Abstract

PURPOSE:To reconvert an input character string, which is converted to a Kanji (Chinese character) once, to a character type other than Kanji only with the operation of a character type conversion key by providing a means which converts the kanji in a sentence with mixed Kanji to a character string having the same reading. CONSTITUTION:An INV key controlling part refers to a conversion word table on the basis of the address indicated by lower bits 0-9 of information in a page memory PM1. A reading corresponding to the conversion word displayed on a CRT at this time, namely, the first character string is written in the head part of a block of the conversion word table. The INV key controlling part changes the second character string on the page memory PM1 to the first character string. Since the number of characters in the first character string is larger than that in the second character string generally, information in the page memory PM1 is all shifted by the difference of the number of characters to prevent the drop-out of information.

Description

[Detailed Description of the Invention] The present invention allows inputting the first character such as kana or romaji,
The present invention relates to a character processing device that selects a desired second character from a second character group such as kana and kanji characters corresponding to the Roman alphabet and converts the first character into a second character.

An object of the present invention is to provide a kana-kanji conversion processing device that can convert a character string input in kana into kanji and then reconvert the input character string into a character type other than kanji.

An embodiment of the present invention will be described below with reference to the drawings.
Before starting the explanation, the terms used in this embodiment will be briefly explained.

The first character or first character string refers to a character or character string that is initially input to the device.

The second character or second character string refers to a character or character string resulting from conversion of the first character or first character string by the present device. Further, the second character string is not uniquely determined and may partially include a plurality of converted characters.

The conversion unit refers to a range of characters or character strings specifically designated for conversion into a second character string within the first character string.

The conversion word refers to a character or a character string that corresponds to a conversion unit included in the first character or the first character string, among the second characters or the second character string.

A word is the smallest unit that constitutes a converted word.

That is, the conversion word consists of a single word or a plurality of words.

The above terms will be explained using specific examples. now,
If the input character string ``Una 1'' is converted to the output character string ``basic'', each of the above terms becomes as follows.

If there are multiple conversion words, this key indicates that the one conversion word displayed on screen 1 is the correct conversion word, and the key 29 indicates that it is an incorrect conversion word. By pressing this key 29, other converted words are displayed on the screen. Therefore, by pressing the key 29 until the correct converted word is displayed on the screen 13 and pressing the key 28 when the correct converted word is displayed, the correct converted word is selected.

The key 30 has the same function as the key 29, but the display order of converted words is reversed from that of the key 29.

The key 31 converts the displayed second character string (conversion @) to the first
This is a key that instructs to convert to a character string (conversion unit).

32 indicates the first character string inputted from the key group 15, which is converted into a second character string by the processing section and sent to the screen 13.
Enter the character corresponding to a single kanji from the automatic conversion mode displayed above or the key group 15, display all kanji corresponding to the input character on the screen 13, and select the desired kanji from the displayed single kanji. This key is used to select the single kanji input mode for selecting kanji.

33 indicates a direct input mode in which the kanji food is directly input using the numerical keys 34, and an indirect input mode in which the first character string is input using the key group 15 and the tJ2 character string is output from the processing ring section. This is the key to select.

The operation for inputting data according to the original shown in FIG. 2 using the keys having the functions described above and obtaining the output as shown in FIG. 5 on the screen 13 will be explained.

When inputting in hiragana, first, initial reset is performed using key 25, then key 16 is set to Japanese mode, key 17 is set to kana mode, and key 19 is set to hiragana uppercase mode.

However, since the character 37-1 indicated by a circle in FIG. 3 is a lowercase hiragana character, the key 18 is pressed to input this character.

Then, as shown at $311, press the key 23 to signal the start of inputting characters to be converted into kanji, operate the key group 15 to input the kana "konkai" to be converted to kanji, and then press the key 23. Press to notify that you have finished entering the characters to be converted to kanji, then enter the kana ° ","
Enter the information in kana in sequence as shown in Figure 3.

As will be described later, in the character conversion device according to the present embodiment, by inputting symbols indicating sentence breaks such as dots "," circles ".j" from the keyboard 12, the second character is converted from the first character string. Point 36 starts the conversion to a column.
is input, the second character string is displayed on the screen 13 as shown in FIG. Then, the input continues as shown in FIG. 3, and when the last circle 37 is input, all #! as shown in FIG. 2 character strings are displayed.

Note that the symbol 35 in FIG. 3 is a symbol indicating that the key 23 has been pressed.

In FIG. 5, the converted words marked with a symbol 38 (*) indicate that there are homophones other than the displayed word. In other words, symbol 38
Conversion words that are not marked are conversion words that are uniquely determined for the input characters.

Once all input has been completed in this manner, the next step is to press the key 26 and the cursor 39 will be placed at the position of the first symbol 38-1.

Since the conversion word "basic" indicated by this cursor 39 is a correct conversion word, when the key 28 is pressed, the cursor 39 moves to below the next symbol 38-2.

Since the conversion word "hereafter" indicated by the cursor 39 is also a correct conversion word, when the key 28 is pressed, the cursor 39 moves to below the next symbol 38-3.

The conversion word indicated by the cursor 39 is incorrect, so when the key 29 is pressed, the next homophone ゛Intended 1 is the said ``Return''
is displayed on the screen 13 instead.

This conversion word "plan" is the correct conversion word, so key 28
When you press , this conversion word "Intension 1" is selected.

Once all editing is completed in this way,
By pressing , the second character string displayed on the screen 13 is recorded as is on the recording paper 14.

Next, to explain the device in more detail by taking as an example the case of inputting in the reamed character mode, the key 16 is set to the Japanese mode, the key 17 is set to the Party-M character mode, and the key 19 is set to the Hiragana uppercase mode. Enter the information in the order shown. However, when entering the character 40 indicated by a circle, the key 18 is pressed.

The contents of the manuscript input as described above are processed within the device,
For example, as shown in FIG. 5, the text is displayed as a mixture of kanji and kana.

In the above process, if there are multiple sets of kanji with the same sound, they are displayed with * as shown in FIG.

(Example: *On the way home) Here, * is used to inform the operator that there are two or more homophone kanji (converted words).

If multiple homophone kanji (conversion words) exist for the reading of the input manuscript, the necessary kanji (conversion words) are selected by the following means.

For example, the cursor symbol CC is moved to the position of 0*" in the display of "°*Basic" in FIG. Such movement shall be made by FJDIT.
This can be done automatically by operating a key. Since the kanji that is currently selected is the kanji that is being displayed, the YES key is operated. Then, the cursor symbol C
C will automatically move to the "*" position of "* and after" to be selected next.The kanji you want to select now is "transition", so
To call up a kanji that is not displayed, the NO flat key is operated. Then, ゛after'' disappears from the display screen and ``majesty''
is displayed in the same location. When the NO flat key is operated further, the above display procedure is performed as shown in Table 1, and when the currently required "transition °" is displayed, when the YES key is operated, "transition" is selected, The device is cursor symbol CC
automatically shifts to the next "* return trip" position,
Informs the operator of the position of the next selection target.

...By repeating the same key operations as above,
You can finish your selection.

Here, the above-mentioned selection 11--functions for improving stretchability will be explained using Table 2.

