Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device (hereinafter referred to as a character processing device) having a document creation and editing function, such as a word processor, an office computer, a personal computer, a data processor, and a workstation. , especially related to character modification processing.

[Conventional technology]

In word processors etc. as character processing devices,
Various types of character (column) modification functions are now available, including white characters, italic characters, underlining, and shading. Therefore, it is often desirable to add these modifications to one character or character string at the same time. For example, italicized text may be underlined.

[Problem to be solved by the invention]

In such cases, conventional devices modify target characters or character strings by overlapping them. That is, the operation had to be performed the number of times corresponding to the type of modification. Therefore, there is a problem in that the more types of modifications that are added at the same time, the more time and effort is required.

Also, when considering the case of removing added modifications, the number of types of keys is limited and the types of modifications are increasing, so in the past, for ease of operation, canceling modifications was not assigned to the same key. There are many cases. That is, if you want to cancel an underline, add the underline to the character again and cancel it.

Therefore, to undo some modified character, use
Since it is necessary to perform operations equal to the number of types of decorations added to the character, canceling multiple types of decorations takes time and the operations are complicated.

Next, thinking about processing speed, each time a modification process is performed, the result is displayed on the display device.
In cases where multiple types of decorations are added to one character, it is very wasteful to perform display processing and text processing each time, and the processing speed becomes slow.

Therefore, conventional character processing devices have problems in that the operability of character modification is poor and the processing speed is also slow.

This invention has been made in view of the above points, and it is an object of the present invention to improve the operability of character modification by enabling a character processing device such as a word processor to process multiple types of character modification at the same time. The purpose is to speed up the processing speed.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a character modification means for modifying input characters or character strings, and a combination modification for modifying and setting by combining multiple types of modifications in the character processing device as described above. The apparatus includes a setting means and a plurality of types of modification means for simultaneously performing a plurality of types of modification combined by the combination modification setting means.

[For production]

When performing multiple types of modification processing on characters or character strings input using this character processing device, multiple types of attribute codes requested for modification by the input device are created by the character modification means, and the created multiple types The attribute codes are combined and set by the combination modification setting means.

Then, the plurality of types of attribute codes set in combination by the plurality of types of modification means simultaneously modify the characters or character strings.

FIG. 1 is a block diagram showing the functions of the control unit 20 related to the simultaneous processing of multiple types of character modification according to the first embodiment of the present invention.

The part related to the simultaneous processing of multiple types of modifications is performed by the input device 4.
1. Input control section 42. Cursor control section 43, menu display control section 44. Text extraction section 45. Modification control section 4th 9 combination modification information storage section 47. Text buffer section 48. Text update control unit 49. CG extraction part 5Q, CG
Font section 51, text display control section 52. It is composed of a modification dot development section 532, a combination modification information creation control section 541, a display control section 55, and a display device 56.

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

The input device 41 is the keyboard 1 shown in FIGS. 2 and 3.
In addition to inputting characters, lines, etc., there is a combination modifier key (when pressed at the same time as the function instruction key 11, it becomes a combination modifier setting key) 16 necessary for simultaneous processing of multiple types of modifications as shown in FIG. It is equipped with

The input control unit 42 determines the next process to be performed based on the data from the input device 41, and transmits the data and instructions to the corresponding circuit.

The cursor control section 43 controls the position of the cursor based on cursor movement data from the input control section 42 .

The menu display control section 44 controls the display of combination modification setting menus as shown in FIGS. 4 and 5 based on instructions from the input control section 42.

The text extraction section 45 extracts the text data at the cursor position from the text buffer section 4 and outputs it to the decoration control section 46.

The modification control section 46 receives a modification request from the input control section 42, retrieves combination information for modifying the text information of the text extraction section 45 from the combination modification information storage section 47, and creates a modification attribute code.

The combination modification information storage section 47 stores the combination modification information created by the combination modification information creation control section 54.

The text buffer section 48 temporarily stores the text created in the configuration shown in FIG. 7(c).

The text update control unit 4 receives a text update request from the decoration control unit 46 and updates the text content of the text buffer unit 48 .

The CG extraction section 50 extracts CG font data from the CG font section 51 in response to a font extraction request from the decoration control section 46 and outputs it to the decoration dot expansion section 53 .

