Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a document creation / editing device such as a word processor, a desktop publishing system (DTP), and a personal computer having a document creation / editing function.

[Conventional technology]

The above-described document creation apparatus generally includes an input processing means such as a keyboard for inputting various characters, control information, and the like, and an editing processing means for creating and editing a document based on the input information; Document registration means for registering and saving the edited document on a floppy disk or hard disk is provided.

Also, even if a stall (inoperable state) occurs in the system during document creation / editing, there is a need to create or edit a document so that the document being created / edited can be recovered to the maximum extent. A memory such as a hard disk that does not lose its stored information even when the power is turned off when the processing is interrupted and the power is cut off by interrupting the process at a timing (when the key input is not longer than a predetermined time or when a certain unit of data is changed). Some are provided with automatic temporary storage processing means for automatically writing and temporarily storing the data in a temporary storage.

[Problems to be solved by the invention]

However, in a conventional document creation / editing apparatus equipped with such automatic temporary storage processing means, a message is displayed when the temporary storage processing is started to notify the user that data is being stored, and during that time, a keyboard or the like is used. Any input from the input means was invalidated.

Therefore, the number of times of writing and the processing time of the document data become a problem, and if the number of times of writing is large or the time is long, the operability is reduced, and the efficiency of document creation / editing is deteriorated.

The present invention has been made in view of the above points, and has as its object to prevent the above-described automatic temporary storage function of a document being created and edited from affecting the operation performance.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a memory which does not lose its stored information even if the processing is interrupted during the creation or editing of a document by the editing processing means and the power of the created and edited document is cut off. In the document creation / editing apparatus provided with automatic temporary storage processing means for automatically temporarily storing data, when an input is made by the input means during the temporary storage processing by the automatic temporary storage processing means, the temporary storage processing is stopped. An automatic temporary saving process suspending means for restarting the document creation / editing process by the editing process means is provided.

(Operation)

In the document creation / editing apparatus according to the present invention, even if the text or the like is input from the input unit even during the automatic temporary saving process of the document being created / edited, the process is immediately stopped and the document creation / editing process is restarted. Therefore, the operation performance does not decrease.

FIG. 1 is a block diagram mainly showing a functional configuration of the control unit 10 according to the present invention.

The control unit 10 includes a key input determination unit 21, an editing processing unit 22, an editing document display unit 23, and a document registration unit 24 necessary for document creation and editing, an automatic temporary storage processing unit 25, and an automatic temporary storage start-up. Section 26, automatic temporary storage stop section 27, and initial menu display section
28, temporary storage determination unit 29, and temporary storage document recovery / deletion unit
It has 30.

The key input determination unit 21 determines that any key of the keyboard 1 has been operated, sends the determination signal to the automatic temporary storage activation unit 26 and the automatic temporary storage stop unit 27, and receives the input. The character code or function code of the key is determined and sent to the edit processing unit 22.

When the editing is completed, the instruction is given. When the initial menu display unit 28 (described later) displays a message for restoring an automatic temporary storage document on the CRT 4 and a character key of “0” or “1” is input, it is given, respectively. The temporarily stored document recovery / deletion unit 30 is notified.

The editing process 22 includes various processes related to document creation and editing, such as character string generation, kana-kanji conversion, correction, deletion, insertion, line feed, and page break, according to the character code and function code from the key input determination unit 21. Perform

The editing-in-document display section 23 displays the document being edited and edited by the editing processing section 22 and the unconfirmed character string, various guidance information, and the like.
Display on T4.

The document registration unit 24 is stored in its internal memory (the main memory 12 in FIG. 2) when a document registration instruction from the keyboard 1 is input to the edit processing unit 22 via the key input determination unit 21. The created and edited document data is transferred to the HDD 8 with a document name, written to a hard disk, and registered.

The automatic temporary storage processing unit 25 starts automatic temporary storage when a key input determination signal is not output from the key input determination unit 21 for one second, for example, during creation or editing of a document by the edit processing unit 22 (no key input). It is started by the section 26, and at that time, the internal memory of the editing processing section 22 (the main memory of FIG. 2)
The document data being created and edited stored in 12) is automatically transferred to the HDD 8 and written to the hard disk for temporary storage.

When the document data is written to the hard disk by the automatic temporary storage process, all the document data is rewritten each time, but the data is written in the storage format of the internal memory as it is, so the writing process is completed much faster than in the case of document registration. be able to.

When the automatic temporary storage canceling unit 27 inputs a key input determination signal from the key input determination unit 21 while the automatic temporary storage processing unit 25 is performing the temporary storage processing, the automatic temporary storage processing unit 25 executes the temporary storage processing. The document processing and editing processing by the editing processing unit 22 is restarted.

Also, at the end of editing, the key input determination unit 21 determines the input of the editing end key and notifies the temporary storage document recovery / deletion unit 30 of the input. Let it be erased.

When the system is powered on (ON), the initial menu display unit 28 displays the initial menu on the CRT 4 when the system starts up. At this time, the temporary storage determination unit 29 is activated, and the hard disk drive of the HDD 8 is activated. It is determined whether or not there is an automatically temporarily stored document. If it is determined that there is an automatically temporarily saved document, an automatic temporarily saved document restoration message as shown in FIG. 4 is displayed on the CRT 4.

When "0" is input in this state, the temporary storage document recovery / deletion unit 30 reads out the automatic temporary storage document stored in the HDD 8, transfers it to the edit processing unit 22, and stores the internal temporary storage in the internal memory. In this case, the document whose editing has been interrupted is restored, and the editing process can be continued. After that, the HDD 8 is made to delete the automatic temporary storage document.

If “1” is input, the temporary storage document recovery / deletion unit 30 does not perform the above-described suspended document restoration processing, and
Causes the automatic temporary storage document to be deleted.

