Also, when multiple processing devices that process the minimum editing unit are connected via a network or multi-terminal,
The means for managing whether or not editing is possible for each minimum editing unit reads into the editing memory and edits each unit such as a logical structure unit or area unit within a page based on the content of management information, or This allows multiple processing devices to simultaneously edit document data stored in one processing device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the features of the document editing device of the present invention. In the figure, one device is provided with a terminal A and a terminal B each having a display 33, a keyboard 42, and a coordinate input device (here, a mouse) 43. The document data 22 can be edited.

FIG. 2 is a diagram showing the structure of the document editing device in detail. In the figure, a keyboard 42 and a coordinate input device 43
is connected to an input controller 41, and the input controller 41 is connected to the system bus 7. Connected to the system bus 7 are an external storage device 2 in which document data is stored, a display controller 31, a CPU 1, and a network controller 6 for connecting to other devices via a network. Display controller 31 is connected to display 33 via display memory 32. Display controller 31, display memory 32, display 33,
Input controller 41, keyboard 42, and coordinate input device! ! A plurality of terminals 43 may be connected to the system bus 7 to form a plurality of terminals.

Further, the network controller 6 may not be connected and may not have a network configuration.

Memories 51 to 54 are connected to the CPUI.6 The memory 51 is connected to the terminals (display controller 31, display memory 32, display 33, input controller 41, keyboard 42) connected to the self-editing device.
and the coordinate input device 43 (hereinafter referred to as a terminal), and terminal management information of terminals connected to other editing devices connected via the network.

The memory 52 stores document common information required during document editing work. The memory 53 is a memory 54 that partially retrieves document data from the external storage device 2 for each minimum editing unit during document editing work and stores it only during the editing work.
stores an editing program that controls document editing.

To edit a document, first, the target document common information is read from the external storage device 2 to the memory 52, and the data of the minimum editing unit to be edited is read to the memory 53.The document editing program performs the above processing. After, keyboard 4
2 and the coordinate input device 43, and performs editing such as additions and changes to the document data on the memory 52 and 53. 6Finally, the document editing program terminates the editing operation according to the operator's instructions. do. At this time, the document data on the memories 52 and 53 is stored in a prescribed location in the external storage device 2.

FIG. 3 is a visual representation of the document data structure. Common document information includes the positions and data of pillars, the positions and data of non-pulls, vertical and horizontal distances (margins), and various initial data that are not visually visible. Moreover, the minimum editing unit data includes sentences, figures, images, etc. These interact with each other to display the document on the display.

Next, the data structure of the document data 22 will be explained in detail using FIGS. 4 to 7.

As shown in Figure 4, the document data includes data related to the entire document, that is, document management data 226 that manages the total number of pages, total number of chapters and sections, etc., format information (margins, pillars, non-pull, etc.), and various other data. Common information 2 for managing initial value data, etc.
21. Data for each of multiple minimum editing units (in this figure, 5 chapter section data 222, page data 223, area data 22
4), and management information 225 that manages the above-mentioned minimum editing unit.
Consisted of. Further, the details of the data structure of the management information 225 are as shown in FIG.

When editing a document, the common information is read out to the memory 52 and the data of the minimum editing unit to be edited is read out to the memory 53, as described above. At this time, as shown in FIG. 6, the reference flag and update flag in the management information 225 are checked, and the flag is read only when the flag is OFF, and when the flag is ON, it is controlled as being unusable. Note that even if each flag is ON (in use), there is no problem if it is the own terminal, so this is checked using the device ID and terminal ID, and the above control is performed (step 80-1.8O-2). .

If the corresponding minimum editing unit can be used after the above check, register its device ID and terminal ID, and set the reference flag and update flag to ON (step 8O-3); if it cannot be used, the minimum Find the edit unit and use it. Alternatively, wait for editing to finish on the other terminal before editing.

After passing through such exclusive control and obtaining permission to use, the document data such as the minimum editing unit is read into the memory 53 (step 8O-4), and the editing instructed by the input from the keyboard 42 and the coordinate input device 43 is performed. The operation is performed (
Step 8O-5).

In the editing operation, when a termination instruction (for example, an operation such as turning a page or editing another area) is given, the document data in the memory 53 is stored in the corresponding document in the external storage device 2 (step 8O-6). . Further, the device iID, terminal ID, and each flag in the management information 225 indicating that the own terminal is in use are reset (step 8O-7).

With the above operations, the same document can be edited simultaneously from multiple terminals, and since each minimum editing unit is exclusively controlled, editing can be performed without contradiction.

Next, an example in which the minimum editing units have a logical connection relationship will be described using FIGS. 7 and 8. In this example, a page is treated as the minimum editing unit, but there is no difference even if this is one chapter, section, or area.

First, the editing data is read from the external storage device 2,
Before that, it is checked whether there is any influence from the previous page using the correction delay flag (step 8l-1), and if there is an influence, the updated data from the previous page to the own page is transferred to the migration data pointer (Top).
, Qast), step 8l-2),
The correction delay flag is turned OFF (step 8l-3).

Thereafter, the updated page 0 is displayed and editing operations are performed as described above (step 8O-5).

When the editing operation is finished, check the connection relationship with the next page and whether or not it is necessary to request an update for the next page (step 8l).
-4) If necessary, change the migration data pointer (Top, Qast) of page 0 and turn on the correction delay flag in the management information of the next page (step 8l-5).

By performing the above processing, operations as shown in FIG. 8 can be performed. That is, FIG. 8 is a diagram showing that the character string at the end of the corresponding page flows to the next page by inserting the character string into the corresponding page. If the page is full of character strings and a character string is inserted, there will be a surplus of character strings at the end of the page corresponding to the number of inserted characters. Therefore, by the operation described above, this extra character string is inserted at the top of the next page. Repeat this until the next page is no longer affected. Note that if the next page is being used by another terminal, the above operation is temporarily interrupted and the data is reflected after waiting for the next page to finish being used.

FIG. 9 is similar to FIG. 8, but shows that not only character strings are transferred to the next page, but also areas within the page (graphics in this case) are transferred by similar processing. In the case of this diagram,
The character string "weather" and the area are connected, and by inserting the character string at the beginning of page 0, the character string "weather" moves to the next page, so the area also moves to the next page.

The basic operation of this control is the same as that explained with reference to FIG.

FIG. 10 is an example of terminal management information. Terminal management information manages the terminal name, device ID, and terminal ID that can access document data on that device. When accessing a document from any terminal, refer to this information and know the device ID and terminal ID. It has been made possible to do so.

〔Effect of the invention〕

According to the present invention, since the same document can be edited simultaneously from a plurality of terminals, it is possible to decentralize the document editing work.

Further, each minimum editing unit has a connection relationship with each other, and this connection relationship is automatically reflected during editing, so that the consistency of one document created by multiple operators can be maintained.

Furthermore, from the above, there is no need to perform troublesome document management, and it becomes possible to edit documents efficiently.
