Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a document processing device such as a word processor and a personal computer, inputs an input character to a text cursor position, and
The present invention relates to a character string processing method for updating a cursor position in an input direction such as horizontal writing / vertical writing which is formatted in advance.

[0002]

2. Description of the Related Art Conventionally, in a document processing apparatus, a cursor on a text screen is normally moved from right to left in the case of horizontal writing and upward in the case of vertical writing according to a setting format every time a character is input. It moves from the bottom to the bottom, but it may move from the bottom to the top or the left to the right at the time of a line break or backspace between them. By the way, in order to create a unique and effective guide, etc., it is sometimes desirable to put a vertical document in a horizontal document and emphasize a part of it.In such a case, operate the cursor key. And then move the cursor vertically, or temporarily change the formatting to vertical writing.

[0003]

However, in the method of operating the cursor key and inputting a vertically written character string without changing the horizontal writing format, the cursor moves one character to the right every time one character is input. Therefore, it is necessary to repeatedly perform the troublesome operation of operating the left cursor key to return the cursor and then operating the down cursor key to move in the vertical direction many times. Also, insert characters /
When the deletion is performed, the character arrangement state of the entire document may be destroyed, and even the horizontally written document may be affected, and it is extremely difficult to partially edit only the vertically written document. On the other hand, in the method of temporarily changing the setting format to vertical writing, it is necessary to perform the troublesome operation of switching from the text screen to the formatting screen and then from the formatting screen to the text screen many times. Each time a document was input, the troublesome operation of having to specify the document range was required. This has a similar problem even when a horizontal writing document is inserted in a part of the vertical writing document. An object of the present invention is to temporarily input a vertical writing document in a horizontal writing document or a horizontal writing document in a vertical writing document without temporarily changing the setting format. It is to be able to change the character string input direction to any direction. Further, an object of the present invention is, for example, when a vertically written document is mixed in a horizontally written document or when a horizontally written document is mixed in a vertically written document, without changing the setting format,
This is to allow the character string editing direction to be temporarily changed to an arbitrary direction.

[0004]

Means for Solving the Problem and Its Action The means and action of the first invention are as follows. In a document processing apparatus for inputting an input character to a text cursor position and updating the cursor position to a pre-formatted character string input direction, at least a first character string input direction and a second character string input direction are provided. Of the two, if the first character string input direction is pre-formatted, it is determined whether or not the second character string input direction is switched while retaining the formatting contents. When a character is input while switching to the input direction, the input character is input to the text cursor position, and the cursor position is updated to the second character string input direction. When the first character string input direction is switched to the second character string input direction, whether or not there is a character string that has already been input from the current cursor position in the first character string input direction. Alternatively, when it is determined that the character string exists, a space may be inserted between the current text cursor position and the character string. Further, the first character string input direction and the second character string input direction may be arbitrarily switched and designated by operating a predetermined key. Therefore, for example, when partially inputting a vertical writing document in a horizontal writing document or when partially inputting a horizontal writing document in a vertical writing document, temporarily input the character string without changing the setting format. The direction can be changed to any direction. The means of the second invention and its operation are as follows. In a document processing device that performs editing processing in accordance with a character string input direction that has been preformatted when document editing is instructed, at least a first character string input direction, a second character
If the first character string input direction of the character string input directions of is formatted in advance, it is determined whether or not the second character string input direction is switched while keeping the format setting content, When the document editing is instructed while switching to the second character string input direction, the editing process is performed on the character string existing in the second character string input direction. The means of the third invention and its operation are as follows. In a document processing device that performs editing processing in accordance with a character string input direction that is preformatted when a document edit is instructed, at least the first character string input direction and the second character string input direction When the character string input direction of 1 is pre-formatted, it is determined whether or not the character string input direction is switched to the second character string input direction while keeping the format setting content, and switched to the second character string input direction. While the text is being edited, the identification information indicating the input direction is added to the characters that have been input, and when the document is edited, the editing process is performed according to the second character string input direction with respect to the character string to which the identification information is added. To do. Therefore, for example, when a vertical writing document is mixed in a horizontal writing document or when a horizontal writing document is mixed in a vertical writing document, the character string editing direction is temporarily changed to an arbitrary direction without changing the setting format. Can be changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing a document processing device such as a word processor. The control unit 1 is a block diagram showing an outline of the overall configuration of the document processing apparatus. Control unit 1 is R
A central processing unit that controls the overall operation of this document processing apparatus according to various programs stored in the OM2, etc. When a character code is input from the key input unit 3, this character code is converted into display data. In addition to displaying and outputting on the text screen of the display unit 4, the character code is stored in the input buffer 5-1 in the RAM 5. in this case,
The control unit 1 causes the input character to be displayed and output at the text cursor position indicated by the cursor pointer 6, and the value of the cursor pointer 6 according to the character string input direction (vertical writing / horizontal writing) preset in the format memory 7. Is updated by one character. Such an operation is executed every time one character is input from the key input unit 3, and when a confirmation operation is performed thereafter, the kana-character string in the input buffer 5-1 is subjected to kana-kanji conversion or non-conversion processing, and the RAM 5 Document memory 5-
2 is stored.

