Description

[Detailed Description of the Invention] [Summary] In a document creation device, in order to copy all characters existing between, for example, one character input earlier at a certain input point of time, the above-mentioned arbitrary method is used. It has an echo copy preprocessing section that specifies the first character to be copied at the time of input, an echo copy instruction section that instructs echo copy, and an echo copy processing section that executes the echo copy. It is disclosed that text etc. inputted into the computer can be easily copied.

[Industrial application field]

The present invention relates to a document creation device having an echo copy function, and more particularly to a document creation device having an echo copy function that allows a document that has been inputted immediately before to be easily copied.

[Conventional technology]

Conventionally, in document creation devices such as Japanese language creation devices and program creation devices, characters, symbols, words, or sentences input using a key input device are displayed on a display device and stored in a document memory. It is planned to continue.

In such a document creation device, the following means are employed as means for copying an already input portion. That is, the first method is called a previous line copy, in which the entire immediately preceding line is copied. The second method is to specify the upper left point and lower right point when multiple lines are enclosed in a rectangle, and then
This is to specify another arbitrary location and copy to the specified location.

[Problem that the invention seeks to solve]

In the case of the above-mentioned first means, the copy range is set in units of rows, and flexibility is low. In the case of the second method, it is necessary to enclose the copy range in a rectangular area and then specify the copy location.

For the above, at a certain point while inputting,
There may occur cases where it is desired to copy the entire text from an already input character, symbol, word, or sentence up to the relevant point, after the relevant input point. That is, as shown in Figure 4A, when characters are input, the user notices that the previously inputted part is repeated, and as shown by the dotted line in Figure 4B, it is desired to copy the previously inputted part. There are many cases.

[Means for solving problems]

The present invention solves the above-mentioned problems, and FIG. 1 shows a basic configuration diagram of the present invention.

In the figure, numeral 1 is a processing device, 2 is a key input device,
Reference numeral 3 denotes a display device, and 4 and 4' are respective document memories. 4 represents the state before the processing according to the present invention is performed, and 4' represents the state after. Reference numeral 5 represents an echo copy preprocessing section, 6 an echo copy instruction section, and 7 an echo copy processing section.

In the document creation device, characters, symbols, etc. are input using the key input device 2, and the results are stored on the document memory 4. The contents on the document memory 4 are then displayed on the display device 3.

For example, when the echo copy is activated while the character "K" is input as shown in the figure, the echo copy preprocessing unit 5 generates a "character or symbol" that serves as a reference for searching the processing range of the echo copy. or a word or sentence (letter in the case shown)" is identified as the letter "K." The echo/copy instruction section 6 displays an echo/copy instruction on the key input device 2, for example.
A copy key is provided, and when the key is pressed, echo copy processing is started, assuming that echo copy has been activated. The echo copy processing unit 7 searches the range to be processed by echo copy and selects "α, β, γ".
Therefore, the data is copied onto the document memory 4 as shown in the memory 4', and correspondingly displayed on the display device 3.

[Effect]

Assume that an echo copy instruction is issued from the key input device 2 while characters are being input into the document memory 4 as shown in FIG. At this time, in the case of the illustrated embodiment, the echo copy preprocessing unit 5
extracts the character "K" that was input when the echo copy instruction was issued, and saves the character "K" on the document memory 4.
trace back to the location where the same letter "K" is found. This makes it clear that the echo copy target range is "α, β, γ" and its length (number of bytes).

From this state, the echo copy processing section 7 copies the document onto the document memory 4 as shown in the memory 4'. Further, this result is displayed on the display device 3.

〔Example〕

FIG. 2 shows a processing configuration of an embodiment of the present invention, and FIG. 3 shows a processing flow of an embodiment of the invention.

In Fig. 2, the symbols 2, 3, 4, 4', 5,
6 and 7 correspond to FIG. 1, 8 is a document memory address register, 9 is a source address register for echo copy search, 10 is a comparison processing means, and 11 is an echo copy range length. It represents the length (number of bytes) register that indicates the length.

The operation will be described below with reference to the flowchart shown in FIG.

When an echo copy instruction is issued from the key input device 2, the echo copy instruction section 6 detects this and issues an instruction to execute the echo copy.

As a result, the echo copy preprocessing unit 5
generates in the document memory address register 8 (D register) the address (on the document memory 4) of the character input immediately before the echo copy instruction.

Then, the contents of register 8 are transferred to source address register 9 (S register).

Also, preparations are made by clearing the contents of the length register 11 (L register).

Next, the echo copy processing unit 7
Subtract 1 from the contents of address register 9,
Point to the character to be input to the comparison processing means 10 (the character immediately before the character "K").

On the other hand, the comparison processing means 10 is supplied with the character "K" (in the case of the character shown on the address pointed to by the register 8).

The character at the address pointed to by the register 9 is supplied to the comparison processing means 10.

Comparison is performed in comparison processing means 10.

If they do not match, the contents of the length register 11 are incremented by 1 and the process returns to the above processing.

If they match, set the contents of registers 8 and 9 to plus 1, respectively, in order to reproduce the starting position where the echo copy should be performed, and change the contents of length register 11 from the address pointed to by register 9. The length indicated by
The data is copied onto the document memory 4 (as shown in 4').

Although the processing is performed as described above, the following modifications can be adopted, and it goes without saying that the present invention includes these modifications.

〔Effect of the invention〕

As described above, according to the present invention, it becomes easy to copy the previously inputted part during inputting, so that the operational efficiency in document creation is improved.
