PROBLEM TO BE SOLVED: To provide a portable information terminal device with which an operator can input a password having a privacy function and certainly verify that the input character information is correct. SOLUTION: A displayed character changing block 124 displays the input character without changing on a display 130 when the character is input into a character inputting means 100. Then, after displaying in this manner, the displayed character changing block 124 resets the counter in a timer means 125 and inputs a next character. After the character changing block 124 completes the input of the last character in this way and the timer means 125 times up, the character changing block 124 replaces the last displayed character (i.e. unchanging displayed character) with a mark ('*') representing the character that is masked. Since the timer count value set into the timer means 125 in this condition is a minimum period when the operator can judge whether the character input by the operator with the portable information terminal device is correct, the operator can certainly verify the input password. |