As shown in FIG. 2, the format memory 7 stores the line pitch, digit pitch, character size, etc., as well as horizontal / vertical writing format information. When changing the preset default format. When the change is instructed from the key input section 3, the control section 1 rewrites the contents of the format memory 7 according to the instruction. Here, on the key input unit 3, there is provided an input direction temporary switching key K for temporarily switching the input direction of a character string from a horizontal writing document to a vertical writing document without changing the setting contents of the format memory 7. When the input direction temporary switching key K is operated, the control unit 1 temporarily switches the character string input direction. For example, when horizontal writing is set in the format memory 7, the control unit 1 interchanges the row pitch and the digit pitch when reading the line pitch and the digit pitch from the format memory 7. That is, the row pitch during horizontal writing is read as the digit pitch during vertical writing, and the digit pitch during horizontal writing is read as the row pitch during vertical writing. The same applies when the vertical writing is set in the format memory 7, and when the input direction temporary switching key K is operated, the line pitch and the digit pitch are changed without changing the setting contents of the format memory 7. Read each other.

FIG. 3 conceptually shows the contents of the document memory 5-2. When horizontal writing is set in the format memory 7, the input direction temporary switching key K is operated to temporarily input a character string. The data structure when the direction is switched to vertical writing is shown as an example. That is, when a vertically written document is partially inserted in a horizontally written document, an identification code indicating vertical writing is added to each character of the vertically written character code. In this case, at least one character space code is forcibly inserted between the vertically written character code and the horizontally written character code. The memory width for one line is obtained from the number of digits of format information. When an editing instruction is given to the document data in the document memory 5-2, the control unit 1
Edits the document data in the document memory 5-2 according to the editing contents (character insertion, deletion, copying, moving, etc.), and at that time, edit processing is performed for each of the horizontal writing document and the vertical writing document.

The operation of this embodiment will be described below with reference to the flow charts shown in FIGS. 4 to 6 are flowcharts exemplifying operations when a vertical writing document is partially input in a horizontal writing document or when a document in which a vertical writing document is partially mixed in a horizontal writing document is edited. is there. Further, FIG. 7 shows an example of a text screen. FIG. 7A shows a cursor movement direction and a document example when horizontal writing is set in the format memory 7, and FIG. 7B shows an input direction. The cursor movement direction and the document example when the character string input direction in which the temporary switching key K is operated are switched to the vertical writing mode are shown.

First, the operation of inputting a document will be described. When a key input is made in the key input waiting state (step A1), it is checked whether or not the input direction temporary changeover key K has been operated (step A2). If it is assumed that a character input has been made, the process proceeds to step A6. , Vertical cursor flag is O
Check if it is N. Here, the vertical cursor flag is OF when the horizontal writing is designated at the time of formatting.
If F or vertical writing is designated, it is turned on. Since the horizontal writing is currently set in the format memory 7,
The process proceeds to step A12, where the input character is input buffer 5-1.
Is temporarily stored, and the input character is displayed and output at the text cursor position indicated by the cursor pointer 6. Then, if the current cursor position is not the end of the line for horizontal writing (step A13), the control unit 1 moves the cursor horizontally (to the right) by one character based on the setting format (step A14). On the other hand, if the horizontal line end is detected in step A13, the process advances to step A17 to move the cursor to the horizontal character start position of the next lower line. Such an operation is executed for each character input. If no conversion / kana-kanji conversion is instructed for the input kana character string, the process proceeds to step A18, where kana-kanji conversion or non-conversion processing is performed. Then, an attribute code or the like is added to each character code forming the fixed character string and stored in the document memory 5-2 (step A19). The vertical cursor flag is referred to, and if it is turned on, an identification code indicating vertical writing is added to each character (step A2).
0), the step A20 is skipped because it is at the time of creating a horizontally written document in which the vertical cursor flag is OFF. In this way, it is assumed that the horizontal writing document as shown in FIG.

