Abstract

A multilingual character input/output device provided with eight for specifying basic strokes of characters and four for controlling character generation, to type Roman alphabets, kana characters of Japanese, Cyrillic alphabets of Russian, and Arabic numerals. A method of inputting characters by using twelve keys such as push buttons of telephone sets has been known in the past, but such a method uses combinations of numerals or special keys several times as a character generation device. Such a method is likely to invite an input error and requires a user to remember essentially the specific combination sequence without error. The system of the present invention uses only the keys for basic strokes expressed by (I), and can input/output Roman alphabets, Arabic numerals, kana characters and Cyrillic alphabets. Therefore, the input/output device can be combined with a super-smart card, a portable information transmission device, a telephone set, etc., to provide a compact interactive data transmission system of high performance.

Description

Description Title of invention

Multi-language character input / output device

Technical field

The present invention relates to a technical field relating to a device capable of inputting and outputting multi-national characters and text in a communication device, a computer and other 'hobby processing devices. Technology background

Conventionally, as a character input device for information and communication equipment, there are a view key board method having 103 keys and a method of inputting characters (Roman characters) with 12 keys as in a key telephone. Fig. 2 shows a device for inputting and outputting Roman characters on a key telephone, and Fig. 3 shows a method of a device for inputting and outputting Roman characters using combinations of numbers. If you try to enter the Roman character Α using the device shown in Fig. 2, convert it to the character input mode and press the number 2 on one side to display it on the display.

Β The character can be input / output by pressing 2 twice, C character 3 times, and D character 3 once. Also, input and output Roman characters with a device as shown in Fig. 3. For example, A can be output by pressing the numbers 1 and 4 頫, and B by pressing the numbers 4 and 1. The method of inputting characters using such a system is difficult for the party and easy to make mistakes, and requires considerable learning time. Also, if you try to input and output multi-national characters other than Roman characters using a conventional device, the system will be the same as the Roman system, so the inconvenience of the same method will be unavoidable. Detailed explanation of the invention

In character input devices such as communication and information processing equipment, the required input device method and mechanism differ depending on the character system. A typical character input device is a preview keyboard, but it is designed to be able to input based on a character arrangement of each country based on a common hardware key. Although it still has a mechanism that allows characters such as alphabets to be entered on the 12 key, such as a telephone key button, the method and device using the 12 key for other characters are not yet seen. Not hit. The present invention is a device that can input Roman letters, Kana characters, numbers, and Kirill characters by applying keystroke of characters constituting characters of each country to the eight keys based on the 12 keys.

[Division that the invention is trying to solve]

Device B of the present invention solves the limitations of the conventional multilingual character input / output system as described above. The purpose of the present invention is to provide a device S having a system capable of inputting and outputting Japanese characters.

[Means for solving Section S]

FIG. 1 shows a basic device of the present invention. In other words, character symbols are arranged on 8 of the 12 keys, and control symbols are arranged on the remaining 4 keys. These eight characters are extracted from the basic strokes (strokes) that make up the characters from the composition of 26 uppercase Roman letters, 10 uppercase letters, 10 kana numbers, 50 kana characters, and 30 uppercase Cyrillic letters. The four control symbols are used to switch the input / output mode of each character and to control the cancellation, correction or display of the input cast.

As described in the background of the related art, the method of inputting multi-national characters with the 12 key and the device B have not been technically established yet, and remain as difficult problems. The present invention is intended to solve such a problem. Multilingual characters can be input by simply writing each character and inputting a decimal number with a simple device. It will be possible to provide various service technologies for information and communication equipment.

[Action]

In Fig. 1, →, Z,, ·, 0, C, eight strokes are used for inputting Roman characters (English, German, French). Figure 4 shows each It is a table of stroke composition rules for inputting and outputting Roman characters. Fig. 5 shows the composition rule table for digit strokes for inputting and outputting Arabic numerals. Fig. 6 shows the composition rule table for Kana characters. Fig. 7 shows the composition rule table for Russian Cyrillic characters.

At the time of character input in each country, the input character mode is set to S by using the selection key defined as the character control mode. Then, by inputting the stroke of the selected character, the required character is generated by the newly used composition rule.

FIG. 8 is a table showing a method for expressing the basic stroke 8 捆 described above in a computer, that is, a table showing image code information. In general, the character 'hoho' is expressed in units of 7 or 8 bits. For example, US alphabet characters have ASCI I codes, and each country has a specific character code specified for each country. In the device of the present invention, 12 basic strokes and 4 strokes and 4 characters for character display control are used, and a total of 12 are represented by 4 bits. Each stroke is represented by 4 bits, and each character is represented by 7 or 8 bits. That is, the letter Alphat A

(00 1 1) + (0 100) + → (0000)

=> 100000 1

The character code specified by the standard code (AS C I I) of each character system is generated.