When the result of pressing the NO flat key is ``*Transition-'', if you press the NO flat key again, °*Transition item'' is displayed. (Table 2. 6th line) Here, the kanji character corresponding to ``Ikou'' ( All conversion words) will now be displayed.
When you press the plain key, “*after” is displayed again in the first place.
is output. By constantly displaying items repeatedly in this way, the ease of selection is improved. Next, when you press the BACK key, the display is completely opposite to when you press the NO flat key. That is, "*Transition item 2" is displayed again, and further, by operating the BACK key, "*Transition" is displayed.

Here, the transition can be selected by operating the YES key as in the previous case. The following is the same as last time.

...Next, for things that cannot be corrected using the above method, it is necessary to be able to easily return them to the original first character (the corresponding conversion unit). For this purpose, use the INV key.

First, move the cursor using the method described above (EDIT key or Y
method using the ES key) or CUR8OR8HI
F'l' key (CU几SUR, 8l-LIFT key is 1
(You can move the cursor by one character by operating), move the cursor symbol CC to the *" position corresponding to the kanji you want to convert to the first character. Now operate the INV key. As a result, the second character is converted into the first character and displayed.

This situation is shown in Table 3.

The method for automatically converting a first character string into a second character string in the process of converting it has been described above.

Next, a method for inputting kanji characters one by one will be described.

There are two methods for inputting kanji units. One is an indirect input method and the other is a direct input method.

First, set the automatic single kanji selection key M section to the single kanji side,
Next, the indirect/direct selection key IDK is set to the direction desired by the operator. Thereafter, the cursor symbol CC is shifted using the cursor shift key C8K and brought to the corresponding position desired for input.

When the indirect direct selection key IDK is set to the indirect side, input kanji using the following procedure.

First, press the kanji shift key KK23 shown in FIG. 1, and then input the reading of the kanji. The reading of the kanji is p-maji.If the kana selection key order is romaji, enter the reading of the kanji in ta-maji.
Also, if RKK is a kana, enter it in kana. The pronunciation of a kanji can be input using all+ for the tuning fork, or only a part of the pronunciation of the kanji can be input from the beginning. After that, press the Kanji shift key KK again and screen 13 will appear.
The corresponding kanji are listed as shown in FIG. 30 T1. The listed kanji groups correspond to the keys in the second row from the bottom in FIG. 1B, including the English letters keys A, 8, . D, F, G, H
, J, and L, ; respectively.

Next, if a desired kanji is displayed, the user presses the key corresponding to the position of the kanji to input it. If the desired kanji is not displayed, press the "8" key or the space key to display the kanji group following the kanji group on the IJl and l# sides, and enter the desired kanji in the same manner as above. For example, in Figure 32, if you change ``hon'' at position T2 to ``kira'' or move the cursor to position T2 using the cursor shift key 08K and press the single kanji selection key, the entire screen disappears and the cursor moves to the top. Move to the bottom left. After that, as mentioned above, press the Kanji shift key KK, "U"
, by pressing the kanji shift key KKt-, kanji starting with "u" are listed as shown in T1 in FIG. 30. If the key r8J corresponding to ``Ki'' is pressed here, the character ``Kai'' is entered at the T2 position, the data is corrected and displayed on the screen, and the cursor advances to the next character position. A single kanji input control section, which will be described later, performs the above-mentioned control.

In this example, the operator's standard finger pairing,
For example, the middle finger of the right hand is 9 + I + K e ”! +
It is used to input 2, ノ, and ne, and is structured so that pressing any of the keys will specify the third character from the left in Figure 30, which corresponds to the middle finger of the right hand. .

If the indirect direct selection key is set to the direct side,
The direct human input means DIH for Kanji characters can input the Kanji code into the data buffer corresponding to the current cursor position, and display the Kanji code at the current cursor position. After input, the cursor automatically advances to the next position. This direct input means is capable of inputting not only kanji but also kana alphanumeric characters and other symbols.

Since a single kanji can be input as described above, it is also possible to easily input idioms that are not in the word dictionary file, and it is also easy to correct kanji that have been erroneously converted during conversion.

In the manner described above, sentences can be created easily and quickly.

Next, when the print key is operated, the displayed text is printed out. In this case, multiple - homophones (conversion words)
The * symbol indicating the presence of
The blank space after "Year" is deleted and the data is recorded concisely.

Although the most basic operation of the character conversion device according to this embodiment is as described above, this character conversion device will be explained in more detail using the drawings.

PM2 is a page memory and has the same configuration as PMI.

The contents of this memory can be displayed on a CRT similarly to PMl.

WF is a word file, and as shown in FIG. 11, the pronunciation of a word (kanji) is a keyword, and the character hood of the word, grammatical information, etc. for the pronunciation of the unit tr4 are entered.

In this example, a storage capacity of 32W is prepared for one word,
The breakdown is as follows: IQWO for the reading of the word (kana heading)
RD, 3 WORD for the part that does not change depending on the reading of the unchangeable kana part (for example, 9 beautiful 1 no 1 shi).

5 WORD for word character code, I for part of speech information
I WORD for information on the conjugated form of WORD1.

I WORD for affix information, 4WO for field information
I (IWORD for the number of DS kanji, that is, the enemy information of the character code entered in the character food column.

IWORD for information on the number of reading codes written in the unchanged kana part.IWORD1 as frequency information.

It consists of 4 WOR and D allocations as vacancies.

The part-of-speech information is as shown in FIG. 10, in which each bit of the IWORD is associated with a part-of-speech. This includes information such as prefixes and suffixes.Information on the conjugated form is as shown in Figure 11, which corresponds to each bit of the I WORD with the verb and the conjugated form of the adjective verb Tsubaki. .

As shown in FIG. 12, the affix information corresponds to each bit of I WORD.

Affix information includes place name, person's name, organization name, ground (things connected to place name, e.g. prefecture, city), extraction (things connected to person's name, e.g., Mr., Kimi), affix information (things connected to organization name, e.g. section, etc.). It is classified into such things as (association).

Frequency information was determined with reference to materials provided by the National Institute for Japanese Language and Linguistics.

As shown in FIG. 13, the field information is made by associating each bit of the IWORD with each field information.

The fields in which each word is frequently used are shown.

Note that the words stored in the word file WF can be the converted words.

As shown in Figure 14, in the single kanji dictionary @KV, the pronunciation of kanji is a keyword (sW), and the kanji code can be searched.

If there is a different reading for each kanji, a K i1' is created for that reading so that the reading of a kanji can be searched by both the sound and the kun.

Note that in this example, we have adopted the structure of 1 kanji for 1 kana heading, but if there are multiple kanji with the same sound, they can be combined into 1
Write multiple homophone kanji for the heading 1. It is clear that it can be made into a table.

PNT 1 is a pointer memory and has a storage capacity of 8 bits. This memory serves as an address register for specifying the position of the cursor symbol CC displayed on the display section of the display means and as an address register for reading and writing the page memory PMI.

PNT2 is an address register for reading and writing the page memory FM2.

Both PN1'l and PNT2 are 1 to 19 as address values.
Up to 2 have meaning. It is invalid when set to any other value.

That is, when bit 15=0 and bit 14=0, it is output as is.

When b-th 15=0 and bit 14=1, convert to the character code corresponding to "*".

B-th 15=1, bit 14=l O) Convert to poem and space code.

When bit 15=1 and bit 14=1, convert to space code.

The selector selects the output of PMl via the code converter and P
It plays the role of selecting one of the outputs of M2 in relation to the lock keys AMK and IDK.

The CRT controller has the function of displaying the output information from the selector in the form of a gesture and displaying a cursor symbol at the position specified by the pointer PN1'l.

