Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to document editing devices such as office computers and word processors.

[Summary of the Invention] The present invention provides a document editing device equipped with a display means in which a transparent touch panel is disposed on one display screen. By specifying , editing instructions can be given using a transparent touch panel.

[Prior Art] Conventionally, in document editing devices, inputting document data, specifying a position on a display screen, and editing instructions such as insertion, deletion, and movement have generally been performed using a keyboard.

However, when specifying a position using this keyboard, the cursor must be moved to the desired position by holding down the cursor movement key, making it difficult to specify the desired position directly. there were.

Therefore, in order to easily specify one position, a transparent touch panel is placed on the display screen, and by touching the desired position with a finger, the position on the display screen can be read, and the desired position can be directly specified. Document editing devices have appeared that are equipped with point input devices that allow users to input points.

[Problems to be Solved by the Invention] However, the transparent touch panel is used only for specifying a position, and when giving an editing instruction, the editing position is specified using the transparent touch panel, and then the insertion, insertion, etc. It is necessary to instruct the type of editing such as deletion, and the editing instructions are complicated.

An object of this invention is to expand the conventional limited functions of a transparent touch panel and to enable editing instructions to be given using the transparent touch panel.

[Means for solving problems] The means of this invention are as follows.

Storage means a (see the functional block diagram of FIG. 1, the same applies hereinafter) stores document data.

The display means (a) displays the document data stored in the storage means (a).

The transparent touch panel C is arranged on the display screen of one display means and is made of a transparent member so that one display content can be seen from above.

The detection means d detects a touch position on the transparent touch panel C.

The determining means e determines whether the display position on the display screen of the display means corresponding to the touch position detected by the detecting means d is on a character.

The specifying means f specifies the type of editing process based on the determination result by the determining means e.

The editing processing means g performs the type of editing processing specified by the specifying means f on the document data stored in the storage means a.
Execution is performed based on the position corresponding to the above-mentioned touch position.

[Work] The operation of the means of this invention is as follows.

The document data stored in the storage means a is displayed on the display means A, and the displayed content is visible through the transparent touch panel C. Therefore, when a desired position is touched via the transparent touch panel C, the touch position is detected by the detection means d. Then, when the determining means e determines whether the display position on the display screen corresponding to the touch position is on a character or not, the specifying means f specifies the type of editing process based on the determination result. 0 For example, when it is determined that the position is one character above, deletion processing is specified, and when it is determined that it is not one character above, shift processing is specified. Therefore, the editing processing means g performs the deletion processing, shift processing, etc. specified by the specifying means f on the document data stored in the storage means a, with reference to the position corresponding to the above-mentioned target position. .

Therefore, the conventional limited functions of the transparent touch panel can be expanded, and editing instructions can be given using the transparent touch panel.

[Example] An example will be described below with reference to FIGS. 2 to 8.

做－譞 FIG. 2 is a block diagram of a document editing device according to an embodiment.

This document editing device performs various processes such as kana-kanji conversion on character data input from the key input section 1 under the control of the CPU 2, and stores the processing results as document data in the document memory 3. It is stored, displayed on the display section 4, and printed on the printing section 5. Furthermore, by touching a transparent touch panel 4A, which will be described later, the type of editing such as deletion, insertion, and shift for one document data can be specified, and the editing position can be specified.

The display section 4 includes a transparent touch panel 4A and a liquid crystal display section 4B, and the transparent touch panel 4A is arranged on the display screen of the liquid crystal display section 4B. This transparent touch panel 4A has a group of touch switches made of transparent members on a flexible transparent film as shown in FIG.
0. As shown by Δ, they are arranged in a matrix structure, and the display contents of the liquid crystal display section 4B below can be seen. Further, as shown by hatching in FIG. 3, a square area surrounded by four touch switches marked with Δ corresponds to one character area on the display screen of the liquid crystal display section 4B. In other words, the touch switch group marked with .corresponds to the center position of the characters displayed on the display screen, the touch switch group marked with O corresponds to the character amount position, and the touch switch group marked with Δ corresponds to the line spacing position. It corresponds to As shown in Fig. 3, the coordinate data of the touch switch group marked with .
Both components are shown as even numbers, and the coordinate data of the touch switch group marked with O on the character amount is shown as an odd number for the X component, and an even number as the y component, and the coordinate data of the touch switch group marked as Δ on the line spacing is Both the component and the y component are indicated by odd numbers.

The sampling circuit 6 always samples the touch switches one by one cyclically. The touch coordinate detection unit 7 first checks the on/off state of the touch switch sampled by the sampling circuit 6. When the sampled touch switch is on, the X-component data and y-component data of that coordinate are overwritten in the X register 8 and X register 9, respectively, and when it is off, the contents of the X register 8 and X register 9 are overwritten. Clear. Then, the address data on the document memory 3 of the character displayed at the position corresponding to the turned-on touch switch is
It is calculated under the control of the CPU 2 and sequentially stored in the document address buffer 10.

The touch switch coordinate data related to ON written in the X register 8 and the X register 9, and the address data stored in the document address buffer 10 are used as information for specifying the editing position and the type of editing. . The contents of the document address buffer 10 are erased after being utilized for editing processing.

Next, one editing processing operation will be explained with reference to FIGS. 4 to 8.

FIG. 4 is a flowchart showing the editing processing operation. Through the processing of steps S3 to Sll, deletion as shown in FIG. 5 is performed, and from the processing ratio of steps 312 to 318, deletion as shown in FIG. A shift takes place.

