Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a document creation device such as a word processor, and more particularly to a document creation device that creates a document by editing a text containing a mixture of Japanese and European texts.

<Prior art> Conventionally, document creation devices called Japanese word processors are capable of inputting Japanese and European characters, but when editing a text containing a mixture of Japanese and European characters, editing control is usually performed in the Japanese document style. Therefore, editing processing unique to European languages could not be applied to the European language lines. The same applies when creating a document using a printing device.

In other words, in the memory of a printing device, European characters and Japanese characters generally have different dot matrix structures for one character (Japanese characters have a larger dot matrix structure except for symbols), and Japanese characters may appear in the print line of a European text. Even if there are a mixture of these, they are uniformly memorized. As a result, the positions of the characters at the top and bottom of successive printed lines are uneven, resulting in a document that is difficult to read.

<Purpose> The present invention has been improved so that when creating a document containing a mixture of Japanese and European texts, the document can be created in a way that is easy to read and beautiful.

In order to achieve the above object, the present invention provides a document creation device with a character data input means for inputting Japanese character data and European character data, and a character data storage means for storing the character data input from the character data input means. a Roman font selection means for selecting a Roman font to be input from the character data input means; a font information storage means for storing font information selected by the Roman font selection means; and character spacing for each Roman font. A character spacing storage means for storing the number of dots, a character pattern storage means for storing Japanese character patterns and European character patterns for each typeface in a dot matrix configuration of different sizes, and a typeface stored in the typeface information storage means. Based on the information, the number of horizontal dots and the number of dots between characters and the number of horizontal dots of European characters of the selected typeface are read from the character spacing storage means and the character pattern storage means, and the number of horizontal dots and the number of horizontal dots of European characters are read out. Japanese character spacing dot number setting means for setting the number of dots obtained by subtracting the horizontal dot number of Japanese characters from an integral multiple of the character spacing formed by the character spacing dot number as the character spacing dot number of Japanese characters; and the character spacing storage means. and according to the dot matrix and the number of inter-character dots of the European characters and the dot matrix of the Japanese characters stored in the character pattern storage means, and the number of inter-character dots of the Japanese characters set by the Japanese character inter-character dot number setting means, By providing a printing means for printing character data in which Japanese characters and European characters are mixed and stored in the character data storage means, one character interval consisting of the number of horizontal dots of Japanese characters and the number of inter-character dots can be adjusted to It can be set to an integer multiple of the character interval, which is the number of dots and the number of dots between characters, so that the positions of the printed characters on the top and bottom lines of consecutive print lines containing a mixture of Japanese and European characters are aligned with each other, and the printing condition is improved. This makes it possible to obtain an orderly and beautiful document.

<Embodiment> FIG. 1 is a block diagram showing the configuration of a document creation device of the present invention.

Reference numeral 1 denotes an input device comprising a keyboard having character keys for Japanese and European languages, language mode indicating means for indicating whether the input language is Japanese or European, and various editing keys.

2 is a main control unit (CPU) that controls the entire device and executes editing processing according to Japanese or European text.
Various input information from the input device 1 is introduced.

Reference numeral 3 is a document memory for storing input Japanese or European text and format information; 4 is a document memory in which the text data to be displayed from among the text data stored in the document memory 3 is patterned by a display character generator (not shown); Display that pattern data
The display device 5, such as a CRT, is a printing device that converts text data transferred from the text memory 3 into a print pattern and records it, and prints Japanese characters and European characters in dot configurations of different sizes.

The printing device uses Pica characters as European character typefaces.
It is possible to record in multiple fonts such as elite characters, and for example, this character dot configuration is A in Figure 2.
As shown in Figure 2, pica characters are made up of an axb matrix, or a 24x15 dot matrix, with inter-character dots c, and Japanese characters are made up of an axd matrix, or a 24x dot matrix, as shown in B in Figure 2. It consists of 24 dot matrices and a dot e between characters. Furthermore, although the elite characters of European characters are not shown, they are composed of, for example, a 24×17 dot matrix and a dot f between characters. The pitch of the letters is different between the European script fonts, Paika and Elite.

Therefore, when printing, this printing device 5 is instructed in advance to select a font for European characters, and prints in the designated font, and also prints Japanese characters in the matrix configuration described above.

6 is a character dot number table that stores the number of vertical dots and the number of horizontal dots in the character matrix of each of a plurality of fonts for Japanese characters and European characters, and the number of intercharacter dots c and f for each font for European characters. During printing, the main control unit (CPU) controls the printing device 5 by referring to the data in the table 6.

Next, the print control operation of the document creation apparatus having the configuration shown in FIG. 1 will be further explained below with reference to the flowchart shown in FIG. 3.

Now, character information containing a mixture of Japanese and European characters is inputted from the input device 1, and this inputted text data is edited and stored in the text memory 3.
When the text data is to be printed to create a document, a printing instruction is first given, and in the case of European characters, the font is also given.

