DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device for converting characters displayed on a display screen.

[0002]

SUMMARY OF THE INVENTION According to the present invention, a transparent touch panel is provided on a display screen of a display means, and when an unconverted kana character is touched through the transparent touch panel, the unconverted kana character is delimited by the kana character as a delimiter. By converting a character string into kana-kanji characters, desired document contents can be quickly obtained.

[0003]

2. Description of the Related Art Conventionally, in a kana-kanji conversion device, not only input of document data, but also position designation on a display screen,
Also, instructions of various processing contents are also performed by individual keys on the keyboard.

[0004]

Therefore, even if the conversion is performed in a batch for each sentence, the conversion candidate is not the desired one, and when re-conversion is desired, the cursor at the end of the sentence at that time is moved by moving the cursor. By continuing to hold down the key, it was necessary to move to the position of the conversion candidate, and then instruct the conversion to the next candidate using the next candidate key or the like.
In addition, despite the fact that all of the candidates have been converted, the desired result cannot be obtained, and it is often the first time that the user notices that the segment break is incorrect. In that case, move the cursor further. , The user must designate a desired phrase break and operate a predetermined key to instruct kana-kanji conversion processing with the cursor position as the break of the phrase, which requires a complicated operation. In other words,
The desired document content could not be obtained quickly. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to quickly obtain desired document contents.

[0005]

The means of the present invention are as follows. Display means for displaying character string data including an unconverted character string on a display screen; detecting means for detecting a display position arbitrarily designated on the display screen; and First conversion processing means for executing a conversion process on a partially unconverted character string corresponding to the indicated display position when an instruction for a display position corresponding to any of the character positions is detected; If the detection means detects an indication of a display position other than the unconverted character string, a second conversion for executing a conversion process on all unconverted character strings displayed on the display screen And processing means.

[0006]

The operation of the means of the present invention is as follows. When an arbitrary display position is indicated on the display screen displaying the character string data including the unconverted character string, the specified position is detected by the detecting means and corresponds to any character position on the unconverted character string. When the indication of the display position is detected, the conversion process is performed on the partially unconverted character string corresponding to the indicated display position. On the other hand, when an indication of a display position other than the unconverted character string is detected, the conversion process is performed on all the unconverted character strings displayed on the display screen.

FIG. 1 is a functional block diagram of the present invention, showing a schematic diagram of the flow from input means to conversion means.

First Embodiment Hereinafter, a first embodiment will be described with reference to FIGS.

[0008] Configuration Figure 2 is a block diagram of a Kana-Kanji converting apparatus. This kana-kanji conversion device generates grammatical candidates by analyzing the grammar of the character data input from the key input unit 1 under the control of the CPU 2, and refers to the conversion dictionary 3 based on the lexical candidates. hand,
Various processes such as kana-kanji conversion are performed, and the results of the processes are stored in the document memory 4 as document data, displayed on the display unit 5, and printed by the printing unit 6. Further, by touching a transparent touch panel 5A, which will be described later, the instruction of the re-conversion processing and the specification of the delimiter position of the Kana character data string to be re-converted are performed at the same time.

The key input unit 1 includes a kana character key 1A for inputting kana character data, a conversion key 1B for instructing to display a kana-kanji conversion result for the input kana character data string, and a kana-kanji conversion result for the kana-kanji conversion result. Has a key, such as a determination key 1C, for instructing the user to confirm. The kana character data string input by operating the kana character key 1A is
The data is temporarily stored in the input buffer 7. And CPU2
Under the control of grammar, the grammatical analysis is performed on the kana character data string, and the kana-kanji conversion processing is performed for each bunsetsu, and the processing result is stored in a candidate buffer as a conversion candidate. 8 is stored. At this time, the reading length, the candidate length, and the candidate level of the conversion candidate for each clause in the candidate buffer 8 are recognized and stored in the management buffer 9. Note that the reading length indicates the number of sounds when the contents of the corresponding conversion candidate are pronounced, that is, the number of characters when represented by kana characters, and the candidate length indicates the number of characters including kana characters and kanji of the conversion candidates. , Candidate level indicates the priority of conversion (see FIG. 7). Then, when a confirmation instruction is given to the contents in the candidate buffer 8 by the confirmation key 1C,
The contents are stored in the document memory 4.