Such a CRT controller is a character generator C.
Gfi: refers to and inputs a character code into the CG to generate a pattern of the character, and displays the character code in the page memory PM.

The display control circuit I) CO'I'' controls the display to display 12 vertical lines and 16 horizontal characters.

Therefore, if page memory PMl or PM2 does not contain a carriage return code or line feed code, a counter for counting the number of characters in order to display 16 characters per line in the display control circuit.
- A counter is provided to force the rows so that there are 12 rows.

In addition, the processing unit CPU uses the page memory P M and the pointer PN.
The timing to control T is when the display control control DCOT is 1.
This is done at the time of transition from line display to the next line display.

A CRT is a display unit that consists of a cathode, a ray, and a tube. Me& is displayed on the display section C under the control of the display control circuit DCOT.

Conversion parameter (1), conversion sentence buffer, conversion word table, conversion parameter (2), conversion unit table,
It consists of nested tables, single dictionary tables, etc.

Further, the EGI8TER includes a keyword register, a selection number register, an input sentence field register, a conversion σn field register, and the like.

Next, the details and mutual relationships of each parameter, buffer, table, system, and both parts will be explained. For individual explanations, in addition to using each drawing,
FIG. 18 will be used to explain the mutual relationship.

The converted sentence BUF is shown in FIG. The converted sentence BUF is a buffer for storing sentences to be converted. Under the control of the KBI input control section, which will be described later, the reading information of the sentence input from 1:31 is converted according to a predetermined format and stored.

The format of the converted sentence J3UF is as shown in FIG. All character information is expressed by JIS codes of kana and symbols. Also, special codes @ and ■ are used to indicate the portion to be converted into kanji (hereinafter referred to as conversion unit). The information stored under the control of the KBI input control section includes the text information and the special codes @ and @ka. @ specifies the beginning of the conversion unit, and ■ specifies the end of the conversion unit.

Conversion parameters MPAtl), MPA(2+ are
This is a parameter that specifies the range of information stored in the conversion sentence buffer to be converted into two character strings, and is set by the KB1 human control unit and becomes a parameter for subsequent conversion (see FIG. 20).

MPA(3) specifies the start address of the range excluding the range where the conversion has been completed. It is initialized by the KBI input control section and KPA(3)-
MPAfl).

MPA(4) is a register that stores an empty number in a conversion word table, which will be described later. The specific role of MPA (4) will be described later. MPA(4) is initialized by the INT key control section.

MPA(5) and MPA(ti) respectively indicate the first and last addresses to be converted when converting between the range to be converted, that is, MPAfl) and MPA(27).

The KBI input control unit is configured such that the AMK key is automatic and the KBI input control unit is
When there is an input from Bl, the operation starts according to a command from the main control section. After the operation is completed, control is returned to the main control section. The KB1 human control unit converts the information input from the KBI into the format specified by the conversion statement BUF, and then writes the information to the conversion statement BUF, and at the same time writes the information necessary for conversion into the conversion parameter (1). It plays the role of writing parameters and giving instructions to the conversion control unit to start conversion. For input from the KBI, it is possible to select between kana manual input and Roman alphabet input by operating the R and KK plain keys. In addition, when the KBI's Kanji shift key KK is pressed an odd number of times, it indicates the beginning of a conversion unit, and an even number of times it is pressed, it indicates the end of a conversion unit. The KBI input control unit converts the above input into a format specified by the above-mentioned converted sentence buffer, and writes the converted information to the converted sentence buffer.

The information stored in the converted sentence buffer is converted into a kanji-mixed sentence (second
Conversion to a character string) is started when any of the following conditions are satisfied, and when any of the following conditions is satisfied, an instruction to start conversion is given to the conversion control unit. .

1. In the input information from KBI, there is a symbol, for example [1,.

etc. existed.

2. When a kanji start code is generated by the kanji shift key.

3. When a certain number of characters are entered after the Kanji shift key is pressed twice.

4. When Hatsu 7A overflows.

The KBI input control section sets the conversion parameter (1) within this range before giving an instruction to start conversion to the conversion control section. At the same time, a reference range as related information for conversion is also set in conversion parameter (1).

In kana-kanji conversion, the information before and after a word is important, so when converting a word in the middle of a sentence to kanji, the kana-to-kanji conversion is controlled so that the information before and after is always added.

Activation of Romaji-kana conversion is performed by the KBI input control unit when inputting hiragana or katakana in Romaji mode using vowels (A, I, U, etc.).

The kana that corresponds to E, 0) or (X) on the keyboard (see Figure 1), ie, ni, na.

I, Ra] or [Sa], [C, 2, S, I.

This occurs when either [u] or [su] and their respective lowercase letters are entered. Conversion is performed with reference to the Romaji-kana correspondence table (FIG. 21). For example, "a"
When inputting ``Romaji'' on the keyboard shown in Figure 1, when the rAJ key, that is, the ``chi'' key is pressed in the hiragana shift state, the roman-kana conversion control unit is activated and the ``A'' is entered in the table shown in Figure 21. ” is extracted.

As shown in FIG. 22, the word dictionary table is a word dictionary W.
This is a buffer for extracting and storing only the information necessary for conversion from the information stored in F.
It has a capacity of 2x24W. That is, as mentioned above, 1 word 3
Since it has 2W members, information for type 2 words can be stored, and the stored information is sequentially numbered from 1 to 24 for each word. To write to the hondanai dictionary table,
This is performed by conversion control described later.

The net table is a table written by a conversion control unit, which will be described later, when finding a conversion word from each conversion unit, and has a capacity of 28×8W as shown in FIG. 23.

This embodiment has a function of automatically dividing a conversion unit. For example, 8 basic texts. For the conversion unit , C automatically becomes 8 kihon. It is divided into two parts: text. The number of divisions is not limited to two as in the above example.

In this embodiment, up to eight divisions are allowed. The words obtained by division are either independent words, prefixes, or suffixes. This nest table stores information about this division. There is a 28W information storage field FJr for the 6 divided candy.

In FIG. 23A, (g) is the address in the K1 sentence buffer where the pronunciation of the word is stored.

(c) is the number of readings of f, lj. 0 is the number when there are multiple candies that correspond to the reading of the compound word.

0 is the first number of the word dictionary table that stores the word dictionary information corresponding to the dti (1 of the word dictionary table mentioned above).
~24 numbers). ■ is a number in the word dictionary table in which word dictionary information corresponding to the compound word is stored.

It is now assumed that a conversion unit called "Lokihontekiro" is stored at the head of the conversion sentence buffer, and a nest table corresponding to the conversion unit is written by a conversion control unit, which will be described later. At that time, it is divided into "kihon" and "1-tekki", and the character string (candy) corresponding to the musician is "°basic", and the character string (word) corresponding to the latter is "enemy", "drop", "suit", etc. 4 of 1
Assume that a seed is found by a conversion control unit, which will be described later. An example of the nest table at this time is shown in FIG. 23B.

The conversion parameter (2) is written by a conversion control unit, which will be described later, when converting a conversion unit into a conversion word, and includes various parameters. As shown in FIG. 24, they have a capacity of <9W and are named from Mcwto to MCW+91.

MCW (1) is a register in which the conversion control unit, which will be described later, writes the start address of the conversion unit found from the specified range of the conversion statement buffer (range specified by conversion parameter (1)). be.

MCW+2) is the length of the conversion unit.

