Abstract

PURPOSE:To improve both the operability and the input speed and to realize a compact structure for a Japanese word input device by using the keys arrayed in two rows of five pieces each to store the input key signals and converting these signal into codes every two pieces. CONSTITUTION:A memory 5 stores the input value every time a key signal is inputted from a keyboard 3 and sends successively the keying input values to a conversion means 6. If the received keying input values are equal to the key codes obtained by keying the numeric keys, the means 6 converts the keying values into KANA (Japanese syllabary) codes every two pieces by reference to a conversion table 7 and sends these KANA codes to a word processor processing part 8 of a word processor main body. The part 8 carries out various processes based on the input KANA codes and other input codes and at the same time displays the input contents at a display part 2. While no conversion of codes is carried out and the keying input values are outputted as they are in case the function keys except the numeric keys are pushed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a Japanese language input device used in Japanese language processing equipment, and in particular, to portable word processors, Vogecon, electronic notebooks,
This is a Japanese language processing device suitable for compact Japanese language processing devices such as electronic dictionaries and handheld terminals.

[Prior art and its problems]

In recent years, Japanese language processing devices such as word processors have become smaller, and various devices suitable for carrying are now on the market. The input device of these Japanese language processing devices uses a keyboard for -C, but this keyboard is a bottleneck when trying to downsize the Japanese language processing device. In other words, a human-powered keyboard for kana requires approximately 50 keys for the kana characters, so there is a limit to miniaturization. , you may accidentally press the next key as well.

In addition, in the case of Romaji input, although the number of keys can be reduced by almost half compared to kana manual input, there is a drawback that the number of keys is changed twice, and operability is sacrificed.

Therefore, this invention takes the above points into consideration, and is easy to downsize.
Moreover, the arrangement and definition of the keys are reasonable and easy to use.

f stage for solving problem c] The Japanese input device of this invention has five stages arranged in two rows.
Five row names and five types of vowels out of the 10 row names that almost make up the Japanese syllabary are assigned to one key column of the 0 key group, and the other key column is assigned the same key column as the other key column. A keyboard configured by overlappingly assigning 5 types of vowels and the remaining 5 line names in the same order, and the keystroke signals output from this keyboard sequentially? A conversion table that assumes that the manual keying force value input continuously from the keyboard is specified by alternating line names and vowels, and writes the kana needs corresponding to each of these combinations, and the memory. The present invention is characterized by comprising means for reading the human power values consecutively stored in units of two and converting them into kana codes by referring to a conversion table.

[For production]

In this invention, 10 key groups are arranged in 2 columns of 5 keys each, and in both columns of the key group, line names and vowel names that almost make up the 50 sounds are defined redundantly, and 4) vowel are arranged in common in both columns, and keystroke signals obtained by alternately pressing these 10 keys to specify row names and vowel names are sequentially stored in the memory.

Next, the keystroke force values stored in the memory are
It is read out in units of pieces and converted to kana code by referring to the built-in conversion table.

〔Effect of the invention〕

This invention uses five keys arranged in two rows to perform kana manual input using the Romaji system with two strokes of the touch, which improves operability and significantly improves the speed of manual input compared to the conventional Romaji system. can.

At the same time, the layout of the keys is easy to memorize and is logical, so you can quickly learn how to operate the keys and learn blind touching in a short time.

Furthermore, since fewer keys are used, the keyboard can be made smaller, and Japanese language processing equipment can be made smaller accordingly.

[Example〕 Embodiments of the present invention will be described below based on the drawings.

1 to 5 show an embodiment in which the present invention is applied to a portable word processor, and FIG. 1 is an external view thereof.

As shown in FIG. 1, a display section 2 and a keyboard 3 are arranged on the surface of the word processor main body 1.

The keyboard 3 is structured in three stages, with numerical keys 1 to 5 arranged in the upper stage and numbers 6 to O in the middle stage. Function keys F1 to F5 are arranged in the lower row.

These keys can be operated, for example, with the index finger of the right hand or with a plurality of fingers.

The upper and middle number keys have the vowels A, I, TS, WORK, O, and the line names in 50RF, A, 力, SU, DU, SU, H, MA, as shown below. , Ya.

U and W are each assigned duplicately.

In addition, each vowel is commonly assigned to the middle numeric key of "-7," which not only makes it easy to memorize the vowel keys, but also allows for rational fingering when touching the keys.

Function keys F1 to F5 define shift I, kanji conversion, and other various control operations.

In addition, in the illustrated example, the assignment of vowels and line names is simply 50.
Although we have used the order of the sound chart, considering the frequency of use of each kana, we can further improve operability by placing the relatively frequent vowels i, o, a, as well as gyoumeiriki, yu, na, etc. on the left side. do.

Furthermore, although the number keys on the keyboard 3'' are arranged in two horizontal rows, they can also be arranged in two vertical rows.

FIG. 2 is a block diagram showing the construction of a word processor.

In the figure, a human keystroke signal from the keyboard (-3) is input to a conversion unit 4.The conversion unit 4 is constituted by a microprocessor, and is stored in a memory (not shown). This conversion process will be explained with reference to a block diagram schematically shown inside the conversion unit 4.

First, the memory 5 stores input values each time a keystroke signal is manually input from the keyboard 3, and further sends the stored keystroke input values to the converting means 6 one after another.

