Abstract

PURPOSE:To display all dead composite characters composed of dead codes and effective base characters so as to reduce misinput operation by making dead composition codes which can be inputted clear when a dead key is pressed during document creation. CONSTITUTION:When a key is pressed during the document creation, it is judged (S30) from a dead composition code table whether or not the key is the dead key and when it is judged (S32: Yes) that the key is the dead key, dead composition codes regarding all dead composite characters composed of the dead code generated with the dead key and effective base characters are obtained (S35) from the dead composition code table; and all the dead composite characters regarding the pressed dead key are displayed (S36) in a list display area on a liquid crystal display on the basis of the dead composition codes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus which, when a dead character code is input, displays a dead composite character using the dead character represented by the dead character code.

[0002]

2. Description of the Related Art Conventionally, in a document processing device having a dead key in a keyboard, when a dead composite character is input, when the dead key is pressed, the dead character indicated by the dead key pressed at a position other than the input position on the display screen. Is displayed, and when the character indicated by the character key pressed next can be combined with the dead character, the dead combined character obtained by combining the dead character and the character is displayed at the input position, and the dead character code and the character are displayed. The input character code is converted into a dead composite character code representing a dead composite character and is input.

Here, the dead key is not understood as a single character or symbol by itself, such as German umlaut "¨" or French axan silicon flex "^", such as A or O. Characters that are generally valid when combined with alphabetic characters, or
It is a general term for a key group for inputting a dead character as a symbol.

A code generated by pressing a dead key is referred to as a dead character code, and a code or a character that becomes a generally valid character when combined with a dead character code such as A or O is a valid base code. Alternatively, it is referred to as an effective base character, and a code formed by combining the dead character code and the base character is referred to as a dead composite code.

When inputting a dead composite character as described above, if a character key that cannot be combined with the displayed dead character is pressed, a buzzer or the like is activated to notify the operator of that fact. Performing error processing by performing error processing that sounds and prohibiting the input of non-synthesizable characters, and by displaying or printing dead characters and non-synthesizable characters on top of each other. In some cases, the input of characters that cannot be combined is permitted.

[0006]

However, when the operator presses a dead key, the next key usually presses a valid base character in each country. Therefore, there is very little demand for inputting a superposed character composed of a dead character and a character that cannot be combined. In this way, the input of non-synthesizable characters is often an input error by the operator, and if the input of non-synthesizable characters is allowed as in the latter case, the document processing device to which the spell check function is added does , Spelling errors occur and hinder smooth writing. In addition, in the document processing device to which the spell check function is not added, the operator is not notified of an input error, so that an incorrect character is input without being recognized by the operator.

When the input of non-synthesizable characters is prohibited as in the former case, the operator inputs a valid base character based on his / her own memory, so that an input error is likely to occur and the input is difficult. If you make a mistake, there is a problem that you cannot immediately enter a valid base character.

The present invention has been made to solve the above-mentioned problems, and when inputting a dead composite character,
An object of the present invention is to provide a document processing device that can prevent input errors.

[0009]

In order to achieve this object, a document processing apparatus according to the present invention comprises a text memory for storing at least one text file composed of a plurality of character codes, the character code and the dead character. A document processing device comprising: input means for inputting a code; and display means for displaying a character code stored in the text memory or a character corresponding to the character code input by the input means. Inputting by means of dead composite character storage means for storing the character code and dead composite character display data for displaying the dead composite character used by the dead character indicated by the dead character code on the display means in association with each other. Determining means for determining whether or not the generated code is a dead character code, and the determining means is a dead character code When the determination is made, a display control means for reading the dead composite character display data corresponding to the dead character code from the dead composite character storage means and displaying the dead composite character on the display means based on the dead composite character display data. I have it.

[0010]

The document processing apparatus of the present invention having the above structure is
When the code is input by the input means, the determining means determines whether or not the code is a dead character code. When it is determined that the code is a dead character code, the display control means causes a dead character code corresponding to the dead character code. The composite character display data is read from the dead character storage means and displayed on the display means.

