Description

Description: TECHNICAL FIELD The present invention relates to a document processing device such as a word processor having a touch panel or a touch input device for inputting a handwritten pattern.

[Summary of the Invention] According to the present invention, the starting point and the ending point of a process are designated and the type of the process is designated from the position and shape of a pattern handwritten from a touch input device.

[Prior Art] Conventionally, when drawing a ruled line or an underline in a word processor, one method is to select a function for drawing a ruled line or an underline, then decide the type of the ruled line or the underline, and then from the start point to the end point. There is a method of drawing a ruled line or underline for each digit while moving the cursor up to.

As another method, after selecting the function for drawing a ruled line or underline, deciding the type of ruled line or underline, and specifying the start point and end point, between the specified start point and end point There is also a method to draw ruled lines or underlines at once.

[Problems to be Solved by the Invention] However, in any of the above methods, a large number of key operations are required, and the key operations must be performed in a predetermined order, which makes the operation complicated and troublesome. However, there was a risk of erroneous operation.

An object of the present invention is to make it possible to easily and surely perform a process of drawing a ruled line or an underline.

[Means for Solving Problems] Means of the present invention are as follows.

The touch input device 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) is for inputting a handwritten pattern from a touch panel. For example, a human body contact detection type in which a plurality of touch sensors are arranged on a matrix is used. It is a touch input device.

The first designating means 2 designates one of a start point and an end point of the processing from the position of the pattern handwritten and input from the touch input device 1, and a type of processing from the shape of the pattern.

The second designating means 3 designates the other of the starting point and the ending point of the processing.

The process executing means 4 is a CPU or the like that executes the type of processing specified by the first specifying means 2 between the start point and the end point specified by the first and second specifying means 2, 3. For example,
When the first designating means 2 selects an arrangement pattern corresponding to the pattern input from the touch input device 1 among a plurality of preset arrangement patterns, the processing executing means 4
Arranges the selected arrangement pattern between the start point and the end point designated by the first and second designating means 2 and 3. Further, the processing executing means 4 deletes the characters between the start point and the end point designated by the first and second designating means 2, 3.

[Operation] The operation of the means of the present invention is as follows.

Now, a case where a ruled line is drawn will be described as an example.

In this case, a ruled line pattern (one-dot chain line) having a desired shape is manually input from the touch input device 1 at one of the start point and the end point (start point position) of the portion where the ruled line is to be drawn.

As a result, the first designating means 2 causes the touch input device 1 to operate.
The starting point position is specified from the position of the ruled line pattern input by handwriting from, and the type of processing is specified from the pattern shape. For example, an arrangement pattern similar to the pattern input by handwriting is selected from a plurality of arrangement patterns stored in advance.

In this way, when the starting point position of the ruled line is designated by the handwriting input pattern, the ending point position of the ruled line is designated by the second designating means 3.

Then, the process execution means 4 arranges the arrangement pattern selected by the first designating means 2 between the start point and the end point designated by the first and second designating means 2, 3.

Therefore, by inputting the handwritten pattern, it is possible to specify the type of processing together with the starting point or the ending point of the processing, so that processing such as drawing a ruled line can be performed easily and reliably, and the entire processing can be performed efficiently.

[First Embodiment] An embodiment will be described below with reference to FIGS. 2 to 7.

Structure FIG. 2 is a block circuit diagram showing the basic structure of a word processor having a touch input device.

The CPU 11 controls various operations of this word processor in accordance with a microprogram stored in advance, and, for example, performs kana-kanji conversion or the like on the document data input from the key input unit 12 using the dictionary ROM 13 as necessary. Stored in the document memory 14 or converted from the document data read out from the document memory 14 into a print pattern using the character generator 15 and supplied to the print control unit 16 and the print unit 17
Print on the recording paper set in. Also, CPU11
Converts the input document data or the document data read from the document memory 14 into a display pattern using the character generator 15, gives the display pattern to the display control unit 18, and causes the display panel 19 to display it.

The display panel 19 is a large dot matrix type liquid crystal display panel for displaying input created document data and the like, and a touch panel 20 having a plurality of transparent touch electrodes (touch sensors) arranged in a matrix on the upper surface thereof. They are stacked. It is to be noted that, assuming that the entire display screen of the display panel 19 is divided for each character display area, the digit position corresponding to each display area depends on the coordinate position corresponding to the XY coordinate system whose origin is at the upper left part in the figure. Specified.

The touch panel 20 is a human body contact detection type touch panel that inputs a desired pattern by handwriting while touching the upper surface thereof with a finger or the like. The touch panel 20 corresponds to the xy coordinate system whose origin is at the upper left portion, and the 5 × 5 coordinate position for each character display area of the display panel 19 is the X coordinate detection unit 21 and the Y coordinate detection unit.
Detected by 22. Then, the X coordinate detection unit 21, Y
The coordinate position detected by the coordinate detection unit 22 is stored in the detected coordinate storage unit 23. That is, the handwritten pattern drawn on the upper surface of the touch panel 20 is converted into corresponding coordinate data along the locus and stored in the detected coordinate storage unit 23.
The detected coordinate storage unit 23 is configured by a random access memory, performs writing and reading operations of coordinate data under the control of the CPU 11, and the coordinate data read from the detected coordinate storage unit 23 is loaded into the CPU 11.

