<p>A portable telephone 30 in which changing of melodies is easy comprises means 37 for storing melody data of incoming call alert sound and a connector 20 which is capable of externally transmitting analog audio signal. The portable telephone further includes means (41, 34) for entering the digital audio data via a photo receiving member 40 which is provided relative to the connector 20 so that the member 40 can receive light and for writing the digital audio data into the storing means 37 as the melody data. Since the melody data is accepted via existing connector as photo signal, it is possible to substantially automatically enter new melody data for rewriting without increasing the number of exterior parts. <IMAGE></p> |
