BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device, and more particularly, to a kana-kanji conversion device applied to a document information processing device such as a word processor, a personal computer, an electronic notebook, a portable information terminal, a POS terminal, a workstation and the like.

2. Description of the Related Art Conventionally, in a kana-kanji conversion device applied to a document information processing device, when converting a kana character string consisting of a single phrase or a plurality of phrases into a kanji-mixing candidate, depending on how to divide the phrase, the sentence may be divided into sentences. Since it is erroneously converted into a irrelevant candidate, there is a problem in that the user is forced to make an extra judgment and a complicated operation in order to correct this erroneous conversion into an intended candidate. Therefore, the following conventional example has been proposed as an improved technique for converting an input character string into an intended candidate for kanji mixing.

Conventional Example 1: As described in Japanese Patent Application Laid-Open No. 3-29051, a conversion key for converting kana-kanji is used for a certain period of time.
A "kana-kanji conversion device" has been proposed which is provided with a delimiter changing means for changing a delimiter of a word when a key is kept pressed, and a means for performing two functions of conversion and delimiter change with the same key. FIG. 15 is an explanatory diagram showing an example of Kana-Kanji conversion of Conventional Example 1. As shown in FIG. 15, for example, "Because of this" is input and the conversion key is pressed. → "For this" → (Continue to press the conversion key) → "This eye" → (Continue to press the conversion key) → "For this reason" If you press and hold the conversion key for a certain period of time, each character will be shortened by one character. Make a forced break change. In Conventional Example 1, that is, the reading character is shortened one by one with respect to the target conversion result, and the forced separation conversion is performed. It may be shortened one character at a time from the front or the back of the corresponding word. This break change is generally [Shift] key +
It is commercialized under the name of phrase shortening by using the [←] key or the [Function] key + [←] key.

Conventional Example 2: As described in Japanese Patent Publication No. 6-3595, a partial change candidate character or character string is displayed corresponding to each of a plurality of partial reading input characters or character strings having different delimiter lengths. A "reading input character string conversion candidate display method and device" has been proposed.
FIG. 16 is an explanatory diagram showing a kana-kanji conversion example of the second conventional example. As shown in FIG. 16, for example, "teikankan ni ni" is input and the change key is pressed. → "For low temperature" →
(Correction operation) → "Low temperature *", "Low *" → Select →
"To inspire", "to the environment", "interval *" → select →
"Pitch *" → select → "Go", "Today", "Kyoni" When the correction operation starts, "Low temperature *" and "Low *" are displayed. The subsequent candidates are displayed so that they can be selected. In Conventional Example 2, to correspond to each partial input character or character string means to display candidates having different first delimiters before the conversion result of the consecutive clause conversion, and to associate them with the conversion candidate characters or The character string is displayed and can be selected.

Conventional Example 3: As described in Japanese Patent Application Laid-Open No. 3-226858, among the converted candidates of the other kana-kanji kanji character strings having different cutting methods, a plurality of candidates having the same cutting method are set as one candidate. A "kana-kanji conversion / correction method" has been proposed, which has means for displaying as a representative and selecting a temporary candidate from among them. FIG. 17 is an explanatory diagram showing a kana-kanji conversion example of Conventional Example 3. As shown in FIG. 17, for example, input “Hakoko kobu kobu” and press the change key. "By Car ⌒ ｜ Carry Child ⌒ ｜ Carriage" Car ⌒ ｜ Carry Box ⌒ ｜ Carry "Until Coming ⌒ ｜ Carry Child ⌒ ｜ Carry""Come between ｜ Carry Child ⌒ ｜ Carry" Converted characters Among the candidates for the character string that is cut differently from the row, a plurality of candidates with the same cutting method is displayed as one candidate, and a temporary candidate is selected from the candidates. In Conventional Example 3, candidates with different delimiter positions are displayed and can be selected, that is, the range of candidate selection is not limited even when the number of clauses in the conversion result is large, and no matter how many candidate combinations are combined. At most, those candidates are displayed and selected.

[0006]

However, in the "Kana-Kanji conversion device" described in Japanese Patent Laid-Open No. 3-29051 of prior art 1, when the conversion key having two functions of conversion and division change is pressed continuously, , It is possible to change the delimiter, but this delimitation unconditionally shortens the reading character position of the corresponding clause by one character and performs Kana-Kanji conversion again. Kana-Kanji conversion has the original conversion character string. The grammatical connections will be ignored and the correct answer may not always be reached quickly. If the number of reading characters is large,
For example, if there are 10 characters and the fifth character is the correct answer delimiter position, the correct answer will be reached at the fifth time, and the number of operations may increase. Since the delimiter position is mechanically shortened in this way and the conversion result is output,
Unnecessary candidates are output many times before reaching the candidate at the desired break position, which may impair usability.