M c W (3) is the start address of a word in the conversion unit that is actually searched in the word dictionary WF by a conversion control unit, which will be described later.

MCW(4) is the length of the word for which the search is performed.

MCW (51 is a register in which the number of words obtained as a result of the search is entered. However, when it is negative, it indicates that the corresponding word did not exist as a result of the search.

MCW (6) is an empty house in a word dictionary table that stores the 6 word dictionary searches obtained as a result of the search, that is, a vacant room in the word dictionary table that is defined by MCW (6) from black to 24. This indicates that the space between the tables is empty.

MCW(7) is the number of divisions in the conversion unit division.

MCW (8) is a register in which the number of converted words corresponding to the conversion unit is written. A positive value indicates the number of converted second character strings, and a negative value indicates that the conversion was not possible.

MCW (9) is the number of words whose "certainty" (described later) exceeds a certain threshold value among the MCW (8) conversion words.

The conversion control section starts operating in response to instructions from the KB1 manual control section, and returns control to the KBI input control section after completion.

This control unit converts the range defined by the conversion parameter (1) of the information (first character string) stored in the conversion sentence buffer into a second character string, and stores the result in the nest table and word dictionary. Write to table, conversion parameter (2). After that, it takes on the role of activating the conversion unit table creation control section and the conversion result processing control section. Here, the concept of the conversion control section will be described. The conversion control unit first converts MP person 3) to M.
Search for a conversion unit within the range of PAi2). When the conversion unit is found, set MCW (11, MCW (23). At the same time, set MCW (23) to clear the word dictionary table.
W (set 61 to 1. Next, search the word dictionary WF and find the conversion word corresponding to the conversion unit, M
Keywords of the word dictionary WF are set in OW+3) and MCW4). Naturally, first of all, MCW
(3) = MCW (1), MCW14) = MCW (Set as 27. Also, give 1 as an initial value to MCW (7). (MCW (7) will be described later.) Search is performed by the conversion control unit. The search control is performed by searching the word dictionary WF for dictionary information corresponding to the keywords set in MCW(3) and MCW(4), and applying the results to the word dictionary. Table and MCW (5
). If found as a result of the search, MCW
Set the number in L5) and set the MC in the word dictionary table.
Dictionary information is stored starting from the position indicated by Wf61. If no result of the search is found, -1 is set in MCW (5).

After the above operations of the search control section are completed, the conversion control section examines the search results. If MC'W+5+ is negative, 1 is subtracted from MCW4) and the word dictionary is searched again by the search control unit. until the appropriate word is found.
Repeat this action.

If the corresponding word is found, that is, if McW (1'i) is a positive number, the state at that time is written into the nest table. That is, MCW (31 to 823 (G)), MCW (
4) to (b), MCW (5) to C) d, MCW16)
ヲ(L) GC save.

In addition, in (2), enter the corresponding numbers in the word dictionary table in which the dictionary information of the corresponding word is stored, as many as the number set in MCW (5).

If there is a residual part in the conversion unit in the previous search, MC
Add 1 to W(7) and perform a word dictionary search for the remaining part of the conversion unit in the same manner as the previous time. At that time MCW+
3) and MCWi4) are changed to the address and length indicating the remainder. However, if the corresponding candy is not found in the search for the remaining portion, the candy found in the previous search when written to the nest table is canceled. Therefore, at this time, MCW (from 71 to 1
, and already committed to the nesting table. If the word dictionary search for the remaining part is successful, save MCVVL3) to MCW+6) in the nest table as before, enter the specified items in (9) of the nest table, and if there is still a remaining part. Repeat the above explanation from time to time.

In this way, the conversion unit is converted into one or more candies. The above process: The number of divisions of the conversion unit is written in MCW (7).

The conversion is completed above, but if the conversion is not possible in the end, MCW (force = 1, MCW (5) = -1
.

It is clear from the above description that MCW(4)=1 is set.

After that, if the conversion is successful, the conversion control section activates the conversion unit table creation control section, and then activates the conversion result processing control section. Also, if the conversion is unsuccessful, MCW (8)
is set to -1 and the conversion result processing control section is activated.

After the conversion result processing control unit finishes its control, the conversion control unit again searches the conversion statement buffer for the next conversion unit to be converted. If it exists, the above control is repeated. After converting the entire range specified by the conversion parameter (1), the conversion control section returns control to the KBI input control section. The KBI input control section transfers its control to the main control section as described above.

The conversion unit table is a place for storing combinations of words (sometimes only one word) corresponding to conversion units, and is a table in which the certainty of conversion for each combination is entered. The conversion unit table is as shown in Figure 25.
It has a capacity of 1X24W. l1w for each combination
It has a capacity of Therefore, a total of 24 combinations can be stored. For example, as mentioned above, suppose that for the conversion unit wakihonteki, one and four words corresponding to ``5 kihon'' and ``teki'' are obtained, respectively (this information is recorded in the nest table). , four combinations of 1×4 can be created as combinations of both. 11w of information is stored for each of these four combinations.

The first 8Ws define combinations of words, and their numerical values are the numbers of word information stored in the word dictionary table. The next IW is a field in which to enter the number of words, that is, the number written in the first 8Ws, and the next IW is a field in which to enter the part of speech of the combination as a whole. For example, the compound word ``basic'', which is a combination of ``basic°'' and ``target'', is considered an adjective verb. The next IW is a column in which the "certainty" of the combination is entered. Writing to the conversion unit table is first performed by the conversion unit table creation control section, and then "certainty" is performed.
Regarding the column ・ indicates the grammar weight control section, which will be described later.
It is modified by a frequency weight control section, an affix weight control section, and a field weight control section.

The main function of the conversion nest position table creation control section is to create the conversion unit table. When creating the nest table and word dictionary table conversion parameters (2
). Also, in MCW (8), the number of types of candy combinations entered in the conversion unit table, that is, the number of conversion words, is entered.

Next, write down the part of speech and conjugation of the combination as a whole. The problem here is which one to select from among these multiple conversion words.

Therefore, in order to modify the "certainty" term of the conversion unit table, the grammar weight control section, frequency weight control section, connection weight control section, and field weight control section are activated.

With the above steps, the conversion unit table can be completed.

Next, set MCW + 9), but as mentioned above, MCW < ta can be the number of types of word combinations written in the conversion unit daple, but here we will use another setting method, Let me explain it.

That is, it is defined in terms of the number of thresholds equal to or higher than a certain threshold, taking into consideration the certainty modified by each of the weight control units.

Further, the threshold may be always constant or may be changed depending on each conversion unit. The threshold is determined by a threshold determination control section included in the conversion unit creation control section. This makes it possible to eliminate the output of converted words that are clearly erroneous.

The grammatical weight control unit performs a grammatical check and weights each of the second character strings converted from the conversion unit. The grammar check is
Perform within the reference range indicated by MPA(5) and MPAI61. Started by the conversion unit table creation control section,
After completion, control is returned to the conversion unit table creation control section.

The grammar weight control section is roughly divided into two parts. One is that the converted sentence buffer is divided into a front grammar check section that checks the connection with the hts part of the conversion unit, and a rear grammar check section that checks the connection with the rear part.

The front grammar check part checks whether the front part of the anonymous permutation unit is a case particle when the second character string is a verb. If it is a case particle, it increases the weight and At the same time, reduce the weight.

The rear grammar check section is further divided into two parts.

