Abstract

PURPOSE:To easily retrieve a Chinese character key by a simple constitution, and to input a Japanese sentence quickly, by indicating an input key of a Chinese character having a reading shown by ''Kana'' (Japanese syllabary) inputted by a ''Kana'' input key, by means of light emission. CONSTITUTION:An input key is provided on each character of ''Kana'' (Japanese syllabary) and a Chinese character, and on each Chinese character input key, a light emission display means 4 for distinctly indicating its key is provided additionally. Also, this device is provided with a means 2' for switching an operation of a ''Kana'' input key 1 to ''Kana'' input use and Chinese character designating use, and a circuit for converting a signal inputted by the ''Kana'' input key 1 when said switching means 2' has been switched to Chinese character designating use, to a Chinese character signal having reading shown by ''Kana'' which has been inputted. In this way, by an output of this circuit, said light emission display means 4 additionally provided on a corresponding Chinese character input key is operated. For instance, when a circuit as shown in the figure is used and ''AI'' is inputted by turning on the switch 2', keys of ''AI'' (love), ''AI'' (sadness) and ''AI'' (mutual) are illuminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Japanese word processing device used in a Japanese word processor or the like.

In devices that process Japanese information, the step of inputting kanji information is a bottleneck in the efficiency of information processing, and various methods have been proposed for inputting kanji information.

These methods are roughly listed as follows.

(a) Full character arrangement method: This method is used in ordinary Japanese typewriters, and has all the keys corresponding to each kana and each kanji, and the operator selects the keys.

(b) Kanji stroke method There are two-character keys and a shift key. Each character key corresponds to 4 to 15 characters. Press this character key with one hand, and press the shift key with the other hand. A method in which a character within a single character key is selected by pressing it.

(C) Two-stroke method: categorizes kanji into four blocks,
Arrange two sets of alphanumeric characters on the left and right, specify one of the four blocks by pressing the left and right keys (for example, left, left, right, left, etc.), and specify the number within the block by the combination of left and right numbers. A method of specifying one kanji.

(d) Kana-kanji conversion method: A method in which the pronunciation of a kanji is input in kana and converted into A-kanji by the computer's internal processing.All homophones are displayed on the display, and the desired kanji is selected from among them.

(e) Associative input method: One kanji is input by operating the kana key twice, but at that time, in order to avoid specifying homophones and allographs, kana human power is used to express expressions that are different from the reading of the kanji. '', and ``public'' is a method of specifying and using expressions that are easy to remember through association, such as ``ham''.

Of the above-mentioned methods, methods (a) and (b) have been used for a long time and are structurally simple and inexpensive, but require a large number of keys and require skill. (C) is a method similar to (b), but the key operation is performed by looking at a block-divided kanji table, the block to which the desired kanji belongs, and the position within that block, so it requires a large number of keys. It requires the same level of skill as finding the key for the 'object'.

The method (d) is easy to operate and can be used even by beginners, but it has a complicated structure and is expensive. For (e), it is necessary to memorize the standardized kana character expressions in addition to the reading of the kanji, and even though the key operations are easy, using the device requires skill.

From the above overview, it can be seen that no satisfactory kanji input method has yet been proposed. Furthermore, there are two directions in which the kanji information input method can be improved. One of them is to reduce the number of keys, and methods (b) and (C) fall into this category. The other type is input using kana, and (d) and (e) belong to this category. However, the real bottleneck in inputting kanji information is not the large number of keys, but the difficulty in finding the desired key from a large number of keys. )
The level of skill required for method (a) is the same as method (a), and it is necessary to memorize the key or position of the target kanji in the table.

Therefore, as long as there is a way to know at a glance where the desired kanji is, it is possible to have many keys, and it is not necessary to have a complicated structure in which all the kanji with the same or different characters that have been manually created using kana are displayed on the display. .

The present invention is an improvement of the kanji information input method based on the above-mentioned viewpoint, and is structurally as simple as the above-mentioned method (a), and operationally functionally similar to the above-mentioned method (e). The aim is to provide a comparable device.

The device of the present invention is equipped with keys for all characters of kana and kanji, and when the reading of a kanji is input using the kana key, the key of the kanji with that reading will be displayed with a light emitting light. It is a Japanese writing machine that allows you to select and press a kanji. The present invention will be explained below with reference to Examples.

FIG. 1 shows a keyboard in one embodiment of the invention.

