Abstract

PURPOSE:To facilitate the change of an exhibition form concerning disired letters by installing a means which changes in sequence the exhibition form of the letter data, which corresponds to a detected operational position, according to an operational condition by a discrimination means. CONSTITUTION:A sampling circuit 8 is carying out the cyclic sampling of touch switches one by one all the time. A touch coordinate detector 9 investigates in the first place an on/off condition of the touch switch taken up by the sampling circuit 8. When the touch switch of the sample is on, the coordinate data is outputted to CPU 2. The CPU 2, when either of the modes is set, judges on the basis of the coordinate data from the touch coordinate detector 9 as to how many times the same position (the same letter) is touched in succession. Then, the exhibition form of the letter related to the touch is changed according to the number of touch times and the mode set.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a word processor, that is, a data display device such as a document preparation device.

[0002]

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

[0003]

Therefore, in order to add an accent to a created document or to emphasize a part of the document, the character size of some characters in the document is doubled, an underline is drawn, etc. When changing the expression form partially, for example, use the function keys to instruct the content of the expression form change, move the cursor to the beginning of the character string to be changed using the cursor movement keys, and confirm the beginning with the specified function key. After that, the key operation was troublesome, such as moving the cursor to the tail of the character string to be changed with the cursor movement key again and confirming and executing the tail with a predetermined function key. In addition, since the character string to be changed is specified by operating the cursor movement key, it is easy to make a specification error. An object of the present invention is to make it possible to easily change the expression form relating to a desired character.

[0004]

The means of the present invention are as follows. Display means for displaying character data on the display portion, point contact operation for this display portion, and detection means for detecting the operation position thereof, and operation state for the same position of the point contact operation detected by this detection means are determined. And a changing means for sequentially changing the expression form of the character data corresponding to the operation position detected by the detecting means according to the operation state of the judging means.

[0005]

[Operation] The operation of the means of the present invention is as follows. It is assumed that a character displayed on the display unit is displayed in a normal expression form, that is, a display form that is not combined with a halftone dot pattern or the like. In this state, when it is desired to add a special expression form to the character, for example, a shaded pattern or an underline, the display position on the display unit where the character is displayed is touched with a finger or the like. Then, the point contact operation is detected by the detection means, and the expression form of the character is changed by the first operation, for example, in the form of addition of a mesh. In this expression form, the point contact operation state with respect to the same position, for example, the operation time of continuous operation, the number of times of operations, etc. is discriminated by the discriminating means, and the changed representation form is further changed according to the operation state, For example, it is displayed in an expression form such as underline. Therefore, the expression form for a desired character can be changed by an extremely simple operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS.

Configuration FIG. 1 is a configuration diagram of a document creation apparatus according to an embodiment. This document creation apparatus refers to the conversion dictionary 3 under the control of the CPU 2 for the character data input from the key input unit 1, performs various processes such as Kana-Kanji conversion, and outputs the processing results and the like to the 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 an expansion key 1B and a reduction key 1 in addition to the kana character key 1A for inputting kana character data.
It has a C key, a modifier key 1D, and a release key 1E.

The enlargement key 1B and the reduction key 1C are keys for setting the enlargement mode for enlarging the character size and the reduction mode for reduction, respectively, and the modifier key 1D is
This key is used to set a modifier mode for adding underlining and shading to a character, and for making a character bold. The mode information set by these keys is
It is stored in the mode register r. The cancel key 1E is a key for canceling the setting of each of the above modes, and when the cancel key 1E is operated, the contents of the mode register r are cleared.

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

The sampling circuit 8 constantly samples one touch switch cyclically at a time.
The touch coordinate detection 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, when any one of the above modes is set, the CPU 2 determines, based on the coordinate data from the touch coordinate detection unit 9, how many times the same position (the same character) is touched successively. Then, the expression form of the character relating to the touch is changed according to the number of touches and the set mode. For example, in the enlargement mode, when a character with a full-size character is touched twice in succession, the full-size character is triple-doubled. In such processing,
The size number register n or the modified form number register m is used.

[0012] Operation Next, the operation with reference to FIGS. 2-7.
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 touch coordinate detection unit 9 detects the coordinate of the touch switch related to the ON and transfers the coordinate data to the CPU 2 (step S1 in FIG. 2). Then, the CPU 2 specifies the character data in the document memory 4 corresponding to the touch coordinates (step S2). Next, it is determined whether or not the mode information is stored in the mode register r (step S
3) If it is not set, the process is terminated as it is, and if it is set, the content of the mode is determined (step S4). Then, the processing according to the mode is performed.

When the enlargement mode is set by operating the enlargement key 1B, it is judged whether or not the character size of another character has been enlarged immediately before (step S5). , Store the character size number of the touched character in the size number register n (step S
6) The content of the size No. register n is incremented by "1" (step S7). It should be noted that FIG. 3 shows the character size numbers in the enlargement mode and the reduction mode and the magnifications corresponding to the numbers.

When the processing of step S7 is completed, or when it is determined in step S5 that the character size of another character has been enlarged immediately before, the process proceeds to step S8, and the document memory 4 corresponding to the touched character. The character size data for the character data in is changed based on the current contents of the size number register n. Then, the character size of the touch character on the display screen is changed according to the changed character size (step S9). And at the same position,
That is, it is determined whether the same character is touched (step S10), and when the same character is touched, the process returns to step S7. On the other hand, if the same character is not touched, it is determined that the character size has been determined, and the process ends.

