Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dictionary device suitable for converting an input character string and a text input device using the same, and is particularly suitable for a device having a limited number of keys, such as a portable information terminal. The present invention relates to a text input device.

Conventionally, various text input devices have been realized by portable information terminals such as portable wireless telephones.
First, as shown in FIG. 39, it is known to use a numeric keypad (dial key) 203 arranged in 4 rows and 3 columns from the central portion of the surface of a handset 201 of a portable wireless telephone to the lower side. The following two input methods are known.

The first method uses a matrix character arrangement table as shown in FIG. That is, a pair of numbers and one character (symbol) are stored in association with each other. Then, referring to the above table, one character (symbol) can be input by inputting a pair of numbers corresponding to a matrix of desired characters (symbols). For example,
When it is desired to obtain an input of "Toukiyou (Tokyo)", as shown in FIG. 41, the user operates "4513228513" and the ten keys. As a result, "Toukiyou" is displayed on the display unit 202 of the mobile wireless phone shown in FIG. 39 in correspondence with the pair of numbers.

In the second method, a numeric code and a fixed phrase are stored in association with each other, and a code corresponding to a desired fixed phrase is input by operating the ten-key 203 with reference to the code table of the fixed phrase. To do. For example, it is assumed that a character code string of a fixed sentence is stored corresponding to a two-digit code as shown in FIG. In this case, if the user wants to input "call the company", he / she operates the ten keys 203 to input "01". As a result, "Call the company" is displayed on the display unit 202 of the mobile wireless phone in FIG. 39 corresponding to the entered code.

[0005]

However, according to the above-mentioned text input device, basically, there is a problem that key input cannot be performed without a conversion table, which is inconvenient. On the other hand, as shown in FIG.
There is also known a mobile radio telephone or the like in which a plurality of kana characters are assigned to each of the three. In this device, the number of operations of each key and the character are stored in association with each other. When the number of operations on each key is 1, the leftmost character of the corresponding notation is input, and when the number of operations is increased by 1, the characters shifted to the right by 1 are input. For example, to obtain an input of "Toukiyou (Tokyo)", as shown in FIG.
411122888111 ”and the numeric keypad 203 are operated. As a result, the display unit 20 of the portable wireless telephone shown in FIG.
In "2", "Toukiyou" is displayed according to the number of key operations.

According to this text input device, the conversion table is unnecessary as described above, but the number of key operations becomes extremely large,
In some cases, there is a problem in that the number of operations is erroneously counted and an erroneous input is made. In addition, it is also performed, for example, in a selective call receiver or the like to input numbers side by side by matching words. That is, as shown in FIG. 45, each message “Hayakukoi”, “Sorry”, “Good morning”, “Congratulations”, etc., has a number string “888951”, “5731”, “0840”, which is a vocabulary.
Corresponding to "0010", this numeric string is entered with the ten keys, and the entered numeric string itself is transmitted to the partner terminal and displayed. However, this device has a problem in that it is generally inconvenient to use because it is premised on knowing a numeric matching numeric string and a message relating to its content. In addition, there are some messages that cannot be expressed simply by using vocabulary, making it difficult to accurately convey the intention to the other party.

The present invention has been made in view of the problems of the conventional text input device as described above, and an object of the present invention is that a conversion table is unnecessary and the number of key operations is not increased. Another object of the present invention is to provide a text input device using the above-mentioned dictionary device.

The structure of the keyboard 11 is shown in FIG. A key matrix 10 is provided corresponding to each key of the ten-key pad 103, and one contact of each switch of the key matrix 10 has a pull-up resistor and a row (row).
) A voltage of 5V is constantly applied via the direction lines Out0 to Out3, and the end points of the row direction lines Out0 to Out3 reach the input control unit 12. Also, the key matrix 10
Column-direction lines M0 to M2 are connected to the other contacts of the switches, and the end points of the column-direction lines M0 to M2 reach the input control unit 12.

On the other hand, the input control unit 12 is constructed as shown in FIG. The input control unit 12 includes a control unit 20 that performs overall control, a timer 21, a memory table 22, a memory (MEM2) 23, a memory (MEM1) 24, a latch 25,
And 26. The latch 25 is a circuit that latches drive signals for the column direction lines M0 to M2 sent from the control unit 20, and the latch 26 is a circuit that takes in and latches the signals of the row direction lines Out0 to Out3. The timer 21 is a timer for notifying the control unit 20 of a predetermined time interval (1 mS) in order to doubly read the key operation in order to eliminate chattering that occurs during key operation. The drive signal output to the latch 25 is set in the memory 23, and the detection signal held in the latch 26 at that time is set in the memory 24. The memory table 22 stores data for specifying the operated key, and its contents are as shown in FIG. That is, the data set in the memory 23 is
When the set values of MEM2 in FIG. 6 are “0”, “1”, and “2”, the three patterns arranged in the lower three columns of MEM2 in the lateral direction correspond to the lower columns and are set in the latch 25. Indicates that it has been done. Therefore, when any of the three patterns arranged in the lateral direction in the lower three columns of MEM2 is set in the latch 25, the set values "0", "1" in MEM2 of FIG. Any one of the numbers “2” is set, while the latch 26 is set to one of the four patterns arranged in the lower row lateral direction of MEM1 in FIG.
This value is set in the memory 24. Therefore, in FIG.
The number at the intersection of any of the four patterns in the lateral direction of MEM1 and any of the set values “0”, “1”, and “2” of MEM2 indicates the number of the operated key. For example,
“1” is set in the memory 23, and “10” is set in the memory 24.
When "11" is set, a code indicating the "5" key is output from the memory table 22. At this time, it indicates that “101” is set in the latch 25.

