Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a simple tabulation device suitable for use in information equipment having a tabulation function, such as a word processor or a personal computer.

[Summary of the Invention] The present invention provides an information device having a tabulation function, such as a word processor or a personal computer, when a ruled line cursor key (up, down, left, and right four keys) is operated in a ruled line addition or deletion mode. , check the ruled lines that are perpendicular to the ruled line direction (vertical direction if it is top or bottom, horizontal direction if left or right) and that constitute the outer frame of the table, and use the add and delete mode within the range of both orthogonal ends. This allows you to add or delete each ruled line. However, if there are no orthogonal ruled lines, the edge of the screen becomes one edge. Further, when addition or deletion is performed, the cursor automatically moves to the end point according to the direction indicated by the cursor key.

[Prior Art] Conventionally, in information devices having tabulation functions such as word processors and personal computers, the following methods have been used to draw or delete ruled lines for tabulation. there were. That is, ■ Pseudo-graphic characters (Ro 9th, Ta.

A method of displaying ruled lines as a set of characters using keys such as 田, Tomoe, [E, 田, 田, 田9日, 田, etc.), and then deleting the ruled lines by filling the spaces with space characters.

■ By moving the cursor while holding down the "Rules" key,
Or, after pressing the "rules mode" key, draw a rule by moving the cursor. Then, the ruled lines are deleted by moving the cursor while pressing the ``ruled line deletion'' key, or by moving the cursor after pressing the ``ruled line deletion mode'' key.

■ A method for creating or deleting ruled lines by specifying the two points (point A and point B) on the ruled line as the designated starting point and ending point, respectively. However, there are two ways of specifying in this method:

That is, a) When specifying both ends of a straight line b) When specifying diagonal lines such as the upper left and lower right ends of each frame (box) [Problems to be solved by the invention However, the above , (2) have the problem that long line segments must be created and deleted one character at a time by key operations, which is time consuming.

Furthermore, when the ruled lines intersect, if the ruled line including the intersecting lines is deleted, the necessary part also disappears, and the system has to be rewritten again by inputting another character or manually using the keys.

Furthermore, in the method (2) above, since the space key is a display key, the cursor advances to the right each time this key is pressed. Therefore, when erasing a vertical line, it is necessary to repeatedly operate the space key, execution key, cursor key, etc., which has the disadvantage that erasing the ruled line is extremely troublesome.

Furthermore, in the method (2) above, the operability was not good because the terminal had to be specified for both the start point and the end point. Furthermore, there is a restriction that the start and end points must be on the same straight line or on a diagonal line, which makes it difficult to operate, and when working with complex ruled lines, it is difficult to specify diagonals. had. Furthermore, it is necessary to specify two points, and when specifying a large number of minimum sections, there is also a drawback that efficiency is poor.

The present invention has been made in view of the above points, and is a simple and easy-to-understand method for adding and deleting ruled lines to tables that have already been created using simple key operations. The purpose is to provide a table device.

[Means for Solving the Problems] FIG. 1 is a block diagram showing the configuration of the present invention. In the figure, 1 is a key input unit having a mode key for requesting a ruled line addition or deletion mode, and a cursor key for specifying the addition or deletion direction of the ruled line, and 2 is a key input unit for the above-mentioned key input. Section 1 is an intersection search means for searching for each intersection with two inputted ruled lines that are orthogonal to the direction indicated by the cursor key and that constitutes the outer frame of the table; the intersection,
An end point storage means 4 stores the start and end points of adding or deleting a ruled line, and 4 is used to add a ruled line between the start and end points stored in the end point storage means 3 or to add a ruled line between the start and end points stored in the end point storage means 3, depending on the mode. This table processing means performs a process of deleting ruled lines.