Further, in the "Method and apparatus for displaying conversion candidates of reading input character string" disclosed in Japanese Patent Publication No. 6-3595 of Conventional Example 2, the cursor is sequentially moved from the front to the desired one in the input consecutive phrase conversion. To select candidates for
It's annoying to move the cursor.

Further, Japanese Patent Laid-Open No. 3-226858 of Conventional Example 3
In the "Kana-Kanji conversion / correction method" described in Japanese Patent Publication, when the number of clauses in the conversion result increases, the number of combinations increases, and it takes time and effort to select a desired candidate, resulting in poor usability.

Therefore, it has been desired to improve the items described in detail below. (1) It is easy to select a desired candidate by displaying where the break position is. (2) For example, a marker is moved for each delimiter position so that the delimiter position can be easily understood, and a desired delimiter position can be easily selected and converted. (3) In the first conversion, only the display of the break position and the first conversion candidate is limited to the minimum necessary display, and when the selection of the desired break position or the selection of the homophone is necessary, the position is marked by the marker. It is specified so that a desired candidate can be easily selected even if the number of candidates is large. (4) When two delimiter positions may occur on one conversion candidate (kanji), the conversion candidate is changed to reading information and the delimiter position is clarified when conversion is corrected. (5) For example, by moving the marker indicating the delimiter position automatically at a constant cycle, and pressing the key for selecting the delimiter position when the marker reaches the desired delimiter position, conversion candidates with different delimiter positions can be obtained. To be able to select. (6) For example, the marker indicating the break position is automatically moved at a constant cycle, and when the desired break position is reached, the movement of the marker is stopped by pressing the key for selecting the same sound word. To be able to. (7) For example, the moving speed of the marker indicating the break position can be set so as to match the optimum operation speed of the user. It also expands the options so that the marker can be moved automatically or only when the key is held down.

The present invention has been made in consideration of the above circumstances. By indicating a delimiter position to be converted by a marker,
It is an object of the present invention to provide a kana-kanji conversion device capable of suppressing unnecessary display of candidates and performing conversion and correction to intended candidates by a simple operation.

Is a display device including a CRT display and an LCD (liquid crystal) display.

The function of the configuration of the present invention will be further described. In FIG. 1, an input unit 101 has a function of inputting a character key for inputting a kana character string consisting of a single phrase or a plurality of phrases, a command for conversion, setting, selection, etc. It is equipped with a key. The kana-kanji conversion unit 102 refers to the dictionary unit 102a, analyzes the clauses of the input kana character string, generates all the delimiter positions to be the clauses, and outputs the kana character string corresponding to the generated delimiter clauses as a kanji-kana intermingled sentence candidate. Is to be converted to. Since the character information storage unit 103 stores the input kana character string, all generated delimiter positions and their conversion candidates, the kana-kanji conversion unit 102 does not need to repeatedly convert phrases having different delimiter positions. The key press time determination unit 104 measures and determines whether the press time of the conversion key 101a is within a predetermined time. As a result of the determination, when it is determined that the conversion key 101a has been pressed for a predetermined time or longer, the marker moving unit 105 generates a marker indicating the delimiter position of the conversion candidate and moves the marker at each delimiter position in a constant cycle. Kana-Kanji conversion unit 102
Converts the homonym candidate if the conversion key 101a is pressed for a predetermined time, and after converting the homophone, converts the candidate for the delimiter position indicated by the moved marker when the conversion key 101a is pressed and released for a predetermined time or longer. Fix it. As a result, when the first converted homophone conversion is not a desired conversion candidate, if the conversion key 101a is further pressed, the marker is moved at every delimiter position at a constant cycle, and when the marker is at the desired delimiter position. By releasing the conversion key 101a, the delimiter position can be selected and the candidate can be converted and corrected.
Therefore, one conversion key can be used to select conversion candidates having different homophones and different delimiter positions. In addition, since the first conversion is limited to displaying the delimiter position and only the first conversion candidate, it is not necessary to display unnecessary conversion next candidates. Can be easily selected.