The display unit 5 displays the input kana character data string under the control of the CPU 2 together with a delimiter mark indicating a delimiter of a phrase, and displays kana-kanji conversion candidates based on the phrase. Is what you do. The display unit 5 includes a transparent touch panel 5A and a liquid crystal display unit 5B.
The transparent touch panel 5A is provided on the display screen of the liquid crystal display unit 5B. The transparent touch panel 5A has a structure in which a touch switch group made of a transparent member is arranged in a matrix on a flexible transparent film so that the display contents of a liquid crystal display unit 5B thereunder can be seen. It has become.

The sampling circuit 10 periodically samples one touch switch at a time. The touch coordinate detecting unit 11 first turns on / off the touch switch sampled by the sampling circuit 10.
Check the off state. When the sampled touch switch is on, the coordinate data is output to the CPU 2. Then, the address data and the like on the document memory 4 of the character displayed at the position corresponding to the turned on touch switch are calculated under the control of the CPU 2 and stored in the document address buffer 12.

FIG. 3 is an external view of a kana-kanji conversion device according to this embodiment. As illustrated, the display unit 5 and the other components (main body side) are formed on separate housings,
These are electrically connected by a flat cable 100 and are configured to be spread on a desk. Therefore, it is easy for the left hand to specialize in the re-conversion instruction to the next candidate by the transparent touch panel 5A, and for the right hand to specialize in data input and the like by the key input unit 1. of course,
It is also possible to input data from the key input unit 1 using both hands, and then instruct the re-conversion to the next candidate by touching the transparent touch panel 5A with the left hand.

The housing on which the display unit 5 is formed can be folded in two to form a large screen, and is superimposed on the key input unit 1 on the main body side in the folded state. Thereby, it is configured to be compact and easy to carry.

[0014] Operation Next, with reference to FIGS, the operation of this embodiment will be described.

Now, it is assumed that a kana character data string "There is today" is input from the key input unit 1. Then, the contents are stored in the input buffer 7 (step S41 in FIG. 4). Then, CP
U2 indicates that a kana character string in the input buffer 7 that has not been subjected to grammatical analysis processing, that is, a phrase recognition processing, is 1
It is determined whether or not it is zero or more characters (step S4).
2). As a result, if the number of characters is less than 10, the processing is terminated as it is, and the processing waits until the number of characters becomes 10 or more.

On the other hand, if the number of characters is 10 or more, grammatical analysis is performed from the beginning of the unprocessed kana character string to divide it into clauses, and cut out as clause candidates (conversion units) (step S).
43). Then, a phrase candidate is displayed on the unprocessed kana character string displayed on the liquid crystal display unit 5B in such a manner that a delimiter mark such as a broken line shown in FIG. It is displayed on the display unit 5B (step S44).

Next, a kana-kanji conversion process is performed for each phrase candidate with reference to the conversion dictionary 3, the conversion result is stored in the candidate buffer 8 as a conversion candidate, and the reading length, candidate length, candidate level Is stored in the management buffer 9 (step S45: see FIG. 7A).

Looking at the displayed phrase candidates (delimiter marks), there is a phrase candidate different from the desired one,
When it is desired to perform kana-kanji conversion with another phrase candidate (conversion unit), a kana character at a desired break position may be touched via the transparent touch panel 5A. For example, in order to create a document "Today's company ...", ""
As shown in (a), if the phrase is "Today: ...", it is expected to be incorrectly converted to "A church member ...". To get from the beginning, the last "U" in the phrase "Kyoto"
Just touch.

That is, when the transparent touch panel 5A is touched, first, touch coordinates are detected by the coordinate detecting section 11 and output to the CPU 2 (step S51 in FIG. 5).
Therefore, the CPU 2 determines whether or not the touch is on a Kana character as a phrase candidate (step S52). As a result, if the touch is on a kana character as a phrase candidate, the kana character corresponding to the touched position is specified as a delimiter position (step S53), and a phrase candidate containing the kana character (in the above example, “Kyokaisha”) ")" To the character string from the head of the touch position to the kana character at the touch position ("Kyo" in the above example) is subjected to kana-kanji conversion processing (step S5).
4).

Then, as shown in FIG. 6B, a delimiter mark is displayed next to the kana character at the touch position (step S55). Next, the kana-kanji conversion result in step S54 is stored in the candidate buffer 8 as a conversion candidate, and the reading length, the candidate length, and the candidate level are stored in the management buffer 9 (step S56). Then, the grammar analysis is performed again for all the kana character strings after the delimiter mark corresponding to the touch position, re-recognition of the segment break, re-conversion based on the re-recognition, re-display of the delimiter mark, the candidate buffer 8, and the management buffer. Is stored (step S5).
7). As a result, for example, the contents of the candidate buffer 8 and the management buffer 9 shown in FIG. 7A are rewritten as shown in FIG. 7B. In other words, "at church" is retransformed as "at work today."