The processes of steps S5 to S10 described above will be described with a specific example. In order to emphasize “ski” in the “ski tour notice” displayed in full-width in FIG. 4 (a), as shown in FIG. If it is desired to change to, as shown in FIG. 5, the enlargement mode is set and each character of "su", "ki", and "-" can be continuously touched once. That is, when the “su” is touched once, since the character size of another character has not been enlarged or changed immediately before, the process proceeds to step S6 via step S5, and is the character size of the touched “su”. Full-width character size No. "1"
Is stored in the size No. register n. Then, it is incremented to "2" in step S7 (see FIG. 5), and in step S8 and 9 respectively, the document memory 4,
It is changed to double size (see Fig. 3) corresponding to the character size No. "2" on the display screen. Then, when the next "ki" is touched just by touching "su" once, step S1
At 0, it is determined that the same character is not touched, and the process ends. Then, the process returns to step S1 again.

At this time, since the “s” has been enlarged immediately before, the process immediately proceeds to step S8 via step S5.
Proceed to. As a result, the contents of size No. register n is "2" corresponding to double-width at the moment,
"Ki" can be changed to double size just like "Su" with just one touch. "-" Can be changed to double angle with one touch in the same route as "Ki". Therefore, the operation becomes simple.

When the modifier mode is set by operating the modifier key 1D, it is determined immediately before whether another character is modified (step S11). As a result, if another character was desired to be modified immediately before, the modification form No. of the touched character is changed to the modification form N.
o. Store in register m (step S12) and modify form N
o. The content of the register m is incremented by "1" (step S13).

Incidentally, FIG. 6 shows the modification form No. and the type of modification corresponding to the No. When the process of step S13 is completed, or when it is determined in step S11 that another character has been modified immediately before, step S1
4, the modification data corresponding to the character data in the document memory 4 corresponding to the touch character is changed based on the current contents of the modification mode number register m. Then, the modified form of the touch character on the display screen is changed to the modified modified form N.
Change according to o. (step S15). Then, it is determined whether the same position, that is, the same character is touched (step S16). When the same character is touched, the process returns to step S13. On the other hand, when the same character is not touched, it is determined that the modified form has been determined, and the process ends.

The processing of steps S11 to S16 described above will be described with a specific example. When it is desired to shade and underline the “ski resort” and the “schedule” displayed as shown in FIG. 4A, as shown in FIG.
As shown in, "s" three times, "ki", "-",
It is sufficient to touch each of the "fields" one by one, and then touch the "day" three times and then the "step" once.

That is, when "S" is touched once, since another character is not modified immediately before, the process proceeds to step S12 via step S11,
As the modification form number for the touched “s”, “0” indicating no modification is stored in the modification form number register m. Then, it is incremented to "1" in step S14, and in steps S15 and 16, the underline corresponding to the modified form No. "1" on the document memory 4 and the display screen is the touch-related "s". Is added to. This underline displayed is not what you want, so if you touch "Su" one more time,
The process returns to step S13 via step S16, and the content of the modification mode number register m is updated to "2".

Then, the “s” related to the touch is changed to a bold type on the document memory 4 and the display screen in correspondence with the modification form No. “2”. I don't want this bold type, so
When "S" is touched once more, the content of the modified form number register m is updated to "3", and the "S" touched three times in succession is displayed on the document memory 4 and the display screen.
Shading corresponding to the modified form No. “3” is applied.

Since this shading is a desired modification mode, when "Ki" is next touched, at this time, since "S" has been modified immediately before, step S1 is performed.
The process directly proceeds from step 1 to step S13. As a result, the modified form
Since the contents of No. register m remains "3",
"Ki" is shaded just like "Su" by touching it once. In the case of "-" and "field," as in the case of "ki," the screen is shaded with one touch.

Next, when "day" is touched once, the screen is shaded as in the case of "ki", "-", and "place" described above. However, I want to underline this "day", so if I touch "day" again, the contents of the modified form number register m will be changed in step S13.
It is changed from "3" to "0". That is, step S
The increment process in 13 is 0 → 1 → 2 → 3 → 0 →
It is performed cyclically like 1 → ……. The same thing can be said for the increment process in step S7 in the enlargement mode.

No modification is made in this modification form No. "0", so if the "day" is touched once again, the contents of the modification form No. register m are updated to "1", and , The desired underline is drawn.
Then, when the next "touch" is touched once, as described above, the process immediately proceeds to step S13 via step S11. Get burned.

When the reduction mode is set, the reduction process is performed at the reduction ratio according to the character size No. under the reduction mode shown in FIG. 3 by the same processing as steps S5 to S10. (Step S17).

As described above, the transparent touch panel 5A capable of directly designating the processing object itself allows not only the designation of the processing object but also the type of modification of the expression form to be easily changed. ..

The present invention is not limited to the above-described embodiment, and for example, without providing a mode setting key such as the enlargement key 1B, the half-width, the double-width, the underline, and the half-width can be determined only by the number of touches on the transparent touch panel 5A. You may make it specify a call etc. It is also possible to simultaneously specify a plurality of expression forms in accordance with the number of touches, for example, when touching twice, double-width and adding an underline.
