DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device for processing a character string composed of a plurality of characters.

[0002]

2. Description of the Related Art In a conventional word processor, 1
It was possible to rotate the characters entered once per character.
That is, by performing a character rotation instruction at the position where a plurality of characters are arranged on the document and performing the character rotation for each character, a document as shown in FIG. 7, for example, could be created.

[0003]

However, such a rotation operation is conventionally performed in units of one character, and when there are many character strings to be rotated, the operation becomes difficult. I was Therefore, for example, in order to obtain a character string form in which a character string composed of a plurality of characters is obtained by rotating individual characters included in the character string in character units without rotating the character string arrangement direction, the character string It is necessary for the operator to perform a rotation designation operation for each character in the row, which is a serious operation. In addition, in the related art, the actual character to be rotated is set to be immediately rotated by the rotation designation operation. Therefore, when an incorrect rotation is performed, it is necessary to perform a correction operation each time. In some cases, the operation was troublesome. An object of the present invention is to make it possible to use a character string that has already been input and displayed, change the character string to a desired display position, and output it in a desired output form.

[0004]

The means of the present invention are as follows. A document storage unit for storing document data including a plurality of characters; and a first unit for designating desired character string data in the document data as a character string to be moved or copied.
A plurality of output modes for simultaneously specifying the character array rotation state and the character rotation state such as rotation / non-rotation of individual characters at the time of the above specification. Sample display control means for displaying a sample character string image when a character string is output in its output form, for each output form, and among the plurality of output forms,
Selecting means for arbitrarily selecting a desired output form; second specifying means for specifying a desired position in the document data as a destination or destination of the specified character string data; and a specified character string When moving or copying the data to the specified destination or copy destination, based on the output form selected by the selection means, the character string data is arranged in an array rotation state determined by the output form, And output control means for controlling output by rotating / non-rotating each character included in the character string data in a character rotation state determined by the output form in units of one character.

[0005]

The operation of the means of the present invention is as follows. The desired character string data in the document data is specified as a character string to be moved or copied. At this time, the character string arrangement state and the character rotation state such as rotation / non-rotation of individual characters are specified. For each of a plurality of output modes specified at the same time, a sample character string image when a common predetermined character string prepared in advance is output in the output mode is displayed for each output mode. And, from among the plurality of output forms,
A desired output form is arbitrarily selected, and a desired position in the document data is specified as a position to which the specified character string data is moved or copied. Then, when moving or copying the specified character string data to the specified movement destination or copy destination position, the character string data is determined based on the output form based on the selected output form. And each character included in the character string data is rotated / non-rotated in units of one character in a character rotation state determined by the output form and output controlled. Therefore, when moving or copying a desired character string in the document data, a plurality of output forms are prepared in advance that simultaneously specify the arrangement rotation state of the character string data and the character rotation state of each character included in the character string data. The character string data to be moved or copied can be immediately converted to an output form according to a desired arrangement rotation state and a character rotation state and output by simply selecting a desired output form from the above. Can be
When selecting the output form, a sample character string image when a common predetermined character string is output in the output form corresponding to each of the plurality of output forms is displayed for each output form. Prior to the actual arrangement of the desired character string, the output image is confirmed on the display screen, and the character string arrangement can be output without error.

1 to 7 show an embodiment of the present invention.
This will be described with reference to FIG. Configuration FIG. 1 is a configuration diagram of a document editing processing device according to an embodiment. This document editing processing device performs various processes such as kana-kanji conversion under the control of the CPU 2 under the control of the CPU 2 on character data input by the key input unit 1, and stores the processing results and the like as document data in the document memory 3. Processing such as storage, display on the display unit 4, printing by the printing unit 5, and the like are performed.
By operating a predetermined key of the key input unit 1, various types of document editing processes such as moving and copying are performed on the character data strings stored in the document memory 3. The key input unit 1 includes, in addition to a character key 1A for inputting various character data, a movement key 1B for instructing a movement process, a copy key 1C for instructing a copy process, and a cursor movement key 1D for moving a cursor. Have. When each key of the key input unit 1 is operated, a code such as a corresponding character code is generated.
2 is input. Therefore, character data is stored in the document memory 3 and the like in the form of character codes (including symbol codes). Therefore, when displaying and printing the contents of the document memory 3, the CPU 2 reads out the corresponding character pattern data stored in advance in the character pattern memory (character generator CG) 6 and outputs it to the display unit 4 and the printing unit 5. . Then, the display unit 4 and the printing unit 5 display a display signal corresponding to the input character pattern data,
Generate print signal, display and print.

