Abstract

PURPOSE:To obtain the documents displayed on a display device in the form of the printed result by using a display device which displays the noticed lines with spaces set based on the maximum vertical width detected by a detector. CONSTITUTION:A keyboard 7 produces the height Cn set against the reference character height. Then a CPU 1 detects the maximum height Cm of the characters of a line used for evolution. The comparison is carried out between both heights Cm and Cn. In the case Cn<=Cm, that is, when it is decided that the height of a character pattern does not exceed the maximum height of the noticed lines, a produced character pattern is evolved in the line pitch set before evolution. While a new line pitch is calculated for execution of the pattern evolution in the case of Cn>Cm. The difference DELTAl of the Cn is calculated to the reference character height and a new line pitch L is obtained by adding the difference DELTAl to a reference line pitch. Then the character patterns in the noticed lines including a character pattern produced based on the pitch L are evolved to a VRAM 3 and displayed on a CRT 4 in the form of the printed result.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document processing device, which creates a document by developing characters and symbols of different sizes on a display screen capable of displaying multiple lines. It is.

[Prior Art] Document processing devices in recent years are not only used for simply creating business documents, but also have richer editing contents and functions.

For example, regarding character types, it is now possible to edit not only full-width characters, but also half-width, double-width, double-height, and even double-width vertical and horizontal characters while displaying them on the display screen.

Normally, documents are created using full-width characters, but when trying to input subsequent character strings in double-height, for example, in most cases, the process was done by pressing a key to set the double-height.

Note that returning to the original state was achieved by pressing the full-width key.

[Problems to be Solved by the Invention] By the way, on the document creation screen, the positions where characters can be developed are fixed in advance.

FIG. 6 is a diagram showing a general state during document creation. In addition, 60 in the figure is the display screen, 61 is the cursor, and 62 is the cursor.
is a character expandable frame (doesn't have to be displayed or not)
It is.

Now, going back to the basics of the explanation, under these circumstances, for example, if you set double-width and enter a character on the keyboard, that character will straddle the frame where the cursor 61 is located and the frame to the right of it. Characters with double width will be displayed. In other words, the input characters followed this character expandable frame.

However, if an attempt is made to input, for example, a double-height character at the position of the cursor 61, a problem arises in that the character "ra" above the cursor is erased by the input character. Furthermore, even if there is no character on the line before the cursor position, when a double-height character is input, there is virtually no gap between the line where the cursor is located and the line before it. That is, (although it is not clear on the display screen), the line "From now on..." and the line "In the afternoon..." in the figure are printed in contact with each other. This is because if these lines are not printed in contact with each other, double-height characters will be printed vertically separated.

Therefore, when attempting to input double-height characters under the situation shown in the figure, it is necessary to insert lines between these lines, but this is an extremely troublesome operation for the operator. Furthermore, even if you enter double-height characters after inserting a line, for example, if you insert a character string in a line with "From here...", the string that goes beyond the end of the line will be placed above the double-height character. The problem is that the above-mentioned problem still occurs if the line is expanded to a line that is

The present invention has been made in view of the prior art, and solves these problems and allows
The present invention aims to provide a document processing device that can set and edit desired characters.

[Means for solving the problem] In order to solve this problem, the present invention has the following configuration.

In other words, in a document processing device that creates a document by developing characters and symbols of different sizes on a display screen that can display multiple lines,
The present invention includes a detecting means for detecting the maximum vertical width of a group of characters and symbols constituting the line of interest, and a display means for displaying the line of interest with line spacing based on the maximum vertical width detected by the detecting means.

[Operation] In the configuration of the present invention, the display means displays the line of interest with line spacing based on the maximum vertical width of the character symbol group of the line of interest detected by the detection means.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Description of the schematic structure of the document processing apparatus (FIG. 1)> FIG. 1 shows a schematic structure of the document processing apparatus in the embodiment.

