[0012]

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 receiving a radio signal and inputting transmission data, the transmission data includes an external control data identification code, thereby recognizing that the transmission data is control data, and determining whether or not there is an external output instruction. , The state of being able to output to the external device is determined based on the information on the presence or absence of the external connection device, and the control data in the transmission data is output to the external device 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.

Thus, the radio paging signal receiving device can be used not only for displaying a message or simply for controlling the externally connected device but also for both purposes, and the externally connected device can be securely connected. The control data can be output only when the control data is stored, so that the control data is not lost.
