ABSTRACT:
A portable phone having a recording function to which this invention is applicable comprises a plurality of memories, a switching unit, and a reproducing unit. Each of the memories is used for endless-recording, as a conversation content audio data during the telephone conversation. The switching unit can switch the memories from a first memory of the memories to a second memory of the memories so that the second memory endless-records the audio data instead of the first memory which endless-records, as the conversation content, the audio data until then. The reproducing unit is used for reproducing the conversation content that the first memory endless-records before being switched by the switching unit.