As shown in FIG. 3, the character data is composed of 2 bytes, of which 14 bits are used as a character code and 2 bits are used as rotation bits. This rotation bit indicates the direction of rotation of the character indicated by the corresponding character code at the time of output.
“0” is normal upward, “01” is rightward (90 ° rotation direction), “10” is downward (180 ° rotation direction),
“11” indicates leftward (−90 ° rotation direction). When outputting the character pattern data corresponding to the character code to the display unit 4 and the printing unit 5 as described above, the CPU 2 outputs the character pattern data after performing a rotation process according to the content of the rotation bit. .

When the move key 1B or the copy key 1C is operated, a message for guiding the user to specify a character data string to be moved or copied is displayed. When the target character data string is designated by the cursor movement key 1D according to the message display, the designated character data string is stored in the character buffer 7. Thereafter, for example, an output form example in which the arrangement direction of the character strings is from top to bottom and the direction (rotation direction) of each character is right is displayed together with the form number.

[0009] Further, a message for designating a moving destination or a copy destination is displayed. Then, after looking at this guidance display and inputting the form No. of the desired output form, each rotation bit in the character data string specified in the character buffer 7 changes according to the rotation direction corresponding to the form of the form number. Changed. When a destination or a copy destination is designated, the character data string in the character buffer 7 whose rotation bit has been changed is stored in the document memory 3 with the designated destination or the copy destination as a starting point. The arrangement is changed in the arrangement direction corresponding to the form. In such moving and copying processes, the registers x ₁ , y ₁ , x ₂ , y ₂ , x
_{0, y 0, X, Y} , and output form flag F is used.

[0010] Operation will now be described with reference to FIGS. 3-7 the movement processing operation of this embodiment. When the movement key 1B is operated, the CPU
2 is a display unit 4 according to a predetermined program.
Is displayed (step S1 in FIG. 3). Therefore, when the cursor is moved to the start position by operating the cursor movement key 1D in order to specify the start point of the character string to be moved in accordance with this message, the x component and the y component of the start point coordinates A are respectively stored in the register x. _1, and stores it in the y ₁ (step S2). Next, a message "How far?" Is displayed on the display unit 4 (step S3). Therefore, when the cursor is moved to the end position by operating the cursor movement key 1D to specify the end point of the character string to be moved in accordance with this message, the x component and the y component of the end point coordinate B are respectively registered in the register. x _2, and stores it in the y ₂ (step S4). Next, the number of digits of the character data string to be moved, in order to calculate the number of rows, {(the content of register x ₂₎ - (contents of register x ₁₎ +1},
{(The contents of register y ₂₎ - (contents of register y ₁₎ +
1｝, and the result of the operation is
The values are stored in registers x ₀ and y ₀ (step S5). Then, the character data strings within the range defined by the start point coordinates A and the end point coordinates B are read from the document memory 3 and sequentially stored in the character buffer 7 (step S6). At this time, as shown in FIG. 5B, when the start point (“A”) and the end point (“K”) are not on the same line, and the y components of the start point coordinates A and the end point coordinates B are different. The character data string within the range of a rectangle having the start point coordinates A and the end point coordinates B as diagonal points is read from the document memory 3 and stored in the character buffer 7.

Next, an output form guidance display as shown in FIG. 5A is performed (step S7). In this guidance display, the eight output forms are displayed in correspondence with the form number using the character string “ABC” as an example, and a message “Please specify the number of the output form” is also displayed. Will be For example, in the case of the form number "6", the output direction is such that the arrangement direction of the character string is such that digits proceed from top to bottom, lines proceed from right to left, and the direction of each character is upward. The form is shown. That is, for example, when the form number “6” is specified for the character data string as shown in D1 of FIG. 5B, the character data string is changed and output as shown in D2. I have. In the form number “7”, the output direction is such that the arrangement direction of the character string is such that digits proceed from right to left, lines proceed from bottom to top, and the direction of each character is right. The form is shown. That is, for example, when the form number “7” is specified for the character data string as shown in D3 of FIG. 5C, it is changed and output as shown in D4. I have. Regarding the arrangement direction of the character strings, the form numbers “1” and “5”, “2” and “6”, “3” and “7”, and “4” and “8” are the same. Regarding the direction of the characters, the form numbers "1" and "6", "2" and "7", "3" and "8", and "4" and "5" are the same.