Since the control unit 20 performs key reading by the program of the flowchart shown in FIG. 7, the operation of the control unit 20 will be described according to this flowchart.
First, the latch 25 is made to latch a signal so as to output "0" to all of the column direction lines M0 to M2 (S1), and the latch 26 latches that "0" appears in any of the row direction lines Out0 to Out3. Monitoring is performed based on the signal (S2).
When "0" appears, refer to the timer 21 and wait for 1 ms (S
3) The signals of the row-direction lines Out0 to Out3 are fetched from the latch 26 and set in the memory 24 (S4). further,
The timer 21 is referred to wait for 1 mS (S5), the signals of the row-direction lines Out0 to Out3 are fetched from the latch 26, and it is detected whether the contents are equal to those already set in the memory 24 (S6). Here, when they are not equal, the operation is continued by returning to step S2 again, while when the reading results of the first and second times are equal, a signal is output to the latch 25 to output "0" only to the column direction line M0. "110 (=
M2M1M0) "is set," 0 "is set in the memory 23 (S7), and" 0 "is set to one of the signals of the row direction lines Out0 to Out3 latched by the latch 26.
It is detected whether there is any (S8). That is, when "0" is output only to the column direction line M0 and one of the four keys connected to the column direction line M0 in FIG. 4 is operated, the signals of the row direction lines Out0 to Out3 are output. "0" appears in any of the above. Here, the row direction line Out0 ~
If there is no "0" in any of the signals of Out3, the signal "101" is latched in the latch 25 to output "0" only to the column direction line M1 and "1" is set in the memory 23 ( S9), it is detected whether any of the signals of the row-direction lines Out0 to Out3 latched by the latch 26 has "0" (S10). That is, when "0" is output only to the column direction line M1, if any of the four keys connected to the column direction line M1 in FIG. 4 is operated, the signals of the row direction lines Out0 to Out3 are output. "0" appears in any of the above. Furthermore, here, the row direction line
If none of the signals Out0 to Out3 have "0", the latch 25 latches the signal "011" so that "0" is output only to the column direction line M2, and "2" is set in the memory 23. (S11), "0" is applied to any of the signals on the row-direction lines Out0 to Out3 latched by the latch 26.
It is detected whether there is any (S12). That is, when "0" is output only to the column direction line M2 and one of the four keys connected to the column direction line M2 of FIG. 4 is operated, the signals of the row direction lines Out0 to Out3 are output. "0" appears in any of the above.

As a result of the above processing, if "0" does not appear in any of the signals on the row-direction lines Out0 to Out3 in any case, the operation returns to step S1 and the operation is continued. When "0" appears in any of the signals on the row-direction lines Out0 to Out3 in either S10 or S12, the signals on the row-direction lines Out0 to Out3 are fetched from the latch 26 and set in the memory 24 (S13). ). next,
The control unit 20 instructs the memory table 22 to output, and as a result, the memory table 22 is searched based on the signals set in the memories 23 and 24 (S14), and the key code output from the memory table 22 is centralized. Control unit 13
Send to. Next, in order to output "1" to all of the column direction lines M0 to M2, the latch 25 is made to latch the signal (S
15), it is detected whether or not all of the row-direction lines Out0 to Out3 have become "1" (restored) (S16), and if all "1" is obtained, the timer 21 is referred to after the detection and 1 mS elapses. After that (S17), it is detected whether all of the row-direction lines Out0 to Out3 have become "1" (restored) (S1).
8) If all "1" s are obtained, the process returns to step S1 to continue the operation. As described above, the numeric keypad 10
A code indicating which key of 3 is operated is sent to the central control unit 13.

FIG. 8 shows the display control unit 1 of the text input device.
7 is shown in detail. The display control unit 17 includes a character font memory 31 in which character fonts (character patterns) are stored, a character font expansion unit 32 that expands the fonts in the character font memory 31 into the image memory 33 under the control of the central control unit 13, (LCD ) Display device 16
An image (bitmap) memory 33 for holding the image data to be displayed in the form of a bit map and a character position memory 34 for storing the display font data (character code) being displayed together with the display position.

The display control unit 17 includes a central control unit 13
The display font data, the display position data, the development start instruction signal, and the position data (address) of the character position memory 34 are given from the. That is, the display font data is sent together with the expansion start instruction signal, so that the character font expansion unit 32 accesses the character font memory 31 and extracts the display font corresponding to the given display font data, and extracts the expansion position data (image). It is stored in the corresponding position of the image memory 33 based on the coordinates of the memory 33). As a result, since the data position of the image memory 33 is associated with the pixel of the screen of the LCD display device 16 on a one-to-one basis, the pixel data of the display font expanded at the corresponding position is stored. On the other hand, in the character position memory 34,
The display font data and the display position data are stored in the position of the position data sent from the central control unit 13.
The central control unit 13 can read this using a read signal, read the data (display font data) being displayed together with its display position, and through the call control unit 6, the transmitting / receiving unit 3 and the antenna 5 of FIG. Processing such as transmission to another terminal can be performed.