One is an invariant kana part check that checks whether the character following the conversion unit matches the pronunciation of the invariant kana part in the word dictionary table, and the other is This is a conjugation check that checks whether it matches the conjugation of a verb, etc.

The conjugations of verbs, adjectives, etc. have regularity in their changes, as is common knowledge, and once the type of conjugation of a verb is determined, the letters that follow it will inevitably be determined. Both the unchanged kana part check and the conjugated form check play an important role in determining the "certainty" of the second character string.

ME calculation of weights is performed for all second character strings listed in the conversion unit table.

The frequency weight control unit is responsible for frequently checking and weighting each of the converted words converted from the conversion unit. This control section is activated by the crucian carp unit table creation control section, and returns its control to the conversion unit table creation control section after completion. The frequency weight control section is
Control is performed by obtaining frequency information of the six words listed in the conversion unit table from the word dictionary table and adding it to the weight of each second character string.

The connection table (1), as shown in FIG. 26, is a table showing connection relationships between parts of speech, prefixes, or suffixes of independent words. The numbers in the table indicate the degree of connection between each element.

However, although this number was determined empirically, it can be approached to a better value by arbitrarily changing it. The X mark in the figure indicates a very low possibility of connection.

The connection table (2), as shown in FIG. 27, is a table showing connection relationships based on the connection information shown in FIG. 12. The view of the figure is the same as the connection table (1).

The connection weight control unit is responsible for performing a connection check and weighting each of the single side or plural conversion words converted from the conversion unit. This control section is activated by the conversion unit table creation control section, and returns to the conversion unit table creation control section after the operation is completed.

This control section is roughly divided into two parts. One is a continuation check section (part of speech) using the affix table (1), and the other is a semantic connection check section using the connection table (2).

In either case, when the second character string consists of two words, the part-of-speech connection checker checks the connection between the two words. However, the part of speech of the 6 edicts can be obtained by referring to the word dictionary table from the storage number of word dictionary table 1 written in the conversion enthronement table, and the weight of their connection can be obtained from the connection table (1> This weight information is added to 1m (field) of "certainty" in the conversion unit table.

The semantic connection checking unit checks the connection between two words constituting the second character string based on their semantic relationship. The connection information shown in FIG. 12 is obtained by classifying words from this standpoint. The connection information for the six words can be obtained by referring to the word dictionary table from the storage number in the word dictionary table written in the conversion unit table, and the weight of these connections can be obtained from the connection table (2J Th et al. This weight information is added to the certainty column (field) of the conversion unit table.All second character strings written in the conversion unit table are weighted.

Field information as shown in FIG. 13 is set in the conversion word field register in EGISTgl(, in FIG. 17, but there are two cases for this setting.

One is the case where the words are uniquely determined by kana-kanji conversion, and is it the field of uniquely determined words in the conversion unit table? # information is set in the conversion word field register by the conversion result processing control unit. Of course there are 1 homophone words
In the case where there is one, it is treated in the same way as above, as it is determined by -M. In the other case, when one word is selected using the YES key or NO key in a state where there are multiple homophones and cannot be uniquely converted, the field information of the selected word is retrieved from the conversion word table. Enter into the converted word field register by pressing the YES key control unit. Conversion word field register is 2WO
If there is an RD and two or more compound words, ie, words, are in one conversion wheel position, the field information of the two words is entered in the converted word field register.

The field information entered in the converted word field register is added to the information in the humanities field register by the field determination control section. The input sentence field register consists of 16 words, with 1 word assigned to each field. For example, if words with a bit set in the literature field have been manually written 28 times, law 20 times, company 1 degree, science 2 times, and home 4 times, then the above input sentence field The 16 words in the register are 28.20, 10, 2.4, respectively. , that is, as shown in FIG. 13 (0, 28, 20, 10, 2, 0° 4.0.
0.0, 0.0.0, 0, 0, 0) are stored.

Here, the field information in which only the literature item is set in the conversion word field register, that is, one field information WORD in FIG.
, 0, 0° o, o, o, o, o, o) is set, the field determination control section adds each bit of the converted word field register to each WORD of the input sentence field register. . Therefore, in this example, 1 is added to the WO number in the field of literature, and the word in the field of literature becomes 119. Therefore, in this example, each WOR, D of the input sentence field register
The value of is (0,29°20.10,2,0,4,0.0.
0.0. ．． 0.0°0.0.0).

The field weight control unit checks each of the single side or plural t42 character strings converted from the conversion unit using the field information, and sets the weight for each of them.
Responsible for making mistakes.

This control section is activated by the conversion unit table creation control section, and after the operation is completed, returns control to the activated control section. As shown in 74- of FIG. 50, weighting is performed based on the field information, and the contents of the input sentence field register mentioned above and the field information of each of the singular side or plural conversion words are used for each field. After multiplying, the above multiplication results are summed for each converted word and used as the basic data for the weight information of each converted word, and the balance with other weight information such as weight information from grammar check etc. is adjusted L. A correction constant, for example, multiplied by 30 is added to the AC of each corresponding word in the conversion unit table of FIG. Weighting based on field information is performed using the method described above.

The conversion word table is a table in which the information on the conversion results compiled in the conversion unit table is compiled for display on a CRT. FIG. 28 shows the format. The capacity is 1024W. One block is assigned to correspond to one conversion unit. One block consists of a HEAD that provides a fixed value for that block and a plurality of records that correspond to a plurality of conversion words.

HEAD part includes 1 unit, iRN, iDN, kcL, IC
1 consisting of 5 items of C, iCC is 20W, others are 1W. iRL is the record length, i几N is the number of records, iCL is the number of characters in the kana reading of the conversion unit, iC
C is the character code of the kana reading of the conversion unit. iDN
is a register indicating the number of the conversion word displayed in CR'f'. For example, when the conversion word written in the third record of a certain block is displayed, the iDN is 3. Also, if the kana reading of the HEAD section is displayed, it is set to 0.

Records are 1FL1, 1FL2, iAC, iK
Consists of 4 items C. 1FLl, 1FL2
, iAC is IW, and iKC is generally several W (variable length).

Each record is the conversion result of the conversion unit, that is, a strange word enlarged with the shadow of a character code.

1FL1 is an item for entering the field of the converted word, and is the same as that described in the word dictionary. i FL2
is used to enter the field corresponding to the second candy when the converted word consists of multiple words.

iAC is the "certainty" of the conversion word. This is already described in the conversion unit table.

iKC is the character code of the converted word.

Note that the length iKL of the iKC is determined by the maximum length of the character code string of the conversion dn. For example, if "city" and "year" are selected in response to the conversion word "°toshi", a love out code (all 1s) is added after the year to match the lengths.

The conversion word table is initialized by the conversion result processing control unit. Also, the iDN is initialized to 1 by the conversion result processing control section, and the BACK key control section, IN
It is changed by the V key control section and the NO flat key control section.

Single kanji selection table FIG. 29 is a comparison table showing PM2 addresses for input data from the keyboard.
Used for single kanji selection control in single kanji input.

The conversion result processing control unit writes the results obtained by the conversion control unit and the conversion unit table creation control unit to the page memory PMI for display at (41,T), and
It plays the role of creating a conversion word table in preparation for changing the displayed characters according to the operation of the HACK key, INV key, NO key, etc. by the operator.

The conversion result processing control unit first converts the contents of the converted sentence buffer in the range indicated by the conversion parameter (1) to P indicated by PNTl from the beginning until the V character shift code @ is found.
Move into M1. Of course, 1'NT1 is incremented sequentially. If @ is found, MCW (9
) to judge whether it is positive or negative.

