Abstract

Disclosed is a mobile communication terminal provided with a rotational display unit. The mobile communication terminal comprises: (a) a main housing comprising a first hinge axis formed on one end; (b) a connection member hingedly connected to the main housing so as to be opened from and closed into the main housing around the first hinge axis, and comprising a second hinge axis on the upper surface of the connection member and perpendicular to the first hinge axis; and (c) a rotational housing rotatably connected and opposite to the connection member, and rotated around the second hinge axis.

Claims

1. A mobile communication terminal comprising:

(a) a main housing comprising a first hinge axis formed on one end;

(b) a connection member hingedly connected to the main housing so as to be opened from and closed into the main housing around the first hinge axis, and comprising a second hinge axis spaced apart from and perpendicular to the first hinge axis; and

(c) a rotational housing rotatably connected to the connection member, wherein the rotational housing rotates around the second hinge axis.

2. The mobile communication terminal as set forth in claim 1, wherein the main housing further comprises a keypad provided with an array of a plurality of keys.

3. The mobile communication terminal as set forth in claim 1, wherein the rotational housing includes at least one convex arc-shaped end having a designated radius of curvature.

4. The mobile communication terminal as set forth in claim 3, wherein the connection member further comprises an auxiliary member formed on one end of the connection member and being concave arc-shaped with the designated radius of curvature.

5. The mobile communication terminal as set forth in claim 1, wherein the rotational housing comprises a wide LCD.

6. The mobile communication terminal as set forth in claim 5, wherein the rotational housing comprises at least one speaker unit.

7. The mobile communication terminal as set forth in claim 5, wherein the rotational housing comprises two speaker units, each being individually installed on both ends of the rotational housing, thereby supplying stereophonic sound.

8. The mobile communication terminal as set forth in claim 1, wherein the rotational housing comprises a wide LCD installed on the rotational housing and first and second speaker units, each being individually installed at both sides of the wide LCD.

9. The mobile communication terminal as set forth in claim 1, wherein one end of the connection member is connected to the first hinge axis and an other end of the connection member is connected to an upper surface of the rotational housing.

10. The mobile communication terminal as set forth in claim 1, further comprising a rotational camera lens housing installed on one side of the first hinge axis and provided with a rotational camera lens.

11. The mobile communication terminal as set forth in claim 1, wherein the connection member further comprises a stationary camera lens.

12. The mobile communication terminal as set forth in claim 11, wherein the stationary camera lens faces upward in a perpendicular direction to an upper surface of the rotational housing.

13. The mobile communication terminal as set forth in claim 1, wherein the rotational housing rotates around the second hinge axis to at least an angle of 90°
