Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device for converting kana-kanji in an electronic device having a pen input mechanism.

[0002]

2. Description of the Related Art Recently, an electronic notebook having a pen input mechanism,
Electronic devices such as a computer system, a word processor dedicated machine (word processor), and a PDA (personal digital assistants) are used. The pen input mechanism basically inputs absolute coordinates on the display screen with a pen with respect to a device in which a display and a position detecting tablet are superposed and integrated.

Generally, the display is LC
A D (liquid crystal display) is used, and as a pen input detection method in the position detection tablet, a resistance film method, an electromagnetic induction method, a pressure sensitive method, an electrostatic coupling method, or the like is used.

The above-mentioned pen input mechanism is a coordinate position input device similar to a mouse or digitizer, and when the pen is used to indicate an absolute position on the screen or a pen is used to draw a figure on the screen, the screen is actually displayed. When you draw a figure on the screen as if you were drawing a figure with a real pen on the screen, input the drawn figure as image data, or write characters or symbols on the screen with the pen, the above-mentioned figure In addition to displaying on the screen as in the above case, it has a function of recognizing the handwritten characters and symbols and inputting them as character data.

Further, in an electronic device having a pen input mechanism, by touching a key corresponding to each character or symbol displayed on the screen or a button corresponding to each command with a pen, the character, symbol or command is touched. You can enter.

When inputting character data of Chinese characters by pen input, a method of inputting Chinese characters by handwriting with a pen and recognizing and inputting the handwritten Chinese characters, and inputting kana to be read by the pen. After that, there is a method of converting kana into kanji by kana-kanji conversion and inputting.

The kana-kanji conversion method for pen input is basically the same as the general kana-kanji conversion method used in computer systems and word processors except that kana is input by handwriting.

That is, also in the kana-kanji conversion for pen input, when a kana character string consisting of a plurality of phrases is input, the input character string is analyzed and the beginning of the character string is divided into phrases. The kana character string is converted into a kana-kanji mixed character string for each phrase.

Further, in the above-mentioned electronic device having a pen input mechanism, for example, in order to improve operability in pen input when editing a sentence, deletion,
It has a gesture function to input editing commands such as move, copy, insert, and kana-kanji conversion by the movement of the pen on the tablet.

The gesture function is, for example, such that when a cross is written with the pen on a part of the text displayed on the display screen, the part is deleted.

When the above-described operation is performed without using the gesture function, for example, after the area on the display screen where the sentence is displayed is designated by the pen, the deletion command displayed on the screen is changed. Since the button is touched with the pen, the operation becomes easier by using the above-mentioned gesture function, and a natural operation feeling close to that of an actual text editing operation on paper can be obtained.

[0012]

By the way, there are many homophones and there are a plurality of bunsetsu delimiter positions even in the same character string, and there is a possibility that the same character string has different meanings depending on the bunsetsu delimiter position. It is difficult to input a kana-kanji character string consisting of multiple clauses into a desired kana-kanji mixed sentence by one kana-kanji conversion operation in inputting Japanese.

Therefore, in the electronic device having the pen input mechanism as described above, when a kana-kanji conversion is performed by inputting a kana-character string consisting of a plurality of clauses, the part converted into an undesired kanji is displayed. It is necessary to specify the target phrase to have and select the target Kanji from the homonyms registered in the dictionary installed in the electronic device, or to change the phrase segmentation position and then perform the conversion again. Come out.

In this case, in the pen input mechanism, the position of the target phrase is designated by the pen, the new segment position of the phrase is designated, and the same button sound and the gesture function are used. There is a problem that the operation becomes complicated because it is necessary to input a command such as a word change, a phrase position change, and a reconversion.

Although it is possible to input a command and specify a region at the same time by using the gesture function, many operators are required to input various commands by using the gesture function. There is a problem that the pen operation for each command, that is, many gestures need to be memorized, and the operability cannot always be improved, and in particular, it is difficult for a beginner to handle.

An object of the present invention is to perform a kana-kanji conversion process of an electronic device having a pen input mechanism, by which an extremely easy and natural pen operation is performed during the kana-kanji conversion process to instruct the target phrase and change the phrase length of the target phrase. To do it.

