Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cordless telephone and a kana character input method, and more particularly, to a cordless telephone and a kana character input method capable of inputting characters using a parent device and a child device.
[0002]
[Prior art]
Many techniques for character input methods of conventional telephones and mobile phones have been disclosed. For example, each time the “A” key is pressed once on the display unit, “A” → “ ”→” U ”... is displayed. For example, to input“ O ”, it is necessary to press the“ A ”key five times, and“ O ”is the same line. If there is a sequence of characters, it is necessary to move the cursor to the right with the cursor key once after inputting "O", and then input "O" again. As a result, the number of key presses is 11 times. Also become.
[0003]
As a technique for solving this problem, it has a key for designating an alphabet character group, a katakana character group, etc., for example, after pressing a key for designating a katakana character group, `` Ta, Chi, Tsu, Teto '' Is displayed on the display unit, "5" is input from the numeric keypad when it is desired to designate "to". When it is desired to convert the designated character into kanji, the kanji group corresponding to the character “to” (for example, the kanji group having “to” as the first reading) is predetermined by pressing the kanji group designation key. Numbers are displayed on the display. From this state, a desired Chinese character is selected by inputting the number from the top of the Chinese character group displayed on the display using the numeric keypad. For example, when the Chinese character to be designated is “East” and the Chinese character “East” is displayed sixth from the top, “6” is input from the numeric keypad.
[0004]
A technique that reduces the number of key inputs as described above is disclosed in Japanese Patent Laid-Open No. 4-129360.
[0005]
In addition, as another technique for reducing the number of times of key input, the characters from the “a” line to the “wa” line are associated with “0” to “9”, and when inputting an arbitrary character on an arbitrary line, When a specific numeric key is pressed from “0” to “9” and, for example, “A” row is selected in the display area while the specific numeric key is pressed, “A” → “I” ”→” U ”→“ E ”→“ O ”→“ Ah ”... are displayed in order, and characters displayed at the moment when the pressed key is released, for example,“ A ”→“ I ” A technique is disclosed in which the character “U” is confirmed when released at the moment when “→” is displayed (Japanese Patent Application No. 2000-124707).
[0006]
Next, a conventional example of character input in a conventional cordless telephone will be described with reference to the drawings.
[0007]
FIG. 9 shows an example of a conventional cordless telephone, (A) shows its parent device, (B) shows its child device, and FIG. 10 shows the storage state of kana characters in the ROM of the cordless phone child device shown in FIG. FIGS. 11 and 11 are front views showing a state of key arrangement in the cordless phone of the cordless telephone shown in FIG.
[0008]
The cordless telephone of this conventional example shows the contents disclosed in Japanese Patent Application Laid-Open No. 2000-59484. When the phone book registration information is searched using the key group 170 of the handset 150, the operation state of the shift key 171 and the shuttle key 173 Accordingly, the kana characters are searched in the vowel or consonant direction in ascending or descending order, and the shuttle key 173 is set to the neutral state with the desired kana characters displayed on the LCD 155. If the shuttle key 173 is pressed once in this state, the kana characters currently displayed on the LCD 55 are registered as initials at the time of starting the search when searching for the phone book registration information thereafter. For example, if the shuttle key 173 is displayed in the neutral state with the kana character “t” displayed on the LCD 155 and a push-in operation is performed only once, then the phone book registration information is obtained by swinging the shuttle key 173 up and down. In the search, “t” is fixed as an initial letter at the start of the search. As a result, for example, in the case of searching for and reading a telephone number registered with the address “Tokio Ichiro”, the purpose is much faster than when searching for phone book registration information in ascending order or descending order in the order of Iueo. Can be searched.
[0009]
Similarly, when the shuttle key 173 is set to the neutral state while the desired kana character is displayed on the LCD 155 and the shuttle key 173 is pressed twice in this state, the kana character currently displayed on the LCD 155 is changed to the phone book. It is confirmed as an input character when registering. Therefore, by repeating the above-described processing, for example, the input of the address at the time of telephone book registration such as “Tokotataro” can be executed by one-hand operation of the shift key 171 and the shuttle key 173.
[0010]
