DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone capable of displaying information such as the name of a call destination on a display unit, and more particularly to a portable telephone suitable for facilitating character input.

[0002]

2. Description of the Related Art A conventional portable telephone has a large number of character input modes for inputting information such as a name of a call destination, and moreover, these are cyclically selected. In addition, the selection of a cloud point and a semi-voice point is alternately selected by a toggle.

[0003]

In a conventional portable telephone, the character input mode is divided into finely divided modes such as full-width kanji, full-width kana, half-width kana, full-width alphanumeric, half-width alphanumeric, full-width symbol, and half-width symbol. Was set to cyclic. To select the desired mode among these, it is necessary to push the button and send the mode in one direction in order, especially if you try to select the previous mode, you have to turn around and press the button The number was increasing. Conventionally, the mode changes each time the button is pressed in this order from full-width kanji, as in the above example, and returns to full-width kanji after the symbol half-width. Therefore, for example, when changing from a half-width alphanumeric character to a full-width alphanumeric character, it is necessary to press the full-width symbol, half-width symbol, full-width kanji, full-width kana, half-width kana and full-width alphanumeric buttons six times.

[0004] In addition, a cloud button and a semi-voice point in the row of “ha” are shared by a single button.
It had a toggle that alternated with the half-dull point. In other words, each time the button was pressed, the line changed to the "ba" line and the "@" line.
In the prior art, when inputting characters with a semi-voiced point or a clouded point consecutively to the characters of the "ha" line, for example, when inputting "papa", first select and input "c" with the cursor, and then input the character. Press the button. At this time, if the voiced / semi-voiced button button is in the semi-voiced voice mode, the first "PA" is input by pressing the button. Next, select "C" again with the cursor and enter it, and press the button for "Dakuten / Semi-Dakuten". At this time, the button of the voiced / semi-voiced voice is in the voiced voice mode by the toggle, and when the button is pressed, “V” is input. Therefore, to input the next “PA”, delete this “BA”, select and input “C” again with the cursor, and press the button of the voiced / semi-voiced point. As a result, the next “PA” is input. For this reason, the number of times the button is pressed has been increased in the case of continuously inputting a character having a semi-voiced voice or a character having a voiced-voiced dot.

When the input mode is kana mode, the uppercase mode, lowercase mode, full-width mode or half-width mode can be selected as the submode. When is in the alphanumeric mode, uppercase mode or lowercase mode and full-width mode or half-width mode can be selected as sub-modes. When the input mode is symbol mode, full-width mode or half-width mode can be selected as sub-mode. In the present embodiment, the selection of the sub mode is performed by the input keys of the dial cursor unit 70b. When selecting the uppercase mode or the lowercase mode, a rectangle is displayed at the position of the numeral “9” on the display unit 50, and the display changes alternately between the uppercase mode and the lowercase mode each time the input key of the numeral “9” is pressed. I do. When the current mode is the uppercase mode, the character “small” is displayed at the position of the numeral “9” on the right side of the rectangle to indicate that there is a lowercase mode as a mode that can be selected from this state. Such display is performed when the graphic display mode is D, E, H, or J. On the other hand, when the current mode is the lowercase mode, the number “9” is displayed.
At the right side of the rectangle, the character "large" is displayed on the right side of the rectangle indicating that there is a capital mode as a mode that can be selected from this state. When the full-width mode or the half-width mode is selected, a rectangle is displayed at the position of the number “3” on the display unit 50, and the display changes alternately to the full-width mode and the half-width mode each time the input key of the number “3” is pressed. I do. When the current mode is the full-width mode, the character "half" indicating that there is a half-width mode as a mode selectable from this state is displayed on the right side of the rectangle at the position of the numeral "3". On the other hand, when the current mode is the half-width mode, the character “all” indicating that there is a full-width mode as a mode selectable from this state is displayed on the right side of the rectangle at the position of the numeral “3”. Such display is performed when the graphic display mode is F, G, H, I, or J.