The keyboard has 5 keys, 2 keys for Kana characters, 2 keys for Kanji characters, 1 key for Romaji characters, etc., and the arrangement is the same as the type heading board of a Japanese typewriter. In addition to character keys 1, the keyboard has a search key 2. The search key is part of the means for switching the operation of the kana person key between kana manual operation and kanji specification. Normally, by pressing the above-mentioned character input key 1, information on the character displayed by the pressed key is input into the Japanese text processing device. This operation is the same as that of an ordinary Japanese typewriter. If you cannot immediately find the entry key for the desired kanji, press and hold the key 2 and enter the reading of the desired Kanroku (on or kun) on the hiragana entry key. . Then, the input of kana is prohibited and the kanji entry keys for some kanji with that reading are illuminated by the lighting device and appear to glow, making it extremely easy to find the entry key for the desired kanji among them, and search. When the user releases key 2 and presses the found kanji input key, information on the desired kanji is input into the device.

FIG. 2 shows the structure of the kanji input keys in the keyboard shown in FIG. Reference numeral 3 denotes a key top made of a translucent material, with Chinese characters to be input written on the top surface, and a light emitting element 4 arranged on the bottom surface of the key top 3. Below the key top 3 is a switch 5 and a member 6 that transmits to the switch 5 that the key top has been pressed down.

Other kana person keys, Romaji keys, etc. have the same structure, but the light emitting element 4 is not attached.

FIG. 3 is a circuit diagram of an apparatus according to an embodiment of the present invention.

1 is a kana person key, and although only the five Ai-ueo keys are shown in the diagram, in reality, all the hiragana ' keys are lined up.

Below these keys is the switch 51 shown in Figure 2 (there is another Kanajin Kaki-5, although it is not shown in the circuit diagram), and one terminal of these switches is connected to the common line 7. The common line 7 is grounded via a switch 2' operated by the search key 2 when the search key 2 is pressed. The other terminal of each switch 5' is connected to converter CON.

Converter CON converts kana characters into 8-bit data using a diode matrix as shown in the figure.

The input keys for kana characters are the 50 sounds of Aiueo and the voiced sounds.

10 including semi-voiced sounds and persistent keys such as kiya, shu, and shiyo.
There are about 0 pieces. Converter CON horizontal line A.

A voltage V is applied to the ports 1 and 2 through a resistor R, and the voltage V is normally at a high level. Now, for example, if you press the "A" key, the horizontal line A will pass through the diode and the line will be diced, switch 2
' is connected to ground and the horizontal line A becomes Low level. This, of course, applies when the search key 2 is pressed, that is, when searching for a key containing kanji characters, and the following explanation will be based on this case. The vertical lines @a, b, c, . . . connected to the ends of each horizontal line of the converter CON are connected to two sets of latch circuits Ll, L2 via an inverter. When you press the "A" key, converter CON
Only the horizontal line A is LOW, but if this state is regarded as a binary code and the output of the converter CON is 011...1, the output of the inverter E is 100...0. Each horizontal line of the conometer COH is connected to the input terminal of the AND circuit A. Normally, all bits of the output of CON are 1, and the output of the AND circuit A is High. When one of the kana keys 1 is pressed, the AND condition of the input to the AND circuit A is canceled, and the output of A falls to Low, and this fall triggers the monomulti circuit M1. The FF is an RS flip-flop that is normally in a reset state and is triggered by the output pulse of the monomulti circuit M1. Therefore, the FF is set when the first kana key is pressed, and returns to the reset state when the second kana key is pressed. The monomulti circuit M2 is triggered by the rise of the set output Q of the FF, and the latch circuit L1 latches the output of the inverter according to its output. When the second kana key is pressed, the mono multi-circuit M3 is similarly triggered at the rising edge of the FF reset output, and the M
3, the latch circuit L2 latches the output of the inverter at that time.

With the above-described configuration, the sign of the first sound of the reading of a kanji is latched in the latch circuit Ll, and the sign of the second sound is latched in the latch circuit L2. In this embodiment, the pronunciation of a kanji is expressed by one or two kana characters (one character is tsuon), and the pronunciation can be either ontome or kun. I will discuss how to handle the readings of kanji later.

t, m, -; r, s and /1. m',
-! The output of the latch circuit L1 is applied to the first pass line 1-fJ, and the output of the latch circuit L1 is applied to the first pass line 1-fJ, and the second pass line! 1 to s1 (L2<7) output is applied. Both pass lines are connected to converters C1, C2, .

