Abstract

PURPOSE:To utilize a display effectively, facilitate key operation, and improve operativity by flashing segments of a format display for one pages corresponding to the cursor position on the one-line display. CONSTITUTION:A KANA (Japanese syllabary) character string inputted on a keyboard 1 is inputted to an input sentence buffer 3 through a CPU2 and displayed on the one-line display part 4. When a conversion key is hit and homonyms are selected, the CPU2 transfers the candidate displayed last from a conversion candidate buffer 8 to an output sentence buffer 5. The CPU2 further displays the format of one page on the format display 9 while each character in the output sentence buffer 5 corresponds to one dot. The dot on the format display corresponding to the cursor position on the one-line display 4 is flashed to obtain the correspondence between the one-line display 4 and format display 9.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a Japanese input device using a kana-kanji conversion method, which inputs Japanese sentences while converting a character string input in kana to a sentence containing kanji and kana. .

<Prior art> In the case of the Kana-Kanji conversion method, unlike direct input methods such as the Furuki method, both the pre-conversion kana character string and the post-conversion Kanji-kana exchange text are displayed on the same display. Especially when a one-line display is used, the operability may be poor.

CRT is used as the display device of the Japanese input device using the Kana-Kanji conversion method.
Devices using a screen display such as the above have been in existence for some time, but using a screen display increases the size of the entire device and increases the cost. Using a one-line display allows for a smaller device and lowers costs, but compared to a screen display, only one line of the entire screen can be displayed at a time, making it difficult to input, edit, and modify. Inferior.

<Purpose> The present invention aims to improve operability by effectively utilizing the display and simplifying key operations even though the display device uses, for example, a one-line display. The present invention provides a small, low-cost, and easy-to-use Japanese input device using a kana-kanji conversion method.

<Embodiment> Fig. 1 shows a block diagram of an embodiment of the present invention, and Fig. 2 shows a block diagram of an embodiment of the present invention.
The figure shows an external view, and FIG. 3 shows a detailed plan view of the keyboard section.

The keyboard 1 consists of, for example, flat keys in the form of a flat tablet, and as shown in FIG.
A group of phonetic kana keys 1a is arranged.

The key group 1b below the 50-syllabary kana key group 1a is number/alphabet keys arranged so that numerical values and alphabetic characters can also be entered.

Adjacent to the left is a key group 1c that is mainly operated during kanji conversion, including conversion keys for instructing kanji conversion, and adjacent to the right are the voiced mark (4) key and the handakuten (0) key. ) key, punctuation mark (,) and (.) key, etc., mainly the kana key group 1a.
A key group 1d is arranged to be used in conjunction with. Further, a group of keys 1e and 1f, which are mainly used to perform overall control, are arranged at a distance from each other to the left and right.

The keyboard 1 as described above is positioned on the device as shown in FIG. 2, and any input can be made by placing the hand on the device and moving the press bar S using the wrist as a fulcrum without changing the position. It is of a size that allows it to be used.

In FIG. 1, a kana character string input from a keyboard 1 is passed through a CPU (central processing unit) 2 to
It is once introduced into the input sentence buffer 3 and displayed on the one-line display 4. At this time, the input kana character string is displayed together with the already converted kanji-kana mixed sentence - stored in the output sentence buffer 5. In this embodiment, a display with 30 characters per line is used, and up to 28 characters can be entered per line.

If you press the conversion key here, the CPU 2 will process the processing progera l,
According to the program in section 6, the dictionary 71 and memory 7 are searched based on the contents of the input sentence buffer 3. The dictionary memory 7 stores kanji notations corresponding to kana headings that can be searched by phrase. If a corresponding date is found as a result of the search, CPU2
transfers the kanji notation part of the conversion dictionary to the conversion candidate buffer 8, and simultaneously displays one of the candidates on the one-line display 4 in place of the input kana character string. As will be explained in detail later, the kanji to be converted can be arbitrarily selected.
The selected characters are displayed on the one-line display 4 while being switched one after another. If a specific kanji is selected, the keyboard F I
The next kana character string can be input by operating , and the kanji specified above or a kanji-kana mixed sentence containing this kanji is input to the output sentence buffer 5 and stored.

The format display 9 is provided on the left side of the keyboard 1 as shown in FIG. 2, and displays the format (outline) of the entire input sentence.

A more detailed explanation will be given below with reference to detailed block diagrams of main parts, flowcharts, etc.