An example of a character input method according to the present embodiment will be described below. In the case of the kanji mode, as shown in FIG. 14, the control means 60 controls a plurality of characters (in this case, “Ai-okakikukeko”) to be selected on the display unit 50 and the plurality of characters. Is displayed (in this case, a black rectangle in which the character is displayed in black and white inverted at the position of the character "A"). At the same time, a graphic indicating the position of the input key associated with the input operation of the character selected by the cursor, that is, a graphic in the graphic mode E is displayed. In this case, by default, the sub mode is set to the upper case mode, and the small mode is selected on the right side of the rectangle at the position of the numeral “9” of the graphic in the graphic mode E to indicate that there is a small mode as a mode that can be selected from this state. Characters are displayed.

To select a character from this state, press the "2" key or the "8" key of the dial cursor key section 70b to select the character line to be selected ("a" line, "ka" line, "sa" line).
Line). When the "8" key is pressed, the range displayed on the display unit 50 in the character table (portion surrounded by a dotted line in the figure, hereinafter referred to as display range) moves downward in the figure as shown in FIG. I do. When the "2" key is pressed, the display range moves upward in the figure. In FIG. 6 (a), two lines, a "ka" line and a "sa" line, are displayed in the display range, and a cursor is displayed on the upper line (in this case, the "ka" line) of the two lines.
The cursor moves left or right in the figure by pressing the "4" key or "6" key of the dial cursor key section 70b, respectively. For example, to select “ku”, the cursor is moved to “ku” and the “5” key is pressed to confirm the selection, and the selection is displayed in parentheses displayed above the display range in FIG. In FIG. 6 (a), the cursor is moved to the right. When the cursor exceeds "", the display range is automatically shifted downward, and the cursor is automatically moved to "".
Conversely, if you move the cursor from “ku” to the left,
Is exceeded, the display range is automatically shifted upward, and the cursor automatically moves to “O”. When the characters displayed in parentheses are converted to kanji, they are converted by pressing the soft key "2" 702, and then, by pressing the down movement key 704 or the soft key "2" 702, conversion candidates are displayed in parentheses. Is done. When the desired conversion candidate is displayed, it is determined by pressing the soft key "3", and is displayed in the determined character area above the parentheses.

At this time, since the figure indicating the position of the input key differs depending on the character, the corresponding figure is displayed in the flowchart shown in FIG. That is, "2", "4",
When either the "6" or "8" key is pressed (step 401), the character table display start position (display range) moves (step 402), and a graphic number is obtained from the graphic management table (step 403). After displaying the character table (step 404), a graphic display process is performed using the graphic number (step 405). FIG. 8 shows an example of a step of performing a graphic display process based on a graphic number. FIG. 5 shows a character table and a graphic management table for Hiragana. A similar character table and graphic management table are also stored in the storage area 85 for katakana. In the case of katakana, since full-width and half-width modes also exist, 6 to 10 are set corresponding to data 1 to 5 in FIG. FIG. 9 shows an example of a graphic displayed on the display unit 50. Numerical data 6 is in graphic mode F, numerical data 7 is in graphic mode G, numerical data 8 is in graphic mode H, numerical data 9 is in graphic mode I,
The numerical data 10 corresponds to the graphic mode J, respectively.

In FIG. 8, when it is determined that a capital letter Hiragana has been input (step 501), steps 511-5 are determined.
Numerical data for the character entered in 15 is determined,
Graphic displays A to E are performed corresponding to the respective numerical data (steps 521 to 525). If it is determined in step 501 that the character is not an uppercase hiragana, it is determined whether the character is a full-width katakana (step 601). If it is determined in step 601 that double-byte uppercase katakana has been input, numerical data for the input character is determined in steps 611 to 615, and graphic displays F to J are performed corresponding to the respective numerical data (steps 621 to 621). 62
5). If it is determined in step 601 that the character is not a double-byte uppercase katakana, the process proceeds to the next step.

Next, the processing procedure of full-width and half-width conversion is shown in FIG.
This will be described with reference to FIG. When the "3" key is pressed in FIG. 10 (step 701), the input mode is determined to determine the conversion that can be performed in this mode (step 702), and the graphic number is obtained from the graphic management table (step 703).

