Description

The present invention relates to a character processing device that displays input character string data and converted character string data on a display screen.

2. Description of the Related Art Conventionally, in a document processing apparatus, not only input of document data, but also position designation on a display screen and instruction of various processing contents are performed by individual keys on a keyboard. .

[Problems to be Solved by the Invention] Therefore, when creating a document, first specify the document input start position by moving the cursor with a cursor movement key or the like, then input the kana character data, and use the conversion key or the like. Instructs the Kana-Kanji conversion process and, if the conversion performed based on the instruction is not the desired one, designates it by moving the cursor one character at a time using a cursor movement key or the like, and specifying the next candidate key or the like. Therefore, it is necessary to operate the corresponding key each time, for example, to instruct re-conversion to the next candidate, and the desired document content cannot be obtained quickly.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to quickly obtain desired document contents.

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

Input means for inputting character string data, conversion means for converting input character string data input from the input means into corresponding conversion candidate character string data, character string data input from the input means, or Display means for displaying the conversion candidate character string data converted by the means on a display screen, detection means for detecting a touch instruction operation and the instruction operation position on the display screen, and detecting the touch instruction operation If the designated operation position is a position above the input character string data, the control means activates the conversion means and converts the designated input character string data into corresponding conversion candidate character string data. When the touch operation is detected and the pointing operation position is a position on the conversion candidate character string data, the specified conversion candidate character string data is converted into another conversion candidate character string data. A second control means for changing the auxiliary string, the.

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

It is assumed that character string data input from the input means or conversion candidate character string data converted by the conversion means is displayed on the display screen, and the detection of a touch instruction operation on the display screen is performed. At this time, if the designated operation position is a position on the input character string data, the conversion means is started, and the designated input character string data is converted into corresponding conversion candidate character string data. When the touch operation is detected and the pointing operation position is a position on the conversion candidate character string data, the designated conversion candidate character string data is changed to another conversion candidate character string.

Embodiment An embodiment will be described below with reference to FIGS. 1 to 7.

1. Configuration FIG. 1 is a configuration diagram of a document processing apparatus according to one embodiment. This document processing device performs various processes such as kana-kanji conversion on the character data string input from the key input unit 1 under the control of the CPU 2 by referring to the conversion dictionary 3, for example. Is stored in the document memory 4 as document data,
This is displayed on the display unit 5 and applied at the printing unit P. Further, by touching a transparent touch panel 5A, which will be described later, designation of predetermined processing content and designation of a processing position in accordance with a processing stage at that time are performed.

The key input unit 1 has keys such as a kana character key 1A for inputting kana character data and a determination key 1B for instructing to determine a kana-kanji conversion result as the conversion result. The kana character data string input by operating the kana character key 1A is temporarily stored in the input buffer 6. Then, when the kana-kanji conversion processing is performed on the kana character data string, the processing result is stored in the conversion candidate buffer 7. Then, with the contents in the conversion candidate buffer 7,
When the confirmation instruction is issued, the content is stored in the document memory 4.

The display unit 5 has a transparent touch panel 5A and a liquid crystal display unit 5B, and the transparent touch panel 5A is provided on a display screen of the liquid crystal display unit 5B. The transparent touch panel 5A has a structure in which a group of touch switches made of a transparent member are arranged in a matrix on a flexible transparent film.
Can be displayed.

The sampling circuit 8 constantly samples the touch switches one by one cyclically. The touch coordinate detecting unit 9 first checks the on / off state of the touch switch sampled by the sampling circuit 8.
When the sampled touch switch is on, the coordinate data is output to the CPU 2. Then, address data and the like on the document memory 4 of the character displayed at the position corresponding to the turned on touch switch are calculated under the control of the CPU 2 and stored in the document pointer 10.

The cursor pointer 11 designates the position of a cursor displayed on the display screen of the liquid crystal display unit 5B. The flag F indicates the processing stage of the document processing. “0” indicates the initial state where no processing has been performed, or the kana-kanji conversion processing for the kana character data string relating to the previous input is determined. , Indicates that the next Kana character data string has not been input yet. Further, the content “1” of the flag F indicates a state in which the kana-kanji conversion processing for the input kana character data string has not been performed yet.
Further, the content “2” of the flag F indicates a state where the kana-kanji conversion processing has been performed and the determination processing has not been performed yet.

The flag F is used for designating the content of a process when instructing a predetermined process based on a touch on the transparent touch panel 5A.