The CG font section 51 includes a character generator, etc.
Holds character pattern data.

The text display control section 52 outputs the text in the text buffer section 48 to the display control section 55 for display.

The decoration dot development section 53 inputs the corresponding CG font from the CG extraction section 50 in response to the modification request from the decoration control section 46, develops it into dots, and outputs it to the display control section 55.

The combination modification information creation control section 54 creates combination modification information based on input data from the menu display control section 44 .

The display control unit 55 performs control for displaying on the display device 56.

The display device 56 is a device such as a CRT or LCD that visually displays characters and lines.
A liquid crystal display device (LCD) 2 shown in the figure is used.

Next, the functions related to simultaneous processing of a plurality of types of decorations on characters according to this embodiment will be explained by dividing them into the following three functions.

- Modification operation - Combination modification setting - Combination modification - Modification operation First, an example of the modification operation will be explained with reference to FIG. 7 and other drawings.

It is assumed that the memory is a 16-bit memory, and the types of character attributes shown in FIG. 7(a) are prepared as character decorations.

Namely, white, shaded, double italic, bold, double-width typeface, half-width, upper ruby, lower ruby, with or without enlargement, and 1. Underline 2. Shading 1. It is shaded 2. When the most significant bit b15 is ON ('1°), the code is regarded as an attribute.

When there is a request for character modification from the input device 41 (in this example, it is assumed that a key labeled "outlined" is pressed), the input control unit 42 determines that this request is a modification request. It is determined and sent to the modification control section on the 4th.

The modification control unit 46 extracts the character at the current cursor position.
This is sent as a character code from the text extraction section 45. A font image corresponding to this character code is extracted from the CG font unit 51 via the CG extraction unit 50. This is for display purposes. The modification control section 46 also generates an attribute code corresponding to a modification request from the input control section 42 .

Currently, the format of the attribute code is shown in Figure 7 (
We will adopt the format shown in a). The reason for formatting in bits is to increase the capacity of the text buffer.

In this case, since we requested outline decoration, b.

The attribute code is obtained by setting b15 to 1°.

This format is when there is no extended attribute.

Therefore, the attribute codes for vertical expansion and horizontal expansion in the text buffer shown in FIG. 7(Q) are not attached.

This generated attribute code is sent from the decoration control section 46 to the decoration dot expansion section 53, where it is subjected to dot processing.

The modification dot development section 53 refers to the bits of the attribute code generated by the modification control section 4, and performs dot processing corresponding to each bit. In this case, outline processing is performed.

In this method, the CG font has only the original normal characters, and all decorations are done by a program. The white font created in this way is sent to the display control section 55 and displayed as an image on the display device 5th.

The decoration control section 4 also updates the text buffer section 48. Specifically, as shown in FIG.
The attribute code generated in step 2 is inserted into the text buffer section 48 and updated. Naturally, if you insert it, the lower character codes will be shifted downward.

When displaying text, always determine which code is one character. This is shown in Figure 7(a,)(b)
The most significant bit b15 shown in FIG.

It is assumed that the most significant bit bls of the character code is not equal to 1°. In this way, text processing, dot expansion and display processing are performed.

Finish a series of modification operations. In other words, this series of modification operations is character modification means.

■Combination modification setting Next, combination modification setting will be explained with reference to the flowchart shown in FIG.

As shown in FIG. 7(a), the combination modification setting is
This is a case where multiple attribute bits become 1 at the same time. In this example, a plurality of types of modifications are performed, such as "enlargement of white outline by 10 degrees" (bo and bto are 1°).

In such a case, conventionally, as described above, normal whiteout processing is performed, attribute code creation and text display processing are performed, and then the same process as attribute code creation is performed in the first enlargement/modification request.

However, in this embodiment, such text display processing is performed twice at once, and attribute codes corresponding to a plurality of types of decorations are generated in advance for this purpose.

First, when a combination modification setting request occurs on the input device 41 (the function instruction key 11 and the combination modification key 16 in FIG. 6 are pressed at the same time), the input control unit 42 determines that it is a combination modification setting request, and the menu A menu display request is made to the display control unit 44.

