Abstract
In a portable telephone, when the portable telephone is used for telephone on-vehicle use, the content of displaying is easy to recognize because character size to be displayed is capable of enlarging voluntarily. An input circuit is interfaced with an on-vehicle equipment (not illustrated). An on-vehicle connection detecting circuit detects connection to the on-vehicle equipment, thus outputting on-vehicle detection signal. A selection control circuit outputs an enlargement instruction signal instructing whether it allows normal size of character used on portable condition to display or it allows enlarged size of character to display after receiving an on-vehicle detection signal, and outputting displaying control signal after receiving a hook detection signal. A character storage circuit outputs stored character data after receiving the enlargement instruction signal or the displaying control signal. A displaying control circuit outputs a displaying signal after receiving the character data. An indicator displays characters by virtue of the displaying signal. A hook detection circuit outputs a hook detection signal after judging whether or not the portable telephone is fastened.
