Abstract

A mobile radio terminal device is of such a double-backing type as to connect an upper casing and lower casing to each other by a hinge. The lower casing includes an input section and a battery. The upper casing includes an antenna, a circuit board having a CPU, a semiconductor memory and a radio circuit, and an interface connectable to various kinds of devices including an external antenna. By a connection line pattern of the circuit board, the antenna and interface are connected to the radio circuit.

Claims

1. A mobile radio terminal device comprising a first casing having a display displaying an image and a second casing having a battery for supplying power, said first and second casings are connected by way of a hinge comprising;

an antenna provided in the first casing and configured to receive and transmit radio signals; and

a radio communication part provided in the first casing and configured to generate signals to be received and transmitted via the antenna.

2. A mobile radio terminal device according to claim 1, wherein the first casing further includes a first connection part configured to make an electrical connection between an external antenna and the radio communication part.

3. A mobile radio terminal device according to claim 1, wherein the first casing further includes a GPS receiving part configured to receive a signal from a GPS (Global Positioning System) satellite.

4. A mobile radio terminal device according to claim 1, wherein the first casing includes a second connection part configured to make a data communication with an outside through an electrical connection.

5. A mobile radio terminal device according to claim 1, wherein the second casing further includes a second connection part configured to make a data communication with a outside through an electrical connection.

6. A mobile radio terminal device according to claim 1, wherein the second casing further allows a third connection part configured to allow a memory medium to be attached and detached and read out information from the memory medium.

7. A mobile radio terminal device according to claim 1, wherein the first casing further includes a memory part configured to store information and a battery for supplying electric power to the memory part to allow the information which is stored in the memory part to be retained.