A delimiter position discriminating unit 107 for discriminating whether or not there are two or more delimiter positions on one converted candidate when the conversion key 101a is pressed for a predetermined time or longer.
Further, if the configuration further includes a reading restoration unit 108 that restores the conversion candidate to the original reading information when there are two or more delimiter positions on one conversion candidate, the Kana-Kanji conversion unit 102 When a marker indicating the delimiter position of the reading information restored by the reading decompression unit 108 is selected by the operation of the conversion key 101a, the candidate of the delimiter position is converted and corrected, so that the delimiter position is set on one conversion candidate (kanji). When there are two or more, the conversion key 10 for selecting a homophone
By holding down 1a and moving the marker, the once-converted candidate is restored to the reading information, and the delimiter position included in the reading information can be selected to correct the candidate. Therefore, when two delimiter positions may occur on one conversion candidate (kanji), the conversion candidate can be changed to reading information and the delimiter position can be clarified when conversion is corrected.

A delimiter position discriminating unit 107 for discriminating whether or not there are two or more delimiter positions on one converted candidate when the conversion key 101a is pressed for a predetermined time or longer.

If the configuration further includes a character spacing calculation unit 110 that calculates the converted candidate character spacing, the reading restoration unit 108 enlarges the characters of the original reading information so as to fit within the candidate character spacing.・ Can be reduced.
Normally, the characters are displayed at equal intervals, so if the candidate (kanji) is restored to the original reading information, the marker will be difficult to move to the left or right, but this will cause the restored input kana character string to Since the characters are displayed with the character width changed so as to be within the candidate character interval, the delimiter position included in the restored reading information is easy to see and selection is easy.

The input unit 101 is for automatically moving a marker after conversion of a candidate at each delimiter position in a constant cycle, and a marker movement automatic setting key 101b for selecting a delimiter position and converting and correcting the delimiter position candidate. If the marker moving section 105 is further provided with a break position selection key 101c, the marker moving unit 105 moves the marker at every break position at a fixed cycle according to a movement command from the marker movement automatic setting key 101b, and at the same time, the break position selection key 101c. Since the selection is stopped at a desired delimiter position by a selection command from, the marker movement automatic setting key 101b is set in advance so that the marker automatically moves for each delimiter position at a constant cycle, and the input character string is converted by the conversion key. Then, the marker is used until the desired break position is selected by the break position selection key 101c. Dynamic and it can be converted modify the candidate corresponding to the break position at the same time delimiting position is selected.

The input unit 101 selects a marker movement automatic setting key 101b for automatically moving a marker at each delimiter position at a constant cycle after candidate conversion, and selects a delimiter position to convert a phrase at the delimiter position into a homophone. If the configuration further includes a homophone selection key 101d, the marker moving unit 105 moves the marker at each delimiter position at a fixed cycle in response to a movement command from the marker movement automatic setting key 101b, and selects a homophone. Since the selection is stopped at a desired break position by a selection command from the key 101d, the marker movement automatic setting key 101b is set in advance so that the marker is automatically moved in a predetermined cycle for each break position.
When the input character string is converted by the conversion key, the marker moves until the desired break position is selected by the homophone selection key 101d, and at the same time when the break position is selected, the phrase corresponding to the break position is changed to the homophone. Can be converted to candidates. Further, if the homophone selection key 101d or the conversion target character string is not input again within a fixed time, the marker can be restarted.

A mode setting section 111 for setting whether the marker after the candidate conversion is automatically moved by the marker movement automatic setting key 101b or a pressing operation of the conversion key is set, and marker setting information such as the speed setting of the marker. The display unit 107 further includes a stored marker information storage unit 112, and the display unit 107 has a function of displaying a setting screen for setting the speed setting of the marker and the automatic movement / manual movement of the marker. An automatic / manual mode can be set on the setting screen whether the marker is automatically moved at a fixed time interval or, for example, when the conversion key is continuously pressed. Further, the moving speed (cycle) of the marker can be set according to the optimum operation speed of the user.

