Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a document processing apparatus used when creating a document.

[0002]

2. Description of the Related Art Generally, a document is created by using a writing tool such as a pencil and paper, but in recent years, a CRT (Cathode-Ra) operated by a computer, stored and controlled.
It is often created using an information processing device such as a document processing device capable of displaying characters on a display unit such as a y tube).

The above-mentioned information processing apparatus usually has a display unit having a display unit for displaying a document, a keyboard used for inputting character data and the like, and control of a display state of the display unit by an input key of the keyboard. The control unit stores character data and the like, and the character data input from the keyboard is output to the display unit while being stored in the character data storage area of the control unit to create a document.

That is, in the conventional information processing apparatus, as shown in FIG. 5, a character display area 52 for displaying a part of the character data group stored in the control unit on the screen with a predetermined number of characters and lines.
Is displayed on the display unit 51, the cursor 53 corresponding to the address of the character data storage area is output to the character display area 52, and the position where the cursor 53 is output (hereinafter referred to as the cursor position) is input from the keyboard. The document is created by outputting the character data.

When the created document is edited, the display screen of the character display area 52 is scrolled by moving the cursor 53 to a position beyond the upper and lower ends or the left and right ends of the character display area 52, and editing is required. When the edited portion, which is a sentence, is displayed on the screen, the character data is added, deleted, or corrected based on the cursor position.

[0006]

However, the above-mentioned conventional information processing apparatus has a problem that the editing efficiency may be lowered depending on the position of the editing portion.

That is, for example, when the edit portion is displayed on the screen at the upper end, the cursor 53 is moved to the edit portion for editing, but the sentence one line before the edit portion is not displayed on the screen. Therefore, it is not possible to grasp the context of the edited part. Therefore, in this case, the editing preparation work is required to move the cursor 53 to a position beyond the upper end of the character display area 52, scroll the display screen, and move the editing portion to the central position of the character display area 52.

The above-mentioned editing preparation work is indispensable when the editing portion is located at the upper and lower ends and the left and right ends of the character display area 52, and is located near the upper and lower ends and the left and right ends. Even if it is, it is an important task to fully understand the context of the edited part. However, the editing preparation work is different from the original editing work such as addition, deletion, and correction of character data, which is necessary for understanding the sentence, and the edited portion is located in the central portion of the character display area 52. If it is, it is unnecessary. As a result, in the conventional information processing apparatus, the editing efficiency is lowered as the editing portion is located on the end side of the character display area 52.

In addition, the conventional information processing apparatus has a cursor 5
When the display screen is scrolled in the opposite direction by 3, the cursor 53 needs to be moved from the upper end to the lower end, for example, so that the time required for scrolling is delayed. The time required for this scroll is closely related to the editing efficiency because it is proportional to the time for moving the edited portion to a predetermined position, and in the conventional information processing device, even when scrolling in the opposite direction, Editing efficiency has decreased.

Therefore, as shown in FIG. 6, there is a model of the information processing apparatus which can limit the scroll range by designating a specific range of the character display area 52. In the case of this model, scrolling is possible. It is possible to shorten the time required for editing and improve editing efficiency. However, the scrolling of the display screen is performed when the cursor 53 is moved out of the scroll range. Therefore, when the edit portion is located at the end of the scroll range, it is necessary to understand the sentence. It is necessary to perform the editing preparation work described above, and the editing efficiency is reduced.

As described above, in the conventional information processing apparatus, since the cursor movement range and the scroll range match,
There is a problem that the editing efficiency is lowered because the context cannot be grasped depending on the position of the editing portion. Therefore, it is an object of the present invention to provide an information processing device capable of always grasping the context of an edited part.

[0012]

In order to solve the above-mentioned problems, the information processing apparatus of the present invention is capable of editing the edit portion of the display screen based on the cursor position, and has the following features. ing.

That is, the information processing apparatus has a character display area, which is a scroll range of the display screen, and a cursor movement area, which is a movement range of the cursor and scrolls the display screen when the cursor moves outside the area. Have The cursor moving area is set within the character display area.

[0014]

With the above arrangement, since the cursor movement area, which is the movement range of the cursor, is set in the character display area, which is the scroll range of the display screen, when the cursor moves beyond the cursor movement area. The display screen of the character display area can be scrolled.
Therefore, the information processing device can confirm the text before and after the edit portion existing at the cursor position from the character display area around the cursor movement area. The editing preparation work for moving to the center position of the display area is unnecessary, and the editing efficiency is constantly improved.

Further, in this information processing apparatus, when the display screen is scrolled in the opposite direction by the cursor, it can be performed by moving the cursor from one end of the cursor moving region to the other end, so that both ends of the character display region are moved. The time required for scrolling is shortened and the editing efficiency is improved compared to the case of doing it.