The converter C1 etc. consists of one AND circuit, several inverters, and a NOR circuit. In the case of a kanji character expressed as a kana character, the output of the latch circuit L2 is all bits 0, so in the corresponding converter, the second pass line z
All bit outputs of l-B l are applied to the AND circuit through a NOR circuit. In the figure, the converter for the kanji with the reading ``a'' is exemplified as 01. As mentioned above, the output of the inverter for the kana "A" is held at 100...0 in the latch circuit L1, and the L*'o) output is all bits 0. Converter C1 outputs j of pass line /-6 and m, n...
The output obtained by inverting the output of S and the second pass line z l-s
The NOR signal of the output of I is applied, and when the character "A" is pressed, a High signal is output. This output is sent via the amplifier AMP to the light-emitting display element 4 attached to the printed kanji characters "A" and "A" to illuminate the kanji keys for "A" and "A". Therefore, when inputting the kanji ``A'', the user should let go of the search key 2 and press the ``A'' key. When the search key 2 is released, the switch 21 is opened and the latch circuit and flip-flop FF are all reset.

Further, the explanation will be continued using an example of searching for a key to input the kanji ``love''. In this case, press the search key 2, first press the "A" key, then press the "I" key. Therefore, the latch circuit Ll.

L2 each holds data, and the output of Ll is '100...
As can be seen from the figure, the output of L2 is 010...0. In this case, the output of converter C1 is Lo because the NOR circuit output becomes O and the AND condition of the AND circuit is not satisfied.
It becomes w. Generally, when the kana key is pressed twice, the kanji key display that was displayed when the kana key was pressed the first time disappears. Converter C7 is configured to convert the kana character ``Ai'' into the corresponding kanji, and its output is output from amplifier A.
Via the MP, it is sent to the light-emitting display element 4 attached to the kanji keys for "ai", "gou", "sai", and "ao", and the words "ai", "gou"
The kanji keys for "Ai" and "Ai" are illuminated. Since you can immediately see where the key called ``Love'' is, let go of the search key and press the ``Love'' key.

If the search key 2 is not pressed, the switch 2' is open and the circuit shown in FIG. 3 is not activated, and if the kana key is pressed, the kana data is input.

As you can see from the above explanation, you can read kanji either by its sound or by its kun. This is a problem in how the converters C1 to Cn are assembled. The kanji ``Ai'' on the top side is also ``Ai''.
You can also search for ``so'' or ``try''.

In most cases, two syllables (two kana characters) are sufficient for the reading of kanji, but in the case of kun, three kana characters may be required.

For example, ``shine'' is ``kagaya'' ki. In the above example, “
``Kira'' is processed with ``ki'' or ``kaso''.

In the above embodiment, the flip-flop FF is a ternary counter, and its counting output is 1. 2. One shot M2. M3. Install 3 M4 (7) Latch circuit Ll
, L2. L3. If you prepare three pass lines, you can handle the reading of kanji up to three kana characters. In this case, the sound key is not needed. For example, in the embodiment shown in Figure 3, "shaku" is "
``ja'' and ``<'' are treated as two characters, but this is one character.''
It will be treated as the three characters ``yacho'' (ku).

With the above-described configuration, the device of the present invention can display a group of kanji keys with the desired pronunciation by operating the kana key in conjunction with the search key, so only one kanji of interest can be displayed. Although it does not do much, searching for kanji keys is actually much easier, and Japanese text can be entered quickly.

In the past, efforts were made to reduce the number of keys (such as (b) and (C) mentioned above) or to process only kana keys, but the reason for the inefficiency of Japanese human power was to begin with. This is not because there are a large number of keys, but because it takes time to search for the required key, and if this point is solved, a great improvement in efficiency can be obtained. The present invention has been made from this point of view, and has the advantage that the circuit configuration is much simpler than the system using a computer, and it does not require any association or other skills. (b) It can also be applied to the Kanji stroke method. In this method, one kanji key corresponds to several kanji, and another shift key is used to specify which kanji within one kanji key.By using both hands, the number of keys is reduced and efficiency is improved. It is something that

When the present invention is applied to the kanji stroke method, one key corresponds to multiple kanji characters, but as a light-emitting display means, one lamp per key is enough to confirm the kanji position. .

FIG. 4 shows an example of this, in which all kanji are divided into four groups, and one character from each group, a total of four characters, is made to correspond to one key. For example, when inputting ``love'', use the shift key (not shown) to select the first group and press the key (1o), and when inputting ``kai'', select the second group and press the key (1o). .

In this kanji stroke method, each key has a lamp (12
-li (12-2) (12-3)... are provided, and if you search in the same way as in the above example, the lamp (12-I) will be lit.
You can know the key position corresponding to the 14fl kanji for ``Ai・Gei'' and the group to which the user belongs based on the position of the kanji on the key top (for example, ``Ai'' is in the upper right).
