Abstract

PROBLEM TO BE SOLVED: To improve the operability and the burden on a user when a character is selected by code input. SOLUTION: When a character corresponding to code information is selected on a character list selection screen, the numerals of the respective digits constituting the code information are inputted in order from the high-order digits (A11-A13). Each time a numeral is inputted, it is decided whether or not the current input code is an effective code and when it is decided that the information is the effective code (Yes in A14), a cursor is moved on the character list selection screen to the character corresponding input code information to select the character (A15).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device such as a Japanese word processor, and more particularly to a character selection method used in a document creation device having a code input function.

[0002]

2. Description of the Related Art Conventionally, a document creating apparatus such as a Japanese word processor has a code input function and can input a symbol that is not on a keyboard or a Chinese character that is not converted by using a JIS code or a kuten code.

By the way, when a desired character is obtained by inputting a code, a character list selection screen is usually displayed, and a code (4 digits or 5) corresponding to the desired character is displayed on the screen.
After entering all the digits, press the "Enter" key or "Ent" at the end.
An operation such as inputting a key indicating the end of the input such as the "er" key is required. By such an operation, the cursor moves to the character corresponding to the input code on the character list selection screen, and the character can be selected.

For example, in the case of the JIS kuten code, "1601" to "4751" are defined as the code range of the first level kanji, and "4801" to "8406" are defined as the code range of the second level kanji. Has been.

As described above, the code range is determined in advance according to the type of character, and the character selection process as described above is usually performed with the code range as the selection target. Therefore, when selecting a character by code input, it is necessary to set the code range as the current selection target. In this case, if a code outside the current code range is input, the corresponding character is not found and an error occurs. Therefore, it is necessary to change the code range and then perform the same operation as above.

[0006]

As described above, conventionally, when a character is selected from the character list selection screen by inputting a code, all the codes corresponding to the desired character are input, and further, " It has been necessary to perform a troublesome operation such as inputting a key indicating the end of input such as an "execute" key or an "Enter" key. Therefore, it takes a lot of time to obtain a desired character, and as a result, there is a problem that the document creation efficiency is reduced.

Conventionally, in the case of inputting a code outside the currently selected code range to select a character, the user must change the code range and then perform the same operation as described above. However, there was a problem that it was very troublesome.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a character selection method capable of improving the operability and reducing the burden on the user when selecting characters by code input. And

[0009]

[Means for Solving the Problems]

(1) According to the present invention, in the character selection method of inputting code information and selecting a character corresponding to the code information from a character list selection screen, numerical values of respective digits forming the code information are sequentially input from the upper digit. For each input, it is determined whether the input code information at the present time is a valid code, and if it is determined to be a valid code, the character corresponding to the input code information on the character list selection screen is displayed. Is to be selected.

According to such a method, when inputting code information, it is not necessary to input all digits, and
You can select the character by moving the cursor to the corresponding character in the character list selection screen without pressing the "Enter" key or the "Enter" key to indicate the end of the input. .

(2) Further, according to the present invention, in the character selection method of inputting code information and selecting a character corresponding to the code information from the character list selection screen, based on the code range set as a selection target. Display the above character list selection screen, and when the code information is input, it is determined whether the code information is within the code range. If it is determined that the code information is out of the code range, the input is performed. The code range is changed to include the code information, the character list selection screen is displayed based on the changed code range, and the character corresponding to the input code information is selected from the screen.

According to such a method, even when the code information outside the code range currently set as the selection target is input, the code range is changed according to the input code information, so that the code range by the user is changed. It becomes possible to select the corresponding character from the character list selection screen displayed based on the code range after the change, without requiring the change operation of.

Here, the control unit 13 controls the character list selection unit 14, the code input processing unit 15, and the code validity determination unit 16 to generate a code. Executes character selection processing by input.

The character list selection unit 14 displays a character list selection screen on the output unit 12, and selects a character corresponding to the input code from the screen. The code input processing unit 15 processes a code input operation, and here, inputs numerical values of each digit forming the code information in order from the upper digit,
For each input, the code validity determination unit 16 determines whether or not the code is a valid code, and when it is determined as a valid code, the code information is returned to the character list selection unit 14. The code validity determining unit 16 determines whether the input code information provided by the code input processing unit 15 is valid.

The storage unit 17 is composed of, for example, a memory such as a ROM and a RAM, and stores various kinds of information necessary for this apparatus,
Here, it has a code table 17a. Code information assigned to each character is registered in the code table 17a.

FIG. 2 is a view showing a character list selection screen in the first embodiment. For example, when the character list selection function is instructed by operating a function key provided in the input unit 11 or selecting an icon displayed on the display screen, the character list shown in FIG. The display unit 21 and the code input unit 22 are displayed. The character list display portion 21 is configured to display a list of characters corresponding to a predetermined number of codes. Code input section 22
Is a part where the user inputs code information.