[The invention's effect]

As described in detail above, if the multinational character generation method according to the present invention is used, the same hardware Multi-national characters can be input and output under the interface of software, so not only the versatility of information and communication equipment can be reduced, but also the size and application can be improved.

For example, a paiser with a two-way communication function can have a character input / output function, and the application of message communication can be enhanced. Also, Super Smart Card

(super siart card) If this device is used, not only will it be possible to mount a card used in multiple countries, but it will also be possible to add various high performances. ¾ If this method is used with the talk button key, the application field of the current telephone is expanded, and the computer can be accessed by telephone, so that the telephone can be applied as a data access device such as an automatic telephone number guidance system.

Next, an embodiment of the device E of the present invention capable of generating multinational characters with an input device having eight basic sleeps (strokes) will be described.

First, use the mode key in Fig. 1 to select the mode of the character to be entered. In other words, the current character input mode appears on the display, but if you press a numeric input mode, alphabetic character, kana character, or Kiriel character, the desired input character mode will be changed. Can be. Switching between the input mode and the mode for editing the input characters can be distinguished by switching. For example, if you want to input the number 9 after selecting the number input mode S, press 0 and Φ or O to get '9' according to the following internal state change according to the composition rule defined in Fig. 5. The numbers are combined.

0 * / 9

(S 1) (S 2) (S 3) → (S 1)

* Is used for the character era. Of course, internally, a binary 1 0 0 1 1 1 0 of the ASCII code 9 is generated by a combination of the internal code 0 0 0 1 of O 0 0 1 and 4 and the delimiter code 1 00 0. With the same input method and internal operation function, numbers from 0 to 9 can be input and generated.

Also, press' \ '' →, '*' in alphabetical character input mode. If the letter A is generated <

\ → * / A

(A1)-→ (A2) —— → (A3) —— → (A 4) (A1)

In the above figure, if you enter · in the initial state of A 1, then move to A 2, if you enter \ in A 2, the state will move to A 3, and if you enter in A 3, the state of A 4 will go to the exhaustion of A 4, If a * is inserted in the state, the character 'A' is output and the state is displayed in A1. Alphabets A to Z can be generated by the same internal operation function. In addition, ゥ mlautgak Roman letters, such as A, can be generated with A, · · and *.

For Kana characters, if you select Kana character mode and want to input the character 'ゥ', for example, enter ·,-, · and * Input can be generated. Also, if you input Japanese phonetic characters by Kana character input or alphabetic character input first and then use the conversion system, you can expand and expand the system to input and output Kanji characters. is there. .

· * / ゥ

(K1) ichi-→ (K2) (Κ3) —— → (Κ4)-→ (Κ1)

In the case of Kiril, which is a Russian alphabet character, a predetermined character is generated by inputting a stroke in accordance with the composition rules shown in FIG. For example, the Kirill statement Character 3 is synthesized in the same way using the basic stroke.

*

(R 1) (R 2) → (R 3) → (R 1)

According to the configuration of the present example, multi-national characters such as alphabets of Roman characters, Arabic numerals, Kirill characters, and Kana characters can be input using the designation keys of the eight basic strokes that compose each character. Compositing rules can be defined for all characters, and it is still possible to implement concrete rights. In addition, the rules defined by the multinational character composition rules are regular rules (regular granner) in computer computational ife, so it is possible to implement hardware for multinational character input devices using simple electronic circuits (finite state nachine). When inputting each character in the present invention, * used as a character generation mark is also used as a shadow information input as a boundary point between a character to be input before and a character to be input later. If the input time of the last stroke key of a certain character is adjusted to a time length that can be distinguished from other keys, the input timing will be different, and each character can be distinguished. Can be realized without inputting Also, since the codes of multinational character basic strokes represented by 4 bits are standardized in each country, the mechanism for generating character codes can be obtained by simply using simple countermeasures. A machine that calculates combinations is easily realized. Industrial applications

The present invention relates to a device B capable of inputting and outputting multinational characters and text in information processing devices such as communication devices and computers. That is, the device of the present invention can input and output Roman characters, Kana characters, Arabic numerals, and Kirill characters with only 12 keys.

Recently, information processing equipment and communication equipment have become smaller, more sophisticated, and more sophisticated. Accordingly, the economical and technical value of such equipment is that the physical structure of the equipment is simple, portable, easy to learn, natural, and applicable due to expanded functions. Is evaluated according to criteria such as good ones.

In particular, the demand for software technology that can provide a variety of service functions on the hardware of equipment is increasing in the internationalization of information communication and the localization of information content, as in today.

In such an environment, the device of the present invention can be used as a simple multilingual character input / output function device in information and communication equipment, for example, a multinational character input / output telephone, a super smart card, a two-way paiser, a computer, and a terminal. it can.
