The input character data from the means (e) are input-processed by a processing means (h) with the designation classification by the means (g) to the document position corresponding to the touch position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device such as a computer, a word processor, or the like.

[Summary of the Invention] The present invention provides a document creation device equipped with a display means in which a transparent touch panel is disposed on a display screen. By specifying how data is to be input and processed for already created document data, the processing content can be specified using a transparent touch panel.

[Prior Art] Conventionally, in document creation devices, inputting document data, specifying a position on a display screen, and instructing processing contents such as insertion 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 make position specification easier, 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. A document creation device equipped with a point input device that allows users to input points has appeared on the market.

[Problems to be Solved by the Invention] However, the transparent touch panel is used only for specifying the position, and when instructing the processing contents, the processing position is specified using the transparent touch panel, and then a predetermined key on the keyboard is used to specify the processing position. It is necessary to instruct processing contents such as insertion, and the instructions for processing contents are complicated.

An object of the present invention is to expand the conventional limited functions of a transparent touch panel and to enable the transparent touch panel to instruct processing contents.

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

Storage means a (see the functional block diagram in 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 disposed on the display screen of the display means and is made of a transparent member so that the displayed content can be seen from above.

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

The input means e is, for example, a key input section for inputting various character data.

The determining means f determines that the input of character data by the input means e is
It is determined whether or not the same position on the transparent touch panel C is being touched.

The specifying means g specifies the type of input processing, for example, input processing by insertion or input processing by overwriting, based on the determination result by the first determining means f.

The processing means performs an input process on the character data inputted by the input means e to a document position corresponding to the touch position of the document data in the storage means a with the type designated by the designation means g. .

[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.

If you want to modify the displayed document data, you can insert desired character data into the already created document data, or delete the previous character data and overwrite it with another character data. If desired, first touch the position on the document data to be corrected with a finger via the transparent touch panel C. Then, the touch position is detected by the detection means d. After that, depending on the format you want to input, that is, insert format or overwrite format, you can either remove your finger from the transparent touch panel (in the example, the overwrite format is used), or keep it touched (in the example, the finger will be in the overwrite format). In any of these states, the input means e
When character data is input, the determining means f determines this, and the specifying means g specifies the desired type of input processing. Then, the input character data is inputted by the processing means to the document position on the document data corresponding to the detected touch position in the type specified by the specifying means g.

Therefore, by only one touch on the transparent touch panel C and a character data input operation, the input character data can be inputted according to the desired type of input processing.

[Example] An example will be described below with reference to FIGS. 2 to 7.

Configuration FIG. 2 is a configuration diagram of a document creation device according to a seventh embodiment. This document creation device performs various processes such as kana-kanji conversion on the 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. In addition, by touching a transparent touch panel 4A, which will be described later, the contents of processing such as insertion and overwriting, and the processing position are 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.
As shown by 0 and Δ, they are arranged in a substantially matrix structure, and the display contents of the liquid crystal display section 4B below can be seen. Also, the touch switch group marked with .corresponds to the center position (on the character) of one character area on the display screen of the liquid crystal display section 4B, the touch switch group marked with 0 corresponds to the character amount position, and the touch switch group marked with Δ The touch switch groups correspond to the line spacing positions. As shown in Fig. 3, the coordinate data of the touch switch group marked with a mark on the character is indicated by an even number for both the X component and the y component, and the coordinate data of the touch switch group marked with an O mark on the character amount is shown as an even number. , the X component is shown as an odd number and the y component is shown as an even number, and the coordinate data of the touch switch group marked with Δ on the line spacing is shown as an even number for the X component and an odd number for the y component.

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 coordinate 9x component data and y component data are overwritten in the X register 8 and y register 9, respectively, and when the sampled touch switch is off, the X register 8. Clear the contents of y register 9. Then, the address data, etc. on the document memory 3 of the character displayed at the position corresponding to the turned-on touch switch is calculated under the control of the CPU 2 and stored in the document address buffer IO.

Further, the CPU 2 determines the continuity of touches on the O-marked touch switch portion corresponding to the amount of characters on the transparent touch panel 4A based on the contents of the X register 8 and the y register 9, and if there is continuity, performs insertion processing. Specify , and if there is no continuity, specify overwrite processing. These processes are performed sequentially starting from the position in the document memory 3 indicated by the address data in the document address buffer IO.

Operation Next, the operation of this embodiment will be explained with reference to FIGS. 4 to 7.