When MCW19) is negative, that is, the conversion word corresponding to the conversion unit is not found, the conversion parameter (1), the range indicated by M P A (2), or the kanji again from after the kanji shift code @. Until you find the shift code @,
Information is moved from the converted sentence buffer to the page memory PMI. However, the transfer of the Kanji shift release code @ shall be omitted.

When MCWf9) is 1, that is, when one conversion word corresponding to the conversion unit is found, the word dictionary table number corresponding to the conversion word written in the conversion unit table is converted to a character code, and the PNTI Write to the page memory PMI indicated by . At this time, PNTI is incremented sequentially. Next, the field of the converted word is set in the converted word field register, and the field determination control section is activated. When the control returns from the field determination control unit, the conversion parameters fl), MPA (2
) or until the Kanji shift code @ is found again. Information is moved from the converted sentence buffer to the page memory PM1. .

MCWf9) is 2 or more, that is, when multiple conversion words corresponding to the conversion unit are found, the conversion parameter M P
A + 4) bit, L5 set to 0, bit 4 set to 1, written to PMi indicated by t-1PNTI, PNT
Increment 1. Next, writing of the conversion word table is started. The format of the conversion word table is as described above. The conversion result processing control unit refers to the conversion unit table and extracts MCW (91 conversions) from the conversion unit table in order of "certainty". By referring to the word dictionary table, the character code and field of the conversion word are extracted. Find the information and write it into the conversion word table.

Also, the Ag of the pull-tsk written in the conversion word table
The reading of the conversion unit and other information are written in AD. At that time, enter 1 in iDN.

If you have finished writing to the conversion word table, MPA
f4). Thereafter, the character code corresponding to the first code of the block just written to the conversion word table is written into the PMI again. In that case, even if a dumpout code is written in the character code, it shall be written without omitting it. However, as mentioned above, the love-au F code is displayed as a space on the CRT. Once you have finished writing the conversion word, start again with the conversion parameter t1, starting from the Kanji shift release food @ of the conversion unit.
), the information is moved from the converted sentence buffer to the page memory PMI until the range indicated by MPA12) or until the Kanji sifushiconide @ is found again.

This concludes the explanation of the case where MCWf9) is negative, the case where it is 1, and the case where it is 2 or more. Next, the conversion result processing control unit sets a parameter MPA13) that specifies the conversion end range +1.

The set value of M P A+31 is set to the address N after the information is transferred from the converted sentence buffer to the PMI +1.

Next, the conversion result processing control unit checks whether the number of conversion words corresponding to the conversion unit is 1 or not, and if it is 1, writes the field of the conversion word into the conversion word field register. Start the field determination control section. When control is returned from the field determination control section, the conversion result processing control section returns the control to the conversion control section.

The field determination control section adds the data entered into the conversion dΔ field register as described above to each field of the input sentence field register. Therefore, if the contents of the learning word field register are added one after another, the input sentence field register will overflow, but the field determination control unit is designed to prevent such overflow by adding all the input sentences when the addition result is 31 or more. Control is performed to erase 1 from the text field register. The field determination control section is activated by the conversion result processing control section or the YES key control section, and after the control is completed, the control is returned to the activated control section.

The print key control unit has the role of outputting the information stored in the page memory to the outside. It is activated by the main control section and returns its control to the main control section after the operation is completed. The print key control unit outputs the information from the beginning to the end of the page memory PMI to the output device [OU, but at this time, it does not output anything other than bit 15 = bit 14 = O because it is a control code. The cursor shift key control unit has the role of moving the cursor displayed on the CRT one by one. It is activated by the main control unit and returns the control to the main control unit after the operation of the cursor shift key is completed. The cursor shift key control unit has a function of incrementing PNTl in order to shift the cursor.

The BDIT key control unit has the role of searching the second character string on the display screen for locations where a plurality of conversion words exist. E
The DIT key control section is activated by the main control section and returns its control to the main control section after its operation is completed.

The EDIT key control unit scans the page memory PMI and searches for a position where bit15=o and bit14=1. When scanning the page memory PMI, the PNTI is sequentially incremented, so by ending the operation of the control unit at the position where the information is found, PNT 1 can be automatically set at the position of the information. Since the information means that there are multiple converted words that follow it, the above operation allows searching for locations where multiple converted words exist in the second character string,
On the CRT, a cursor symbol CC is displayed at the position of the * mark displayed in front of the conversion word.

When the first character string is converted into a second character string and there are a plurality of converted words, the YES key control unit converts the second character string displayed on the CRT out of the plurality of second character strings. CB, T It also has a function to search for the position of the second character string to be selected next.

The YES key control section is activated by the main control section, and returns its control to the main control section after its operation is completed.

The YES key control unit first selects the P that the PNTI is pointing to.
Check whether the information in MI is bit15=0 and bit14=1. If bit15=o and bit14=
If it is not 1, the control is immediately returned to the main control section. In another example, bth 15=.

If bit 14 is not 1, the control may be transferred to the control from the 14th line onward on the next page. If b-th 15=0 and bit 14=1, the following operation is performed.

The YES key control unit selects the PMI indicated by PNT 1.
The conversion word table is referred to by the address pointed to by the lower bltO-bit9 of the information in the table. The I-I Fi A D section of the block in the conversion word table currently contains CR,
The record store that stores the conversion word displayed on T is stored in iDH. The field of the converted word is stored in the record.

The YB8 key control section writes the field information into the converted word field register and activates the field determination control section.

When the control is returned from the field determination control section, the YES key control section selects the C which is currently pointed to by the cursor symbol CC.
Page memo corresponding to the * mark on RT! J Set bit 15 of the PMI content to 1. As a result, the DCOT (display control circuit) changes the * mark that has been displayed on the CRT to a space.

Next, search for a conversion word on the CRT to be selected. This function is
It is basically the same as the DIT key control section. However, ED
The difference is that the IT key control section scans from the beginning of the PMI, whereas this control section scans from the location currently pointed to by PNT 1 onwards.

This completes the operation of the YES key control section.

The NO key control unit converts the first character string to the second character string, and when there are multiple second character strings, the current CRT
It plays the role of displaying other second character strings instead of the second character string displayed above.

The NO flat key control section is activated by the main control section and returns its control to the main control section after its operation is completed.

For the NO flat key control, first press the P that PNT 1 is pointing to.
Check whether the information in 41 is b-th 15=0 and bit 14=1. If bit 15=O and bth 14
If it is not equal to 1, the control is immediately returned to the main control section.

If bit15=0 and bit14=1, the following operation is performed.

The NO plain key control section first selects the lower bi of the information in the PMI.
The conversion word table is referred to by the address pointed to by t O-bit 9. In the HEAD portion of this block of the conversion word table, the record number storing the conversion word currently displayed on the CRT is stored in the iDN.

The NO flat key control increments the current iDN. At this time, if the iDN exceeds the total number of records 11 (N), change the IDN to 1.

Therefore, the NO flat key control will
The DN is rotated in a fixed direction within the range from 1 to iRN. After that, the NO key control unit picks up the character code stored in the record corresponding to the iDN that has just been changed, and writes the page memo! j Change the relevant information in PMI. After the above operations are completed, control is returned to the main control section.

