Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a text editing device in a Japanese word processor, and more particularly to a column setting method in a device that edits text in a multi-column format within one page.

Conventionally, for example, as shown in Figure 1, when you want to divide one page into the first, second, and third columns to create a character example as shown, a space ( SP) with the appropriate number of digits, print the first line in common in each column, then break the line and move to the second line.
U, eh, oh, SP, SP, SP, 1, 2,...D.
Since the system required input in the order of "E, new line, k, ki, ku, ...", the operator had to consider the arrangement of all columns when inputting characters, which had the disadvantage of greatly reducing work efficiency. .

The present invention solves the above-mentioned drawbacks and uses a word processor that automatically executes editing processing within a column while continuously inputting characters in each column, and displays only the input information in that column. Its purpose is to provide a text editing device.

Hereinafter, the present invention will be explained based on drawings of embodiments.

FIG. 2 shows an external perspective view of an embodiment of the present invention. In the figure, 1 is a CRT display device that displays input characters, 2 is a group of character keys for inputting characters, symbols, etc. that make up the text, 3 is a group of function keys, and 4 is a printer that prints the edited text. be.

As the function key group 3 mentioned above, the third
As shown in the figure, a column key 3A is used to set the multi-column mode, an execution key 3B is used to instruct execution of editing processing, a cancel key 3C is used to cancel mode settings, and a cursor position on the CRT display device is moved up and down. It is equipped with cursor movement keys 3D, 3E, 3F, and 3G for moving left and right. Other keys conventionally included in Japanese word processors are omitted.

Next, how to use the function key 3 will be specifically explained.

Before setting columns, set the paper size on which the text will be printed, for example A4, A5, etc. This setting determines the maximum number of characters in one line. Next, if it is necessary to set the number of lines, press the number of lines setting key 3J, input the desired number of lines using the numerical keys 2, and press the execution key 3B to complete the setting of the number of lines.

When configuring columns, first press column key 3.
When A is operated, a scale 5 indicating the line length of the previously set paper size is displayed on the CRT display device 1. Therefore, the cursor mark 6 is moved to the right end position of the first column using the cursor keys 3D to 3G. When the column setting key 3K is operated here, the number of characters in the first column is determined based on the cursor mark position and is stored in the memory. By repeating the same operation and specifying the right end position of the second column, the number of characters in the second column is determined. If the execution key 3B is operated here, the number of remaining characters in the third column is automatically determined from the line length and the right end position of the second column.

In multi-column mode, the first, second, and third columns each occupy one screen of the CRT display device 1, and these three columns are controlled continuously in the vertical direction, with individual input control for each column. will be held.

FIG. 4 shows a circuit block diagram of an embodiment of the present invention. This device includes a keyboard 40, a keyboard control circuit 41, a device control circuit 42, a cursor control circuit 43, a buffer memory 44, and a column control circuit 4.
5, text judgment circuit 46, text memory 47, address circuit 48, print control circuit 49, printer 4,
It is composed of a CRT control circuit 51 and a CRT display device 1.

The text memory 47 is an area for storing sentences for each column for column printing, that is, an area 471 for the first column and an area 47 for the second column.
Areas 473 for second and third columns are provided, and column control information 470 is written at the beginning of each column.

The column control circuit 45 has flags F ₁ 21 and F ₂ 2.
2, F ₃ 23, flag related to columns 24, flag related to number of rows setting 25, column character number counter
CC26 column line number counter CL27, column number counter CN28, pointer 29, buffer 3
0, a space code generation circuit 31, and a line feed code generation circuit 32 are built in. The buffer 30 includes columns BCC1, BCC2, and columns that store the maximum number of characters in each column.
BCC3, a column CCmax for storing the maximum number of characters in a line determined by the paper size, a column Buf for temporarily storing the code of the numeric key, and a column Bcl for storing the number of columns to be printed. The pointer 29 consists of a pointer P ₁ , a pointer P ₂ , and a pointer P ₃ that sequentially store the row start address of each column in order to address each column.

The print control circuit 49 includes a print buffer 491, and when a line feed code is introduced, prints a character corresponding to the character code of the stored sentence.

Next, the operation of the embodiment shown in FIG. 4 will be explained according to the flowchart shown in FIG.

