Description

DETAILED DESCRIPTION OF THE INVENTION [Field] The present invention relates to a character processing device that converts hiragana input in kana or romaji into other character types.

(Prior art) Conventionally, electronic dictionaries that convert Japanese input in kana into kanji-kana-mixed words correspond to kanji-kana-mixed words, such as ``beautiful'' for ``utsukushi''. Japanese words were stored in the form of general Japanese dictionary headings. However, this has the disadvantage that when converting Japanese words such as "Camera Exhibition" that are mixed with katakana and hiragana, you have to input the character types separately, and the operability during input deteriorates each time the character type changes. was there.

〔the purpose〕

The invention of the tree eliminates the above-mentioned problems, and allows for example "Hiragana headings", "Katakana headings", etc. in electronic dictionary files.
The purpose is to provide an electronic dictionary file that stores 4 headings: ``Kanji headings'' and ``English headings'', allows searching for the other 3 headings from ``Hiragana headings'', and improves operability when inputting text.

〔explanation〕

An example of the operation according to the embodiment of the tree invention will be shown below. For example, when outputting the Japanese word ``camera exhibition'', the input wheel ``kamera/ten'' is given.

The slash between "kamera" and "ten" means the boundary between words. At this time, when you press the search key in Figure 2, "Camera" is replaced with "camera", when you press the conversion key, it changes to "ten", and when you also press the search key, it is replaced with "ten". If you press the search key further, you will see ``Exhibition'', point r''.

Groups of homonyms of ``ten'' in ``shop'' are displayed one by one. In this case, by pressing the conversion key shown in FIG. 2 when "Ten" is displayed, "Ten" is replaced with "Ten".

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment according to the present invention. Here, the CPU is a central processing unit that is in charge of various calculations and control of peripheral devices. The ROM is a program memory that stores execution programs for the central processing unit CPU as shown in FIGS. 3, 4, 6, and 9. B
L is a pass line that connects other memories, peripheral devices, etc. and transmits signals. KB is a keyboard, which performs an input function. RAM is a random access memory that includes document memory ME, homophone buffer BU, and homophone counter CO.
1 document end address EAD, cursor address CAD
, and an insertion flag IF. The document memory ME stores characters input from the keyboard KB, converted Kanji characters, and the like. .

The homophone buffer BU stores readings and kanji corresponding to the readings. Homophone counter CO is homophone buffer BU
Specify the display order of homophones stored in . The document end address EAD stores the last address where a character exists in the document memory ME. cursor address CAD
remembers the cursor position. The insertion flag IF serves as a switch for determining whether or not to perform insertion processing.

The LCD is a liquid crystal display that displays character strings input from the keyboard KB, contents of the document memory ME, and other information such as a cursor.

The DCT is a display controller that controls a liquid crystal display (LCD).

CG is a character generator that stores fonts corresponding to character codes.

DTC is an electronic dictionary file that corresponds to hiragana.
"Katakana", "Kanji", and "English" are memorized.

FIG. 2 is an overview diagram showing details of the keyboard KB of FIG. 1. Among these, the kana and symbol key group is equipped with a plurality of hiragana, katakana, and character/symbol keys such as "," and ".". The cursor left movement and cursor right movement keys are keys for moving the cursor left and right. LIL has the function of adding an upper line to the characters displayed on the cursor display using the upper line key. The SC has functions such as comparing a kana character string with a dictionary reading, creating a homophone buffer, and confirming the selection of a homophone using a search key. TR is a conversion key and has a function of sequentially displaying kanji in the homophone buffer.

With the above configuration, the operation of the embodiment of the present invention will be explained with reference to flowcharts.

As soon as the power is turned on, the wood device proceeds to step St in FIG. 3. In step S1, random access memory RAM
Clear the document memory ME, homophone buffer BU, and homophone counter Co in the same circle, and set the same circle document end address EAD to 0.
Initialization processing is performed such as setting the cursor address CAD, setting the cursor address CAD, and turning off the insertion flag IF. After that, the process proceeds to step S2, and the keyboard KB shown in FIG.
Waits for key input from . Therefore, if any key is input, the process proceeds to step S3, where the input key is determined, and the process proceeds to any one of steps 34 to 10. Step S4 performs processing when a character/symbol key is operated.

