Abstract

PURPOSE:To attain the input of Roman characters just with the use of a KANA (Japanese syllabary) conversion key by delivering the KATAKANA (square form of Japanese syllabary) of em or half-em in response to the input Roman character when the KANA conversion key is pressed again. CONSTITUTION:An alphameric key is depressed and then a character key is depressed in an em Roman character input state where half-em key is not depressed. Thus the input Roman characters with em 'WATASHI' are stored successively in an input character code memory 5 and displayed at a display part 17. When a KANA conversion key is drepressed, the width and the type of the input character are decided and '0' and '00' are stored in a character width register 8 and a character type register 7 respectively. Then the input character code is converted into an intermediate code at a converting part corresponding to said character width and type, i.e., an em Roman character intermediate code converting part 14 in a converting part 10. The converted intermediate code is stored in an intermediate code memory 6. In the case of a Roman character, the intermediate code is converted into HIRAGANA (cursive form of Japa nese syllabary) since the contents of a designating register 9 are kept at 0. Thus 'WATASHI' is displayed at a display control part 16 in HIRAGANA.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a kana conversion method for converting Roman character input into katakana in a word processor.

(b) Conventional technology Conventionally, in word processors, Japanese Patent Application Laid-Open No. 59-10
As disclosed in Publication No. 8137, it is equipped with a display means, a kana conversion key, and a romaji-kana conversion means, displays the input romaji on the display means, and converts the input romaji in response to the press of the kana conversion key. There was something that converted it into katakana or hiragana. As for this kana conversion key, there are two types: one where the katakana conversion key and the hiragana conversion key are independent, and the other where the katakana conversion key and the hiragana conversion key are both independent.

When converting Roman characters to Katakana, such word processors output full-width Katakana if all full-width Roman characters could be input, and half-width Katakana if all half-width Roman characters could be input.

(c) Problems to be solved by the invention For operators who are familiar with English quib writers,
Even when inputting kana, it is easier to key in romaji than hiragana or katakana, and for this reason, the romaji kasu conversion function is often used.

However, as shown in Figure 3, when writing a full-width katakana key within a table frame (1) surrounded by ruled lines, the conventional
If you input full-width Roman characters in order to output full-width Katakana characters on a doprocessor, even if the number of full-width Katakana characters you want to write is enough to fit in the table frame, the number of input characters will be approximately twice that of full-width Roman characters. , Figure 3 (
As shown in b), the table frame (1) expands. After that, when you press the kana conversion key, the entered full-width Roman characters are converted to the desired full-width katakana, as shown in Figure 3 (c), but the table frame (1) becomes an expanded yoma.
It was necessary to move the ruled lines (2) and return the table frame (1) to its original thickness.

On the other hand, if you enter half-width Roman characters, the table frame will not expand, but the conversion result will be half-width katakana, so use the cursor keys, edit keys, and kana conversion keys to convert half-width katakana to full-width katakana. It was extremely troublesome.

(d) Means for Solving the Problems The present invention provides that when the character width of the input Romaji is half-width, in response to pressing the kana conversion gee mentioned in iii. output katakana,
When the kana conversion key is pressed again following the pressing, full-width or half-width katakana corresponding to the input Roman characters is output.

(1+) Effect In the present invention, when inputting the total angle force in the table frame,
All you have to do is manually convert half-width Roman letters and press the kana conversion key once or multiple times in succession.
Half-width katakana can also be obtained by simply pressing the kana conversion key.

Figure 2 is a block diagram showing the configuration of a word processor according to the present invention, and Figures 1 (a) and (b) are flowcharts showing an example of the present invention. A case will be explained in which conversion and conversion to hiragana are realized using only one kana conversion key.

In Figure 2, (3) is an alphanumeric key, a hiragana key, a katakana key, a half-width key, and a kana conversion key.

