Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input system for a small electronic device having a display section and a touch input section.

[0002]

2. Description of the Related Art A conventional apparatus is disclosed in Japanese Patent Laid-Open No. 63-14241.
As described in Japanese Patent No. 0, the Kana character input method is performed by the Roman character / kana conversion input by the alphabet key, and only the alphabet is used as the input key, thereby reducing the number of keys.

The above-mentioned prior art is a character input system in which kana characters are input by a combination of consonant and vowel keys of the alphabet keys, and the target character and the character key do not correspond one-to-one. .. In this method, the user must first input a consonant character key and then a vowel character key in order to input one kana character. At this time, the target character is not displayed until the vowel key is pressed. Therefore, there is a problem in that it is inconvenient to input characters because the characters to be input cannot be visually confirmed.

The object of the present invention is, within a limited display range,
The object is to solve the above problems by a character input method of inputting all characters.

[0005]

[Means for Solving the Problems] In order to achieve the above object, characters that can be input are displayed on the screen, characters that are not displayed are displayed by a selection key, and the character to be input is confirmed and selected on the screen. , The character input method that can be input.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of an electronic equipment device showing an embodiment of the present invention.

The LCD display unit 1 displays an application program,
And a display screen used for keyboard display. Keyboard display is performed only when necessary, and normally an application program can use the entire LCD display unit 1 for display. The touch input unit 2 is a transparent touch panel that is pasted on the entire screen of the LCD display unit 1, detects the touch of the user's finger, and when the keyboard is displayed, the key code of the touched key and the keyboard are displayed. If not, the coordinate value of the touched screen is passed to the application program. The keyboard function calling key unit 3 is a plurality of mechanical keys, and by pressing these keys, the keyboard can be displayed on the LCD display unit 1 or erased.

The keyboard function call key unit 3 is composed of the following keys.

1. Alphabet keyboard call key 9 It is a key to call an alphabet keyboard.

2. Number / symbol keyboard call key 10 A key for calling a number / symbol keyboard.

3. Kana keyboard call key 11 This is a key for calling the Kana keyboard.

4. Keyboard erase key 12 This is a key for erasing each keyboard.

5. Kanji mode setting panel call key 13 This is a key for calling the Kanji mode setting panel.

6. Non-conversion key 14 and conversion key 15 are keys used for kana-kanji conversion.

7. Backward key 16, space key 17, tab key 19 These keys are used to input the backward code, space code, and tab code.

8. Up arrow key 23, Down arrow key 22, Left arrow key 18, Right arrow key 20 These keys move the cursor up, down, left and right.

9. Character string input key 21 This is a key for inputting a character string into the application program.

FIG. 1 shows a case where the kana keyboard is displayed by pressing the kana keyboard call key 11, and an input character string display portion 4 and a keyboard display portion 5 are displayed. In the case of a kana keyboard, the keyboard display unit 5 is divided into a line selection unit 6, a daku / semi-dakuten / lowercase selection unit 8 and a character selection unit 7. In the case of an alphabetic keyboard or a numeric / symbol keyboard, the entire keyboard display section 5 serves as the character selection section 7.

The input character string display section 4 displays the character selected by touching the character selection section 7. The character string displayed on the input character string display unit 4 is input to the application program by pressing the character string input key 21 of the keyboard function call key unit 3. The input character string display unit 4 is also used to display the converted kanji / kana mixed sentence during kana-kanji conversion.

FIG. 2 is a plan view of the Kana keyboard, which is displayed by pressing the Kana keyboard call key 11. By continuously pressing this call key,
The hiragana keyboard and katakana keyboard of (a) and (b) are displayed alternately.

FIG. 3 is a plan view of the alphabetic keyboard, which is displayed by pressing the alphabetic keyboard call key 9.
By continuously pressing this call key, (a) in FIG.
The uppercase and lowercase keyboards in (b) are displayed alternately.

FIG. 4 is a plan view of the numeral / symbol keyboard, which is displayed by pressing the numeral / symbol keyboard call key 10. By continuously pressing this call key,
The numeric keyboard and the symbol keyboard shown in FIGS. 4A and 4B are displayed alternately.

A procedure for inputting characters using these keyboards will be described.

FIG. 5 is an explanatory diagram of a hiragana input procedure. For example, when inputting "ki", touch "ka" in the row selection section "Akasata Hayarayawa". Then, "Kakikuke" is displayed in the character selection area, so "Ki" is touched. As a result, "ki" is input.

FIG. 6 is an explanatory diagram of the procedure for inputting a dull sound. For example, when inputting "gu", touch "" in the muddy / semi-voiced / small letter selection section. Then, “Gagugugego” is displayed in the character selection area, so touch “Gugu”. As a result, "gu" is input.

FIG. 7 is an explanatory diagram of a semi-voiced sound input procedure. For example, when inputting "Pi", touch "o" in the daku / semi-dakuon / lowercase selection section. Then, "PapiPupepo" is displayed in the character selection area, so touch "Pi". As a result, "pi" is input.

FIG. 8 is an explanatory diagram of a lowercase letter input procedure. For example, when inputting "yu", touch "small" in the daku / semi-daku / small letter selection section. Then "yayuyo" is displayed in the character selection area, so touch "yu". As a result, "yu" is input.

The katakana input is performed by using the katakana keyboard in the same manner as the above hiragana input method.

With respect to an alphabetic keyboard and a numeric / symbol keyboard, touching a displayed character will input that character.

As described above, according to this embodiment, all the characters can be input within the limited keyboard display portion, and the character to be input is always displayed on the screen, and the user can visually check the character to input, Since it can be input, there is an effect that the operation is easy.
