Description

Description: Object of the Invention [Industrial Application Field] The present invention relates to a data editing device for editing by temporarily calling data stored in a memory by a command such as deletion or copy.

[Prior Art] Generally, a data editing device such as a word processor has a copy function of copying an arbitrary area of a text on a screen to another position in a text and a deletion function of deleting an arbitrary area of a text on a screen. And so on. In practice, such a function is executed by temporarily storing data to be copied or deleted in a work area in the internal memory.

Furthermore, as a useful function when the user wants to use the data deleted by the deletion function again, or when he wants to copy some identical data using the copy function,
There was "paste". This paste function is to call up data temporarily stored in the work area by a command such as deletion or copy and restore the data to an arbitrary position.

[Problems to be Solved by the Invention] However, the conventional technology has the following problems, and further improvement is desired. That is, (1) Even if the operator attempts to restore data to an arbitrary position by using the paste function, after performing various operations after using a function such as copy or delete, the data stored in the work area is lost. It became unclear whether this was the case, and there was a problem that the paste function could not be used.

(2) Further, when similar data obtained by slightly correcting data in an arbitrary area of a copy source is to be copied to another plurality of areas, a plurality of the data of the copy source are initially prepared by a paste function. Then, it is necessary to add the correction to each data, so that the editing work is complicated and the accuracy of the edited data is low.

The present invention has been made in view of the above problems, and can confirm and correct data in a work area stored by a function such as copy or delete. As a result, it is possible to reduce editing work of an operator and to reduce edit data. It is an object of the present invention to provide a data editing device capable of improving accuracy.

[Means for Solving the Problems] To achieve the above object, a data editing apparatus according to the present invention comprises a display M3 for displaying data and an external operation as shown in the basic configuration diagram of FIG. Input means M9, and storage means having a data area M2 and a work area M5.
M1, a display unit M4 for displaying at least a part of the edit target data stored in the data area M2 on the display M3 as display target data, and the display target data based on an area instruction operation by the input unit M9. Is written in the work area M5 of the storage means M1, and at the time of the writing, if the number of pasted data already written is a predetermined number, the oldest pasted written data is written. A work area writing unit M6 for writing new paste target data after erasing the target data, and displaying the paste target data written in the work area M5 on the display M3 based on an operation by the input unit M9. Work data display means M8, the display M3 in the work data display means M8
Input data to the paste target data displayed in
A change is made based on the editing operation by M9, and further, the changed paste target data is written as new paste target data in the work area M5 of the storage unit M1. If the number is a predetermined number, a change / hold unit M10 that writes new paste target data after erasing the oldest paste target data that has been written, and the change / hold unit M10 that has not been changed or has not been changed. A data area writing unit M7 for writing the paste target data displayed on the display M3 on the work data display unit M8 at a position on the display target data designated by an instruction operation by the input unit M9.
And that it is provided with.

[Operation] In the data editing apparatus of the present invention configured as described above, the work area writing unit M6 may be configured to display the display object based on an area instruction operation by the input unit M9, for example, an instruction of a copy source area or an instruction of a deletion area. The new paste target data specified in the data is written to the work area M5 of the storage unit M1, and at the time of the writing, if the pasted target data already written is a predetermined number, the oldest written data is written. After deleting the paste target data, new paste target data is written.

Therefore, a predetermined number of the latest paste target data is always automatically accumulated in the work area M5 separately from the data area M2.

The work data display unit M8 can display the updated paste target data stored in a predetermined number on the display M3 based on the operation of the input unit M9.

Therefore, it is easy to determine what paste target data is stored in work area M5, and selection is easy.

Further, the change / hold means M10 is provided with a work data display means M8.
, The paste target data displayed on the display M3 can be changed based on the editing operation by the input means M9. The paste target data changed by the change / hold unit M10 is written by the data area writing unit M7 at the position on the display target data specified by the instruction operation of the input unit M9.

Therefore, it is not necessary to accumulate in the work area M5 all the paste target data having different changes in advance.
One piece of paste target data is displayed on the work data display means M8, the change is made by the change / hold means M10, and then the display target specified by the instruction operation of the input means M9 on the data area writing means M7. By performing writing at a position on the data, the paste target data can be easily changed, and can be immediately added to an arbitrary position of the edit target data.