A kana character string inputted from the keyboard 1 is temporarily entered into an input sentence buffer 3 via the CPU 2 and displayed on a one-line display 4. The kana character string input at this time is stored in the output sentence buffer 5 and is displayed differently from other characters (black and white inverted, squared, different typeface).

An example of this display is shown in FIG. 4(a). As an example, in the last line (the line including the cursor position), a case is shown in which ``Japanese 1 is already converted into a kanji-kana-mixed sentence, and ``kansei-'' is input. In the figure, the - mark indicates the starting position of the line, and the U mark indicates the cursor position. As described above, this embodiment uses a display with 30 characters per line, and up to 28 characters can be entered per line. Although the number of characters per line can be set arbitrarily by a separate instruction from the keyboard 1, hereafter, for the sake of simplicity, it is assumed that the number of characters per line is set to 28 characters.

FIG. 5 is a block diagram showing the main parts in detail.

Sentences containing kanji and kana that have already been converted are sent to output sentence buffer 5.
is stored in On the one-line display 4, the line including the cursor position is displayed from among the stored sentences containing kanji and kana. "Japanese" in FIG. 4(a) corresponds to this. Here, when the kana character string "Kansei" is input using the keyboard 1, it is stored in the input sentence buffer 3. Each character data is displayed by writing the character pattern extracted from the CG (character generator) 11 into the refresh RAM 12, but when character data is supplied from the input sentence buffer j, the CPU 2 inverts the character pattern extracted from the CGII. Refresh RAM as 1.2
write to. As a result, as shown in FIG. 4(a), "gansei" is inverted in black and white, and is displayed to distinguish it from the kanji, kana, and character symbols that have already been converted.

In the case of using square boxes, different fonts, etc., the character data from the input sentence buffer 3 is supplied in the same way.
CG], ] may be controlled.

When the conversion key is pressed, the dictionary memory 7 is searched, and if the corresponding data is found, the CPU 2 moves the kanji notation part of the conversion dictionary to the conversion candidate buffer 8. Then, the CPU 2 extracts the first candidate from the conversion candidate buffer 8 and displays it in place of the input kana character string displayed earlier on the one-line display 4.

An example of the display at this time is shown in FIG. 4(b). As is clear from FIG. 4(b), the number of homophones (the number of candidates taken out to the conversion candidate buffer 8) is added and displayed immediately after the converted character. The kanji notation of the conversion result is in normal letters, and the number of homophones is highlighted or boxed to distinguish it from the numbers included in other normal sentences, or to indicate that the following homophones can be selected. etc. will be done.

The number of homophones is stored in conversion candidate buffers 80P and QK.

P is the total number of homophones, and Q is the remaining number of homophones. When the conversion key is pressed, a corresponding character pattern is extracted from the CG 1.1 according to the first candidate data in the conversion candidate buffer 8 and stored in the refresh RAM 12. The character pattern extracted at this time is not inverted similarly to the output sentence buffer 5 and is displayed normally. However, when displaying the number of homophones (remaining number of homophones Q), CPU2
The character pattern taken out from II is written as an inversion into the refresh RAM 12 and displayed in reverse.

In the display example shown in FIG. 4(l), "F completed" is entered as the first candidate, and this is selected and displayed.

When the next candidate key is pressed from the keyboard], the CPU 2 takes out the next candidate from the conversion candidate buffer 8 according to the program of the processing program device 6 and replaces it with the first candidate "Complete" already displayed on the one-line display 4. . At this time, the number of homophones is 1 to display the remaining number of homophones.
Minus. For example, "Completion" is displayed as "Quiet" and the number of homophones is 9. If you press the next candidate key further, the next candidates will be displayed one after another. If you press the next candidate key again when the number of homophones is displayed as 1, it will return to the beginning again as shown in Figure 4 (
b) The previous candidate key is a key that selects candidates in the opposite direction to the next candidate key, and is particularly effective when there are many homophones and the next candidate key is pressed too many times, or when selecting a homophone with a low candidate ranking. be.

The operation flow associated with the suppression operation of the next candidate key and the previous candidate key is shown in Figure 6, and the total number of homophones P is provided for transfer and comparison for the cycle operation of each key, and one line On the display 4, the number Q of remaining homophones is displayed.

When the homophone selection is finished and the next kana character is input, C
The PU 2 moves the last displayed candidate from the conversion candidate buffer 8 to the output sentence buffer 5, newly inputs the input kana character string to the input sentence buffer 3, and at the same time replaces it with the inverted display of the number of homophones on the one-line display 4. Display.

