To allow the one-set device to conduct data processing and data transmission processing using a communication line, by providing a main CPU, a memory storing a program, an extension memory storing an extended program, a sub CPU and a display section or the like displaying a processing operation content, to the device.
The device is provided with a main CPU 22 executing processing of a transmission reception signal in a radio communication section and executing data processing, a memory 26 storing a program to operate the main CPU 22, an extension memory 27 storing an extension program of the main CPU 22, a sub CPU 28 assisting the processing of the main CPU 22, and a display section displaying the processing operation content. Then various data are received and processed, and the processing result is sent to a center via a radio communication channel with one operation of a pushbutton. Furthermore, when the device is not used as a portable terminal equipment, the device can be used as a portable telephone set.