FIG. 9 shows the dictionary search unit 1 of the text input device.
5 is shown in detail. The dictionary search unit 15 controls the entire dictionary search unit 15 as a whole, a character input buffer 41 for storing codes of characters and character strings key-inputted, and a code pointer used for dictionary search of the word dictionary 14. 42 and a search result character output buffer 43 for holding a code of a candidate character or a character string obtained as a result of the dictionary search.

FIG. 10 shows the contents stored in the word dictionary 14 which is the dictionary device 310. That is,
Corresponding to the numerical code by operating the numeric keypad 103,
Character information or character strings in kana, characters or character strings in kanji, and attribute information such as part-of-speech, place, time, and other information are stored in association with each other.
More specifically, the structure of the word dictionary 14 is shown in FIGS.
3 is configured as shown. First, the word dictionary 14
Is composed of blocks divided into units of the number of characters, as shown in FIG. As shown in FIG. 12, the block corresponding to each number of characters is composed of a plurality of branches corresponding to the numeral string of the number of characters. Here, there are a plurality of branches corresponding to a numeric string of 5 characters in a block having a number of 5 characters, and the branch corresponding to the numeric string “41281” among them is explicitly shown. Further, FIG. 13 shows the inside of the branch corresponding to the number string “41281”. A table corresponding to the subsequent numbers (0) to (9) when present in the branch (thus, if the subsequent numbers are only (1) and (8), two tables)
And a table corresponding to the code SOS (00) indicating the beginning of the candidate corresponding to the number string when there is no subsequent number. The table corresponding to the subsequent numbers (0) to (9) includes the corresponding subsequent number and the pointer N of the next table.
TP and the pointer NBP of the next branch are set. On the other hand, when there is no subsequent numeral in the table corresponding to the code SOS (00) (that is, the numeral string “412
Code SOS (0 corresponding to "81") indicating the beginning of the candidate
0), a character or character string code Str1 to Strn, a candidate character or a code EOS (F indicating the end of the candidate character string code
F), the code EOB (FF) indicating the end of the branch is set.

As described above, the reason why a plurality of candidate characters or candidate character strings exist in one branch is not only due to the presence of homonyms as in a normal Japanese word processor, but also in one key. This is because multiple kana characters have been assigned. For example, if the "1" key and the "2" key are operated in succession, since the character strings of the "a" line and the "ka" line are input, "red" and "autumn" are entered. , “Ike”, “oke”, etc. are present as candidate character strings. In the case of the numeral string “41281” illustrated in FIG. 13, “Tokyo” and “offer” are provided.
And so on. As you can see in the above example,
The voiced sound candidates, the semi-voiced sound candidates, etc. are replaced with the pure sounds to create a dictionary.

The control unit 4 of the dictionary retrieval unit 15 shown in FIG.
0 performs the search process of the word dictionary 14 by the program of the flowchart shown in FIG. 14, so the operation of the control unit 40 will be described according to this flowchart. The control unit 40 clears the character input buffer 41 (S21), and the code of the input character or the input character string (code of the numeric key)
Waits for arrival (S22). In this example, the operator sets “Tokyo” as the input character as shown in ST1 of FIG. Therefore, the operator uses the numeric keypad 1 of the portable wireless telephone.
The corresponding key of 03 will be operated. Unlike the numeric keypad 103 shown in FIG. 1, the numeric keypad 103 shown in FIG.
Kana characters are written on the key top itself with four rounded corners, and the kana characters are katakana instead of hiragana. This character input device is a numeric keypad 1 of the embodiment shown in FIG.
No. 03, the numeric keypad 103 in FIG. 15 indicates that appropriate input is possible. Numeric keypad 103
The numeric key of "412" is displayed as shown in ST2 of FIG.
81 ”is operated. The operator is ST2 “41281”
It indicates that, among the kana characters corresponding to, a kana character surrounded by a frame is desired and input.

Then, by the operation of the input control unit 12 described with reference to FIG. 7, a code corresponding to the numeric key for the operation is obtained, and the code string corresponding to the above "41281" is stored in the character input buffer 41. Next, as shown in ST3 of FIG. 15, the operator operates the “*” key, which is the conversion / next candidate key, for conversion. The "*" key is also converted into a code by the operation of the input control unit 12 described in FIG. 7 and sent to the central control unit 13. Receiving this, the central control unit 13 sends a search start signal to the control unit 40 of FIG. Therefore, as shown in FIG. 14, the control unit 40, which was monitoring whether or not the search has started (S23), resets the code pointer 42 (S2).
4), the data selector signal is set (S2)
5). Next, the control unit 40 takes out the code stored in the character input buffer 41 from the beginning, and the word dictionary 14
The search is started from the block with 1 character. Since the search method is the same for any number, the search in the block having the number of characters of 3 will be described here.

