Abstract

PURPOSE:To permit a Japanese text and an English text to exist in a mixed state and thereby improve a printing balance during their coexistence by seeking a printing area for Japanese font that remains from the printing length of a single line and the printing length of English font, and equally allotting Japanese characters to the printing area for Japanese font. CONSTITUTION:The number l of printing dots of a single line is sought by an arithmetic and logic operation based on previously set printing format data, and an English text which exists in a mixed state in printing data of a single line is detected to obtain the length le of printing dots in a single line by arithmetic and logic operation. Then a character pitch for each Japanese text character of printing data in a single line is sought based on a calculation equation l-le/number of Japanese characters = S and at the same time, the number of residual dots(a) is sought as well. These are allotted to each Japanese text character of printing data in a single line, and the allotments are set in a character pitch table in RAM 11. The character pitches decided for Japanese and English text characters are written into the character pitch table of the RAM11. Later, a character pattern of printing data of a single line is developed in accordance with the set contents of the character pitch table and a single line of data is printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device equipped with dedicated character fonts for Japanese and English texts.

(Prior Art) Most of the recent document creation devices, such as Japanese word processors, have special character fonts for English text in addition to character fonts for Japanese text, and are designed so that they can also be used as English word processors. ing. However, in most of these, Japanese or English is selected at the initial stage of input or printing, and the free mixing of Japanese and English is restricted. This is due to the difference in character font size (width) between Japanese and English.

Furthermore, it is possible to simply develop a print pattern using each character font when Japanese and English texts are mixed, but in this case, there is a problem that the print balance of the entire document becomes poor.

(Problems to be Solved by the Invention) As mentioned above, in conventional document creation devices equipped with character fonts for Japanese and English, the free mixing of Japanese and English is restricted and impossible. Even if they were mixed together, there was a problem that the overall printing balance was poor.

The present invention enables mixed printing of Japanese and English texts, and
It is an object of the present invention to provide a document creation device capable of achieving good printing balance when mixed characters are mixed.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a method for determining the print length for one line of character data to be printed in a document creation device equipped with a Japanese character font and an English character font. a first calculation means for calculating by calculation, a means for detecting a character to be printed in an English font from among the character string in one line, and a second calculation for calculating a print length in the English font detected by this means. and allocation means for equally allocating Japanese characters to the remaining Japanese font printing areas in one line based on the calculation results of the first and second calculation means.

(Function) In print mode, when printing is instructed, the print length of one line is calculated from the basic character pitch for one line of print data containing both Japanese and English text, and the character string of the one line is calculated from the basic character pitch. The print length of the characters to be printed in the English font is calculated from among the characters. Furthermore, the printing area of the remaining Japanese font in one line is calculated from the printing length of one line and the printing length of the English font, and Japanese characters are evenly allocated to the printing area of this Japanese font. As a result, it becomes possible to mix Japanese and English texts, and it is possible to achieve a good printing balance when they are mixed.

FIG. 2 is a flowchart showing the print control operation for a mixed Japanese and English document according to the above embodiment.

FIGS. 3 and 4 are diagrams showing display examples and printing examples for explaining the operation in the above embodiment.

Here, the operation in one embodiment of the present invention will be explained with reference to the above-mentioned FIGS. 1 to 4. First, for example, in Figure 3 (a
An example of printing the first line of the Japanese-English mixed document shown in ), "The recent development of Coa+putar 5science is alarming" will be described. In this case, the basic character font and format are: Japanese font: 24 (vertical) x 24 (horizontal) dots English font: 24 (vertical) x 18 (horizontal) dots (compatible with proportional spacing) Japanese basic characters pitch 20 dots 1 line printing Number: 20 characters.

When one line printing is instructed in print mode, the print control operation shown in the flowchart of FIG. 2 is started under the control of CPU10.

First, the CPU 10 reads one line of the document to be printed from the RAM 11 to the printer interface 24, and calculates "(basic character pitch) x (number of characters per line)" based on the print format data set in advance. Then, the number of printed dots in one line is determined (step Sl). In this case, the basic character pitch is 30 dots and the number of characters per line is 20, so the number of printed dots per line is r30x20-600.
(dot)".

