Description

TECHNICAL FIELD The present invention relates to a character string processing device, for example, a word processor, a typewriter with memory, an office computer, and the like, and to a character string processing device for outputting a part of an input character string in different fonts.

2. Description of the Related Art For example, in a Japanese word processor or the like, the font of the characters to be output is fixedly determined by the character generator font.
Many Gothic fonts are used.

In recent years, a device for switching and outputting these Mincho and Gothic fonts has been developed, and it is possible to mix Mincho and Gothic fonts in a sentence. When displaying such a font switching specification on a display screen such as a CRT, a control code for font switching is used, and the control code is inserted into the text composed of the characters to be displayed. The font of the characters after the code is switched and output when printing.

In such a system, since the control code is inserted on the display screen and the control code itself is not printed, the printed document and the characters displayed on the display screen have different images. Therefore, it is difficult to create a document on the display screen because the image of the printed document does not appear even when the display screen is viewed. In addition, since it is necessary to search for a control code of one character to make a judgment when visually recognizing from where to where the characters displayed on the display screen have different fonts, there is a drawback that it takes time to judge the font. is there. Particularly in the case of a display device having a small screen, scrolling or the like is performed for searching, so that it is difficult to understand the range of characters having different fonts, and there is a drawback that it takes time to create and edit a document.

In order to eliminate such a defect, it is conceivable to actually switch the font of characters on the display screen and display the characters as they are printed on the display screen. However, in order to display different character fonts on the display screen in this way, a font switching circuit is required.
The disadvantage is that the device is expensive. Further, when a plurality of types of fonts can be switched, it is necessary to make a selection each time each of them is switched, and there is a drawback that the operability is low and it is difficult to use.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, to provide a character string processing device which has good operability and can easily visually recognize characters of different fonts on a display screen.

Structure In order to achieve the above object, the present invention edits character string data and input means for inputting an attribute instruction indicating that an attribute should be added to a character included in the character string data, and the input character string data. An edit processing unit for processing, a display unit connected to the edit processing unit for displaying character string data and an attribute of a character included in the character string data, and a display unit connected to the edit processing unit for converting the character string data into plural types of attributes. In a character string processing device having a printing means capable of printing out, the printing means has a font designating means for designating a type of font of a character to be printed, receives the character string data from the editing processing means, and receives the character string data. When the attribute designation is included in the character string, the character string data is printed out in the character style designated by the character style designating means.
Hereinafter, a specific description will be given based on an embodiment of the present invention.

FIG. 1 shows an embodiment of a character string processing device according to the present invention.

As shown in FIG. 2, the present apparatus includes a keyboard 202 having character keys such as kana, alphabets, numbers, etc., and function keys such as a conversion key, a cursor movement key, a font switching key, an execution key, and a font switching switch. It has an input device 2 including 204, the output of which is connected to the input controller 4. The conversion key is a control key for instructing execution of kana-kanji conversion in the Japanese word processor function in this embodiment. The cursor change key
A key for instructing the movement of the cursor displayed on the display screen of the display device.

In this embodiment, the font switching key is a key for instructing to switch the font between Mincho typeface and another typeface, for example. Other fonts that can be switched by the font switching key include Gothic font, bold Gothic font, italic font, white font, etc. In the present embodiment, conversion between Mincho font and Gothic font will be described. Further, the font changeover switch 204, in the present embodiment, instructs to change the font of the characters to be printed to the Gothic font only with the control code.

The input control unit 4 identifies the key input data input from the input device 2, distributes the character string data by the character keys and the control instruction by the function keys, and according to them, the character edit control unit 8 and the control code control unit 6 , The switching control unit 12 and the like to give an instruction to each functional unit and to send data to them.

When the input by the font switching key of the input device 2 is input through the input control unit 4, the control code control unit 6
The character edit control unit 8 is controlled to determine whether or not the character at the current cursor position stored in the character storage area 10 already has a control code. The control code of the corresponding character stored in the character storage area 10 is deleted, and if there is no control code for the character at the current cursor position, the control code is inserted.

The character edit control unit 8 is a functional unit having a normal Japanese word processing function in this embodiment. This includes, for example, various kana-kanji conversion for each phrase, roman kana-kanji conversion, various editing processes such as insertion, deletion, and movement of character string data, and a conversion dictionary for them.

The character storage area 10 is connected to the character edit control unit 8,
The character data and the control code input from the input device 2 through the control code control unit 6 are temporarily stored.

