Abstract

A camera support structure of a video presenter includes a first support rod having one end portion rotatably installed with respect to a main body of the video presenter, a second support rod rotatably extended from the other end portion of the first support rod, a first joint portion maintaining the first support rod rotatable with respect to the main body of the video presenter, a second joint portion maintaining the first support rod and the second support rod rotatable between 0° through 180° with respect to each other and elastically supporting the first support rod and the second support rod with respect to each other, and a third joint portion maintaining a camera rotatable with respect to the other end portion of the second support rod and elastically supporting the second support rod and the camera with respect to each other.

Claims

1. A video presenter having a camera support structure, comprising:

a first support rod having one end portion rotatably installed with respect to a main body of the video presenter;

a second support rod rotatably extended from the other end portion of the first support rod;

a first joint portion for rotatably connecting the first support rod with respect to the main body of the video presenter;

a second joint portion for connecting the first support rod and the second support rod rotatable between 0°

through 180°

with respect to each other and elastically supporting the first support rod and the second support rod with respect to each other; and

a third joint portion for rotatably connecting a camera with respect to the other end portion of the second support rod and elastically supporting the second support rod and the camera with respect to each other.

2. The video presenter as claimed in claim 1, wherein the second joint portion comprises:

a shaft portion fixed to the other end of the first support rod and having a ring type shaft protruding from a bottom surface of a cylindrical portion of the shaft portion;

a shaft receiving portion fixed to one end portion of the second support rod and having an accommodation hole formed in a bottom surface of a cylindrical portion of the shaft receiving portion to accommodate the ring type shaft of the shaft portion;

a fixing plate fixed with respect to the ring type shaft of the shaft portion from an inner side of the bottom surface of the cylindrical portion of the shaft receiving portion; and

a spring arranged between the inner side of the bottom surface of the cylindrical portion of the shaft receiving portion and the fixing plate.

3. The video presenter as claimed in claim 2, wherein an outer side of the bottom surface of the cylindrical portion of the shaft portion faces an outer side of the bottom surface of the cylindrical portion of the shaft receiving portion.

4. The video presenter as claimed in claim 2, further comprising a first friction ring arranged between the outer side of the bottom surface of the cylindrical portion of the shaft portion and the outer side of the bottom surface of the cylindrical portion of the shaft receiving portion.

5. The video presenter as claimed in claim 2, further comprising a second friction ring arranged between the inner side of the bottom surface of the cylindrical portion of the shaft receiving portion and the ring spring.

6. The video presenter as claimed in claim 2, wherein a guide protruding portion is formed in an arc shape on a surface of the ring type shaft of the shaft portion, and a guide groove into which the guide protruding portion is to be inserted is formed in the fixing plate.

7. The video presenter as claimed in claim 1, wherein the third joint portion comprises:

a shaft portion having a camera fixing bracket integrally formed with the shaft portion and fixed to the camera and having a ring type shaft protruding from the bottom surface of the cylindrical portion of the shaft portion;

a shaft receiving portion fixed to the other end of the second support rod and having an accommodation hole formed in a cylindrical portion of the shaft receiving portion to accommodate the ring type shaft;

a fixing plate fixed with respect to the ring type shaft of the shaft portion from an inner side of the bottom surface of the cylindrical portion of the shaft receiving portion; and

a spring arranged between the inner side of the bottom surface of the cylindrical portion of the shaft receiving portion and the fixing plate.

8. The video presenter as claimed in claim 7, wherein the spring has a half ring shape and includes a curved protruding portion protruding from a flat surface of the spring.

9. The video presenter as claimed in claim 7, wherein a spring accommodation groove to accommodate the spring is formed in the inner side of the bottom surface of the cylindrical portion of the shaft receiving portion.

10. The video presenter as claimed in claim 8, wherein a spring accommodation groove to accommodate the spring is formed in the inner side of the bottom surface of the cylindrical portion of the shaft receiving portion.

11. The video presenter as claimed in claim 7, wherein a ball plunger is installed at the bottom surface of the cylindrical portion of the shaft receiving portion, and a ball of the ball plunger is inserted into a concave portion formed in the fixing plate.

12. The video presenter as claimed in claim 7, further comprising a friction ring arranged between an outer side of the bottom surface of the cylindrical portion of the shaft portion and an outer side of the bottom surface of the cylindrical portion of the shaft receiving portion.

13. A video presenter comprising:

a camera;

a table for placing an object to be photographed by the camera; and

a camera support member for supporting the camera with respect to the table, the camera support member including;

a first support member connecting relative to the table and rotatable in a first direction; and

a second support member connecting relative to the first support member and rotatable in a second direction opposite to the first direction.

14. The video presenter as claimed in claim 13, wherein the rotation of the second support member relative to the first support member is limited between about 0°

and about 180°

.

15. The video presenter as claimed in claim 13, further including a first joint member for the rotatable connection of the first support member relative to the table.

16. The video presenter as claimed in claim 15, wherein the first joint member includes a frictional element for providing friction during the rotation of the first support member with respect to the table.

17. The video presenter as claimed in claim 13, further including a second joint member for the rotatable connection of the second support member relative to the first support member.

18. The video presenter as claimed in claim 17, wherein the second joint member includes a frictional element for providing friction during the rotation of the second support member with respect to the first support member.

19. The video presenter as claimed in claim 13, wherein the camera is rotatable relative to the second support member.

20. The video presenter as claimed in claim 19, further including a third joint member for the rotatable connection of the camera relative to the second support member.

21. The video presenter as claimed in claim 20, wherein the third joint member includes a frictional element for providing friction during the rotation of the camera with respect to the second support member.

22. The video presenter as claimed in claim 13, wherein the first and second support members define cavities therein for providing a passage for electricity cables.
