2. Description of the Related Art In recent years, CPUs (Central Processing Uni
The processing capability of t) has been improved, and the processing speed of the character input device is also increasing. Along with this, demands for improving operability when inputting characters are also increasing.

Conventionally, when inputting a document using a character input device, if the same word or character string is input many times, the same input operation must be performed each time, which hinders improvement of workability. There was a problem. The following inventions have been disclosed in order to solve this problem.

The invention disclosed in Japanese Patent Application Laid-Open No. 57-150025 discloses that when a word or a phrase to be input by an operator is used before that in the same document, only a part of the word or the phrase is used. By calling and using the word or phrase by inputting it, the operation required for inputting can be reduced.

The invention disclosed in Japanese Unexamined Patent Publication No. 1-253079, when the operator inputs a handwritten pattern,
By outputting the fixed phrase character string associated with the handwritten pattern registered in advance, the operation required for input can be reduced.

In the invention disclosed in Japanese Patent Laid-Open No. 60-59421, every time the input kana information is converted to kana-kanji, the converted kanji or kanji-magic information is registered as a headword for kana characters. The kana character or kanji magic information is retrieved and output by giving the leading kana character and a conversion instruction.

Character input is performed by the CPU 1 executing a character input program. In addition, the inverse conversion unit 9 and the abbreviated conversion dictionary area 10
A detailed description of the above will be given later.

FIG. 2 is a flowchart showing the processing procedure of the character input device according to the first embodiment. 3 to 5
The flow chart shown in FIG. 2 will be described below with reference to the operation procedure shown in FIG.

First, the document edit screen is displayed on the display unit 4. As shown in FIG. 3A, the document edit screen includes a document data display window 12, a confirmed character string / candidate character string display window 13, a recognized character string display window 14, and a handwritten character input window 15. The document data stored in the storage unit 3 is displayed in the document data display window 12. Characters handwritten on the tablet by the operator using the pen are extracted by the input unit 5 and displayed in the handwritten character input window 15. The operator moves a cursor or the like to a character string input desired position of the document data displayed in the document data display window 12.
An example of the display is shown in FIG. Then, the operator inputs handwritten characters at a predetermined position on the tablet (S101). The handwritten character is displayed in the handwritten character input window 15. An example of the case where handwritten characters are displayed in the handwritten character input window 15 is shown in FIG.
It shows in (b).

The CPU 1 sends handwritten data to the handwritten character recognition unit 6 (data of the handwritten character shape).
Is instructed (S102). Handwritten character recognition unit 6
Compares the handwriting data with the shape data of the characters stored in the character data recognition dictionary 7 and converts them into kana or kanji characters. Then, the converted character data which is the recognition result is sequentially stored in the result storage area set in the storage unit 3, and the recognition result is displayed in the recognized character string display window 14 displayed on the display unit 4. An example of the display on the display unit 4 at this time is shown in FIG. If all handwritten data is converted into character data by the handwritten character recognition unit 6, the process proceeds to step S104 (S10).
3).

After converting the handwritten data into character data,
It is determined whether or not a horizontal line is input between the frames of the handwritten character input window 15. If no horizontal line is entered between the frames, it is determined that there is no special character (S104, YE
S), the process proceeds to step S117. If a horizontal line is entered between the frames, it is determined that there is a special character (S10
4, NO), and proceeds to step S105. Figure 3 (d) shows
An example of the display in the handwritten character input window 15 at this time is shown, and a horizontal line 16 is provided between the frames 15c and 15d.
Indicates that there is.

When the CPU 1 determines in step S104 that a horizontal line has been entered between the frames, it issues an instruction to recognize the special character to the special character recognition unit 8. The special character recognition unit 8 confirms the handwritten data entered in the frames on both sides of the horizontal line 16 (frames 15c and 15d in FIG. 3D), and inputs them in the frames 15c and 15d if the following conditions are satisfied. Recognizes the drawn characters and horizontal lines as one special character,
If the condition is not satisfied, it is regarded as not a special character (S1
05, NO), and proceeds to step S117.

(1) Frames (15c, 1) on both sides of the horizontal line 16
A horizontal line is entered in 5d).

(2) The horizontal lines in the frames (15c, 15d) and the horizontal lines between the frames are connected. (3) The length of the horizontal line in the frame (15c, 15d) is not less than the specified value.