[0017]

A kana-kanji conversion device according to claim 1 of the present invention comprises a conversion means for dividing an input character string into each phrase and converting kana-kanji for each phrase, and a display screen. The coordinates of the arbitrary position are displayed by bringing the display means for displaying the input or kana-kanji converted character string on the display screen and the indicator for indicating the coordinate position close to or in contact with the arbitrary position on the display screen. When the display coordinate position input means capable of inputting a position and the coordinate position in the area of an arbitrary phrase of the character string displayed on the display screen are input by the display coordinate position input means, the arbitrary phrase The phrase length of the attention phrase is extended when the attention phrase determination means having the attention phrase as the attention phrase and the coordinate position input from the display coordinate position input means with respect to an arbitrary part of the attention phrase are continuously distant, or A bunsetsu length changing means for shortening the bunsetsu length of the bunsetsu of interest when the coordinate position input from the coordinate position input means successively approaches an arbitrary part of the bunsetsu of interest. To do.

Further, in the kana-kanji conversion device according to the second aspect of the present invention, when the coordinate position in the region of the noticed phrase is input, the character strings after the noticed phrase of the converted character string are converted before kana-kanji conversion. The phrase length changing unit changes the phrase length of the target phrase in the character string inversely converted by the inverse conversion unit.

[0019]

According to the configuration of the first aspect, it is possible to make an arbitrary phrase of the character string displayed on the screen a target phrase by touching and pointing with an indicator, for example, a pen, and , It is possible to extend the bunsetsu length by tracing the display screen with a pen so as to move away from any part of the bunsetsu bunsetsu, for example, the beginning character of the bunsetsu bunsetsu. The phrase length can be shortened by tracing the display screen with a pen.

That is, it is possible to specify the target phrase, shorten the target phrase, and extend the target phrase by extremely simple and intuitive pen operation, so that the operability of pen input can be significantly improved. it can.

In the operation of the pen, when the pen is moved away from an arbitrary part of the phrase, the phrase is extended and the end (or head) of the phrase from the arbitrary part of the phrase.
When the pen is moved closer to an arbitrary part of the phrase, the phrase is shortened and the end (or beginning) of the phrase approaches the arbitrary part of the phrase. The end (or beginning) movement of the phrase will match, and you can change the bunsetsu length with an extremely intuitive operation as described above. Even if you do not have a hard time remembering how to change the bunsetsu length, If you try it, it will be remembered, so
A person operating the Kana-Kanji conversion device of the present invention for the first time can easily change the phrase length.

According to the above-mentioned structure of claim 2,
After the target phrase is specified as described above, the character string after the target phrase can be returned to the state before the kana-kanji conversion by a simple operation of touching the target phrase again with the pen.

Then, in the character string returned to the state before the Kana-Kanji conversion, the phrase length can be accurately adjusted in units of one kana to be read by operating the pen.

[0024]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A kana-kanji conversion device according to an embodiment of the present invention will be described below with reference to the drawings. The kana-kanji conversion device of this embodiment is installed in an electronic notebook, computer system, word processor, PDA, or other electronic device having the above-described pen input mechanism, and is not necessarily used alone.

FIG. 1 shows a basic configuration of a kana-kanji conversion device (electronic device equipped with the kana-kanji conversion device) of the present invention. As shown in FIG. 1, the kana-kanji conversion device of the present invention uses kana-kanji conversion, determination of a target phrase, change of phrase length, re-conversion, etc., based on operation of a pen (illustrated in FIG. 6, etc.) p as described later. And a CPU (central processing unit) that realizes the functions of the electronic device as described above.
nit) 1, a ROM (read only memory) 2 in which data necessary for the arithmetic processing of the CPU 1 is stored, and the CP described above.
R to temporarily store the data output from U1
Work memory 3 composed of AM (random access memory) and SRAM for storing input documents
A document memory 4 including (staticRAM) or flash memory, a liquid crystal display unit 5 for displaying data output from the CPU 1, and a liquid crystal display unit 5 output from the CPU 1 and displayed on the liquid crystal display unit 5. VRAM (video RAM) 6 for storing the display data of No. 1 corresponding to the coordinate position on the screen of the liquid crystal display unit 5 and a video signal for inputting the display data stored in the VRAM 6 to the liquid crystal display unit 5. A display control unit 7 for conversion and a transparent touch panel (coordinate position detection device) 8 arranged on the liquid crystal display unit 5 in an overlapping manner and outputting the coordinate position of the pen p operated on the screen as an electric signal. And a coordinate detection unit 9 for converting an electric signal output from the touch panel 8 into a digital signal indicating a coordinate position.