FIG. 16 shows the processing from the search in the block having the number of characters of 3. According to the number string “412”, the table of the address “3F0F” of the block having the number of characters of 3 is reached. The subsequent number in this table is "1", and the number string "4" stored in the character input buffer 41 is
Since it is different from the fourth digit "8" of "1281", N
The next table is searched based on TP. Here, a candidate in which the number following the number string "412" is "1" and "8"
Since there are only candidates that are, the table with the subsequent number “8” can be searched immediately. Normally, the table with the subsequent number "1" is next to the table with the subsequent number "2", and the table with the subsequent number is "3" ...
In this way, the subsequent number reaches the table of "8".

If the subsequent numbers match, the N in this table
Based on the BP, we arrive at the first table of the branch "4128" with 4 characters. In this table, the subsequent number is "1", which matches the fifth number "1" of the number string "41281" stored in the character input buffer 41. When the subsequent numbers match, the table of the next branch “41281” is reached based on the NBP of this table. Originally, since there is no subsequent number stored in the character input buffer 41, "00" is displayed in the subsequent number area.
Search the table where is set. In the example of FIG. 16, the number string “41281” is also in the word dictionary 14.
It is premised that there is no candidate with a number following, that is, there is no table. Immediately from the table of branch "4128", reach the table of address "98AC" where "00" is set in the area of the subsequent number. ing.

In the example of FIG. 16, "Tokyo" is set in the first candidate character string, and the code "Tokyo" is read in correspondence with the output value "0" of the code pointer 42. The above processing corresponds to the processing of the loop from "search" in step S25 to steps S26, S27, and S28 in FIG. The stepping of the code pointer 42 in step 27 corresponds to the case of sequentially searching the table in FIG. 16 and also to the case of designating and reading each candidate character in the target table. Therefore, actually, the search for the candidate characters performed in FIG. 16 is equivalent to the case where the word dictionary 14 shown in FIG. 10 is searched. In this example, "Tokyo"
However, if the candidate character corresponding to the input number string is not stored in the word dictionary 14, the NEXT signal is given to the code pointer 42 to advance the value (S27), and the step When the candidate character or the candidate character string cannot be finally detected by repeating the loop from S28 to step S26, YES in step S28.
Branch to. That is, the END signal is returned from the code pointer 42. Therefore, the control unit 40 sends "not applicable" to the central control unit 13 according to the search result information. The central control unit 13 receiving "not applicable" sends the character font of "not applicable" to the display control unit 17 and causes the LCD display device 16 to display that there is no applicable candidate (S29).

The "Tokyo" code obtained as described above is output to the retrieval result character output buffer 43 (S3).
0). The result output notification is given to the central control unit 13 by the search result information, the code "Tokyo" is fetched from the search result character output buffer 43 to the central control unit 13, and further sent to the display control unit 17, as shown in FIG. As described, it is provided for display on the (LCD) display device 16.
That is, “Tokyo” is displayed on the (LCD) display device 16. The control unit 40 of the dictionary search unit 15 monitors the operation of the enter key or the operation of the next candidate key (S31, S3).
2). The operation of the enter key or the operation of the next candidate key is sent from the input control unit 12 to the central control unit 13 in the same manner as the operation of the conversion key described above.

In the example of FIG. 15, since "Tokyo" is the desired character, the enter key is operated as shown in ST4. The central control unit 13 obtains the code of the confirmation key and makes the search start signal inactive. In response to this, the control unit 40 of the dictionary search unit 15 proceeds from step 31 to Y.
It branches to ES and fixes the candidate character. In addition, when the candidate character strings “Tokyo” and “Tokyo” are sequentially stored in the word dictionary 14 in correspondence with “41281”,
As indicated by the parentheses in ST5 of FIG. 15, first, the next candidate key is operated in response to the display of "Tokyo", whereby the NEXT signal is given to the code pointer 42 and the value is incremented (S27). , The code of the next candidate “Tokyo” is obtained, and the process proceeds from step S26 to S30. Also in this case,
Since "Tokyo" is the desired character, the enter key is operated as shown in ST4. Subsequent processing will be performed in the same manner as described above.

As described above, since the text input device using the dictionary device according to the first embodiment has a plurality of kana character keys assigned to each key and includes the conversion / next candidate key and the enter key, A candidate character string composed of a candidate character corresponding to the kana character assigned to the operated key or a combination of kana character strings assigned to the operated keys can be appropriately input and selected. That is, it is suitable for an information terminal having a small number of keys.

The text input device according to the embodiment of the present invention displays the cursor C as shown in FIG. 17 and corrects the input characters, and also moves the cursor movement keys 61 and 62 on the keyboard 11 and erases it. A key 63 is provided. Here, since the character display for one line is performed, the cursor movement keys 61, 62 are composed of a pair of left and right keys. However, in the case of adopting a configuration for displaying the character of two or more lines, In addition to this, a pair of vertical cursor movement keys is provided. The operation information of the cursor movement keys 61 and 62 is also detected by the input control unit 12 and is sent to the display control unit 17 via the central control unit 13 like the operation information of the other keys described with reference to FIGS. 4 to 7. Given.

