DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device capable of additionally specifying a character attribute for a character displayed on a display screen.

[0002]

SUMMARY OF THE INVENTION According to the present invention, in a document creating apparatus, a transparent touch panel is provided on a display screen of a display means, and character data touched by the transparent touch panel is specified with an underline or a shaded pattern. By adding an attribute such as, the attribute can be quickly added.

[0003]

2. Description of the Related Art Conventionally, in a document creation apparatus, in order to reduce the complexity of key operations, when inputting document information, the cursor is automatically shifted right by one character each time one character is input. When inputting characters continuously,
The configuration is such that it is not necessary to operate the cursor shift key every time one character is input.

[0004]

However, there are the following problems when adding attributes such as underlining and shading. For example, if you want to add an underline to “Popular products word processor XY for sale at a low price. After entering“ Outside 1 ”, to emphasize“ Popular products ”and“ Cheap ”, The following operations were performed. Note that “outside 1” in the above example sentence indicates a cursor. That is, the cursor located at the next digit of the reading point "." At that time is shifted to the position of "person" by pressing the cursor shift key 21 times, for example,
While holding down the function key, double-function 1
For example, by pressing a predetermined key to which the underline function is assigned four times, an underline is added like “ popular product ”. Then, after releasing the press of the function key, the cursor shift key is pressed nine times to shift the cursor to the position of "case", and further, the predetermined key is pressed twice while the function key is kept pressed. Adds an underline like " cheap ". Then, when it is desired to start character input again from the next digit of the above reading ".", Further release the function key and then press the cursor shift key seven times, as in "outer 2". , The cursor had to be returned to the next digit after the reading "." As described above, conventionally, adding an attribute requires a very complicated key operation, and it has not been possible to quickly add an attribute. An object of the present invention is to make it possible to quickly add an attribute.

[0005]

The means of the present invention are as follows. While displaying multiple characters on the display screen,
A display means for displaying a cursor for character editing on this display screen, an attribute designating means for designating the addition of a character attribute to the character, and an instruction operation for an arbitrary display position on the display screen on which each character is displayed. Detecting means for detecting, and when an instruction operation of a display position is detected by the detecting means after addition designation of a character attribute by the attribute designating means, a character at a character position corresponding to the display position at which the instruction operation is performed is displayed. When a character position is added to the display position by the detection means in a state where the character attribute is not added and the character attribute is not specified, the character editing cursor is set at the display position where the instruction operation is performed. And control means for moving.

[0006]

The operation of the means of the present invention is as follows. A plurality of characters are displayed on the display screen and a cursor for character editing is displayed. When an instruction operation of the display position is detected on the display screen after the designation of the addition of the character attribute by the attribute designation means, the character attribute is added to the character at the character position corresponding to the display position where the instruction operation is performed. When an operation for indicating a display position is detected in a state where the addition of the character attribute is not specified, the cursor for character editing is moved to the display position where the instruction operation is performed.

FIG. 1 is a functional block diagram of the present invention, showing a schematic diagram of the flow from input means to conversion means.

First Embodiment Hereinafter, an embodiment will be described with reference to FIGS.

[0008] Configuration Figure 2 is a block diagram of a document creating apparatus according to one embodiment. This document creation device performs various processes such as kana-kanji conversion on character data input from the key input unit 1 with reference to the conversion dictionary 3 under the control of the CPU 2, and outputs the processing results and the like to a document. The data is stored in the document memory 4, displayed on the display unit 5, and printed by the printing unit 6.

The key input unit 1 includes a kana character key 1A for inputting kana character data, underline, shading, bold,
It has an attribute key 1B for designating attributes such as double-width, half-width, and enlargement. When an attribute is designated by the attribute key 1B, a value corresponding to the designated attribute is set in the attribute flag 7. The attribute flag 7 is composed of three bits, and if no attribute is specified, all three bits are reset, such as "000". In addition, when a later-described transparent touch panel 5A is touched in a state where an attribute is specified, an attribute related to the specification is added to a character corresponding to a touch position.

