Abstract

PURPOSE:To simplify the operation even when no error exists by urging the operator to discriminate the propriety of the conversion and input a command before a converted character string is confirmed so as to progress smoothly an error correcting procedure. CONSTITUTION:When a converted character string ''It was rain yesterday, and it will be ...tomorrow'' is converted to the part and displayed on a conversion character display area 44, a Kana (Japanese syllabary) string ''fine'' is inputted from a read character key 12. A straight write converting section 24 converts the Kana string ''fine'' into a Kanji (Chinese character)/ Kana mixed character string ''fine'', transfers the result to a storage section 28 and a converted character string ''weather'' is introduced from the input character string ''weather''. Then the converting character storage section 28 detects that a character is stored in a storage area corresponding to a hot zone 48 of the converted character storage area and gives a command of generation of a warning tone to a warning generating section 32. The operator operates a confirmation key 14 when the converted character string displayed to a converted character string display area 44 is coincident with the string intended for the operator. When the converted character string displayed the converted character string display area 44 differs what the operator intends for, the operator does not operate the confirmation key 14 and corrects it by operating the function key 16 and the read character key 12.

Description

[Detailed description of the invention] Skin spots! The present invention relates to a character string processing device, and particularly to a character string processing device, such as a Japanese word processor or a translation machine, which derives and outputs another character string corresponding to an input character string.

For example, the Kana-Kanji conversion method, which is widely used in Japanese word processors, generates a converted string from an input string in units of words or segments.
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 conversion J", character strings are processed on a sentence-by-sentence basis.

It has the advantage of being simple to operate. However, on the other hand, since the opportunity to judge whether the conversion result matches the operator's intention is on a sentence-by-sentence basis, if a single sentence becomes extremely long, the unconverted string becomes long and A situation may arise where the data cannot be accommodated in the storage area of . therefore,
Due to system design, it is difficult to appropriately determine the maximum capacity of this storage area.

In order to avoid the risk of overflowing from the storage area, a confirm key is provided on the keyboard, and the operator operates the confirm key at an appropriate break in the sentence, thereby creating a semi-forced conversion opportunity. be. However, even with this method, the frequency of operation of the enter key is not low, and simplification of operation cannot be expected.

There is a method of determining the character string in response to the converted character string exceeding a predetermined length. In this method, determination may be forced even if there is an error in the conversion, and in that case, the correction process becomes complicated.

1-King The present invention overcomes these drawbacks of the prior art.

To provide a character string processing device that accurately converts an input character string into a character string intended by an operator with as simple an operation as possible.

1-Reduction The configuration of the present invention will be described below based on one embodiment.

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, in this embodiment, the keyboard lO
, an input determination section 20 , an input string storage section 22 , a solid writing conversion section 24 , a conversion dictionary 26 , and a converted string storage section 2
8, display section 30, alarm generation section 32, and correction processing section 3
4 and a character string processing section 3B.

As shown in the figure, the keyboard 10 includes a reading character key 12 for inputting reading (phonetic) characters such as kana characters, and a reading character key 12 for inputting reading (phonetic) characters such as kana characters, and a reading character key 12 for indicating that the input reading character has been converted into the intended kanji-kana mixed sentence corresponding to the input reading character. It consists of a confirmation key 14 for making corrections, and a function key 16 for giving instructions such as correction and cursor position. In addition, in this specification, the term "letter J" shall be interpreted in a broad sense to include not only kana and kanji, but also numbers, alphabets, punctuation marks, and other symbols.

The key input information sequentially input from the keyboard 1O is converted into a signal corresponding to the input information and sequentially transferred to the input determination section 20. The input determination unit 20 separates the input key information into kana character string information and processing information, transfers the character string information to the input character string storage unit 22, and transfers other processing information to the solid writing conversion unit 24, converted character The data is transferred to the string storage unit 28, character string processing unit 38, correction processing unit 34, and the like. The input character string storage section 22 has an accumulation area for temporarily storing these input kana character strings, that is, input character strings. This input character string is transferred from the input character string storage section 22 to the solid writing conversion section 24 and the display section 30, and the character string transferred to the latter is visually displayed on its display screen 38 (FIG. 4).

The solid writing conversion unit 24 is a processing unit that derives a corresponding appropriate, ie, provisional, Kanji/Kana mixed character string from the Kana character strings sequentially supplied from the input character string storage unit 22. The character string derivation is performed according to a predetermined algorithm while indexing the conversion dictionary 26. Any conversion algorithm may be used, but detailed description thereof will be avoided since it is not directly relevant to understanding the present invention.

The converted character string storage unit 28 has a storage area that temporarily stores the converted character strings derived by the conversion unit 24, and its contents are transferred to the character string processing unit 38 according to instructions from the correction processing unit 34 as described later. be done. It is also transferred to the display unit 30 and displayed. As shown in the figure, an alarm generating section 32 is connected to the converted character string storage section 28, and includes, for example, a piezoelectric sounding element, and as described later, an audible display for prompting the operator to confirm the converted character string. is generated in the form of an alarm sound.

The correction processing unit 34 is a processing unit that performs correction processing on the converted character string in response to the operation of the keyboard 0 when the converted character string stored in the converted character string storage unit 28 is desired to be corrected. The correction procedure and algorithm may be of any type, but since they are not directly related to the understanding of the present invention, detailed description thereof will also be avoided.

