Description

The present invention relates to a document creation device such as an office computer or a word processor.

[Points of the Invention] In the present invention, in a document creation apparatus including a display means in which a transparent touch panel is arranged on a display screen, a character input this time is determined depending on whether there is continuity of touch at the same position on the transparent touch panel. By designating how data is input-processed with respect to already created document data, the processing content can be designated by the transparent touch panel.

[Prior Art] Conventionally, in a document creation device, input of document data,
A keyboard is generally used to specify a position on a display screen and to instruct processing contents such as insertion. However, when specifying the position using this keyboard, it is necessary to move the cursor to the desired position by holding down the cursor movement key, and it is not possible to directly specify the desired position, making the specifying operation cumbersome. there were.

Therefore, in order to easily specify the position, a transparent touch panel is provided on the display screen, and the position on the display screen is read by touching the desired position with a finger and the desired position is specified directly. A document creating apparatus equipped with a point input device made possible has appeared.

[Problems to be Solved by the Invention] However, the transparent touch panel is used only for position designation, and when a processing content is instructed, the processing position is designated by the transparent touch panel, and then a predetermined key on the keyboard is used. Since it is necessary to instruct the processing content such as insertion, the instruction of the processing content is complicated.

An object of the present invention is to expand conventional limited functions of a transparent touch panel so that the processing content can be instructed by the transparent touch panel.

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

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

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

The transparent touch panel c is arranged on the display screen of the display means b, and is composed of a transparent member so that the display content can be seen from above.

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

The input unit e is, for example, a key input unit and inputs various character data.

The determining unit f determines whether or not the character data input by the input unit e is performed while the transparent touch panel c is being touched at the same position.

The designation means g designates the type of input processing, for example, the type of input processing by insertion or input processing by overwriting, based on the discrimination result by the discrimination means f.

The processing unit h executes the input process of the document data input by the input unit e to the document position corresponding to the touch position of the document data in the storage unit a in the type designated by the designating unit g.

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

The document data written in the storage means a is displayed on the display means b, and the display content is visible through the transparent touch panel c.

If you want to modify the currently displayed document data, that is, insert the desired character data on the already created document data, or erase the previous character data and overwrite another character data. If you want to do so, first move the position on the document data
Touch with your finger through. Then, the touch position is detected by the detecting means d. After that, depending on the desired input format, that is, the insertion format or the overwriting format, either the touched finger is released from the transparent touch panel (in the embodiment, it is the overwriting format) or the touch is kept (in the embodiment, in the overwriting format). It will be an insertion format). When character data is input by the input means e in any of these states, the determination means f determines that the character data is input, and the designation means g designates the desired type of input processing. Then, the input character data is input by the processing unit h to the document position on the document data corresponding to the detected touch position in the type specified by the specifying unit g.

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

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

Structure FIG. 2 is a block diagram of a document creating apparatus according to an embodiment. This document creation device performs various processes such as kana-kanji conversion on the character data input from the key input unit 1 under the control of the CPU 2, and the processed results are stored in the document memory 3 as document data. It is for storing, displaying on the display unit 4, and printing on the printing unit 5. Further, by touching a transparent touch panel 4A described later, processing contents such as insertion and overwriting, and a processing position are specified.

The display unit 4 has a transparent touch panel 4A and a liquid crystal display unit 4B, and the transparent touch panel 4A is arranged on the display screen of the liquid crystal display unit 4B. This transparent touch panel 4A has a structure in which touch switch groups made of transparent members are arranged in a substantially matrix on a flexible transparent film, as indicated by ●, ○, and △ in FIG. The display contents of the liquid crystal display section 4B below it can be seen. The touch switch group indicated by ● corresponds to the center position (on the character) of one character area on the display screen of the liquid crystal display unit 4B, the touch switch group indicated by ○ corresponds to the position between characters, and the △ mark indicates The touch switch group of
Corresponds to the line spacing. Then, as shown in FIG. 3, the coordinate data of the touch switch group indicated by ● on the character is
Both the x and y components are indicated by even numbers. The circles above the characters indicate the coordinate data of the touch switch group. The coordinate data of the x component is indicated by the odd numbers and the y component is even, and the coordinates of the touch switch group indicated by the triangles between the lines are indicated. The data is shown with an even x component and an odd y component.

The sampling circuit 6 constantly samples one touch switch cyclically at a time. The touch coordinate detecting 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 the coordinates are overwritten in the x-register 8 and the y-register 9, respectively, and when it is off, the contents of the x-register 8 and the y-register 9 are written. To clear.
Then, the address data and the like on the document memory 3 of the character displayed at the corresponding position of the touch switch that is turned on are calculated under the control of the CPU 2 and stored in the document address buffer 10.

Further, the CPU 2 uses the contents of the x register 8 and the v register 9 to indicate the correspondence between the characters for the transparent touch panel 4A.
Determine the continuity of touch to the touch switch part of the mark,
When there is continuity, insert processing is specified, and when there is no continuity, overwrite processing is specified. These processes are sequentially performed from the position on the document memory 3 indicated by the address data in the document address buffer 10.

