Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document processing device such as a Japanese word processor.

Japanese word processors use a method that stores text data such as kanji, hiragana, numbers, and punctuation marks in separate memory, and graphic data such as ruled lines, blank spaces, and frames, and synthesizes them when displaying them. There is a method in which data and graphic data are mixedly stored in the same memory. However, in the method of storing the ruled lines and graphic data in separate memories, there is a problem that when ruled lines and characters overlap, the ruled lines are cut off unconditionally. In addition, in a method that stores text data and graphic data in the same memory, if you insert characters that cannot be inserted into the frame, you must either move the ruled line or cut the ruled line. ,
It is necessary to make decisions such as whether to insert characters past the ruled lines.

An object of the present invention is to enable text data to be input without worrying about graphic data even when the input position of text data reaches graphic data such as a ruled line.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a text memory in which text data and graphic data are mixed and stored. In this case, in the graphic data, a special code different from other ruled lines is assigned to the ruled lines ",", "," located at the four corners of the frame. As shown in FIG. 2, the document memory 1 has one character per byte.
A byte status storage unit is provided, and this status storage unit contains, for example, CRT blink,
Various statuses such as the upper left corner and the upper right corner are written, as well as statuses such as half bright.
A CPU is connected to the document memory 1,
Read data and write data are exchanged with the CPU. The document memory 1 is
The address is specified by the document memory address controller 2, which operates according to instructions from the CPU. Data read from the document memory 1 in accordance with the address designation of the address controller 2 is sent to the CPU and is also input to the ruled line discrimination circuit 3 and the distance counting circuit 4. The above ruled line discrimination circuit 3
is the data read from document memory 1,
The circuit that detects the ruled lines at the four corners described above sends the detected data to the ruled line information memory 5, which will be described in detail later, and stores it in a predetermined position, and when it detects the ruled line data at the upper left corner, it sends the detection signal to the document memory. Send to address controller 2. This address controller 2 is connected to a ruled line discrimination circuit 3, and when a ruled line data detection signal for the upper left corner is given from the ruled line discrimination circuit 3, the current document memory 2
address data is sent to the ruled line information memory 5 and stored in a predetermined position. Furthermore, when the ruled line discrimination circuit 3 detects ruled line data, it inputs a detection signal to the distance counting circuit 4. This distance counting circuit 4 is
The distance between the ruled lines, that is, the horizontal distance and the vertical distance, are counted based on the ruled line detection signal given from the ruled line discrimination circuit 3, and are outputted to the ruled line discrimination circuit 3 as reference data and stored in the ruled line information memory 5.
Of the data stored in the ruled line information memory 5, the distance data and the ruled line data at the upper left corner are read out to the ruled line discrimination circuit 3.

As shown in FIG. 3, the ruled line information memory 5 includes a flag storage area 11, a ruled line information storage area 12, a ruled line horizontal distance storage area 13, a ruled line vertical distance storage area 14, and a ruled line in the upper left corner. It consists of an address storage area 15. The ruled line information storage area 12 is configured to store the bits at the four corners of the ruled line, and when all the bits at the four corners become "1", the area is designated by the ruled line at the four corners. "1" is written in the corresponding flag storage area 11 as follows. The reading and writing of the ruled line information memory 5 is controlled by the CPU, and its stored contents can be read out to the CPU at will.

Next, the operation of the above embodiment will be explained. The text data and graphic data mixedly stored in the document memory 1 are read out to the CPU according to the address designation of the address controller 2 according to instructions from the CPU, and are displayed on the CRT display section 21 as shown in FIG. 4a.
Displayed in . FIG. 4a shows an example in which the characters "Tokyo" are written in the frame 22. Further, data read from the document memory 1 is sequentially sent to a ruled line discrimination circuit 3 and a distance counting circuit 4, where ruled line discrimination and distance counting between ruled lines are performed. The ruled line discrimination circuit 3 discriminates the contents stored in the status storage section from among the data read from the document memory 1, and detects ruled line data. The contents of document memory 1 are as follows:
Since the information is read out sequentially from the top line on the screen downward, the ruled line at the upper left corner of the frame 22 is first detected by the ruled line discrimination circuit 3. This ruled line discrimination circuit 3 is
When the ruled line at the upper left corner is detected, "1" is written into the corresponding bit of the ruled line information storage area 12 in the ruled line information memory 5, and a ruled line detection signal at the upper left corner is sent to the address controller 2. As a result, the address controller 2 outputs the address data for the document memory 1 at that time to the ruled line information memory 5,
It is stored in the address storage area 15. Furthermore, the ruled line discrimination circuit 3 outputs a ruled line detection signal at the upper left corner to the distance counting circuit 4. Thereby, the distance counting circuit 4 starts counting the distance between the ruled lines in accordance with reading data from the document memory 1. And after that,
When the ruled line data at the upper right corner is read out from the document memory 1, the ruled line discrimination circuit 3 detects it, writes "1" to the corresponding bit in the ruled line information storage area 12 in the ruled line information memory 5, and also writes "1" to the corresponding bit in the ruled line information storage area 12 in the ruled line information memory 5. Outputs the detection signal to. When the distance counting circuit 4 receives a ruled line detection signal for the upper right corner from the ruled line discrimination circuit 3, it sends the horizontal distance between ruled lines at that time to the ruled line information memory 5 and writes it in the storage area 13. Furthermore, when the ruled line data at the lower left corner is read out from the document memory 1, the ruled line discrimination circuit 3 detects it, writes "1" to the corresponding bit in the ruled line information storage area 12 in the ruled line information memory 5, and Counting circuit 4
Outputs the detection signal to. When the distance counting circuit 4 receives the lower left corner ruled line detection signal from the ruled line discrimination circuit 3, it sends the vertical distance between ruled lines at that time to the ruled line information memory 5 and writes it in the storage area 14. Then, when the ruled line data at the lower right corner is read out from the document memory 1, the ruled line discrimination circuit 3 detects it and writes "1" into the corresponding bit of the ruled line information storage area 12 in the ruled line information memory 5. When "1" is set in all the bits at the four corners of the ruled line in the ruled line information storage area 12 in this way, "1" is written into the corresponding flag storage area 11 by a command from the CPU.

