Abstract

PURPOSE:To miniaturize a memory for a KANA (Japanese syllabary)/KANJI (Chinese character) conversion dictionary, etc. and also to improve the processing efficiency of KANA/KANJI conversion, by providing a RAM area for priority information, a RAM area for user registered word dictionary, etc. CONSTITUTION:A RAM area 25 for priority information stores the priority information groups of word readings and the KANJI words having said reading. While a RAM area 26 for user registered word dictionary stores the user registered word dictionary stores the user registered word groups. In a KANA/ KANJI conversion mode, the priority information group having the reading of the corresponding word is written on the head of the area 25 with reference to the area 25 or 26 when the KANJI words are fixed to an input KANA character string. Therefore the priority information group already stored is shifted backward. Thus a memory for KANA/KANJI conversion dictionary, etc. can be miniaturized and at the same time the processing efficiency is improved for KANA/KANJI conversion by providing both areas 25 and 26.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention has a word dictionary in ROM, priority information of homophone opposite words and user word registration dictionary in RAM, and uses these to write kana-kanji. The present invention relates to a kana-kanji conversion processing method that performs conversion processing.

[Prior art and problems]

A Japanese electronic typewriter has a keyboard that can input kana, a display unit that displays the input character string and the kanji character string that is the result of kana-kanji conversion, a printer unit that prints the created document, and the input kana character string. It is equipped with a kana-kanji conversion mechanism that converts characters into kanji strings. A conventional Japanese electronic type-like has, for example, a CRT display with a display screen of 48 characters x 22 lines, as well as a floppy disk device, a magnetic disk device, etc. for storing dictionary documents. This type of Japanese electronic typewriter has drawbacks such as being unportable and expensive, so it is desirable to realize a portable Japanese electronic typewriter.

[Purpose of the invention]

The present invention is directed to a kana-kanji conversion processing method that can reduce the size of a storage device that stores dictionary documents for kana-kanji conversion and can efficiently perform kana-kanji conversion processing. is intended to provide.

[Means for solving problems]

Therefore, the kana-kanji conversion processing method of the present invention includes a word dictionary ROM that stores a plurality of word groups each consisting of a word's reading and a word expressed in kanji having this reading; RAM area for user registered word dictionary that can store multiple user registered word groups consisting of words, and multiple priority information groups consisting of word readings and priority information of words written in kanji with these readings. In a Japanese electronic typewriter that is equipped with a RAM area for priority information that can be used to convert kana to kanji, when a word written in kanji for an input kana character string is determined, priority information with this reading is determined. The present invention is characterized in that the group is written at the beginning of the priority information RAM area, and the priority information groups already stored are shifted to the rear.

[Embodiments of the invention]

First, an overview of the Japanese electronic typewriter of the present invention will be explained.

(b) Regarding the display screen In conventional Japanese electronic typewriters, documents are created on the display screen, but the basic idea of the present invention is to keep the display screen to the minimum size necessary for kana-kanji conversion. The idea is to use the printed results on paper in place of the display screen of conventional Japanese electronic typewriters. In the embodiment of the present invention, a liquid crystal panel is used as the display section, but since the cost of the liquid crystal panel is proportional to the number of displayed characters, the number of displayed characters is made as small as possible.

The size of the display screen of the liquid crystal panel is, for example, 8 characters x 1 line. In Japanese electronic typewriters that use the kana-kanji conversion method, it is necessary to display the input kana character string and the conversion candidate kanji character string on the display screen, but since these are different from the final printed characters, the display screen It is displayed only on the screen and printed after confirmation.

(b) Regarding the ejecting method Since the display screen of the Japanese electronic typewriter of the present invention is small (for example, 8 characters x 1 line), it is necessary to eject characters one after another, and the ejected characters must be printed. There are two methods for removing characters from the display screen: one is to remove characters immediately after the conversion is confirmed, and the other is to remove characters from the keyboard manually when the cursor is past the right edge of the display screen, then move the character string on the display screen one character to the left. One possible method is to shift the characters to the left end of the display screen and display the characters input from the keyboard at the right end of the display screen.