If the CPU 2 searches the dictionary memory 7 based on the conversion key instruction and finds no corresponding data, the contents of the input sentence buffer 3 are transferred as is to the conversion candidate buffer 8, and the kana character string to be converted is displayed normally, with the same sound The number of words will be O.

Next, a case where the number of displayed characters exceeds the number of characters on the one-line display 4 will be explained. As an example, it is already displayed that "Japanese input devices that use the F-kana-kanji conversion method are very convenient," and [The relationship between key manual input and display when inputting J and "to" mechanically is shown below. . In addition, the reversed display is shown in Gothic font and with a blank space marked with an ○ mark.

is the initial state, display 2 is the state where one line of display 4 is full, display 3 is the state where one more character is input and the whole is shifted one character to the left, display 4 is the state where kana characters are input for the converted logarithm. Display 5 shows the state where the conversion key has been pressed (at this time, note that the first character of the conversion result is at the beginning position of the kana character to be converted), Display 6 shows the state selected by the next candidate key, Display 7 is displayed in a state in which the next kana character has been input, in which case one of the homophones is considered to have been determined and is not shifted (moved to the next line). Display 8 is a state in which the conversion target "to" is not converted by pressing the no conversion key (the display of "to" is replaced with a normal character), and display 9 is a state in which the cursor is moved up and the previous line is displayed. The situation is as follows.

In FIG. 5, A of the output sentence buffer 5 stores the number of characters that can be displayed on the one-line display 4 (which can be set using the keyboard 1), and B stores the character position from the beginning of the line. Further, C of the input sentence buffer 3 stores the number of input kana characters. In the case of the display example in FIG. 4, A=28. B=5. C
=4.

As shown in the flowchart of FIG. 7, when the flag F=O of the CPU 2, kana data is taken into the input sentence buffer 3 every time there is a kana power. And A and (
B+C) are compared. If A is larger, the characters are not shifted and the input kana characters are displayed one after the other. When (B+C) is larger,
-1 character position B and move the entire 1-line display 4 to the left by 1
Shift and display by characters. In other words, even if the number of characters on the one-line display 4 is exceeded during the input of a kana character string, all the input kana character strings can be displayed on the right edge of the one-line display 4. can. If you press the conversion key and then the next candidate key or previous candidate key, the results will be displayed based on B, so the first character of the conversion result will be at the first position of the kana character to be converted, and all conversion results will be displayed. It will be done.

If you press the conversion key, the flag F = 2, so when inputting a new kana character string, input buffer 3 is cleared and input data is taken in, the conversion result is transferred to output sentence buffer 5, and along with this, The contents of character position tiffB are rewritten and returned to normal display.

As described above, in this example, the conversion target and the conversion result can all be displayed at once using the ox determined by the homophone. If you move to the next line without shifting to the left when you exceed the number of characters in one line, only the second half will be displayed, resulting in very poor operability. Furthermore, in this example, when a homophone is determined, the display automatically returns to the unshifted W-shaped display, allowing the operator to continue inputting using natural operations. A homophone is considered determined when a key other than conversion, no conversion, cancellation, onkun, previous candidate, and next candidate is pressed.

As mentioned above, in order to reduce the burden on the operator when inputting data, we try to avoid prohibiting manual input of settings and keys as much as possible, and when the device is in input mode, conversion,
The functions of function keys such as no conversion, cancel cursor left/right shift, and delete key are always enabled. The operation and display method of example sentence human power will be explained below with reference to the flowchart of FIG.

Example 1. “Thank you very much.” Combination of transform, undo and left/right shift Wrong conversion unit Display I will help you with your key human resources. Display Please give me a request.

key person crab conversion Display〜Please help me L Key human power cancellation Display Please give me a request.

Key person crab・−←・−m=・−1 Display Please, I will do it again Key person crab conversion display 1 Please 1 I will do it again Key person crab→ Display J Example 1 is a case where two phrases are input by mistake, and when the first conversion key is operated, there is no corresponding data in the dictionary entry 7, and the data is displayed without conversion. When the cancel key is operated, the operation of the conversion key is canceled and the display returns to that of the previous input sentence buffer 3 and is displayed in reverse video. Here, the flag becomes F=0, and when the left cursor movement (.-) key is pressed, the cursor moves by the number of days pressed. This moves the cursor to the position corresponding to one clause. When you press the conversion key, the highlighted character in front of the cursor is converted, the corresponding part becomes normal display, and the number of homophones is displayed. Note that at this time, since the kana character string after the cursor is the 11 characters left in the input sentence buffer 3, this is also displayed in a reversed state. When the conversion key is pressed, flag F=2 is set. Therefore, when the right man-sor movement (-) key is pressed next, the previously converted portion of the input sentence buffer 3 is cleared and the cursor is skipped to the end at once and returned to the normal position. After that, press the normal conversion key to convert the remaining input kana string.