FIG. 8 is an explanatory diagram showing a display example of the setting screen of the present invention. The flowchart of FIG. 3 and FIGS.
The specific Kana-Kanji conversion processing examples 1 to 5 of the present invention will be described using the display examples of. In FIG. 3, the following steps 301 to 319 operate as modules (functional units). Step 301: Conversion target determination module Step 302: Conversion, homophone selection key determination module Step 305: Key state detection processing module Step 306: Key off detection module Step 308: Marker movement mode determination module Step 309: Kana-Kanji conversion processing module Step 310: Separation position generation processing module Step 311: Kanji reading restoration module Step 312: Range setting processing module Step 313: Separation position selection key determination module Step 314: Mode setting key determination module Step 316: Automatic marker movement setting module Step 318: Automatic marker Moving time interval setting module Step 319: Corresponding delimiter conversion candidate output processing module

[Kana-Kanji conversion processing example 1] Here, FIG.
The display example 1 will be described. In FIG. 3, when the kana character string "ko" is input from the input processing unit 1 as shown in FIG. 4, the control unit 5 determines whether this is a kana character string (step 301), and the kana character string is displayed. Therefore, the conversion target character is stored in the storage unit 4, and the result is output and displayed on the display unit 8. Similarly, the kana character string shown in the display example 1 of FIG. 4 is processed. When the character string "here is Ishaga" is input and the key for conversion (the same as the homophone selection key) is pressed here, the input processing unit 1 determines whether the key is for conversion (step 302), the key pressing time determination unit 2 measures the time the key is pressed (step 303).

It is judged whether or not the key is pressed for a predetermined time or longer (step 304). If it is not longer than the fixed time, the Kana-Kanji conversion unit 6 is activated, and the delimiter sequence generation unit 7 stores candidates for different delimiters. At the same time, the candidate for the delimiter position with the highest priority generated by the kana-kanji conversion unit 6 is displayed on the display unit 8. The result is shown in FIG.
If the key press time determination unit 2 determines that the time is longer than a certain time (step 304), the key state detection process (step 305) moves the marker indicating the break position as the process when the conversion key is continuously pressed. Then, while the key is continuously pressed, the movement of the marker is performed at a slow fixed cycle, and the marker is sequentially moved to different positions (step 307).

When the key is turned off at the desired delimiter position (step 306), the first candidate output process of the conversion candidates corresponding to that position is performed (step 319). The result is shown in FIG. How the movement of the marker indicating the break position moves until the desired break position is selected is shown in FIG. The position of the break position is shown at the time when the first conversion key is pressed, and the current position of the marker is clearly indicated by a different conspicuous display.

FIG. 9 is a detailed block diagram of the key pressing time determination unit 2. In FIG. 9, when a key is pressed, a key code is generated, this key code is compared with the stored code of the comparison key code, and if they match, the time count is performed for the set number of times and the key is pressed for a certain time. Detects if it is pressed. Although not shown in FIG. 4, in order to make the delimiter position easy to understand, it may be possible to display it not by an overline but by another triangular mark or by changing the width of the overline.

The key used for conversion in the above description is a key for selecting a conversion candidate and a conversion next candidate (same word), and is not limited to the key name. In addition, as a method of outputting candidate strings with different break positions, the first conversion is only displaying the first priority candidate, and when the key is released and then pressed continuously, the position of the candidate with different break positions is displayed. To move the marker in sequence to select, or when the character string to be converted is input and the conversion key is held down without being released once, the first delimiter candidate is displayed and the marker is moved from that state to the next. The method of moving to the candidate of can be considered. Therefore, one conversion key can be used to select conversion candidates having different homophones and different delimiter positions. In addition, since the first conversion is limited to displaying the delimiter position and only the first conversion candidate, it is not necessary to display unnecessary conversion next candidates. Can be easily selected.

[Kana-Kanji conversion processing examples 2 and 3] Here, description will be given based on the display example 2 of FIG. In the above Kana-Kanji conversion processing example 1, when the conversion key is held down,
If there are two or more delimiter positions on one conversion candidate (Kanji) when displaying markers indicating delimiter positions one after another at fixed time intervals, the Kanji is restored to the reading information and the marker display is performed. It is possible to select conversion candidates having different positions. When the conversion target character string is input from the input processing unit 1, the control unit 5 sequentially stores this as the conversion target character string in the storage unit 4. When the conversion target character strings “here kimono” are input, these are stored in the storage unit 4 as the conversion target character string by the above-described processing, and the result is displayed on the display unit 8.

When a key for conversion is pressed in this state (step 302), it is determined whether or not there is a character string to be converted. In this case, there is a character to be converted, so the kana-kanji conversion unit 6 and the delimiter position generation unit 7 Displays the first conversion target character string. In addition to this, as shown in FIG.
The delimiter position is displayed with an overline above the converted character. In this state, it is determined whether or not the key for conversion has been pressed for a certain time or longer (step 304), and if the key has been pressed for a certain time or longer, the marker indicating the break position moves in a fixed cycle. Fig. 5 shows the movement of the marker on the display screen.
Shown in. As shown in Fig. 5, the marker is "footwear".
When you come onto the "shoes" of the
"Footwear" is replaced with the reading "haki" (step 31)
1).