Now, in the example of the document shown in FIG. 7A, there is a vertically long margin portion on the left side thereof, and a vertically written title name is inserted in this portion. In this case, since horizontal writing is set in the format memory 7, when inputting a vertically written document without changing the setting contents, the input direction temporary switching key K is operated. Then, it is detected in step A2 and the process proceeds to step A3.
If the vertical cursor flag is ON, it will be set to OFF and OF
If it is F, it is set to ON. Next, the format information according to this flag state is fetched from the format memory 7 (step A4). The vertical cursor flag is now ON from OFF
Since it is switched to, the row and column information (row pitch, digit pitch, number of rows, number of digits) of the setting format at the time of horizontal writing are interchanged and read. Next, when the vertical cursor flag is switched from ON to OFF, the RAM 5
The start position of the vertically written document temporarily stored therein is cleared (step A5).

When a character is input in this state, it is detected in step A6 that the vertical cursor flag is ON. Then, the process proceeds to step A7, and it is checked whether it is immediately after the flag is turned on. Now, when the first character is entered immediately after operating the input direction temporary change key K,
The current text cursor position is saved in the RAM 5 as the start position of the vertically written document (step A8). Then, the input character is set in the input buffer 5-1 and an input process for displaying and outputting the character at the position of the text cursor is performed (step A9).

This input processing is executed according to the flowchart shown in FIG. First, it is checked whether there is a horizontal writing character on the right side of the current cursor position (step B
1). Now, as shown in FIG. 7B, since there is no horizontal writing character on the right side of the current cursor position, the process proceeds to step B3, where the input character "B" is set in the input buffer 5-1 and Display output is performed at the current cursor position (see FIG. 7B).

Then, in step A10 in FIG. 4, it is checked whether the line is the end of the vertical writing. If it is not the end of the line, the process advances to step A11 to move the cursor vertically (downward) by one character based on the format. . Then, steps A18 to A20 are executed in response to an operation such as conversion / confirmation,
In this case, since the vertical cursor flag is turned on, an identification code indicating vertical writing is added to the confirmed character code and stored in the input buffer 5-1. That is, as shown in FIG. 3, a vertical writing code is added to the vertical writing head character “B”. Similarly, "ji" is input as the next character, but in this case, since it is not immediately after turning on the vertical cursor flag, step A8 is skipped and the process proceeds to step A9. In this case, the input process shown in FIG. 6 is executed. However, as shown in FIG. 7B, “venue” exists as a horizontal writing character on the right side of the current cursor position. A space is secured by shifting one character line to the right by one character. Then, the input character "ji" is set in the input buffer 5-1 and displayed and output at the position of the text cursor (step B3). Then, steps A18 to A20 are executed by the confirming operation, and the vertical writing code is added to the input character "J" and stored in the document memory 5-2. Hereinafter, the same operation is executed each time one character is input. As a result, as shown in FIG. 7B, the vertically written character string “business show” is input to the left side of the horizontally written document.

Although FIG. 7 shows the case where one line of a vertically written character string is input, the line feed key is operated when inputting a plurality of lines. Then, if the vertical cursor flag is turned on (step A15), the start position of the vertical writing document saved in the RAM 5 is read out, and at the start position (column position) and next to the line currently input. The cursor is moved to the line position of (step A16). FIG. 8 shows the moving state of the cursor in this case. Note that step A16 is also executed when it is detected in step A10 that the line is the end of vertical writing (in case of automatic line feed). After inputting a vertical document in this way,
When the input direction temporary switching key K is operated again, the vertical cursor flag is turned off (step A3), and the horizontal writing format set in the format memory 7 is read (step A4). Then, the start position of the vertically written document is cleared (step A5), and hence, thereafter, all the input characters are input horizontally.

Next, the operation of editing a document in which a vertically written document is partially inserted in the horizontally written format will be described with reference to the flowchart shown in FIG. First, when character insertion is designated, it is checked whether or not the vertical cursor flag is turned on (step A21). Now, it is assumed that the cursor is positioned at the character insertion position of the vertical writing document and the input direction temporary switching key K is operated. Then, the process proceeds to step A22, where the character input at the current cursor position is inserted and the vertical writing code is added to this character code. If the original character input at the cursor position is a vertical writing character, the vertical character string that follows is moved downward by one character. on the other hand,
Even if the input direction temporary changeover key K is not operated and the vertical cursor flag remains OFF, if the vertical writing code is added to the character code at the cursor position (step A23), the above-mentioned one character Insertion process (step A2
2) is executed.

On the other hand, if the insertion of characters into the horizontally written document is designated, that is, if the vertical cursor flag is OFF (step A21) and no vertical writing code is added to the character at the cursor position (step A23). , One character is inserted in the horizontal writing direction as usual (step A2).
4). Here, when shifting the character string after the inserted character to the right by one character, if there is a character with a vertical writing code, the vertical writing character is not shifted and only the horizontal writing character string is shifted.

