines the reduction ratios α ₁ , α ₂ , α _{3 and the} number of lines M ₁ , M at each stage that satisfy the above formula.
₂ and M ₃ are calculated. The combination of calculated values may be stored in the table in advance, may be calculated using a certain rule, or may be set by the user. In addition, the number of stages is set to each unedited work area 14a,
It is also possible to increase the maximum size until all the lines included in 14b have different character sizes.

When it is desired to correct characters other than those displayed in the editing work area 12 after the initial screen is displayed, the keyboard 8
Is operated to move the cursor 16 in the vertical direction. In this embodiment, the cursor 16 can be moved only in the editing work area 12. When the cursor 16 reaches the upper and lower ends and is further moved, the editing work area 12 is fixed at the center of the screen, and therefore the entire document displayed on the screen moves in the vertical direction. With the movement of the document 1, the flow shown in FIG. 3 is executed, and the character size of each line is recalculated. Therefore, when the characters in the unedited work areas 14a and 14b are scrolled and enter the edit work area 12, the characters are displayed in the character size S. You can modify it. Further, since the editing work area 12 is fixed at the center of the screen, both the context of the document 1 can be grasped.

In the present embodiment, as shown in FIG. 2, the characters in each line are displayed by the character arrangement control unit 6 at the center of the line, specifically ((horizontal width of displayable screen 18−character string length 20. ) / 2) is so-called centered and displayed based on the position calculated in (2).

As described above, according to the present embodiment, by displaying the characters other than the editing target small, more characters can be displayed on one screen while keeping the size of the editing target character easy to read and edit. The character data of can be displayed. Further, the editing work area 12 is fixed to the center, and the display characters are displayed stepwise as the distance from the editing work area 12 increases.

Since the character size displayed in the editing work area 12 can be freely set, each user can perform the editing work with a character size suitable for himself / herself.

Although only the characters displayed on the CRT 2 are shown in FIG. 2, the range of the editing work area 12, the unediting work areas 14a and 14b, and the difference in the setting mode from each of the following embodiments will be described. Displaying an indicator indicating is just a design matter.

Further, although the keyboard 8 is used as the input means in this embodiment, a mouse may be used.

Example 2. In the first embodiment, the characters in each line are centered and displayed with the center of the line as the reference, but in the present embodiment, the characters are displayed by aligning them to the left with the left end of the line as shown in FIG. It is characterized by In this way, by displaying the text at the left end, it is easy to read without any delay. Also, the status of columns can be grasped. The calculation method of the character size in each line and other effects are the same as those in the first embodiment, and thus the description thereof is omitted.

Example 3. The characters on each line are
In the embodiment, the centering display is performed based on the center of the line, and in the second embodiment, the characters are displayed at the left end, but in the present embodiment, the characters are equally spaced in each line as shown in FIG. It is characterized by being placed and displayed in. As shown in FIG. 5, the character spacing in each line is
It can be calculated by the character string length 22 / (the number of characters in each line-1), and each character is displayed at the character interval calculated from the character display start position in each line. By displaying like this,
The layout of the document 1 can be easily understood because the positional relationship with the characters existing above and below in the document 1 included in another line of the reduced characters is maintained. Since the calculation method and effect of the character size in each line are the same as those in the first embodiment, the description will be omitted.

Example 4. In each of the above-described embodiments, the reduction ratio in each of the unedited work areas 14a and 14b is obtained stepwise and the characters are displayed. In the present embodiment, by making the reduction ratio uniform, as shown in FIG.
The character sizes displayed in a and 14b are all the same. That is, the character size has two levels: the edit work area 12 and the unedited work areas 14a and 14b. As described above, by uniformly reducing the reduction rates in the unedited work areas 14a and 14b, the reduction rate can be calculated very easily. That is, it is possible to easily calculate the size of the unedited work areas 14a and 14b and the number of lines displayed in the unedited work areas 14a and 14b.

Further, in the case of handling a predetermined document style, it is possible to previously set the reduction rate as a constant, and if it is set as a constant, the calculation of the character size becomes unnecessary and the fonts used are reduced. This makes it possible to display a large amount of character data at high speed.

Example 5. In each of the above embodiments, when the editing work area 12 is fixed to the center of the screen and the cursor 16 is moved further after reaching the upper and lower ends of the editing work area 12,
The entire document displayed on the screen, that is, the screen was scrolling. The present embodiment is characterized in that when the cursor 16 is further moved, the editing work area 12 moves within the screen according to the movement of the cursor 16. FIG. 7 is a diagram showing a case where the editing work area 12 is located below the center of the screen in this embodiment. As compared with the case where the editing work area 12 is fixed to the center of the screen, the characters displayed from the center of the screen to the upper part are displayed smaller.

As described above, by setting the edit work area 12 to be movable, the document 1 to be displayed can be fixed and edited in page units. Needless to say, the line to be edited is displayed in a character size that is easy to edit because it is included in the editing work area 12. Also,
The user can edit the document 1 at any position without fixing it on a page-by-page basis.

Example 6. In each of the above embodiments, the case of reducing the size in the row direction, that is, the vertical direction has been described, but in the present embodiment, the feature is that the size is reduced in the column direction, that is, the horizontal direction. That is, FIG. 8 is a diagram showing an example of a screen in this embodiment. It is possible to display and edit the entire horizontally long document such as the document 11 having a large number of characters included in one line on one screen. In this case, as shown in FIG. 8, the edit work area 112 in the column direction and the unedited work areas 114a and 114b are provided on both sides of the edit work area 112. The font size becomes smaller.

The editing work area 112 in this embodiment is
Similar to the fifth embodiment, the editing work area 112 moves within the screen according to the movement of the cursor 16, and the display screen does not scroll. Therefore, the operation is effective when the horizontally long document 11 is edited.
