FIG. 6 is a schematic flowchart for starting and stopping document information storage/reading operations according to the present invention. As shown in the figure, first, an operation instruction for a target rectangular area is input from the input device 14.17 (1791), and based on this, an input code is generated via each adapter 15, 15 and register 16.19i (1792). ). The document information storage/read execution control mechanism IO generates a corresponding input command (1091) and issues a request to each corresponding processing device (1092). As a result, each processing device starts execution (step 1093). These processes include rectangular area setting processing, rectangular area chain processing, reading processing of rectangular areas and their contents, processing of writing contents into rectangular areas, processing of deleting contents within rectangular areas, and methods of deleting rectangular areas. This will be explained in detail below.

First, the process of setting a rectangular area is performed as follows. This is done by writing and storing information representing a rectangular area whose upper left end point is a position expressed in virtual space coordinates in the document information storage device 11.

The method begins with the input device 17. Input device adapter 1
8. Based on the designation input by the input register 19,
Based on the display device screen coordinates input from the display device screen coordinate input adapter 15 and the display device screen coordinate input register, the virtual space coordinates are determined by the display device screen coordinate/virtual space address converter 52. . Based on this value,
The address in the document information storage device for storing the corresponding rectangular area information is determined by the rectangular area information storage address generator 61 and set in the document information storage address register 21. The virtual space coordinates are determined based on the flowchart shown in FIG.

The rectangular area information storage address can be set by hashing, synonym chain tracing, or the space in the rectangular area storage device 4 managed by list chain.
Obtain h as the address of the chain head information area. Figure 2 shows the rectangular area information storage format (A) and its content information (B).
)'f: Show. In the figure, 1101 is the virtual space coordinate (X-axis direction) of the upper left end point of the rectangular area, 1102 is the y-coordinate,
1103 is the size of the rectangular area in virtual space (X direction);
1104 is the same size in the y direction, 1105 is the address of the chain preceding rectangular area information area, 1106 is the same chain continuation area address, 11071. i rectangular area content information storage area address, 1108 is the same content MW, 1109 is the chain preceding rectangular area content information storage area at L/S,
1110 is the same chain continuation area address. When relying on hashing or synonym chain tracing, the rectangular area reading unit 35 checks whether a rectangular area whose upper left end point overlaps the obtained rectangular area information storage area address already exists, and requests document information reading. reception department 26,
Using the document information reading mechanism 24, the document information storage device 1
1, the information is read out to the rectangular area information buffer memory 21 and checked by the determiner 71. As a result of the determination, if there is a rectangular area whose upper left end points overlap, the rectangular area information storage area address and the address of another area are the same as those of the update request reception unit 82 of the document information storage address (2101 in FIG. 3) and the document By sequentially driving the information storage address updater 81, the rectangular area information storage address generation request receiving unit 62, and the rectangular area information storage address generator 61, the generator is generated and set in the document information storage address register 21. If there is no rectangular area where the upper left end points overlap, the process moves to the following.

Information on the lower right end point of the rectangular area to be set is input as a coordinate value on the display device screen in the same way as the upper left end point, and after being converted to virtual space coordinates, the information is sent to the rectangular area/rectangular area content information updating section 45
The rectangular area information buffer memory 31 is updated based on this content. Thereafter, the document information storage device 11 corresponding to the value of the document information storage address register 21
The storage area within is updated by the document information writing mechanism 23. When the completion of writing is reported from the document information writing/reading completion accepting unit 27 to the document information storage/reading execution control mechanism, the display graphic conversion unit 28 is driven to write data into the rectangular area information buffer memory 31. Data representing the outline of the rectangular area is written to the display graphical conversion output data buffer 12 and displayed on the display device 14.

(((In order to be able to fill in a text string into a rectangular area of a number, define an area chain between the set rectangular areas. After the rectangular area setting operation or the read operation described later, the chain When a request is input, the rectangular area information buffer memory 31 is saved and the rectangular area information corresponding to the chained rectangle is read out to the rectangular area information buffer memory 32 by a read operation described later, while keeping fc. The rectangular area/rectangular area content information updating unit 45 writes information (3105 and 3106 in FIG. 4) representing the chain relationship of areas between the two rectangular area information buffer memories 31 and 32.

This writing is performed by reading the address in the document information storage device of the preceding or continuation rectangular area of each rectangular area from the document information storage address register 21.22, and writing 1 into the rectangular area information buffer memory 32.31. Let's do it. After this, the rectangular area information buffer memory, 31.3
The document information storage device 11 is updated according to the contents of step 2.

Delete chains between rectangular areas as follows.
Ru. The chained rectangular area information is called into the rectangular area information buffer memory 31 and 32, and the continuous rectangular area information 3106 in the rectangular area buffer 31, the preceding rectangular area information 3105e in the rectangular area buffer 32,
The rectangular area/rectangular area content information updating unit 45 marks the area as FF to indicate that it is non-continuous, and then updates the document information storage device 11 based on the contents of the rectangular area information buffer memo IJ31, 32. FIG. 4 shows the structure of the contents of the rectangular area information buffer memo 1J41, 42.

In the figure, 3101 and 3102 are the virtual space coordinates of the upper left end point of the rectangular area to be read and written in the X-axis direction and the y-axis direction, respectively, and 3103 and 3104 are the size of the rectangular area in the X direction and the y direction, respectively.