In response to a display request from the control code control unit 6, the character display control unit 14 reads the character code and control code stored in the character storage area 10 and evaluates each code one by one. If the code is a character code, CG font for display as it is
The corresponding font data is read from 16 and transferred to the display data storage unit 20.

Mincho font data is stored in the display CG font 16.

When the code is a character code with a control code, the character display control unit 14 outputs the character font read from the display CG font 16 to the attribute control unit 18. Attribute control unit 18
Outputs the lower half of the character font sent from the character display control unit 14 to the character display control unit 14 after black and white inversion processing.

The character display control unit 14 also transfers the lower half sent from the attribute control unit 18 to the display data storage unit 20 as a character font whose black and white is inverted.

Further, the character display control unit 14 outputs an output command to the display control unit 22. In response to an output command from the character display control unit 14, the display control unit 22 reads the character font stored in the display data storage unit 20 and the character font in which the lower half is subjected to black and white inversion processing, and sends it to the display device 24. The display device 24 displays these characters as shown in FIG. 3 (a). That is, the characters that should be displayed in Mincho font are displayed normally, and the characters displayed in Gothic font are displayed by black-and-white inversion processing of the lower half, for example, "LCTC-300" in the figure by the control code described above. To do.

When a print instruction is input from the input device 2 through the input control unit 4, the print control unit 26 requests the print character generation unit 28 to generate print characters. The print character generation unit 28 is the print control unit 26.
The character code and the control code are read from the character storage area 10 in response to the request from the user and transferred to the print data generation unit 30.

The changeover unit 32 is a font changeover switch of the input device 2.
When a font switching instruction is input to the switching control unit 12 through the input control unit 4 by 204, switching is performed by the support from the switching control unit 12. The switching unit 32 is switched so that the print data generation unit 30 reads the Mincho font from the display CG font 16 when the character read from the character storage area does not have a control code. When a character read from the character storage area 10 has a control code according to a font switching instruction from the font switching switch 204 of the input device 2, a Gothic font is printed. 32
Is switched to read a Gothic font from the print CG font 34.

Since the switching unit 32 switches between the Mincho typeface and the Gothic type by the control code, the print data generation unit 30 reads the format from the display CG font 16 or the print CG font 34 by normal font access, and the print buffer 36. Send to.

The print character generation unit 28 sends a print instruction to the print buffer 36 when the data in the print buffer 36 is completed for one line, and sends the data in the print buffer 36 to the printing device 38. Printer
38 prints, and when the printing of one line is completed, it outputs an end signal to the print control unit 26. The print control unit 26 is a printing device.
Unless a print end signal is input from 38, the print character generation unit 28 is requested to generate print characters to print the next line.

An example printed by the printing device 38 is shown in FIG. As shown in the figure, the "LCTC-300" portion is printed in Gothic font.

The operation for designating the character font will be described with reference to the flowchart shown in FIG.

When the cursor is stopped at a desired position from the input device 2 by the cursor movement key and an input is made by the font switching key (100), this input is sent to the control code control unit 6 through the input control unit 4. The control code control unit 6 controls the character edit control unit 8 to search and recognize the character at the current cursor position stored in the character storage area 10 (10
2) It is judged whether or not this character is already a control code (104), and if there is already a control code, the character before the corresponding character stored in the character storage area 10 through the character edit control unit 8 is judged. The control code is deleted (106), and if there is no control code before the character at the current cursor position, the control code is inserted (108). In this way, the data in the character storage area 10 is updated.

Next, the operation of displaying characters on the display device 24 will be described with reference to the flowchart shown in FIG.

When there is a display request by inputting the designation of the position of the character to be displayed from the input device 2 with the cursor movement key or the scroll pointer (110), this request is sent to the control code control unit 6 through the input control unit 4. The control code control unit 6 sends a display request to the character display control unit 14.

In response to the display request from the control code control unit 6, the character display control unit 14 generates the address of the character storage area 10 and reads the character code and control code stored in the character storage area 10 (112). The character display control unit 14 determines whether the read character data has a control code (114),
If there is a control code, the character font read from the display CG font 16 is output to the attribute control unit 18 and the attribute is set (116).

The character display control unit 14 further reads the corresponding font data from the display CG font 16 by the character code (118) and transfers it to the display data storage unit 20 (120).

Since the display CG font 16 stores Mincho font data, the display data storage unit 20 stores Mincho font data.