[Operation] To explain the operation of the present invention, when adding or deleting ruled lines to a table created in advance, the key input section 1
Set the mode by operating the "Add" or "Delete" key, and specify the direction using the cursor keys. Then, the intersection search means 2 searches for each intersection with two ruled lines that are orthogonal to the designated direction and that constitute the outer frame of the table. Then, the end point storage means 3 stores each intersection searched by the intersection search means 2 as the start and end points of adding or deleting a ruled line. The table processing means 4 adds a ruled line between the start point and the end point stored in the end point storage means 3, or deletes the ruled line between the start point and end point, depending on the mode. . Therefore, it is possible to add and delete ruled lines easily and visually with simple key operations.

[Embodiment] (1) Configuration An embodiment of the present invention will be described below with reference to the drawings. Second
The figure is a block diagram showing its actual configuration. In the figure, 10 indicates mode setting keys ("Add" key 101. f Delete" key 102) and up/down/left/right cursor keys ("↑" key 103. J primary key 04゜ “←” key 105.r→”

(The operation of the simple tabulation device configured to perform two or more operations will be explained with reference to the flowcharts of FIGS. 3 to 6.
The figure is a flowchart for explaining the overall operation of ruled line processing. First, key human power is accepted (step 5301),
If a key has been input, the key is determined (step 8302).

If the input key is the ``r add'' key 101, the add mode is set in the mode register 20 (step 8).
303), the process returns to step 5301 and waits for key personnel. Similarly, the input key is the "delete" key 102
If so, I set the deletion mode in the mode register 20 (step 5304>, return to step 5301, and wait for key input).

If the input key is cursor key 103-106,
The direction of the cursor is set in the cursor direction register 22 (step 8305). Here, if it is not in the add or delete mode (step 8306), after setting the ruled line code in the specified direction (step 5307), the cursor is shifted in the specified direction (step 3308), and the process returns to step 5301. If it is in the addition or deletion mode (step 5306), after performing end point search processing 1 drawing processing and cursor movement processing (steps $309 to 5311), the process returns to step 5301 described above.

FIG. 4 is a flowchart for explaining the end point search process (step 8309). However, the ruled line is treated as a set of ruled line characters, and the ruled line characters are 1.2, 4.
Code with a weight of 8. Therefore, 11(II
The border characters and their codes are as follows.

Ta: 39th: 12. Ta:15. Tomoe: 9. Tomoe=5゜Ro:1
01ro: 6. Tania, Ta: 11. Tomoe: 13° Ta: 14 In other words, in the end point search process, first, the cursor key input in step 5301 is
, 105 (step 5401).

If it is the up or left cursor key 103 or 105, then it is determined whether it is the up cursor key 103 (step 8402). If it is the upper cursor key 103, the code one line above is read (step 5403), and it is determined whether the read code is a ruled line code with a weight of 4.8 (step 3404). If it is not a ruled line code with a weight of 4.8, proceed to step S403 above.
If the ruled line code has a weight of 4 or 8,
It is roughly determined whether there is a field or road code in the left and right direction (step 3405). That is, it is determined whether the ruled line constitutes the outer frame of the table. If it is not a ruled line that constitutes the outer frame of the table, step 5403
Returning to step 8406, if the line is a ruled line constituting the outer frame of the table, the read position is set in the starting point register 26 as the starting point (step 8406). Thereafter, the code one line below is read (step 3407), and if the read ruled line code is not a ruled line code with a weight of 4.8 (step 3408), the process is repeated from step 5407. If the ruled line code has a weight of 4 or 8 (step 5408), it is determined whether there is a tomoe or mortar code in the left and right direction (step $409). If there is no position, the process returns to step 5407, and if there is, that position is set as the end point in the end point register 28 (step 5410).

Furthermore, if it is determined in step 5402 that the input cursor key is not the up cursor key 103,
The code on the left of one line is read (step 8411), and it is determined whether the read code is a ruled line code with a weight of 1.2 (step 5412). 1.2
If it is not a ruled line code with a weight of
Repeating from step 11, if the ruled line code has a weight of 1.2, it is further determined whether there is a mouth or mortar code in the vertical direction (step 5413>. That is, the ruled line constitutes the outer frame of the table. Determine whether the border is the one you want.

