Abstract
A pager has an input unit, a signal generating unit, a conversion unit, a receiving unit and a display unit. The input unit reads information input by handwriting as image data. The signal generating unit generates a DTMF signal from the image data input by the input unit. The conversion unit converts the DTMF signal from the signal generating unit into a DTMF tone, and outputs it to the transmitter of a telephone apparatus. The receiver unit receives the transmitted signal. The display unit displays display data generated according to image data in the signal received by the receiving unit.