This menu is as shown in FIG. 4, for example. And the item selected by the number keys is displayed in reverse.

For convenience of illustration, the inverted display is shown with diagonal lines.

The menu display control unit 44 takes in selection information using the cursor movement key group 14 and numerical keys (numeric keys, etc.),
This is sent to the combination modification information creation control section 54, which determines inappropriate combinations and generates attribute codes.

In the attribute code, the corresponding bit is set to 1° as shown in FIGS. 7(a) and 7(b). This is stored in the combination modification information storage section 47 and backed up. This completes the settings.

The combination modification setting menu display shown in Figure 5 is as follows:
In the combination modification setting menu display in Figure 4, the number key is 3.
(Italics removed) → 1 (outline setting) → 8 (half-width setting) is pressed, and then the execution key is pressed.

However, since double-width and half-width modifications are prohibited, a warning message will be displayed saying ``Inappropriate combination, select another degree''.

This combination decoration setting is a combination decoration setting means that sets decoration by combining a plurality of types of decorations.

①Combination Modification Finally, combination modification will be explained with reference to the flowchart of FIG. 11.

Character modification is performed based on the attribute code created by the combination modification setting in (2). This is almost the same as the modification operation in (2). The only difference is that the attribute code has already been created.

When there is a combination modification request on the input device 41 (the combination modification key 16 in FIG. 6 is pressed alone), the input control device 42 sends it to the modification control section 46.

If the modification control unit 4 recognizes that it is a combination modification, it generates the attribute code created with the combination modification setting from the combination modification information storage unit 47 without generating an attribute code based on the type of modification. Take it out.

Then, this is sent to the modified dot development section 53 for dot development. Furthermore, as shown in FIG. 9, the text update control unit 4 inserts the retrieved attribute code into the character code (character code 2) at the current cursor position and updates the text buffer.

The subsequent steps are similar to the modification operation in (2).

That is, a combination of a plurality of types of decorations set by the combination modification setting in (2) is processed simultaneously by the combination processing (2). This is a multi-type modification means.

In this manner, when a plurality of types of modification processing are performed on one character using this character processing device, the time required for this can be shortened, and the key operations and the like required for this can be simplified.

Furthermore, it is possible to cope with an increase in the number of character modification types.

Furthermore, since frequently used modifications can be arbitrarily registered, document editing efficiency can be improved.

Next, a second embodiment of the present invention will be described, but since its appearance and the hardware configuration of the control section are the same as those shown in FIGS. 2 and 3, the description will be omitted. Omitted.

FIG. 12 is a block diagram showing functions related to user character modification processing according to the second embodiment.

That is, the same input device 41 as in the first embodiment. In addition to the input control section 422, the display control section 55, and the display device 56, the print control section 57. Printing device 582 Document editing control section 592 Character modification control section 602 Document text storage section 619 Character modification method storage section 621 Character pattern processing section 639 Character pattern generation section 64. This function is performed by the external storage control section 65 and the external storage device 66.

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

Note that explanations of parts having the same names as those in the block diagram of the first embodiment will be omitted.

The printing device 58 is the thermal printer 3 in the example shown in FIGS. 2 and 3, and the print control section 57 is a printer control function performed by the control section 20.

The document editing control section 59 inputs character data input from the input device 41 and discriminated by the input control section 42, edits the data, and sends the character data to the character modification control section 60 and the document text storage section 6.
1 or output to the display control section 55.

When the character modification control section 60 receives a modification request from the document editing control section 5, it displays an editing screen as shown in FIG. The processing section 63 is activated to create a user character modification method, and when it is displayed and determined, it is stored in the character modification storage section 62.

The document text storage section 61 stores text data such as character data and attribute data from the document editing control section 5 and the character modification control section 60. Then, if necessary, this is stored in the external storage device 66 via the external storage control section 65.

The character modification storage section 62 stores the user character modification method created and determined by the character modification control section 60, and stores this in the external storage device 66 via the external storage control section 65.

The character pattern processing section 63 processes character patterns through routines as shown in FIG. 15(b).

The character pattern generator 64 is a character generator that stores character patterns of predetermined fonts such as Gothic and Mincho fonts in the dictionary memory 24 described in FIG. 3.

External storage control unit 65 and external storage device 6th.

