Abstract

PURPOSE:To automatically change a character to a designated type style when the character is inputted by providing a character designating means to designate the character, whose type style is changed, before the character is inputted. CONSTITUTION:In the respective types of character processors such as a word processor, etc., the character already inputted is designated and the type style is changed to the other type style by a type style changing means. In addition to this conventional technique, the character, whose type style is changed, is designated by a character designating means in advance. Then, when the character designated by the character designating means is inputted, the type style is automatically changed by an automatic type style changing means and the character is inputted. Accordingly, it is not necessary to execute a type style change after the input and the change of the type style can be prevented from being forgotten. The type style can be returned to the original type style and the indication of the type style change can be also executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to various character processing devices such as word processors.

[Conventional technology]

2. Description of the Related Art Conventionally, in various character processing devices such as word processors, there are devices in which a variety of fonts for characters input through an input device can be prepared and switched. This typeface includes Mincho font, Gothic font, brush font, etc. 1 Normally, Mincho font is the font that is displayed/printed, and by specifying characters and changing the font, Gothic font, brush font, etc. It is possible to change to.

To switch the font, the user specifies the input character and instructs the user to change the font, which is effective only for characters that have already been input. Additionally, some devices have a function to switch the font for the entire document, but this also involves switching the font when printing characters that have already been input.

[Problem to be solved by the invention]

However, when using these functions, for example, if you want to change the font of only a specific type of character such as a number and print it, you must enter the number and then specify the font change to change the font, making it very difficult to operate. It was a hassle.

In addition, when there are many input points for font change, it is necessary to instruct the font change for each input point, making the operation difficult and causing problems such as forgetting instructions to change the font, making incorrect operations, and other problems. there were.

Furthermore, if a character whose font is specified cannot be displayed in the changed font on the display screen, even if the specification is forgotten, it cannot be discovered unless it is printed, which is even more problematic. That is, having to instruct the user to change the font of input characters is convenient because the user can freely change the font later, but at the same time, it makes inputting operations cumbersome.

This invention was made in view of the above points, and leaves the function of instructing the font change of characters that have already been input as is, and automatically changes the font when inputting characters. The purpose is to prevent forgetting to change the font by making it possible to specify the font in advance and specifying the character.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a font changing means for instructing a character already inputted from an input device to change the font to another font in a character processing device as described above, and The device is equipped with a character specifying means for specifying a character whose font is to be changed, and an automatic font changing means for automatically changing and inputting the font when the character specified by the character specifying means is input.

[For production]

In the character processing device according to the present invention, if a character whose font is to be changed is specified by a character specifying means for specifying a character whose font is to be changed before inputting a character, when that character is input by an automatic font changing means, Since the font is automatically changed to the specified font when input, it is possible to prevent forgetting to change the font.

The printer control section 5 includes a print buffer control section 60 and a print buffer 61.

The input device 1 is a keyboard, the display device 2 is a liquid crystal display (LCD), and the printing device 3 is a thermal printer.

The input control section 40 discriminates data input from the input device 1 and transmits the commands to each section. That is, one character data is transmitted to the character editing section 41, a font change instruction is transmitted to the font control section 43, a font setting instruction is transmitted to the font setting control section 45, and a print instruction is transmitted to the print control section 5.

Character editing section 41 outputs character data from input control section 40 to character storage control section 42 and display control section 48 . Also, the font type setting table 47 is selected from the input character data and the setting status of the internal switch 46, and if there is an input character in the table, a font change control code is added and the character storage control unit 42 is activated. It is stored in the continuous character storage area (text buffer) 44.

The character storage control section 42 receives character data from the single character editing section 41 and font control codes for characters whose font has been changed from the font control section 43, and stores them in a character storage area (text buffer) 44.

The font control section 43 outputs the control code to the character storage control section 42 in response to a font change instruction from the input control section 40 .

The character storage area (text buffer) 44 receives character data from the character storage control unit 42, and receives control codes for characters whose font has been changed, and stores them.

When the font setting control unit 45 receives a font setting instruction from the input control unit 40, the font setting control unit 45 displays a font selection screen as shown in FIG. 9 to control the font setting, and changes the font for any type of character. Let them choose.

The internal switch 46 sets the switch for the character type selected by the font setting control section 45.

The font type setting table 47 stores a character table as shown in FIG. 13 corresponding to the selection screen shown in FIG. 9.

The display control unit 48 sends character data to be displayed to the character editing unit 4.

