Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Japanese human-powered device, and more particularly to a Japanese-based human-powered device in which two types of codes are given to one character, and either code can be input.

Conventionally, in order to input Japanese text including kanji into Word, processors, etc., it was necessary to use the character, symbol keys, shift, and
This is done by operating keys, but either method involves selecting the desired character from a predetermined array and pressing the keys one by one, or a combination of two characters and the shift key. This is a method of inputting information using the following methods.

However, these input methods are side-based (visual input), which causes severe operator fatigue, leads to frequent errors, and also makes it impossible to increase input speed.

Therefore, among the keys that display only katakana, alphabets, and various codes, there is a method of inputting kanji, hiragana, katakana, 'I letter letters, and other characters and codes by encoding them by combining two keys (Japanese Patent Laid-Open No. 49 −
69234 Publication reference field, or a keyboard having approximately 48 keys, with half of each key assigned to each of the four fingers of the left and right hands, with keys corresponding to consonants on the right hand and keys corresponding to vowels on the left hand. By placing , and making two strikes with both hands alternately,
A method has been proposed in which hiragana and katakana are input, and furthermore, kanji and symbols are input by two strokes of a key using a combination of two 50 syllables (see Japanese Patent Publication No. 35453/1983).

These methods are so-called touch methods that allow extremely high-speed touch operations when inputting kanji characters as well as when inputting Western characters by memorizing key combinations. However, in these touch methods, key names are defined by character sequences of two categories, VC and VC, and two names are given to one key, which requires a lot of training time for the operator and requires a lot of training time for the operator. It's not easy to remember. Therefore, prior to the present invention, the applicant of the present application had a key arrangement classified according to character characteristics, and provided a shift function for specifying the key arrangement according to the classification, on a finger-by-finger basis.
The first of the two strokes is the key that gives the shift function,
He proposed an input method in which the other single stroke was a key that represented a character (see the specification for ``Japanese Type Writer's First Keyboard,'' filed on January 29, 1972).

In this method, the shift function that specifies the type of hiragana, katakana, alphanumeric characters, symbols, etc. is performed on the second platform. The middle fingers of the left and right hands are used as the shift keys for the hiragana kiyone for ``2'' and ``yu'', and the ring fingers of the left and right hands [are used as the katakana kiyone shift keys for ``na'' and ``tsu''. ``Mo'' and ``...'' are designated as shift keys for uppercase alphanumeric characters on the pinky finger.

In addition, for voiced sounds and half-voiced sounds, each line that can result in these sounds is placed in the right hand's defense range, so the shift function can be performed with the left hand by pressing "o" as the shift key for the voiced sound and "ru" as the shift key for the semi-voiced sound. specify. In such a method,
Since ergonomic consideration is given to the key arrangement and the keys are arranged without going against the senses of the operator, training time can be shortened.

However, in these conventional Japanese human-powered systems, the code, which is a combination of two key strokes, is fixed for each device, and there is no room for it to be changed by the A-V1 operator.

For example, in a system that specifies a character by pressing two of 48 keys, anything other than 48 x 48 - 2304 (characters) must be input as a non-standard character, which makes processing cumbersome and costly. It becomes hot. Of course, those 2304
Generally, frequently used characters are assigned to the characters, but some users may have other frequently used characters in addition to these 2304 characters.

In particular, characters other than the 2304 characters used in personal names, place names, etc. may be frequently used as characters unique to the user. Even in such a case, in the conventional system, those characters must be input as external characters. That is, after pressing the function key for manual input of external characters, it is necessary to input the four-digit numerical code obtained by referring to the code table by pressing the key. Hey, even if the operator forgets the code or doesn't remember the code from the beginning, he or she still has to refer to the table in the same way as when inputting external characters. Therefore, in conventional Japanese human-powered devices, input of non-standard characters is often required, which requires reference to a code table and five key strokes, which takes time to input non-standard characters, reducing the input efficiency of the V1 Japanese human-powered device. The purpose of the present invention is to eliminate such drawbacks, reduce the number of keystrokes when inputting custom characters, and simplify the operation of inputting custom characters.
An object of the present invention is to provide a Japanese human resource device that can improve input efficiency.

The Japanese human-powered device according to the present invention is a Japanese human-powered device (IC) that inputs characters such as kanji and codes.
A first input code for inputting a character by specifying a frequently used character by a combination of two input keys and storing the combination of the two input keys, and a first input code corresponding to a character code. 1 table and a second table
The code system is characterized in that it has a second table that includes all the character codes in the first table and has a larger capacity than the first table that also includes character codes other than the first table.

Hereinafter, the principle and embodiments of the present invention will be explained with reference to the drawings.

Figure 1 is an explanatory diagram of the main parts of the code system that is referred to when inputting external characters.
Figure 2 shows characters using the code input method. It is an explanatory diagram of a code pair.

In addition to the code input method, when inputting external characters using conventional input devices such as Kanji Telemeve, tablets, or Japanese typewriters, characters such as those shown in Figure 1 can be used. It is normal to use a code correspondence table and enter the numbers written on the edge of the table.