The display section 5 has a transparent touch panel 5A and a liquid crystal display section 5B. The transparent touch panel 5A is arranged on a display screen of the liquid crystal display section 5B. This transparent touch panel 5A has a touch switch group formed of a transparent member on a flexible transparent film,
It has a structure arranged in a matrix, and the display contents of the liquid crystal display unit 4B thereunder can be seen.

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 is for designating the position of a cursor displayed on the display screen of the liquid crystal display unit 5B.

FIG. 3 is an external view of a document creating 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, it is easy to specialize in position specification using the transparent touch panel 5A on the left and specialize in data input and attribute specification using the key input unit 1 with the right hand. Of course, using both hands, input data and specify attributes from the key input unit 1,
After that, the character to which the attribute is to be added can be specified by touching the transparent touch panel 5A with the left hand. Further, the housing in which the display unit 5 is formed is configured to be foldable to form a large screen, and is superimposed on the key input unit 1 on the main body side in a state of being folded in two, so that it is compact. It is configured to be easily portable.

[0014] Operation Next, the operation with reference to FIGS.

When the transparent touch panel 5A is touched with a finger or the like, a touch switch located at the touched portion is turned on. Then, the touch coordinate detecting unit 9 detects the coordinates of the touch switch that is turned on, and transfers the coordinate data to the CPU 2 (step S1 in FIG. 4). And C
The PU 2 determines whether or not the attribute is specified by determining whether or not the content of the attribute flag 7 is “000” (Step S2). As a result, if the content of the attribute flag 7 is not “000” and an attribute is specified, the address data of the area on the document memory 4 corresponding to the detected touch coordinates is calculated and stored in the document pointer 10. Then, the character data indicated by the document pointer 10 is specified (step S3). Next, attribute data related to the designation indicated by the attribute flag 7 is added to the specified character data and registered in the document memory 4 (step S4). And
The character corresponding to the touch position is changed and displayed in a form to which an attribute is added (step S5).

In a specific example, when the display state is as shown in FIG. 5 (a), the attribute key 1B for shading is operated, as shown in FIGS. 5 (b) and 5 (c). Then, on the transparent touch panel 5A, the parts "D", "E", and "F" are stroked with a finger, and as shown in FIG.
Shading is performed on “E” and “F”.

As described above, since the attribute can be added by the transparent touch panel 5A capable of directly specifying the position, the attribute can be quickly added.

At this time, as shown in FIG.
The cursor indicated by is not shifted. Therefore, when performing further character input after performing the attribute addition operation, it is not necessary to shift the cursor to the next digit at the end of the sentence, and character input can be resumed immediately (FIG. 5).
(D)). When it is determined in step S2 of FIG. 4 that there is no attribute designation, the cursor is moved so as to designate a position on the display screen of the liquid crystal display unit 5B corresponding to the touch coordinates detected by the touch coordinate detection unit 9. Pointer 11
Is updated (step S6). Next, the cursor is displayed at the position designated by the cursor pointer 11 (step S7), and the document pointer 10 is updated so as to correspond to the currently displayed (moved) cursor position (step S8).

That is, when the user touches the transparent touch panel 5A without specifying the attribute, the cursor is moved to the touch position as shown in FIGS. 4 (e) and 4 (f). Therefore, as shown in FIGS. 5 (e) to 5 (g), when once correcting the input character, the character to be corrected is touched via the transparent touch panel 5A without designating the attribute.
Correction may be input, and correction can be made quickly.

[0020]

According to the present invention, when a character attribute is added to a desired character position on a display screen on which a plurality of characters are displayed, a cursor position for character editing displayed on the display screen at that time is added. The character attribute can be added to the desired character position without moving the character.
Therefore, after the character attribute is added, a character input operation or a character editing operation from the original cursor position can be immediately performed. Further, in the present invention, whether to add a character attribute not accompanied by the cursor movement or only the cursor movement to the display position instructed on the display screen is determined by the presence or absence of the designation of addition of the character attribute. Since the determination is made, it is possible to immediately add the character attribute to the desired display position on the display screen or move the cursor.