The character font extraction unit 4 receives the character data to be displayed from the display control unit 48, instructs the gate 50 using the character code, and extracts the extended font C from the Mincho typeface CG51.
The font data is accessed by switching to G (Gothic) 52 (or vice versa), and the font data is taken out and set in the display memory 53.

The gate 50 selects Mincho typeface CG51 or extended font CG (
Gothic font) 52, extracts the font data, and outputs it to the character font extractor 49.

Mincho font C (351 is a character generator that stores character patterns of Mincho font characters.

The extended font CG (Gothic) 52 is a character generator that stores character patterns of Gothic characters.

The display memory 53 temporarily stores font data to be displayed from the character font retrieval unit 49, and displays the font data on the display device 2.
Output and display.

The gate 54 switches to the Mincho font CG 51 or the extended font CG (Gothic) 52 according to the character code from the print font extractor 58, extracts the font data, and outputs it to the print font extractor 58.

When the font is switched during printing, the font switching control unit 55 causes the gate 54 to extract the font data of the font, and causes the print font extraction unit 58 to output it.

When the print control section 56 receives a print instruction from the input control section 40, it transmits the instruction to the text information extraction section 57 and the printer control section 5.

The text information retrieval unit 57 retrieves the corresponding character data from the character storage area (text buffer) 44 according to instructions from the print control unit 5, and sends it to the print font retrieval unit 5.
Output to 8.

The print font extractor 58 instructs the gate 54 or the font switching controller 55 to receive the corresponding font data based on the character data from the text information extractor 57, and outputs it to the print buffer controller 60.

The printer control section 59 controls the printing device 3 according to instructions from the print control section 56 and operates it.

The print buffer control section 60 receives font data of characters to be printed from the print font extraction section 58 and outputs it to the print buffer 61 .

The print buffer 61 receives font data of characters to be printed, stores the font data, and sequentially outputs it to the printing device 3.

Next, the functions of this embodiment configured as described above will be specifically explained with reference to FIG. 4 and subsequent sections.

For example, when "23rd" is input in Mincho font as shown in FIG. 4(a), the text buffer 44
It is as shown in Figure (b). At this time, the cursor is at position 2 in Figure 5(a), and when a font change instruction is given here, the font of °2° is changed to Gothic as shown in Figure 5(a), and the cursor is becomes the position of the next character r3J.

At this time, a control code in Gothic font is added to the text buffer 44 before "2" as shown in FIG. 5(b).

Now, if you give the instruction to change the font again, as shown in Figure 6(a).
As shown in , the font of °3° is changed to Gothic. At this time, in the text buffer 44, as shown in FIG. 6(b), a control code in Gothic font is added before "3". In this example, the Gothic font was used as the font for the font change.

In this way, the control code for changing the font is inserted just before the character code, making it possible to change the font on a character-by-character basis.

In the block diagram shown in FIG. 1, this font change instruction is transmitted from the input control section 40 to the font control section 43, and the font control section 43 searches for the character to be changed through the character storage control section 42. , add a control code.

If the control code has already been added, delete the control code and undo the font change. Displaying character data to which a control code has been added is instructed from the character font extraction unit 49 to the gate 50 when the character code from the text buffer 44 is extracted.

The gate is switched and an instruction is given to access the extended font CG52 from the Mincho font CG51.

This makes it possible to extract and display font data including changes in typeface. When printing, the font is similarly changed, set in the print buffer 61, and printed. The print buffer 61 at this time becomes as shown in FIG.

In FIG. 7, when the changed font is not displayed, it is displayed in reverse as shown in the figure to distinguish it from the part where the font has not been changed.

Next, the font setting instruction according to this embodiment is transmitted from the input control unit 40 to the font setting control unit 45, which displays a selection screen as shown in FIG. By inputting , the switch of the selected character type is set in the internal switch 46.

When character types are set, normal character input becomes possible, but when characters are input at this time, the font type setting table 47 is selected in the character editing section 41 based on the setting status of the internal switch 46, If there is a character input in the table, a font change control code is added and the character is stored through the character storage control unit 42.

Since the control code is added, the display control unit 48 and print control unit S6 change the font and display/print.

On the screen shown in Figure 9, the "number" of the selected number 1
is displayed in reverse video. You can set as many numbers as you like, and as many numbers as you like will be highlighted.

If you select an item that is already highlighted, the highlighting will be canceled and no settings will be made.

When switching the font is instructed during printing, a command is transmitted from the print font extraction section 5 to the font switching control section 55 .

As shown in Figure 10, the "th" and "rth" without control code
has a control code attached to it, and
2" and "3" are controlled so that the gate 54 is switched without a control code.

Therefore, when no font is being changed, the opposite operation is performed.