If it is not a ruled line that constitutes the outer frame of the table, follow step $4 above.
Returning to step 11, if the ruled line constitutes the outer frame of the table, the read position is set in the starting point register 26 as the starting point (step 5414).

After that, read the code one line to the right at step 5415.
), if the read ruled line code is not a ruled line code with a weight of 1 or 2 (step 841G), the process is repeated from step 5415. If the ruled line code has a weight of 1.2 (step 3416), it is determined whether there is a day or snake code above or below it (step 3417).

If there is not, the process returns to step 5415, and if there is, that position is set as the end point in the end point register 28 (step 5410).

Also, if it is determined in step 5401 that the cursor keys are not up or down cursor keys 103, 105, then down.

End point search processing is performed in accordance with the right cursor keys 104 and 106. These are the above-mentioned left cursor key 103
, 105, so no particular explanation will be given.

Thereafter, the process proceeds to the drawing process (step 8310). This drawing process will be explained below with reference to the flowchart shown in FIG. First, in the same way as the end point search process described above, it is determined whether the cursor key input in step 5301 is the up and down cursor keys 103 and 1 (14) (step 3501). If it is the up and down cursor keys 103 and 104, Weight 2 is set to the code of the start point searched in the above end point search process (step 5502).

However, in this case, it is in the addition mode, and in the deletion mode, weight 2 is turned off for the code at the starting point.

Thereafter, it is determined whether one line below is the end point (step 3503). If it is not the end point, weights 1 and 2 are turned on (turned off in deletion mode) for the code one line below (step 5504), and the process returns to step 5503. If it is the end point, weight 1 is turned on (or off in deletion mode) for the code of that end point (step 3505).

Also, in step 5501 above, the up/down cursor key 10
If it is determined that the code is not 3 or 104, a weight of 8 is turned on (or off in the deletion mode) for the code of the searched starting point (step 8506). After that, it is determined whether the first line to the right is the end point (step 5501), and if it is not the end point, a weight of 4.8 is turned on (off in delete mode) for the code on the right of the first line (step 8508), and the above Return to step 5507.

If it is the end point, weight 4 is turned on (turned off in deletion mode) for the code of that end point (step 5509).

After adding and deleting ruled lines in this manner, cursor movement processing (step 8311) is performed. This cursor movement process will be explained below with reference to the flowchart of FIG. First, if the cursor key input in step 5301 is
Determine whether it is 03 to 106 (step 5601)
. The input cursor key is up or left cursor key 10
If it is 37105, the above starting point is set as the cursor position in the cursor position register 18 (step 86
02).

If the input cursor key is the down or right cursor key 104 or 106, the end point is set as the cursor position in the cursor position register 18 (step 8603). Then, a cursor is displayed at the set position (step 5604).

In this way, when the ruled line cursor keys (up, down, left, right, 4 keys) are operated in the ruled line addition or deletion mode, a ruled line that is perpendicular to the ruled line direction (up/down direction for up or down, left/right direction for left or right) is operated. In addition, it is also checked whether the ruled line constitutes the outer frame of the table, and if it is a ruled line that constitutes the outer frame, each of the ruled lines is Add or delete ruled lines, and the cursor automatically moves to the end point according to the cursor direction.

FIGS. 8(a) to 8(C) show examples of the display. That is, when a table as shown in FIG. 2A has already been created and the cursor 42 is at the position shown in the figure, for example, the "Add" key 101 and then the up cursor "
When the ↑" key 103 is operated, a ruled line is added and the cursor 42 is moved as shown in FIG. here,
For example, when the "delete" key 102 and the down cursor "↓" key 104 are operated, the ruled line is deleted and the cursor 42 is moved as shown in FIG.

In this way, it is possible to easily and visually understand the addition or deletion of ruled lines to or from an already created table by simple key operations.

Although not particularly described in the above embodiment, if there is no ruled line orthogonal to the specified direction, the screen edge may be set as one edge.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to provide a simple tabulation device that can easily and visually understand the process of adding and deleting ruled lines through simple key operations. can.