Further, in the work memory 3, as shown in FIG. 1, an area of the input buffer 3a in which a character string before kana-kanji conversion which is input by handwriting or by a key displayed on the liquid crystal display unit 5 is stored. When an input character string is subjected to kana-kanji conversion processing, a conversion candidate buffer 3b in which characters such as kanji characters retrieved from a dictionary registered in the ROM 2 corresponding to each clause of the character string are stored for each clause. The phrase information buffer that stores the number of characters and the phrase length (number of bytes) of each phrase in order from the beginning of the character string when Kana-Kanji conversion processing is performed on the area and the input character string and divided into each phrase. An area 3c and a target clause number register 3d that stores a target clause number indicating an order on a character string divided into each clause of a target clause t (illustrated in FIG. 5) designated by the pen as described later. of A band, a region rephrasing fix flag 3e is stored indicating whether the mode or not to change the once determined phrase length is ensured.

The character string input to the input buffer 3a is processed by kana-kanji conversion or the like, the character string is determined and stored in the document memory 4, and then the next character string is input. It is designed to be updated to a character string. Therefore, in the stage before the character string is fixed, it is possible to call the input character string, and after the input character string is converted to Kana-Kanji, it is also converted back to the original input character string. can do.

The conversion candidate buffer 3b is adapted to store a plurality of homonyms for each phrase when a plurality of homonyms are retrieved from the dictionary for each phrase. . The document memory 4 stores the character string input and confirmed as described above.

The touch panel 8 is referred to as a touch when the pen p comes into contact with it (or when it comes close to it).
To output an electric signal indicating the coordinate position on the touch panel 8 corresponding to the contact position, such as the resistance film method, the electromagnetic induction method, the pressure sensitive method, and the electrostatic coupling method shown in the conventional example. The coordinate position detecting device can be used as the touch panel 8.

The coordinate position of the display data displayed on the liquid crystal display unit 5 and the coordinate position on the touch panel 8 are made to correspond by a predetermined coordinate conversion. When the position of the display data displayed on the overlapping liquid crystal display unit 5 is touched with the pen p, the coordinate position output from the touch panel 8 is converted into the coordinate of the position of the display data on the screen of the liquid crystal display unit 5. The CPU 1 can recognize that the position indicated by the pen p is the position of the display data.

The kana-kanji conversion device having the above-described structure has the same well-known functions as the electronic device having the pen input mechanism shown in the conventional example. Further, the kana-kanji conversion device collectively collects a kana character string (including symbols, alphabets, numbers, etc.) input by handwriting or by a key displayed on the liquid crystal display unit 5 based on the arithmetic processing of the CPU 1. The following processing is performed by operating the pen p corresponding to the touch panel 8 from the stage of conversion into a kana-kanji mixed sentence to the stage before the converted kana-kanji mixed sentence is completely determined and stored in the document memory 4. Has the function of performing.

First, in a state in which a character string that has been converted into Kana-Kanji characters before confirmation is displayed on the liquid crystal display unit 5, that is, in a Kana-Kanji conversion mode, a pen p is placed on the screen of the liquid crystal display unit 5 overlaid on the touch panel 8. If you touch,
That is, when the touch panel 8 senses the pen p and the coordinate position pointed to by the pen p corresponds to one phrase in the character string before being determined, the phrase has the function of setting the focused phrase t.

Further, the position of the target phrase t on the screen is set with the pen p
When is touched with, it has a function of returning the character string after the target phrase t to the state in which it was input with the kana before conversion. In addition, when the character string after the target phrase t is returned to the state of the kana before conversion, it has a function of setting the first one character of the target phrase t returned to the kana as a new target phrase t.

Then, when the pen p is moved to the right while the touch panel 8 is being touched on the right side of the leading character of the focused phrase t returned to the state before conversion as described above, the focused phrase is touched. By extending t to the right, a new noticeable phrase t is obtained from the first character of the noticeable phrase t to the character closest to the point where the movement of the pen p is stopped (or the point where the pen p is separated from the touch panel 8). Has the function of

Further, when the pen p is moved to the left while the pen p is in contact with the touch panel 8 on the right side of the leading character of the target phrase t returned to the state before conversion as described above, The phrase t is compressed toward the left, and the characters from the leading character of the noticed phrase t to the character closest to the point where the movement of the pen p is stopped (or the point where the pen p is separated from the touch panel 8) are newly noticed phrases. It has the function of being t.

