Pop-up module for electronic device

1. A pop-up module for an electronic device, comprising a pop-up member, and a base where the pop-up member is rotatably installed, wherein the pop up module comprise:

a first elastic member that stores elastic potential energy according to a rotation motion of the pop-up member;

a projection unit that is disposed at the pop-up member;

a moving member that is pressed downward by the pop-up member when the pop-up member is in its shut position in the pop-up module;

a second elastic member, one end of which receives twisting moment by the moving member when the pop-up member is moved to its shut position in the pop-up module;

a first rotating lever unit installed rotatably on the base, wherein one end of the first rotating lever unit receives a force from the second elastic member when the pop-up member is in its shut position in the pop-up module, and a working pin is installed on other end of the first rotating lever unit;

a operating unit including a movement portion having a slot into which the working pin is inserted, and a driving portion driving the movement portion;

a second rotating lever unit rotatably installed on the base, wherein one end of the second rotating lever unit is a contacting portion contacting the movement portion, and other end of the second rotating lever unit is a hanging portion that engages with the projection unit when the pop-up member is in its shut position in the pop-up module; and

a third elastic member that stores elastic potential energy when the second rotating lever unit is rotated.

2. The pop-up module of claim 1 , wherein the pop-up member is installed on the base using a hinge structure.

3. The pop-up module of claim 2 , wherein the first elastic member includes a torsion coil spring that is arranged around a hinge pin of the hinge structure.

4. The pop-up module of claim 1 , wherein a groove is formed in a bottom surface of the moving member, and one end of the second elastic member is inserted in the groove.

5. The pop-up module of claim 1 , wherein the second elastic member includes a torsion coil spring.

6. The pop-up module of claim 5 , wherein the second elastic member is arranged around a first installation pin placed on the base.

7. The pop-up module of claim 1 , wherein a first installation hole is formed in the first rotating lever unit and a second installation pin is inserted into the first installation hole to rotatably install the first rotating lever unit on the base.

8. The pop-up module of claim 1 , wherein an installation hole is formed in a part of the first rotating lever unit which receives a force from the second elastic member, and a part of the second elastic member is inserted into the installation hole.

9. The pop-up module of claim 1 , wherein the operating unit includes a solenoid.

10. The pop-up module of claim 9 , wherein when power is supplied to the solenoid, a magnetic force is discontinued to make the movement portion movable, and when a power is not supplied to the solenoid, the movement portion is fixed due to the magnetic force.

11. The pop-up module of claim 1 , wherein when the movement portion is movable, the movement portion presses the contacting portion due to an elastic force of the second elastic member to move the second rotating lever.

12. The pop-up module of claim 1 , wherein when the movement portion applies a force to the contacting portion to rotate the second rotating lever unit, the projection unit disengages from the hanging portion.

13. The pop-up module of claim 12 , wherein when the projection unit disengages from the hanging portion, the elastic potential energy stored in the first elastic member drives the pop-up member to its pop-up position.

14. The pop-up module of claim 1 , wherein a second installation hole is formed in the second rotating lever unit, and a third install pin is inserted into the second installation to rotatably install the second rotating lever unit.

15. The pop-up module of claim 14 , wherein the third elastic member includes a torsion coil spring that is arranged around the third install pin.

16. The pop-up module of claim 1 , wherein when the pop-up member is moved toward its shut position in the pop-up module, an inclined portion of the projection unit contacts the hanging portion.

17. The pop-up module of claim 16 , wherein when the pop-up member reaches its shut position in the pop-up module, the hanging portion passes from the inclined portion of the projection unit and becomes engaged with the projection unit.

18. The pop-up module of claim 1 , wherein the moving member contacts the pop-up member through an opening in a portion of the base.

19. The pop-up module of claim 1 , wherein the electronic device includes a photographing apparatus and the pop-up member includes a light emitting unit of the photographing apparatus.