In addition, the paste target data changed by the change / hold unit M10 is written as new paste target data in the work area M5 by the change / hold unit M10. If the number is a predetermined number, the oldest data to be pasted that has been written is deleted, and then new data to be pasted is written.

For this reason, the changed paste target data is stored in the work area M5 as new paste target data, so that both the changed paste target data and the unchanged paste target data can be reused by selection, which is efficient. Paste work is possible.

That is, the data to be pasted is displayed on the work data display means M8, the change is made by the change / hold means M10, and then the display object indicated by the instruction operation on the input means M9 is made on the data area writing means M7. While a series of operations of writing to a position on the data is repeated a plurality of times, the common common point needs to be edited only once. In addition, since data before each change and data changed in a series of operations are stored within a predetermined number as paste target data, reuse of the paste target data before each change and paste before the change are also performed. Different changes to the target data are easy,
This is an extremely efficient editing operation.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

This embodiment is a word processor as a data editing device having various functions such as deletion, copy, and paste,
FIG. 2 is a block diagram showing a schematic configuration of the word processor.

As shown in the figure, the word processor of this embodiment includes a keyboard 1 for inputting characters and editing instructions, a display device (CRT display) 3 for displaying characters and figures, a flexible disk drive 5 as an external storage device, characters and figures. 7 using a daisy-wheel type print, and an electronic control unit 10 connected to these devices for controlling input, editing, and printing of a document. The electronic control unit 10 is configured as an arithmetic and logic operation circuit centered on a well-known CPU 11, ROM 12, RAM 14, and the like, and receives a video RAM 15 for storing image data such as characters and figures to be displayed on the CRT display 3 and an input from the keyboard 1. And a flexible disk drive controller 18 for controlling the flexible disk drive 5 to read and write data, a printer output port 20 for outputting print data to the printer 7, and the like. The RAM 14 as the storage means M1 includes a data area 14a for storing a part of a sentence stored in the flexible disk drive 5, a work area 14b for temporarily storing data for various arithmetic processing, and the like. . The video RAM 15 has a so-called dual-port RAM configuration, and can be accessed by a CRT controller 22 provided independently of the CPU 11. Display means 4, work data display means M8 and change / hold means
The CRT controller 22 as the M10 has a CRT display 3
The content of the video RAM 15 is repeatedly read at a period determined by the scanning frequency of the image data, and is displayed on the CRT display 3. Therefore, data written in a predetermined area of the video RAM 15 by the CPU 11 is immediately displayed on the CRT display 3.

The keyboard 1 as the input means M9 has a character key 31 for inputting characters, ten function keys 33 for printing a document, etc., and four cursor keys for moving a cursor.
35 (Up cursor key 35U, Down cursor key 35D,
Left cursor key 35L, right cursor key 35R), four editing keys 37 (delete key 37D, copy key 37C, paste key 37P, etc.) for performing various document editing such as deletion, copy, and paste, and a character key 31 A control key 39 for inputting a print pause code or the like when pressed in combination is provided.

The operator can input a document by touching the character key 3 and press the edit key 37 as necessary, thereby selecting various functions such as deletion, copy, and paste to edit the document. Further, the created document can be written to a flexible disk set in the flexible disk drive 5 via the flexible disk drive controller 18. Further, by pressing the print key 33P, it is possible to output to the daisy-wheel type printer 7.

Next, a copy process and a paste process executed by the electronic control device 10 will be described. These processes are performed in ROM1
The program stored in 2 is executed by the CPU 11, and the copy process is performed when the operator presses the copy key 37C, and the paste process is performed when the operator presses the paste key 37P.

FIG. 3 is a flowchart showing the copy processing program. When the copy key 37C is depressed and the processing is started, first, as shown in FIG. 3, an instruction for a copy source area is received (step 100). Subsequently, it is determined whether or not the number of data stored in the work area 14b by copying, deleting, or the like before this processing exceeds 10 (step 11).
0). If it is determined in step 110 that the number of data is greater than 10, the oldest stored data is deleted (step 120), and then the generation management data described in each data in the work area 14b is deleted. One generation down (Step 13
0), the data in the data area 14a corresponding to the copy source area specified in step 100 is stored in the work area 14b as the latest data (step 140). On the other hand, if it is determined in step 110 that the number of data is 10 or less, step 1
Steps 130 and 140 are executed by skipping step 20. After the execution of step 140, subsequently, a copy destination instruction is received from the position indicated by the cursor (step 150), and the video R
The work area 14 is displayed at the position indicated by the cursor in AM15.
Insert the latest data stored in b (step 1
60) The data is inserted into the data area 14a at the position indicated by the cursor (step 170). Thereafter, the processing exits to "EXIT" and ends this routine once.