FIG. 3E shows the length A of the horizontal line in the frame 15c.
And that the length B of the horizontal line in the frame 15d is equal to or greater than the specified value, and the horizontal line in the frame (15c, 15d) and the horizontal line 16 are connected. When it is recognized as a special character, character data (“-” (hyphen), which is a normal handwritten character recognition result in the frames (15c, 15d) on both sides,
Ignoring "-" (long sound symbol), "1" (1 of Chinese character, etc.), the process proceeds to step S107.

Frames (15c, 15) in which special characters are input
If a number is entered in the frame (15e) next to d), the number is stored in the register 2 in the CPU 1, and if no number is entered, 0 is stored in the register 2 (S).
107).

The CPU 1 displays the recognition result in the recognized character string display window 14 in the display section 4 (S108).
At the time of display, the special character and the number in the frame next to the special character are highlighted so that they can be distinguished from other characters. An example of the display in the recognized character string display window 14 at this time is shown in FIG.

If a character string is stored in the document data being processed in the storage unit 3 (S109, YES), the process proceeds to step S110, and if it is not stored (S109, N).
O), of the character strings recognized in step S103, the character string before the special character is set as the first candidate character string, and the process proceeds to step S117.

The CPU 1 searches for a character string in the document data stored in the storage unit 3, and searches for a character string identical to the character string before the special character. When the same character string does not exist (S110, NO), the character string prior to the special character among the character strings recognized in step S103 is set as the first candidate character string, and the process proceeds to step S117.

Further, when the same character string as the character string before the special character exists in the document data (S110, YE
S), the CPU 1 reads the number stored in the register 2. When this number is other than 0 (S111, NO), the total number of characters of the same character string in the detected document data and the character string following the same character string is the same as the number stored in the register 2. A character string is acquired (S112).
Then, the acquired character string is selected as one of the conversion candidates for handwritten characters.
It is stored in the storage unit 3 as a character string. When the document shown in FIG. 4A is stored as handwritten data in the storage unit 3, the character “target” exists in three places 18a to 18c in the document as shown in FIG. 4B. Since five characters including “target” are extracted, “new target”, “become target” and “quality of target” are extracted as conversion candidates. An example of the display at this time is shown in FIG.

Next, the character string of the conversion candidate of the handwritten character acquired in step S112 is displayed in the confirmed character string / candidate character string display window 13 in the display unit 4 (S).
113). Then, it is determined whether or not another identical character string exists in the document (S114). If there is another identical character string (S114, YES), the process returns to step S111 and the subsequent processes are repeated. If no other identical character string exists (S
114, NO), and proceeds to step S115.

When the register 2 is determined to be 0 in step S111 (S111, YES), the same character string in the detected document data to the delimiter such as a punctuation mark is acquired (S116). Then, the acquired character string is stored in the storage unit 3 as one character string that is a conversion candidate for handwritten characters. As document data in the storage unit 3, FIG.
When the document shown in is stored, “target is development of new product”, “target” and “in target quality improvement activity” are extracted as conversion candidates.

The operator selects a desired character string from the conversion candidates displayed in the confirmed character string / candidate character string display window 13 in the display unit 4 by the input unit 5, and selects the selected character string as the first character string. One candidate character string is set (S115).

The CPU 1 displays the first candidate character string on the top row of the confirmed character string / candidate character string display window 13 in the display unit 4, and displays the other candidates below it (S11).
7).

When the operator confirms the displayed first candidate character string and confirms it with this character string (S118, YE
S), and a confirmation instruction is issued by the input unit 5. Also, the first
If the candidate character string is to be corrected (S118, NO),
Other candidates may be used as the first candidate character string, or the first candidate character string may be directly modified with a pen or the like to make corrections such as deleting the unnecessary character string and fixing the corrected character string ( S119). An example of the display before the correction at this time is shown in FIG. 5A, and an example of the display after the correction is shown in FIG. 5B.

Then, the confirmed character string is displayed at the cursor position shown in FIG. 4 (a), and the confirmed character string is inserted into the relevant portion in the document data stored in the storage unit 3 (S120). An example of the display at this time is shown in FIG.
It shows in (c).