Next, a method of changing the phrase length in the kana-kanji conversion processing by the kana-kanji conversion device having the above configuration will be described. 2 is a flowchart showing a method of changing a phrase length, FIG. 3 is a flowchart showing a re-conversion method after changing a phrase length, and FIGS. 4 to 10 are liquid crystal in a kana-kanji conversion process including a conversion process of a phrase length. Display unit 5
It shows the display of the character string. Further, FIGS. 5 to 10 also show the information of the phrase information buffer 3c and the noticed phrase number register 3d.

First, in the kana-kanji conversion device, a character string to be subjected to kana-kanji conversion is input by the pen P as described above. It is also possible to connect a keyboard to the kana-kanji conversion device and input a character string to be used for kana-kanji conversion from the keyboard.

Then, the input character string is sequentially stored in the input buffer 3a of the work memory 3. In addition to the input of the character string, the font data is read from the ROM 2, for example, by the CPU 1, is output to the VRAM 6, and is displayed on the liquid crystal display unit 5 via the display control unit 7 as shown in FIG.

4 to 10, the inside of a rectangular frame shows a character string displayed on a part of the screen of the liquid crystal display unit 5. In addition, here, it is assumed that "Kyowa is a good tenki" is entered as the character string, and FIGS. 4 to 10 show an example in which the above character string is entered.

Next, for example, a conversion key (not shown) displayed on the screen is touched with the pen p, or a conversion command is input by the gesture function. Then, kana-kanji conversion is performed by a known method. That is, the dictionary is searched based on the input character string, the character string is analyzed, and the character string is divided into clauses sequentially from the beginning, and candidate character strings that are candidates from the dictionary (kana-kanji mixed Character strings) and assign candidate character strings to each clause.

At this time, the candidate character string of each phrase is stored in the conversion candidate buffer 3b of the work memory 3 for each phrase. In addition, at this time, when a plurality of candidate character strings (synonyms) are searched for one bunsetsu when searching the dictionary for each bunsetsu, these plural candidate character strings are converted to conversion candidates. Store in buffer 3b.

Further, the homonyms are selected based on the analysis result of the part of speech and the context when the character string is analyzed, and if a plurality of candidate character strings still remain after the selection, they remain. From the plurality of candidate character strings, one candidate character string is set as the highest priority candidate based on a predetermined priority order, a character string composed of the highest priority candidate for each clause is created, and the character strings forming the character string are The font is output to the VRAM 6, and the character string converted as a kana-kanji converted character string is displayed on the liquid crystal display 5 as shown in FIG.

Here, "Today is a good weather." Is the first conversion. "Today is a good weather."
It has been converted to. When the conversion process is performed, the character string is divided into each clause as described above. At this time, the number of characters and the clause length (the number of bytes) of each clause are shown in FIG. Thus, it is stored in the clause information buffer 3c of the work memory 3.

The above string "Today is good weather."
In this case, the character string is divided into five bunsetsu underlined as shown in FIG. 5, and the number of characters and bunsetsu length of each bunsetsu are stored in the bunsetsu information buffer 3c. In addition, after the kana-kanji conversion of the character string, the first phrase of the character string is set as the target phrase t, and the target phrase t is highlighted so that the target phrase t can be seen on the screen.

In FIGS. 5 to 10, the portion which is actually displayed in reverse is surrounded by a rectangular frame. Further, the noticeable phrase number register 3d stores the noticeable phrase number (here, 1) indicating the order of the noticeable phrase t from the beginning of the character string.

Next, a method of changing the phrase length shown in FIG. 2 will be described. Here, it is assumed that the character string input as described above has been converted by the kana-kanji conversion processing and has not been finalized. In this state, the CPU 1
It is in a state of waiting for the coordinate position input from the touch panel 8.

That is, the pen p is touched on the touch panel 8, an electric signal indicating the coordinate position is output from the touch panel 8, and a digital signal indicating the coordinate position is input to the CPU 1 via the coordinate detection unit 9, that is, the pen. When p is touching the touch panel 8 (pen down or pen run) or not (pen up), it is detected, and when the pen p touches the touch panel 8, the touch panel 8 outputs it as an electric signal. Then, the coordinate detection unit 9 is in a state of performing an input coordinate acquisition process of acquiring the coordinate position on the liquid crystal display unit 9 from the coordinate position on the touch panel 8 which is converted into a digital signal and input to the CPU 1 (step S1). ).