The following is a step-by-step explanation.

When the transparent touch panel 4A is touched with a finger or the like, a touch switch located at the touched area is turned on. Then, the coordinates of the touch switch related to the on state are detected by the touch coordinate detection section 7, and the X component data, y
The component data is stored in the X register 8 and the X register 9, respectively (Fig.
By analyzing the coordinate data, it is determined whether or not the touch switch on the character (the touch switch marked with a * shown in FIG. 3) has been turned on (step 32). As a result, when it is determined that both the X component data and the y component data are even numbers, and the touch switch on the character is turned on as shown in FIG. The address of (display character) in the document memory 3 is calculated and stored in the document address buffer 10. Then, the character corresponding to the turned-on touch switch is displayed in reverse video (step S4), and the sampling circuit 6 is sent to the touch switch between characters and between lines other than the touch switch on the character (O1Δ shown in FIG. 3). The hatched area in FIG. 5 is the inverted area (step S5).

Next, the presence or absence of a touch on the transparent touch panel 4A is determined by
This is determined by referring to the register 8 and the X register 9 (step S6). If it is determined that there is a touch, it is determined whether the touch switch related to the touch is different from the previous touch (STELLA 7'S7). At this time, the identity is determined by referring to the contents of the X register 8, the X register 9, and the document address buffer 10. In addition, since sampling of touch switches between characters and between lines is prohibited in step S5, all touch switches whose touch is detected in step S6 are
It is literally a touch switch.

When it is determined that a different touch switch on a character has been turned on, the address on the document memory 3 of the displayed character corresponding to the touch switch related to the current touch is calculated and stored in the document address buffer ylO (step S9). , and displays the displayed characters corresponding to the touch switch related to the current touch in reverse video (step S10, see FIG. 5(b)).
, return to step S6. On the other hand, in step s7,
If it is determined that they are the same, the process immediately returns to step S6.

If it is determined in step S6 that there has been no touch for a predetermined period of time or more, the process proceeds to step S11, where the character in the document memory 3 indicated by the address stored in the document address buffer 10 is erased, and the erased area is The characters in the later area are entirely shifted by the number of characters to be erased to fill the erased area, and then transferred to the document address buffer l.
.

Clear the contents of. As a result, Fig. 5(b) and (C)
As shown in , the character that was touched and highlighted,
"B", "C", and rDJ have been deleted, and "E" was displayed after "D".

"F" is shifted to the left by the number of erased characters, and the characters are packed together.

In this way, simply by touching the character to be erased via the transparent touch panel 4A, erasure and deletion including filling of the erased area with characters are executed. That is, deletion as an editing mode using only the transparent touch panel 4A,
It becomes possible to specify the deletion range and the deletion range, making the instruction operation easier.

In step S2, when it is determined that the touch switch turned on by the touch operation is a touch switch between characters (see FIG. 6(a)), the process advances to step S12. The touch switch to the right of the touch switch (the touch switch on the text)
The address on the document memory 3 of the display character corresponding to is calculated and stored in the document address buffer 10.
Shift processing is performed by inserting space data into the area of the document memory 3 indicated by the address stored in the document address buffer 10 (see FIG. 6(b));
The contents of the document address buffer 10 are cleared (step 313).

Then, the sampling circuit 6 is prohibited from sampling touch switches between characters and between lines other than touch switches on characters (step 514).Next, the presence or absence of a touch on the transparent touch panel 4A is determined (step 515). When it is determined that a touch has been made, it is determined whether the touch switch related to that touch is different from the previous touch (step 316), and if the result is different, a document of display characters corresponding to the touch switch related to the current touch is displayed. The address on the memory 3 is calculated and stored in the document address buffer 10 (step 517). Then, shift processing is performed by inserting space data into the area of the document memory 3 indicated by the address stored in the document address buffer 10 (see FIG. 6(c)), and the contents of the document address buffer 10 are Clear Step 518
), the process returns to step 315.

On the other hand, if it is determined in step 316 that they are the same, the process immediately returns to step S15. If it is determined in step S15 that there is no touch for a predetermined period of time or more, the process ends.

In this way, when you first turn on the touch switch one character above, the editing content is determined to be a shift, and the entire character to the right of the turned on touch switch is shifted by one character. , each time a touch switch on a character is turned on, the entire character to the right of the turned-on touch switch is shifted one character at a time. In other words, all instructions necessary for the shift process can be given using only the transparent touch panel 4A.

Note that the present invention is not limited to the above-described embodiments. For example, as shown in FIGS. 7 and 8, an editing block is specified by specifying two points, a start point and an end point, and the touch switch at the start point is type (literally).

It is also possible to specify the type of editing by character spacing, line spacing). That is, as shown in Figure 7(a), when you specify the touch switch part on the character as the starting point, a block (as shown in Figure 7(a)) whose diagonal points are the specified starting point and ending point is specified. As shown in FIG. 7(b), the contents of the block are erased and the erased area is filled with characters, as shown in FIG. 7(b).

In addition, as shown in Fig. 8(a), when the touch switch part on the line spacing is specified as the starting point, a block with the specified starting point and ending point as diagonal points (Fig. 8(,lL)
It is determined that the frame opening is specified for the bold line portion shown in FIG.

[Effects of the Invention] According to the present invention, it is possible to instruct not only the editing position but also the type of editing using the transparent touch panel disposed on the display screen, thereby facilitating input operations.