As described above, when the same character as the handwritten character is present in the document data, the character string including the same character string is extracted, so that a character string having a large number of characters can be easily input. The workability of the operator is improved.
In addition, since handwritten characters are input, it is possible to directly input kanji, and it is possible to reduce the number of candidates that are searched for and extracted in the document data.

Further, since special characters are input by handwriting input, there is no need to perform any processing other than handwriting input during the process, and the workability of document creation is improved.

Further, since the number of characters of the candidate character string can be designated by handwriting after the special character input, it becomes possible to easily input a character string having a large number of characters only by handwriting input, and the workability is improved. To do.

[Second Embodiment] The configuration of the character input device according to the second embodiment of the present invention is the same as that of the first embodiment shown in FIG.
Since the structure is the same as that of the character input device in, detailed description will not be repeated. However, the inverse conversion unit 9 for converting a Kanji character not used in the first embodiment into a Kana character
Is used in the second embodiment.

FIG. 6 is a flowchart showing the processing procedure of the character input device according to the second embodiment. In the flowchart shown in FIG. 6, steps S101 to S120 are the same as the procedure described with reference to the flowchart in the first embodiment shown in FIG. 2, and therefore, redundant description will not be repeated.

If the document data exists in step S109 (YES in S109), it is determined whether or not the character string before the special character is a kana character (S20).
1). When the character string before the special character is a kana character (S201, YES), the process proceeds to step S202. An example of the display at this time is shown in FIG. If the character string before the special character is not a kana character (S201, N
O), the process proceeds to step S110, and the same process as the process described with reference to FIG. 2 is performed.

Next, of the character strings recognized in step S103, the character string before the special character is displayed as the first character string in the confirmed character string / candidate character string display window 13 in the display section 4.
It is displayed at the position of the hierarchy (top row) (S202). This character string is the first candidate character string. An example of the display at this time is shown in FIG.

The CPU 1 searches the Kana-Kanji character string in the document data stored in the storage unit 3. The number of characters detected at this time is the number stored in the register 2. When the value of the register 2 is 0, up to the delimiter such as a punctuation mark appearing after the character string is detected as the character string (S203). However, the character string to be detected is only the character string starting with the Kanji character. For example, in the case of the document data shown in FIG. 7C, if the value of register 2 is 5,
A character string of 5 characters starting from the Chinese character described in the left column of (d) is detected.

Then, the CPU 1 instructs the inverse conversion section 9 to
The first Kanji character of the detected Kana-Kanji character string is converted back into a Kana character string (S204). An example of this case is shown in FIG.
It is shown in the right column of (d).

When the kana character string inversely converted in step S204 matches the kana character string recognized in step S103 (S205, YES), the process proceeds to step S207. When the kana character string inversely converted in step S204 does not match the kana character string recognized in step S103 (S205, NO)
Determines whether or not the leading kanji character of the kana-kanji character string has another reading, and if there is another reading (S206, YE
S) and returns to step S205 to repeat the same processing. If another reading does not exist (S206, NO), the process proceeds to step S209.

Next, the leading kana character string of the kana-kanji character string converted into the kana character string in step S204 is returned to the original kanji character before the reverse conversion (S207).

The kana-kanji character string is displayed on the display unit 4.
It is displayed at the position of the second layer (below the first layer) in the candidate character string display window 13 (S208). As shown in FIG. 7D, the reading of the first Kanji character is “Moku”, “becomes target”, “target quality”, and “target standing” correspond to the candidate character strings. An example of the display at this time is shown in FIG.

It is determined whether or not there is an unprocessed character string in the Kana-Kanji character string retrieved in step S203 (S209). If there is an unprocessed character string (S20
(9, YES), and returns to step S204 to repeat the above-described processing. If there is no unprocessed character string (S209, N
O), the document data is searched, and if the same kana character string as the kana character string recognized in step S103 does not exist (S210, NO), the process proceeds to step S117.
When the same kana character string as the kana character recognized in step S103 exists in the document data (S2
(10, YES) is displayed at the position of the second layer in the confirmed character string / candidate character string display window 13 in the display unit 4.
The number of characters detected at this time is the number of characters stored in the register 2. When the value of the register 2 is 0, the delimiters such as punctuation marks appearing after the kana character string are detected as the character string. Then, the process returns to step S210, and the same processing is repeated.