In the example explained in FIGS. 2 and 3, there are a floppy disk controller (FDC) 27 and an FDD 4.

Next, the operation of this second embodiment configured in this way is as follows.
The following three functions will be explained.

■ User modification registration ■ User modification setting ■ Modification registration/calling ■ User modification registration User modification registration is a function in which the user (user) sets a character modification method and registers it in the internal storage section of the device.

When a request for user modification registration is input from the input device 41, the input control section 42 determines it, and control is transferred from the document editing control section 59 to the character modification control section 60.

In the character modification control section 60, for example, as shown in FIG. 13, "User character modification" is displayed in the current/state transition display section a at the top of the screen, and "User character modification" is displayed in the function selection display section Fl at the bottom of the screen. Edit screen C is displayed with "Modification" and "Registration" displayed on F2.

Note that Fl stands for function key 1 and F2 stands for function key 2. The function keys are each key of the function key group 15 in the keyboard 1 shown in FIG. 2, and in this example, five function keys F1 to F5 are provided.

Therefore, when the function key F2 is pressed to perform user modification registration, an editing screen C as shown in FIG. 14 is output.

That is, "User character modification: registration" is displayed in the current state transition display section a, the current registration state is displayed in F1 to F3 in the lower function selection display section, and the current registration state is displayed in F4.
Nothing is displayed on F5, indicating that it is currently unregistered.

On this screen, a total of five types of registration from F1 to F5 are possible. Now, if the function key F4 is selected to perform new registration, a screen as shown in FIG. 15(a) will appear.

FIG. 15(b) shows that the numeric keys 0 to 6 and the cursor movement keys in FIG. 15(a) are individually associated with each routine of the character pattern processing section 63.

For example, when the cursor right movement key "→" is pressed, a processing section that executes a font overlapping movement routine in the character pattern processing section 63 is activated.

As a result, the rA4 shown in FIG. 15(a)
becomes thicker on the right side.

"rA" on the screen is provided only to clarify the current modification registration status, and means that all characters are modified in the same way as rAJ is modified.

Therefore, any character other than "A" may be used.

Also, if you use the numeric keys 0 to 6 in Fig. 15(a) in combination with the cursor movement keys, you can use the cursor movement keys in Fig. 16(a) to
) is possible.

For example, as shown in Figure 17, the number key "5" makes "A" thicker horizontally, the number key "6" makes it thicker vertically, and the cursor movement keys "↑" and "←" add a shadow to the upper left. repeated twice and the number key "2" which hollows out the original font "A"
When the operations using each key are executed sequentially, the first
As shown in FIG. 6(a), a character rA4 with a shadow (less shape) in the upper left is realized.

These combined input key code groups are temporarily stored each time the user inputs them.

At this time, the key code may be stored as is, but for ease of explanation here, a numerical value will be assigned to each input key and the numerical value will be temporarily stored. A corresponding diagram is shown in FIG.

Numeric key rlJ ~ "6" is stored as the numerical value, and rQJ is stored as the numerical value "7". Furthermore, among the cursor movement keys 14 that instruct "superposition movement", the cursor up movement key "↑" has a numerical value of 100° and the cursor up movement key "↓"
is the numerical value 1o1. The cursor right movement key "→" has a value of 102
．． The cursor left movement key "←" is stored as a numerical value 103.

In addition, in the case of a combination operation of the function instruction key 11 marked with ★ to instruct "simple movement" and each key of the cursor movement key group 14, the cursor up movement key ``↑J is a numerical value 2
0o, cursor up movement key "↓" is 201. The cursor right movement key “→” is stored as 202, and the cursor left movement key “←” is stored as 203.

Once the promise is made in this way, in the operation shown in FIG. 17, the modification is saved as shown in the user 1 modification storage area shown in FIG. 19. Here, it is assumed that the numerical value "-1" indicates the end of stored information.

The order in which the user inputs values is important because the modification result will be different depending on the order in which the numerical values are input.

In this way, when the execution key 12 is finally pressed,
The content that has been temporarily stored in the title is officially registered in the character modification control section 62.

This officially registered information is used for modification settings and registration/calling, which will be described later.

