Abstract

PURPOSE:To obtain an exact deleting operation by executing a pre-deleting work, in case a cursor on the screen is in the next position of a character of the trail end of a generated document, and deleting a character on the cursor, and also, preventing the pre-deleting work from being executed, in case a deletion is executed on the way of the document. CONSTITUTION:A position for inputting a character onto a display screen 1 for displaying a generated document is displayed by a cursor, and at the time of deleting an inputted character, based on this cursor as a reference, in case the cursor on the screen 1 is in the next position of a character of the tail end of the generated document, a pre-deleting work for deleting the character of the tail end is executed by a deleting key 10. Also, in case the cursor is moved on the way of the generated document and a deletion is executed from on the way of its document, the character on the cursor is deleted, and also, when the screen has become the same screen state as the pre-deleting work by this deleting work, a warning is given so that the pre-deleting work is not executed. In such a way, the deleting work can be executed efficiently, and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for deleting characters from an inputted document in an intersection circle creation device such as a typewriter or word processor.

(Prior Art) A conventional function and method for deleting characters of an inputted document and text in document creation\A will be explained with reference to FIGS. 6 to 11.

FIG. 6 shows an example of an input device in a conventional text creation device, and this input device includes a display (hereinafter referred to as drawing) 1 for displaying input text,
Numeric keys 2, character keys 3 for hiragana, katakana, alphabet, etc., delete key 4 for deleting the character at the cursor position on the screen, and text 1 that the cursor has entered
When the cursor is in the position t next to the rightmost character, the front delete key 5 is pressed to the left of the cursor, that is, to delete the rightmost character, and the front delete key 5 is used to select and instruct the execution of various functions such as moving the cursor. It is equipped with 6 function keys. The function to delete the entered text is to delete the text on the drawing using the delete key 4 and previous delete key 5! s11! It will be held in

First, using the delete key 4 to delete the character on the cursor and delete the right part from the middle of the text is explained using Figure 7. '', and if you press the delete key 4 once while the cursor 7 is at a character position in the middle of the text, the character on the cursor will be deleted, and the characters to the right of the cursor 7 will be moved one character to the left. Ru.

That is, the basic function of the delete key 4 is to delete the character on the cursor and shift each character of the text to the right of the cursor one character apart.

In this way, if the delete key 4 is pressed multiple times, characters will be deleted one after another, and if the delete key 4 is pressed with no characters on the cursor, a warning sound will be emitted and the state will not change.

A 70-chart (procedure) for performing this operation is shown in FIG. The program for executing this flowchart is written in the IC memory (RO
M>, etc., and is stored in a microprocessor (CP
Overall control is executed by reading a program in memory based on instructions from U).

To explain the flowchart in FIG. 8, a key scan operation is performed (step S1), it is checked whether the delete 1-1 key has been pressed (step S2), and if it is not the delete key, another key process is executed (step S3). , in the case of a delete key, it is checked whether there is a character on the cursor (step S4).

If there is a character on the cursor, delete that character (step S5), then delete each character in the text to the right of the cursor.
Shift to character distribution (step So) and return to step S1. On the other hand, if there is no character on the cursor in step S4, a warning sound is emitted to notify the operator of a malfunction (
Step 87), then return to step S1.

Next, the state of previous deletion using the previous deletion key 5 is shown in FIGS. 9 and 10.
This will be explained using figures. FIG. 9 shows deletion from the end of the text, and FIG. 10 shows deletion from the middle of the text to the left.

As can be seen from these figures, the basic function of the previous delete key 5 is to delete one character to the left of the cursor and shift each character in the text to the right of the cursor by one character.

A flowchart for carrying out this operation is shown in FIG. Here, the same steps as above are given the same numbers, and instead of step S2, it is checked whether the previous delete key has been pressed (step 520), and instead of step S4, it is checked that there is a character to the left of the cursor. (step 840), and then deletes one character to the left of the cursor in place of step S5 (step 350), and further,
The cursor is shifted to give one character (step S
51〉. The rest is the same as above.

The purpose of providing both the delete and pre-delete functions as described above is that during continuous input, the cursor is always placed at the next position 211 of the rightmost character in the document (i.e., the unattended part). This is because it is possible to quickly respond to both the deletion of a character in the middle of an intersection when collecting Ia, and the deletion of the final input character during the above-mentioned continuous manual input.

However, according to such conventional deletion methods, the operator has to use two different keys, the deletion key 4 and the previous deletion key 5, to perform the deletion.
However, it had some drawbacks in terms of operability.

In other words, for example, if you make an input error while inputting ASCIST continuously, the input error is not an operation of the delete key, but an operation of the previous delete key, which does not match the normal sense of ``If you make a mistake, delete it.'' This was a factor that prevented improvements in the efficiency of input work.In other words, normally, during continuous input, a mistake is often noticed immediately after pressing a key, but after realizing the mistake, it is difficult to reflexively press the delete key. Instead, it is necessary to determine whether the previous delete key has been pressed.However, making such a key selection determination tends to interrupt one's thinking and lead to a decrease in input efficiency.

(Object of the Invention) The present invention solves the above-mentioned problems, and is a method for deleting characters in a created document, in which an accurate deletion operation can always be obtained by operating only one type of deletion key when deleting input stream text. The purpose is to provide

(Structure of the Invention) The present invention provides a method for creating a created document in which the position at which characters are input is displayed as a cursor on a display screen displaying the created document, and the input characters are deleted by operating a delete key using this cursor as a reference. In the character deletion method, if the cursor on the screen is at the position following the last character of the created text, use the delete key above to perform the deletion operation before deleting the last character, and move the cursor to the created document. If you move to the middle of the document and use the delete key above to delete from the middle of the document, the characters on the cursor will be deleted, and a warning will be issued if the execution of this deletion task results in the same screen state as the previous deletion task. , the reason is that it does not enter the pre-deletion process.

