Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device used in a word processor or the like.

[0002]

2. Description of the Related Art Conventionally, word processors that perform display control shown in FIGS. 11 to 13 are known.
That is, FIG. 11 is an image diagram of a text, and the text 50 stores illustration data 52 together with document data 51 composed of character data and line feed data. Each line of the text 50 has 10 columns, and one character of document data 51 is stored in each column of each line. Further, in this example, the illustration data 52 has a structure of 4 rows × 4 columns and occupies a rectangular area whose diagonal points are the 2nd row and 1st column and the 5th row and 4th column.

When the text 50 is displayed on the one-line display LCD, as shown in FIG. 12, if the display width of the LCD 53 is 10 characters which is the same as the character string of the text 50, the line of the illustration data 52 is displayed. The entire line including the minutes can be displayed with the cursor 54. However, when the width of the LCD 55 is 6 characters smaller than the character string of the text 50 as shown in FIG.
It is impossible to display it on the CD 55, and only the right six characters from the position of the cursor 54 will be displayed on the LCD 55.

That is, as shown in FIG. 13 (1), when the cursor 54 is moved to the second row and fifth column, six characters from "C" to the line feed mark of the relevant row are displayed. As shown in FIG. 2B, when the cursor 54 is moved to the 2nd row and the 4th column, 6 characters from the illustration portion 2-4 at the 2nd row and the 4th column of the illustration data 52 to “part” are displayed. To be done. Further, as shown in (5) of the figure, when the cursor 54 is moved to the second row and the first column, the illustration data 52
2 rows, 1 column, 2 columns, 3 columns, 4 columns of illustration parts 2-
Six characters of 1, 2-2, 2-3, 2-4 and "C" and "D" will be displayed.

[0005]

As described above, the LCD 55 having a width smaller than the character string of the text 50 in the related art.
When the cursor 54 is moved to the left when
As shown in 3 (2) to 3 (5), the parts of the line of the illustration data 52 are sequentially displayed as the cursor 54 moves. However, since the illustration data 52 stored on the text 50 cannot be edited in the edit mode, it is meaningless to sequentially display each part of the illustration data 52 or move the cursor 54 to each part. is there. Therefore, the meaningless movement of the cursor 54 onto the illustration data 52 composed of a plurality of rows and columns causes
The cursor 5 is quickly moved to the editable document data 51, which causes the movement of the cursor to the document data 51 to be delayed.
It becomes difficult to move 4. Moreover, the width of the illustration data 52 occupies most or all of the display width of the LCD 53, and the document data 5 is displayed on the display line of the LCD 53.
When 1 and the illustration data 52 are mixed,
It becomes more difficult to understand the layout of the document data 51 and the illustration data 52 in one line which is partially displayed, which makes the editing of the document inconvenient.

The present invention has been made in view of the conventional problems as described above, and aims to speed up the movement of the cursor on the document data, and to lay out the document data and the image data such as illustrations during the document editing. It is an object of the present invention to provide a display control device in which the display is easy to see.

[0007]

In order to solve the above-mentioned problems, in a display device according to the present invention, display means, input means for inputting image data and document data, and input from this input means. The gist of the present invention is that the image data is replaced with a symbol whose size in the row direction is made up of one character, and the image data is displayed on the display unit together with the document data.

[0008]

In the above structure, the display control means replaces the image data stored in the storage means with a symbol having a size of one character in the row direction and causes the display means to display the image data. Therefore, even if the image data has a size that extends over a plurality of rows and a plurality of columns, only one column of symbols corresponding to the image data is displayed on the display means. Therefore, if the cursor is moved to the left or right by one character from the state where the cursor is on the symbol, the cursor immediately arrives on the document data. Further, since the image data is displayed with the symbols compressed in the row direction, the display of the document data displayed in the same row is redundant, and the layout relationship between the image data and the document data is displayed.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, this embodiment is an application of the present invention to a word processor.

