Abstract

PURPOSE:To simply correct the specifications of Roman character/KANA (Japanese syllabary) conversion by using a means which designates a new rule different from the Roman character/KANA conversion rule decided previously. CONSTITUTION:A Roman character/KANA converting circuit 42 converts Roman characters inputted from an input device 1 into KANA characters based on rule information given from a Roman character/KANA conversion table memory part 43 or a change contents memory part 45. The circuit 42 neglects the prescribed rule information stored in the part 43 in case a new rule is designated by a Roman character/KANA conversion rule changing circuit 44. Then the circuit 42 performs the Roman character/KANA conversion based on the new rule stored in the part 45. Then the KANA characters obtained through the Roman character/KANA conversion are displayed on a display device 2 via a display data production circuit 46.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to devices having character processing functions such as word processors, office computers, personal computers, data processors, and workstations (hereinafter referred to as "character processing devices"), and in particular, to Concerning kana conversion processing.

A character processing device such as a word processor that is equipped with an input device and a display device generally uses Romaji, which converts the alphabet input from the input device into Japanese kana characters and displays it, as a means of inputting Japanese. Although it has an input function,
If you look into each company's products, you will find that the rules (specs) for converting Roman characters to Kana characters vary from company to company.

When introducing products from different manufacturers, the differences in the rules for converting Romaji to Kana, which are the basis for Romaji input, were quite a hindrance to use, and it was inevitable that input efficiency would drop considerably until the users got used to the new rules.

Regarding romaji-kana conversion, only one rule is adopted for each product, and there are no products that have multiple romaji-kana conversion rules or that have variable rules.

Therefore, as shown in FIG. 12, there are some parts where the rules differ depending on the product.

For example, when entering "Hello", the model number ■ is r.
Enter HANNIJ in romaji. However, if you enter romaji in the same way with ■, it will be converted to "hanni". To input "hani" in ■, it is necessary to input "HANIJ" in romaji, which is converted to "hani" in ■.

Also, the sounds (A, I, U, E, O, Katana, Ri.

y, yu, yo, tsu, wa) can also be changed by shift switching.
There is a rule of ``X'' and a rule of ``■'' which adds "X".

Furthermore, for the model numbers ■ and ■, even if you input rDUJ, it will be converted to "zu" for the model number, and "do" for the model number ■.

These are just some of the differences, but if the input of characters such as "n" and "Yo" that frequently appear when inputting Japanese is different, input errors will occur frequently if you use a product with rules different from those you are used to. do.

Currently, there are no rules similar to JIS for Romaji input rules, and it is thought that they will become more and more dispersed in the future. Therefore, the user has no choice but to follow each rule, which poses an enormous burden.

Purpose This invention has been made in view of the above points.
The purpose is to reduce the disadvantages when migrating to another model, and to allow users to create their own simple specifications to improve operability.

In order to achieve the above object, the present invention provides a character system which is provided with an input device and a display device, and has a function of converting Alphabella 1 to Japanese inputted from the input device into Japanese kana characters. In the processing device, a conversion rule changing means for specifying a new rule different from a predetermined romaji-kana conversion rule, a change content storage means for storing the rule changed by the conversion rule changing means, and a conversion rule changing means. When a new conversion rule is designated by , the Romaji conversion means ignores the predetermined conversion rule and performs Romaji-kana conversion based on the new conversion rule.

Roman character conversion table storage unit 43. It is composed of a Roman character conversion rule change circuit 44, a change content storage section 45, and a display data creation circuit.

Next, the functions of each of these components will be briefly explained.

The input device 1 includes the keyboard (
(hereinafter referred to as an "input device") to input characters, etc.

The next process determining circuit 41 determines the current state based on the data input from the input device 1, and outputs an input code to each circuit.

The Roman character conversion circuit 42 is a Roman character conversion means by the microcomputer 21 shown in FIG. Convert to

Note that when a new rule is specified by the Roman character conversion rule change circuit 44, this Roman character conversion circuit 42 ignores the predetermined rule information stored in the Roman character conversion table storage section 43 and changes the changed content. Romaji-kana conversion is performed based on the new rules stored in the storage unit 45.