With this method, whether it is deleting an input error during continuous input or deleting a character on one cursor in the middle of text during editing, it is possible to handle the deletion by operating one and the same deletion key.

(Example) FIG. 1 shows an example of an input device for implementing the method of the present invention,
The main body of the device is equipped with one deletion key 10 in place of the two types of deletion keys and pre-deletion key described above, and this deletion key 10 is provided with the same function as the two types of keys described above, and the flowchart (procedure) described later is provided. Based on this, the positional relationship between the inputted characters and the cursor on the screen is determined by a microprocessor (CPU) in the main body of the device, and the functions are used appropriately. Further, a display (screen) 1, other numeric keys 2, character keys 3, and function keys 6 are provided in the same manner as described above.

Next, the deletion method of the present invention will be explained using FIGS. 2 to 4.

Figure 2 shows a case where the character on the cursor is deleted and the right part of the text is continuously deleted from the middle of the text. Each time the delete F-10 is pressed, the character on the cursor 7 is deleted, and each text on the right side of the cursor 7 is deleted. The character is shifted one character to the left. When the delete key 10 is depressed in a state where there is no character on the cursor 7,000, that is, there is no character to be deleted, a warning sound is emitted to notify the operator of a malfunction, and the state does not change. This operation is the same as that shown in FIG. 7 described above, although the keys used are different.

FIG. 3 is an example of deleting a character from the end of a text, and shows what happens when a character to the left of the cursor 7 is deleted (that is, previous deletion) when the user notices it immediately after inputting it during continuous input.

That is, when the cursor 7 is located at the next character position at the end of the text and the delete key 10 is operated in this state, the previous deletion operation is automatically performed. This operation is the same as that shown in FIG. 9 described above, although the keys used are different.

Figure 4 is an example of deleting the character on the cursor, with the delete key 1
Each time 0 is pressed, the character on the cursor 7 is deleted, and each character in the text to the right of the cursor 7 is shifted to the left by one character. The final result of this illustration is the 10th
It is the same as the one in the figure, but the keys are different and the actions in between are different.

In the method of the present invention, as shown in the final result of Fig. 2 above, the text is continuously deleted from the middle of the text, and when all the text above and to the right of the cursor has been deleted, the end of the text shown in Fig. 3 above is deleted. Although the screen state is the same as the state of the pre-deletion work from , the major feature is that the pre-deletion work does not automatically start at this point, but a warning sound is emitted as described above.

A flowchart for carrying out the above operations is shown in FIG. The operation will be explained below according to this flowchart. First, the mode is set to [previous delete 1 (step n1), a key scan is performed (step n2), and it is checked whether the delete key 10 has been pressed (step rN).
. Here, when another key is pressed, the corresponding key is processed (step n4), and when the delete key 10 is pressed, it is next checked whether there is a character on the cursor (step n5).

Here, if there is a character on the cursor, proceed to step n8, delete one character on the cursor, and roughly shift each character in the text to the right of the cursor one character to the left (step n8).
7), update the mode to "delete" (step n8), and then return to step n2 above. Repeat this until there are no more characters on the cursor, move from step n5 to step n9, check what the mode is, and set [1 to 1.
If it is the 1 mode, a vI warning tone is emitted in step n14. By executing these steps, the deletion operation shown in FIG. 2 or 4 can be obtained.

Next, if the mode setting in step n1 is [Previous Delete, 1], and if it is determined in step n5 that there is no character on the cursor, the process moves from step n9 to step n10, and the character is placed to the left of the cursor. If there is a character to the left of the cursor, delete one character to the left of the cursor (step n11), shift the cursor one character to the left (step nt2), and set the mode to "previous deletion". Then, the process returns to step n2. By repeating this operation, if there are no more characters to the left of the cursor in step n10,
A warning sound is emitted at step n%. By performing these steps, the pre-delete operation shown in FIG. 3 above is obtained.

In this way, for all deletion operations, the same deletion key operation is used to delete the character to the left of the cursor in response to an input error during continuous input, that is, to delete the previous deletion and to delete the character on the cursor during editing. Therefore, unlike in the past, the user does not have to worry about whether to use the previous delete key or the delete key, and can execute the delete function quite naturally without interrupting his/her thinking, contributing to improved work efficiency.

What's more, even if the screen becomes the same as the pre-deletion state from the state in which text is being deleted midway through, a warning will be issued instead of inadvertently entering the pre-deletion process.
It is also effective in preventing malfunctions.

(Effects of the Invention) As described above, according to the deletion method of the present invention, when the cursor on the screen is at the position next to the last character of R in created sentence 1, the last character can be deleted by operating the delete key. When deleting from the middle of the document, the character on the cursor is deleted, and the same screen state as the former pre-deletion operation is executed. Even if , the pre-delete does not automatically start and a warning is issued, so by operating one type of delete key, you can perform the normal pre-delete when inputting continuously, and the pre-delete at the cursor when editing. Both functions for deleting characters are automatically used properly,
Therefore, when performing deletion work, the operator does not need to judge the type of key to operate, and can perform deletion work efficiently without interrupting his/her thinking.
This can greatly contribute to operability.
