FIG. 10 shows an example of such a conventional wireless communication device. The wireless communication device 1 includes a display unit 2 and a key unit 3. The one shown in the figure is for Japanese phonetic characters, and these coded data can be input from the key unit 3. Hereinafter, the procedure for inputting the name “Suzuki” will be described with reference to the flowchart shown in FIG.

First, a message input mode is set, and in step 101, for example, "3" is input from the key unit 3. Next, at step 102, it is determined whether or not the mode is the message input mode. If the determination is YES, the process proceeds to step 103, where the key input numeral "3" is displayed on the display unit 2. In the following step 104, it is determined whether or not the input signal is a valid signal. In the case of YES, the process proceeds to step 105, and it is determined whether or not the signal is a row signal. In the case of the row signal, "A" of the stage corresponding to "3" is displayed on the display unit 2 in step 106.

Then, when "3" is input from the key unit 3,
In step 107, it is determined whether or not the signal is a column signal. If YES, the column is lowered by one in step 108, and "a", which is the second row, is displayed on the display unit 2. Furthermore, "3" of the key part 3
Is input, the process proceeds to steps 109 and 110 to determine one character, and "S" is displayed.

[0005] Then, in order to determine the character of "S" in the display, the user presses the "memory" key of the key unit 3 to determine one character in step 110,
Returning to step 103 again, the next character "Z" is input. The input method of “Z” is to press the “3333” and “#” keys, use the “#” key to determine the character with “゛”,
In the same way, the character is determined by the "222" and "MEMORY" keys.

If the signal is not a character determination signal in step 109, the flow advances to step 111 to determine whether or not the signal is an end signal.
In the case of YES, the character is stored by pressing a key indicating the end in step 112, and the process exits the message input mode. On the other hand, in step 111, N
In the case of O, the process returns to step 104 to continue the input operation.