The dead composite code group storage unit 22 stores a dead composite code group consisting of a plurality of dead composite code pairs related to dead character codes, for each dead character code, and at the end of each dead composite code group. A pair of data “0,0” is stored as an end code to distinguish it from the dead composite code group. That is, as shown in FIG. 3, at the end of the dead composite code group 22A related to umlauts, a pair of data "0, 0" is provided for distinguishing from the dead composite code group 22B related to Axan Silicon Flex.
Is stored. The dead composite code pair is composed of a base character corresponding to a dead character corresponding to a dead character code and a base character that can be combined, and a dead composite code corresponding to a dead composite character formed by combining the dead character and the base character. Become.

The pointer table 21 stores the start address of the dead composite code group associated with each dead character code stored in the dead composite code group storage unit 22. The dead composite code group storage unit 22 thus configured constitutes the dead composite character storage means of the present invention.

Next, the operation of the word processor 1 will be described with reference to FIG. FIG. 4 shows a flowchart of the editing process and the dead composite code input process executed by the control unit C. First, after the power is turned on and a predetermined initial process is executed, the process waits until any key is pressed in the key input waiting state (S30: No). When a key is pressed (S30: Yes), the type of the key is determined and various editing processes are performed.

The code entered by pressing the key is
Exists in the comparison table 20 of the composite code table 16B
The type of key pressed depends on whether or not
-5 is judged (S32), the code is compared
If it exists in the bull 20, that is, if the pressed key
If the type is dead key 5 (S32: Yes), the
The dead character code entered by pressing the
It is stored in the dead character code memory 18B and
No. in the comparison table 20
Ask for the stored dead character code, and
It is stored in the same position as the order in the table 21
Input the dead character by getting the starting address
Set the start address of the dead composite code group corresponding to the code
Ask (S34).

Next, the dead composite code pair is read from the start address obtained in S34 until the end code of the data "0,0" is read, and the display corresponding to the dead composite code in the read dead composite code pair is displayed. The font data is read from the ROM 16, and the font data is expanded in the composite code display buffer 18D and displayed in the list display area 70 displayed at a predetermined position on the liquid crystal display 8. Then, the cursor 71 is displayed at the head of the plurality of displayed dead composite characters (S3).
6). At this time, the pointer P of the pointer buffer 18C
T indicates the address obtained in S34, that is, the dead composite code pair located at the head of the dead composite code group corresponding to the input dead character code.

For example, when the umlaut key is pressed,
The code input by pressing the key is compared with the dead character code in the comparison table 20, the key pressed in the process of S32 is determined to be the dead key 5, and the first dead character code in the process of S34. Is obtained, the first address value of the pointer table 21 is read, and the dead composite code group 22A of the umlaut designated by the address value from the dead composite code group storage unit 22 is sequentially combined with the dead composite code pair. The font data corresponding to the dead composite code in the dead composite code pair that has been read is read from the ROM 16, and the dead composite character is displayed in the list display area 70 of the liquid crystal display 8 based on the font data in the process of S36. (See FIG. 6). Then, the cursor 71 is displayed at the leading dead composite character. Further, the pointer PT points to the dead composite code pair located at the head of the dead composite code group 22A.

As described above, when the dead key 5 is pressed, all the dead composite characters related to the pressed dead key are displayed in the list display area 70 of the liquid crystal display 8, so that the input dead composite characters can be recognized. Becomes extremely easy.

With a plurality of dead composite characters being displayed in the list display area 70, the dead composite code selection process is executed (S38). This dead composite code selection processing will be described with reference to the flowchart shown in FIG.

First, it waits until some key is pressed (S50: No). When the key is pressed (S50: Ye
s) The type of the key is determined and various processing is performed.

That is, if the cursor key 4 is pressed and the cursor 71 is movable (S64: Yes), the cursor 71 is moved up, down, left, or right according to the type of the pressed cursor key 4. And the pointer PT
Changes its value and indicates the dead composite code pair related to the dead composite character where the cursor 71 is located (S6).
6). Then, the process returns to S50.

On the other hand, the dead composite character is not displayed at the movement destination of the cursor 71 when the cursor key 4 is pressed,
When the cursor 71 cannot be moved (S64: N
o), the buzzer 32 is rung to notify the operator of this (S68). Then, the process returns to S50.