When a character is selected by inputting a code on such a character list selection screen, first, the code information (5 in this case) corresponding to the desired character is input to the code input unit 22.
Enter the digits in order from the highest digit. This code input section 22
When the code information is input to, the cursor CL moves to the character corresponding to the input code information in the character list display portion 21. In this state, if the "confirm" key provided in the input unit 11 is pressed, the character can be input as a confirmed character in the document.

Next, the operation of the first embodiment will be described.
FIG. 3 is a flowchart showing a processing operation when selecting a character list in the first embodiment. Input information from the input unit 11 is sent to the control unit 13. The control unit 13 processes the input information and outputs the result to the output unit 12.

When the character list selection function is instructed through the input unit 11, the control unit 13 causes the character list selection unit 14 to operate.
Issue a processing request to. As a result, the character list selection unit 14
After displaying the character list selection screen as shown in FIG. 2 on the output unit 12, the following process is executed according to the key input of the input unit 11 (step A11).

That is, when the code information is input to the code input section 22 provided on the character list selection screen (step A12), the character list selection section 14 uses the input code information as the code input processing section. Send to 15. The code input processing unit 15 sequentially reads the code information sent from the character list selection unit 14 one by one character (numerical value) from the upper digit and outputs it to the code input unit 22 on the character list selection screen (step A13). .

At this time, the code input processing section 15 determines whether or not the input code information at the present time is a valid code through the code validity determining section 16 (step A14). The valid code is a code in which the corresponding character exists. In addition, for example, if a kuten code is input, it is determined whether or not the code is a valid code by determining the lower two digits as a point when at least three digits are input, and such a code is determined. This is performed by checking whether or not it exists in the table 17a.

As a result, when the input code information at the present time is determined to be a valid code (Yes in step A14)
s), the code input processing unit 15 returns the code information to the character list selection unit 14. As a result, the character list selection unit 14
Moves the cursor CL to the character corresponding to the code information in the character list display portion 21 and selects the character (step A15).

When a key for instructing the character confirmation is input from the input unit 11 (step A12),
The character list selection unit 14 notifies the control unit 13 of the character currently selected by the cursor CL, and ends the processing here (step A16). The control unit 13 performs processing such as inserting the character at a specified position in the document.

A specific example will be described with reference to FIG. For example, when the character list display unit 21 as shown in FIG. 4A is displayed, the user inputs the code input unit 2
It is assumed that the code information is entered in 2. It is assumed here that a 5-digit division code (upper 3 digits is a division, lower 2 digits is a point), for example, a code with a leading "0", such as the "\" code "00132". Information can be entered by omitting the "0".

As shown in FIG. 4B, when the user sequentially inputs the numerical values of the digits forming the code information from the upper digit, it is determined for each input whether or not it is a valid code. In this case, enter 3 in the code input section 22 such as "132".
When the digit code information is input, the lower two digits “32” can be defined as a point. Therefore,
At this point, it can be determined that the code "00132" having "1 (001)" as a ward and "32" as a point is input, and if it is present in the code table 17a, it becomes a valid code.

Since "00132" is a valid code,
As shown in FIG. 4C, the cursor CL moves to “\” corresponding to the code “00132” in the character list display portion 21. In this state, if the user presses the "confirm" key, "\" can be input in the document as the confirmed character.

If the user continues the code input operation without performing the confirmation operation, the above code determination is performed again. Then, when it is determined that the code is valid, the cursor CL moves to the corresponding character.

For example, in the example of FIG. 4B, if the user inputs "1321" followed by "1321", then the lower two digits "21" is set as a point, and "13" is set.
Code "013" with "(013)" as a ward and "21" as a point
21 "causes the cursor CL to move to a character (not shown) such as" I ".

In this case, the character list display section 21
Since the range in which characters can be displayed at once is determined,
By switching the screen, a code system including "I" is newly displayed in the character list display portion 21, and the cursor CL
Is set to "I". At that time, for example, if control is performed so that "I" comes to the same position as the previously selected position (here, "\" has been selected, the second line from the bottom), the line of sight of the user moves. Can be prevented to make it easier to find the next selected character.

(Second Embodiment) Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram showing the configuration of a document creation device having a code input function according to the second embodiment of the present invention. The present apparatus includes an input unit 31 and an output unit 3
2, a control unit 33, a character list selection unit 34, a code input processing unit 35, a code range determination unit 36, and a storage unit 37.

The input section 31 is composed of an input device such as a keyboard, and inputs data and gives instructions. Output unit 32
Are, for example, LCD (Liquid Crystal Display) and CRT
It consists of a display device such as (Cathode Ray Tube) and displays data.

The control unit 33 is composed of, for example, a microprocessor and controls the entire apparatus. Here, the control unit 33 controls the character list selection unit 34, the code input processing unit 35, and the code range determination unit 36 to generate a code. Executes character selection processing by input.