Next, in the input coordinate acquisition process, it is determined whether or not the pen is in a pen-up state (step S2). Then, in the case of the pen-up state, when the electric signal indicating the coordinate position is output from the touch panel 8, the process returns to step S1 to acquire the coordinate position.

If it is not pen-up, that is, if the coordinate position on the liquid crystal display unit can be acquired from the coordinate position on the touch panel 8 of the pen tip in step S1, then the coordinate position is changed. It is detected whether the state is a pen run (pen run) or the state is not fluctuating (pen down) (step S3). And in the case of pen down,
It is determined whether the position of the pen p is within the region of the target phrase t of the converted character string on the liquid crystal display unit 5 (step S).
4).

In the character string displayed as shown in FIG. 5, each character basically has a rectangular display area, and the combination of the display areas of the respective characters of the target phrase is the target phrase. Is the display area of the character string, and the display area of all the characters in the character string is the display area of the character string.

Although omitted here, in the actual process, the coordinate position on the liquid crystal display unit 5 touched by the pen p at the stage before step S4 or step S3 is the display area of the character string. The display area of the command key (not shown) displayed on the liquid crystal display unit such as above, deletion, and confirmation, or the display area of other buttons and keys displayed on the liquid crystal display unit 5 It is determined whether the part does not belong to the area.

If the position of the pen p is in the display area on the character string, the process proceeds to step S3 or step S4. If it is in the display area of the command key or other keys or buttons, the respective keys or buttons are displayed. Based on the above, the process is terminated, or the process returns to step S1 and the pen p
When the position of is a part that does not belong to these display areas,
It returns to step S1.

Next, in step S4, the target phrase t
When a coordinate position in the display area of another phrase other than is input, the phrase in the display area including the input coordinate position is set as the target phrase t, and the target phrase number register 3d of the work memory 3 stores the target phrase t. The target clause number of is stored and the process returns to step S1 (step S5).

That is, in FIG. 5, the first phrase "today" is the target phrase t, whereas the display area of "good" in the third phrase is displayed with the pen p as shown in FIG. When touched, this third phrase is set as the target phrase t, and 3 is stored as the target phrase number in the target phrase number register 3d. At this stage, since the clause length of each clause has not been changed, the clause information buffer 3c remains as it is as shown in FIG.

In step S4, when the coordinate position in the display area of the target phrase t is input by the pen p, each phrase after the target phrase t is stored in the input buffer 3a before the Kana-Kanji conversion. To the character string (step S6). For example, as shown in FIG.
When the "good" area is touched again with the pen p after "good" is set as the attention phrase t, as shown in FIG.
The string "Good weather." After the 3rd sentence is returned to "Good weather." Before Kana-Kanji conversion.

Next, in the portion after the target phrase t that has been returned to the character string before the kana-kanji conversion, that is, the part where the phrase is changed (recut), the first character is set as the target phrase t (step S7). . For example, as shown in FIG. 7, "yo" of "Yotenki." Is the target phrase t.

At this time, since there is no change in the clauses before the noticed clause t, the value of the noticed clause number register 3d remains 3, but in the document information buffer 3c,
Since the third bunsetsu of the target bunsetsu t is one character, the number of characters is set to 1 (2 bytes), and the part after the third bunsetsu is returned to the state before kana-kanji conversion, that is, before the bunsetsu division, One fourth clause, and the number of characters becomes the number of characters in the remaining character string, 7 (14 bytes).

Next, the phrase recut flag 3e of the work memory 3 is turned on (step S8). On the other hand, if it is determined in step S3 that it is a pen run, it is determined whether or not the phrase recut flag 3e is turned on (step S9).

That is, as described above, the target clause t has already been set.
It is determined whether or not the subsequent state has been converted to the character string before the kana-kanji conversion. If the phrase recut flag 3e is not turned on, the process returns to step S1 and the pen p
It becomes the state of waiting for the input of the coordinate position by.

If the phrase recut flag 3e is turned on, it is next determined whether or not the pen run is performed at the coordinate position on the right side (including the target phrase t) of the target phrase t (including the target phrase t). Step S10). When the pen run is performed on the left side of the target phrase t, the process returns to step S1 and waits for the input of the coordinate position by the pen p.

