Abstract

PURPOSE:To enable an operator to see a document before update even after updating the stored document by adding discrimination information for distinction between document data before editing and that after editing to these data to store them while preserving original document data before editing at the time of reading out and editing stored document data to store edited document data again. CONSTITUTION:A CPU 10 discriminates whether document data stored in a document memory 14 is a new document or not. When it is discriminated that this document data is not a new document, that is, it is an edited document, the latest version number under the present directory in a document file disk 18 is retrieved, and the version number obtained by (the latest version number) +1 and the date counted by a clock 22 are added to present document data in the document memory 14, and this data is additionally stored correspondingly to the present directory in the document file disk 18. That is, the new version is generated, and document data having the old version number is preserved as it is. Thus, it is stored in the document file disk 18.

2. Description of the Related Art In recent years, documents are often created and printed out using a word processor supplied as an application of a personal computer or as a dedicated machine. Also, this created document is
It can be stored in a document file disk such as a hard disk or a floppy disk. At the time of this storage, identification information such as the document file name, version number and date is added and stored. Then, the document stored by using the identification information as a guide can be selectively read out, edited, and printed or stored again.

[0003]

By the way, in this type of document data processing apparatus, a document stored in a document file disk is read and edited, and the edited document is re-stored without changing the document file name. When doing so, that is, when updating, the version number as the identification information is unconditionally increased, and only the edited or final version document is saved.

Therefore, even if there is a case where the user wants to view the contents retroactively to the previous version of the document, he / she cannot see the contents.

An object of the present invention is to make it possible to view a document before updating even when a stored document is updated.

[0006]

The means of the present invention are as follows. When document data is stored, the stored document data is read and edited, and the edited document data is stored again, the original unedited document data is saved, and the original document data and the edited document data are saved. On the other hand, identification information for distinguishing each other is added and stored.

[0007]

The operation of the means of the present invention is as follows. After reading the document data stored in the document file disk etc. and editing it, when re-storing the edited document data,
While storing the original unedited document data, identification information for distinguishing the original and post-edited document data from each other, for example, a version number is added and stored. Therefore, it is possible to store the document data of different versions of the same document and to search and read the document before updating, that is, the document before editing by the above identification information, so that the desired document before updating can be viewed. become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 is a block diagram showing the configuration of a document data processing apparatus to which the document editing method of one embodiment of the present invention is applied. Reference numeral 10 in the figure is a CPU for controlling the whole. Reference numeral 12 is an input unit having character / numerical keys for inputting characters when creating or editing a document and various instruction keys for performing various processing instruction inputs. Reference numeral 14 is for storing document data being created or edited. It is a document memory. Reference numeral 16 is a display unit for displaying the document data stored in the document memory 14, and reference numeral 18 is a document file disk for storing the created or edited document data. An editing unit 20 creates document data according to an operation from the input unit 12 and stores the document data in the document memory 14, and edits the document data stored in the document memory 14, and 22 denotes a time and date. It is a clock to do.

The CPU 10 has a document file disk 18
The document data stored in the document memory 14 is read to the document memory 14, and the edited document data is written from the document memory 14 to the document file disk 18. When writing the document data to the document file disk 18, the clock 2
The current date and time is read from 2, and the date and time is written as one of the identification information in association with the document data.

Next, the operation in such a configuration will be described.

First, the operation of storing document data will be described with reference to the flowchart of FIG. That is, when the "save document" key (not shown) of the input unit 12 is operated, the CP
U10 determines whether the document data stored in the document memory 14 is a new document (step S1).
1) If the document is a new document, the input of the document name from the input unit 12 is accepted (step S12). Then, using this input document name as the directory name, the document file disk 18
A directory is created in step S13, the initial version number and the date measured by the clock 22 are added to the current document data in the document memory 14, and the document file disk 18
In the current directory (step S14).

On the other hand, if it is determined in step S11 that the document is not a new document, that is, an edited document, a version number designation screen 16A as shown in FIG. 3A is displayed on the display section 16 (step S15). . Here, when "Y" is selected (when the "Y" key and "return" key of the input unit 12 are operated), the latest version number under the current directory of the document file disk 18 is searched (step S16),
The version number (latest version number + 1) and the date counted by the clock 22 are added to the current document data in the document memory 14 and additionally stored in association with the current directory of the document file disk 18 (step S17). . In other words, a new version number is created and the document data of the old version number is saved with the same contents as before. As a result, it is stored in the document file disk 18 as shown in FIG. That is, one document is one
The structure corresponds to one directory, and the document data of each version is stored under that directory.

When "N" is selected in the state where the version number designation screen 16A is displayed (when the "N" key and the "return" key of the input unit 12 are operated), the document file is displayed. The latest version of the document data in the current directory on the disk 18 is updated with the contents of the edited document data in the document memory 14 (step S18). That is, the read document data is directly updated, and the previous contents are not saved.

Next, referring to the flowchart of FIG.
The process of reading the document data will be described. That is, the input unit 1
By operating a "read document" key (not shown)
0 reads all the document names from the document file disk 18 (step S21), and displays the list display screen 16B as shown in FIG. 3B on the display unit 16 (step S22). Then, after the cursor is moved to the designated document name by the cursor movement key operation (not shown) of the input unit 12 (step S23), when the "return" key (not shown) is operated, the document name designated by the cursor is changed. Document file disk 18 for the latest version of document data used as a directory
To the document memory 14 (step S24), and the contents of the document memory 14 are displayed on the display unit 16 (step S25).

On the other hand, when the cursor is moved to the designated document name on the list display screen 16B and the "read version number" key (not shown) of the input unit 12 is operated, the CPU 10 causes the CPU 10 to designate the document name designated by the cursor. Read all the version numbers with the directory as the directory from the document file disk 18 (step S2
6), the version number list display screen 16 as shown in FIG.
C is displayed on the display unit 16 (step S27). Then, after the cursor is moved to a designated version number by operating a cursor movement key (not shown) of the input unit 12 (step S2
8) When the "return" key (not shown) is operated, the document data corresponding to the version number designated by the cursor is read from the document file disk 18 into the document memory 14 (step S29), and the contents of the document memory 14 are read. It is displayed by the display unit 16 (step S25). That is, when it is desired to read out a specific version number of a document, when the cursor is moved to the document and the "version number read" key is pressed, a list of version numbers is displayed.

As described above, when the version number is designated, it is possible to automatically save the document of the version number before that, and at the time of storing it, the version of the document data having the same document name is stored. Since the identification information such as the number and the editing date and time is added, even if the document data having the same document name can be searched and read out by this identification information, the document data before the editing can be read and the desired pre-updated document data can be read. You will be able to see the document.

[0018]

According to the present invention, even when a stored document is updated, the document before the update can be viewed.

That is, since the means for storing the document of the previous version number is provided, it is possible to deal with the case where it is necessary to go back to the previous version number.