The character list selection unit 34 displays a character list selection screen on the output unit 32 based on the code range set as the selection target, and selects a character corresponding to the input code from the screen. The code input processing unit 35 processes a code input operation. Here, the code range determination unit 36 determines whether the input code information is within the currently set code range, and the determination is made. An instruction to change the code range is given to the code input processing unit 35 according to the result. The code range determination unit 36 includes the code input processing unit 3
It is determined whether or not the input code information given by 5 is within the code range currently set.

The storage unit 37 is composed of a memory such as a ROM or a RAM, and stores various kinds of information necessary for this apparatus.
Here, it has a code table 37a and a code range storage unit 37b. The code information assigned to each character is registered in the code table 37a.
Further, the code table 3 is stored in the code range storage unit 37b.
The code range currently set as the selection target in 7a is stored.

Since the display screen at the time of selecting the character list is the same as that shown in FIG. 2, its explanation is omitted here. Next, the operation of the second embodiment will be described.

FIG. 6 is a flow chart showing the processing operation when selecting a character list in the second embodiment. Input unit 3
The input information from 1 is sent to the control unit 33. Control unit 33
Then, the input information is processed and the result is output to the output unit 32.

When the character list selection function is instructed through the input unit 31, the control unit 33 causes the character list selection unit 34 to operate.
Issue a processing request to. As a result, the character list selection unit 34
2 displays a character list selection screen as shown in FIG. 2 on the output unit 32 based on the current code range stored in the code range storage unit 37b, and then performs the following processing according to the key input of the input unit 31. Execute (step B11).

That is, when the code information is input to the code input section 22 provided on the character list selection screen (step B12), the character list selection section 34 uses the input code information as the code input processing section. Send to 35. The code input processing unit 35 sequentially reads the code information sent from the character list selection unit 34 one character (numerical value) from the upper digit and outputs it to the code input unit 22 on the character list selection screen (step B13). .

At this time, the code input processing unit 35 determines through the code range determination unit 36 whether the input code information is within the current code range (step B).
14). The current code range is the current selection target range. For example, in the case of JIS ward code, the code range of the first level kanji is "1601" to "4751", and the code range of the second level kanji is "4801" to "8406".
Stipulated. Therefore, normally, when selecting characters by code input, it is necessary to set in advance which code range is to be selected, and when selecting a character outside that code range, change the code range. Is required. The determination as to whether or not it is within the current code range is made by checking the code range stored in the code range storage unit 37b.

As a result, when it is determined that the input code information is out of the current code range (Yes in step B14),
The code input processing unit 35 notifies the character list selection unit 34 of that fact. As a result, the character list selection unit 34 changes the code range of the code range storage unit 37b to the code range including the input code information (step B15). And
The character list selection unit 34 switches the display content of the character list display unit 21 based on the changed code range, moves the cursor CL to the character corresponding to the code information in the selected character range, and selects the character ( Step B15).

When the key for instructing the character confirmation is input from the input unit 31 (step B12),
The character list selection unit 34 notifies the control unit 33 of the character currently selected by the cursor CL, and ends the processing here (step B16). The control unit 33 performs processing such as inserting the character at a specified position in the document.

Here, a specific example will be described with reference to FIG. For example, the code range of JIS Level 1 Kanji ("1
It is assumed that the user inputs code information “1601” into the code input unit 22 as shown in FIG. 7A in a state in which “601” to “4751”) are set as the current selection target. It is assumed here that a 5-digit division code (upper 3 digits is a division, lower 2 digits is a point), and for example, a code "01601" of "A" has a leading "0".
The code information with "" can be entered by omitting the "0".

The input code information "160
1 ”is the current code range (“ 1601 ”to“ 475 ”).
1 ”). Therefore, as shown in FIG.
The cursor CL is moved to "A" corresponding to the code "01601" in the character list display portion 21 displayed based on the current code range. In this state, the user can confirm
By pressing the key, "A" can be entered in the document as the confirmed character.

Further, in this state, it is assumed that the user inputs code information "4801" into the code input section 22, as shown in FIG. 7C, for example. In this case, the code information “4801” is the current code range (“1601” to
"4751"), the code range is changed.

As a result, the code range of JIS second-level Chinese characters ("4801" to "8406") is set as the code range including the input code information, and FIG. ) The character list display portion 21 as shown in FIG.
The cursor CL is moved to the character "弌" corresponding to "1".

Even when the screen is changed due to such a change in the code range, as described in the first embodiment, for example, the same position as the previous selection position (here, "A" is selected). Therefore, if the control is performed so that the “string” is placed on the first line), it is possible to prevent the user's line of sight from moving and to easily find the next selected character.

In the first embodiment, the character selection process including the input code determination process and the character selection process including the code range changing process in the second embodiment are separately described. The configuration obtained by combining the first and second embodiments can be easily realized.
