Abstract

PURPOSE:To decrease scrolls by using the area of a displayed drawing for display of converted KANJI (Chinese characters) for a prescribed period in a KANA (Japanese syllabary)/KANJI conversion mode and using an entire area in a normal mode in a process excepting for the KANA/KANJI conversion. CONSTITUTION:The KANA corresponding to the desired KANJI is supplied to a key group K and then stored in an original buffer 9. Then the input KANA is stored in a display buffer 7 and displayed after the guidance data on the lower lines of an LCD 3. A CPU 1 gives an access to a dictionary table data area in a ROM 5 with push of a conversion key and reads out the KANJI data coincident with the contents of the buffer 9. Then the CPU 1 stores said KANJI data in a KANA/KANJI conversion buffer 10 and displays it on the lower lines of the LCD 3 after setting a conversion flag in a RAM 6. When an adoption key is pushed at a time point when the desired KANJI is displayed, this KANJI is fetched into a basic program. Then the conversion flag is reset and a normal mode is displayed again.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a display control method for a Japanese language processor.

(Prior art and x points) Hitherto, portable computers, pocket computers, portable word processors, and the like have been known as fco Japanese processing systems equipped with a kana-kanji conversion function. The display capacity of the display screen of the display unit in one cycle of this type of small language processing is usually small, about a few middle digits x a few lines.

By the way, there are many homonyms in Japanese, so when converting to kana-kanji, it is necessary to check on the screen whether the displayed kanji corresponds to the desired word, but as mentioned above, with portable computers etc. Since the display capacity is small, scrolling (advancing) four screens frequently occurs depending on the manually written kana characters and converted kanji characters, making it difficult to see and confirm the characters on the display screen. There is also the problem that as the number of scrolls increases, power consumption increases accordingly.

As a countermeasure to the above problem, it is possible to use a part of the display screen, for example, one predetermined line, exclusively for kana-kanji conversion, but in this case, processing other than kana-kanji conversion, such as creating a program in a basic language, etc. This method is unsatisfactory because it has the disadvantage that the display capacity is limited.

(Means for Solving the Problems) The present invention aims to solve one of the above-mentioned problems, and this purpose is to provide a Japanese language processing machine with a relatively small capacity display screen, during kana-kanji conversion processing. During a predetermined period, part or all of the area of the above display screen is used to display input kana characters and converted kanji through so-called interrupt processing, while the entire area of the display screen is interrupted during processing other than kana-kanji conversion. This is achieved by using the normal display mode without

The capacity of the area used to display the input kana characters and converted kanji through the above interrupt processing is set to a capacity corresponding to the average number of characters in one Japanese phrase, or a capacity slightly larger than that. is preferable, as this can greatly reduce scrolling when inputting kana or kanji. Specifically, the display screen is configured with an appropriate number of digits x several lines, and during a predetermined period during which kana-kanji conversion processing is performed, some or all of the lines are used as display areas for input kana characters and converted 1 kanji. It can be used as a.

For example, the display section may be configured with a 188-digit x 2 display screen, and the bottom row may be used as a display area for manually input kana and converted kanji.

(Example) The present invention will now be described in detail with reference to the accompanying drawings.

Figure 1 shows a basic (BASI) system that employs the method of the present invention.
C) A block configuration of a portable computer capable of programming in a language (hereinafter referred to as a basic program) is shown.

This portable computer has a central processing unit (CPU)
The CPU I is connected to the display screen of the liquid crystal display unit LCD3 via the liquid crystal display unit controller 2, and is also connected to a group of keys (■) described later.

It is connected to a storage device consisting of 6. The above ROM5 contains the system program, kana-kanji conversion program, LC
Character font pattern used for display on D3,
Dictionary table data and the like are stored in each corresponding area.

As shown in FIG. 2, the RAM 6 has a display buffer 7.
, a text buffer 8, an original text buffer 9, a kana-kanji conversion buffer 10, a work area 11, etc.

The display buffer 7 is a buffer that stores characters, symbols, etc. to be displayed on the LCD 3. In the thick screen example, the LCD 3 has a display capacity of 9 digits x 2 lines. Accordingly, the display buffer 7 has a storage capacity for 18 characters. DP is the write address of the display buffer,
That is, it is a register that stores the address to be written next.