FIG. 5 is a flowchart showing the processing of the microprocessor 14 shown in FIG. 3 at the time of document creation and editing according to this embodiment.

This routine starts when "create new document" or "update document" is selected by the work many.

Then, it is first determined in step 1 whether or not there is a key input, and if there is a key input, the process proceeds to step 2 to determine whether or not the key is a key to be automatically temporarily stored.

Keys that are not the keys for automatic temporary storage include cursor movement, scroll, beginning of sentence, end of sentence, next page, previous page, beginning of line, end of line, page recall, movement amount change, and input mode designation keys. Various character keys and the like are automatic temporary storage target keys.

Here, if a key that is not the key to be automatically temporarily stored is input, the process proceeds to step 4 to execute the editing process. If the key is a key to be automatically temporarily stored, step 3 is executed.
Then, the temporary storage flag is set in the counter also serving as a timer, and then the process proceeds to step 4 to execute the editing process.

Thereafter, if the end of editing is not instructed in step 5, the process returns to step 1 to repeat the above processing. When the end of editing is instructed, the automatic temporary storage document stored on the hard disk is deleted in step 6 to enter the editing end state, and the system prepares for subsequent processing such as document registration.

If it is determined in step 1 that there is no key input, the process proceeds to step 7 to determine whether 1 second has elapsed. If not, the counter is decremented (-1), and step 1 → step 7 → step Repeat the loop of 1.

Here, the counter for detecting that there is no key input for one second is also used as the flag memory of the temporary storage flag. When the temporary storage flag is reset, this counter is set to "7FFFH". Set to “100H”. Then, this value is decremented in step 8,
When it reaches "0", it is judged that 1 second has passed and step 10
Proceed to.

In step 10, an automatic temporary storage process is performed in which the document data being created and edited in the internal memory (RAM) is written to an automatic temporary storage file on the hard disk (HD).

Then, it is determined in step 11 whether or not the writing of all data has been completed. If completed, the temporary storage flag is reset (to "7FFFH") in step 12, and the process returns to step 1.

If writing of all data has not been completed in step 11, the process proceeds to step 13 to determine whether or not a key input has been performed.
If there is no key input, the process returns to step 10 to continue the automatic temporary saving process. However, if there is a key input, the automatic temporary saving process is stopped, the process returns to step 1, and the editing process according to the key input is immediately resumed. The automatic temporary storage process is controlled by the document being created and edited and its temporary document. Writing to the file for automatic temporary storage is performed in units of a certain unit, for example, a unit of characters, ruled lines, edit control signals, etc., and a certain number of characters. When the writing of the data of this one unit is completed,
The presence or absence of a key input in step 13 is determined. If there is a key input, the automatic temporary storage processing is stopped, and when writing of all data is completed, a complete automatic temporary storage document is secured.

Note that even when the automatic temporary save process is forcibly stopped by key input, the data that has been automatically temporarily saved last time is stored without being destroyed.

The determination as to whether or not the key is an automatic temporary storage target key in step 3 is a determination as to whether or not the data needs to be automatically stored, and is performed when an undetermined character is determined and when editing and proofreading are changed. Alternatively, it may be determined that data needs to be saved.

Further, the automatic temporary storage document is not limited to a hard disk, and may be stored and stored in any memory such as a floppy disk or a non-volatile memory that does not lose its stored contents even when the power is turned off.

The functions of this embodiment described above will now be summarized and described.

According to this embodiment, a document being edited is automatically saved in text editing and layout editing.

When the system is stalled during editing, the next time the power is turned on, a message as shown in FIG. 4 is displayed so that the user can select whether to restore or delete the stored document. This stored document is registered in an area different from the conventional temporary storage area.

When the power is turned off by turning off the main switch of the system, the power is prevented from being turned off during disk access, and the automatic temporary saving process can be completed without causing the disk to be destroyed.

In the area editor, the area data being edited is not automatically temporarily stored.

Automatic Temporary Saving of Text Editing After normal character input, automatic temporary saving is performed when there is no input for about 1 second.

 After the unconfirmed character is confirmed, automatic temporary storage is always performed.

When "end after registration" or "end without registration" is selected in <edit end>, the stored document is deleted.

If no character is input at the start of editing, automatic temporary saving is not performed.

Automatic temporary saving is not performed when the cursor is moved, scrolled, the beginning of a sentence, the end of a sentence, the next page, the previous page, the beginning of a line, the end of a line, the page recall, the change of the moving amount, or the input of each key for input mode designation.

≪Restrictions≫ Undetermined characters are not automatically temporarily saved.

The automatic temporary storage processing takes about 1 to 2 seconds, but if a key input is made during the processing, the automatic temporary storage processing is stopped. However, the automatic temporary storage process is not stopped when an undetermined character is input.

Automatic temporary saving is not performed for the input of characters and ruled lines during the editing function by pressing the function key.
However, at the end of the editing function (when returning to the normal character input state), automatic temporary saving is always performed.

Automatic temporary saving of layout edit Automatic temporary saving is performed when the arrangement of characters is changed due to character editing or area rearrangement.

When "end after registration" or "end without registration" is selected in <edit end>, the stored document is deleted.

≪Restrictions≫ Do not save temporarily when entering characters in the guidance due to insertion / correction.

Automatic temporary saving is not performed in the beginning of sentence, end of sentence, next page, previous page, beginning of line, end of line, page recall function.

〔The invention's effect〕

As described above, even during the automatic temporary saving process of the document being created and edited according to the present invention,
When a character or the like is input from the input means, the processing is immediately stopped and the document creation / edit processing is restarted, so that the operation performance does not deteriorate.

Therefore, without affecting input operations in any way,
If the system is stalled during editing, the document being edited at that time can be restored to the maximum.
