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 at least one of inside and near the antenna coil;

a magnetic plate arranged on the substrate; 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, if the signal processing integrated circuit element is arranged in the inside of the antenna coil, the magnetic plate includes an aperture for allowing the signal processing integrated circuit element to escape.

3. A portable-type information processing terminal device according to claim 2, 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.

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

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

6. A portable-type information processing terminal device according to claim 5, wherein a battery is arranged under the metal plate.

7. A portable-type information processing terminal device according to claim 2, 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.