A detailed flowchart of the above-mentioned character input processing step S4 is shown in FIG. First, an upper line bit is added to the input character code in step S4.1.

Here, the difference in internal code between normal display characters and characters with an upper line will be explained.

Generally, the document memory of a character processing device consists of one word, or 16 bits, for each character. The code of each character is assigned to each bit in a one-to-one correspondence starting from 15 bits, and the most significant bit, ie, bit 0, serves as the upper line bit UB. For example, as shown in Figure 5(a), the code for "A" is r2422J in hexadecimal notation, but the code for "A" with an upper line is rA422J as shown in Figure 5(b). It has become.

Now, in step S4.2, it is determined whether the insertion flag IF in the random access memory RAM is in the ON state or in the OFF state. If it is OFF, step S4.
4, if it is ON, proceed to step S4.3.

When the insertion flag is ON, in step S4.3,
In the document memory ME, the cursor address CAD shifts the character array after the address indicated backward one character at a time.

Next, in step S4.4, the cursor address CA
The input character code is stored at the address indicated by D in the document memory ME. Thereafter, in steps S4 and 5, 1 is added to the cursor address CAD, and the character input process S4 in the flowchart of FIG. 3 is ended.

Next, the dictionary search in search process S5 in FIG. 3 will be explained.

When the search key SC is pressed, the katakana heading, kanji heading,
Store all English headings in the homophone buffer BU.

Using the example of FIG. 6, which shows the process of creating the word "camera exhibition," the search key SC is operated from FIG. 6(a) to FIG. 6(b) and FIG. This is a step from (d) to FIG. 6(e). Incidentally, the state of the homophone buffer BU will be explained with reference to FIG. The area for one word consists of nine words.

Hiragana headings are stored first, then katakana headings, kanji headings third, English headings last, and the check code CCD is stored at the end.

Next, the procedure of the conversion process S6 in FIG. 3 will be explained with reference to FIG. First, in step S6.1, the homophone counter C
Add 1 to O. This is to indicate the next homophone area of the currently displayed homophone. Subsequently, in step S6.2, the character code in the new homophone area is checked. If the code is CCD, the process proceeds to step S6.3, where the homophone counter is set in preparation for redisplaying the homophone buffer BU from the beginning. Set Co to 1.

On the other hand, if the check code is other than CCD in step S6.2, the process proceeds to step S6.4, and the character code in the area corresponding to the homophone counter CO is stored in the document memory ME. At this time, the document memory ME is filled up when the number of characters is small so that there is no space left in the document memory ME. Taking Figure S6 as an example, the conversion key is operated during the process of transitioning from Figure S6 (b) to Figure 6 (C) and from Figure 6 (e) to Figure 6 (f). The structure of this electronic dictionary file is as shown in FIG.

&LTm71. +-h-\ノII/f:i? ,i'+I
+#-Vl+h-)/I Rev; Performs processing when a movement key is operated. That is, in the case of a cursor left movement key, 1 is subtracted from the cursor address on the random access memory RAM, and in the case of a cursor right movement key, 1 is added. After such processing, a cursor is displayed on the liquid crystal display LCD.

Step S8 for performing upper line processing is a process when the upper line key UL is operated, and sets 1 to bit O of the character code stored at the address on the document memory ME indicated by the cursor address CAD, that is, the upper line bit. It is set to the state before the selection is confirmed, and the cursor address CAD is incremented by 1 and the cursor is displayed.

Step S9 is a process when the insert key is pressed, and turns on the insert flag IF in the random access memory RAM.
When it is OFF, turn it OFF, and when it is OFF, turn it ON.

Step S10 is a process when the delete key SK is pressed, in which one character at the address on the document memory ME indicated by the cursor address CAD is deleted, and the character code after that character is filled in one address at a time.

In addition, the electronic dictionary file of the present invention is "Hiragana Heading"
, consists of four types of headings: ``Katakana headings'', ``Kanji headings'', and ``English headings'', but French,
Even if headings are provided in other languages such as German, the gist of the present invention will not be diminished.

(Effects) As explained above, according to the present invention, in the kana-kanji conversion processing device, hiragana headings,
4F of katakana headings, kanji headings, and English headings! ! By storing the types, there is no need to switch modes during input even if there are different character types in the input sentence, which has the effect of improving the operability of input work.
