Abstract

PURPOSE:To attain close writing conversion with a simple operation by operating a cursor control key to shift a cursor for each character or each word. CONSTITUTION:A character cursor 40 displayed in an input character string display area 46 equals an underline put under a single character; while a word cursor 48 shown in a conversion character string display area 44 displays with inversion the characters forming a single word. A character string obtained after conversion, i.e., the result of conversion is displayed in the area 44. While 'auto-KANA (Japanese syllabary)/KANJI (Chinese character)' showing that a conversion action mode is equal to an automatic KANA/KANJI conversion mode is displayed in the first half of the area 46. Then the input character string and the cursor 40 are displayed on the brackets 47 in the second half of the area 46. Here a character string obtained after conversion is called 'conversion character string'.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character string processing device, particularly a character string processing device that derives a corresponding string from an input string, such as a Japanese word processor or a translation machine. This paper relates to a display cursor control method in solid kana-kanji conversion.

For example, in the ``kana-kanji conversion'' method widely used in Japanese word processors, a converted string is generated from an input string in units of words or segments. this is,
Since word processing such as confirmation and correction of Kanji words is performed on a word-by-word or segment-by-segment basis, there is a drawback that the frequency of operator intervention, that is, the frequency of keystrokes, is high.

On the other hand, in the so-called "solid writing conversion" method, the word breaks are extracted and converted to kanji for a string of reading characters input continuously in kana or romaji, and therefore the processing of the string is done in writing. Since it is a unit, it has the advantage of being simple to operate.

- When inputting text using the keyboard, you may want to modify the input string due to input errors or changes of intention. Such corrections or modifications are required to be easily performed by simple operations. Furthermore, when performing the solid writing conversion operation, it is required to be able to clearly understand and handle the Δ units and pronunciations of words.

1-" It is an object of the present invention to provide a display cursor control method that eliminates the drawbacks of the prior art and allows solid writing conversion to be performed with a simple operation.

In order to achieve the above object, the present invention provides an input means having a reading character key and a cursor control key for inputting a first character string in a reading character notation, a display means for displaying characters, and a display means for displaying characters. control means for sequentially converting the first character string into a corresponding second character string;
When the first character string is input by the input means, it is displayed on the display means and sequentially converted into the character string of cylinder 2, and when the cursor control key is operated, the word included in the second character string is selected. This feature is characterized in that the display means displays a display that instructs the user. Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

Referring to FIG. 1, an embodiment in which the present invention is applied to a Japanese word processor is shown in a conceptual functional block diagram. As shown in the figure, this embodiment uses an input device 20 such as a keyboard, a display device 22, and a kana-kanji conversion algorithm 24 that executes solid kana-kanji conversion by referring to a conversion dictionary 2B such as a kanji dictionary or a grammar dictionary. and has.

In this embodiment, the input bag R20 has a reading character key for inputting reading (phonetic) characters such as kana or alphabet, and various cursor control keys. The cursor control key is used to control the display screen 38 (second
A "cursor forward" key 50 (FIG. 4) moves the cursor 40 (FIG. 3) forward displayed in the input character string display area 46 (FIG. 4), and a "cursor back" key 52 (FIG. (Fig. 4) and the word display cursor 48 displayed in the converted character string display area 44 (Fig. 4).

key 56, the "Beginning of Sentence" key that moves the word cursor 48 to the beginning of the sentence in the converted character string display area 44, and the "Beginning of Sentence" key that moves the word cursor 48 to the end of the sentence in the converted character string display area 44.
It consists of the "End of Sentence" key. Of course, the input device 20 has other function keys, but since these are not directly relevant to understanding the present invention, their explanation will be omitted. Note that in this specification, the term "r character" includes not only kana or alphabet letters, but also punctuation marks and other symbols.

The display device 22 may be a CRT character display device, for example.
The reading character string input into this system and the character string resulting from Kana-Kanji conversion are visually displayed. The display screen 38 consists of areas, or lines, in which a plurality of characters are displayed in a plurality of horizontal rows, and in this embodiment, it consists of a total of 24 lines. Of these, the hatched part 36 is
As shown in FIG. 3, it consists of a converted character string display area 44 on the 22nd line and an input character string display area 46 on the 24th line. The remaining area 37 is a display work area where processing such as editing and calculation is performed on the data that has undergone kana-kanji conversion.