Next, when the character deletion is designated, the process proceeds to step A25, and it is checked whether the vertical cursor flag is ON. Now, assuming that the cursor is positioned at the character deletion position of the vertically written document and the input direction temporary switching key K is operated, the process proceeds to step A26, and the character at the cursor position is deleted. In this case, if the character input below the cursor position is a vertically written character, the vertically written character string that follows the character is moved up by one character. on the other hand,
Even if the input direction temporary switching key K is not operated and the vertical cursor flag remains OFF, if the vertical writing code is added to the character code at the cursor position (step A27), the above-mentioned one character Deletion processing (step A2
6) is executed. On the other hand, when the character deletion to the horizontally written document is designated (N in steps A25 and A27)
O), one character is deleted in the horizontal writing direction as usual (step A28). Here, when shifting the character string after the deleted character by one character to the left, if there is a vertically written character, this character is not shifted, as in the case of character insertion. It should be noted that even in copying, moving back space, etc., basically, it is performed for each vertically written document similarly to the above-mentioned editing processing.

As described above, in this embodiment, when a vertically written document is partially input in the horizontally written document, the input direction temporary switching key K is used without changing the setting format as horizontally written.
You can temporarily change the character input direction to vertical by simply operating. In this case, since a space for at least one character is inserted between the vertically written document and the horizontally written document, it is possible to easily identify the horizontally and vertically written documents. Further, in the case where a vertically-written document is mixed in a horizontally-written document, when the document editing is instructed, the editing direction can be changed to the vertically-written mode without changing the setting format as horizontally-written. In this embodiment, since the vertical writing code is added to the vertical writing characters at the time of inputting the document, the document memory 5 is not required to operate the input direction temporary switching key K at the time of editing the vertical writing document. The vertical writing document can be edited by referring to the contents of -2. However, if the input direction temporary switching key K is operated, the vertical writing document is directly edited without referring to the contents of the document memory 5-2. Is possible.

In the above embodiment, the case of inputting the vertical writing document in the left margin portion of the horizontal writing document has been described, but in the case of inputting the vertical writing document in the right margin portion of the horizontal writing document,
It is executed in the same manner as the flowchart shown in FIG. 4, but in this case, in the flowchart of FIG. 6, it is checked whether or not there is a horizontal writing character on the left side of the current cursor position. You can shift the space by 1 character to secure a space. Further, although the above example shows the case of inputting the vertical writing document into a part of the horizontal writing document, conversely, the case of inputting the horizontal writing document in the vertical writing document is basically the same as the above. Is the same as. In this case, the vertical cursor flag may be changed to the horizontal cursor flag, and the corresponding processing may be adapted to vertical writing and horizontal writing. Further, in the above embodiment, the vertical writing code is added to the character code and stored in the document memory 5-2 when the vertical writing document is input. However, the vertical writing code may not be added to the character code. The input direction temporary switching key K may be operated to change the editing direction to vertical writing.

In the above embodiment, horizontal writing and vertical writing are taken as examples of the character string input direction, but diagonal writing may also be used. By obliquely writing in this way, the title character string can be emphasized as a special effect. For example, if a title character string such as V-shape or W-shape is input, it becomes more effective. Further, in the above embodiment, the temporary change of the input direction is designated by the key operation, but it may be automatically changed. For example, the following method may be used as a method of automatically determining the vertical writing from the horizontal writing and changing the direction to the vertical writing. When the cursor is moved directly below the character input this time and the character is input at the position of the cursor, it may be determined to be vertical writing input and the subsequent character input direction may be changed to vertical writing. When converting the kana-kanji, for example, when the down cursor key is operated, the converted character string may be displayed vertically and the return key may be used to input vertically. In this case, subsequent input character strings may be changed to vertical writing. Alternatively, the peripheral area of the input character may be checked, and if the empty area in which no character is input is vertically long, it may be changed to the vertical writing direction. Further, in the above embodiment, the cursor shape is a square, but the cursor shape may be changed by horizontal writing or vertical writing.

[0021]

According to the present invention, the setting format is changed, for example, when a vertically written document is partially input in a horizontally written document or when a horizontally written document is partially input in a vertically written document. You can temporarily change the character string input direction to any direction without having to do this, and, for example, when a vertical writing document is mixed in a horizontal writing document or when a horizontal writing document is mixed in a vertical writing document. Moreover, since the character string editing direction can be temporarily changed to an arbitrary direction without changing the setting format, the operability can be significantly improved as compared with the conventional case.