FIG. 3 is an external view of the document processing apparatus according to this embodiment. As illustrated, the display unit 5 and the other components (main body side) are formed on separate housings, and these are electrically connected by a flat cable 100 and configured to be spread on a desk. ing. Therefore, the left hand specializes in instructing the processing contents with the transparent touch panel 5A,
With the right hand, it is easy to specialize in data input by the key input unit 1. Of course, using both hands, key input unit 1
, And then touch the transparent touch panel 5A with the left hand to instruct processing contents. In addition, the housing on which the display unit 5 is formed is configured to be capable of being folded in two. In this folded state, the casing is overlaid on the key input unit 1 on the main body side so that the casing can be made compact and easily carried. It is configured.

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

FIG. 3 is a flowchart showing the operation of instructing the processing contents. The processing in steps S2 to S5 corresponds to FIG. 4, the processing in steps S6 to S10 corresponds to FIG. 5, and the processing in steps S11 to S14.
Corresponds to FIG.

 Hereinafter, description will be made in order.

When the transparent touch panel 5A is touched 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 detecting unit 9 (step S in FIG. 3).
1). Next, it is determined whether or not the content of the flag F is "0" (step S2). When it is determined that the value is “0”, the kana-kanji conversion process for the initial state as shown in FIG. 4A or the kana character data string relating to the previous input is determined. This shows a state in which the input of the next kana character data string has not yet been made. Therefore,
In this case, in order to perform the cursor moving process, first, in step S3, the cursor is moved so as to specify the position on the display screen of the liquid crystal display unit 5B corresponding to the touch coordinates detected by the touch coordinate detecting unit 9. Update the pointer 11.
Next, as shown in FIG.
Display the cursor at the position specified in step 11 (step S
4) The document pointer 10 is updated to correspond to the currently displayed (moved) cursor position (step S5).

That is, when the transparent touch panel 5A is touched before the input of the kana character data string, the cursor movement to the touch position is instructed.

On the other hand, when it is determined in step S2 that the content of the flag F is not “0”, the process proceeds to step S6, and further,
It is determined whether or not the content of the flag F is "1". As a result, when it is “1”, as shown in FIG.
This means that a touch has been made in a state where an unconverted Kana character data string exists.
An unconverted kana character data string related to touch as shown in FIG. 2B is converted to kana-kanji characters (step S7). next,
The kana-kanji conversion result is stored as a conversion candidate in the conversion candidate buffer 7 (step S8) and displayed (step S8).
9: See FIG. 5 (c)). Then, "2" is set to the flag F.

That is, when a touch is made on the unconverted kana character data string, an instruction for kana-kanji conversion processing has been given for all unconverted kana character data strings in the input buffer 6 including the touched portion. Become.

On the other hand, when it is determined in step S6 that the content of the flag F is not "1", that is, when the content of the flag F is "2", the kana-kanji conversion is performed, and then the finalizing process is performed. Means no.

Therefore, when a touch is made in this state (see FIG. 6 (a)), first, a conversion candidate of one phrase in the conversion candidate buffer 7 corresponding to the touch coordinates is designated to output the next candidate (see FIG. 6A). Step S11). Next, it is converted to the next candidate corresponding to the designated conversion candidate (step S12), and the next candidate is stored in the corresponding area of the conversion candidate buffer 7 (step S13) and displayed (step S14: FIG. 6). (B)).

That is, if the conversion candidate is touched after the kana-kanji conversion has been performed and the finalization process has not been performed, the conversion to the next candidate is instructed.

Then, with the Kana-Kanji conversion process performed,
When 1B is operated, all contents in the conversion candidate buffer 7 are stored in the position of the document memory 4 indicated by the document pointer 10 (step S51 in FIG. 7). Thereafter, the contents of the input buffer 6 and the conversion candidate buffer 7 are cleared (step S52), and the flag F is reset (step S5).
3).

As described above, when the touch on the transparent touch panel 5A is performed, an appropriate processing content is instructed according to the document processing stage at that time, and desired document content can be obtained quickly.

[Effects of the Invention] According to the present invention, if a touch instruction operation position on a display screen on which input character string data or converted character string data is displayed is a position on the input character string data, The input character string data can be immediately converted to the corresponding conversion candidate character string data, and if the touch instruction operation position is a position on the conversion candidate character string data, the designated conversion candidate character string The data can be immediately changed to another conversion candidate character string data, and the conversion processing for the input character string and the conversion processing of the conversion candidate character string data can be performed on the display screen displayed on the character string to be processed. It can be executed immediately by a direct instruction operation of the character string display position.
