Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device having a backward function in a system for creating and printing texts, such as an electronic word processor.

[Conventional technology] With the conventional backtracking function, no matter where the cursor was located on the character, the character under the cursor was detected and the character immediately before that character was erased. Even when it was behind a character, the character in front of it was erased. As a result, unexpected characters sometimes disappeared.

[Problems to be Solved by the Invention] An object of the present invention is to provide a function that can reliably determine the character to be erased when erasing the character in front of the cursor.

[Means for Solving the Problems] A document creation device of the present invention includes an input means for inputting and editing a sentence, a cursor display means for indicating a position to be edited, and a display device for displaying a position in front of the cursor during inputting the text. A correction means capable of erasing characters, a means for detecting the cursor position with respect to the character boundary, and a backward function that is the correction means, if the cursor is not at the normal position with respect to the character, It is characterized by comprising a correction means that is changed to the position of.

[Operation] The backward function of the present invention detects the position of the cursor on the character, and when the cursor is behind a full-width character, when the key with the backward function is pressed,
Corrects the cursor position to the character boundary position, and if the cursor is at the character boundary position, erases the previous character.

[Example] 3 shows an example of a retraction function according to the invention;

FIG. 1 shows a keyboard used in the present invention, and when key button 11 is pressed, a backward function is activated. FIG. 2 shows a screen when text is being input. 21 is the cursor position. FIG. 3 is a flowchart showing the processing of the backward function according to the present invention, and shows a case where the cursor is located at position 21 in FIG. 2 as a specific example.

When key button 11 is pressed, since there is a character under the cursor (51), it is determined whether the cursor is at a character boundary position (32). In the case of 21, the cursor is located behind the character and is not at the boundary position of the character, so the cursor is moved to the boundary position (34) and the process ends. Figure 4 shows the screen when finished. 41 becomes the cursor position at this time.

At step 32, if the cursor is located at a character boundary position as shown at 41 in FIG. 4, the previous character is erased (33) and the process ends. FIG. 5 shows the screen at this time. 51
is the cursor position at this time.

If there is no character under the cursor at step 61, the cursor is moved forward one position (35) and the process ends.

FIG. 6 shows a flowchart of the process of detecting the cursor position 32 in FIG. Indicate the case.

Here, the cursor position has data in half-width units, so
The 71 position in Figure 7 is the 3rd digit, and the 81 position in Figure 8 is the 2nd digit.
Become the digit.

First, start with the half-width "
・" is taken out (61). A counter for comparing digit positions is set to 1 (62). Comparing the counter and the cursor position (63), 1 in the counter is 3 at the cursor position.
Or, since it is smaller than 2, set the character size of the half-width "・", which is the data extracted in 61, to 1 (64), add this to the counter, set it to 2 (65), and add it to the next character data. is taken out (66). Here, the degree counter and cursor position are again compared (63). In the case of position 81, since the counter is 2 and the cursor position is coincident with 2, this process is terminated with the information that it is at the character boundary (67). In the case of position 71, the counter is still smaller, so add 2 (64), which is the size of "match", to the counter and make it 4 (65), and take out the next data "same" (
66). Here, when the counter and the cursor position are compared again (63), the counter is 4, which exceeds the cursor position 3 of 71, so this process is terminated with the information that it is not at the boundary (6B).

This function has been made clear from the above explanation of the operation, but whereas in the past there were cases where it was not possible to reliably determine the character to be erased, with the present invention, when it is difficult to determine, the character to be erased can be erased by moving the cursor. , characters to be erased can be determined reliably, and unexpected characters are no longer erased.

[Effects of the Invention] According to the present invention, characters to be erased can be reliably determined in the backward function.