In step S52, when it is determined that the touch is not a touch on a phrase candidate, that is, as a kanji character or a part of a kana kanji conversion candidate, such as "de" in "at a teaching company". When the kana character is touched, the process ends.

When all of the phrase candidates relating to the change displayed in this way are desired, FIG.
By operating the execution key 1B as shown in FIG.
The kana-kanji conversion candidate corresponding to the phrase candidate is read from the candidate buffer 8 and displayed on the liquid crystal display unit 5B.

As described above, with a single touch via the transparent touch panel 5A, processing is performed assuming that both the designation of the delimiter position of the kana character data string to be reconverted and the instruction of the reconversion processing have been performed. You. That is, a single touch on the transparent touch panel can obtain kana-kanji conversion candidates based on other phrase candidates. Also,
As in this embodiment, a kana / kanji conversion candidate is not immediately displayed, but a kana character data string is temporarily added with a segmentation mark to display the kana / kanji character string, thereby checking in advance whether there is an erroneous conversion. Can be. Therefore, the next candidate for the same phrase candidate, which is often used by beginners, is displayed, and the desired one cannot be obtained.At that point, the user first notices a mistake in the phrase segmentation and instructs conversion at another segmentation. It is not necessary to perform useless operations such as performing Further, as is clear from FIG. 6, the cursor does not move when touching to specify another delimiter position, so that when inputting the kana character data is continued, the cursor is returned to the end of the sentence. Operation is unnecessary.

[0024]

Second Embodiment Next, a second embodiment will be described with reference to FIGS.

The difference between the second embodiment and the first embodiment is that, in the second embodiment, as in the first embodiment, the grammar analysis and the display of the delimiter mark are automatically performed by inputting the kana character data string. As shown in FIG. 8, the kana-kanji conversion process is executed for the first time by specifying the delimiter position of the conversion target without performing the kana-kanji conversion or the like.

Now, a kana character data string of "There is a character" is input from the key input unit 1, and the content is input to the input buffer 7, and FIG.
As shown in (a), it is assumed that the input data is displayed as it is without inserting a delimiter mark.

In this state, as shown in FIG.
Assuming that "U" is touched on the transparent touch panel 5A, first, the touch detection coordinates are detected by the coordinate detection unit 11 and output to the CPU 2 (step S91 in FIG. 9). Therefore, the CPU 2 determines whether or not the touch is on a Kana character (step S92). As a result, since the touch is on the Kana character, the Kana character “U” corresponding to the touch position is specified as a delimiter position (step S93).
Kana-Kanji conversion is performed for "Kyo" from the head "K" of the unconverted Kana character to the Kana character "U" at the touch position (step S94). At this time, as shown in FIG. 8B, the character string to be converted is underlined, so that it can be determined whether or not a touch error has been made. Next, the kana-kanji conversion result is stored in the candidate buffer 8 as a conversion candidate, and the reading length, the candidate length, and the candidate level are stored in the management buffer 9 (step S95).

Then, the conversion candidates are displayed in place of the kana characters to be converted (step S96). In this example, FIG.
As shown in (c), “today” is converted to “today. At this time, the conversion result is
A mark “outside 1” is added. Therefore, even when the conversion result includes a kana character, such as “Document is”, the next desired break position can be easily found.

If it is determined in step S92 that the touch is not a touch on a kana character, all unconverted kana characters are converted into kana-kanji characters (step S9).
7), and proceed to step S95. Therefore, when there is only one segment break in the input kana character data string, a desired document content can be quickly obtained by touching an arbitrary blank area.

The present invention is not limited to the above-described embodiment. For example, although the name of the invention is "Kana-Kanji conversion device", the invention is not limited to Japanese in which phonograms and ideograms are mixed. In a device that processes a document in another language, the present invention can also be applied to a case where an input phonetic character string is converted into an ideographic character.

[0031]

According to the present invention, on a display screen on which character string data including an unconverted character string is displayed, partial conversion is performed only on a desired partial character string of the unconverted character string. Whether the processing is performed or the entire conversion processing for all the unconverted character strings is automatically distinguished according to the designated operation position, and each corresponding conversion processing can be performed.