In this case, the CPU 11 takes in coordinate data corresponding to the handwritten pattern from the detected coordinate storage unit 23, and specifies the processing start point and the processing type and the processing end point by the position and shape of the pattern. In this embodiment, as the processing executed according to the pattern input by handwriting, the processing of drawing a ruled line or adding a shaded decoration is shown.

The working RAM 24 stores the start point, the end point, etc. of the processing, and the cut-out pattern storage unit 25 cuts out a pattern of a size corresponding to the one-character display area of the display panel 19 from the patterns input by handwriting. The cut-out pattern is stored, and the stored contents of the working RAM 24 and the cut-out pattern storage unit 25 are used when drawing a ruled line or performing a halftone decoration.

The character generator 15 (see FIG. 3) has an ordinary character font storage unit 15-1 and an arrangement pattern storage unit 15-2. The arrangement pattern storage unit 15-2 has three types of ruled lines. A pattern and three types of shaded patterns are stored.

Operation FIG. 4 is a flow chart showing the operation when a ruled line is drawn or halftone decoration is performed based on a pattern input by handwriting.

First, the case of drawing a ruled line will be described.

Now, as shown in FIG. 5 (a), while touching the touch panel 20 with a finger, draw a pattern indicating the type of ruled line at the starting point position where the ruled line is drawn, and touch the end point position of the ruled line.
The start point coordinate data (x ₁ , y ₁ ) and the end point coordinate data (x ₂ , y ₂ ) are detected by the X coordinate detection unit 21 and the Y coordinate detection unit 22 and stored in the detected coordinate storage unit 23 (step A
1).

Then, the CPU 11 fetches the X coordinates corresponding to the start point and the end point from the detected coordinate storage unit 23, sets the difference value in the A register in the working RAM 24 (step A2), and the value is displayed as one character on the display panel 19. It is checked whether the width is equal to or larger than the area width (character width) (step A3). That is, if less than the character width between the start point and the end point, the process becomes ineffective, the process proceeds to step A4 If more digits on the display panel 19 that includes the starting point position coordinates (x _1, y ₁₎ Position (X ₁ ,
Y ₁ ), that is, (3, 3) is calculated and stored in the working RAM 24 as a starting point digit (step A5). Then, the end point position coordinates (x _2, y ₂₎ digit position on the display panel 19 including the (X _2, Y _2), and calculates i.e. the (3,8) (step A6),
This is stored in the working RAM 24 as the end digit (step A7).

After the start point digit and the end point digit are obtained in this way, a pattern for one character is cut out from the detection coordinate storage section 23 from the start point position coordinates (x ₁ , y ₁ ) and cut out pattern storage section 25.
(Step A8). That is, the pattern in the area surrounded by the broken line in FIG. 5 (a) is cut out as shown in FIG. Then, the pattern stored in the cutout pattern storage unit 25 is read out, and an arrangement pattern similar to this is selected from the character generator 15 (step A9). FIG. 7 illustrates step A9, showing an arrangement pattern selected from the character generator 15 corresponding to the cutout pattern. If the cutout pattern has a shape as shown in FIG. The pattern is selected.

The ruled line pattern selected in this way is the Workin RA
The digits from the starting point digit (3, 3) to the ending point digit (8, 3) stored in M24 are arranged on the display screen of the display panel 19 in correspondence with each digit (step A10). Fig. 5 (b)
Indicates the arrangement state in this case.

Next, a case where half-tone decoration is performed will be described. In this case, as shown in FIG. 8 (a), while touching with a finger on the touch panel 20, a pattern indicating the type of shading is drawn at the start point position where shading is performed, and the end point position of the shading is touched. Then, the operation according to the flowchart of FIG. 4 described above is executed. As a result, as shown in FIG. 8 (b), the arrangement pattern (hatched mesh pattern) selected from the character generator 15 corresponding to each digit from the start point digit to the end point digit is displayed on the display screen of the display panel 19. Placed on top.

[Second Embodiment] This embodiment shows a case of deleting a character between a start point and an end point. As shown in FIG. 9 (a), the character on the touch panel 20 is deleted by touching it with a finger. Draw a pattern "" that specifies, and touch the end point of deletion.
Then, the characters from the starting point digit of the coordinate position (4, 3) to the ending point digit of the coordinate position (6, 3) are deleted and edited as shown in FIG. 9 (b).

Modified Application Examples The above embodiments have been described regarding ruled lines, shading, and deletion, but they can also be applied to a case where partial printing is performed by designating a print range of a document.

[Effect of the Invention] According to the present invention, the start point or the end point of the process can be specified by inputting the handwritten pattern, and the type of the process can be specified. It has an effect that can be efficiently performed.