Regarding the cursor display, the display controller 17
Based on the cursor pointer, the cursor C is moved to and displayed in the lower line of the character display area in units of one character display area. Then, the display control unit 17 controls the cursor pointer by the program shown in the flowchart of FIG. 18 based on the input of characters and the operation information of the cursor movement key. That is, the arrival of the character code is detected (S41), and when the character code arrives, the cursor pointer is advanced one step (S42). As a result, the cursor C moves forward by one character. If the character code does not arrive, it is detected whether the cursor movement has occurred by the arrival of the operation information of the cursor movement key (S4).
3) If the operation information has not arrived, the process returns to step S41 to continue the monitoring, and when the cursor moves, the cursor pointer is increased or decreased according to the moving direction (S44). As a result, the cursor C moves forward or backward in character units. To correct the erroneously input character, the cursor C is moved to the character position to be corrected by the cursor movement keys 61 and 62, and the erase key 63 is operated to erase it, and the correct character is input. In this case, in the first embodiment, the display is performed only after the conversion / next candidate key is operated, but the abnormality after the LCD display device 16 displays that there is no corresponding candidate in step S29. In the process, the input number or the input number string is displayed, and the correction is guaranteed here. That is, in the abnormal processing, the character string input buffer 4
The numeral string set to 1 is sent to the display controller 17. When the conversion / next candidate key is operated after the correction, FIG.
The processing after step S23 in the flowchart of FIG.

FIG. 19 shows a dictionary device 310A according to the second embodiment of the present invention. This dictionary device 310A
A candidate character or candidate character string of kana characters and a candidate character or candidate character string including kanji are stored corresponding to the numeral code or numeral code string input from the ten-key pad 103. Further, this dictionary device 310A includes a number string dictionary in which candidate character strings are written by matching the numbers with each other, corresponding to the number codes or number code strings input from the ten keys 103.

FIG. 20 shows the practical configuration of the above-mentioned number string dictionary.
It is shown in FIG. That is, the number string dictionary is composed of blocks divided by the number of characters. As shown in FIG. 20, the block corresponding to each number of characters is composed of a plurality of branches corresponding to the number string of the number of characters. Here, a plurality of branches corresponding to a numeric string of 5 characters exist in a block of 5 characters, and the numeric string “6
The branch corresponding to "8221" is clearly shown. Further, FIG. 21 shows the inside of the branch corresponding to the number string “68221”. In the branch, a table corresponding to the subsequent digits (0) to (9) when present (thus, two tables when the subsequent digits are only (1) and (8)), and the subsequent digits And the table corresponding to the code SOS (00) indicating the beginning of the candidate corresponding to the number string in the case where there is no. In the tables corresponding to the subsequent numbers (0) to (9), the corresponding subsequent numbers, the pointer NTP of the next table, and the pointer N of the next branch are included.
BP is set. On the other hand, the code SOS (0
In the table corresponding to (0), there is no subsequent number (that is, corresponding to the number string "68221"), the code SOS (00) indicating the beginning of the candidate, the word matching number string code, the candidate character or the candidate character string code. Code EOS (FF) indicating the end of the branch, code EOB indicating the end of the branch
(FF) is set.

In FIG. 22, from the block of the number of characters 3 which is performed when the numeral string “68221” corresponding to “early come” is input in the case where the number dictionary of FIGS. 20 and 21 is adopted. Is shown.
Even in the sentence input device including the dictionary device 310A according to the second embodiment, the dictionary is searched by the program corresponding to the flowchart shown in FIG. Therefore, the number string “6221” with the number of characters of 3 is “6221”.
82 ", the table of the address" **** "of the block having the number of characters of 3 is reached as shown in FIG. The subsequent number in this table is "1", which is different from the fourth number "2" in the number string "68221" stored in the character input buffer 41, so the next table is searched based on NTP. Here, after the table in which the number following the number string “682” is “1”, the subsequent number is “2”.
Since there is a table that is, the subsequent number is "2"
You can search the table.

When the subsequent numbers match, N in this table
Based on the BP, the table of the address "####" of the branch "6822" having the number of characters 4 is reached. In this table, the subsequent number is "1", which matches the fifth number "1" of the number string "68221" stored in the character input buffer 41. If the subsequent numbers match, the branch "68221" with the number of characters of 5 is based on the NBP of this table.
To the table at the address "$$$$". Here, originally, since there is no subsequent numeral stored in the character input buffer 41, a table having "00" set in the area of the subsequent numeral is searched. In the example of FIG. 22, it is premised that there is no table having numbers following the number string "68221" in the number string dictionary, and the branch "68" is used.
Immediately from the table of "221", the table in which the area of the subsequent numeral is set to "00" is reached. In this example, the code of the word matching numeral “888951” is set in the table in which “00” is set in the above area, and the code is read corresponding to the output value of the code pointer 42. Subsequent processing is the first
Processing similar to that in the above embodiment is performed.