FIG. 10 is a detailed block diagram of the reading / restoring unit 10. The reading / restoring unit 10 first searches the reading / writing correspondence table by the reading / writing correspondence table searching means, and searches for the corresponding kanji, here, the reading "haki" of "shoes" of "footwear", and the number of characters is 2, And the character width of the display is calculated and stored by the character width calculation means (character spacing calculation unit) from the number of read characters. Based on this information, the display unit 8 corrects the Kanji notation and displays the width of the read character so that it fits within the display width of the "sho" that was initially displayed, and the separation position at which the display does not expand or contract. Offers ease of selection. When the key for converting and selecting a homophony is kept pressed, the marker continues to move at the delimiter position at a constant cycle and when the marker comes to the desired position (step 306), the display example of FIG. 5 is displayed. This is performed by the corresponding delimitation conversion candidate output process (step 319).

In the above description, when there are two delimiter positions in one Kanji, the Kana-Kanji conversion processing example 2 is re-read and displayed, and the display width of the Kanji that was displayed first is the reading character. Displayed in is Kana-Kanji conversion processing example 3. Therefore, when two delimiter positions may occur on one conversion candidate (kanji), the conversion candidate can be changed to reading information and the delimiter position can be clarified when conversion is corrected. In addition, since the restored input kana character string is displayed with the character width changed so as to fit within the character spacing of the original candidate, the delimiter position included in the restored reading information is easy to see and selection is facilitated.

[Kana-Kanji conversion processing example 4] Here, FIG.
The display example 3 will be described. The mode setting unit 3 or the state of the mode set by default is controlled by the control unit 5.
When the automatic mode is set (step 312) and the delimiter position selection key is pressed at the position where the marker is present, the conversion result of the desired delimiter position is displayed. If automatic marker movement is set, the conversion key is pressed after the conversion target character string is input, and the kana-kanji conversion processing (step 309),
When the delimiter candidate generation process (step 310) and the kanji reading restoration process (step 311) are executed, the display of FIG. 6 is performed.

In this state, the marker moving unit 9 is activated by the control unit 5. The display screen at this time is shown in FIGS. The marker moves in a fixed cycle. When the marker comes to the desired break position and the break position selection key is pressed (step 313), it is determined whether the marker movement is automatic or manual, and since it is automatic, the corresponding break conversion candidate output process is performed. (Step 319), the result is displayed. FIG. 6 shows the conversion result in the case where the break position selection key is pressed when the marker comes to the “medicine” of the desired break position “dentist”. Therefore, when the marker is set so as to automatically move for each delimiter position in a fixed cycle and the input character string is converted by the conversion key, the marker moves until the desired delimiter position is selected by the delimiter position selection key. Then, at the same time when the delimiter position is selected, the candidate corresponding to the delimiter position can be converted and corrected.

[Kana-Kanji conversion processing example 5] Here, FIG.
The display example 4 will be described. The mode setting unit 3 or the state of the mode set by default is controlled by the control unit 5.
When the automatic mode is set (step 312) and the homophone selection key is pressed at the position where the marker exists, the next candidate or the previous candidate of the conversion result at the desired break position is displayed. To do. If automatic marker movement is set, the conversion key is pressed after the conversion target character string is input, and kana-kanji conversion processing (step 309) and delimiter candidate generation processing (step 3).
10) When the Chinese character reading restoration processing (step 311) is executed, the display of FIG. 7 is performed.

In this state, the marker moving unit 9 is activated by the control unit 5. The display screen at this time is shown in FIGS. The marker moves at regular time intervals. When the homophone selection key is pressed when the marker is at the desired break position (step 302), it is determined whether the marker movement is automatic or manual (step 308). The next candidate or the previous candidate is selected (step 312), and the result is displayed. FIG. 7 shows the conversion result when the homophone selection key is pressed when the marker comes to the first "ko" of the desired break position "here". Therefore, when the marker is set so as to automatically move at each delimiter position in a fixed cycle and the input character string is converted by the conversion key, the marker moves until the desired delimiter position is selected by the homophone selection key. Then, at the same time when the delimiter position is selected, the clause corresponding to the delimiter position can be converted into a homophone word candidate.