As described above, in addition to the effects described in the first embodiment, the character input device according to the second embodiment inputs the reading even when the assumed kanji cannot be written correctly when inputting by handwriting. By doing so, it becomes possible to input a character string containing the kanji in the document data, and the workability at the time of document creation is improved.

[Third Embodiment] The configuration of the character input device according to the third embodiment of the present invention is the same as that of the first embodiment shown in FIG.
Since the structure is the same as that of the character input device in, detailed description will not be repeated. However, the inverse conversion unit 9 for converting a Kanji character not used in the first embodiment into a Kana character
And the shortening conversion dictionary area 10 set in the storage unit 3 is used.

FIG. 8 is a flowchart showing the processing procedure of the character input device according to the third embodiment. In the flowchart shown in FIG. 8, steps S101 to S108 and steps S117 to S119 are the same as the procedure described with reference to the flowchart in the first embodiment shown in FIG. 2, and therefore, redundant description will not be repeated.

First, while the document data stored in the storage unit 3 is being displayed in the display unit 4, the CPU 1 searches the Kana-Kanji character string in the document data stored in the storage unit 3 (S301). ). The number of characters in the kana-kanji character string detected at this time is a specified value or a preset value. An example of a kana-kanji character string detected when the document data stored in the storage unit 3 is the document data shown in FIG. 9A is shown in the left column of FIG. 9B. However, in FIG.
(B) shows a case where the number of characters in the kana-kanji character string is set to five.

A number is added to the detected kana-kanji character string, and the kana-kanji character string in which the kana-kanji character string number and the relative position in the document data are detected in the shortening conversion dictionary area 10 in the storage unit 3. Is stored together with (S30
2). An example of data stored in the shortening conversion dictionary area 10 at this time is shown in the left column of FIG. 9B.

The CPU 1 instructs the inverse conversion unit 9 to convert the first kanji of the detected kana-kanji character string into a kana character, and this converted kana character is relative to the kana-kanji character string in the shortened conversion dictionary area 10. It is stored following the position data. At this time, if a plurality of readings are present in the leading kanji of the kana-kanji character string, the plurality of readings are stored together (S303). Then, the process proceeds to step S101,
The same processing as steps S101 to S108 of the character input device according to the first embodiment shown in FIG. 2 is performed.

Following the display of the recognition result in the recognized character string display window 14 in step S108, the character string before the special character in the recognized character string is the fixed character string / candidate character string in the display unit 4. It is displayed at the position of the first layer of the display window 13. This character string is set as the first candidate character string (S304).

When the character string before the special character in the recognized character strings is a kana character string (S305, YE
S) proceeds to step S306, and if it is not a kana character string (S305, NO), proceeds to step S310.

In step S306, the character string data in the shortening conversion dictionary area 10 is searched, and if a kana-kanji character string having the same kanji character at the head as the recognized kana character string is detected (S306, YES), , Step S3
If no kana-kanji character string in which the kanji of the same reading as the recognized kana character string is at the head is detected (S30).
6, NO) proceeds to step S313.

When a kana-kanji character string having the same kanji at the head is detected in step S306, the detected kana-kanji character string is set as a conversion candidate character string (S30).
7). Then, this conversion candidate character string is displayed at the position of the second layer of the confirmed character string / candidate character string display window 13 in the display unit 4 (S308). An example of the display at this time is shown in FIG.

In the kana-kanji character string in which the first kanji is converted into the kana character in step S303, if there is another kanji with the same reading as the recognized kana character string (S309,
(YES), and returns to step S307 to repeat the process. If there is no other kanji that has the same reading as the recognized kana character string (S
309, NO), and proceeds to step S313.

On the other hand, if the character string recognized in step S305 is not a kana character string (S305, NO),
Search the Kana-Kanji character string in the short conversion dictionary area 10,
When a kana-kanji character string having the same character string at the beginning as the recognized character string is detected (S310, YES), the detected kana-kanji character string is displayed in the confirmed character string / candidate character string display window 13 of the display unit 4. Display at the second level (S
311). An example of the display at this time is shown in FIG.
Then, the kana-kanji character string in the abbreviated conversion dictionary area 10 is searched, and if another kana-kanji character string having the same character string as the recognized character string at the beginning exists (S312, YE).
S) returns to step S311 and repeats the processing. When there is no other character string including the recognized character string (S31
2, NO) proceeds to step S313.