In the above embodiment, the number string "68221" is input and the number string dictionary is searched first. However, the number string dictionary is actually searched according to the rank of the candidates. In other words, the number string dictionary is not an independent dictionary,
Candidate number string "88895" is input number string "68221"
It is stored together with the candidate character strings corresponding to, such as "Hayakukoi" and "Hayakoi". Of course, the order of the candidate character strings is changed appropriately. Further, it is also possible to register only candidates for word matching numbers in the dictionary device and use them as terminals corresponding to the selective call receiver.

23 and 24 show dictionary devices 310B and 310C according to the third embodiment of the present invention. In the third embodiment, character strings having the same meaning are grouped into one group, and one word combination numeral string is assigned to this one group. Therefore, the dictionary device 310B is configured as a dictionary for searching a group number from a character string,
The dictionary device 310C is configured as a number string dictionary for searching a word combination number string from a group number. That is, since the dictionary device 310B has the same meanings for "early come", "early come", "coming soon", "immediate come", etc., these are group A, and the dictionary device 310B Input the number string "68221", "68"
Group numbers are stored in "224", "3221", and "328121" in association with the kana character string and the mixed kanji character string. In the dictionary device 310C, a group number and a numerical string by word matching are stored in association with each other. Therefore, even when any of the character strings “early come”, “early come”, “coming soon”, and “urgently come” is input, it is possible to search the numerical string “888951” by word matching.

The practical configuration of the dictionary device 310B is shown in FIGS. That is, the dictionary device 310B
Is composed of blocks divided by the number of characters. As shown in FIG. 25, the block corresponding to each number of characters is composed of a plurality of branches corresponding to the numerical string of the number of characters. Here, in a block with 5 characters, 5
There are a plurality of branches corresponding to the numerical string of characters, and the branch corresponding to the numerical string "68221" among them is clearly shown. Further, FIG. 26 shows the inside of the branch corresponding to the number string “68221”. In the branch, a table corresponding to the subsequent digits (0) to (9) when present (thus, two tables when the subsequent digits are only (1) and (8)), and the subsequent digits If there is no, the code SOS (0
0) and the corresponding table. In the table corresponding to the subsequent numbers (0) to (9), the corresponding subsequent numbers, the pointer NTP of the next table, and the pointer NBP of the next branch are set. On the other hand, the code S
In the table corresponding to OS (00), there is no subsequent number (that is, corresponding to the number string “68221”), the code SOS (00) indicating the beginning of the candidate, the group number,
Code E indicating the end of the candidate character or candidate character string code
OS (FF), code EOB (FF) indicating the end of branch
Is set.

In FIG. 27, when the dictionary device 310B shown in FIGS. 25 and 26 is adopted, the block of the number of characters 3 which is performed when the numeral string “68221” corresponding to “coming soon” is input. The search process from is shown. Incidentally, the dictionary device 310 according to the third embodiment.
Also in the text input device including B and 310C, FIG.
The dictionary is searched by the program corresponding to the flowchart shown in FIG. Therefore, in accordance with the number string “682” of 3 characters in the number string “68221”, the table of the address “****” of the block of 3 characters is reached as shown in FIG. The subsequent number in this table is “1”, and the number string “6” stored in the character input buffer 41 is stored.
8221 ”is different from the fourth number“ 2 ”, so N
The next table is searched based on TP. Here, since the table whose subsequent number is "2" exists after the table whose number following the number string "682" is "1", a table whose subsequent number is "2" can be searched. ing.

If the subsequent numbers match, the N in this table
Based on the BP, the table of the address "####" of the branch "6822" having the number of characters 4 is reached. In this table, the subsequent number is "1", which matches the fifth number "1" of the number string "68221" stored in the character input buffer 41. If the subsequent numbers match, the branch "68221" with the number of characters of 5 is based on the NBP of this table.
To the table at the address "$$$$". Here, originally, since there is no subsequent numeral stored in the character input buffer 41, a table having "00" set in the area of the subsequent numeral is searched. In the example of FIG. 27, it is premised that there is no table having a number following the number string “68221” in the number string dictionary, and the branch “68” is used.
Immediately from the table of "221", the table in which the area of the subsequent numeral is set to "00" is reached. In this example, the group number A corresponding to the word matching number "888951" is set in the table in which "00" is set in the area, and the group number A corresponds to the output value of the code pointer 42. Read out.

When the group number A is obtained, the dictionary device 310C, which is a numeral string dictionary, is searched using the group number A, and the word matching numeral string "888951" is obtained.
In the above embodiment, the number string “68221” is input and the group number is searched first.
Actually, the dictionary is searched according to the rank of the candidates. That is,
The dictionary for obtaining the group number is not an independent dictionary, but the group number A is stored together with the candidate character strings “Hayakukoi”, “Hachicomi”, etc. corresponding to the input numeral string “68221”. Of course, the order of the candidate character strings is changed appropriately. Further, it is also possible to register only candidates for word matching numbers in the dictionary device and use them as terminals corresponding to the selective call receiver.

