PROBLEM TO BE SOLVED: To provide a portable telephone system capable of simple data communication without necessitating an additional adapter outside. SOLUTION: A display part 5 uses a display element of a so-called dot type and is capable of drawing a still picture by the key operation of an operation part 6. This still picture can be transmitted to a portable telephone system with the same function through a control part 4, a signal processing part 2 and a transmission/reception part 1. On the other hand, still picture data transmitted from outside is similarly received by the transmission/reception part 1 and furthermore displayed on the display part 5 through the signal processing part 2 and the control part 4 to attain easy data communication. |