In step S 313, the operator looks at the conversion candidate character string displayed in the confirmed character string / candidate character string display window 13 in the display unit 4 and selects a desired character string. A character string to be one candidate character string is designated (S313). Steps S117 to S described using the flowchart in the first embodiment shown in FIG.
After performing the processing of 119, the confirmed character string is shown in FIG.
The fixed character string is displayed at the cursor position shown in (a), and the confirmed character string is inserted at the corresponding position in the document data stored in the storage unit 3 (S314). An example of the display at this time is shown in FIG. Then, the confirmed character string is stored in the shortening conversion dictionary area 10 and the process is terminated (S31).
5).

As described above, in addition to the effects described in the first embodiment, the character input device according to the third embodiment can input a character string that is not included in the currently processed document data. If the previously processed character string is registered in the shortening conversion dictionary area 10, the search becomes possible and the workability of document creation is further improved.

[Fourth Embodiment] The configuration of the character input device according to the fourth embodiment of the present invention is the same as that of the first embodiment shown in FIG.
Since the structure is the same as that of the character input device in, detailed description will not be repeated.

FIG. 11 is a flowchart showing the processing procedure of the character input device according to the fourth embodiment. In the flowchart shown in FIG. 11, steps S101 to S10
3 and S108 to S120 are the first embodiment shown in FIG.
Since it is the same as the procedure described using the flowchart in, the duplicated description will not be repeated.

The operator looks at the character string of the recognition result displayed in the recognized character string display window 14 in the display unit 4, and uses a pen, a tablet or the like to select the portion of the character string to be shortened and converted from the character string. It is specified by enclosing it using the connected input unit 5 (S401). An example of the display at this time is shown in FIG.

The CPU 1 sets the character string designated by the input unit 5 as a search character string for shortening conversion (S402). An example of the display at this time is shown in FIG.

Next, the character number designation window 19 and the message 20 are displayed in the display unit 4 to prompt the operator to designate the length of the character string when searching for the character string (S403).

As described above, in addition to the effects described in the first embodiment, the character input device according to the fourth embodiment specifies the shortening conversion function and the search target by enclosing the search target character string. It is possible to specify a character string at the same time, which further improves the workability of document creation.

[Fifth Embodiment] The configuration of a character input device according to a fifth embodiment of the present invention is the same as that of the first embodiment shown in FIG.
Since the structure is the same as that of the character input device in, the detailed description will not be repeated.

FIG. 13 is a flowchart showing the processing procedure of the character input device according to the fifth embodiment. In the flowchart shown in FIG. 13, steps S101 and S10.
2 and S107 to S120 are the first embodiment shown in FIG.
Since it is the same as the procedure described using the flowchart in, the duplicated description will not be repeated.

The handwritten character recognition unit 6 compares the input handwritten data with the shape data of the characters stored in the character data recognition dictionary 7 and converts them into kana or kanji characters (S501).

The input width of the handwritten character is measured, and the register 2
The handwritten character input position 21 (FIG. 14A) in the display unit 4 is stored in the recognition result storage area allocated in the storage unit 3 in order to store the converted character data.
Display the recognition result in (). An example of the display at this time is shown in FIG.

If the conversion target character of the input handwritten data is not a horizontal line (S503, NO), step S50
5, the ordinary recognition process is performed on the input handwritten data (S505), and if there is unprocessed handwritten data (S506, YES), the process returns to step S501 to repeat the process. If there is no unprocessed handwritten data (S506, NO), the process proceeds to step S117. If the conversion target character of the handwritten data is a horizontal line in step S503 (S503, YES), the length of the horizontal line is compared with the widths of other characters stored in the register 2, and a prescribed ratio (for example, double) or more is compared. (S504, YE
S), the special character recognizing unit 8 recognizes this horizontal line as a special character and performs the processing from step S107. If it is smaller than the specified ratio (S504, NO), the horizontal line is regarded as a normal horizontal line and the process proceeds to step S505.

As described above, in addition to the effects described in the first embodiment, the character input device according to the fifth embodiment allows easy input of special characters even when there is no input frame when inputting handwritten characters. Therefore, it is not necessary to perform processing other than handwriting input on the way, and the workability of document creation is improved.