That is, FIG. 1 is based on JIS. This is a simplified diagram of C6226 "Kanji code system for information exchange", which specifies a set of graphic characters and their codes used in normal Japanese sentences.This includes 2965 characters as the first level kanji set, Second
There are 3,384 characters listed as a standard kanji set. On the other hand, the number of characters that can be coded and input by two strokes of 48 keys without using the shift surface is 2304 characters, so if the information processing device is equipped with a printing or display pattern of 2304 characters or more, Other characters can be processed by inputting them as external characters and using numeric codes, etc.

In the code input method, characters and codes are arranged in a correspondence table as shown in FIG. 2, and in the table, frequently used characters are selected and assigned codes.

This code is determined in consideration of ease of remembering, ease of typing, etc. In both Figures 1 and 2, the characters are arranged in on-yomi order, and kanji without on-yomi are arranged in kun-yomi.

However, the code input method shown in Figure 2 does not work! As is clear from a comparison with Figure 1, there are quite a few missing characters in the table. In other words, the missing characters in Figure 2 are
This is a character that is not coded because it is generally used infrequently. FIG. 3 is a modification of the Kanji code system shown in FIG. 1, and is an explanatory diagram of a second character/code correspondence table used in the present invention.

In the present invention, two types of codes are assigned to one character, for example, "love", that is, "raf" for karate in Figure 2, and "aka" for trigram in Figure 3. The code is input with two strokes, but in FIG. 3, after pressing the switch key, the code is input with two strokes.

Well, in Figure 3, "S/A" is a shift. It means pressing the "A" key while holding down the Shift key. By using keys, the variety of codes is doubled. In this way, the characters in Figure 3. Exactly the same number of code correspondences as in FIG. 1 can be secured. If the operator remembers the code, the V1 character ``love'' is input by specifying ``rough'' with the code shown in FIG. 2, for example, two strokes of the key.

Also, when the operator inputs a custom character or forgets the code, first press the function key (switch key) that indicates the second code after referring to the correspondence table shown in Figure 3. Then, by pressing "aka" twice on the key, the character "love" is input. When using the second code, the shift key may be used, but it is possible to input a foreign character with three keystrokes, which reduces the number of keystrokes compared to the conventional five keystrokes.

In addition, when inputting external characters, if the operator forgets the code, it is easier to search if all the characters of the Kanji code system shown in Figure 1 are listed, as shown in Figure 3. . FIG. 4 is a block diagram of the Japanese human power device according to the present invention.

As shown in FIG. 4, the Japanese human power device 8 of the present invention has approximately
Keyboard 1 with 8 keys, code to be operated when inputting second code. Table switching key 2, control unit 3, first code table memory 4, and second code table. Connect memory 5 to common bus 7
Furthermore, the input device 8 is connected to the information processing device 6.

When a code is input by pressing two keys on the keyboard 1, the code is sent to the control unit 3, and the first code. table. Memory 4 is referenced, but code. After pressing the table switching key 2, if you input a code by pressing two keys on the keyboard 1, the code is sent to the control unit 3, and the second
code table. Memory 5 is referenced. In addition, the control unit 3 is a Mytaro. It has a built-in computer, program memory (ROM), and working memory (RAM). Also, the first code. table. The memory 4 is a read-only memory (ROM) that stores the correspondence between codes and character codes shown in FIG. table. The memory 5 is a read-only memory (ROM) that records the correspondence between codes and character codes shown in FIG.

FIG. 5 is a flowchart showing the processing of the control section in FIG. 4.

When the device is activated, at stage 11 the first code. The table 4 is connected, and the stage 12 judges whether or not there is an input of the switching key, and if there is an input, the second code is output.
It is switched and connected to table 5.

Next, the stage 14 waits for a code to be input from the keyboard 1, and if the code is input, the first code. When table 4 is connected, the stage 16 converts the code and outputs the character code to the information processing device 6, (1)
Return to Also, the second code. When table 4 is connected, after converting the code at stage 17 and outputting the character code, the first code. Switch connection to table 4. In the processing of stage 16 or 17, the first or second code. Since correspondence tables between input codes and character codes are stored in tables 4 and 5, the control unit 3 selects the first or second code based on the input code. It searches the table 4, reads out the character code, and sends it to the information processing device 6 via the common bus 7. Figures 6A and 6b show the first code, respectively. table. Memory 4 trigrams and 2nd chord. 5 is a diagram showing the contents of table memory 5. FIG.

The first code in Figure 6a. The second code in Figure 6b than the table. The number of characters stored in the table is larger, and in that case, frequently used characters (character codes) are stored in association with different codes in both tables.

Coincidentally, the character ``a'' shown in Figures 6A and 6b coincidentally corresponds to the same code ``aa'' in both tables. The control unit 3 is a micro. Although the case where code conversion processing is performed using a computer has been shown, the present invention is not limited to this, and may be configured using wired logic.

As explained above, the present invention can replace conventional characters. A first memory storing a code pair, a trigram and a character containing the same character as this memory and specified by a distinct combination. A second memory is provided to record the code markings, and when entering the latter code, the key to switch the memory is operated prior to inputting, so that either code can be entered. The number of keystrokes is reduced, making it easier to input non-standard characters, and the input efficiency of the Japanese human-powered device is improved.