When the pen run is performed on the right side of the target phrase t, it is determined whether the pen run is performed toward the right side (step S11). That is, when the direction along the direction of the character string (left-right direction) of the liquid crystal display unit 5 is the X-axis direction and the X coordinate of the left end of the liquid crystal display unit 5 is 0, the X coordinate is increased. It is determined whether the coordinate position fluctuates and the coordinate position is input to the CPU 1 from the touch panel 8 via the coordinate detection unit 9.

When the pen-run is performed toward the right side, from the head of the current target phrase t to the character displayed in the display area including the x-coordinate at which the pen-run to the right side ends, one character is noted. The clause t is set (step S12).
That is, the process of expanding the target phrase t is performed.

For example, as shown in FIG. 7, after the noticeable phrase t is returned to "Yoi Tenki." Which is the state before the kana-kanji conversion, and the leading "yo" is the noticeable phrase t, By performing a pen run as shown in FIG. 8, "yoten" is set as the target phrase t.

At this time, in the phrase information buffer 3c, as shown in FIG. 7, the number of characters of the third phrase is increased from 1 (2 bytes) to 4 (8 bytes), and only the third phrase is increased. The number of characters in the 4th clause is from 7 (14 bytes) to 4 (8
Bytes). When the pen run is performed up to the rightmost character in the character string, all the parts on the right side of the target phrase t in the character string are regarded as one target phrase.

When the process of expanding the target phrase t is completed, the process returns to step S1 to wait for the processes such as re-modification, re-conversion, and confirmation of the target phrase t.
Further, when the pen run is performed toward the left side, from the head of the current target phrase t to the character displayed in the display area including the x coordinate where the pen run to the left side is completed is one target phrase t. Yes (step S13). That is, the target phrase is compressed.

When the pen run is performed before the first character of the target phrase t, the target phrase t is compressed to only the first character of the target phrase t. In addition, as shown in FIG. 7, after the focused phrase t, it is returned to "Good Tenki.", Which is the state before kana-kanji conversion, and at the beginning, "yo".
In the state in which is the target phrase, the target phrase t is in the shortest state, so there is no point in performing compression processing.

Therefore, this compression processing is performed in the above step S.
This is used when the length of the target phrase t is changed again after the target phrase t is expanded in 12. For example, as shown in FIG. 8, after "yoten" is set as the attention phrase t by the expansion processing of the above-mentioned attention phrase t, as shown in FIG. By performing a pen run to the left side up to the display area, the target phrase t can be compressed to "good".

At this time, in the phrase information buffer 3c, as shown in FIG. 9, the number of characters in the third phrase is reduced from 4 (8 bytes) to 2 (4 bytes), and only the amount of decrease in the third phrase is generated. The number of characters in the fourth clause increases from 4 (bytes) to 6 (12 bytes). Then, when the process of compressing the target phrase t is completed, the process returns to step S1 and waits for the processes such as re-modification, re-conversion, and confirmation of the target phrase t.

The process of the flowchart shown in FIG. 2 is actually ended when a command such as confirmation or conversion is selected and the process is executed as described above. The phrase re-cut flag 3e is turned off.

By the phrase length changing process as described above, by touching with the pen p an arbitrary phrase region of the character string that has been converted into kana-kanji characters on the liquid crystal display unit 5 overlaid on the touch panel 8, The attention clause t can be designated. In addition, by touching the phrase region that is the target phrase t with the pen p again, the region after the target phrase t is set to the state before kana-kanji conversion, and the length of the target phrase t can be designated by the pen p character by character in the kana state. It can be in a state.

Further, in the above-mentioned state, by moving the pen p on the liquid crystal display portion 5 overlapped with the touch panel 8 to the right while touching the pen p, the target phrase t can be extended. Further, by moving the pen p on the liquid crystal display unit 5 overlaid on the touch panel 8 while the pen p is touched, the target phrase t can be compressed.

That is, by specifying the position of one point with the pen p, or by moving the pen p left and right to specify the position, the target phrase t is changed, and the reverse conversion to the state before the conversion after the target phrase t is performed. You can instruct to expand the phrase length, compress the phrase length, and to change the phrase length, you do not need to input commands with specifying the position, and you do not need to remember many pen movements as gestures. Since the above process can be performed by a very simple operation that makes the process of decompressing and compressing the phrase length intuitive, the operability of the pen p during the process of changing the phrase length in kana-kanji conversion is significantly improved. Can be improved.