-1- The text buffer 8 is used to store a knock program created by the user. Store the input address in register TP. Also, store the start address of the text buffer data currently displayed on the LCD 3 in the register.

The original text buffer 9 is a buffer for storing 257 kana characters input during a kanji input operation, and the kana-kanji conversion buffer 10 is a buffer for storing kanji characters corresponding to the input kana characters. The old addresses to these buffers 9 and IO are stored in registers GP and KP, respectively. 12 is a register that stores guidance data for each conversion mode, which will be described later, and MP is a mode flag that stores the conversion mode selected at that time.

Next, while referring to the external view of this portable Nimbu-ri shown in FIG. 3, explain the details of the key group I.

In Figure 3, 1 is a group of manual keys, k2 is a numeric keypad, and k

5 is a conversion mode switching key, and
), switching is performed between each mode of kanji conversion, specifically, the bunsetsu conversion mode, proper noun conversion mode, onkun conversion mode, and kuten conversion mode. As shown in the figure, when the kanji manual display mode is executed, the mode selected at that time is used as guidance data, and is displayed at the beginning of the lower row of CD 3. As shown in Figure 6 (a), (b) and Figure 7 (a), (b), the phrase conversion mode is a mode for converting human-written Japanese sentences in kana into kanji phrase by phrase, and proper nouns. The conversion mode is a mode for converting proper nouns. In addition, as shown in FIGS. 8(a) and 8(b), the onkun conversion mode is a mode in which a desired character is selected by enumerating kanji (one character) having a specific sound;
As illustrated in a) and (b), the Kuten conversion mode is a mode that calls a desired character using a predetermined Kuten code.
Ru.

K6 is a conversion key, which is used to perform conversion in each of the above modes (phrase conversion mode in the illustrated example), as illustrated in FIGS. 10(a) to 10(d). If the first displayed character is not the desired character, pressing this conversion key again will display other conversion candidates in sequence. Also, if you press 7 on the shift key and 6 on the conversion key, the previous conversion candidate (previous candidate) will be displayed again (Figure 1O (d)).

kg is the adopted key, and Fig. 11 (a), (b) and 12
As shown in Figures (a) and (1)), when this key is pressed when the desired converted character or kana is displayed, the converted character or kana is imported into the Bentzk program and displayed on the LCD 3. The mode returns to normal display mode. Further, if the shift key 7 and the adoption key kill are pressed during kana-kanji conversion as shown in FIGS. 13(a) and 13(b), the conversion is canceled and the character ``Otsu'' is displayed.

kg is a delete key, which is used to delete the character one character to the left of the cursor and move the cursor one character to the left, as illustrated in FIGS. 14(a) and 14(b).

klQ is a clear key, which is used to erase the entire kanji input line as illustrated in FIGS. 15(a) to 15(c).

kll, k12 are cursor up and down movement keys, k13, k1
4 is a cursor left/right movement key.

Two operating examples of this portable computer will be described below.

FIGS. 16(a) and 16(b) show the display contents of the LCD 3 while the basic program is being created. In this state, LCD3
is used in the normal display mode.

If you want to enter a new kanji manually, press 3 on the kanji key, the CPU will set the register DP to the 10th character, and if it is displayed in the lower row of LCD 3, Clears the displayed contents of a row. Then, the conversion mode selected at that time is determined based on the mode flag MP, and the guidance data (in the illustrated example, [Phrase]) of the mode is read out from the register 12 and stored in the display buffer 7. Figure (a), (
b) Display at the beginning of the lower line of the LCD 3, and also erase the contents of the original text buffer 8. In addition, the above key kl-k
FIG. 24 shows an operation flowchart for operation No. 14.

Next, manually select the kana that corresponds to the kanji you want to manually type.
These are stored in the original text buffer 8, and the contents of the original text buffer 8 are subsequently stored in the display buffer 7, as shown in FIG.
A), (b) are displayed on the lower row of the LCD 3 following the above guidance data.

These kana are preferably displayed in reverse video. Hatching in the figure indicates reverse display.

