Description

[Detailed Description of the Invention] The present invention provides a kanji-mixed sentence input device, particularly a kanji-mixed sentence that converts and confirms each word into a kanji word while inputting a hiragana sentence by key input to create a kanji-mixed sentence. The input device is configured so that the character to be converted into kana/kanji can be indicated by a cursor display, and the range of movement of the cursor is limited to the range where undefined displayed characters exist at that point in time, thereby preventing erroneous conversion. This invention relates to a device for inputting sentences containing kanji.

2. Description of the Related Art Conventionally, there has been known a kanji-mixed text input device that converts a hiragana text (including alphabetic characters and katakana) entered using a key into a kanji-mixed text.

However, in the case of conventional methods, (I) inputting hiragana sentences in advance and converting the desired words into kanji as part of the correction process, or (n) converting each hiragana sentence while inputting it, A known method is to create a work area for converting and finalizing words into Kanji words, separate from the Kanji-mixed sentence display area on the display screen.

However, similar to the latter method above, while inputting hiragana sentences, each word is converted into a kanji word and confirmed, and the work area is set on the kanji-mixed sentence display area for processing. A method to do so is being considered.

In this case, the operator has the advantage of being able to confirm the kanji-mixed sentences one after another while looking at the kanji-mixed-sentence display area. There is a risk of making a mistake and converting an already determined range.

The present invention aims to solve the above points,
Limits the cursor movement range to within the range of unconfirmed display characters,
The purpose is to be able to specify characters to be converted within the limited range.

Therefore, the kanji-mixed sentence input device of the present invention is a kanji-mixed sentence input device that creates a kanji-mixed sentence corresponding to the pronunciation of a word input by key input. an input character register in which data for at least one character inputted via an input device is set; a determination circuit unit that receives the contents of the input character register and determines the type of the content; and an instruction from the determination circuit unit. A character buffer that stores the contents of the input character register for at least one word correspondingly, a dictionary memory that stores kanji information corresponding to the pronunciation of the word, and accesses the dictionary memory in response to instructions from the determination circuit section. a dictionary search circuit section for controlling a display device, a display control section for controlling a display device, and a display device for receiving display data from the display control section and visually displaying the display data; A first display address register that stores the following first display address, a final display address register that stores the final display address of the undefined display character input as a conversion target, a cursor address register that stores the cursor display address, and the above A first comparison process that compares the contents of the first display address register with the contents of the cursor address register and updates the contents of the cursor address register in response to a cursor movement instruction based on the comparison result. and a third part that compares the contents of the last display address register with the contents of the cursor address register and updates the contents of the cursor address register in response to a cursor movement instruction based on the comparison result. It is equipped with two comparison processing units, and the cursor movement range is set to the above-mentioned top display address and
It is characterized in that it is limited to a range limited by the contents of the register and the contents of the final display address register.

This will be explained below with reference to the drawings. FIGS. 1A to 1E are explanatory diagrams for explaining processing aspects of the present invention, and FIG. 2 shows the configuration of an actual example of the present invention.

In FIG. 1, 1 represents a confirmed display character, 2 an unconfirmed display character, and 3 a cursor display.

The present invention has the following processing mode.

That is, (A) as shown in FIG. 1A, the range of movement of the cursor 3 is limited to the range where the unconfirmed display character 2 exists, so that the cursor display does not mistakenly cause the confirmed display character to become an undesired conversion target. Make it.

(B) As shown in FIG. 1B, unconfirmed display characters 2 are displayed in a different form from the display of confirmed display characters 1, so that the display of unconfirmed display characters 2 is made easier for the operator to see.

(C) As shown in FIG. 1C, the cursor 3 can be moved back in response to the unconfirmed display character 2 that has been input, and then the range sandwiched between the confirmed display character 1 and the cursor 3 Undefined display characters such as ``niyuuriyoku'' are converted into kana and kanji using the delimiter key.

Then, by pressing the cancel A key, it is possible to cancel the once converted display character, for example, "input".

(D) As shown in FIG. 1D, the display in the range between the confirmed display character 1 and the cursor 3, for example, ``niyuuriyoku'' can be canceled by pressing the cancel B key.

(E) As shown in FIG. 1E, immediately after performing kana/kanji conversion using the 1 and separator keys, the cancel C key is used to cancel the kana/kanji conversion itself using the separator keys.

FIG. 2 shows one example configuration of the present invention.

In the figure, 4 is a keyboard, 5 is an input character register, 6 is a judgment circuit, 7 is a character buffer, 8-0 is a character buffer pointer, and 8-1 is a character buffer copy pointer, which is the pointer mentioned above. those holding a copy of 8-0;
9 is a dictionary search circuit unit, 10 is a dictionary memory, 11 is a display control unit, 12 is a display device, and 13 is a start display address register, which is, for example, the start display address P of the undefined display character 2 shown in FIG. 1A. 14 is a final display address register that holds, for example, the final display address Q of undetermined display character 2 shown in FIG. 16 is a first comparison processing section, 17 is a second comparison processing section, 18 is a decrement circuit section, 19 is an increment circuit section, 20 is a flip-flop; 22 to 26 are AND circuits, 27 is an OR circuit, and 28 is an increment circuit.

