Abstract

Disclosed is a portable electronic device that is capable of transforming into a first state and a second state and that is equipped with an antenna which is disposed such that in the first state said antenna is near a magnetic field-shielding part and communication is not possible and in the second state said antenna is separated from the magnetic field-shielding part and communication is possible. This portable electronic device (1) is equipped with: an operation-unit-side chassis (2); a display-unit-side chassis (3); a connecting part (4) that connects the operation-unit-side chassis (2) and the display-unit-side chassis (3) such that transformation to the first state and to the second state are possible; a magnetic field-shielding part (170) disposed in the operation-unit-side chassis (2); and an antenna that is disposed in the display-unit-side chassis (3), and in the first state is disposed in a proximal position which is near the magnetic field-shielding part (170), and in the second state is disposed in a separated position which is farther from the magnetic field-shielding part (170) than the proximal position.

Claims

1. A portable electronic device, comprising;

a first body;

a second body;

a connecting portion that connects the first body and the second body so as to be transformable into a first state and a second state;

a magnetic field shielding portion that is disposed in the first body; and

an antenna that is disposed in the second body, disposed in an adjacent position that is adjacent to the magnetic field shielding portion in the first state, and is disposed in a separated position that is more separated from the magnetic field shielding portion than the adjacent position in the second state.

2. The portable electronic device according to claim 1, further comprising a magnetic sheet that is disposed in the second body,

wherein the magnetic sheet is disposed between the magnetic field shielding portion and the antenna in the second state.

11. The portable electronic device according to claim 1, wherein communication with an external device via the antenna is performed when the antenna forms a loop, and

wherein communication with an external device via the antenna is disabled when the antenna does not form a loop.

3. A portable electronic device, comprising;

a first body including a first face;

a second body including a second face and a third face;

a connecting portion that connects the first body and the second body so as to be transformable into a first closed state in which the first face and the second face are disposed to be superimposed in a state of being adjacent to each other, and a second closed state in which the first face and the third face are disposed to be superimposed in a state of being adjacent to each other;

a magnetic field shielding portion that is disposed in the first body; and

an antenna that is disposed so as to be closer to a side of the first face of the second body.

4. The portable electronic device according to claim 3,

wherein the antenna is disposed in an adjacent position that is adjacent to the magnetic field shielding portion in the first closed state, and

wherein the antenna is disposed in a separated position that is more separated from the magnetic field shielding portion than the adjacent position in the second closed state.

5. The portable electronic device according to claim 3, further comprising a magnetic sheet that is disposed so as to be closer to a side of the third face of the second body.

6. The portable electronic device according to claim 5, wherein the magnetic sheet is disposed between the magnetic field shielding portion and the antenna in the second closed state.

7. A portable electronic device, comprising;

a magnetic field shielding portion that is disposed in the first body; and

an antenna that is disposed in the second body, disposed in an adjacent position that is adjacent to the magnetic field shielding portion in one of the opened state or the closed state, and is disposed in a separated position that is more separated from the magnetic field shielding portion than the adjacent position in another one of the opened state or the closed state.

8. The portable electronic device according to claim 7, wherein the antenna in a state of being disposed in the adjacent position is adjacently disposed so as to be superimposed with the magnetic field shielding portion.

9. A portable electronic device, comprising;

a first body including a first face;

a second body that is disposed so as to be superimposed on a side of the first face of the first body;

a connecting portion that includes a rotational axis extending in a direction intersecting the first face of the first body, and connects the first body and the second body so as to be relatively rotatable around the rotational axis and transformable into a first state and a second state;

a magnetic field shielding portion that is disposed in the first body; and

an antenna that is disposed in the second body, disposed in an adjacent position that is adjacent to the magnetic field shielding portion in one of the first state or the second state, and is disposed in a separated position that is more separated from the magnetic field shielding portion than the adjacent position in another one of the first state or the second state.

10. The portable electronic device according to claim 9, wherein the antenna in a state of being disposed in the adjacent position is adjacently disposed so as to be superimposed with the magnetic field shielding portion.