If the key pressed in S50 is the decision key 6, it is recognized that the dead composite character designated by the cursor 71 has been selected and decided (S54), and the pointer stored in the pointer buffer 18C is recognized. The dead composite code in the dead composite code pair designated by PT is stored in the text memory 18A (S56). When the processing of S56 ends, the display in the list display area 70 is erased,
After the dead composite code selection process (S38) is finished,
Return to the process of 30.

If the key pressed in S50 is the character key 3, the code input by pressing the character key 3 is the dead composite code group related to the dead character code stored in the dead character code memory 18B. It is determined whether or not the character key 3 pressed is the character key 3 related to the synthesizable base character by determining whether or not the character key 3 is stored in (S60). As described above, the base code is also stored in the dead composite code pair in the dead composite code group, and if the input character code is stored in the dead composite code group (S60: Yes), the dead composite code group is stored. It is recognized that the dead composite character corresponding to the dead composite code paired with the character code has been selected and determined in step S62, and the dead composite code paired with the character code is stored in the text memory 1 in step S56.
Store in 8A.

For example, the dead character code stored in the dead character code memory 18B is umlaut,
When the character key 3 of "a" is pressed, the character code of "a" and the base code are compared from the beginning of the umlaut's dead composite code group 22A, and the character code of "a" is the second from the beginning. Since it matches the base code "a" in the dead composite code pair, it is determined to be valid in S60. Then, in S62, it is recognized that the dead composite code of "a" with umlaut paired with the base code "a" is selected and decided, and in S56, the dead composite character code is stored in the text memory 18A.

Then, the display in the list display area 70 is erased, the dead composite code selection process (S38) is terminated, and the process returns to the process of S30.

On the other hand, if the input character code is not stored in the dead composite code group, it is determined that the character code is an invalid code that is not the base code (S60:
No), a buzzer sounds to inform that effect (S
68) and then the process returns to S50.

Further, when the cancel key provided on the keyboard 2 is pressed, the list display area 70 is immediately displayed.
Is erased, and the dead composite code selection process (S3
8) ends, and the process returns to S30. When any key other than the cursor key 4, the decision key 6, the character key 3, and the cancel key is pressed, it is determined that an invalid key has been pressed and the buzzer sounds (S68), and then S
It returns to the processing of 50.

In the process of S30, if the type of the input key is the edit end key (S40), the document storing process (S42) is performed and the document editing process is finished. If it is any other key, general document editing processing for various keys is performed (S44).

The control section C executes the above S32 to constitute the judging means of the present invention.
By executing 36, the display control means of the present invention is configured.

As described in detail above, in the word processor 1 of this embodiment, by pressing the dead key 5,
All the dead composite characters related to the dead key 5 pressed on the liquid crystal display 8 are displayed together with the cursor 71.
Then, the operator operates the cursor key 4 to move the cursor to a desired dead composite character to select the desired dead composite character, and presses the decision key 6 to enter the dead composite character to be input. The code is stored in the text memory 18A.

Therefore, the operator can surely input the dead composite character without error by the extremely easy method of pressing the cursor key 4 and the enter key 6 without depending on his own memory.

By looking at the dead composite characters displayed in the list, the user can very easily recognize the effective base character for the dead character associated with the pressed dead key, and the effective base character By pressing the character key 3, it is possible to reliably store the desired dead composite character in the text memory 18A.

In the word processor 1 of this embodiment, as a method for inputting a dead composite character, the cursor key 4 and the enter key 6 are pressed while the list of dead composite characters is displayed, or I pressed the character key, but I displayed a list of dead composite characters with numbers,
It is also possible to select and input a dead composite character by pressing the number keys.

In the word processor 1 of this embodiment, as shown in FIG. 6, the liquid crystal display 8 was large enough to display all dead composite characters at one time, but as shown in FIG. In the case of the small liquid crystal display 82 in which the dead composite characters cannot be displayed at one time, some dead composite characters are displayed in the display area 80, and the dead composite characters displayed in the display area 80 are switched by pressing the cursor key 4. It may be configured as follows.

[0047]

As is apparent from the above description, in the document processing apparatus of the present invention, when the dead key is pressed, the dead composite character relating to the pressed dead key is displayed on the display means, so that the operator can display it. It is possible to input a dead composite character while watching the dead composite character, and it is possible to reliably prevent an input error.