The flowchart shown in FIG. 20 is for performing the user modification registration process up to this point, and the flowchart shown in FIG. 21 is for performing the processing for developing character patterns in user character modification.

A detailed explanation of these flowcharts will be omitted as it is believed that they will be fully understood from the above explanation.
``Initialize internal work'' in Figure 0 represents writing ``-1'' to the beginning of the storage area, and ``r character pattern development'' is the content expressed in the flowchart shown in Figure 21. "Display" means the pattern is displayed on the display device 5
6. In this way, user qualification registration is completed.

■User modification setting The user modification setting is a function to actually modify characters using the character modification method registered in the user modification registration in (■).

If the information that a character is modified is not stored somewhere, the character pattern processing unit 63 in FIG. 12 cannot be activated, so a "character attribute code" is used.

This is a code that indicates what kind of character modification is set for that character, and has a structure as shown in FIG. 22(a), for example.

This attribute code is added immediately before the modified character code in the document text storage section 61 in which the currently inputted document text is stored.

This attribute code is added to each character.

As shown in FIGS. 22(a) and 22(b), character codes and attribute codes can be determined by whether the most significant bit bis is 1° or 0°. That is, if the bit bls is 1° as shown in (a), it is a character attribute code, and if the bit bls is 0° as shown in (b), it is a character code.

Using this format, display control section 55 and print control section 57 read one character from document text storage section 61 through character modification control section 60 and output to display device 56 and printing device 58, respectively. This is the same between general character decorations such as outlines and shading, and other user character decorations.

When a user character modification request occurs on the input device 41, the input control unit 42→document editing control unit 59→character modification control unit 6
Control transfers to 0.

The character modification control section 60 outputs the editing screen shown in FIG. 13. If the function key F1 is pressed here, the editing screen shown in FIG. 14 is output, and it is possible to select which user modification is to be made.

When you select any of the function keys F1 to F5, the current button at the top of the screen appears, for example, as shown in Figure 23(a).
"User character modification: Modification" is displayed in the state transition display section a, and the edit screen C appears, with "Please specify the setting range" displayed in the function selection display section at the bottom. ``Specify.

Here, as shown in Figure 23(b), if you specify the range of ``reokaki'', the display of the character strings in the specified range will be reversed (
(indicated by diagonal lines).

Thereafter, when a setting is input using the function key F1, the one-character modification control section 60 adds the above-mentioned attribute code to the specified text in the document text storage section 61.

Here, function keys Fl to F shown in FIG.
5, b2 to b6 in FIG. 22(a), that is, user 1
If user 5 is made to correspond, it is possible to determine which user modification is used when reading one character, as shown in FIG. 24.

Next, the process of displaying and printing these user-modified characters will be explained.

As mentioned above, since the attribute code has already been added to the document text storage section 61 in FIG. 12, all that is left is to read it and develop the character pattern.

Here, FIG. 25 shows a flowchart of character pattern development after reading one character.

Whether the read character is modified or not is determined by whether the most significant bit 15 of the code shown in Figure 22 is 1° as described above.
Determine whether it is 0°.

If an attribute code is included, character pattern processing corresponding to each bit of the attribute code is performed.

In the case of outline or shading, character pattern processing is directly performed, but in the case of user modification, registration information is first analyzed, and based on the result, character pattern processing is performed according to the flowchart shown in FIG.

In this way, one character is read and the development of that character pattern is completed. After that, the print control section 57 outputs the developed pattern to the printing device 58, and the display control section 55 outputs the developed pattern to the display device 5B.

Print or display.

■Registering/calling a modification Registering/calling a modification registers the character modification method information set and registered in the user modification registration in ■ from the internal storage to the external storage device, and also registers the information registered in the external storage device. This is a function to call up and delete information on character modification methods.

When a request for registering/calling a modification occurs in the input device 41 shown in FIG.
Control is transferred to

The external storage control unit 65 allows selection of what to handle, for example, as shown in FIG. 26(a).

If modification is selected using the function key F4, a screen of "Registration/Call: Modification" appears as shown in FIG. 2(b), and the user is prompted to select what process to perform displayed at the bottom. When registration of Fl is selected, a screen for inputting a document name and notes as shown in FIG. 6(c) appears, and the document name is input to control the connection with the external storage device.

