Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus having a block editing function.

[0002]

2. Description of the Related Art Conventionally, a document creating apparatus, which is a Japanese word processor, is provided with various editing functions such as copying, inserting, and deleting. This editing function performs editing processing such as copying, inserting, and deleting a character string in the range designated by the cursor in the created document data.

Among the editing functions is a block editing function for executing an editing process on a range of blocks designated by a cursor over a plurality of lines. In this block editing function, the character string of the rectangular range (block) in which the range to be edited extends over a plurality of lines is copied, inserted, or deleted.

By the way, it is useful to have a function of extracting a designated block in a document and inputting and editing character data within the range of the block independently of the document.
With the conventional block editing function, the editing contents are limited, and it is impossible to edit the character data independently of the main document.

[0005]

The conventional block editing function is limited to performing editing processing such as copying, inserting, and deleting a character string of a designated block. It would be useful to have a function of inputting and editing character data independently of the main document within the range of this block.

An object of the present invention is to realize a block editing function for executing the editing process of character data in a designated block independently of a main document, and consequently improve the document editing function. The object of the present invention is to provide a document creation device that can do this.

[0007]

According to the present invention, in a document creating apparatus having a block editing function, a block designating unit for designating a block which is a designated range in document data stored in a document memory unit, and a block designating unit. This is an apparatus provided with a block memory means for storing character data input within a range and a block editing means.

[0008]

In the present invention, the block editing means expands the character data input in the block designated by the block designating means into the block memory means. Further, after the block editing process is completed, a process of transferring the character data expanded in the block memory means to the document memory means is executed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a main part of the document creating apparatus according to the embodiment.

This apparatus is a microprocessor (CP) that executes control of the entire apparatus, document creation processing, editing processing, and the like.
U) 1, a keyboard 2, an input control unit 3, a ROM 4, a document memory 5 and a block memory 9.

The keyboard 2 is provided with a cursor key 2a, a block edit key 2b and the like in addition to various character keys. The input control unit 3 converts various key input signals input from the keyboard 2 into key codes. ROM4 is C
It is a read-only memory in which a program of PU1, character font data, and the like are stored in advance.

The document memory 5 is a buffer memory for storing the created document data. The block memory 9 is
It is a buffer memory for storing the character data input within the range of the block designated by the keyboard 2. The block memory 9 has a storage capacity of, for example, one page or less.

Further, the present apparatus comprises a display section 6, a display controller 7 and a video RAM 8. Display 6
Is controlled by the display controller 7, and the video RAM
The display data expanded in 8 is displayed. Video RAM8
Is character font data (display data) corresponding to the character code stored in the document memory 5 or the block memory 9
Is a display read / write memory for storing
Next, the operation of the embodiment will be described.

First, as shown in FIG. 2, in the normal character editing mode, the CPU 1 executes kana-kanji conversion processing for a character string input from the keyboard 2 and stores it in the document memory 5 (step S1). Further, the CPU 1 executes various editing processes (for example, copy, insert, delete, move, etc.) on the input character data in response to an instruction from the keyboard 2 to edit the edited character data (character code string).
Is developed in the document memory 5 (step S2).

The CPU 1 reads character font data corresponding to the character data expanded in the document memory 5 from the ROM 4 and expands it in the video RAM 8. The display controller 7 outputs the character font data from the video RAM 8 to the display unit 6 and displays the character data in the document memory 5 on the screen of the display unit 6 (step S3).

When the block edit key 2b of the keyboard 2 is operated (YES in step S4), the CPU
1 activates the block edit mode. In the block edit mode, the CPU 1 displays the block edit mode menu on the screen of the display unit 6, as shown in FIG.
When the number "6" is input by operating the keyboard 2, "input" in the block edit mode is designated.

In accordance with the block edit mode menu displayed on the screen, the cursor key 2a of the keyboard 2 is operated to specify the start and end points of the block, as shown in FIGS. 3A and 3B. Then, the range of the block that is the target of the block editing process is determined (step S
6). As shown in FIG. 4A, the CPU 1 controls the cursor 41 to move only within the set range of the block 40 (step S7).

Next, when the character key of the keyboard 2 is operated (YES in step S8), the CPU 1 develops character data (character code) corresponding to the character key in the block memory 9 (step S9). The CPU 1 reads character font data corresponding to the character data expanded in the block memory 9 from the ROM 4 and expands it in the video RAM 8. The display controller 7 outputs the character font data from the video RAM 8 to the display unit 6 and displays the character data in the block memory 9 on the screen of the display unit 6 (step S10). As a result, as shown in FIG.
The input character string is displayed within the range of the designated block 40. Further, the CPU 1 displays the moving cursor 41 within the designated block 40 (step S11).

In this way, when the character data is input within the designated block 40 and the editing process such as copying and deleting is completed (YES in step S12), the CPU 1
Transfers the character data stored in the block memory 9 to the document memory 5 (step S13). As a result, the character data edited within the designated block 40 is inserted into the main document data loaded in the document memory 5.

In the present invention, the block memory 9 is provided in addition to the document memory 5 for expanding the main document data, so that the character data input within the range of the designated block 40 is stored in the block memory 9. Be expanded.
Therefore, it is possible to execute the editing process of the character data within the range of the block 40 independently of the main document data.

At this time, by executing control such that the cursor 40 moves only within the range of the block 40, the block editing process accompanying the movement of the cursor 40 can be performed without interfering with document data other than the block 40. Becomes In other words, the character editing process within the designated block 40 can be executed in the same manner as the normal character editing process. Therefore, it is not limited to the conventional editing processing such as copying, inserting, and deleting the character string of the specified block, and it has a high function to input and edit the character data independently of the main document. The block editing function of can be realized.

[0022]

As described above in detail, according to the present invention, the character editing process in the designated block can be performed independently of the main document. Therefore, it is possible to realize a high-performance block editing function equivalent to a normal character editing process. As a result, the document editing function can be improved.