If the sent keystroke input value is a keycode obtained by pressing a numeric key, the conversion means 6 refers to the conversion table 7 in units of two and converts it into a Gana code, and processes it in the word processor itself. Send to section 8.

This conversion table 7 is written in a storage means such as a ROM (not shown).

Note that the processing section 8 executes various processes based on the manually input kana code and other manual codes, and at the same time displays the input contents on the display section 2.

Although the converting section 4 and the processing section 8 are shown as having separate configurations in the figure, the processing operation of the converting section 4 can also be performed as one of the operations within the processing section 8.

FIG. 3 is a diagram showing the contents of the conversion table 7.

As shown in the figure, when 10 keys are pressed twice, there are 100 combinations, including not only normal kana, but also lowercase letters, voiced sounds, ゛1', voiced sounds, punctuation marks, and parentheses. Can be done. In addition, in the blank space in the table,
It is also possible to allocate control operations that are particularly frequently used.

In the figure, the key pressed first serves as an input for specifying a line name in the Japanese syllabary, and the key pressed later serves as an input for specifying a vowel.

This conversion table is constructed based on the 50-syllabary table,
For Kiyone, which is particularly frequently used, line names and vowels are specified by pressing the keys alternately on the left and right, while for voiced sounds and lowercase letters, they are distinguished by pressing the keys with the fingers of the same side. In addition, “n” that does not protrude from the 50-syllabary table, 11’-voiced sounds, and consonant “n”
, long notation "-", punctuation marks, parentheses, etc. are also assigned to each empty column.

Using this conversion table, for example, if you try to enter the word ``Harappi na Bocchan 1'', 6-1-5-3
-7-70-7- [Kana conversion] 5-6 [No conversion] -6-
It can be done manually by operating the keys in the order of 0-5-3-4-7-8-6-0-3 [Kanji conversion].

Further, although numbers and alphabets are not listed in this conversion table, when entering numbers, shift conversion is performed using the function keys, and the number keys can be input directly without conversion.

In addition, for English characters, you can either match kana to the English characters in advance and convert them one character at a time and convert them to English characters, or you can shift convert them to alphabetic characters and input them continuously in the same way as when inputting kana characters. It can also be done manually.

In addition, when inputting a frequently used clear tone, the keystrokes are the upper and lower rows of the upper and lower rows.

Further, in the illustrated example, the row name is specified first, followed by the vowel name, but it is also possible to specify the vowel name first in the reverse order.

FIG. 4 shows another example of the conversion table. This conversion table makes it easier to input numbers manually, and when you press a number key twice, the key number is input manually. For this reason, voiced sounds, ゛1-voiced sounds, and lowercase letters are converted by inputting the conversion code shown in the table before or after inputting J, (Kiyotaka, which is a wooden kana).

FIG. 5 is a flowchart showing the operation of this embodiment.

As shown in the figure, when the numeric keys are pressed,
The contents of the keystrokes are stored in the memory, and at the same time, by referring to the conversion table, the keystroke input values are converted into kana codes in units of two and sent to the processing section 8 of the word processor.

If a function key other than a numeric key is pressed, it is output as is without being converted.

Although not shown, the input value for the first stroke may be displayed on the display section 2 by a white key number, etc., and the input value for the second stroke may be displayed in reverse on the manual input value such as Kana. You can also do it.

Furthermore, if the user accidentally presses one key during input, the subsequent vowel designation and line name designation are swapped, resulting in meaningless manual effort. Therefore, it is equipped with a correction function that shifts the combination of vowels and line names in the part that was entered by mistake, reconverts it to the correct kana, and redisplays it.

FIG. 6 is an external view showing an embodiment in which the present invention is applied to a wristwatch-type electronic memo.

In the figure, the electronic memo 9 is formed in the shape of a wristwatch with a pan 94, and is equipped with a display section 92 and a keyboard 93 on the surface of the main body.

The display section 92 displays human-powered characters during manual operation and displays internally stored sentences and data. Also, when you are not using the electronic t-memo, it displays the date and time as a clock.

The keyboard 93 has numeric keys for human input in Kana and Kana on the G and middle rows, and function keys for changing the hour a1 display and defining other control operations on the F row. Further, although not shown, in addition to displaying numbers, line names and vowel names are displayed on the numeric keys.

The basic configuration of the manual device inside the electronic memo 9 is the same as that of the first embodiment shown in FIG.

Konomi/-J Mo9 km, 2F-Ho 1'93
Because it is composed of 13 keys without any keys, Kana 50f
It can be made into a small wristwatch type while still having the human power function of 1. Furthermore, the function key can be changed to keyboard 9.
Completely removed from 3-F, side ribs, -z-shaped button 94
Alternatively, it can be made more compact by defining an empty field in a two-stroke conversion table as a function key in the same way as for kana input.

Further, sentences, data, etc. input into this electronic memo can be output by connecting to other Japanese language processing equipment such as a word processor or a personal computer through a connector 95 provided on the side of the main body.

Similarly, data created elsewhere can also be stored in the electronic memo via the connector 95.

As is clear from Examples 1-1 below, the human-powered device of the present invention has excellent human-operability despite its small size. Therefore, by using these devices in various Japanese language processing devices, especially portable Wablo, Bokekon, electronic notebooks, electronic dictionaries, and handheld terminals, which are characterized by their small size, we are trying to make these devices more advanced. It can be made into a performance product.