In the figure, reference numeral 1 denotes a CPU that controls the entire device, and operates according to a program stored in a program area 2a in a memory 2.

Note that the program area 2a stores programs related to the flowcharts of FIGS. 2 and 5. Also,
The document information being edited is developed in the document area 2b in the memory 2. 3 is a VRAM, and the image data developed here is displayed on a CRT 4, which is one of the display devices. Reference numeral 5 denotes a character pattern generator capable of generating multiple types of character patterns.
The character pattern corresponding to the character code in b is stored in VRAM3.
Used when expanding to . The character types generated by this character pattern generator 5 include not only full-width and double-width characters, but also
Generate characters that are 1.5 times larger than full-width characters (this can be achieved if the character pattern is stored in advance). 6 is CRT
4 is a transparent pressure-sensitive touch panel located in front of the display screen, and information on the position touched by the operator's finger is displayed on C.
It is taken into PU1. F is a keyboard for inputting various information, and 8 is an external storage unit (for example, a magnetic disk device) capable of storing a plurality of document information. Further, 9 is a printing section.

Description of Document Editing Process (FIGS. 2(a) and (b))> First, an overview of the processing of the document processing apparatus in the embodiment will be described. In addition, input of various information in the embodiment is performed using the keyboard 7.
In addition, selection is made by specifying with a finger or the like a surface on the touch panel 6 that corresponds to various icons displayed on the display screen of the CRT 4. In addition, the following explanation “...
・"Button" is an icon corresponding to various processes displayed on the display screen, and the touch panel 6 corresponding to that button
The action of touching the position of is simply called "touching."

Now, when the power is turned on and a menu related to document creation is selected, an area is secured on the display screen of the CRT 4 in step S1 where a multi-line document related to document creation can be displayed. A group of buttons will be displayed.

Now, in step S2, it is determined whether or not the editing end button has been touched. When this determination is "YESoo", the editing process is ended and the process returns to the process before entering this series of flowcharts.

If it is determined in step S3 that there is a character input from the keyboard 7, the process proceeds to step S4, and a process of incorporating the kana-containing sentence converted into kana-kanji into the editing screen is executed.

At this point, the character pattern is developed in the VRAM 3 with the character size set in step S6, which will be described later.
The details will be described later.

Further, if it is detected in step S5 that the operator has touched the character type setting button, the process advances to step S6.
Processing is executed to set the display mode of the editing screen (number of line digits, etc.), whether it is Japanese or English, character size, etc.

If it is determined in step S7 that the character type change button has been touched, the process moves to step S8, where the character type is set, a range in the document that is already displayed is specified, and a character string within the specified range is set. Process to change to the specified character type.

Further, if a touch on the edit button is detected in step S9, the process moves to step SIO, and a desired editing action such as left alignment, right alignment, or centering of the character string is selected and executed.

Furthermore, if it is determined that the read/save button has been touched in step S11, the user selects whether to save the document being edited or read a new document in step S12.
Perform processing based on each selection.

If it is detected in step S13 that the front/picture button has been touched, the process moves to step S14 to specify which one to select, read out each subroutine depending on the selection, and display it on the editing screen. Create a table or picture interactively.

Furthermore, when the format/print button is touched in step S15, the process moves to step S16, where the format is changed and the layout is displayed based on the changed format, and printing is executed if necessary.

In this manner, various processes are sequentially executed based on information from the keyboard 7 or touch panel 6.

Explanation of manual processing related to character type change (Figures 3 to 5)> The screen during document creation in the example (30 in the figure) is
Shown in Figure (a).

In addition, in the embodiment, a state in which normal characters (for example, double-byte characters are initially set) are manually written is shown. Further, 31 in the figure is a cursor.

Now, in this state, we now set larger characters in the vertical direction (in this case, 1.5 times larger in the vertical direction) (step S6 described above).
), and after inputting "general meeting", double-byte characters are set again and "ni" is inputted, as shown in FIG. 3(b).