Is the image data of the illustrations of different types of patterns, which are composed of 4 rows x 4 columns for the standard character size.
It is stored in correspondence with codes 01 to N. The kana-kanji conversion table 92 stores kanji codes corresponding to kana codes. Therefore, the CPU
7 refers to this kana-kanji table 92 to convert the kana code input from the character / numerical key 7 into a kanji code in response to the operation of a conversion key (not shown), and this conversion is performed. The character corresponding to the Kanji code or the unconverted kana code is read from the character generator 14. It should be noted that the character generator 14 stores not only kana and kanji characters, but also symbol characters for displaying the above-described 4-row × 4-column illustration image data as symbols for one character. .

The RAM 10 includes a print data memory 10
1, a document management buffer 102, an image information memory 103,
A character data memory 104, a text data memory 105, an image memory 106, and a pointer 107 are provided. The print data memory 101 stores the character to be printed, and the CPU 8 sequentially reads the data corresponding to one line of the character stored in the print data memory 101 and prints the one line. 12 is sequentially instructed. In accordance with this instruction, the print control unit 12 controls the motor 15 and the print head 16 that move the carriage on which the print head 16 is mounted and that drives the paper feed mechanism, whereby the characters are sequentially printed line by line on a predetermined paper. Alternatively, the illustration is printed.

As shown in FIG. 2, the document management buffer 102 stores an area 102a for storing the number of lines of a document, "1" when image data exists in the line, and "0" when image data does not exist. It is composed of a storage area 102b for the flag F, an area 102c for storing the number of characters that can be input in the line, and an area 102d for storing the number of input characters, which is the number of input characters. Therefore, in the present embodiment in which the maximum number of input characters in one line is “10”, in the case of the text shown in the image diagram of FIG. 4, the document management buffer 102 stores the area 102 of lines 1 to 4 as shown in FIG.
F = 1 is stored in b. Further, since the image data has 4 rows × 4 columns as described above, 10−4 = 6
Thus, "6" is stored as the number of characters that can be input in the areas 104c of the first to fourth lines. Also, the fifth line is
In addition to F = 0, the maximum number of input characters "10" is stored as the number of inputtable characters. In the area 102d of the document management buffer 102, 1 to
The number of characters "6, 6, 6, 6, 9" at the border of the five lines is stored as the number of input characters. Furthermore, area 102
In e, the start position of the character data in each line of the text is stored in rows / columns.

As shown in FIG. 3, the image information memory 103 comprises an area 103a for storing the type of image, an area 103b for storing the size of the image, and an area 103c for storing the insertion position of the image. . Area 10
3a stores the type of image with the code stored in the image data memory 91, and the area 103b
The image size is stored as "row x column". In the area 103c, the entire image insertion position is
Therefore, in the case of the text illustrated in FIG. 4, 16 pieces of row / column data are stored in the area 103c, such as 1/1, 1/2 ... 4/3, 4/4. The Rukoto.

Further, the character data memory 104 sequentially stores the data of the character string input from the key input unit 1, and the sentence data memory 105 includes all the kanji-converted character data and the unconverted character data. Data, that is, all the character data (sentence data) excluding the illustration in the text is stored. Further, the image memory 106
Of the image data stored in the image data memory 91 stores the image data of any one of the selected patterns, and the pointer 107 indicates the value of the character data stored in the character data memory 104. Specify the data position.

Next, the operation of this embodiment having the above configuration will be described with reference to the flow chart and the like. That is, when the new document creation mode is set by operating a function key (not shown), the CPU 8 executes the control according to the flow shown in FIG. 5, and first determines whether or not the illustration key 6 is turned on. Is determined (step A1). If the illustration key 6 is not turned on, it is determined whether or not the character key in the character / numerical key 7 is turned on (step A8). If the character key is not also turned on, step A1 → Repeat the loop of A8 → A1,
Maintain a standby state.

