As an example of the disclosure, for example, each time the "A" key is pressed on the display unit, “A” → “I” → “U” ... is displayed. For example, in order to input “O”, it is necessary to press the “A” key five times. If the characters on the same line are continuous, enter "O" once, move the cursor to the right with the cursor key, and then repeat "O".
Need to be entered, resulting in 11
It can also be turned.

As a technique for solving this problem, there is a key for designating an alphabetic character group, a katakana character group, etc. For example, after pressing a key for designating a katakana character group, If you want to specify "to" when ", and" is displayed on the display, press the numeric keypad to select "5".
Enter. If you want to convert this specified character into Kanji, press the key for specifying the Kanji group to specify the Kanji group corresponding to the character "to" (for example, the Kanji group with "to" as the first reading). The numbers are displayed on the display. From this state, the ten keys are used to input the numbers from the beginning of the kanji group displayed on the display unit to select the desired kanji. For example, when the kanji to be designated is “east” and the kanji “east” is displayed at the 6th position from the beginning, “6” is input from the ten keys.

A technique for reducing the number of key inputs is disclosed in Japanese Patent Laid-Open No. 4-129360.

As another technique for reducing the number of key inputs, the characters from the "A" line to the "Wa" line are associated with "0" to "9" and any character on any line is input. At this time, if a specific number key from “0” to “9” is pressed and, for example, a line “A” is selected in the display area while pressing the specific number key, “A” is displayed. → "I" →
"U"->"E"->"O"->"A" ... is displayed in sequence, and the characters displayed at the moment when the pressed key is released,
For example, there is disclosed a technique in which the character "U" is fixed when the display is "A" → "I" → "U" at the moment when the display is released (Japanese Patent Application No. 2000-124707).

Next, a conventional example of character input in a conventional cordless telephone will be described with reference to the drawings.