Character cursor 4 displayed in input character string display area 46
In this embodiment, 0 is an underline "-" located below a single character, and the word cursor 48 displayed in the converted character string display area 44 displays characters constituting a single word in reverse video. It is something to do.

The converted character string display area 44 displays a converted character string that is a conversion result. In addition, input character string display area 46
In the first half of the screen, an indication that the conversion operation mode is automatic kana-kanji conversion mode, ``My Kana/Kanji'' is displayed, and in the second half, the input character string and the cursor 4 are displayed inside the parentheses [ ] 47.
0 is displayed. Note that herein, the character string after conversion will be referred to as a converted character string.

The kana-kanji conversion algorithm 24 is a functional block that converts an input character string into a character string containing kanji, kana, and kanji using a commonly available kana-kanji conversion method. This has two main functions: a word extraction function that extracts words from input reading character data, and a kanji conversion function that converts the parts of the extracted words that correspond to kanji into kanji. When a predetermined amount of input character strings are accumulated in the input temporary data buffer 28, the kana-kanji conversion algorithm 24 takes in data indicating the input reading character strings, indexes the conversion dictionary 2B such as a kanji dictionary and a grammar dictionary, and indexes the input character strings. Executes the Kana-Kanji conversion process. Since the specific processing in these functions is not directly related to the understanding of the present invention, a description thereof will be omitted.

Kana-Kanji conversion algorithm 24 and other blocks are:
It is advantageously realized by a processing system, such as a microprocessor, and is shown in blocks according to its functions in the figure. For example, the input device 20 is associated with a temporary input buffer 28 that temporarily stores input signals generated in response to operations of these keys.

The m actual processing unit 34 provides input data to the kana-kanji conversion algorithm 24 and converts the kana-kanji conversion algorithm 24
The Kana-Kanji conversion process, such as selection of candidate words output from Process.

In this embodiment, as shown in Figure $3, the reading is shown in brackets [], and the boundaries between words are shown in /.

The display circuit 30 is a circuit that controls the display device 22,
The display data is stored in the display memory 32. The display memory 32 accommodates two storage areas: a conversion area and an input line (reading) area. The contents of the editing processing section 34 are transferred to the convertible area under the control of the display circuit 30. This is achieved by the display circuit 30, which converts the display screen of the display section W22 shown in FIG. That is, it is displayed on the 22nd line. Further, the contents of the temporary input buffer 2B are transferred to the input row area under the control of the display circuit 30. This is performed by the display circuit 30 at the input display section 4 of the display screen.

By the way, the word cursor 4 in the converted character string display area 44
You may want to move 8 directly to the beginning or end of the sentence. In each case, the beginning of the sentence key 58 of the input device 20
Or, operate the end of sentence key 60.

For example, if you operate the sentence beginning key 5th, according to the flow in Figure 8, the cursor 40 is not at the beginning of the sentence (180
), the word cursor 44 is moved to the beginning of the sentence and one word at the beginning of the sentence is highlighted (186), and at the same time, the reading 46 is displayed (1B4), and the reading of the word at the beginning of the sentence is read and displayed in the character string display area 46. Display (18B). The character cursor 40 is positioned at the first character of the reading.

When the end of sentence key 60 is operated in the same way, the cursor 40 is not at the end of the sentence (20
0), moves the word cursor 44 to the end of the sentence.

As a result, the last character of the sentence is displayed in reverse video, and its pronunciation is displayed in the reading character string display area 46.

When there is an unconverted reading character string at the end of a sentence, the character cursor 40 is positioned after the last character of the reading.

Note that the embodiments described here are for explaining the present invention, and the present invention is not necessarily limited thereto, and modifications and variations that can be made by those skilled in the art without departing from the spirit of the present invention. Modifications are within the scope of this invention. For example, in the illustrated embodiment, the conversion line and the reading area are provided separately, but the reading area may not be provided separately, and the reading characters may be stored and displayed within the conversion line.