FIG. 11 shows an internal code and a display example when the 23rd "23" shown in FIG. 6 is canceled by changing the font. That is, as shown in FIG. 11(a), "2"
and "3" are given control codes in Gothic fonts, and "23" is displayed in Gothic fonts as shown on the right side of the figure.

Here, as shown in Figure 11(b), when the Gothic font of "2" is canceled, the control code before "r2" disappears and returns to the Mincho font, and only "3" is in Gothic font, as shown on the right of the figure. becomes.

Furthermore, as shown in Figure 11 (C), when the Gothic font of "3" is canceled, the control code before "3" also disappears, and there is no control code, and as shown on the right of the figure, "23rd " is displayed.

Next, a change in the font of a specific character such as ``invention'' will be explained with reference to FIG. 12.

Figure 12(a) shows Figure 9 in more detail.
Next to "Kanji", there are idioms 1 to 7 to 9. Idiom 2. It is assumed that up to 3 idioms can be set. 1-6 are fixed items, 7-9
is a variable item.

Here, in order to change the font of the kanji ``invention'', if you select ``Kanji'' in fixed item 6 in Figure 12 (a), a screen as shown in Figure 12 (b) will be displayed, and the font for Idiom 1 will be displayed. An input waiting screen will appear.

Here, if you input "Hatsumei" and press the conversion key as shown in Figure 12(c), it will be converted to kanji and displayed as "Invention" as shown in Figure 12(d). . here,
When the execution key is input, the variable item area 7 and idiom 1 of the table (invention) are entered as shown in Figure 12(e).
is set. As a result, for example, as shown in FIG. 12(f), only the font of the characters "invention" in the character data string "inventor is" is changed.

This is shown in internal code as shown in FIG. First, when selecting numbers from fixed tables N001 to N006, since the character codes are continuous internal codes, they have a start internal code and an end internal code.

When start internal code ≦ character code ≦ end internal code,
A control code is added if a match is found, and no control code is added if the conditions are not met.

As shown in the figure, in the case of numbers, the starting internal code is °1.
In the case of an alphabetic character, the end internal code is °0°, and the start internal code is °A° and the end internal code is Z°.

Further, 7 in the variable table shown in FIG. 13 is "invention" and the number of characters is set to "2".

In addition, when changing fonts other than Gothic, such as Brush font and Ryokan font, the extended font C of that font can be changed in the same way as above.
You can change the font by adding G.

Next, the operation of the embodiment will be explained with reference to flowcharts shown in FIGS. 14 to 16.

FIG. 14 is a flowchart of a font setting instruction that functions as a character specifying means for specifying a character whose font is to be changed in advance.

First, the font setting instruction screen shown in FIG. 9 is displayed.

Next, the numbers 1 to 6 are input, and it is determined whether or not the input of the numbers has been completed. If the input of the numbers has not been completed, the characters corresponding to the input number are displayed in reverse video, and this loop is repeated until the input is completed. When finished, set the inverted part to the internal switch and finish.

15 and 16 function as an automatic font changing means that automatically changes the font and inputs the character when the character specified by the character specifying means is input, FIG. 15 is a flowchart of character input.

Input characters from the input device, store them in the character storage area, and perform pointer calculations. Next, it is determined whether or not the input character has a font setting instruction, and if so, a font control code is generated and inserted into the text area. Then, the character code is inserted (even if there is no font setting instruction), the first cursor position is calculated, this is displayed, and the process ends.

FIG. 16 is a flowchart for display. First, a character code is extracted from the text buffer, and a CG address is calculated from the character code. Then, it is determined whether or not to change the font, and if the font is to be changed, data is extracted from the font switching font CG.

If the font is not changed, data is extracted from the standard font CG. Then, this data is set in the display memory and this loop is repeated until the data to be displayed on the screen is completed.

Note that when printing, the character code is extracted from the text buffer, the same processing is performed, and the data is set in the print buffer and printed.

In this way, in order to cover the shortcomings of the conventional technology, the technology that instructs the font change for characters that have already been input remains as is, and the font is automatically changed when inputting and the characters to be input are specified in advance. If the font is specified by the character specifying means and the character is specified by the character specifying means, the font is automatically changed by the automatic font changing means, so it is possible to prevent forgetting to change the font.

[Effects of the Invention] As explained above, according to the present invention, by selecting in advance to input numbers etc. by changing the font, the font can be automatically changed without changing the font after inputting the numbers. If the font has been changed and you want to return to the original font, you can return to the original font by instructing the font to change according to the character, making it very easy to use and less likely to make mistakes when inputting characters. becomes possible.