Then, when 6 is pressed on the conversion key, the CPU 1 becomes R
Access the dictionary table data area in OM 5,
One or more rumored character data (conversion candidates) that match the contents of the original text buffer 8 are read out, stored in the kana-kanji conversion buffer 9, and a conversion flag (not shown) in RAM G is set. First, the first conversion candidate is stored in the display buffer 7, and as shown in FIGS. 19(a) and (b),
It is displayed in the lower row of D3 following the guidance data.

At this time, the number of conversion candidates is displayed in reverse video at the end of the lower row of the LCD 3. If the displayed kanji is not the desired character, press 6 on the above conversion key again to display other conversion candidates.

If the above conversion flag is set, the conversion key is 6.
By holding down , each conversion suggestion will be displayed in sequence.

As shown in Figure 20 (a) and (b), if the phrase to be input is long and contains 7 or more characters in Kanade (in the example shown, "About Shinden Shikei Sanki"), the lower part of the LCD 3 In the line, the guidance data is displayed as it is, while the input data is sequentially scrolled to the pressure. When the user presses the conversion key 6 after completing the kana input, the guidance data is first displayed, followed by the first six characters, and then an arrow indicating that there are subsequent characters is displayed, as shown in FIG. 20(c).

If the user continues to press the cursor right movement key k14, the following characters will be displayed (FIG. 20(d)). If you want to see the first group of characters again, just press the cursor left movement key k13 (FIG. 20(e)).

When a desired kanji is displayed, pressing 7 on the adoption key causes the kanji to be stored in the text buffer 7 and incorporated into the basic program.

Further, the conversion flag is reset, the display mode is returned to the normal mode, and the program including the input characters is displayed as shown in FIGS. 21(a) and 21(b). At this time, Figure 21 (a
) and (b), the line scrolling is not performed or the upward line scrolling is performed as necessary based on the flowchart described later.

Note that if you input the next kana without pressing 7 on the recruitment key in the state shown in Figure 19 (a) or (b), the result will be as shown in Figure 22 (a),
As shown in (b), the kana is displayed on the lower line in the display mode for inputting kanji characters, and the converted characters are imported into the basic program. Also, Figure 21 (a), (b)
In this state, simply inputting kana without pressing 3 on the kanji key will automatically switch to kanji input mode and display the screen shown in Figure 22 (a).
), (b) may be displayed.

Next, the procedure of kanji input processing (including kana input) will be explained based on the flowchart of FIG.

In Figure 23, when inputting kanji, first step S
Check register TP of text buffer 8 with I, and select S2
Determine whether the conversion flag is set. If set, it is a kanji input, so the contents of the kana-kanji conversion buffer 10 are transferred to the text buffer 8, a predetermined kanji is imported into the basic program, and the conversion flag is reset (S3 and S4). If the conversion flag is not set in S2, it is a kana input, so the contents of the original text buffer 9 are transferred to the text buffer 8, and the predetermined kana is imported into the basic program (S
5).

Next, subtract the value of register HP (the starting address where display buffer 7 is being displayed) from the value of register TP (address written to text buffer 8), and subtract the result from 18 (display address of L CD 3). (S6). If it is larger than 18, the newly input part in the basic program will overflow from LCD3, so 9 is added to the value of register IIP in S7.
After scrolling the display contents of the LCD 3 upward by one line, the process returns to S6 and repeats the same operation. Next, in step 88, the contents of the text buffer 8 for 18 characters are transferred from the HP to the display buffer 7, and the basic program is displayed.

In the actual example below, the LCD 3 has a display capacity of 9 digits x 2 lines, but if the display capacity is small, the entire area can be used to display the input kana and converted kanji. You can also do it. Also, a display device other than an LCD may be used as the display screen. Further, in the above embodiment, a portable computer has been described, but it goes without saying that the present invention can also be applied to other Japanese language processing machines.

(Effects of the Invention) As explained above, according to the present invention, when performing a kana-iritsuno, a part or the entire area of the display screen is dedicated to displaying manually input kana characters and converted kanji by interrupt processing. Since it is set to zero, scrolling on the display screen when inputting kana can be effectively reduced, making it easier for the user to see inputted kana or converted kanji, making it easier to input kanji or kana. Useless scrolling when inputting Matakana is reduced, and power consumption is also reduced.

Furthermore, when performing processing other than human power, the entire display can be changed to normal display mode without interrupt processing!・Since it is used as a display, it is necessary to ensure sufficient display capacity when performing the processing.
