Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device having a function of efficiently displaying or erasing ruled lines in document information.

[Prior Art] Conventionally, in the ruled line operation function of word processors, etc., the ruled line range is specified and drawn in front and behind, respectively, or the cursor is moved while looking at the display screen of a display device such as a CRT. The operation was to pull the B Pit.

[Problems to be Solved by the Invention] Therefore, when an operator performs this type of ruled line operation, there is a drawback that it is necessary to perform the above-mentioned complicated operations.

[Means for Solving the Problem] As a means for solving this problem, for example, the document processing apparatus of the embodiment shown in FIG. a recognition means 3 which recognizes the range of the outermost frame in a frame surrounded by the ruled lines in document information in the document memory 1 upon receiving an instruction from the processing instruction means 2; , a ruled line processing means 4 that executes ruled line processing within the outermost frame in response to the recognition result of the recognition means 3, and a display means 7 that displays document information in the document memory 1 processed by the ruled line processing means 4. The ruled line processing means 4 further recognizes whether or not a ruled line is drawn at the cursor position column, and when a ruled line is drawn at the cursor position, erases the ruled line at the cursor position column within the outermost ruled line frame. and a ruled line display means that draws a vertical ruled line within the outermost frame of the column at the cursor position when no ruled line is drawn at the cursor position.

[Function] In the configuration shown in FIG. 1, when the cursor is located within a frame surrounded by ruled lines due to an instruction input by the processing instruction means 2 such as pressing a ruled line operation key manually, the cursor is located within a frame surrounded by ruled lines. The range of the outermost frame is automatically determined, and the following processing is executed for the cursor digit within that frame.

That is, if no ruled line has been drawn at the cursor digit, a ruled line is drawn, and if a ruled line has already been drawn at the cursor digit, the ruled line is erased.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block configuration diagram of an embodiment according to the present invention. In the figure, 10 is a keyboard, and ruled line operation keys 1 are used to instruct a ruled line operation to a frame surrounded by ruled lines.
1 and other keys necessary for text processing.

Reference numeral 12 denotes, for example, a microprocessor C20 which manages the overall control of this embodiment, and performs various controls necessary for document processing, such as processing procedures stored in the ROM 13, which will be described later.

Reference numeral 13 denotes a read-only memory (R
OM).

14 is a writable memory (RAM), which includes a document memory 15, a cursor register 16, and a leading display register 17.
, and other memory areas 18 necessary for character processing.

The document memory 15 stores document information based on character codes and various information related to the stored document information.

The cursor register 16 stores the position information of the cursor displayed on the display 20, and the head display register 17 stores the position of the head character of the displayed characters.

Further, 20 is a display device on which characters and a cursor are displayed;
0 is an address signal, data signal, necessary for controlling each part,
and a control bus consisting of control signals.

The operation of this embodiment having the above configuration will be explained below with reference to the flowcharts shown in FIGS. 3 and 4.

FIG. 3 is a flowchart showing an example of the processing procedure of this embodiment stored in the ROM 13 and executed by the CPU 12.

When the power is turned on, the process first proceeds to step S1 in FIG.
Initialization processing is performed. Then, in the following step S2, the state of waiting for a key input from the keyboard is maintained. Step S
If some key human power is detected in step S3
Proceed to , determine the input key, and press the ruled line operation key 1.
If the key input is 1, the process proceeds to step S4, and if the input is by other keys, the process proceeds to step S5.

In step S4, ruled line operation processing is performed when the W I'll 8 production key 11 is pressed, and in step S5, character processing is performed in accordance with other input keys. In either case, when the process is completed, the process advances to step S2, which is in a state of waiting for key human power.

The details of the ruled line operation process in step S4 described above are shown in FIG.

In the ruled line operation process, first, in step 541, the cursor position of the document information in the document memory 15 is read from the cursor register 16. Then, in the following step S42, it is checked whether the read cursor position is within a frame surrounded by ruled lines in the document memory 15. If the cursor position is within the frame, the process advances to step S43, where the outermost frame among the frames surrounded by ruled lines is recognized, and then the next step S44
Then, the range (size) of this outermost frame is recognized and the required processing is executed. Specifically, the vertical size and horizontal size of the outermost frame, their positional relationship, etc. are determined.

Then, in step S45, it is determined whether a ruled line has already been drawn at the current cursor digit.

If a ruled line is drawn at the cursor digit, step S4
The process proceeds to step S44, where the ruled lines already drawn within the vertical range of the frame determined in step S44 are erased, and the process returns. If a ruled line is not drawn at the cursor digit, the process advances to step S47, where a ruled line is drawn at the cursor digit position within the vertical range of the frame determined in step S44, and then the process returns.

Further, if the cursor position is not within the frame surrounded by ruled lines in step S42, the process advances to step S4B, error handling is performed, and the process returns.

According to the process flow described above, a ruled line operation regarding a vertical ruled line can be performed by pressing only the ruled line operation key.

In addition, in the above explanation, an example was explained in which a vertical ruled line is drawn at the cursor position digit within a frame surrounded by ruled lines, but it is also possible to manually draw a horizontal ruled line key etc. on the keyboard 10, for example. Alternatively, drawing or erasing of horizontal ruled lines within the frame of the cursor digit can be performed using the same control as described above, or by program commands.

Furthermore, it is also possible to simultaneously draw and erase vertical and horizontal ruled lines within a frame centered on the cursor position.

[Effects of the Invention] As described above, according to the present invention, the cursor can be moved eight times before and after the range to be specified.
By simply pressing the ruled line operation key, it is possible to draw or delete ruled lines within a frame surrounded by ruled lines.