(c) If you want to refer to the previous and subsequent parts that have already been created regarding the relationship between the cursor and the printer head, press the upward cursor movement key. Then, the character string in the same digit range of the previous line is read from the document memory and displayed on the display screen, and the printer performs a reverse change operation, and the printer head corresponds to the leftmost character on the display screen. position on the printing paper. When the downward cursor movement key is pressed, a printer change operation is performed. When the left cursor movement key is pressed while the cursor is at the left end of the display screen, the entire screen is shifted to the left and the printer head is moved to the left. When the right cursor movement key is pressed while the cursor is past the right edge of the display screen, the entire screen is shifted to the right and the printer head is moved to the right. In this way, the printer head is positioned at the position on the paper where the leftmost character on the display screen is to be printed. In the above explanation, when the screen moves up, down, left, or right, the relative position between the printer head and the paper changes. When changing from the i line to the i-1 line, the printer may perform a line feed or reverse feed operation.

(d) Regarding printing control for characters that overflow from the display screen In a method that prints characters when they overflow from the display screen, if you simply print when the characters overflow from the left edge, the previous line will be When displaying, there is no opportunity to print the characters currently displayed on the screen. Also, when the entire screen is shifted to the left and characters already printed on that line are displayed again, the characters that have not yet been printed on the screen overflow from the right edge of the screen. Printing characters that overflow from the right edge is difficult for printers that print in one direction (it also damages the ribbon). Therefore, when the printer head moves from the first line to the first line (i≠J) (when the operator moves the cursor using the up cursor movement key or down cursor movement key, or when the printer head moves from the first line to the first line (i≠J), When the head is moved to the previous line by pressing the left cursor movement key when it is at the beginning), the characters that have not yet been printed on the i-th line are printed all at once.

If you are constantly printing characters that overflow from the display screen, if you move the cursor under the state where the character string of the already printed part is displayed on the display screen and the characters overflow from the left edge of the display screen, the characters already on the paper will be printed. More characters are printed in the area where characters were printed. Also, if you want to correct text that has already been input, if you print it out, the text will be overwritten on top of the original text and will become unreadable. Therefore, printing is performed only when characters are written on blank spaces.

(e) Line boundary display Although character strings spanning lines are displayed continuously on the display screen, marks are displayed on the screen to indicate line boundaries. For example, there is a character string "Kyo wa", and "Kyo" is in the m-2 to m digit of the i-th line (the m digit is the right end of the range to make a sentence), and "ha" is in the left end of the i-th line At one point, on the display screen, ``Kyou; ha...'' is displayed.

(f) About the two calling methods If you keep pressing the left cursor movement key or the right cursor movement key, the screen will shift horizontally and each line will be displayed one after another on the display screen, but the upper When the directional cursor movement key or the downward cursor movement key is pressed, the character string in the digit range just above or below is read from the character memory and displayed on the screen.

(G) Regarding the Kana-Kanji conversion process ■ A word dictionary is stored in ROM, and priority order information of homophones and a user registered word dictionary are stored in RAM.

and R A M nJf assigned to priority information
The expulsion of priority information from the area and the expulsion of user registered words from the RAM f+i area assigned to the user registered word dictionary are performed independently.

■ Evict candidates are determined by LRU, but the latest information is added to the beginning of the area, and the last information in the area is evicted. Homophones are in one group, so if the pronunciation to be registered or to be added with first order ranking information is in the middle of the area, it is brought to the top position and new information is added there.

■ If there are too many user-registered words, show the candidates to the user and get their confirmation before expelling them.

■ Allow the priority order information of homophones and the user's registered word dictionary to be retrieved externally.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, 1 is a keyboard, 2 is an input cover sofa, 3 is a kana-kanji conversion mechanism, 4 is a conversion result holding unit, 5 is a control unit,
6 is a character number counter, 7 is a cursor position register, 8 is an effective reading length counter section, 9 is an input status flag section, 10 is a confirmed status flag, 11 is a display code buffer, 12 is a save/receiver buffer, 13 is an overflow control 14 is a character generator, 15 is a liquid crystal panel, 16 is a printer, 17 is a format memory, 18 is a document memory, 19 and 20
21 indicates an input row buffer, 21 a comparison section, 22 an address generation section, and 23 a +1 circuit. The keyboard 1 is used to input kana characters, alphanumeric characters, and the like. The manual buffer 2 temporarily stores kana character strings input manually from the keyboard 1. The character string of the input cover sofa 2 is stored in the display code buffer 11 via the control section 5. When the conversion key on the keyboard 1 is pressed, the kana-kanji conversion mechanism 3 is activated. When activated, the kana-kanji conversion mechanism 3 converts the kana character string in the input kabanofa 2 into a kanji character string, and writes this into the conversion result holding unit 4. The kanji character string in the conversion result holding unit 4 is stored in the control unit 5.
is sent to the display code buffer 11, and the corresponding kana character string in the display code buffer 11 is replaced with a kanji character string. The control unit 5 controls the entire Japanese electronic typewriter, and includes a character number counter 6, a cursor position register 7, an effective reading length counter 8, an input status flag 9, and a confirmed status flag 10. The character number counter 6 is for displaying line boundaries. The cursor position register 7 indicates the cursor position on the liquid crystal panel 15.

