Abstract

A portable type information processing terminal device is provided which includes a substrate carrying a substantially annular antenna coil thereon, a signal processing integrated circuit element arranged inside the antenna coil, a magnetic plate arranged under the substrate and a metal plate arranged under the magnetic plate, which are integrally formed and arranged on one or more than one metal parts including a battery pack. The metal plate is used to substantially regulate the resonance frequency of the antenna coil so that it is allowed to be arranged in a cabinet of the portable device.

Claims

1. A portable-type information processing terminal device, comprising:

a substrate carrying a substantially annular antenna coil thereon;

a signal processing integrated circuit element arranged in an inside of the antenna coil;

an annular magnetic plate arranged on the substrate which includes an aperture for allowing the signal processing integrated circuit element to escape; and

a metal plate arranged on the magnetic plate;

wherein the substrate, the magnetic plate and the metal plate are integrally-formed and arranged in a cabinet.

2. A portable-type information processing terminal device according to claim 1, wherein the metal plate includes a recess corresponding to the aperture of the magnetic plate for allowing the signal processing integrated circuit element to escape.

3. A portable-type information processing terminal device according to claim 1, wherein the magnetic plate is arranged under the antenna coil.

4. A portable-type information processing terminal device according to claim 3, wherein the metal plate is arranged under the magnetic plate.

5. A portable-type information processing terminal device according to claim 4, wherein a metal frame of a battery is arranged under the metal plate to increase an inductance of the antenna coil.

6. A portable-type information processing terminal device according to claim 1, wherein an antenna coil of a non-contact type IC card and an antenna coil of a reader/writer circuit are arranged close to each other on the substrate.