3105 is the preceding rectangular area area address of the chain to be read and written, 3106 is the same chain continuation area address, 3107 is the content information area address of the rectangular area to be read and written, 4108 is the same content information, 41
09 is the read/write target chain preceding rectangular area content information storage area address 411O is the same chain continuation area address.

The reading process for a rectangular area is as follows.

The information representing the entire rectangular area whose upper left end point is the position indicated by the specified virtual space address register 51 is read from the document information storage device 11 to the rectangular area information buffer memory 31, and then the rectangular area information buffer - Based on the read/write target rectangular area content information storage area address 3107 in the memory 31, the rectangular area content information 1108 to be placed in the read rectangular area,
The rectangular area content information 41o8 for glare writing is read out in the rectangular area content information buffer memory 41 and displayed on the display device 14. When the rectangular area content information 4108 remains in the document information storage device 11 in addition to what has been read out to the rectangular area content information buffer memory 41, the read/write target chain continuation rectangular area stores the remaining information. Content information storage area address 411o
The value is stored in the document information storage address register 21, and then the information in the remaining rectangular area is read out to the rectangular area content information buffer memory 41 and displayed on the screen of the content display device 14. While the rest of the content information arranged in the rectangular area is being sequentially read out and displayed, the display iconography conversion unit 28 detects that information that overflows from the rectangular area remains. At this time, if the read/write target chain continuation rectangular area information storage area address 3106, which is the content of the rectangular area information buffer memory 31, is set, Iii is set in the document information storage address register 21, and the rectangular area Information x, 7a, to memory 31, from document information storage device 11,
Continuing rectangular area information is read out, and then the overflowed content information is placed in the rectangular area by the display graphic conversion unit 28 and displayed on the screen of the display device 14. If there are multiple overlapping rectangular areas whose upper left end is the position represented by the basket, when a read request for the overlapping rectangular area is input, the rectangular area information is read into the rectangular area information buffer memory 31. The rectangular area information storage address of a rectangular area other than the rectangular area displayed on the screen of the display device 14 is updated by the document information storage address updater 81 and the rectangular area information storage address generator 61. The corresponding rectangular area information is read into the rectangular area information buffer memory 31 and displayed on the screen of the display device 14.

The processing when a request is made to write content into a rectangular area is as follows. When a chain is set between rectangular areas, information representing the first rectangular area of the chain is stored, and when no chain is set, information representing the specified rectangular area is stored in the rectangular area information buffer memory. 31, and in response to a request for filling in the contents of a rectangular area, the address value of an unused rectangular area content information storage area in the document information storage device 11 is read out by the rectangular area content information storage address generator 91. , writes the value to the read/write target rectangular area content information storage area address 3107 of the rectangular area information buffer memory 31, and reserves an area for one floor in the document information storage device 11. Next, the input information is written into the rectangular area content information buffer memory 41 and displayed on the screen of the display device 14. When the rectangular area content information buffer memory 41 overflows, the address of the area in the document information storage device 11 for entering new content is set in the document information storage address register 22 to secure the area, and the address is written to the read/write target chain continuation area content storage area address 4110 of the rectangular area content information buffer memory 41. At the same time, the value of the document information storage address register 21 is transferred to the rectangular area content information buffer memory 42.
Based on the contents of the rectangular area content information buffer memory 41, the sentence '4. All corresponding areas in the information storage device 11 are updated. After this, the contents of the rectangular area content information buffer memory 42 are
The information is stored in the rectangular area content information buffer memory 41, and the value of the document information storage address register 22 is written into the document information storage address register 21. Thereafter, the overflowing information sound is written into the rectangular area content information buffer memory 41. Through the above processing, the document information storage device 110 continues to be updated, and finally
When the flow no longer occurs, a mark indicating no continuation is written in the read/write target chain continuation rectangular area content information storage area address 4110 of the rectangular area content information buffer memory 41, and statement 1: written to the information storage device 11. Every time the read/write target rectangular area content information 4108 in the rectangular area content information buffer memory 41 is updated, the display icon conversion unit 28 converts the data into the display device 14.
Display on the screen. It is known from the rectangular area information Q9 chain continuation rectangular area information storage area address 3106 in the buffer memory 31 that the rectangular areas are chained, and the rectangular area is located outside the rectangular area. When the information is generated, the information representing the entire continuous rectangular area is read into the rectangular area information buffer memory 32 and written and displayed.

After reading and displaying a rectangular area or a set of chained rectangular areas and their contents, if deletion of the contents of the rectangular area is specified, first the rectangular area information buffer memory 3,
Whether or not the rectangular area preceding the rectangular area read out in No. 1 is connected in a chain is determined from the content information storage area address of the chain preceding rectangular area to be read and written. Next, the information of the rectangular area at the head of the chain is read into the rectangular area information buffer memory 1,131.

After that 1. The value of the read/write target rectangular area content information storage area address 3107 in the rectangular area information buffer memory 31 is stored in the document information storage address register 21.
Then, the document information storage device 11 reads the information in the corresponding rectangular area content 1 to the rectangular area content information buffer memory 41.Then, among the buffer contents, the chain continuation rectangular area content information to be read and written is read out. The storage area address 4110i is temporarily set to the document information storage address register 22 for evacuation.Furthermore, a code indicating unused is written to the rectangular area 11h content information buffer memory 41, and the document information storage address 1 is set to the document information storage address register 22 for evacuation.
