Abstract

A portable folder-type communication device, including a data input unit; a first hinge axis extending in the lateral direction of the data input unit along the rear end of the data input unit; a connection member rotatable relative to the data input unit about the first hinge axis; a second hinge axis extending in the direction perpendicular to the first hinge axis such that the second hinge axis can rotate about the first hinge axis; and a data output unit rotatable relative to the data input unit about the first hinge axis to allow the data output unit to rotate away from or towards the data input unit and also rotatable relative to the data input unit about the second hinge axis to allow the data output unit to rotate away from or towards the data input unit.

Claims

1. A portable communication device, comprising:

a main housing;

a first hinge axis extending in the lateral direction of the main housing;

a second hinge axis extending in the longitudinal direction of the main housing while being in parallel with at least one side of the main housing; and

an auxiliary housing rotatable relative to the main housing about the first hinge axis to allow the auxiliary housing to rotate away from the main housing and towards the main housing, and the auxiliary housing also rotatable relative to the main housing about the second hinge axis to allow the auxiliary housing to rotate away from the main housing and towards the main housing.

2. The device as set forth in claim 1, wherein the first hinge axis extends in the lateral direction of the main housing along a first end of the main housing, and the second hinge axis extends in the longitudinal direction of the auxiliary housing along a side of the auxiliary housing.

3. The device as set forth in claim 1, wherein the second hinge axis is in a common plane as the first hinge axis.

4. The device as set forth in claim 1, wherein the main housing is provided at at least one side thereof with a first recess for allowing the auxiliary housing to be rotated, the first recess continuously extending along the at least one side of the main housing.

5. The device as set forth in claim 4, wherein the main housing is provided at a second end and the side opposite the first recess with additional recesses.

6. The device as set forth in claim 1, further comprising:

a connection member disposed between the main housing and the auxiliary housing, wherein the connection member is rotated about the first hinge axis when the auxiliary housing rotates about the first hinge axis, and the connection member connects the auxiliary housing to the main housing.

7. The device as set forth in claim 6, wherein the connection member extends parallel to the first hinge axis while being disposed adjacent to the first hinge axis.

8. The device as set forth in claim 1, wherein the second hinge axis is parallel with at least one side of an upper surface of the main housing when the auxiliary housing is positioned flat on the main housing in a closed position, and the at least one side of the auxiliary housing contacts a corresponding side of the main housing when the auxiliary housing is fully rotated open relative to the main housing about the second hinge axis.

9. The device as set forth in claim 1, wherein the longitudinal lengths of the main housing and the auxiliary housing are greater than the lateral widths of the main housing and the auxiliary housing, respectively.

10. A portable folder-type communication device, comprising:

a data input unit;

a first hinge axis extending in a lateral direction of the data input unit along a rear end of the data input unit;

a connection member rotatable relative to the data input unit about the first hinge axis;

a second hinge axis extending in a direction perpendicular to the first hinge axis such that the second hinge axis can be rotated about the first hinge axis; and

a data output unit rotatable relative to the data input unit about the first hinge axis such that the data output unit is rotated away from the data input unit and towards the data input unit, and also rotatable relative to the data input unit about the second hinge axis to allow the data output unit to rotate away from the data input unit and towards the data input unit.

11. The device as set forth in claim 10, wherein the second hinge axis extends along one side of the data input unit when the data output unit is positioned flat on the data input unit.

12. The device as set forth in claim 10, wherein the data input unit includes a keypad comprising a plurality of keys, and the data output unit includes a liquid crystal display unit.

13. The device as set forth in claim 10, wherein the data input unit is provided at at least one side of the upper surface thereof with a recess, the recess linearly extending along the side of the upper surface of the data input unit.

14. The device as set forth in claim 10, wherein the data input unit and the data output unit are each rectangular in shape, and the longitudinal lengths of the data input unit and the data output unit are greater than the lateral widths of the data input unit and the data output unit, respectively.