FIG. 28 shows a dictionary device 310D according to the fourth embodiment of the present invention. This dictionary device 310D
A candidate character or candidate character string of kana characters and a candidate character or candidate character string including kanji are stored corresponding to the numeral code or numeral code string input from the ten-key pad 103. The dictionary device 310 according to the fourth embodiment.
D has a dictionary structure for obtaining a corresponding character string from the input of numeric matching numbers. In other words, in order to input "come early", the number key "68221" should be originally operated, but by operating the number key "888951", "come early" or "quick come"
It is configured so that the character string can be obtained.

The practical configuration of the dictionary device 310D is shown in FIGS. 29 and 30. That is, the number string dictionary is composed of blocks divided by the number of characters. As shown in FIG. 29, the block corresponding to each number of characters is composed of a plurality of branches corresponding to the numeral string of the number of characters. Here, there are a plurality of branches corresponding to a numeric string of 5 characters in a block having a number of characters of 5, and the branch corresponding to the numeric string “888951” among them is explicitly shown. Further, FIG. 30 shows the inside of the branch corresponding to the number string “888951”. In the branch, a table corresponding to the subsequent digits (0) to (9) when present (thus, two tables when the subsequent digits are only (1) and (8)), and the subsequent digits And the table corresponding to the code SOS (00) indicating the beginning of the candidate corresponding to the number string in the case where there is no. In the table corresponding to the subsequent numbers (0) to (9), the corresponding subsequent numbers,
The pointer NTP of the next table and the pointer NBP of the next branch are set. On the other hand, the code SOS (0
In the table corresponding to (0), there is no subsequent number (that is, corresponding to the number string “888951”), the code SOS (00) indicating the beginning of the candidate, the code of the character string corresponding to the punctuation number string, and the candidate A code EOS (FF) indicating the end of the character or candidate character string code and a code EOB (FF) indicating the end of the branch are set.

In FIG. 31, in the case where the dictionary structure of FIGS. 29 and 30 is adopted, the number of characters of 3 which is performed when the word matching number string “888951” corresponding to “early come” is input. Search processing from a block is shown. Incidentally, the dictionary device 310 according to the fourth embodiment.
Also in the text input device provided with D, the dictionary is searched by the program corresponding to the flowchart shown in FIG. Therefore, in accordance with the number string “889” having three characters in the number string “888951”, the table of the address “****” of the block having three characters is reached as shown in FIG. The subsequent number in this table is “1” and the number string “88895” stored in the character input buffer 41.
Since it is different from the fourth number “5” of No. 1, the next table is searched based on NTP. Here, the number string “88
Since the table whose subsequent number is "5" exists after the table whose number following "9" is "1", the table whose subsequent number is "5" can be searched.

If the subsequent numbers match, the N in this table
Based on the BP, the table of the address "####" of the branch "8895" having the number of characters 4 is reached. In this table, the subsequent number is “1”, which matches the fifth number “1” of the number string “888951” stored in the character input buffer 41. If the subsequent numbers match, the branch "888951" with the number of characters of 5 is based on the NBP of this table.
To the table at the address "$$$$". Here, originally, since there is no subsequent numeral stored in the character input buffer 41, a table having "00" set in the area of the subsequent numeral is searched. In the example of FIG. 31, it is premised that there is no table having numbers following the number string “888951” in the number string dictionary, and the branch “88” is used.
Immediately from the table of "951", the table in which the area of the subsequent numeral is set to "00" is reached. In this example, a code of "Hayakoi", which is a character string corresponding to the word combination number "888951", is set in the table in which "00" is set in the area, and corresponds to the output value of the code pointer 42. Then, the code is read. The subsequent processes are the same as those in the first embodiment.

In the above embodiment, the number string "888951" is input and the candidate corresponding to the word combination number string is searched first. However, the search is actually performed according to the rank of the candidate. That is, the input numeral string "88895"
When there is another candidate character string corresponding to, "Hayakukoi", "early come", etc. are stored together with the other candidate character strings. Of course, the order of the candidate character strings is changed appropriately. Further, it goes without saying that it is possible to register only the candidates corresponding to the vocabulary matching numeral string in the dictionary device.

FIG. 32 is a block diagram of a text input device according to another embodiment of the present invention. In this example,
The attribute table 18 and the fixed phrase table 1 in the central control unit 13
9 and 9 are connected, and a fixed phrase can be input. The attribute table 18 constitutes an attribute information storage means 340 in which characters or character strings corresponding to the attribute information are stored, and the fixed text table 19 has attribute information of characters or character strings to be inserted set at predetermined locations. The fixed phrase storage unit 350 in which the fixed phrase configured as described above is stored is configured.

FIG. 33 shows the contents of the attribute table 18 described above. That is, the respective words are stored in correspondence with the attribute information such as “message”, “time”, “place”, ... Further, FIG. 34 shows the contents of the fixed phrase table 19 described above. The fixed phrase table 19 stores fixed phrases in which the attribute information shown in the brackets [] is set.

The text input device of the present embodiment has a fixed text input mode, for example, a special number (a key input that is not normally used, for example, "## *? (Number)? (Number)".
Etc.) to shift to the above mode. At this time,
The central control unit 13 and the dictionary search unit 15 are shown in FIGS.
Operated by the program corresponding to the flowchart in
Since it functions as an editing means for editing a fixed phrase, the editing operation will be described below according to the above-mentioned flowchart.

