Abstract

There is provided a mobile communication device. The mobile communication device includes a housing, a fingerprint recognition sensor for inputting fingerprint data, a rotational unit rotatably coupled to a portion of the housing where a keypad is located, the fingerprint recognition sensor being mounted on a top surface of the fingerprint recognition sensor, and a process unit for performing a user identification process by analyzing the fingerprint data inputted from the fingerprint sensor using a fingerprint recognition algorithm.

Claims

1. A mobile communication device comprising:

a housing;

a fingerprint recognition sensor for inputting fingerprint data;

a rotational unit rotatably coupled to a portion of the housing where a keypad is located, the fingerprint recognition sensor being mounted on a top surface of the fingerprint recognition sensor; and

a process unit for performing a user identification process by analyzing the fingerprint data inputted from the fingerprint sensor using a fingerprint recognition algorithm.

2. The mobile communication device according to claim 1, wherein the fingerprint recognition sensor is a slide type sensor where the fingerprint data are inputted by a sweeping action of the finger.

3. The mobile communication device according to claim 1, wherein the rotational unit comprises a guide member formed on both sides of the fingerprint recognition sensor.

4. The mobile communication device according to claim 3, wherein the guide member is formed in a press button structure to provide a switching function.

5. The mobile communication device according to claim 1, wherein the guide member performs a button operation in a vertical direction and is rail-shaped to be fixed in a horizontal direction, thereby having a resistance against a predetermined pressure in the horizontal direction.

6. The mobile communication device according to claim 3, wherein the process unit comprises a user interface for processing click data inputted from the guide member so that the guide member functions as left and right buttons of a mouse.

7. The mobile communication device according to claim 1, wherein the process unit comprises a user interface for generating location data of a mouse pointer by calculating a shade difference between a series of data inputted from the fingerprint recognition sensor to move the mouse pointer on a display unit.

8. The mobile communication device according to claim 7, wherein the process unit comprises selection means for detecting if the fingerprint recognition sensor 110 is used as means for moving a mouse pointer or means for inputting fingerprint data.

9. The mobile communication device according to claim 1, wherein the rotational unit comprises a circular rail coupled to a circular opening formed on the housing and a rotational disk coupled to the circular rail, the fingerprint recognition sensor being coupled to a top surface of the rotational disk.

10. The mobile communication device according to claim 9, wherein the rotational disk and the circular rail are correspondingly coupled to each other through a snap-coupling structure so that the rotational disk can be fixed after the rotational disk rotates by a predetermined rotational angle when outer force is applied to rotational disk.

11. A mobile communication device comprising:

a housing;

a rotation guide unit formed on the housing; and

a rotational unit for rotatably supporting a fingerprint recognition unit, the rotational unit being coupled to the rotation guide unit.

12. The mobile communication device according to claim 11, wherein the fingerprint recognition sensor is a slide type sensor where the fingerprint data are inputted by a sweeping action of the finger.

13. The mobile communication device according to claim 11, wherein the rotational unit comprises a guide member formed on both sides of the fingerprint recognition sensor.

14. The mobile communication device according to claim 13, wherein the guide member is formed in a press button structure to provide a switching function.

15. A mobile communication device comprising:

a housing;

a fingerprint input unit formed on the housing to input a fingerprint rotation guide unit formed on the housing; and

a guide member formed on the housing to guide a sweeping of a finger, the guide member being inclined in a direction of a longitudinal axis.

16. The mobile communication device according to claim 15, wherein the fingerprint input unit and the guide member rotate relative to the housing.

17. The mobile communication device according to claim 15, wherein the guide member functions as a switch.