A keyboard equipped with a kanji conversion key, a non-conversion key, multiple character keys, a cursor key, etc., (4) is a control unit, (5)
and (6) are an input character code memory and an intermediate code memory that store input character codes and converted intermediate codes, respectively; 7) and (8) are character type registers and character type registers that store the character type and character width of input characters; Character width register (9) is a specification register that stores the character type to be converted into kana next, (10
) is a hiragana intermediate code converter (11), a full-width katakana intermediate code converter (12), a half-width katakana intermediate code converter (13), a full-width roman intermediate code converter (14)
), a half-width Roman alphabet intermediate code converter (15), (16) a display control unit, and (17) a display unit.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

When alphanumeric keys are pressed and half-width keys are not pressed, when a character key is pressed, the input double-width Roman letters 'WATASHI' are input.

are sequentially stored in the input character code memory (5) and sent to the display control section 16), where they are displayed on the display section 17).
It can be displayed with .

Therefore, when you press the kana conversion key, the character width and character type of the input character are determined, and the results are stored in the character width register (8) and character type register (7), respectively. be remembered. Of the converting section (10),
The input character code is converted into an intermediate code by a conversion unit corresponding to these character widths and character types, that is, a full-width Roman character intermediate code conversion unit (14), and the converted code is stored in an intermediate code memory (6).

In the case of Roman characters, the content of the designation register (9) remains rO'', so the intermediate code is converted to hiragana by the conversion unit (11) and output to the display control unit (16). Therefore, the input full-width Roman alphabet 'WATASHI' is converted into hiragana 'WATASHI' and displayed on the display section (17).

Subsequently, when you press the kana conversion key, the contents of the specified register (9) are reversed to ``r1'' when converting to hiragana, and the contents of the character width register (8) are ``0'', so
The intermediate hood is converted into full-width katakana by the converter (12), and ``Watasho'' is displayed. At this time, the contents of the specified register (9) are inverted to 10'', so when you press the kana conversion key again, it becomes hiragana, and from then on, each time you press the kana conversion key, hiragana and full-width katakana are displayed. Ru. In other words, the operation is exactly the same as the conventional one, and in the case of input to the table frame (1), it becomes as shown in FIG. 3 (c).

However, when you press the half-width key and input the half-width Roman letters 'WAI'ASHI' into the table frame (1), all of the entered half-width Roman letters are displayed in the table frame (1), as shown in Figure 4 (A).
1), and the table frame (1) is enlarged, i.e.,
Movement of ruled line (2) does not occur.

Therefore, when you press the kana conversion key, the character width register (
8) and character type register (7) are "rl" and roo, respectively.
", and the half-width Roman intermediate code converter (15
), the input character code is converted into an intermediate code, and since the designated register (9) is "0", this intermediate code is converted into hiragana by the converter (11). For this reason,
As shown in FIG. 4 (b), the hiragana character "watashi" is displayed within the table frame (1).

In this state, if you press the kana conversion key again, the contents of the specified register (9) will be reversed to ``11'', and the contents of the character width register (8) will also be ``IJ, so the intermediate code will be converted by the converter (13).'' It is converted to half-width katakana, and as shown in FIG. 4(c), half-width katakana 17 decimal is displayed in the table frame (1). Then, following this press,
In this case, when you press the kana conversion key, the character type register (
7) and character width register (8) are respectively 'oo
, and "1", the intermediate code is converted to full-width katakana by the converter (12), and "full-width katakana 1 watashi" is displayed in the table frame (1), as shown in Figure 4 (d). That will happen.

In this way, full-width katakana can be written in the table frame (1) by inputting Roman characters without enlarging the table frame (1).

If the kana conversion key is pressed again after full-width katakana is displayed, hiragana will be displayed, and thereafter, half-width katakana, full-width katakana, and hiragana will be repeated each time the key is pressed.

Incidentally, in the above-described embodiment, half-width katakana is output first, and then full-width katakana is output, but the output may be output in the opposite manner. Furthermore, although an example has been described in which conversion to hiragana and katakana is realized using only one kana conversion key, the present invention is also applicable to cases where the katakana conversion key is provided independently of the hiragana conversion key. , in this case, the designation register (9) is unnecessary. A main flowchart of this example is shown in FIG.

(g) Effects of the Invention According to the present invention, when writing full-width katakana in a table frame, by simply using the kana conversion key, it is possible to input Roman characters without enlarging the table frame, thereby saving space. The advantage of half-width Roman alphabet input is fully utilized, making it extremely convenient.