FIG. 5A shows control related to function key operations such as column settings. First, the cursor is moved to a desired position using the cursor movement keys 3D to 3G, and the number of column characters in the first column is set using the column key 3A and execution key 3B.
This is done by counting the pulse signals generated by the cursor control circuit 43 by the column number counter CN28 and column character counter CC26.
This count value is registered in the text memory 47. Similarly, the second and third columns are converted into count values and registered in the text memory 47, 101, 10.
2. Next, when column key 3A is pressed, flag 24
are set 103, 104, and at the same time the column character counter CC26 is reset 115. At this time, the line number scale of the set paper size is displayed on the CRT screen. When the operator moves the cursor mark while looking at this scale, the column character counter CC26 counts the number of digits moved in the column direction as the cursor mark moves. When the cursor mark position is determined and the operator presses the column setting key 3K, the count value of the counter CC becomes buffer 3 because the flag _F1 is initially reset.
107, 108, 112, 116 are transferred to BCC1 of 0 and flag _F1 is set. Move the cursor to the end of the line in the second column again and press the column setting key. This time, flag _F1 has been set, so the buffer is set from the count value of counter CC26.
The subtraction CC-BCC1 of the contents of BCC1 is executed, and this is introduced into the buffer BCC2 and stored as the number of lines in the second column 128,109. In addition, the maximum number of lines memorized by the paper size setting
Subtraction of count value of counter CC26 from CCmax
CCmax-CC is executed and introduced into the buffer BCC3 and stored as the number of lines in the third column 110.
Note that in the case of two columns, if the cursor is moved to the end of the line, the value of BCC3 becomes "0" and the third column is not set. After these processes are completed, the flag _F1 is reset 111. character key 2
When is operated, the program proceeds to the character input process shown in FIG. 5B (113, 200). Further, when the execution key 3B is pressed, the program proceeds to the execution processing program shown in FIG. 5C (114, 300).

FIG. 5C shows control of execution of the function. Since the line setting flag 25 is set, the contents of the buffer Buf, which stores numerical values, are converted into binary signals by the key code signal and the buffer is stored.
301, 303, and 304, the line setting flag 25 is reset, and a function key input operation standby state is entered. When the column flag 24 is set, the number of lines in the buffer BCC1 is transferred to the character counter CC26, and the number of lines in the buffer Bel is transferred to the line counter CL27. Furthermore, the first column area 4 of the text memory 47
The first column code, the number of lines as the content of BCC1, and the number of lines as the content of Bcl are written to the column control information storage unit 470 at the beginning of 71, and the mode shifts to character input mode 302, 305, 30
6,307,308.

FIG. 5B shows control of the character input mode. In the initial state, the column flag F24 is in a reset state, while the row number flag 25 is set when the row number designation key is pressed.
The input numerical codes are transferred and stored in buffers 201, 202, 203, and 204. By repeating this operation, the sentences are sequentially stored in Buf, and the number of lines is stored. Note that if the column flag F24 and line number flag 25 remain in the reset state, each character code from the input key is input and processed as a normal sentence that is not divided into columns 201, 20.
2,205.

When column key 3A is pressed, column flag F2
4 is set. If a character key other than the line feed key is input here, the character code is sequentially written into the first column area 471 of the text memory 47 and at the same time the counter CC26 is counted down by 1.
07,208. This process is repeated 209 until the content of the counter CC becomes "2". counter cc
When the content of becomes “2”, line feed code generation circuit 3
2 generates a line feed code and writes it to the text memory. At the same time, counter CL27 for each new line
209, 210, 21 counts down by 1
1. Until the contents of counter CL becomes “0”,
Every time a line feed code occurs, the contents of buffer BCC1 are transferred to counter CC26, and similar character input operations are repeated 212, 213, 217.
Also, if the new line key is pressed in the middle of character input,
A line feed code is immediately generated and written to the text memory, and the input for this line ends.206,210,2
11. Note that the reason why line input is terminated when CC=2 is to create a space for two characters as a delimiter between each column. With the above operation, the first column area 471 of the text memory 47
The character code is stored according to the preset number of characters and lines. When the content of the line counter CL becomes "0" and the input of the first column is completed, the process moves to the input of the second column, and the buffer Bcl
The number of lines is transferred to the line number counter CL again21
2,218. In this case, column number counter CN
Since the content of is "0", the second column code and the content of BCC2, which is the number of lines in the second column, are written to the column control information storage section of the second column area 472 of the text memory 47 (219). 220.
Further, the column number counter CN28 is counted up and its contents are set to "1" 221. Furthermore,
The content of Batshua BBC2 is the column character number counter.
213, 214, 216 transferred to CC26.