[Example of Marker Setting Processing] Here, description will be given based on a display example of the setting screen of the present invention shown in FIG. When the keys for conversion and selection of homophones are kept pressed, the moving speed of the marker indicating the break position can be set on the marker setting screen. Also, it is possible to set the automatic / manual mode to automatically move the marker after the conversion key is pressed, or to move the marker when the conversion or homophone selection key is held down. It is a thing.

For example, in the former mode setting, when it is desired to sequentially move the marker for each break position at a cycle of 1 second, a setting screen for setting the moving speed of the marker indicating the break position is displayed as shown in FIG. This is possible by inputting the designated number 1 in the field of N seconds. It is also possible to set the speed slower or faster than the current set value. In this case, it is conceivable that the marker is output on the screen at a blinking cycle or the like so that the marker can be selected and set. The latter automatic / manual setting of marker movement can also be selected and set from the setting screen display (guidance display) shown in FIG.

When the mode setting key is pressed from the input processing unit 1 (step 314), the control unit 5 determines whether the mode setting key is set. If it is the mode setting key, the mode setting unit 3 sets the time interval setting. Is determined (step 317), and if it is time interval setting, time interval setting processing is performed (step 318). As shown in FIG. 8, when the mode setting key is pressed, the display screen displays the setting screen of "movement speed setting of break position marker" for selecting the moving speed of the marker indicating the break position. In the mode setting for setting the movement of the marker shown in FIG. 8 to either automatic or manual, the selection setting is performed by the same setting screen display (guidance display). Therefore, it is possible to set the automatic / manual mode on the setting screen whether the marker indicating the delimiter position is automatically moved at a fixed time interval, for example, when the conversion key is continuously pressed.
Further, the moving speed (cycle) of the marker can be adjusted to the optimum operation speed of the user.

[0053]

According to the present invention, the following effects can be obtained. (1) It is easy to select a desired candidate by displaying where the break position is. (2) It is possible to select conversion candidates having the same phoneme and different delimiter positions with one conversion key. By holding down the key, you can select candidates with different break positions, and you do not need to press the key again and again, which improves usability. (3) In the first conversion, since only the delimiter position and the minimum conversion candidate of the first rank are displayed, unnecessary conversion next candidates need not be displayed, and even if the number of candidates is large. A desired candidate can be easily selected. (4) When two delimiter positions may occur on one conversion candidate (kanji), it is unclear if the delimiter position is in the kanji notation, but read the conversion candidate when correcting the conversion. Since the information is changed to information, the delimiter position can be clarified, and the delimiter position can be accurately selected. (5) Furthermore, since the restored input kana character string is displayed with the character width changed so that it fits within the character spacing of the original candidate, the displayed character does not expand or contract to the left or right, and the marker moves periodically. However, since the delimiter position does not move, the delimiter position included in the restored reading information is easy to see and selection is easy. (6) When the input character string is converted by the conversion key, the marker can be set so as to automatically move at each delimiter position at a fixed cycle in advance, and the marker is set until the desired delimiter position is selected by the delimiter position selection key. It is possible to move, and at the same time when the break position is selected, the candidate corresponding to the break position can be converted and corrected. Since the marker indicating the break position is automatically moved, it is not necessary to provide a special key for moving the marker. In addition, the marker movement key does not have to be pressed many times, which is convenient. (7) When the input character string is converted by the conversion key, the marker can be set so as to automatically move in advance at each delimiter position in a constant cycle until the desired delimiter position is selected by the homophone selection key. It is possible to move and select a delimiter position, and at the same time, convert a phrase corresponding to the delimiter position into a homophone word candidate. Since the marker indicating the delimiter position is automatically moved, when the conversion or homophone selection key is pressed, the homophone candidate at the position of the marker can be selected and the cursor movement key moves to the corresponding phrase. It is easy to use because it does not need to be performed. (8) Whether the marker indicating the delimiter position is automatically moved at a fixed time interval or, for example, when the conversion key is continuously pressed, automatic / manual mode setting can be performed on the setting screen. Further, the moving speed (cycle) of the marker can be set according to the optimum operation speed of the user. Even when selecting a homophone with a normal conversion key, the speed with which the key is pressed varies depending on the user. That is, it is possible to improve usability by setting the moving speed of the marker according to the user's preference. The timing of releasing the key pressed for a certain period of time has an advantage that it can be determined by the user's preference. By allowing the marker movement to be set automatically / manually, it is possible to expand the user's choice of usage methods.