When the illustration key 6 is operated to set the image data input mode, the illustration input condition is set (step A2). This step A2
The input condition setting of the illustration executed in is as follows (1)
The content of the setting process is (2). (1) Image Type Setting Processing As described above, the image data memory 91 of the ROM 9 has
Image data of a plurality of types of different illustrations composed of 4 rows x 4 columns for the standard character size are 0001 to N.
It is stored in correspondence with the codes up to. Then, when the code corresponding to the desired picture is numerically input by operating the character / numerical key 7 and the picture is designated, the code corresponding to the picture is displayed in the area 103a of the image information memory 103 shown in FIG. Remembered. (2) Image Insertion Position Setting Processing The cursor insertion keys 2 to 5 are operated to specify the image insertion position, and the execute key is operated to specify the insertion position. That is, the text example shown in FIG. 4 is a case where the cursor is positioned at the 1st row and the 1st column and the execution key is operated. When the image insertion position is designated in this way, the size of the image is stored in the area 103b of the image information memory 103 in "row x column" and the area 103b is also stored.
The entire insertion position of the image is stored in c with "row / column".

When the illustration input conditions are set in this manner, it is determined in the next step A3 whether or not the insertion position is appropriate. That is, in this embodiment,
As shown in FIG. 4, a maximum of 10 characters of standard size can be entered in one line of text, and the pattern is 4 lines x
Since the size is 4 columns, the illustration cannot be inserted at the end of the line or the end of the page. Therefore, in this case, the error display data is transferred to the display memory 11, and the liquid crystal display unit 18
Is displayed on the screen (step A6). Subsequently, in step A2 described above, the area 1 of the image information memory 103 is
Each data stored in 03a, 103b, 103c is cleared (step A7). After that, the liquid crystal display 18
Is displayed on the screen, and it is determined whether or not to continue the input based on a predetermined key operation on the key input unit 1 (step A12). If the input is to be continued, the process returns. , If you do not continue to enter, go to the end.

On the other hand, if the result of determination in step A3 is that the insertion position is appropriate, a flag is set in the relevant line of the document management buffer 102 (step A4), and then a symbol is displayed on the display screen (step A4). A5). That is, as shown in FIG. 6 (1), with the cursor C in the 1st row and 1st column, the illustration key 6 is operated to operate the numeral key of "1", and then the FIG. As shown in FIG. 3, if the execution key is operated, the input condition setting in step A2 causes "0001" to be stored in each area 103a to 103c of the image information memory 103 as the type of image. , As the size of the image "4 ×
4 "is stored, and the image insertion position is 1 /
16 pieces of position data 1 to 4/4 are stored.

Further, since this insertion position is proper, as shown in FIG. 2, by the processing of step A4, F is added to lines 1 to 4 of the area 102b of the document management buffer 102.
= 1 is set. Furthermore, since the number of characters used for illustration in each line of 1 to 4 is "4", 10-4
= 6, and the area 102c corresponding to the first to fourth rows stores "6" as the number of characters that can be input. Further, in the subsequent step A5, the character corresponding to the illustration of code 0001 is read from the character generator 14 and transferred to the display memory 11.
As a result, as shown in FIG. 6B, the symbol S based on the character is displayed in the 1st row and 1st column of the liquid crystal display unit 18. As shown in the figure, the symbol S has a configuration in which characters of "illustration" are arranged in a rectangular frame having a size of one character.

On the other hand, in the flow of FIG. 5, when the character key is turned on, the process proceeds to steps A1 → A8 → A9 to determine whether or not there is an illustration in the display range. That is, if the state of the flag F stored in the area 102b of the document management buffer 102 is “1”, there is an illustration in the line, and this line also has the liquid crystal display unit 18
When it is displayed in, the illustration is in the display range. If there is an illustration in the display range, the process further proceeds from step A9 to step A11 to display both the symbol and the input character on the liquid crystal display unit 18.