After these settings are made, character input etc. is repeated in the same way as in the first column, and the text memory 4
201, 206, 207, 208, which are stored in the area 472 of the second column of No. 7 according to the input order.
209, 210, 211, 212, 213, 21
4,216. When the input of the second column is completed, the counters 212, 218, 219, 222
CN is “1” or buffer BCC3 is “0”
202, 203. Now, assuming that the column is divided into three, the content of BCC3 is not "0", so the third column of text memory 47 is
The third column code and the contents of the line number BCC3 of the third column are written into the column control information storage section of the column, the column number counter CN28 is counted up to set its contents to "2", and the contents of the buffer BCC3 are written. is column character number counter CC26
222, 22 to proceed to character input processing.
3,224,221,213,214,215.

Eventually, when the input processing for the third column is completed, the column flag 24 is reset, the counter CN is also reset, and the entire character input mode program is completed 225, 226.

FIG. 5D shows printing control. 401, 402, 403, 404 which sequentially address and read out the text memory 47 and perform normal printing processing. At this time, if a column code is detected in the read text code, a column flag 24 is set.
03,408. Furthermore, the column control information storage section of each column area of the text memory is sequentially read out, and the address value of the first character code of the first column is introduced into the pointer _P1 from the area of the first column.
Transfer the line count CC value to buffer BCC1. Similarly for other columns, pointers P ₂ , P ₃ ,
Transfer data to buffers BCC2 and BCC3.
Note that if there is no code in the third column, "0" is written in BCC3. Also, the number of rows in each column
The CL value is transferred 409 to counter CL27. Subsequently, the data is transferred to the address circuit 48 of the pointer _P1 , and the first position of the first column is addressed, and the data of BCC1 is transferred to the counter CC 410, 411.

Next, the character code is read from the text memory,
If it is not a line feed code, the read character code is transferred to the print buffer 491, and at the same time the contents of the column character counter CC are counted down by one 405, 406, 407. The character codes in one row of the first column are sequentially addressed and read, and the above operation is repeated. When a line feed code is detected, a space code is generated by the space code generation circuit 31, and this is sent to the print buffer 491.
At the same time, the counter CC26 is counted down by one. This operation is repeated 412, 413, 414 until CC=0. The reason why the space code is transferred to the print buffer in this way is to insert a space between columns during printing and continue with the next column.

When this operation is completed, one line of the first column is read out and sequentially stored in the print buffer. Subsequently, the first row of the second column following the first row of the first column is read out.

Since flags F ₂ and F ₃ are initially in the reset state, pointer P ₁ is incremented by one line and stored.
Furthermore, set F ₂ and copy the contents of BCC2 to the counter CC.
Further, pointer _P2 is transferred to address circuit 4.
415, 416, 417, 4 to control to select the address of the second column of the text memory.
18,419,420. Subsequently, the above operation is performed again, and the text in the same line in the second column following the first column is transferred to the print buffer 491. Since flag _F2 has already been set, pointer _P2 is incremented by one line and stored, and _F2 is reset (416).
421,422. Now, assuming that there is a third column, the flag _F3 is set, the contents of BCC3 are transferred to the counter CC, the pointer _P3 is transferred to the address circuit 48, and the third column is controlled to select an address. 423, 424, 425, 426. By repeating the previous operation again, the text in the same line in the first column, second column, and third column is transferred to the print buffer 491. When the transfer of the third column is completed and the line feed code is read,
Since flag F ₃ is set, pointer P ₃
is incremented by one line, the flag _F3 is reset, and the line counter CL27 is counted down by one.40
5,412,413,414,405,427,
428,429. Contents of line number counter CL CL = 0
If not, that is, if printing for the preset number of lines has not been completed, the contents of BCC1 are transferred to the counter CC again, the pointer _P1 is transferred to the address circuit 48, and the first, second, 430, 431, 432 for controlling the transfer of the same line in each third column to the print buffer; If CL=0,
The column flag 24 is reset and column printing is completed 433. In addition, if the column structure is divided into two, when reading of the text in the second column is completed,
It is determined that BCC3=0, 423, and then control is performed to read the first column.

According to the present invention, the operator can freely set columns while looking at the cursor on the screen, and the operator can automatically insert a line break within a column and move to the next column simply by inputting text. The work efficiency is extremely high because text editing such as the following is performed. Further, according to the present invention, when printing, the same line is continuously printed in common to each column, so printing efficiency is high.

Although horizontally written text has been described above, the present invention can be implemented in exactly the same way for vertically written texts.
