It is composed of a cursor movement circuit 55, a cursor position determination circuit 5, a range determination circuit 57, and a text attribute change circuit 58.

Next, the functions of each of these components will be briefly explained.

The input control circuit 41 determines the next process to be performed based on the data input from the input device 1, and transmits the data and instructions to each corresponding circuit.

The kana-kanji dictionary area 42 is a part of the dictionary memory 24 described in FIG. 3, and is a dictionary area that stores dictionaries necessary for kana-kanji conversion.

The document text area 43 receives text data from the text editing circuit 48 and stores it.

The CG font area 44 is a part of the dictionary memory 24 described in FIG. 3, and is a character pattern storage area (character generator) that stores character patterns of characters in a predetermined typeface, such as Gothic or Mincho.

When receiving a conversion request from the input control circuit 41, the Kana-Kan conversion circuit 45 inputs the corresponding character data from the Kana-Kan dictionary area 42 and the text editing circuit 48, and performs Kana-Kan conversion processing.

If the character data received from the text display data creation circuit 49 has an attribute, the attribute data creation circuit 46 sends the font data of the character from the CG font area 44 and the enlarged data to the enlarged data creation circuit 47. Yoriuke takes it and processes the attributes.

The expanded data creation circuit 47 receives the attribute data from the attribute data creation circuit 4, creates expanded data, and outputs it to the attribute data creation circuit 46.

The text editing circuit 48 receives character data from the input control circuit 41 and stores the determined character data in the document text area 43 as text data.

The text display data creation circuit 4th is the CG font area 44. Font data is received from the attribute data creation circuit 46, character data is received from the text editing circuit 48, and attribute data of the font data is received from the attribute data search circuit 50, and text display data is created and displayed on the display device 2.

The attribute data search circuit 50 searches for attribute data for the font data of the text display data creation circuit 49 and passes it to the text display data creation circuit 4.

The attribute control circuit 51 adds an attribute such as enlargement inputted from the input control circuit 41 to each character code of the character or character string specified by the range specification circuit 57.

In other words, it functions as an extended attribute adding means.

The instruction string instruction display data creation circuit 52 creates instruction display data that indicates the enlarged size and position of the instruction string based on the coordinate data from the attribute control circuit 51 and causes the display device 2 to display the created instruction display data. In other words, it functions as an enlarged content instruction means.

The enlargement factor determination circuit 53 determines the enlargement factor based on the position data of the enlarged size indicating cursor inputted from the input control circuit 41 . Then, the numerical data is transferred to the attribute control circuit 51. The cursor position data is output to the enlargement magnification display data creation circuit 54 and to the cursor position determination circuit 5.

Note that the cursors in this embodiment include a character cursor that indicates the normal character input position, and a size indicating cursor that indicates the size after enlargement.

The range determining circuit 57 determines the range of characters or character strings to be enlarged based on input data from the input control circuit 41 and text data from the attribute control circuit 51. In other words, it functions as an enlargement target specifying means.

The text attribute changing circuit 58 changes the text attribute based on the text data from the attribute control circuit 51 and transfers the changed text data to the attribute control circuit 51.

An overview of the general functions of the part related to the enlargement control processing of the character string configured as described above will be explained.

The data input from the input device 1 is sent to the input control circuit 41.
The allocation is controlled according to the type of input data.

When character data is input, it is held as document text by the text editing circuit 48, and when there is a request for conversion of the character string, it is stored in the Kana-Kan dictionary area 4 by the Kana-Kan conversion circuit 45.
The conversion candidate is extracted from among the two. When the character string at that time is determined by the execution key or the like, it becomes document text and is stored in the document text area 43.

A document is created in this way, and at this time the text is stored as a character code as shown in FIG. 5(a). This character code is represented by one word, but various attribute codes can be attached to the characters in the document text, as shown in FIG. 2(b). For example, the attributes include white outline, double-width italic, underline, shading, and enlarged attributes.

Next, the attribute setting operation will be explained according to the flowchart of FIG. 4 and with reference to FIG. 6 and other figures.

First, among the input character strings, position the character cursor C1 at the beginning of the character string to which you want to add an attribute, and press the range specification key 15 shown in Figure 2. The current character cursor position is highlighted and becomes the starting point.

Next, the cursor is moved to the desired end point using the right movement key of the cursor movement key group 14.

Then, when the execution key 12 is pressed, the cursor position at that time becomes the end point, the character string between the start point and the end point is highlighted, and the range of the target character string is indicated, as shown in the display screen of Fig. 6(b). Ru.

Here, when an attribute key such as outline is pressed, the attribute control circuit 51 adds that attribute to each character code of the specified character string, and the text editing circuit 48 stores it as document text in the document text area 43. be done.

Character string range specification is processed by the range specification circuit 57, and attribute addition is processed by the attribute data search circuit 50.

Also, if you press an attribute key without specifying a range, that attribute will be added to the character at the current character cursor position.

Normally, the position of the character cursor C1 indicates the position on the display screen, and is also recognized as the data position in the text area that the cursor is pointing to.

Regarding the movement of the character cursor C1 when specifying a range, the cursor moves so as to follow one character data.

When setting an enlargement attribute, as shown in FIG. 6(b), the starting point is the character or character string to be enlarged.

After specifying the enlargement range by the end point, press the enlargement key 1 day in FIG.