It is determined whether or not the font has an attribute (122), and if the font sent from the display control unit 14 has an attribute, the attribute control unit 18 sets the lower half of the character font for which the attribute is set to black and white. Inversion processing is performed (124) and output to the character display control unit 14.

The character display control unit 14 transfers the lower half sent from the attribute control unit 18 to the display data storage unit with the character font subjected to black and white inversion processing (126).

The character display control unit 14 outputs a display command to the display control unit 22 (128). In response to a display command from the character display control unit 14, the display control unit 22 reads the character font stored in the display data storage unit 20 and the character font whose lower half has been subjected to black and white inversion processing, and sends it to the display device 24. The display device 24 displays these characters as shown in FIG. 3 (a). That is, the characters that should be displayed in Mincho type are normally displayed in Mincho type,
Characters displayed in Gothic font are displayed in Mincho font, and the lower half is displayed in black and white by the control code.

It is judged whether or not the display is completed (130). If the display is not completed, the process returns to step 112, and the character code and the control code stored in the character storage area 10 are read again.

Next, the character printing operation will be described with reference to the flowchart shown in FIG.

When a print instruction is input from the input device 2 through the input control unit 4, the print control unit 26 requests the print character generation unit 28 to generate print characters (140). The print character generation unit 28 reads the character code and the control code from the character storage area 10 in response to a request from the print control unit 26 (142) and transfers them to the print data generation unit 30.

By inputting a font switching instruction to the switching control unit 12 through the input control unit 4 in advance by the font switching switch of the input device 2 to the switching unit 32,
In response to an instruction from the switching control unit 12, the font of characters with control codes is switched to have a Gothic font. That is, the switching unit 32 uses the print data generation unit 30 for the characters other than the characters specially designated with the control code.
Is switched to read a Mincho font from the display CG font 16, and a character specially designated with a control code is switched to read a Gothic font from the printing CG font 34.

Therefore, the print character generation unit 28 determines whether or not the character has a control code (144), and if there is no control code, generates a font address of Mincho typeface, and displays the CG phone 16 for display.
The font of Mincho type is read through the switching unit 32 from (146). If there is a control code, a Gothic font address is generated according to an instruction from the font switching key 204 of the input device 2 (148), and a Gothic font is read from the print CG font 34 (150).

When the switching unit 32 is switched in this way, the print data generating unit 30 uses the normal font access to display CG.
The font is read from the font 16 or the CG font 34 for printing and sent to the print buffer 36 (152).

The print character generation unit 28 determines whether the data in the print buffer 36 is complete for one line (154), and when one line is complete, sends a print start instruction to the print buffer 36 (156), and the print buffer 36 And sends the data in the printer 38. If the data in the print buffer 36 is not complete for one line, the process returns to step 142 and the print character generation unit 28 is requested again to generate print characters.

The printing device 38 performs printing, and when printing of one line is completed, outputs an end signal to the print control unit 26. Print control unit
26 determines whether or not a print end signal is input from the printing device 38 (158), and if not input, returns to step 142 to generate a print character in the print character generation unit 28 to print the next line. Request.

An example printed by the printing device 38 is shown in FIG. As shown in the figure, the "LCTC-300" portion is printed in Gothic font.

As described above, the font displayed on the display device 24 is the Mincho font as shown in FIG. 3A, and the lower half of only the portion to be printed in the Gothic font is displayed in black and white. Therefore, the operator can see the portion of the characters displayed on the display device 24 which is displayed in black and white in reverse, and can determine that this portion is displayed in Gothic font and the other portion is displayed in Mincho font.

Conventionally, when displaying on the display device 24, as shown in FIG. 4 (a), a control code 50 is inserted before a character to display a font, and this is printed as shown in FIG. 4 (b). Was.
Therefore, since the arrangement of the characters displayed on the screen and the characters printed is shifted by the insertion of the control code 50, the number of characters and the character spacing between the characters actually printed and the characters displayed on the display device 24 may be different. There was a difference, and it was not possible to judge the appearance of the printed characters from the display on the display device 24.

On the other hand, according to the present embodiment, since the control code is not displayed, it is possible to accurately determine the image such as the number of characters to be printed or the character spacing on the display screen.

Further, in the display screen of the display device 24, the lower half of the characters of different fonts is displayed in black and white, so that the portion displayed in Gothic can be easily identified.
Moreover, since it is not necessary to search for the inserted control code to determine the character style, it is possible to easily distinguish the character portions having different character styles even when scrolling on a small screen.