Next, the paste processing will be described with reference to the flowchart of FIG.

When the paste key 37P is depressed, the processing shifts to the paste processing routine shown in FIG. 4, and the execution position of the paste processing is read from the position indicated by the cursor (step 20).
0). Subsequently, the text after the position indicated by the cursor in the video RAM 15 is moved backward, the latest data stored in the work area 14b is inserted into the movement area and displayed on the CRT display 3 (step 210). Thereafter, the sentence in the video RAM 15 is further moved, and the number of generation management data stored in the work area 14 is displayed on the CRT display 3 via the video RAM 15 (step 220). Subsequently, it is determined whether the input data input from the keyboard 1 is data from the down cursor key 35D, data from the ENTER key 31E, or data from other keys (step 230). The down cursor key 35D is
When the latest data in the work area 14b displayed at 210 is not desired, the key is pressed by the operator, and when it is determined that the data is from the down cursor key 35D, the next generation in the work area 14b is performed. The previous stored data is displayed as the next candidate (step 240), and the process returns to step 230.

On the other hand, if it is determined in step 230 that the input data is data from the ENTER key, the displayed data is stored in the work area 14b as the latest data (step 250).
Thereafter, the latest data is determined at the display position in the video RAM 15 (step 260), and is inserted into the execution position in the data area 14a (step 270). afterwards,
The processing exits to “EXIT” and ends the processing of this routine once.

On the other hand, if it is determined in step 230 that the input data is neither the data from the down cursor key nor the data from the ENTER key, the input data is for correcting the data displayed on the CRT display 3. Then, edit (correct) the data in the video RAM 15
The work to be performed is executed (step 280). Subsequently, as in steps 110 to 130 in FIG.
It is determined whether or not the number of data stored in b is greater than 10 (step 290). If the data is greater than 10, the oldest data is deleted (step 300) and the generation described in each data is deleted. Lower management data by one generation (Step 31)
0), the data edited in step 280 is stored as the latest data in the work area 14b (step 320). On the other hand, if it is determined in step 290 that the number of stored data is 10 or less, the processing in step 300 is skipped, and the processing in steps 310 and 320 is executed. Thereafter, the processing of steps 260 and 270 described above is executed, the processing exits to “EXIT”, and the processing of this routine is temporarily terminated.

Therefore, in the copy processing configured as described above,
When copying the data of the restoration source area in the text to the copy destination, the copied data is temporarily stored and held in the work area 14b, and the number of data to be stored can be stored up to 10 and each generation is managed. Have been like.
The number of data to be held may be arbitrarily set according to the use condition of the memory. Note that the word processor of this embodiment is configured to store the processing data in the work area 14b as described above even in the deletion processing, but a detailed description thereof will be omitted. On the other hand, in the paste processing configured as described above, the data stored in the work area 14b in the copy processing or the deletion processing is inserted and displayed at the execution position indicated by the cursor on the CRT display 3, and furthermore, Desired data can be selected from the stored data, and the data can be corrected. For this reason, the operator can check and correct data stored in the work area 14 in the copy processing and the deletion processing, thereby reducing the editing work and improving the accuracy of the edited data. be able to. In the present embodiment, step S100
To S140 correspond to the processing as the work area writing means M6, steps S200 to S240 correspond to the processing as the work data display means M8, and steps S230, S280 to S320 change and
This corresponds to the processing as holding means M10, and steps S150 to S17
0 or steps S230, S260 and S270 correspond to the processing as the data area writing means M7.

In the above-described embodiment, the storage data in the work area 14b is inserted and displayed at the position indicated by the cursor in the text on the CRT display 3. Instead, for example, a display specially provided outside the text is displayed. You may comprise so that it may display on an area.