Then, the printing operation begins, and the character data retrieved from the text memory 3 during this printing is first judged by the main control unit (CPU) 2 as to whether or not it is a Latin character (step S in Figure 3). ₁ ),
If it is a Roman character, character dot number table 6
For example, if Pica characters are specified, the printing device 5 is controlled to print the first character (step S ₂ ) according to the character dot information and spacing dot information of the Pica characters. The printing head is moved only by the character spacing dot c (step _S3 ), and the printing cycle for one character is completed. If European characters continue, the printing cycle is repeated to continue sequential character printing.

Next, when a Japanese character is retrieved from the text memory 3, it is determined that it is a Japanese character (step S ₁ ), and then from the character dot number table 6, the font of the specified European character and this character are determined. In the example, data on the number of horizontal dots b in the character matrix of pica characters, data c on the number of dots between characters, and data d on the number of horizontal dots in the character matrix of Japanese characters.
The number of dots between characters of the Japanese character is calculated (step _S4 ). This calculation calculates the number of dots between characters in a Japanese character so that the sum of the number of horizontal dots d and the number of dots between characters is exactly twice the number of horizontal dots and the number of dots between characters in the font of the European character. calculate.

In other words, if the number of dots between characters in Japanese characters is e, the number of horizontal dots in Japanese characters is d, the number of horizontal dots in Pica characters is b, and the number of dots between characters in Pica characters is c, then e=2×(b+c)−d. and calculate the number of dots between characters. This sets the character spacing between Japanese characters and this inter-character space to be twice the character interval between European characters and this inter-character space.

Thereafter, the printing device 5 is controlled according to the character dot information of the Japanese characters and the character spacing information obtained by the calculation, and the characters are first printed (step S ₄ ).
Thereafter, the printing head is moved only for the dots between characters (step _S6 ), and the printing cycle for one character is completed. If Japanese characters continue, the printing cycle is repeated and printing continues in sequence.

As described above, the text data containing a mixture of European and Japanese texts in the text memory 3 is printed by the printing device 5 and created as a document.

This created document has a difference in the horizontal size of Japanese characters (the sum of the number of horizontal dots in the character matrix and the number of dots between characters) compared to the horizontal size of European characters (the sum of the number of horizontal dots in the character matrix and the number of dots between characters). The sum of numbers) is exactly doubled, and therefore the positions of the printed characters in the upper and lower lines of successive printed lines are aligned even if European and Japanese characters are mixed, resulting in an easy-to-read document.

In the example above, the Pica font is selected as the Roman character, but if elite characters are selected, the dot count data for elite characters is extracted from Table 6 and controlled in the same way as above. .

In the above example, the number of dots between characters of Japanese characters is calculated, but the number of dots between characters corresponding to pica characters and elite characters is calculated in advance and stored in Table 6 above. If the characters to be memorized are Japanese characters,
It is also possible to extract corresponding dot number data from the table 6 according to the specified typeface.

Further, although a plurality of fonts can be selectively printed as the printing fonts of European characters by the printing device, it is of course possible to print only one predetermined font of European characters.

Furthermore, in the case of symbols related to Japanese characters, in other words, even when printing symbols composed of dot matrices smaller than the dot matrix of Japanese characters, the number of horizontal dots and the number of inter-character dots by the character matrix of this symbol are It is more preferable to adjust the number of inter-character dots of the symbol so that the sum is equal to the sum of the number of horizontal dots and the number of inter-character dots in the character matrix of Roman characters.

<Effects> As described above, the document creation device of the present invention includes a character data input means for inputting Japanese character data and European character data, and character data for storing character data input from the character data input means. a storage means; a European font selection means for selecting a European font to be input from the character data input means;
a font information storage means for storing font information selected by the European font selection means; a character spacing storage means for storing the number of dots between characters for each European font; a Japanese character pattern and a Roman character pattern for each typeface. and a font selected from the character spacing storage means and the character pattern storage means, depending on the font information stored in the font information storage means. Read the number of horizontal dots and the number of inter-character dots of the European characters and the number of horizontal dots of the Japanese characters, and calculate the number of horizontal dots of the Japanese character from the integral multiple of the character interval, which is the number of horizontal dots and the number of inter-character dots. Japanese character spacing dot number setting means for setting the subtracted number of dots as the character spacing dot number of Japanese characters; and a dot matrix and character spacing dot number of European characters stored in the character spacing storage means and the character pattern storage means. Printing character data containing a mixture of Japanese and European characters stored in the character data storage means according to a dot matrix of Japanese characters and the number of dots between Japanese characters set by the number of dots between Japanese characters setting means. By providing a printing means, the character interval consisting of the number of horizontal dots and the number of inter-character dots for Japanese characters can be set to an integral multiple of the one-character interval consisting of the number of horizontal dots and the number of inter-character dots for European characters, As a result, when creating a document by editing a text containing a mixture of Japanese and European texts, the positions of the characters at the top and bottom of consecutive print lines are aligned, making it possible to record the characters in an orderly manner, making it easier to read. It also has the characteristic of producing beautiful documents.
