ABSTRACT:
There is provided a portable terminal device which is capable of transmitting and receiving data such as an image during a voice call by using a radio communications system allowing parallel access.The portable access allows parallel access where a voice call by way of a circuit switching system and data communications using a packet communications system are made in parallel. In case an instruction to transmit data to a distant party is issued by way of an operation on the key operation section during a voice call (S16), the directory data is referenced and the mail address of the distant party is retrieved and acquired (step S21). An electronic mail with the photo image data, etc. shot with a camera section attached is automatically generated and transmitted to the distant party by way of packet communications (S23). In case the received electronic mail is from the distant party and image data, etc. is attached, the receiving party opens the data and displays the data on the display section on a priority basis.