In other words, for the external storage control unit 65, there is no fundamental difference between the modification information and the document text, and they are treated as mere data. The only difference is where the data is stored.

When registering modification information, the information in the 1-character modification storage section 62 is registered in the external storage device 66, when it is called, it is loaded from the external storage device 6 and transferred to the 1-character modification storage section 62, and when it is deleted, it is loaded from the external storage device 66 and transferred to the 1-character modification storage section 62. Delete the specified file in 6B.

In this way, in the second embodiment, the number of types of character decorations increases, so the degree of freedom is increased, and various miscellaneous character decorations can be grouped together to some extent, making the operation easier.

Furthermore, since the user can freely modify one character, there is no need to worry about the future, and since various character modifications can be supplied from an external storage device, modification information can be received and passed between machines of the same model. Additionally, unlike external characters and images, they require less internal storage capacity.

Therefore, according to the second embodiment, the user can freely create attribute codes for character decorations, and set multiple combinations of the created various character decorations as in the first example, thereby creating multiple types of decorations that simultaneously modify the attributes. If the characters are modified by means, character modification can be performed with a higher degree of freedom.

Next, a third embodiment of the present invention will be described.The appearance and the hardware configuration of the control section are the same as those shown in FIGS. The functional block diagram for implementing the third embodiment is also substantially the same as that of the second embodiment shown in FIG. 12, so illustration and description thereof will be omitted.

The functions of this third embodiment can also be broadly classified into the following three operations, similar to the above-mentioned second embodiment.

■User qualification registration ■User modification settings ■Register/call modification Below, each of these functions is shown in FIG. 12 of the drawings.

This will be explained in sequence with reference to FIG. 17 and FIG. 27 onwards.

■User Modification This is a function in which a registered user (user) sets a character modification method and stores it in the internal storage of the device.

When this user modification registration request is generated in the input device 41 of FIG. 12 by the user's key input, it is determined by the input control section 42, and the character modification control section 608 is controlled from the document editing control section 5. Transition.

At this time, the character decoration control section 60 outputs a screen as shown in FIG. 27, for example, to the display device 56 via the display control section 55. In this screen display, the current state transition is output on the bottom line, and a display for function selection is output on the bottom line.

In this embodiment, it is assumed that the input device 41 (function key group 15 in the keyboard 1 in FIG. 2) is equipped with eight function keys F1 to F8.

Now, when the user presses the function key F2 to register a user modification, the one-character modification method control section 60 outputs the screen shown in FIG. 28 on the display device 56. On this screen, the current qualification registration status is shown in the function area.

According to this Figure 28, there are a total of 8 types of registration possible, F1
~ Something has already been registered in F6.

In this example, there is a system preset modification in Fl-F6, but of course this can also be changed.Here, when a shaded character is selected using the function key F5, the character modification control section 60 2nd on the 5th
The screen shown in Figure 9 will be output and the settings will be waited for.

The upper left part of this screen displays the result of actually modifying and developing character patterns using the currently selected modification registration information.

Assuming that this modification information is stored in the format shown in FIG. 30, the modification information F1 to F8 in FIG. 28 is stored internally as numerical information as shown in FIG. 31. The storage location of this information is fixed, and the information is retrieved from here when any user modification is performed. This will be discussed when explaining user modification settings.

In FIG. 30(a), bit b5. ba is, for example, °00°: none.

°01°: overlapping, °10°: hollowing out.

The figure (b) is information added when any one of b2 to b4 in (a) is 1 degree, and in the vertical direction, the lower value is a positive value and the upper value is a negative value. Also, in the horizontal direction, the right side is a positive value,
Set the left side to a negative value.

When the display screen of FIG. 29 is being output, only the cursor movement keys, numeric keys, execution key, and cancel key are permitted. Whenever any setting is made using these keys, information in the format shown in FIG. 30 is created each time, and this information is used to develop the pattern of the basic font.

This pattern development is performed in the order of reduction → light character. This is the order of the items displayed from top to bottom on both sides of the display in FIG. This order is specific to this system and is set taking into account qualification results.

In this way, the upper left r A J is modified for each setting, and when the execution key is pressed, the settings are stored in the storage section F5 shown in FIG. 31.