First, by entering a special number or the like, a fixed sentence input mode is set, and as shown in FIG. 35, the process proceeds to the sentence pattern selection routine SB10. In the sentence pattern selection routine SB10,
The operation is performed as shown in FIG. That is, the central control unit 13 reads a fixed number of fixed phrases from the fixed phrase table 19 and gives them to the display control unit 17 to display them (S).
41). At this time, on the screen of the display device 16, FIG.
As is clear in S41, the selection number is additionally displayed for each fixed phrase. Therefore, the central control unit 13 waits for the sentence pattern number by the key operation sent from the input control unit 12 and takes it in (S42). Of course, if the required sentence pattern is not obtained by the first display, the key for seeking the next candidate, such as the next candidate key, is operated, and accordingly, the central control unit 13 selects the next fixed phrase from the fixed phrase table 19 according to this. Read a certain number of sentences,
It is given to the display control unit 17 to display it (S41). By such a process, when the desired fixed phrase is displayed, the selection is made, and the central processing unit 13 is selected in response to the selection.
For example, one fixed phrase is displayed in the editing area H of the display device 16 as shown in FIG. 38A, and the first frame of the selected sentence pattern is set as the input mode (S51).

Next, the central control unit 13 searches the attribute table 18 based on the attribute information in the first frame, retrieves the first candidate word corresponding to the attribute information, and the display control unit 1
38 to display in the corresponding area of the frame as shown in FIG. 38 (a) (S52), and shifts to the input waiting state of the selectable / non-selectable key (S53, S54). In this embodiment, the confirmation key is assigned to the “select” key and the conversion / next candidate key is assigned to the “next candidate” selection key. For this reason, when the key operation is detected, the central control unit 13 detects whether the key is the enter key or the conversion / next candidate key (S55). Here, when the next candidate key is operated, the next candidate word is selected from the attribute table 18 and displayed (S60), and it is detected whether this is the last candidate (S6).
1). As a result, if there is a next candidate, step S53.
Then, the processing is continued by returning to, and when it is the last candidate, the processing proceeds to the search routine SB20.

On the other hand, when it is detected in step S55 that the selection (confirmation) key has been operated, an instruction to put the selected candidate in the frame and display it is sent to the display control section 17 (S56), and Dictionary code for word code 1
No. 5 is set in the retrieval result character output buffer 43. As a result, the display control unit 17 causes the display device 16 to have the finalized area K.
As shown in FIG. 38B, the confirmation area K of the display device 16 is displayed up to the confirmation portion. The central controller 13 detects whether the search result character output buffer 43 has been set up to the end of the fixed phrase (S58), and if there is other undefined attribute information in the frame, sets the next frame to the input mode. (S59), the process returns to step 52 to continue the process.

In the above process, when the process proceeds from step S61 to the search routine SB20, the process shown in FIG. 37 is performed. That is, as described in the first embodiment, the word dictionary 14 is operated by operating the ten keys 103.
To obtain a candidate character or a candidate character string. The difference of the processing of this embodiment from the processing of FIG. 14 is step S3.
In No. 1, the processing from step S33 to step S35 is performed by operating the enter key.

That is, it is determined whether or not the confirmed candidate character is stored in the attribute table 18 corresponding to the attribute information (S33, S34), and when it is not registered, this candidate character or The candidate character string is registered in the attribute table 18 corresponding to the attribute information (S3).
5). That is, a means for updating the attribute table 18 is provided.

As described above, according to this embodiment, it is possible to input a fixed phrase more easily than usual, and when a part of the fixed phrase cannot be obtained from the attribute table 18, the dictionary by key input is used. Get the right candidates by searching,
You can enter sentences that are not registered as standard phrases. In addition, by updating the attribute table 18, words of attribute information that are frequently used are registered, which improves usability. In this embodiment, the read fixed phrase and the candidate are displayed in the editing area H, and the fixed portion is displayed in the fixed area K. However, in other embodiments, the fixed phrase is read within the frame of the read fixed sentence. The candidate is displayed, and the frame is deleted by confirmation. Codes such as these characters are sent to the display control unit 17 so that the central processing unit 13 can read them, and the image memory 33 of FIG.
It is stored in the character position memory 34. This has the effect of reducing the display area of the display device 16.

In each of the embodiments, by inputting the next character from the ten-key pad 103 even if the enter key is not operated, the conversion key is operated once,
There is also an embodiment in which a candidate character or a candidate character string obtained as a result of the search of the word dictionary 14 is confirmed. This is convenient because the enter key is not required to be operated when the desired candidate is displayed. It should be noted that the dictionary device of each embodiment may be provided with a learning function so that the candidate structure of the dictionary is adapted to the user of the device based on the frequency of use or by increasing the rank of the candidate of the latest use. good. As a result, frequently used candidates can be searched quickly, and improvement in operability can be expected. Further, each embodiment of the present invention can be mounted on the same device. In such an apparatus, which input method is to be adopted is configured to be switched by a special number input or a switch. With such a device, a desired input method can be selectively switched when necessary or according to the operator, which is extremely convenient.