Example 21 "Japanese" Correct display for input errors using combinations of conversion, undo, left/right shift, and delete keys.

The kana character input ``ha'' is taken into the corresponding position of the input buffer 3. Since the cursor movement to the right is flag F20, it is moved by one for each suppression in the usual way.

Example 3. “I can tell you.” Combination of conversion and no conversion Display can be conveyed.

You can crab with the key in. Display - can tell key person crab conversion Display - ability to convey 1 Kill crab no conversion Display 1 Can be conveyed Key human power conversion Able to display and convey information1 Key human power ° no conversion Display - Can be conveyed.

Key person crab cancellation display 1 You can convey the verbal conversion key, just like when you press the conversion key and the corresponding data is large, the contents of the input sentence buffer 3 are directly sent to the size conversion candidate buffer 8 and displayed. be done.

Switching between the conversion key and the non-conversion key is simply selecting data from the conversion candidate buffer 8, and the non-conversion key or the conversion key can be directly pressed as desired. Also, the ability to press the cancel key without conversion is the same as in the case of the conversion key.

Example 4. "You can input Japanese quickly" Displays a combination of insertion and conversion - 1 key person crab that can input Japanese (- (- - 1 (- Display - Displays the key human power that can input Japanese quickly) , Keys that can be entered manually Conversion display 1 Keys that allow you to enter Japanese quickly, display of next candidates 1 Kana characters that can be entered quickly by yourself Kana character input is always possible, move the cursor and press the Kana key At this point, the character data converted first is transferred to the output sentence buffer 5. On the other hand, the kana character string is imported into the cleared input buffer 3 and displayed in reverse.The insertion and position are controlled by the cursor position. Kanji can be converted in the same way even in sentences.

Example 5. "Easy to input Japanese" Combination display of insertion and deletion conversion Key power that allows you to input Japanese quickly; 0 key display Key power that allows you to input Japanese quickly Key-powered, easy display - Key-powered, easy-to-understand Japanese language conversion display that allows you to easily enter Japanese with Δ input <IEIIK> Characters in both the left and right directions can be erased with the key,
As shown in Example 4, it shows that sentences can be inserted.

Next, punctuation mark conversion will be explained. FIG. 8 shows a flowchart of punctuation mark conversion. When the period (.) key is pressed, the period (.) is input into the input sentence buffer 3 and is automatically converted even if the conversion key is pressed. Of course, in this state, a specific item can be selected by pressing the next candidate key or the previous candidate key.

By using punctuation mark conversion in this way, usually ■ Kana Jinriki, ■ Conversion, 0th candidate (or previous candidate), 0 punctuation mark (.

), so in contrast, ■kana human power, 0
The number of input operations can be reduced by one step for a period (.) and a zero-order candidate (or previous candidate). If you want to input kana as is, you can use the normal operation of ■Kana human power, ■No conversion, and zero period (.). The same goes for commas (,).

As explained above, the operability of kana-kanji conversion input is greatly improved even though it is a one-line display, but since the format of the entire input sentence cannot be grasped on a one-line display, the CPU 2 also uses an output sentence buffer. 5 corresponds to one dot] Using the format display 9 that shows the format of the negative sign (dots are lit where there are characters, and dots are lit where there are no characters such as spaces and tabs). By blinking the dot on the format display corresponding to the cursor position on the single-line display 4, the single-line display 4 and the format display 9 are made to correspond, and although it is small, it has the same operability as a CRT screen display. It is made to have.

FIG. 9 is a plan view showing a display example of the format display 9. As shown in FIG.

In the above embodiments, the display device has been explained as a one-line display, but this is because the present invention is particularly useful for a one-line display. It can also be applied to a kanji conversion input device. ! f. The present invention can be applied to any arbitrary method such as kana-to-kanji conversion by word-by-word conversion, kanji-by-kanji conversion, or phrase-by-phrase conversion.