Flowcharts of each process of user modification registration and user character pattern expansion described above are shown in FIGS. 32 and 33.

This completes the user qualification registration. As an example of character modification, please refer to the example shown in FIG. 16 when explaining the second embodiment.

This is a function that retrieves the information set and stored in ■User Modification Settings■ and actually performs character modification.

If the information that a character is modified is not stored somewhere, the character pattern processing unit 63 shown in FIG. 12 cannot be activated.

use. This is a code that indicates what kind of character modification is set for that character. For example, in Figure 34 (a
) has the structure shown in

This attribute code is added immediately before the modified character code in the document text storage section 61 in which the currently inputted document text is stored.

This is done for each character.

The attribute code shown in FIG. 34(a) and the character code shown in FIG. 34(b) can be distinguished by whether the most significant bit b15 is 0° or 1°.

Using this format, the print control unit 57 in FIG.
The display control unit 55 reads one character from the document text storage unit 61 through the character modification control unit 60, while
They output to a printing device 58 and a display device 56, respectively. This is the same for general character decorations such as italics and double-width characters and user character decorations.

Now, when a request for user character modification occurs on the input device 41, control is transferred from the input control section 42 to the document editing control section 59 to the character modification control section 60. Then, the character modification control section 60
outputs the display screen diagram shown in FIG. 27 on the display device 56.

Here, when the user presses the function key F1, the display screen shown in FIG. 28 appears, and it is possible to select which user modification to perform.

When any one of the function keys F1 to F8 is selected, the display screen shown in FIG. 35(a) is displayed, and the character to be modified can be specified within a range.

When you specify the start and end of the string you want to modify using the cursor movement key and execution key, the display of the string in the specified modification range is reversed (shown with diagonal lines) as shown in Section 35 @ (b). .

After specifying the modification range in this way, if the function key F1 is pressed to set it, the character modification control section 60 adds the above-mentioned attribute code to the specified text in the document text storage section 61.

Here, the bits bo in FIG. 34 are set to F1 to F8 in FIG. 28.
By making '=b'y correspond, it is possible to determine which user modification is used when reading a single character.

Next, the process of displaying and printing these user-modified characters will be explained.

As mentioned above, since an attribute code has already been added to the document text, the only thing left to do is read it and develop a character pattern. A flowchart of this single character reading process is shown in FIG.

Whether the read character is modified or not is determined by whether the most significant bit b15 is 1° or 0°, as shown in Figure 34.
Determine by If an attribute code is attached, character pattern processing corresponding to each bit of the attribute code is performed.

In the case of italics and double-width, the character pattern is directly processed, but in the case of user modification, the registered information is first analyzed, and the character pattern is processed based on the result.

In this way, one character is read and the character pattern is developed. All that is left to do is print the developed pattern using the print control unit 57! i! to 58, display control unit 55
If so, it is output to the display device 56 and printed or displayed.

■Registering/recalling modifications■Registering the information set and stored in the external storage device (
This function also includes calling from an external storage device and deleting registered information.

When this request is generated by the user's key input on the input device 41 of FIG. 12, control of the external storage control unit 658 is transferred via the input control unit 42.

In the external storage control unit 65, in the same manner as described above with reference to the display screen of FIG. 26 in the second embodiment, first the user selects what to handle (a), and then the user selects what process to perform. (b), the document name is inputted, and (c) registration is controlled with the external storage device 6B.

Retrieving or deleting the modification information registered in the external storage device 66 is also the same as in the second embodiment, so a description thereof will be omitted.

According to this third embodiment, the following effects can be obtained.

(1) Since the number of types of character decoration increases, the degree of freedom in decoration increases.

(2) Various miscellaneous character modifications can be grouped together to some extent, making operations easier.

(3) Character decoration can be freely done by the user, so there is no need to worry about it in the future.

(4) Since various character decorations can be supplied from outside, decoration information can be received and passed between different machines as long as they are the same model.

(5) Unlike external characters and images, internal storage capacity is small.

〔Effect of the invention〕

As explained above, according to the present invention, in a character processing device such as a word processor, when there are multiple types of modifications to a character, these can be modified simultaneously, thereby improving operability and increasing processing speed. be able to.