The BACK key control section is almost the same as the NO flat key control section. The difference is that the NO flat key control is the iDN of the conversion word table.
is rotated in the increasing direction within the range of 1 to i 几N, whereas the BACK key control section is rotated in the decreasing direction.

The INV key control unit plays the role of converting the second character string (conversion word) into the first character string (conversion unit).

The INv key control section is activated by the main control section and returns its control to the main control section after its operation is completed.

The INT key control unit first selects the lower order b of the information in the PMI.
It refers to the conversion word table by the address pointed to by bits 0 to 9. H1i! of the block in the conversion word table! In the AD section, the reading corresponding to the conversion word currently displayed on cit'r, that is, the first character string is written. INv key control section is page memo IJPM
The second character string on I is changed to the first character string.

Generally, the first character string has more characters than the second character string, so all the information in the page memory PMI is shifted by that amount to prevent information from being lost.

After the above operations are completed, control is returned to the main control section.

The INT key control unit includes all control units and various memories,
This is a control unit that initializes registers, etc., and is activated by the main control unit when text input starts. After the operation is completed, control is returned to the main control section.

The DIN input control section reads data from DIN, the means for directly specifying and inputting Chinese characters as described above, and controls inputting it into the PMI. That is, when the AMK inputs single kanji characters and the IDK inputs directly, data is read from the DIN and output to the PMI.

The single kanji input control section sends data from the FIFO, that is, the reading of the kanji, to the keyword register when the AMK is inputting a single kanji. The KF search control unit refers to the KF, that is, the kanji file, based on the reading of the kanji entered in the keyword register, and sends the corresponding kanji group to address PNT2 of page memory 2 (PM2). The kanji group that has entered PM2 passes through DCOT and is displayed on C) tlT under the control of the single kanji input control section. As described above, only the bottom row is displayed as shown in FIG. 30, and the other rows are hidden.

That is, in the single kanji input state, the DCOT selects the data of PM2 under the control of the single kanji input control section and displays it on the CRT.

Select a desired kanji from the displayed kanji group by pressing the key corresponding to the display, and enter the kanji code into PMI.
send to

As a modified example, in the single kanji input described above, the text and the enumeration of the single kanji characters were not displayed at the same time, but by doing so as shown in FIG. 31, the operability can be improved.

-Here, if the operation of the character processing device is explained using the flowcharts shown in Figs. 33 to 60, Fig. 33 shows the main control 7o-chart, and in the figure, Y is an abbreviation for YES and N is an abbreviation for NO. be.

The main control unit is the mode key (DIN, IDK.

AMK), FIFO, print key, cursor shift key, EDIT key, ygs key, BACK -+-1
DEVICE such as INv key, NO4--1 NT key, etc.
Read the information from and select the corresponding job (JOB).
Decide and activate the corresponding control unit. Here, the mode key has a function that allows reading at any time.It also indicates whether information has been received by the other DEvTCE or not, that is, whether there is information that has not been read yet. and a function to store the information until it is read.

When there is input from the FIFO, the control section that is activated differs depending on the state of the mode key. In other words, when the AMK key is automatic, the KBI input control section is used, and when the AMK key is single kanji and the IDK key is indirect, the single kanji manual control section is used, and the AMK
When the key is a single kanji character and the IDK key is direct, activate the DIN input control section.

If there is an input from the print key, the print control unit; if there is an input from the cursor shift key, the cursor shift key control unit; if there is input from the gDIT key, the EDIT key control unit; if there is l key force, the Yl key control unit; B
If there is an input from the ACK key, the B A (:' K key control section, if there is an input from the Nv key, the INV key control section; if there is an input from the NO key, the NO key control section,
When there is an input from the NT key, each INT key control section is activated.

Figure 34 shows the four-chart of KBI input control, and the part surrounded by dotted line 101 is the control that leaves the last six characters of the kana data that has already been converted in the converted sentence buffer as necessary. It shows a routine. In this flowchart, N (I) indicates the data at address 1 of the buffer or memory N.

Also, IHBUF is a conversion statement buffer, and ILA is an I that is used to transfer the first data part of the reference range for conversion of the next input data after the data in IHBUF is converted.
The address information of HBUF, INPUT, is O in the initial state or when conversion control is completed, and is 1 during input.

IKS indicates a shift state of a kanji, α indicates a shift to a kanji, and β indicates a shift to a non-kanji. When an input is made, when "INPUT" is 0 as an initial value, that is, when input is started or immediately after kana-kanji conversion is completed, follow the flow in 101, and in the former case, the beginning of the conversion range. In the latter case, the last 6 characters of the part that has already been converted are filled from the beginning of IHBUF, that is, IHBUF(1), and then converted to the beginning of the conversion range, that is, MPA(1>). The beginning of the reference range, ie, M P A (5) is determined.

If "INPUT" is not 0 or the key input after passing through the flow in 101 above is a kanji shift code, the current state is a shift state to a non-kanji character, that is, IKS=
Check whether it is @, and if it is IKS-@, change the kanji shift code to @, and if other times, change it to @ and move to 100 or 130. The flow starting with 130 is for inputting Roman characters, and if necessary, enter p-Maji →
Kana conversion is performed.

In FIG. 34C, it is determined whether or not kana-kanji conversion should be started, and if so, the conversion range and reference range are determined. In addition, in FIG. 34B, 102 is a Stella/ that determines whether it is a hiragana or katakana, and 1

By comparing the value of McW(4) with the value of MCW(1)+MCW+21, it can be determined whether all searches for conversion units have been completed. If there is a residual portion as a result of the determination, step 19 is performed, and if there is no residual portion, the process proceeds to step 17.

17. Start up the conversion unit table creation control section and prepare to write the conversion word into the conversion word table.

18. Start the conversion processing control unit and perform writing to the PMI, writing to the conversion word table, etc.

Proceed to step 1 to check whether there is any remaining first character string that has not been converted into the converted sentence BUF.

19. Update Nl8T DEPTH.

20. Check whether NgsTDBPTH overflows or not. If it overflows, it is determined that the search is impossible and the process proceeds to step 24.

21. Check whether the word dictionary table overflows or not. If it does, proceed to step 24.

FIG. 41 is a search control 70-chart.

FIG. 42 shows the conversion unit table creation control flowchart 7, (g), where ■ is the ROW number of the conversion unit table, and the operation of each step will be explained below.

1. The search results by the conversion control unit are entered in the nest table. A compound word (namely, a converted word) consisting of a combination of words is created from this nest table, and the number of the word dictionary table is entered in the IW to 8th W of the conversion unit table. (Of course, it may not be a compound word.) 2. Write the number of combinations of 掬合藺 in M(:'W(8)).

3. Enter the number of words for the combination in the word count column of the conversion unit table.

4. Steps 4 to 24 are for determining the respective parts of speech for the converted words created in step 1.

In step 4, first, the conversion unit table's OW black is initialized to 1.

5. If MCW←, that is, it is a compound word, proceed to step 6.

If MC~vt7+=1, that is, the converted word consists of one word, the process advances to step 24.

6. If the word is a compound word consisting of two edicts, proceed to step 7.

If the word is a compound word consisting of three or more words, proceed to step 23.

7. Check the part of speech of the first edict.

8. If it is a prefix, proceed to step 2o. If it is not a prefix, proceed to step 9.

9. If it is a noun, go to step 1o; if it is a noun-c', go to step 2'3.

10. Check the part of speech of the second edict.

11. If the second part of speech is a noun, proceed to step 21.

If it is not a noun, proceed to step 13.