FIG. 4 is a flowchart showing the operation of the embodiment, and the processing in steps S2 to S5 corresponds to FIG.
Processes 6 to 513 correspond to FIG. 6, and steps 513 to 513 correspond to FIG.
The process 816 corresponds to FIG.

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 y register 9, respectively (Step 51 in Figure 4).Next, the CPU 2 analyzes the coordinate data to store the touch switch one character above (as shown in Figure 3).・It is determined whether or not the touch switch marked with the mark) has been turned on (step S2). As a result, when it is determined that both the X component data and the y component data are even numbers and that the touch switch marked with the character has been turned on ( Refer to FIG. 5(a)), the process proceeds to step S3, and calculates the address of the above character (display character) on the document memory 3,
Store it in the document address buffer 10. Then, the cursor is displayed at the position of the touched display character (step 54).Next, the overwrite input mode is set, and the input character data is transferred to one document memory 3 at the address in the document address buffer lO. The contents of the document address buffer IO are incremented by "1" each time one character is overwritten (step S5). The cursor is shifted one character at a time (see FIG. 5(b)).

In this way, by touching a character, overwriting processing from that touch position is specified internally, so
Overwriting instructions can be easily given.

If it is determined in step S2 that the touch is not on a character, the process advances to step S6, and a determination is made as to whether the touch was between one character or not based on whether the X component data is an odd number and the y component data is an even number. As a result, if it is determined that a space between characters has been touched, the address of the displayed character on the right side in the document memory 3 is calculated and stored in the document address buffer IO (step S7), and
An insertion cursor like the symbol - shown in FIG. 6(a) is displayed below the displayed characters on the right side, and the insertion mode is set (step 58).Next, what is determined in step S6 It is determined whether or not the same character interval, that is, the character interval to the left of the displayed insertion cursor, is still being touched (continuity of touches at the same position) (step S9). As shown in figure (a), if the same character space is still touched, 1
Step 5IO) to determine whether character data is input or not;
If there is an input, the input character data is inserted at the insertion cursor position (step 5ll), and the contents of the document address buffer IO are incremented by "1" (step 512), and the process returns to step S8. In this step S8, an insertion cursor is displayed at the position corresponding to the address in the document address buffer IO, and since this address was incremented by "1" in step 512, the insertion cursor is shifted to the right by one character. Then, the process from step S9 onwards is repeated, and the sixth
As shown in Figure (b), the input character data is inserted one after another.

If it is determined in step S9 that there is no touch, the process proceeds to step S13, where an overwrite input mode is set. As a result, the cursor assumes a normal cursor shape, as indicated by - in FIG. 6(C). Therefore, Fig. 6 (C
), inputting rbJ overwrites ``rf3'' at the current cursor position, and shifts the cursor to the right by one character (see FIG. 6(d)).

In this way, if you input character data while touching the space between characters, the input character data will be sequentially inserted to the right position between the touched characters, that is, the transparent touch panel 4AK will The processing details are instructed.

Note that the above insertion process assumes an operation mode in which character data to be inserted is manually input using the keys Ill with the left hand while touching the space between characters with the right hand. It is also possible to adopt an operation form in which the user momentarily touches the space between characters, then uses both hands to input the character data to be inserted from the key input section 1, and then touches the same character space again. Even in this operation mode, since touch detection is performed under the control of the sampling circuit 6, the CPU 2 determines that there is continuity of touches to the same position.

If it is determined in step S6 that the touch is not between one character, the touch is between lines as shown in FIG. In between, one line of line data (blank data) is inserted into the document memory 3 (Fig. 7(b)).
(see step 515), calculates the address on the document memory 3 corresponding to the lower coordinates between the touched lines and stores it in the document address buffer lO (step 515), and moves the cursor to the position on the display screen corresponding to the address position. (Step S16) That is, as shown in FIG. 7(b), the cursor is displayed in the blank area directly below the touched line.

Thereafter, the process advances to step S13, where an overwrite input process is executed. In other words, when one character data is input in the state shown in FIG. 7(b), the input character data is stored in the document memory 3. On the other hand, the information is overwritten sequentially starting from the cursor position (see 7th rI!J(C)).

In this way, a line is inserted by touching between lines.

[Effects of the Invention] According to the present invention, not only the processing position but also the processing content can be instructed using the transparent touch panel disposed on the display screen, thereby facilitating input operations.