When a desired form number is designated and input while looking at the output form guidance display, the value of the number is set in the output form flag F (step S8). Next, a message "Where?" Is displayed (step S9). Then, when the destination is designated by the cursor according to the message, x of the designated destination C
The component and the y component are stored in registers X and Y, respectively (step S10). Then, the contents of the output mode flag F are determined (step S11). As a result, when the output form flag F is the form number “2” or “7”, all the character data strings in the character buffer 7 are set to + 90 ° so that each character of the character string is turned rightward. The rotation bit “01” is set (step S12), and the process proceeds to step S15. When the output mode flag F is the mode number “3” or “8”, all the character data strings in the character buffer 7 are set to + 180 ° so that each character of the character string is directed downward. The rotation bit “10” is set (step S13), and the process proceeds to step S15. When the output form flag F is the form number “4” or “5”, all character data strings in the character buffer 7 are set to −90 ° in order to make each character of the character string face left. Is set (step S14), and the process proceeds to step S15. When the form number is "1" or "5",
Since there is no need to change the direction of each character of the character string, the process immediately proceeds to step S15.

In step S15, the character data string within the range between the start point A and the end point B is deleted from the document memory 3. Then, a movement process is performed for each output mode flag (step S16). When the mode number “1” or “5” is set in the output mode flag F, the normal moving process without changing the arrangement direction as shown in FIG. a) Steps S16-11 to S16-
Step 17 is performed. That is, “0” is stored in the register β (step S16-11), and “0” is stored in the register α (step S16-12). Next, the document memory 3
In response to this, one character data in the character buffer 7 is sequentially arranged from the top, {content of register X) + (content of register α),
(Contents of register Y + contents of register β) are copied to a position in the document memory 3 corresponding to the coordinates of｝ (step S1)
6-13). In the process of step S16-13, since the registers α and β are both “0” at the first time, the coordinates of the copy destination are the same as the contents of the registers X and Y, and the first coordinates shown in FIG. The character (character code) “a” to be copied the second time is the designated destination C
Copied at position (X, Y). However, when the form number “5” is designated, the form number −90 ° rotation bit “11” is set.
A rotation process of -90 ° is performed by the CPU 1, and FIG.

Next, the register contents of β can register y number of lines of the character data string to be moved in the ₀ (in this example "2") and decides whether the equal (step S16-17). As a result, if not equal, the process returns to step S16-12 to clear the contents of the register α, and performs the processing from step S16-13. Therefore, when copying the next "O" after the "E", the contents of the register β are stored in the step S16-16.

At step 16-14, the content of the register α is set to "1", and the process returns to step S16-13 via step S16-15. As a result, the copy destination coordinates of “ka” are on the right side of “o”.

When the form number "2" or "6" is set in the output form flag F, as shown in FIG. 6 (e), the digit advances from top to bottom and the line moves from right to left. In order to move in an output form that proceeds to the left, the processing of steps S16-21 to S16-27 in FIG. 4B is performed. That is, "0" is stored in the register β (step S16-
21), “0” is stored in the register α (step S16)
-22). Next, the character buffer 7 is stored in the document memory 3.
In the document memory 3 corresponding to the coordinates of {contents of register X)-(contents of register α), (contents of register Y + contents of register β) in order from the top ( Step S16-23). In the process of step S16-23, since the registers α and β are both “0” at the first time, the coordinates of the copy destination are the same as the contents of the registers X and Y, and the character ( The character code "A" is copied to the position of the designated destination C (X, Y). However, in the case of the form number “2”, since the rotation bit “01” of + 90 ° is set, the CPU 1 displays + 90 ° at the time of display.
° rotation processing is performed, and as shown in FIG.