That is, the symbol S is displayed in the first column of the liquid crystal display section 18 as shown in FIG. 6 (2) by the processing in step A5 described above. When the character keys "A" and "B" are turned on in this state, the input character data are stored in the character data memory 104 in the form of a corresponding code signal, and the "A" Since character data does not need to be converted, it is stored in the text data memory 105 as it is. At this time, in the document management buffer 102, the area 1 is input every time the character data “A” is input.
The data of the number of input characters is stored in 02d, and the position of the input first character data "A" is stored in the area 102e of the document management buffer 102 in rows and columns, for example, 1/5. . Then, the characters corresponding to the character data of "A" and "B" are read from the character generator 14 and transferred to the display memory 11, but the area 102 of the document management buffer 102 is read.
From the information of e and the area 103c of the image information memory 103, in the first line of the document, character data (character data of "A") is located following the illustration, so C
The PU 8 transfers the corresponding character data to the display memory 11 so that the character data of A is displayed in the first row and the second column of the symbol S displayed in the first row and the first column of the liquid crystal display unit 18. In this manner, the character data “B” is also subjected to the same display processing, whereby the characters “A” and “B” are displayed on the liquid crystal display unit 18 together with the symbol S, as shown in FIG. It Furthermore, as shown in FIG.
When the conversion key and the execution key are operated by key operation of “i”, “sa”, “n” and “ki”, the converted character data of “calculator” is stored in the text data memory 105,
The cursor C is moved to the right end by being sequentially displayed by the processing of step A11. At this time, since the liquid crystal display unit 18 has only an area capable of displaying a maximum of 6 characters,
The symbol S is scrolled out of the display area, and is displayed in FIG.
As shown in, the display state of only the characters "AB computer" is displayed. When there is no illustration in the display range and only characters are input, as in the case of inputting the fifth line of the text shown in FIG. 4, steps A9 to A10 are entered.
Then, the input character is displayed within a maximum of 6 characters.

Further, after the document is created as described above, when the edit mode is accompanied by correction, addition and deletion of the created document, the CPU 8 starts the control according to the flow shown in FIG. It is determined whether there is an illustration (step B1). That is, the position of the cursor is stored in the cursor counter 13 with the line and the column of the text, and the text content of the line where the cursor is located at that time is displayed on the liquid crystal display unit 18. Further, by referring to the state of the flag F stored in the area 102b of the document management buffer 102, it can be known whether or not there is an illustration in the line. Therefore, the CPU 8 determines whether or not there is an illustration in the display range by referring to the value of the line of the counter 13 and the value of the area 102b of the document management buffer 102 corresponding to the value of this line.

More specifically, in this example, the cursor C
Is in the first column of the liquid crystal display unit 18, and in the position corresponding to the first row and the first column in the text of FIG. 4, the value of the counter 13 is “row = 1, column = 1”. , RAM1
The pointer 107 within 0 indicates the data position of the character data memory 104 corresponding to the position of this cursor.
The area 102b of the document management buffer 102 is 1
The area corresponding to the row has the flag F = 1. Therefore, after checking the value of the line of the cursor counter 13, the area 10 of the document management buffer 102 corresponding to the value of this line is checked.
By confirming that F = 1 in 2b, it is possible to conclude that the illustration is within the 6 characters which is the display range.

When it is determined that there is an illustration in the display range, the process proceeds to step B2, and the position of the first column of the stored illustration is read from the area 103c of the image information memory 103 shown in FIG. 3 ( Step B2). Here, in the case of this example, the illustration occupies the positions from the 1st row and the 1st column to the 4th row and the 4th column.
/ 1 (1 row and 1 column) will be read. Next, the stored character data is read in the display range (step B
3). That is, the liquid crystal display unit 18 can display a maximum of 6 characters, and since the symbol S occupies 1 character, the remaining 5 characters are the display range. So CP
U8 is the area 10 on the first line of the document management buffer 102.
Input character number "6" and area 10 stored in 2d
After confirming the position 1/5 of the first character data of 2e, it is decided to read the data of 5 characters out of the 6 characters, and the data is read from the position indicated by the pointer 107 of the document data memory 105 to 5 positions.
Read the character data for a character.

Next, the symbol and character data are both displayed based on the read data (step B4). By the processing in step B4, as shown in FIG. 8 (1), data for 6 characters including the symbol S and the "AB calculator" is displayed on the liquid crystal display unit 18. After the display in step B4, it is determined whether or not the cursor is moved, that is, whether or not each of the movement keys 2 to 5 is operated (step B7). If they are operated, the process proceeds to step B1. To return. If there is no illustration in the display range as a result of the determination in step B1, the stored character data is read out in the display range (step B
5) Display the read character data (step B)
6). Therefore, on the text shown in FIG.
When the cursor is moved to the 5th row and the 1st column without an illustration, 6 characters of "word process" are displayed on the liquid crystal display unit 18.

