Abstract

PURPOSE:To change a character which is already inputted into a character having a close character code on a word processor. CONSTITUTION:A character code change part 3 increases a character code at a cursor position by one in response to the depression of an increment key 1b on a keyboard 1 and decreases the character code by one in response to the depression of a decrement key 1c to change the character at the cursor position into a character having a last or following character code. Further, the character code is changed cyclically to the head when increased from the tail or to the tail when decreased from the head so that the result of the increase or decrease does not exceed a range stored in a character code storage part 4, thereby changing characters in the range of stored character codes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device such as a word processor, and more particularly to a function for changing an input character.

[0002]

2. Description of the Related Art In a word processor, as a method of inputting so-called symbols that are not present on a keyboard, an input method using a division number has been known.

Further, a symbol group inputting method has been conventionally performed in which symbols having similar properties are divided into groups and a desired one is selected from a series of symbols in the group.
And such an example is, for example, SWP-7 manufactured by Sanyo Electric.
00, page 78 of the basic operation manual.

The conventional symbol group input method will be described in detail below.

First, the user presses the symbol group key to display the symbol group menu (FIG. 4) which is a list of group names. Next, use the cursor keys to select a desired one, for example, "Suji" and highlight it, and press the execute key. Then, the first symbol list shown in FIG. 5A is displayed, and then the conversion symbol is pressed to display the next symbol list shown in FIG. 5B. Therefore, the symbol can be input by pressing the number key "1". The group name "Suji" once selected is stored, and then the symbol list of FIG. 5B is directly displayed only by pressing the Kanji dictionary key. Therefore, after inputting, when inputting next, press the Kanji dictionary key to display the symbol list of FIG. 5B, and then press the number key “2”. The display of the menu can be omitted.

[0006]

In the conventional symbol group input, when another symbol group is selected from the symbol group menu of FIG. 4 after the symbol input, the character string is directly displayed by using the Kanji dictionary key. List of symbols (Fig. 5
It becomes impossible to display (b)). For this reason,
Next, when inputting a symbol, the symbol group key must be pressed again and the symbol group menu (FIG. 4) must be displayed again.

In addition, each time the kuten number is input, it is necessary to enter a four-digit number each time, and the user must remember the kuten number of the desired character, or if not, search for it from a material such as a manual. It was necessary to input, and the user was burdened.

As described above, a complicated operation is required when changing a symbol which has not been input on the keyboard to another symbol.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a character processing device that can easily change an input symbol to another symbol having a similar property.

[0010]

According to the present invention, a display means capable of displaying a cursor indicating a character input position, a text storage means for storing a character code of a character displayed on the display means, and the cursor are provided. Cursor moving means for moving, character change instructing means for instructing to change the character at the cursor position, and a character code at the cursor position from the text storing means in response to an instruction from the character change instructing means. And a character code changing means for taking out the character code and replacing the character code with the next or previous character code.

Further, it is provided with a storage means for storing at least the head and end character codes of a predetermined symbol group, and the character code changing means cyclically within the range of the character codes stored in the storage means. The character code is replaced.

[0012]

According to the present invention, it is possible to change to a character having an adjacent character code by moving the cursor to an input character or symbol and instructing the character change.

Further, by cyclically replacing the character codes among the character groups having similar character codes, it is possible to easily change the character code to another character in the same group as the input character.

[0014]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a block diagram showing the configuration of the present embodiment. Reference numeral 1 is a key for inputting a character, a cursor key 1a for moving a cursor, an increment key 1b for instructing a character change, and A keyboard provided with the decrement key 1c, 2 a control unit for processing data and controlling the whole, 3 a character code changing unit for replacing the character code at the cursor position with the previous or next character code, and 5 storing the character code A text storage unit 6 is a display control unit that outputs the contents of the text storage unit 5 to the display unit 7.

Further, in the character processing apparatus of this embodiment, a continuous character code is given to a series of symbols having similar properties, for example ,.

The operation of this embodiment will be described below with reference to FIGS.

When a symbol is input using the symbol group input method described above, and then another group “parentheses” is selected from the menu of FIG. 4 using the same method and one of the parentheses is input. To do. Then, it is necessary to change the symbol to after the input of the parentheses. In this case, first, the cursor is set to with the cursor key 1a (step 1), and the increment key 1b is pressed to give an instruction to change to the next symbol (step 2). Then, the character code changing unit 3 is activated to check whether or not there is a character code in the text storage unit 5 at the cursor position (step 3). If there is no character code here, that is, if no character is input at the cursor position, the character code changing unit 3 does nothing through the NO route in step 3. If the character code exists, the process proceeds to step 4 through the YES route in step 3, the character code is taken out from the text storage unit 5 at the cursor position and is substituted into the internal variable i (step 4).
Then, it is judged whether the input is the increment key or the decrement key (step 5).
Proceed to step 6 through the ES path and set the internal variable i to 1
Increment. Finally, the value of the internal variable i is written back to the text storage unit 5 at the cursor position as a character code (step 13). Then, the display control unit 6 displays the contents of the text storage unit 5 on the display unit 7 (step 14), and can confirm that the symbol has changed to.

On the contrary, in order to change the symbol to, the cursor is set to by using the cursor key 1a (step 1), and the decrement key 1c is pressed to give an instruction to change to the previous symbol (step 2). Then step 3,
Steps 4 and 5 proceed through the NO path in step 5 to step 7 to decrement the internal variable i by 1.
Then, proceeding to steps 13 and 14, is displayed instead of the symbol on the display unit 7.

Here, the case of using the conventional symbol group input will be described. Since another group is selected after the symbol input, when the symbol is input, the symbol group key is moved after the cursor is moved. , The selection key of the symbol group menu, the conversion key, and the numeric key “1” have to be touched four times, which requires an extremely troublesome operation as compared with the single touch of the present embodiment.

By the way, in this embodiment, the character code storage unit 4 shown in FIG. 3 stores the character codes at the beginning and end of each symbol group. In the case of the above-mentioned "Suji" group, the character codes at the beginning and the end are stored. Then, the character code changing unit 3 further performs the following processing.

That is, after changing the internal variable i in step 6 or 7 of FIG. 1, the process proceeds to step 8 and then to step 9 shown in FIG. Then, the value of the internal variable i is compared with the contents of the character code storage unit 4,
It is checked whether the character code is before the first character code (step 9). If so, the process proceeds to step 10 and the last character code stored in the character code storage unit 4 is assigned to the internal variable i. Otherwise, go to step 11. Next, the value of the internal variable i is compared with the content of the character code storage unit 4 to check whether it is the character code next to the last character code (step 11). If so, step 1
Proceeding to 2, the leading character code stored in the character code storage unit 4 is assigned to the internal variable i. Otherwise, go to step 13.

Therefore, when the cursor is set on the symbol and the increment key 1b is pressed, the symbol is displayed on the display unit 7, and when the cursor is set on the symbol and the decrement key 1c is pressed, A symbol is displayed on the display unit 7.

[0024]

According to the character processing apparatus of the present invention, a desired character can be easily generated based on an already-input character or symbol without repeatedly using a complicated input method such as input with a division number or symbol group. Input can be made, and the burden on the user can be reduced.
