ABSTRACT:
A pager terminal device is provided with a receiver circuit, an electronic memory for storing an application program by which received pager-use data are effectively utilized, and a single connector for connecting the receiver circuit and the electronic memory to a host apparatus. This arrangement obviates the necessity of installing an external storage device for storing the application program, and still maintains the portability of the host apparatus. The pager terminal device is further provided with: a connection-discriminating circuit for discriminating the connected state between the pager terminal device and the host apparatus; and an input switching circuit for switching input channels for the pager terminal device so as to provide a connection to the key section of the pager terminal device or to the key section of the host apparatus, in cooperation with the connection-discriminating circuit.