The Roman character conversion table storage unit 43 stores a table of all combinations of Roman character to kana conversion according to predetermined rules, such as those shown in FIGS. 4 and 5, for example.

This uses a predetermined area in the ROM 22 shown in FIG.

The data format of this Roman character conversion table is composed of a data length, a Roman character notation, and a kana part to be converted thereto, as shown in FIG.

The Roman character conversion rule change circuit 44 is connected to the microcomputer 21 in FIG.
This is a conversion rule changing means by the user, and is responsible for the user specifying new Roman character conversion rules.

Then, the content of the specified Roman character conversion rule is stored in the change content storage unit 45 (RA in FIG. 5), which is a change content storage means.
(using a predetermined area of M23).

The display data creation circuit 4 creates pattern data necessary for display based on the code of the display character string given from the Roman character conversion circuit 42 and the Roman character conversion rule change circuit 45. This data is then displayed on a liquid crystal display device (hereinafter referred to as "display device") 2.

Next, the Romaji-kana conversion process according to this embodiment will be explained according to the flowchart shown in FIG.

When there is a key input from the input device 1, it is determined whether or not the Roman alphabet input mode is entered. If the mode is not Romaji input mode, proceed to other processing.

If it is the Roman character input mode, the Roman character conversion circuit 42 by the microcomputer 21 shown in FIG. 3 first searches the change content storage section 45 for the rule change table for Roman character conversion. and,
If there is a pattern based on the applicable rules, output the corresponding kana character code to the display data creation circuit 4B,
A kana character string is displayed on the display device 2.

If there is no corresponding pattern, the Roman character conversion table in the Roman character conversion table storage section 43 is searched, and if there is no corresponding pattern, error processing is performed.

If a corresponding pattern is found, the corresponding kana character string is displayed in the same manner as described above.

Next, with reference to the flowchart of FIG. 8, a description will be given of the Roman character conversion rule changing process in which the Roman character conversion rule changing circuit 44 of FIG. 1 creates a new Roman character conversion rule designated by the user.

The rule change table in the change content storage section 45 has the same data format as the Roman character conversion table storage section 43 (the Roman character conversion table shown in FIG. 6).

First, when the Roman character rule change key 17 shown in FIG. 2 is pressed, the Roman character conversion rule change circuit 44 by the microcomputer 21 shown in FIG. Then, a list and input screen as shown in FIG. 9 is displayed via the display data creation circuit 46.

FIG. 9 shows an example when the rule change table in the change content storage section 45 is in the state shown in FIG.

From the state shown in FIG. 9, the user inputs the Roman character notation and the Kana character string for the combination of Roman characters and Kana characters that he/she wishes to register.

Then, after that input, the Roman character conversion rule change circuit 44
Check its validity (for example, the last notation must always be a vowel, there cannot be more than one vowel, etc.).

As a result of the check, if the combination is valid, the combination is written in the rule change table of the change content storage section 45.

If the combination is not valid, the user is prompted to re-enter the combination they wish to register, and the same process as above is performed.

Figure 11 shows rX in the rule change table shown in Figure 10.
This shows a state in which the combination "a→a" has been added.

The validity rules differ depending on each device, and are not directly related to the gist of this invention, so a description thereof will be omitted. Furthermore, various methods can be considered for the display method and input method shown in FIG. 9, but only examples will be shown here.

In this way, when converting Romaji input using this character processing device to kana, even when using a device that has rules different from the Romaji input rules that you are accustomed to, you can specify changes to the rules that you are familiar with. This eliminates erroneous operations and significantly improves operability.

Furthermore, by registering a pattern of conversion rules that the device in use does not have, the trouble of pressing the shift key can be eliminated and operability can be significantly improved.

Effects As explained above, according to the present invention, in character processing devices such as word processors, it is possible to easily modify the specifications of Romaji-Kana conversion as a means of Japanese input, thereby significantly improving the operability. can.