If it is determined in step 911 that the mode is the uppercase hiragana mode, the mode that can be converted in this mode is the lowercase hiragana input mode, and a graphic in the graphic mode D or E (the lowercase is indicated) is displayed on the display unit 50 (step 921). . Here, if the "9" key is further pressed (Y), the input mode becomes the lowercase hiragana mode (step 931), and if the "9" key is not pressed (N), the input mode remains the uppercase hiragana mode. If step 911 is No, the process proceeds to step 912. If it is determined in step 912 that the mode is the lowercase hiragana mode, the only mode that can be converted in this mode is the uppercase hiragana input mode. Is displayed (step 92).
2). Here, when the “9” key is further depressed (Y), the input mode becomes the uppercase hiragana mode (step 9).
32) If the "9" key is not pressed (N), the input mode remains in the lowercase hiragana mode. Step 912
Is No, the process proceeds to step 913, and step 91 is executed.
If it is determined in step 3 that the mode is a full-width katakana mode, the only mode that can be converted in this mode is the full-width lower-case katakana input mode, and a graphic in graphic mode I or J (the lower case is indicated) is displayed on the display unit 50 (step 92).
3). Here, if the “9” key is further pressed (Y), the input mode is changed to the full-width lowercase katakana mode (step 933), and if the “9” key is not pressed (N), the input mode remains the full-width uppercase katakana mode. Become. If No in step 913, the process proceeds to step 914. If it is determined in step 914 that the mode is the full-width lowercase katakana mode, the only mode that can be converted in this mode is the full-width uppercase katakana input mode. Is displayed (step 924).
Here, when the "9" key is further pressed (Y), the input mode is changed to the full-width katakana mode (step 93).
4) If the "9" key is not pressed (N), the input mode remains the full-width lowercase katakana mode. Step 91
When No. 4 is No, the process proceeds to Step 915, and Step 9
If it is determined in step 15 that the character is in the half-size uppercase katakana mode, the mode that can be converted in this mode is the half-size lowercase katakana input mode, and a graphic in the graphic mode H or J (the lowercase is indicated) is displayed on the display unit 50 (step 92).
5). Here, if the "9" key is further pressed (Y), the input mode is set to the half-width lowercase katakana mode (step 935), and if the "9" key is not pressed (N), the input mode remains the half-width uppercase katakana mode. Become. If No in step 915, the process proceeds to step 916. If it is determined in step 916 that the character is in the single-byte lowercase katakana mode, the only mode that can be converted in this mode is the single-byte uppercase katakana input mode. Is displayed (step 926).
Here, when the “9” key is further pressed (Y), the input mode is changed to the half-width uppercase katakana mode (step 93).

Therefore, the number of times the button is pressed can be reduced even when a character having a semi-voiced voice or a character having a voicedly voiced character is continuously input. Similarly, the number of times the button is pressed can be reduced even when the character of the voiced dot and the character of the semi-voiced character are alternately input.

When a plurality of candidate characters to be selected are the Japanese syllabary "ta" line, the control means 60 displays the input key assigned to the voiced dot on the display unit, and displays the character ""
Is displayed on the display unit 5
Control is performed so as to be displayed at 0. Specifically, graphic modes B and D are prepared for the “ta” line,
Graphic mode B is displayed for "ta", "chi", "te", and "to", and graphic mode D is displayed for "tsu". In the case of the graphic mode B, in addition to the five rectangles of the mode A, an input key corresponding to the number “7” is shown as an input key of a voiced dot. After selecting one of the characters with the cursor, the user presses the input key “7”,
When the character is confirmed with the input key "5", a character with a clouded point is input. The graphic mode D is displayed for the character "tsu", and the mode A is displayed for the graphic mode D.
In addition to the above five rectangles, as shown in FIG. 17, the input key corresponding to the number “7” is shown as an input key of a voiced dot, and the input key corresponding to the number “9” is shown as an input key of a small letter. . If you select the letter "", enter it in uppercase mode if it is in uppercase, or enter it in lowercase mode by operating the input key "9" assigned to lowercase if it is in lowercase, and enter it with a cloud mark If so, by operating the input key "7" assigned to the voiced dot, the character with the voiced dot is directly input. Also in this case, the number of key operations is small, and the character input operation is facilitated.

The character string input and confirmed as described above can be pasted to another portion by the copy / paste function. To use this mode, first, the function key 744 is pressed to enter the copy / paste mode, the soft key “1” 701 is pressed to display the start point input screen, and then the up key 702, the down key 704,
The cursor is moved to the start point using the right movement key 705 and the left movement key 706, and the soft key “1” 701 is pressed to determine the start point. When the start point is determined, the screen automatically changes to the end point determination screen.