Next, after the phrase length is changed as described above, re-conversion is performed by touch input of the conversion key. In this case, the re-conversion is performed as shown in the flowchart of FIG. 3, but this re-conversion is an example, and the re-conversion is basically performed by the well-known kana-kanji conversion process.

First, the CPU 1 acquires a character string to be read before the kana-kanji conversion of the target phrase t (step A1).
Next, the dictionary is searched based on the character string (step A2). Then, a candidate character string such as a kana-kanji mixed character string that is a candidate is acquired from the dictionary (step A3).

In this case, when there are a plurality of candidate character strings as described above, a plurality of candidate character strings are acquired and the highest priority candidate is determined. Next, it is determined whether or not there is a next phrase (remaining character string) after the phrase for which the dictionary search processing is performed as described above (step A4). Then, if there is the next phrase, the phrase length of the next phrase is obtained by analyzing the character string, the character string before the Kana-Kanji conversion of the phrase having the above phrase length is acquired (step A5), and the process returns to step A2. ,
The processing up to step A4 is performed.

In step A4, while it is determined that there is a next phrase, that is, until there is no next phrase, the above steps A5 and A2 to A4.
Repeat the process up to. If it is determined in step A4 that there is no next phrase, the phrase information buffer 3c is updated (step A6), and
The font of the character string after kana-kanji conversion consisting of the character string of the highest priority candidate of each phrase is output to the VRAM 6, and the display control unit 7
The character string after kana-kanji conversion is displayed on the liquid crystal display unit 5 via (step A7).

For example, as shown in FIG. 10, the reconverted character string is displayed on the liquid crystal display unit 5. In this case, the character string after the focused phrase t whose phrase length has been changed as described above is re-converted, and the phrase length of the focused phrase t is the length determined by the above operation. After the re-conversion, the length of each phrase is determined by analyzing the character string after the focused phrase t, and the length of each phrase is stored in the phrase information buffer 3c.

In the above-mentioned change of the phrase length shown in FIG. 5 to FIG. 9, the length of the target phrase t is finally restored, so that the target phrase t is "good" at the time of reconversion. The candidate character string "I like" that is secondly prioritized is selected and displayed from the candidate character strings that read "." Then, when the confirmation command is input by the pen p, the above-mentioned kana-kanji converted character string is stored in the document memory 4.

The conversion process is for re-conversion when the phrase length of the target phrase t is changed. If the conversion command is input without changing the phrase length,
Since the target character string is a character string that is not the highest priority candidate character string at the time of the first conversion, the candidate character string with the second highest priority is selected from the multiple candidate character strings acquired first. Alternatively, all the candidate character strings are sequentially displayed on the liquid crystal display unit 5 according to the operator's instruction, and the operator is allowed to select the desired candidate character string.

As described above, according to the kana-kanji conversion device of this embodiment, in the process from kana-kanji conversion to confirmation, the target phrase t can be changed and the target phrase can be changed by the extremely simple and intuitive operation with the pen p as described above. It is possible to invert the character string after t to the state before the Kana-Kanji conversion and change the phrase length of the target phrase t, and the operability of the instruction with the pen p as described above can be significantly improved. .

As described above, the kana-kanji conversion device of the present invention can be used in any electronic device having a pen input mechanism, and is not limited to the configuration shown in FIG. The present invention can be applied to an electronic device having a coordinate position inputting means and a displaying means for use, and a necessary storing means. Further, when a coordinate position detecting device such as a pressure-sensitive type which does not necessarily require a dedicated pen p for input is used as the touch panel 8, a finger or other tool is used as an indicator of the present invention instead of the pen. Can be used.

According to the kana-kanji conversion device of the first aspect, the operation of the pointing body (pen) that is extremely simple and intuitive allows designation of the target phrase, shortening of the target phrase, and extension of the target phrase. Therefore, the operability of pen input can be significantly improved.

According to the kana-kanji conversion device of the second aspect, the character string after the target phrase is returned to the state before the kana-kanji conversion by a simple operation, and the character string is returned to the state before the kana-kanji conversion. On the other hand, by operating the above-mentioned pen, the phrase length can be accurately adjusted in units of one character that is readable.
