ABSTRACT:
A portable radio information terminal is provided with an unprocessed-signal detecting circuit for detecting unprocessed upward or downward scroll command signals generated by a rotary input device, a screen moving-down circuit for moving down a displayed screen by as many lines as unprocessed downward scroll command signals detected by the unprocessed-signal detecting circuit, a screen moving-up circuit for moving up a displayed screen by as many lines as unprocessed upward scroll command signals detected by the unprocessed-signal detecting circuit and a display control circuit for counting the number of unprocessed downward or upward scroll command signals detected by the unprocessed-signal detecting circuit and for driving the screen moving-down circuit in the case of unprocessed downward scroll command signals or the screen moving-up circuit in the case of unprocessed upward scroll command signals.