The effective reading length counter 8 indicates the number of kana characters in the kana character string to be converted. When the next character is input from the keyboard 1 after the conversion key is pressed, the kanji character string for the kana character string to be converted is determined. The character string in the confirmed state is stored in the document memory 18. A character code is stored in the display code buffer 11, and the content of the display code buffer 11 is converted into a character pattern by the character generator 14, and then displayed on the liquid crystal panel 15.
sent to. That is, a character pattern corresponding to the content of the display code/hesofa 11 is displayed on the liquid crystal panel 15.

The save buffer 12 is used to save the contents of the display code buffer 11.

For example, if you enter "Kyouha" from the keyboard 1 with rABcDJ written in the display code buffer 11 and the cursor pointing to rAJ, rABc
DJ is replaced with "Kyoha". When the conversion key is pressed in this state, the character "Today is D" is written into the display code buffer 11. The save buffer 12 is used, for example, to implement such a function.

When a new character is sent to the display code buffer 11 when the cursor is beyond the right edge of the liquid crystal panel 15, that is, when the value of the cursor position register 7 is "'8", the display code buffer The leftmost character of display code buffer 11 is overflowed and a new character is written to the right end of display code buffer 11. Also, the value of cursor position register 7 is “8”
If the right cursor movement key is pressed at this time, the characters at the left end of the display code buffer 11 overflow, and a blank space is written at the right end of the display code buffer 11. The overflow control unit 13 performs controls such as writing characters overflowing from the left end of the display code buffer 11 into the input line buffer 19. The format of the document is determined by the contents of Format Memo January 7. In order to manage the document memo January 8, a display start position register is provided. This display start position register indicates the document memory address corresponding to the leftmost digit of the display code buffer 11. Every time the upward cursor movement code corresponding to the upward cursor movement key is input, the contents of the display start position register are incremented by -n (where n is the number of digits in one line), and the downward cursor movement code is input manually. The above contents are incremented by +n each time. If the leftward cursor movement code is input when the content of the cursor position register 7 is "0", the content of the display start position register will be -
1 will be given. If the rightward cursor movement code is input when the content of the cursor position register 7 is "8", the content of the display head position register is incremented by 1.

The leftmost digit of the display code buffer 11 is from the i-th line to the j-th digit.
When the line changes, the printer 16 prints the characters that have not yet been printed out of the character string in the i-th line of the document memory ratio. The printer 16 is, for example, a thermal printer. After this process is completed, the line feed or reverse feed operation of the printer 16 is performed, and the printer 16's end is positioned at the jth line, and the characters on the jth line of the document memo January 8 are placed in the input line bar. Written to Nofa 20. When the character in the X digit of the jth row overflows from the left end of the display code 11, this character is stored in the X digit of the input line buffer 19, and this character is compared with the character in the X digit of the input line buffer 20. 21, and if the character in the X digit of the input row buffer 20 is blank, the display code buffer 1
The character in the j-th row, X-th column that overflows from 1 is printed on the j-th row, X-th column by the printer 16. When the position in the document memory corresponding to the leftmost digit of the display code buffer 11 changes from the jth line to the jth line, the jth position of the document memo January 8
The printer 16 must print the characters in the string of rows that have not yet been printed. For this reason, the following processing is performed.

Character string aI+aZ stored in input line buffer 19
+"'an and the character strings s, , b2.-b7 stored in the input line buffer 20 are compared.b.

If (i=1.2-n) is blank, change s to ai,
If it is not a blank but a regular character, leave it as is. The resulting string is CI + cz + '-'
Let it be cn. Currently, the character string in the jth line of the document memory 18 is
,,d2. −d, . Character string d,,d2. -d
, and the character string c, + 02 +-C11. , C8 is blank, leave d, and if d8 is not a blank but a regular character, remove d.

Let the character string obtained as a result be e, + C2+ -en. The printer 16 may print each character of this character string e l'+e 21-e 6 at the corresponding column position of the j-th row. The address generator 22 determines the address when accessing the document memory 18, and the +1 circuit 23 increments this address by +1.

Note that the actual hardware for implementing the present invention is as follows:
The format memory 17 and the document memory 18 are composed of RAM, the character generator 14 is composed of ROM,
The parts other than this RAM, keyboard 1, liquid crystal panel 15, and printer 16 are program memory, dictionary memory,
It consists of a microprocessor and other memory areas.