Next, the register contents of α is, the register y number of lines of the character data string to be moved in the ₀ (in this example "2") and decides whether the equal (step S16-27). As a result, if they are not equal, the process returns to step S16-22 to clear the contents of the register β, and performs the processing from step S16-23. Therefore, when copying the next "O" after the "E", the contents of the register α are stored in the step S16-26.

16-32.). Next, in the document memory 3, one character data in the character buffer 7 is sequentially arranged from the head, {contents of register X) − (contents of register α), (contents of register Y−).
(Contents of register β) is copied to the position in the document memory 3 corresponding to the coordinate of｝ (step S16-33). In the processing of steps S16-33, since the registers α and β are both “0” at the first time, the coordinates of the copy destination are the same as the contents of the registers X and Y, and the character ( The character code "A" is copied to the position of the designated destination C (X, Y). However, in the case of the mode number “3”, since the rotation bit “10” of + 180 ° is set, the CPU 1 displays +1
The rotation process of 80 ° is performed, and the rotation is directed downward as shown in FIG. In the case of the form number “7”, +
Since a 90 ° rotation bit is set, a + 90 ° rotation process is performed at the time of display, and the display is turned rightward.

Next, the contents of register alpha "1" incremented (step S16-34), the contents of the register alpha is, registers x number of digits of the character data string to be moved in the ₀ (in the above example "4 ") Is determined (step S16-35). As a result, if not equal, the process returns to step S16-33. Second
In the second time S16-33, the contents of the register α
In 16-34, “1” is incremented by “1”.
So the second copy target character "i"

Next, the register contents of α is, the register y number of lines of the character data string to be moved in the ₀ (in this example "2") and decides whether the equal (step S16-47). As a result, if not equal, the process returns to step S16-42 to clear the contents of the register β, and performs the processing from step S16-43. Therefore, when copying the next "O" after the "E", the contents of the register α are stored in the step S16-46.
In step S16-42, the content of the register β is cleared to "0". As a result, the copy destination coordinates of “O” are on the right side of “A” as shown in FIG. To copy the next "?"
At step 16-44, the content of the register β is set to "1", and the process returns to step S16-43 via step S16-45. As a result, the copy destination coordinates of “ka” are above “o”.

As described above, according to this embodiment, the character string can be moved with its original arrangement changed. Moreover, the change designation of the arrangement form may be performed by the form number according to the guidance display, and the change designation operation is simple. When it is desired to output the “development degree” of the arrangement form as shown in FIG. 7 using the above-described movement processing,
The digit proceeds from left to right as usual, and each character is input with "expansion degree" in an upward direction, and the form number "2" is designated as the output form of this "expansion degree", and the destination is shown in FIG. "Exhibition"
You can specify the position of. Similarly, when it is desired to output “patentability” and “technical power” in the arrangement form as shown in FIG. 7, “patentability” and “technical power” are input to the arbitrary positions as usual, respectively. The output form of “patentability”, the form number “3” as the destination, and the position of “special” in FIG. 7 are designated. The output form of “technical power”, the form number “4” as the destination, and “ What is necessary is just to specify the position of "skill".

As described above, without performing the complicated operation of individually designating the output position of each character and instructing each character individually to rotate as in the prior art, With a simple operation, it is possible to output character strings in various arrangement forms. Note that the present invention is not limited to the above-described embodiment, and it is also possible to perform copying in a form in which the original arrangement of character strings is changed, for example.
This case can be realized by an algorithm substantially similar to that shown in FIGS. That is, in this case, FIG.
The erasing process in step S15 may be omitted.

[0026]

According to the present invention, when moving or copying a desired character string in document data, the arrangement rotation state of the character string data and the character rotation state of each character included in the character string data are simultaneously performed. Since a plurality of output forms to be specified are prepared in advance, the character string data to be moved or copied can be output in a desired arrangement rotation state and character rotation state by simply selecting a desired output form from these. It can be immediately converted to a form and output. In addition, when selecting the output mode, corresponding to each of the plurality of output modes,
A sample character string image when a common predetermined character string is output in the output form is displayed for each output form, so that the output image is displayed on the display screen prior to the actual arrangement of the desired character string. After confirming the above, it is possible to output a string array without errors.