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

FIG. 4 is a flow chart showing the operation of the embodiment,
The processing of steps S2 to S5 corresponds to FIG. 5, and steps S6 to
The processing of S13 corresponds to FIG. 6, and the processing of steps S13 to S16 corresponds to FIG.

 Hereinafter, description will be made in order.

When touching the transparent touch panel 4A with a finger or the like, the touch switch located at the touched portion is turned on. Then, the coordinates of the touch switch that is turned on are detected by the touch coordinate detection unit 7, and the x component data and y
The component data are stored in the x register 8 and the y register 9, respectively (step S1 in FIG. 4). Next, the CPU 2 analyzes the coordinate data to determine whether or not the touch switch on the character (the touch switch with the mark ● shown in FIG. 3) is turned on (step S2). As a result, both the x-component data and the y-component data are even numbers, and when it is determined that the touch switch on the character is turned on (see FIG. 5 (a)), the process proceeds to step S3, and the character (display character) is displayed. The address in the document memory 3 is calculated and stored in the character address buffer 10. Then, the cursor is displayed at the position of the touched display character (step S4).
Next, the overwriting input mode is set, and the input character data is sequentially overwritten in the document memory 3 from the address position (cursor position, that is, the touch position) in the document address buffer 10 (step). S5). On this occasion,
Every time one character is overwritten, the content of the document address buffer 10 is incremented by "1" and the cursor is shifted by one character accordingly (see FIG. 5 (b)).

In this way, by touching a character, the overwrite process from the touched position is internally specified, so that the overwrite instruction can be easily performed.

If it is determined in step S2 that the characters are not touched, the process proceeds to step S6, and it is determined whether the character space is touched or not depending on whether the x component data is an odd number and the y component data is an even number. To judge. As a result, when it is determined that the space between the characters is touched, the address of the display character on the right side is calculated in the document memory 3 and stored in the document address buffer 10 (step S7). Then, as shown in FIG. 6 (a), below the display characters on the right side. An insertion cursor such as is displayed and the insertion mode is set (step S8). Next, it is determined whether the same character as that determined in step S6, that is, the character on the left side of the displayed insertion cursor is still touched (continuity of touch at the same position). Yes (step S9). As a result, as shown in FIG. 6 (a), when the same character is still touched, it is judged whether or not the character data is input (step S10), and when the character is input, it is input. The inserted character data is inserted at the insertion cursor position (step S11). Then, the content of the document address buffer 10 is incremented by "1" (step S1
2), return to step S8. In step S8, the insertion cursor is displayed at the position corresponding to the address in the document address buffer 10. Since this address has been incremented by "1" in step S12, the insertion cursor is shifted to the right by one character. . Then, the processing from step S9 is repeated, and the input character data is sequentially inserted as shown in FIG. 6 (b).

If it is determined in step S9 that there is no touch, the process proceeds to step S13 to set the overwrite input mode. As a result, the cursor has a normal cursor shape as shown by _ in FIG. 6 (c). Therefore, if "b" is input in the state of FIG. 6 (c), "b" is overwritten on "B" at the current cursor position, and the cursor is shifted to the right by one character (Sixth). See FIG. (D)).

In this way, when character data is input while the characters are being touched, the input character data is sequentially inserted into the right position between the touched characters. That is, the processing content is instructed by the transparent touch panel 4A.

Note that the insertion process is assumed to be performed by, for example, inputting the character data to be inserted from the key input unit 1 with the left hand while touching the spaces between the characters with the right hand. It is also possible to adopt a mode of operation in which characters are momentarily touched, then the character data to be inserted is input from the key input unit 1 with both hands, and the same characters are touched again. Even in this operation mode, since the touch detection is performed by the control of the sampling circuit 6, the CPU 2 determines that the touch at the same position has continuity.

When it is determined in step S6 that there is no inter-character touch, the inter-line touch as shown in FIG. 7 (a) has occurred. Therefore, the process proceeds to step S14, and the upper and lower lines between the touched lines are connected. In between, the line data (blank data) for one line is inserted into the character memory 3 (see FIG. 7 (b)). Then, the address on the character memory 3 corresponding to the lower coordinate between the touched lines is calculated and stored in the document address buffer 10 (step S15), and the cursor is displayed at the position on the display screen corresponding to the address position. Yes (step S16). That is, as shown in FIG. 7 (b), the cursor is displayed in the blank area directly below the touched line. After that, the process proceeds to step S13, and the overwrite input process is executed. That is, when the character data is input in the state of FIG. 7B, the input character data is overwritten in the document memory 3 sequentially from the cursor position (see FIG. 7C). ).

In this way, a line is inserted by touching the upper part of the upper part.

[Effect of the Invention] According to the present invention, the transparent touch panel provided on the display screen can indicate not only the processing position but also the processing content, and the input operation becomes easy.