Since the characters to be printed in Gothic font are displayed in reverse on the display device 24, there is no need to provide a switching circuit as in the case of providing a font switching circuit to switch and display the fonts, which is inexpensive.

The font instruction can be given for each character, and it is easy to change the font instruction once specified by inputting the control code later.

FIG. 5 shows another embodiment of the character string processing device according to the present invention.

In this embodiment, for display CG font 16, for printing
In addition to the CG font 34, a CG font 40 that stores fonts of different fonts is provided. In addition to the switching control unit 12, a switching control unit 13 is provided between the input control unit 4 and the switching unit 32. The other components are similar to those of the embodiment shown in FIG.

In this device, as shown in FIG. 6, the input device 2
In addition to the font changeover switch 204 described above, a base font changeover switch 206 is provided. The font changeover switch 204 is, as shown in FIG.
It can be switched between Mincho type and others. Other fonts are CG
It is stored in font 40.

When the font changeover switch 204 is set to, for example, a Gothic font, this instruction is sent from the input device 2 to the changeover unit 32 through the input control unit 4 and the changeover control unit 13, and the print data generation unit 30 is changed to the changeover unit 32. CG for printing through
A Gothic font is read out from the font 34, and characters with control codes are printed in Gothic font.

The base font changeover switch 206 is also changed over between the Gothic type, the Mincho type, and the like, as shown in FIG.
When the base font changeover switch 206 is set to, for example, Mincho type, this instruction is sent from the input device 2 to the changeover unit 32 through the input control unit 4 and the changeover control unit 12, and characters without a control code Printed in Mincho. That is, it indicates that the base character font that is not given the attribute by the control code is the Mincho typeface.

Therefore, in this case, when there is no control code in step 144 as shown in FIG. 10, after the base font is specified in Mincho by the base font changeover switch 206 in step 147, the print data generation unit 30
Reads the Mincho font from the display CG font 16 through the switching unit 32. The other operation of FIG. 10 is shown in FIG. 9 (c).
Is the same as

According to this embodiment, not only the font changeover switch 204 can indicate the font in which the characters with the control code are printed, but also the base font changeover switch.
By 206, it is possible to specify the printed font of the characters without the control code. Therefore, from among the three types of fonts shown in FIG. 5, it is possible to specify at the time of printing which font to use for printing the base font and the font to which attributes have been added by the control code. A wide range of fonts to choose from.

FIG. 7 shows still another embodiment of the character string processing device according to the present invention.

In this embodiment, the components of the functional block diagram shown in the figure are the same as those in the embodiment of FIG.

In this device, as shown in FIG.
The font changeover switch 204 is adapted to switch between Mincho typeface and Gothic typeface, for example. When the font changeover switch 204 is switched to Mincho type, the base font is set to Mincho type, and characters without a control code are printed in Mincho type. A character with a control code is printed in a Gothic font that is the reverse of what the font switch 204 indicates.

Therefore, when there is no control code in step 144 of FIG. 11, after the base font is designated as Mincho by the font changeover switch 204 in step 147, the print data generation unit 30 causes the changeover unit 32 to display CG for display. Read Mincho font from font 16.

If there is a control code in step 144, a gothic font address is generated by a font reverse to the base font specified by the font changeover switch 204 in step 149, and the gothic font data is output from the printing CG font 34. Read (150). Other operations are the same as in FIG. 9 (a).

In this embodiment, the switching instruction from the switching control section 12 and the reading instruction by the control code from the print data generating section 28 are both binary instructions of "1" and "0". To be selected.

According to this embodiment, the base font can be easily switched.

In each of the above embodiments, the font is converted between Mincho and Gothic, but it is also applicable to other fonts such as bold circle Gothic, italicized characters, and outlined characters. It is also possible to store Taimaru Gothic in the CG font 34 for use and convert between Mincho typeface and Taimaru Gothic by a control code.

Further, although the font conversion is performed by switching the CG font in the above-described implementation, the font conversion may be performed by switching by the font conversion algorithm such as conversion from Mincho typeface to Gothic typeface.

Effect According to the present invention, it is possible to select and designate the font of the character to be printed by the font designating means provided in the printing means, and to judge the character of different font to be printed by the attribute of the character displayed on the display means. can do.

Moreover, since the character attributes can be easily specified and changed, it is easy to change the character to have a different font.