Next, English sentences mixed in the one line of print data are detected and the dot length Je thereof is calculated (step S2). The detection of the above English text is a half-width character if it is an alphabetic character,
Determine it as an English font regardless of full-width characters. In this case, the English sentence is r Coff1 as shown in Figure 3(a).
puter 5c1ence J uses a total of 9 digits from the 4th digit to the 12th digit in one line and is displayed in half-width characters, so the number of characters is equivalent to 18 characters including spaces. The basic horizontal dot of English fonts is 18.
However, as shown in the printing example in Figure 4(a), the characters rt and rJ in the above English sentence are 16 dots, and the character riJ is 14 dots, so the total dot length e is r.
18X18-8-316 (dot).

Next, using the calculation results of steps St and S2 above, calculate "no no e/number of Japanese characters - 8 (quotient)" to find the character pitch for each Japanese character in one line of print data, and calculate the number of remaining dots. Find a (step S3). The number of printed dots in one line above is 600 dots, and the dot length of the English printed part is l! Since e is 316 dots and there are 11 Japanese characters, the number of dots per Japanese character is S.
is r (Coo -318)/11-25...remainder 9. Then, the remaining number of dots a is allocated to each Japanese character in the above one line of print data, and the RA
Set in the character pitch table in M11 (step S4). The above-mentioned surplus dot number a is allocated, for example, one dot at a time from the beginning of the line, or by giving priority to kanji over hiragana. Now, if the number of remaining dots a is allocated from the beginning of the line, if the number of remaining dots is ``9'' as described above, the character pitch is ``26 dots'' from the beginning to the 9th character of the Japanese character, and the character pitch is ``26 dots'' at the end. The two characters become "25 dots". The character pitch for each character in Japanese and English characters determined as above is determined by RAMI.
Written to the character pitch table in I.

Thereafter, the character pattern for the one line of print data is developed on the line buffer in the printer interface 24 according to the setting contents of the character pitch table (step S5), and according to the data held in this line buffer, the character pattern shown in FIG. One line is printed as shown in (step S6). In addition, the symbol (■) in FIG. 3A shows an example of printing when, in step S4, the remaining number of dots a is allocated with priority given to kanji over hiragana.

Next, a case will be described in which the first sentence in the Japanese-English mixed document shown in FIG. 3(b) is printed: ``The recent development of computers is alarming.'' As described above, in the print mode, by instructing execution of one line printing, the print control operation shown in the flowchart of FIG. 2 is started under the control of the CPU 1O.

First, in step S1, 1
Number of printed dots per line: r30x20-600 (dots)
is required. Next, the English text mixed in the above line of print data is detected and its dot length θ is calculated by calculation (step S2), but the English text in this case is as shown in FIG.
), the full-width rcomputerJ has 8 characters. The letters rt and rJ in the above English sentence have 16 dots, which is 2 dots less than the basic number of dots in the horizontal direction, so the total dot length of the English sentence is e.
is r18X8-4-140 (dot).

The number of printed dots in one line is 600 dots, the dot length of the English printed part, 17e, is 140 dots, and the number of Japanese characters is 12 including spaces, so by the calculation in step S4, one Japanese character is The number of dots S to hit is
r (600-140) /12-38...remainder 4"
is required. When the number of remaining dots a is allocated in step S5, if the number of remaining dots a is allocated from the beginning of the row, the number of remaining dots is ``4'' as described above.
'', the character pitch is ``39 dots'' for the first four characters of the Japanese characters, and ``38 dots'' for the other characters.

The character pitch for each character in Japanese and English characters determined as described above is written to the character pitch table in RAMII.

After that, the character pattern for the one line of print data is created in RAM according to the settings of the character pitch table.
Expand it on the line buffer in II (step S5),
According to the data held in this line buffer, FIG. 4(b)
One line is printed as shown in (step S6).

In the above embodiment, the case where one line printing is performed is also explained, but even when printing a plurality of lines, it can be carried out in the same manner as in the above embodiment.

[Effects of the Invention] As detailed above, according to the present invention, in a document creation device equipped with a Japanese character font and an English character font,
Calculate the printing of one line from the basic character pitch for one line of print data containing a mixture of Japanese and English text, and also calculate the printing of characters to be printed in English font from the character string of the above one line. , Furthermore, the remaining Japanese font printing area in one line was determined from both the printing of one line and the printing of the English font, and the Japanese characters were evenly allocated to the printing area of this Japanese font. This makes it possible to mix Japanese and English texts, and also to achieve good printing balance when they are mixed, and to align the right ends of lines.
