Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a document creation device such as a word processor, and particularly to a table creation device suitable for creating or manipulating a table constituted by ruled lines.

[Background of the invention]

Each square in the table (hereinafter referred to as the table unless otherwise specified)
As a method of associating it with ruled lines when inputting VC data, for example, the K
, there are methods that change the display position of data to be input at any time based on position information of already drawn ruled lines.

In this method, data is entered assuming the width between the vertical ruled lines in the already drawn table as a given value, so K is easy, but
It was necessary to decide in advance the number of ruled lines, the width between ruled lines, etc.

[Purpose of the invention]

The purpose of the present invention is that when a user of office automation equipment such as a word processor or a personal computer creates a table, he or she does not have to be conscious of the size of each square in the table (he or she can input a large number of characters, while at the same time being able to To provide a table creation device which automatically corrects the position of ruled lines and which can realize essential table operations with one-touch key operations.

[Summary of the invention]

In order to achieve the above object, in the present invention, in addition to conventional character keys, function keys for creating a table and function keys for operating a cursor are assigned to an input device, and furthermore, keys input from this input device are assigned. We have set up a key analysis section that analyzes the contents one by one. The function keys for creating a table include line breaks, adding rows, inserting blocks, 8 people in columns, deleting blocks, and Deleting columns, dividing the flock into upper and lower parts,
There are keys for left and right division, etc., and the function keys for operating the cursor include a character cursor key that moves the cursor character by character, and a cell cursor key that moves the cell cursor that indicates the cell to be operated. Here, a cell refers to a partial area corresponding to one row in a block in the case of a horizontally written block, and a partial area corresponding to one column in the block in the case of a vertically written block.

By operating these keys, it is possible to add, delete, insert, divide into two rows and columns of a table, and move the cursor with a single key operation.

[Embodiments of the invention]

An embodiment of the present invention will be described below. FIG. 1 is a block diagram showing the functional configuration of an embodiment of the present invention.

In FIG. 1, a processing device 101 is, for example, a microprocessor, which reads and executes a program stored in a program memory 102, and controls each functional block and data transfer via a path line 105. The key input device 105 includes alphabetic characters, numbers,
In addition to character keys for hiragana, katakana, and symbols, it is equipped with function keys that have specific roles.

Further, the kana-kanji conversion device 119 has a kana-kanji conversion function for Japanese input.

Character codes corresponding to the character keys pressed by the key input device 1050 or kanji codes by the kana-kanji conversion device 119 are stored in the internal buffer memory 116, and at the same time, the character display control circuit 111 outputs them to the character cursor register 108 on the display device 112. Displays the character pattern at the indicated position and advances the contents of the character cursor register one character.

On the other hand, character display position information is transmitted to the ruled line display control circuit 115. The ruled line display control circuit 113 determines whether the character display position exceeds the already drawn ruled line, and if the character display position exceeds the already drawn ruled line, the ruled line display position is set to the right of the character display position and the ruled line is redisplayed.

Furthermore, when a character cursor key of the character cursor moving device 106 is pressed, the key analysis circuit 104 determines the direction and amount of movement of the cursor, and updates the value of the character cursor register 10B according to the direction and amount of movement. do. The cursor display control circuit 114 refers to this and displays the moved character cursor on the display device 112.

When a cell cursor key of the cell cursor moving device 107 is pressed, the key analysis circuit 104 determines the direction and amount of movement of the cell cursor, and updates the value of the cell cursor register 109 according to the direction and amount of movement. . The cursor display control circuit 114 refers to this and displays the moved cell cursor on the display device 112.

When a function key is pressed from the key input device 105, the key analysis circuit 104 determines the meaning of the function, such as row deletion, column deletion, row insertion, column insertion, row addition, column addition, etc. The matrix control circuit 110 controls an internal buffer number register 115 that indicates the number of the internal buffer that is currently being operated, and this internal buffer 7 according to the instructed function.
internal buffer address 1 indicating the address of the text in
17 is updated, and the ruled line memory 118 is updated accordingly. Furthermore, the character cursor register 108 and cell cursor register 109 are updated.

Matrix control times jli! i 110 informs the character display control circuit 111, ruled line display control circuit 115, and cursor display control circuit 114 Vc that these registers, addresses, memories, etc. have been updated, and each of these circuits updates the character, address, memory, etc.
The ruled lines are displayed on the cursor display device 112.

FIG. 2 shows the flow of processing in comparison with the conventional method. FIG. 2 (α) shows the conventional method, and FIG. 2 (b) shows the method of the present invention.