The finally determined converted character string is stored in the converted character string storage section 28.
The data is transferred from there to the character string processing unit 36 and stored therein.

The character string processing section 36 is a section that implements the original functions of a word processor, such as document editing processing. The character string data processed here is edited into a document and output from the output port 40, for example, printed out on a printing device, stored in a storage device, or sent to others via a communication line. Sometimes it happens.

The display section 30 is a character display device constructed of, for example, a CRT, and on which a plurality of characters are visibly displayed as shown in FIG. 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 there are 24
It consists of lines. The hatched portion 42 has a converted character string display area 44 on the 22nd line and an input character string display area 4B on the 24th line, as shown in FIGS. 38 to 3D. A hatched portion 48 at the right end of the converted character string display area 44 is a so-called hot zone and has a display capacity of multiple digits.

Its functions will be described later. Note that the characters "Jikana/Kanji" on the left end of the 24th line are a display example indicating that the automatic kana/kanji conversion mode is being operated.

Returning to FIG. 1, the operation will be described with reference to the operational processing flow of the apparatus shown in FIG. 2. When input information is sequentially input from the keyboard IO, the input determination unit 20 separates the processing information and the input character string of reading characters, and sequentially transfers the latter to the input character string storage unit 22 for storage (step 10
2). The input character strings transferred to the input character string storage section 22 are on the one hand transferred to the display section 30 and sequentially displayed on the input string display area 46 of the screen 38, and on the other hand are also sequentially displayed on the solid writing conversion section 24. be transferred.

The solid writing conversion unit 24 converts the input character string into a suitable converted character string by referring to the conversion dictionary 26.
That is, sentences containing kanji and kana are sequentially generated and transferred to the converted character string storage section 28. This is transferred to the display unit 30 and sequentially displayed in the converted character string display area 44 on the screen 38. Such processing is performed in step 1 of Fig. 2.
00.102. and 104.

Therefore, as will be described later, when the enter key 14 is operated in this state (log), the corresponding input string at that point is cleared, and the converted string at that time is transferred to the string processing section 3B (toe). This completes the series of processes for the time being, and thereafter, by repeating these operations for successively input character strings, the input character strings are processed in sequence.

For example, as shown in FIG. 3A, when the conversion progresses to the converted character string "31. It rained yesterday. Tomorrow" and is displayed in the converted character string display area 44, the kana character string It is assumed that "Tenki ni" is inputted using the reading character key 12. In this example, the final character "wa" of the converted character string has not yet reached the hot zone 48. Therefore, the solid writing conversion section 24 first converts the kana character string "Good" into a Kanji/Kana mixed character string "Good" and transfers it to the storage section 28. This is displayed in the display area 44, but as shown in FIG.
rush into. Following this, the converted character string "weather" is derived from the input character string "tenki".

Therefore, the converted character storage unit 28 detects that characters have been accumulated in the storage area corresponding to the hot zone 48 of the converted character storage area (14), and instructs the alarm generation unit 32 to generate an alarm sound (108). ). This is done by the operator using the confirm key 1.
This means that the state in which 4 should be operated has been reached, and the operator is prompted to do so.

Then, when the converted character string displayed in the converted character string display area 44 matches what the operator intended, the operator operates the enter key 14 (110° 112). As a result, the previously converted character string "91. It rained yesterday. Tomorrow will be fine" is transferred to the character processing unit 36 and cleared (108). Therefore, only "weather" is displayed as the converted character string, as shown in area 44 of FIG. 3D.

Instead of operating the confirm key 14, the reading character "naru" may be further input using the character keys (FIG. 3C). In response to this, the solid writing converting section 24 performs the same processing as when pressing the confirm key, and the previously converted character string "20. It rained yesterday. Tomorrow will be fine" is transferred to the character processing section 3B.
cleared. Therefore, the converted character strings are displayed as "weather" in the converted character string display area 44 and "become" in the input character string table 77q area 46 (10
B).

If the converted character string displayed in the converted character string display area 44 is different from what the operator intended, the operator does not operate the confirmation key 14 and presses the function key 1B or reading character key 1.
Correct by operating 2 (110). As a result, the correction processing unit 34 performs correction processing on the converted character string (1
1B).

The confirmed character string transferred to the character string processing unit 36 in this way is
After being edited as a document, it is finally sent to output port 4.
0 to be output for storage, recording or transmission.

The embodiments described here are for illustrating the present invention, and the present invention is not necessarily limited thereto. Modifications are within the scope of this invention. For example, in the illustrated embodiment, an audible sound is generated as a means to prompt the operator to confirm. However, instead of this,
Alternatively, in addition to this, a visible display may be used, such as lighting or blinking a light emitting element, or outputting a clear visible display on the display screen 38.

肱-1 According to the present invention, before finalizing the converted character string, the operator is prompted to judge the validity of the conversion and input instructions thereof.

This allows the error correction procedure to proceed smoothly and also simplifies the operation when there are no errors. Therefore, the total frequency of keystrokes by the operator is low, and input character strings can be easily and accurately converted into character strings intended by the operator.
