DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a word processor and a computer capable of creating a document, and more particularly to a document processing apparatus having an editing function using a backward key.

[0002]

2. Description of the Related Art Conventionally, in this type of document processing apparatus, there is known a method of processing a function of a backward key by deleting a character to the left of a cursor, filling a subsequent character string, and moving the cursor one character to the left. I have.

FIG. 5 is a flowchart showing a conventional reverse key function process. The description of the flowchart shown in this figure will be described with reference to the explanatory diagram of FIG. 6 shown below.

FIG. 6 is an explanatory view showing a display example of a conventional reverse key function process. As shown in this figure, for example,
In insert mode, the character string "ABCDE or Kikukeko"
Is input and the character to be erased is "O", the cursor is positioned at the position of the next character "?" (Step 51), and when the backward key is input (step 5).
2) The character "o" to the left of the cursor is deleted and the character string below "ka" is packed (step 53). The cursor is also moved one character to the left along with the character "" (step 5).
4). As shown in FIG. 6 (1) becomes "Ayuue or Kikukeko". Subsequently, when the backward key is input, steps 52 to 54 are repeated, and “e” is erased.
The character string is clogged by two characters, as shown in FIG.
String is "ABC or Kikukeko".

[0005]

However, in the conventional document processing apparatus, the editing processing function of the backward key can perform only the same function processing in the insertion mode and the correction mode.
For this reason, since the character to the left of the cursor is deleted and the character string after that is packed, there is a problem that the format of the character string always collapses.

The present invention has been made in view of the above circumstances, and in order to provide an easier-to-use operation environment, a document processing apparatus having a backward key editing function of different specifications between the insertion mode and the correction mode. Is to provide.

[0009]

According to the present invention, in FIG. 1, in a document processing apparatus having an insertion mode and a correction mode for editing a character string, the mode switching means 101 switches between the insertion mode and the correction mode. The input means 102 inputs a character string and indicates a position of a character for editing with a cursor. The storage unit 103 stores the character string input from the input unit 102. Editing means 104 edits the stored character string. The display unit 105 displays the input character string and the character string being edited on a display screen. Reverse instruction means 10
Reference numeral 6 is linked to the cursor and instructs the editing means 104 to delete one character to the left of the cursor. This retreat instructing means 106
When an instruction for deleting a desired character is issued from the editing unit 104, if the mode at the time of editing is the insertion mode,
Delete the character to the left of the cursor, move the cursor one character to the left while filling the subsequent character string, and in correction mode, delete the character to the left of the cursor, replace the deleted character with a space, and move the cursor Move one character to the left.

Therefore, the backward instructing means 106 operates in conjunction with the cursor to delete the character at the left of the cursor.
When the instruction is given to the user, the specifications are different between the insertion mode and the correction mode. In particular, since one character deleted in the correction mode can be replaced with a space, the character string of the document does not move, so the operation is easy to use for layout and the like. Environments can also arise.