The point to note here is that the line spacing between "From now on..." and "In the afternoon" in Figure 3(a) is different from that in Figure 3(b).This line spacing This change occurs when the character pattern group "general meeting" is generated from the character pattern generator 5 and expanded to the VRAM 3. In the embodiment, the height of the generated character pattern group is
Displays the entire line only if it is higher than the maximum height of the entire character pattern in the line of interest before expansion (VRAM3)
It is made to redeploy (or move in parallel) downward by a predetermined amount.

It is necessary to calculate the amount of change between lines, but in the example, the difference between the maximum height in one line including the generated character pattern and the height of the basic character pattern is added to the standard line pitch. did.

That is, in FIG. 4, the new row pitch L is calculated using the following formula.

L = basic line pitch jLo + size increase △1 Also, actually, instead of detecting the size of the character pattern in VRAMB, it detects the inside of the document area 2b where the character code corresponding to the display screen is stored. Achieve this by researching. This is because in the document area 2a, not only each character code but also the character type code associated with that character code are arranged, and by identifying the character type, you can see what size or type it is on the display screen. This is because it can be determined whether the characters are displayed.

The contents of step S4 in FIG. 2 based on the principle explained above will be explained with reference to the flowchart shown in FIG.

First, in step S51, a character pattern (in the case of kana-kanji conversion, a kanji pattern) based on data input from the keyboard 7 is generated at a set size (height Cn). Next, in step S52, the maximum height Cm of characters in the line to be expanded is detected, and in step S53, these Cn
, Cm are compared and judged.

If this judgment is "Cn50m", that is, if it is judged that the height of the generated character pattern does not exceed the maximum height in the line of interest, the process proceeds to step S54, and the character pattern is generated at the line pitch before expansion. Expand the character pattern.

On the other hand, if it is determined in step S53 that Cn>Cm'', the generated character pattern cannot be loaded into the VRAM 3 as it is, so a new line pitch is calculated in steps 355 and subsequent steps, and the pattern redeployment process is executed.

First, in step S55, the difference Δ°C between Cn and the reference character height is calculated. In the next step S56, the difference Δ° C. is added to the reference row pitch and the result is updated as the new row pitch L. Then, in step S57, character patterns in the line of interest including the generated character pattern are developed in the VRAM 3 according to the calculated line pitch L.

In the process described above, when developing a generated character pattern, it is determined whether or not the line pitch needs to be changed depending on the character pattern, but the present invention is not limited to this. For example, every time a character pattern is generated, the difference between the reference character height and the maximum height in the line of interest containing that character pattern is calculated, the line pitch is updated unconditionally according to that difference, and the entire line is redeployed. It's okay.

As explained above, according to this embodiment, the line pitch is changed based on the size of the characters, so even if double-height characters are manually displayed, the line spacing can be adjusted automatically. Become. Therefore, it is possible to view the document displayed on the display device as a printed result.

In addition, when you enter a double-width character, for example, the characters above it will no longer be erased, and the space between two lines where that character (double-width character) is located will be touched when actually printed. There is no need to judge whether or not the image will be printed.

According to the embodiment described above, for example, the line spacing of a document created using only full-width characters and the line spacing of a document created using characters of different heights appear to be visually constant.

Further, in the embodiment, the case where an input character pattern is expanded has been described, but originally, the AW collection processing of a document processing device includes functions such as insertion, deletion, and furthermore, transfer. It goes without saying that the processing contents of the embodiments are also executed in these processes.

For example, in the case of deletion, if the maximum height of the character pattern in that line becomes lower as a result of the deletion, then the line pitch may be changed to smaller for display.

[Effects of the Invention] As explained above, according to the present invention, as a result of the editing process,
By displaying a document while changing the line pitch according to the character type in the line of interest, it becomes possible to view the document displayed on the display device as a printed result.