FIG. 2 is a diagram for explaining the word dictionary, priority information, and user registered word dictionary used in the kana-kanji conversion process of the present invention. In Figure 2, 24 is a ROM, °2
5 is RA allocated to store priority information
The MjI area 26 indicates the R A M 'w4 area allocated for storing user registered words. The ROM 24 stores a plurality of word groups each consisting of a word's reading and a word written in kanji having this reading. As shown in the diagram, words written in kanji that have the reading ``kiko'' include ``climate,'' ``port call,''``contribution,'' and ``stomata,'' but these constitute one word group. .

A plurality of priority order information groups are stored in the RAM area 25, each consisting of word pronunciations and priority order information of words written in kanji having these pronunciations. The priority information group shown in Figure 2 is composed of the character string 3.2, which indicates that the priorities are ``1 contribution'', ``port call'', ``climate'', and ``stomata''. Note that the numbers such as 3'' and a2'' in the priority information group indicate the order numbers of the words written in kanji and stored in the word group with the reading "Kiko".

A plurality of foam user registered word groups are stored in the RAM area 26, including the pronunciations of words and words written in kanji having these pronunciations. In the illustrated example, the user-registered words that have the pronunciation "Kikou" are "Maegyo" and "Kikyou." Note that the size of the RAM area 25 is fixed, and the size of the RAM area 25 is fixed.
The size of area 26 is also fixed. FIG. 3 shows an example of the contents of the priority group including the contents of the user registration dictionary.

In this example, the priorities are "Contribution", "Previous School", "Climate"
, "Your Honor," and "Port Call."

Assume that the kana character string "Kikou" is input and the conversion key is pressed. Then, the RAMv4 area 25 is first searched to see if there is a priority information group with the pronunciation "Kikou".

If there is no priority information group with the pronunciation "Kikou" in the RAM area 25, the RAM area j
lU26 is searched. Since there is a user registered word group with the pronunciation "Kikou" in the RAM area 26, the first word "Maegoshi" is read out and the LCD panel 1
When the conversion key 6 displayed at 5 is pressed again, "Kiryou" is read out from the RAM file area 2 and outside 6 and displayed on the liquid crystal panel 15. When the next character is entered while "Kikou" is displayed, the word written in kanji for "Kikou j" is confirmed. Once confirmed, “Let’s go”
In the user registered word group with the reading ``Kikyou''

is written at the beginning of. At this time, the priority information group already written in the RAM area 25 is "Kikou".
It is shifted to follow the priority information group with the reading. At this time, if there is not enough space, the last one will be kicked out. If the conversion key is pressed while "Mrs." is displayed, the ROM24 will be changed to "
It is searched using the key "Kikō". And ROM2
"Climate" is read out from 4 and displayed on the liquid crystal panel 15. When the conversion key is pressed while "Climate" is displayed, "Port of call J" is read from the ROM 24,
It is displayed on the liquid crystal panel 15. When the following characters are entered while "Port Call" is displayed, "Kikou 2" is displayed.
A priority information group with the contents is written at the beginning of the RAM area 25, and the priority information group already stored is shifted backward.

If a priority information group with the pronunciation "Kikou" exists, this priority information group is read out. The priority information group with the pronunciation "Kikō" is Kikō 3. Assuming that u, 1, "contribution" is read from the ROM 24 and displayed on the liquid crystal panel 15. If the following characters are input while "Contribution" is being displayed, a priority information group called "Kikou 3.u, IJ" will be written to the beginning of the RAM N area 25, and if the priority information group is already stored. If the conversion key is pressed while "Contribution" is displayed, "Previous School" is read out from the RAM 顯@26, and the priority information group is shifted backward. will be displayed. Assuming that the "previous school" is confirmed, the priority information group "Kiko u, 3.IJ" is written to the RAM fJ area 25 as described above. When the conversion key is pressed, "r climate" is read out from the ROM 24 and displayed on the liquid crystal panel 15. Once the “climate” is determined, [Kikou 1, 3. The priority information group 'uJ is written into the RAM area 25 as described above. When the conversion key is pressed while "Climate" is being displayed, "Kiki" is read out from the RAM1Jf area 26 and displayed. Assuming that "Kikou" is confirmed, the contents of the user registration word group "Kigou" will be "Kikou".
The priority information group ``Kiko u, 3.u, IJ'' is stored in the RAM area 25 as described above. When is pressed, "Port call" is sent from ROM24.
