2. Description of the Related Art FIG. 5 shows how a conventional word processor corrects a document. As soon as the character to be modified is deleted from the document (FIG. 5A), the deletion result is reflected in the document data display (FIG. 5B), and then a new character is input. This result will be reflected soon. (FIG. 5 (c)) Japanese Patent Laid-Open No. 17508/1985 for saving layout and inserting / deleting blank characters when modifying a document by a word processor
9 and the like are known. In these conventional technologies, the document layout information is saved, and the layout collapse after the document is corrected is avoided by inserting and deleting a space. Is not covered. Block editing for designating a block to be erased and inserting a system space and deleting a system space after editing is known in Japanese Patent Laid-Open No. 4-118750 and the like. For the block editing function that does not require operations such as, do not change the original document data and layout when modifying the character string, and do not update the document data and layout when deletion and modification are confirmed. Absent.

[0003]

When a conventional word processor deletes characters to be corrected, those characters disappear immediately, the document data is rewritten, and the display layout changes. Therefore, there is a problem that it is difficult to grasp the correction position, erroneous correction input is likely to occur, and the image of the corrected document is difficult to grasp. In addition, since a series of operations of deleting and inserting the correction character string exist as individual functions, even if the correction operation is stopped at the time of deleting and inserting, the document before correction will not There is a problem that has been changed.

The present invention has been made in view of the above circumstances, and when a document is corrected on a display device, when a character to be corrected is deleted, it is first replaced with a blank or an underlined blank and displayed. As a result, a new character string can be input while maintaining the display layout regardless of the number of characters of the character string to be newly input.

[0005]

According to the invention described in claim 1, in a document processing apparatus for processing an input document, a correction means for correcting a character or the like forming a part of the document, and the correction. Responsive to the means, a replacement means for replacing a character or the like to be corrected with a blank portion, and a candidate character such as a correction character newly input in the blank portion while leaving at least a part of the blank portion in the blank portion And a confirmation means for confirming the displayed candidate characters and the like, and a deletion means for responding to the confirmation means and for deleting the blank display of at least a part of the blank portion. And a document processing device having a document correction function.

According to the second aspect of the invention, in the document processing apparatus for processing the input document, the correction means for correcting the characters or the like forming a part of the document, and the correction means in response to the correction means. Replacement means for replacing a character or the like to be replaced with a blank portion, and display means for displaying a candidate character such as a correction character newly input in the blank portion while leaving at least a part of the blank portion in the blank portion , A confirmation means for confirming the displayed candidate characters, a confirmation prohibiting means for not operating the confirmation means, and a candidate for deleting the display of the candidate characters displayed on the display means in response to the prohibiting means. A document processing apparatus having a document correction function, characterized in that it comprises character erasing means and erasing means responsive to the deciding means and erasing at least a part of the blank display of the blank part.

[0007]

According to the present invention, in an information processing apparatus having a document display, input, edit function, etc., when a document is modified, the deleted character is first replaced with a blank, and then a new character is input from above to confirm. After that, the blank part is deleted and the correction is reflected in the whole document and display. If the correction has not been confirmed, a cancel operation is performed to return to the state before the start of the correction.

Therefore, when the document is corrected on the display device, when the character to be corrected is deleted, it is displayed by replacing it with a blank or a space with an underline so that it can be displayed regardless of the number of characters of the newly input character string. It is possible to input a new character string while maintaining the layout of. Therefore, since the correction location can be known, there is an effect that the correction can be made by mistake in the document, especially if too many characters are deleted or the input position of a new character is incorrect. When inputting characters with the pen, you must first trace the part you want to correct with the pen, leave it blank, and then enter from above.You can correct the character as if you were correcting it with the correction pen. It can be done and there is no discomfort. Also, the work of deleting and inserting at the time of correction is one function, and since the actual document data is updated after the work is confirmed, if the correction work is stopped but the correction is not completed, the original document data No changes have been made and there is less chance of accidental destruction of document data.
