Barrel module and imaging apparatus including the same

1. A barrel module comprising:

a base having a surface on which an image pickup device is disposed;

a lens barrel disposed on the base;

a driver for providing driving power to move the lens barrel up and down over the base;

a clip connected to the driver to be disposed between the driver and the lens barrel; and

an elastic member for providing elasticity between the lens barrel and the clip,

wherein:

the lens barrel moves from an original position toward the base when an external force is applied, and when the external force is removed, the lens barrel goes back to the original location due to the elasticity of the elastic member; and

the base comprises:

an accommodator for accommodating the image pickup device; and

a guide rib formed on the accommodator toward the lens barrel, and for providing a moving path for the clip while engaging with the clip.

2. The barrel module of claim 1 , wherein the base further comprises:

first and second guide bars formed on the accommodator toward the lens barrel and spaced apart from each other; and

wherein the first and second guide bars guide a moving path of the lens barrel by connecting with the lens barrel.

3. The barrel module of claim 2 , wherein the lens barrel comprises:

a center portion to which a lens is installed; and

a curved portion extending from the center portion and having a depression formed on a side of the curved portion to connect to the guide rib.

4. The barrel module of claim 3 , wherein the lens barrel further comprises first and second connectors respectively connected to the first and second guide bars so that the lens barrel moves along the first and second guide bars.

5. The barrel module of claim 2 , wherein the driver comprises:

an actuator for providing the driving power as rotatory power; and

a shaft connected to the actuator to rotate based on an axis in a length direction of the shaft according to the rotatory power,

wherein a screw thread is formed on a perimeter of the shaft to be screwed to the clip.

6. The barrel module of claim 5 , wherein the clip comprises:

a body portion having a through hole having an inner surface on which a screw thread is formed to be screwed to the shaft; and

a depressed portion formed as a depression on a side of the body portion to be connected to the guide rib and moved along the guide rib.

7. The barrel module of claim 1 , wherein one end of the elastic member is connected to the driver and another end is connected to the lens barrel.

8. The barrel module of claim 7 , wherein the driver further comprises a first fixer to be connected to the end of the elastic member.

9. The barrel module of claim 7 , wherein the lens barrel further comprises a second fixer to be connected to the other end of the elastic member.

10. The barrel module of claim 1 , wherein the elastic member is a coil spring.

11. The barrel module of claim 1 , wherein the clip and the lens barrel are adhered to each other magnetically.

12. The barrel module of claim 11 , further comprising:

a first magnetic body disposed on a surface of the lens barrel facing the clip; and

a second magnetic body disposed on a surface of the clip facing the first magnetic body,

wherein the clip and the lens barrel are adhered to each other magnetically via the first and second magnetic bodies.

13. The barrel module of claim 1 , wherein the clip and the lens barrel are formed of a magnetic material to be adhered to each other magnetically.

14. An imaging apparatus including the barrel module according to claim 1 .
