The radio signal transmitted from the base station includes a call code and transmission data. The transmission data is simply display data used for display, and the transmission data controls an external device. In some cases, the external control data includes an external control data identification code indicating that the control data is used to perform the control.

When the radio signal is received and the transmission data is input, the transmission data includes the external control data identification code, so that the transmission data is recognized as the control data, and the presence or absence of the external output instruction is recognized. Based on the information about the presence / absence of the external connection device, the state in which the external connection device can be output is determined, and the control data in the transmission data is output to the external device. If there is no external output instruction or an external device is not connected, the control data is stored in the storage device, and when the external output becomes possible, the control device outputs the control data to the external connection device. I do.

As a result, the radio paging signal receiving device can be used not only for displaying a message or simply for controlling an external connection device but also for both purposes, and the external connection device can be reliably connected. Since the control data can be output only when it is set, the control data is not lost.