In the conventional method, since there is no corresponding processing module in the matrix control circuit 110 in FIG. 1, simultaneous control of text data making up a table, that is, the internal buffer memory 116 in FIG. 1, and ruled line data, that is, the ruled line memory 118 is not possible. It was difficult. Therefore, the processing flow is shown in Figure 2 (α) VC
As shown, there are two main operation steps: first, the internal buffer is edited, and then the operator manipulates the ruled lines while viewing the displayed results.

In the present invention, since the matrix control circuit 110 always updates the internal buffer memory 116 and the ruled line memory 118 in a continuous manner, as shown in FIG. Both sides of the ruled line are edited and updated and displayed, so the operator does not need to be aware of the results of each.

FIG. 3 (α) shows the character input operation and screen display. A table 501 is a table in which characters are being input, a cell 502 is a cell where characters are stored, a character cursor 503 is a character cursor that indicates the position where the next input character will be displayed, and a ruled line 504 is a table between blocks. These are vertical ruled lines that indicate boundaries. Enter "Hitachi Manufacturing" from the key input device 105 shown in FIG.

and is displayed. If you enter "location" here.

do. The key analysis circuit 104 determines that the input key is a winter character, and stores the character code corresponding to the input character in the internal buffer register 15 and the internal buffer address 11.
Store it in the position indicated by 7 on the internal buffer. Next, character cursor register 08 and internal buffer address 1
Advance 17 by one character. Based on this information, one character is input from the character display control circuit 111, the ruled line display control circuit 115, and the cursor display control circuit 114Vc, as shown in FIG. The new table you moved is redisplayed. As more characters are input, the ruled lines move in the same way as in the processes described above.

FIG. 4 shows an operation for moving a cell cursor indicating a cell to be operated and a screen display. Table 400 is the table to be operated, and the cell cursor is at position 1 of 401.

Suppose that the user presses the upward movement key on the cell cursor moving device 107 of FIG. 1, tf. key, the analysis circuit 104 moves the cell cursor upward.

The cell cursor register, which determines that the instructions are.

The contents of the register 109 are changed to the address of the first cell of the block one block above, and the contents of the character cursor register 08 are changed to the address of the first character position of the same cell.

Based on this information, a cell cursor is displayed at position 402 by a single character display control circuit, a ruled line display control circuit, and a cursor display control circuit. 405, 404, 405 by similar processing for the downward, leftward, and rightward directions.
The cell cursor moves to the position.

Figure 5 shows the pron as the cell cursor moves.

This is an example of adding more. Table 500 is the table to be operated.

Yes, the cell cursor is at position 501. Here, it is assumed that the operator gives a downward instruction. In Figure 4.

As a result of processing similar to that described in , the cell cursor moves to the position 502. Furthermore, the ruled line display control circuit 114 detects that the cell cursor is outside the already drawn ruled line, and draws a horizontal ruled line under the cell cursor to supplement the vertical ruled line.

FIG. 6 is an example of line feed processing during character input to a certain block. In table 600, the words "Hitachi" are entered in position 601 of the existing IC (Fig. 6 (α)).
, Now suppose that you specify a key that means newline. When the key analysis circuit W8104 determines a return line feed, a line feed symbol is stored in the position indicated by the internal buffer address on the internal buffer, and the internal buffer address is advanced by one character.

Next, the character cursor register and cell cursor register are advanced by one line. At this time, if there is no line in the block to advance these cursors, one line is added to the internal buffer memory. Furthermore, set the length of the vertical ruled line to 1
The ruled line memory is updated so as to lengthen the block by one line and lower the starting position of the block below the block in the horizontal ruled line one line at a time.

FIG. 7 shows an example in which the column delete key is pressed as one of the function keys. In table 700, the cell cursor is at position 701. When a column deletion key is pressed by the key input device 105 of FIG. 1, the key analysis circuit 104 determines that a key for deleting a column has been designated. Next, all internal buffer addresses indicated by the cell cursor register 1090 column address are changed to the next column.

As a result, the cell cursor moved to position 702 in Table 7
05 is redisplayed.

〔Effect of the invention〕

According to the present invention, when creating a table and entering characters,
It is possible to input one character at a time without being aware of the size of the table in advance, and to automatically create a table accordingly. In addition, when adding, inserting, deleting, etc. to a created table, you can perform the process by simply pressing the key assigned to that role with a single touch, making table creation, input, and editing extremely easy. becomes easier.