12. If the part of speech of the second edict is between pseudonyms, step 2
Proceed to 2.

If it is not between pseudonyms, proceed to step 13.

13. If the second part of speech is a suffix, proceed to step 14. If it is not a suffix, proceed to step 23.

14, ,15. If the character code of the second edict is "target", proceed to step 16; otherwise, proceed to step 23.

16. Enter that it is an adjective verb in the part of speech column of the conversion unit table.

17. Write down that it is a conjugation in the conjugation column.

18. 19. Steps 5 to 24 are applied to the subete conversion word entered in the conversion unit table.

20. Enter the part of speech and conjugated form of the second edict in the conversion unit table.

21. Enter that it is a noun in the part of speech column of the conversion unit table.

22. Fill in the part of speech column of the conversion unit table to indicate that it is between pseudonyms.

23. Enter 0 in the part-of-speech and conjugation columns of the conversion table.

24. Enter the part of speech and conjugation form of the original language in the part of speech column and conjugation form column of the conversion table.

25. Initialize the conversion unit table certainty to 4w4L O.

26-29 In order to set the certainty column of the conversion unit table, the grammar weight control section, frequency weight control section, connection weight control section, and field weight control section are activated.

30. Activate the threshold determination control unit to determine the threshold to be adopted as the conversion word.

31, Set MCW+91.

FIG. 43 is a threshold determination control flowchart, in which the conversion unit Q-y"i;'L is calculated by subtracting 1000 from the maximum value of the entered certainty value, and 0
The threshold is determined by using the larger value of the threshold.

Figure 44 shows the grammar weight control flowchart, and ■
indicates the LOW number (of the conversion unit table).

In this flowchart, if a character string to be referenced exists at the front of the conversion unit, a front grammar check routine is activated.

If there is a character string to be referenced at the end of the conversion unit, an unchanged kana part check routine and an inflected form check routine are activated.

The above grammar check is applied to all conversion words written in the conversion unit table.

FIG. 45 shows a front grammar checker, which increases the certainty value when the converted word is a verb and the front part of the converted unit is a case particle.

FIG. 46 is a flowchart for checking the unchanged kana part. If the number of words of the converted word is 1 and it has an unchanged kana part, it is checked whether the unchanged kana part matches the character form that follows the 1jth position of the converted unit. Find out and give a certainty value.

FIG. 47 shows an inflection check freechard. When the converted word is a verb, an adjective, or a variable amount, if the inflection is determined, the character string that follows is also limited to a few characters. Utilizing this fact, we give a certainty value for each converted word.

FIG. 48 is a frequency weight control flowchart, and ■
are the R and OW numbers of the conversion unit table. Here, when the converted word consists of one word, the frequency of the compound word is set to 2 or more words or 4. When the frequency consists of two frequencies, the sum of their frequencies is given as the certainty value.

Figure 49 shows the connection weight control friendship, and for the converted word when the number of words is 2, the connection table (1),
Based on (2), we find the strength of the bond and give certainty.

The above operation is performed for all conversion words entered in the conversion unit table.

Figure 50 is a field weight control flowchart, and ■
WD is the word dictionary table, positive is the input sentence field register (1
6W). This chart 70 shows the flow for determining the weight of each conversion word based on the contents of the input sentence field register IBR and the field information of each conversion word.

FIG. 51 is a conversion result processing flowchart, and each step will be explained below.

1. Initialize current address J to MPA (3).

2. Repeat the following operations until the current address J becomes MPA+21+1.

3. Read the contents of the current address J from the conversion statement BUF.

4. Since the read content is the kanji shift code @, proceed to step 9. If it is not @, proceed to step 5.

5. The read contents are PMI indicated by PNTI.

Move inside.

6. Increment PNTI.

7. Increment the current address J.

8. At the stage of step 8, the processed address +1 is stored in the current address J, and the value is set to M P
Set to A(3).

9. When MCW(9)=-1, that is, there is no conversion word, proceed to step IO.

MCW(9) +-1, that is, when conversion 8tI exists, it approaches snap 17.

10, ~16. The contents of the conversion sentence BUF are read and sequentially written into the page memory PMI. At that time, the current address J
and PNTl are sequentially incremented.

If the current address J reaches MPA(2)+1 on the way, the process advances to step 8. If the content that continues to appear is the kanji shift code @, proceed to step 8. Is the content that came out one after another written in letters? 7 If the unlock code is @, PM the code.
Writing to 1 is omitted.

17. If the converted word is 11kl, proceed to step 23; if there are two or more converted words, proceed to step 18.

18, MPA (4) btt 15=0, b-th 1
Write 4=0 to the PMI indicated by PNT 1.

19. Increment PMTI.

20. MC from the conversion unit table in descending order of “certainty”
Extract the number shown in W(9).

21,. The character code and field information of the converted word are found by referring to the 22-word dictionary table and written into the converted word table.

At that time, set 1DN=1.

23. Update MPA (4).

24, ~26. Conversion Single conversion - Extracts the one with the highest degree of certainty from among the converted words written in the bull, and converts the converted word into a character code by referring to the word dictionary table. After that, the character code is extracted. Write to PMI.

27. Update current address J.

28. If there is one converted word, proceed to step 29; if there are two or more converted words, proceed to step 10.

29. Find the field information that constitutes the converted word from the word dictionary table, enter it in the converted word field register, and start the field determination control section.

Note: Actually, 1 increment of PNT 1
It is necessary to limit the value so that it does not take a value of 93 or more.

FIG. 52 is a field determination control flowchart for automatically determining the field of an input sentence, where lHf3R is a conversion word field register and IBfL is an input sentence field register (16W).

FIG. 53 is a cursor shift key control flowchart, in which PNTl is cyclically incremented from 1 to 192.

FIG. 54 is an EDIT key control flowchart, in which bit 15=o from the beginning of page memory PMI.

Find a location where 6x14=1 and set that value to PNTI.

FIG. 55 is a NO key control flowchart, and this ROutiNE is valid only when the cursor is at the * mark position.

From the contents of PMI indicated by PNTI, it is possible to know the address where the conversion word information stored in the conversion word table exists. 1 iDN entered in the conversion word table
Cyclically increment in the range of ~iRN and commit the conversion word indicated by iDN to the PMI.

FIG. 56 is a BACK key control flowchart, and N
It differs from the O key control section only in the following points. That is, i.D.
The point is that N is cyclically decremented between iRN and 1.

FIG. 57 is an INV key control flowchart, and when the cursor is at the * mark position, the PMI indicated by PNTI
By checking the contents of , it is possible to know the address where the reading information (first character string) stored in the conversion word table exists. The first character string thus found is moved into PMl. In this case, since the length of the second character string is generally shorter than the length of the first character string, in order to secure a place to store the first character string in PMI, the character string that exists after the cursor in PMI is must be moved.

FIG. 58 is a YES key control flowchart, and this routine operates only when the cursor is placed on the * mark. P
The corresponding position in the conversion word table is missing from the PMI search content pointed to by NTl.

After the field information stored in the record corresponding to the iDN is stored in the field register, the field determination control section is activated.

Next, bit l of PMl information indicated by PNT l
By setting 5 to D, the x mark will disappear from the CRT display.

Next, search for the wooden mark after the cursor and move the cursor to that position.At this time, if there is no real mark after the cursor, set PNT to 1 and move the cursor to the top of the CRT display.

FIG. 59 is a print control flowchart, in which PMl