Therefore, when the characters "Tokyo" are written in the frame 22 as shown in FIG. When the ruled line data is read following the character, the flag storage area 11 in the ruled line information memory 5 is referred to, and it is determined whether the ruled line indicates the boundary of the area specified by the ruled lines at the four corners. do. Then, the CPU uses the flag storage area 1 mentioned above.
If it is determined that the ruled line indicates the boundary line of the specified area from the contents of 1, the ruled line cannot be moved, and the character ``minato'' to be inserted is inserted in the frame 22 as shown in Figure 4b. Write on the line next to "Tokyo".

Furthermore, as shown in FIG. Move by character and write the inserted character ``Minato'' between ``Miyako'' and the ruled line 23. As described above, by looking at the contents of the flag storage area 11, it can be easily determined whether or not the ruled line can be moved, and the ruled line processing can be performed accordingly.

In the example of FIG. 4 above, the case where there is one frame 22 in one screen has been explained, but for example, as shown in FIG.
Even if there is 2, the process can be performed in the same way. In the case of FIG. 6, when searching the second line, the ruled line data at the upper left corner of the first frame 31 is first detected by the ruled line discrimination circuit 3, and the corresponding bit in the storage area 12 in the memory 5 is written as “ 1'' is written, and the address at that time is also written to the storage area 15. Then, the horizontal distance from the upper left corner ruled line to the upper right corner ruled line of the first frame 31 is determined by the distance counting circuit 4.
It is counted and written to the storage area 13. In this case, the horizontal distance is for 7 columns from the 3rd column to the 9th column, and since each column is in units of 2 bytes, the total
It will be 14 bytes. Next, when the fourth line is searched, the ruled line data at the upper left corner of the second frame 32 is detected, and the corresponding bit of the storage area 12 is set to "1" in an area different from that for the first frame 31 in the memory 5. ” is written, and the address at that time is also written into the address storage area 15. And the second
The distance in the horizontal direction from the ruled line at the upper left corner of the frame 32 to the ruled line at the upper right corner is counted by the distance counting circuit 4 and written into the storage area 13. The lateral distance in this case is
It consists of 5 columns from the 12th column to the 16th column, and is 10 bytes. Then, when the sixth row is searched, the ruled line at the lower left corner and the ruled line at the lower right corner of the second frame 32 are detected, and a horizontal distance of 10 bytes and a vertical distance of 6 bytes are counted. At this time, the ruled line discrimination circuit 3
is the horizontal distance counted by the distance counting circuit 4 and the first frame 31 and second frame 3 written in the memory 5.
2 is compared with the horizontal distance, and the lower left corner and lower right corner ruled line detection bits are set in the areas in the memory 5 for the matching frame 32, and the vertical distance of 6 bytes is written in the storage area 14. Furthermore, when searching the 8th line, the horizontal distance of 14 bytes and the vertical distance of 14 bytes with respect to the first frame 31 are counted in the same way, so the counted horizontal distance of 14 bytes is written to the memory 5. A match comparison is made with the horizontal distances for the first frame 31 and the second frame 32, and ruled line detection bits are set in the lower left corner and lower right corner in the area in the memory 5 for the matching frame 31, and the storage area Write the vertical distance of 14 bytes to 14. In this way, "1" is set in all the bits at the four corners of the frames 31 and 32 in the ruled line information storage area 12, and "1" is written in the corresponding flag storage area 11. Therefore, it can be easily determined from the flags whether the frames 31 and 32 indicate the boundary line of the designated area. In addition, although FIG. 6 shows the case where the horizontal distances of the frames 31 and 32 are different, if the horizontal distances are the same, it is determined that the horizontal distances are the same by comparing the lower ruled lines. At this time, the ruled line address in the upper left corner, which is the reference for the detected ruled line data, is calculated in the ruled line judgment circuit 3, and the ruled line address is compared with the ruled line address stored in the storage area 15 of the memory 5 to find out whether they match. The ruled line detection bits at the lower left corner and the lower right corner are set in the area in the memory 5 that is located, and the vertical distance is written. Through the above processing, ruled line information can be written in a predetermined area of the memory 5 even when the horizontal distances of the frames are the same.

According to the present invention, even when the input position of document data reaches graphic data such as a ruled line, the document data can be input without worrying about the graphic data. can reduce the burden of