Then, as shown in FIG. 6(c), the character cursor C1 changes to a cursor C2 that indicates the enlarged size on the display screen, and this cursor C2 is moved downward using the up key of the cursor move key group 14. By moving the cursor C2 to the right, you can change the magnification in the vertical direction, and by moving the cursor C2 to the right using the right key, you can change the magnification in the horizontal direction. expressed.

Therefore, the enlargement magnification can be determined by moving the cursor C2 on the display screen.

The cursor C2 is for determining this enlargement magnification.

It does not follow the character data of the text, but moves in consideration of the two physical rows of paper. In other words, Fig. 6 (
c), as shown in (e), aim at the lower right corner of the final character when the character string is expanded, and move the cursor C2.
I'm going to move it.

Then, at the same time as this cursor C2 moves, the enlargement factor determination circuit 53 calculates the available enlargement factor at that time, the enlargement factor display data creation circuit 54 creates display data, and the display screen shown in FIG. 6(c) The vertical and horizontal enlargement magnifications are displayed on the display screen, as indicated by "2X2" in the lower right corner of the screen.

Then, when the execution key 12 is pressed, the enlargement magnification specified at that time is added as an attribute to each character code of the specified character string, and the result is stored in the document text area 43. Then, the attribute data creation circuit 46 and the text display data creation circuit 4 expand the font based on the stored text data, and the state of the enlarged text is displayed on the display screen as shown in FIG. 6(d). to be displayed.

The state of the text when the expanded attribute is added is shown in Figure 5 (b).
). This attribute code is added before all character codes. In this example, an enlargement attribute code is added to the characters (A) and (B), and the enlargement attribute code is as shown in (c) of the same figure. It consists of 2 bytes (byte).

When creating text display data, if a character has some attribute attached to it, the attribute data creation circuit 4 of FIG. 1 performs attribute processing on the font of the character. In the case of the enlarged attribute, the enlarged data creation circuit 47 enlarges and develops the font.

By the way, from the state of the display r@ plane shown in FIG. 8(c),
If you move the cursor C2 to the right in an attempt to further increase the horizontal magnification, it may become impossible to display the frame F by simply extending it horizontally. This is because when a specified character string is expanded horizontally, some of the characters within it may cross the end of the line and slip into the next line.

In such a case, the screen will be displayed as shown in FIG. 6(e). This is because when you move the cursor to the right to triple the width from the state shown in Figure 6(c) (2x height x 2x width), the enlarged character shifts to the next line, as shown in Figure 6. (e)
It will be displayed like this.

Note that moving the cursor C2 in the vertical direction "↑" and "↓" changes the vertical magnification, and moving the cursor C2 in the horizontal direction "←" and "→" changes the horizontal magnification.

Next, attributes will be explained with reference to FIG.

Multiple attributes can be attached to one character. The state of the text at that time is shown in FIG. 7(a).

The attribute code is added before the character code, and there is a 1-byte (byte) attribute instruction indicating what kind of attribute is attached to the character, and then a code indicating the specific attribute is added. It is continuing. One attribute is specified using one byte (byte).

(b) for the character code of (a) shown in Figure 7(a)
When enlarged, outlined, and shaded attributes are added using the attribute code, the attribute code is as shown in the same figure (b), and the specific content follows the first attribute instruction code. Vertical and horizontal magnification, white outline and shading are each 1 by!・It is indicated by the code.

The contents of each of these codes are indicated by the bits "ON/○FFr]-, O" as shown in FIG. Since it is specified in bits, attributes such as outline and bold can coexist.

The order of the attribute contents is determined, and when attributes are added or deleted, they are arranged in that order.

The character code is represented by one word, and the first bit is always in the ON rlJ state. The first bit of the attribute instruction code and the attribute content code are always in the OFF rOJ state.

Therefore, when displaying text, the distinction between character code and attribute code can be determined by the first bit.

Furthermore, if a new setting is made to change the magnification factor for a character that already has the magnification attribute, the magnification magnification portion of the attribute for that character in the text is replaced with the new magnification factor.

Also, if you want to cancel the enlargement attribute, change the enlargement factor to 1x1 and confirm, the enlargement factor part of the attribute code will be deleted and the enlargement instruction bit in the attribute instruction section will be turned OFF. become. All bits of the attribute indicator are O
When the state becomes FF, the attribute instruction section is also deleted.

Also, when a character is deleted, its character code is deleted. If the character has attributes.

Attribute codes added to text character codes are also deleted at the same time.

In this way, when enlarging a part of the input character string using this character processing device, you can arbitrarily specify the character or character string to be enlarged, and then enlarge the character or character string on the display screen. You can specify the size and position of the character by moving the cursor, check its arrangement and magnification, and then enlarge the character. Therefore, the desired character string can be obtained.

Further, it is possible to enlarge characters while maintaining balance with the paper, and there is no need to specify the enlargement magnification in advance.

Furthermore, since the expanded attribute is attached to the character code in the text, processing associated with changes, deletions, and additions is easy.

In other words, file management is easy.

Effects As explained above, according to the present invention, in a character processing device such as a word processor, a part of an input character string can be arbitrarily designated, and the enlarged size of the character or character string can be displayed on the display screen. By checking the size and position of the characters, you can decide on the desired magnification and enlarge the characters as desired.