On the other hand, the CPU 8 executes the control shown in FIG. 9 in response to the operation of each of the moving keys 2-5. That is, in accordance with the operation of the move keys 2 to 5, the cursor is moved in the direction indicated by the move keys 2 to 5 (step C1), and it is determined whether or not the subsequently operated keys are the left and right move keys 2 and 3. It is determined (step C2). If it is the left / right movement keys 2 and 3, it is further determined whether or not it is the right movement key 3 (step C3). If it is the right movement key 3, the previous cursor position is the symbol. It is determined whether or not it is above (step C4).

If it is on the symbol, it is judged whether or not the cursor is moved on the same line (step C5). If it is on the same line, the column counter of the cursor counter 13 is determined. Add "4" (Step C
6). Therefore, as shown in the upper part of FIG.
With the cursor C at the position of the symbol S in the first column,
If the right move key 3 is operated, the cursor C moves to the 1st row and 2nd column on the display as shown in the lower part of FIG.
As a result of the determination of all being YES, the counter display becomes "1 column 5 rows" by the process of step C6.

If the determination in step C5 is NO and the line is not in the same line, the line is moved to the first column in the next line. Therefore, the column counter of the cursor counter 13 is set to "1". (Step C7). Further, if the determination in step C4 is NO and the previous cursor position is not on the symbol, it means that the cursor has simply moved to the right between the characters, so "1" is added to the column counter of the cursor counter 13. (Step C8).

Further, when the determination in step C3 is NO and the left movement key 2 is operated, it is determined whether or not the current position of the cursor after movement is on the illustration (step C9). . If the result of this determination is on the illustration, "4" is subtracted from the column counter of the cursor counter 13 (step C10). Therefore, FIG. 10 (2)
As shown in the upper part of FIG. 7, if the left movement key 2 is operated in the state where the cursor C is at “E”, the symbol in the first column of the liquid crystal display unit 18 is processed by the processing according to the flow of FIG. S is displayed, the cursor C is displayed on the symbol S by the processing of step C1, and the counter display is changed from "4 rows and 5 columns" to "4 rows and 1 column".

If the determination in step C9 is NO and the current cursor position is not on the illustration,
It is determined whether or not the same row is moved (step C11). If the same row is moved, "1" is subtracted from the column counter.
If the determination in step C11 is NO and the line is not on the same line, the cursor is moved to the 10th column on the next line. Therefore, the column counter of the cursor counter 13 is set to "10". Is set (step C13).

On the other hand, if the result of determination in step C2 is that it is the up / down movement keys 4, 5 instead of the left / right movement keys 2, 3, the process proceeds from step C2 to step C14, and whether or not it is the up movement key 4. Determine whether. If it is the up move key 4, "1" is subtracted from the line counter of the cursor counter 13 (step C15), and if it is the down move key 5 instead of the up move key 4, the line counter is set to "1". ”
Is added (step C16). Then, the values of the row counter and the column counter of the cursor counter 13 set in the above respective steps are displayed on the liquid crystal display unit 18 (step C17). You can recognize if you are in a position.

When printing the created document data with illustrations, if a print key (not shown) is operated,
The document data stored in the document data memory 105 and the illustration data stored in the image memory 106 are stored in the print data memory 101 based on the management information of each document and illustration in the document management buffer 102 and the image information memory 103. Data is synthesized with. Then, the combined data is sent to the printer unit and printed on the print medium in the form as shown in FIG.

[0034]

As described above, according to the present invention, the image data is replaced with the symbol whose size in the row direction is one character, and is displayed on the display means together with the document data. Therefore, when the cursor is moved on the display means, unnecessary cursor movement on the uneditable image data is eliminated, and the cursor can be quickly moved to the document data. Further, according to the present invention, since the symbol representing the image data has a size in the row direction of one character regardless of the size of the image data, the document including the image data and the document data is displayed on the display means having a small size. Even when doing so, the layout display of both data becomes easy to see and the document editing work becomes easy. Further, according to the present invention, when the cursor moves between the symbol and the document data, the position display value of the cursor is changed according to the size of the image data replaced by the symbol. Therefore, even when the image data is replaced with the symbol and displayed, the cursor position on the text can be accurately recognized.