Assuming that the display "Japanese" is now determined as shown in FIG. 1, the address P described above is held in address registers 13 and 14, respectively.

The process will proceed as follows. That is, (1) in this state, when the operator inputs the character "ni" using the keyboard 4, the determination circuit section 6 sets the illustrated signal "kana character" to logic "1".

(2) As a result, the character "ni" is set in the character buffer 7, and the content of the pointer 8-0 is set to the value "1".

(3) On the other hand, the AND circuit 25 is turned on, and the character buffer 7
The character “ni” inside is transferred to the display control unit 11.

At this time, based on the contents of the final display address register 14, the above character "ni" is displayed at the illustrated display address P in FIG. 1A.
will be displayed.

(4) When the display ends, the increment circuit section 28 sets the contents of the final display address register 14 to the value (P+1).

(5) Use the following key board 4 to make the letters “Yu” and “U”
, "ri", ... "chi", the display device 1
Unconfirmed display characters ``Niyuuriyoku'' are displayed on the screen of 2.

The contents of the final display address register 14 then become the value Q shown in FIG. 1A.

(6) At this time, the content of the cursor address register 15 has the same value as the content P of the first display address register, and when the operator instructs the cursor to move to the right using the cursor right movement key, the determination circuit unit 6 The illustrated signal "cursor right" is set to logic "1".

As a result, the second comparison processing section 17 compares the contents of the register 14, that is, the value Q, and the contents of the register 15, that is, the value P (generally χ).

(7) At this time, only when the relationship Q>χ exists, the increment circuit section 19 becomes valid, and the contents of the force-sol address register 15 are set to the value (χ+1).

(8) Thereafter, each time the operator operates the cursor right movement key, the contents of the cursor address register 15 are incremented by "1" as long as there is a relationship of Q>χ.

That is, the cursor 3 is shifted to the right one by one.

(9) After the relationship Q=χ is established, the contents of the cursor address register 15 are held at the value Q even if the operator operates the cursor right movement key.

That is, it is not changed. (10) When the operator instructs the cursor to move to the left using the cursor left movement key, the determination circuit section 6 sets the illustrated signal "cursor left" to logic "1".

As a result, the first comparison processing section 16 compares the content of the register 13, that is, P, and the content χ of the register 15.

(11) At this time, only if there is a relationship such that P〉χ,
The decrement circuit 18 is enabled and the contents of the cursor address register 15 are set to the value (.chi.-1).

(12) Thereafter, each time the operator operates the left cursor key, the contents of the force-sol address register 15 are incremented by 1 as long as P<χ.

(13) After the relationship becomes P-χ, the contents of the cursor address register 15 are held at the value P even if the operator operates the cursor left movement key.

That is, it is not changed. (14) As shown in Figure 1C, if the operator moves the cursor to the left three times, the
"Niyuuriyoku" is subject to kana/kanji conversion.

At this time, the pointer control unit 21 controls the address difference value (χ1P
) and set the contents of Boink 8-0 to (χ1P).

The original value (Q-P) is then saved in the copy pointer 8-1.

(15) In this state, when the operator operates the division key, the determination circuit unit 6 sets the indicated signal 1 division to logic "1".

As a result, the AND circuit 24 is turned on, and the characters "niyuuriyoku" from the character buffer 7 to the position indicated by the pointer 8-0 are read out and the dictionary memory 10 is searched.

At this time, the contents of pointer 8-0 are copied to pointer 8-0.
It is set from 1.

(16) The AND circuit 26 is also turned on, and when the kanji word "input" is read out from the dictionary memory 10, it is led to the display control unit 11 through the OR circuit 27, and then to the display device 1.
2.

The display address at this time is given by the contents of the final display address register 14.

(17) As shown in FIG. 1C or D, when the operator operates the cancel A key or the cancel B key at a certain point, the determination circuit unit 6 converts the indicated signal "cancel A" or signal "cancel B" into a logic "1".

(18) At this time, the display control unit 11 erases the undefined display character 2 based on the content P of the first display address register 13.

(19) Then, the AND circuit 23 is turned on, and the contents of the top display address register 13 are changed to the cursor address.
Set in register 15.

That is, the contents of the register 15 are forced to the value P.

Further, the contents of the pointer 8-0 are cleared to the value "0".

(20) Then, when the operator operates the character key again, the AND circuit 22 is turned on and the first display address
The content P of register disk 13 is the final display address register 1
Set to 4.

(2]) In the case shown in Fig. 2, the case of the cancel C key operation shown in Fig. 1E is not shown, but in this case, the character buffer is It may be considered that the contents are read out and displayed through the AND circuit 25.

As explained above, according to the present invention, the movable range of the cursor 3 is restricted when indicating the target of kana/kanji conversion by the cursor display, so that it is possible to prevent erroneous changes from being made to the confirmed displayed characters. do not have.

In addition, it is possible to select a part of the unconfirmed display characters that have been input to be converted, and it is also possible to return to the state immediately before inputting the unconfirmed display character or immediately after inputting the unconfirmed display character by pressing the cancel key.
