The present invention provides a suction roller which is capable of being adopted for sucking an object. The suction roller is provided with a negative pressure inside thereof and at least one opening for sucking the object by at least one valve disposed in each opening respectively for selectively controlling the on-off of the negative pressure through the opening. During the rotation of the suction roller, the valves in a specific area are capable of being opened so that the negative pressure can pass through the openings with respect to the opened valve to suck the object and transport the object subsequently. In another embodiment, the present invention also provides a transporting apparatus combining the suction roller and a guiding mechanism for transporting the object and compensating the shifting during the moving of the object.

What is claimed is: 1. A suction roller, comprising: a sleeve, having a plurality of first via holes formed thereon; an outer wheel, being received inside the sleeve, having a plurality of second via holes formed thereon at positions corresponding to the plurality of first via holes while configuring a valve inside each second via hole; and an inner wheel, being received inside the outer wheel and configured with a protrusion and at least a slot in a manner that the protrusion is separated from an inner wall of the outer wheel by a minute gap. 2. The suction roller of claim 1, wherein the protrusion is configured with a developing angle, ranged between 10 degrees and 180 degrees. 3. The suction roller of claim 1, wherein each of the first via holes is a circular-shaped hole. 4. The suction roller of claim 1, wherein each of the second via holes is a cone-shaped hole. 5. The suction roller of claim 1, wherein the valve is a formed as a shape selected from the group consisting of: a ball, a cone and a column. 6. The suction roller of claim 1, wherein the valve is made of a material selected from the group consisting of: steel, glass, ceramics, fibers and plastics. 7. The suction roller of claim 1, wherein the sleeve is made of a material selected from the group consisting of: steel, glass, ceramics, fibers and plastics. 8. The suction roller of claim 1, wherein the inner wheel is coupled to a negative pressure source by at least an end thereof for enabling the valves to be subjected to the negative pressure from the negative pressure source through the at least one slot. 9. The suction roller of claim 1, wherein each of the first via holes is an elongated hole. 10. The suction roller of claim 1, wherein each of the second via holes is an elongated cone-shaped hole. 11. The suction roller of claim 1, wherein the inner wheel is attached to two tubes respectively at the two ends thereof as each tube is ensheathed by a bearing and an oil seal component, and each of the two lateral sides of the inner wheel is covered by a cap to be used for fixedly securing the bearing and the oil seal component to the outer wheel. 12. A transporting apparatus, comprising: at least a suction roller, each being mounted on a base to be used for transporting an object while each further being comprised of: a sleeve, having a plurality of first via holes formed thereon; an outer wheel, being received inside the sleeve, having a plurality of second via holes formed thereon at positions corresponding to the plurality of first via holes while configuring a valve inside each second via hole; and an inner wheel, being received inside the outer wheel and configured with a protrusion and at least a slot in a manner that the protrusion is separated from an inner wall of the outer wheel by a minute gap; a negative pressure source, coupled to the at least one suction roller for providing a negative pressure thereto; and a position adjustment unit, coupled to the base for adjusting the position thereof and thus compensating a shifting during the transporting of the object. 13. The transporting apparatus of claim 12, wherein the protrusion is configured with a developing angle, ranged between 10 degrees and 180 degrees. 14. The transporting apparatus of claim 12, wherein each of the first via holes is a circular-shaped hole. 15. The transporting apparatus of claim 12, wherein each of the second via holes is a cone-shaped hole. 16. The transporting apparatus of claim 12, wherein the valve is a formed as a shape selected from the group consisting of: a ball, a cone and a column. 17. The transporting apparatus of claim 12, wherein the valve is made of a material selected from the group consisting of: steel, glass, ceramics, fibers and plastics. 18. The transporting apparatus of claim 12, wherein the sleeve is made of a material selected from the group consisting of: steel, glass, ceramics, fibers and plastics. 19. The transporting apparatus of claim 12, wherein the inner wheel is coupled to the negative pressure source by at least an end thereof for enabling the valves to be subjected to the negative pressure from the negative pressure source through the at least one slot. 20. The transporting apparatus of claim 12, wherein each of the first via holes is an elongated hole. 21. The transporting apparatus of claim 12, wherein each of the second via holes is an elongated cone-shaped hole. 22. The transporting apparatus of claim 12, further comprising: at least a position sensor, each for detecting a position relating to a lateral side of the object. 23. The transporting apparatus of claim 12, wherein the position adjusting unit is capable of enabling a translation motion for adjusting the position of the object. 24. The transporting apparatus of claim 12, wherein the object is made of a material selected form the group consisting of: a soft material and a flexible material. 25. The transporting apparatus of claim 23, further comprising an unwind roller section and a wind roller section. 26. The transporting apparatus of claim 12, wherein the inner wheel is attached to two tubes respectively at the two ends thereof as each tube is ensheathed by a bearing and an oil seal component, and each of the two lateral sides of the inner wheel is covered by a cap to be used for fixedly securing the bearing and the oil seal component to the outer wheel. 27. A suction roller, comprising: a sleeve, having a plurality of first via holes formed thereon; an outer wheel, being received inside the sleeve, having a plurality of second via holes formed thereon at positions corresponding to the plurality of first via holes, each second hole having a valve therein; and an inner wheel, being received inside the outer wheel and being configured with a protrusion that is separated from an inner circumferential wall of the outer wheel by a minute gap, the protrusion activating respective ones of the valves to open and allow corresponding second via holes disposed adjacent to the minute gap to communicate with the minute gap, while respective other ones of the valves close corresponding other second via holes disposed away from the minute gap.
