The pellet picking apparatus of claim 8, wherein the cylindrical body has seven suction holes having approximately equal circular cross-sections. 10. The pellet picking apparatus of claim 7, wherein said plurality of suction holes approximate a U-shaped line. 11. The pellet picking apparatus of claim 6, wherein said stage is moveable horizontally along the X-axis. 12. A pellet picking method for separating a pellet adhered to an adhesive sheet from the sheet and picking the pellet thus separated; the method comprising the steps of: (a) providing a stage having a surface with which a lower face of the adhesive sheet is contacted; the pellet being adhered on an upper face of the sheet; the stage having a suction hole that pulls down the sheet; the suction hole having a suction end to be contacted with the sheet on the surface on the stage; the stage being movable to translate and rotate in a horizontal plane with respect to a specific reference position; (b) providing a collet for holding the pellet by a suction force; the collet having a suction end to be contacted with the pellet; the collet being capable of holding the pellet by the suction force at the suction end; (c) placing the sheet on the surface of the stage in such a way that the pellet on the sheet is located at the reference position; (d) holding the pellet by the suction force at the suction end of the collet while at the same time holding the sheet at the suction end of the suction hole of the stage and moving the stage in the horizontal plane with respect to the reference position to thereby detach the sheet from the pellet; and (e) picking the pellet thus detached from the sheet by the collet. 13. The method according to claim 12, wherein the hole is located under the pellet; and wherein an outer part of the hole is located outside of the pellet. 14. The method according to claim 13, wherein the stage is one of: translational and rotational horizontally. 15. The method according to claim 12, wherein the stage has a protrusion on which the surface with which the lower face of the adhesive sheet is contacted while the suction hole is formed on the surface of the stage other than the protrusion; and wherein the outer part of the pellet is located outside of the protrusion and sucked by way of the auction hole. 16. The method according to claim 15, wherein only the protrusion of the stage is moved in a horizontal plane when the sheet is detached from the pellet. 17. The method of claim 12, wherein the stage has a cylindrical body and a movable member built into the cylindrical body. 18. The method of claim 17, wherein the moveable member approximates a rectangular parallelpiped. 19. The method of claim 18, wherein the cylindrical body has a plurality of suction holes arranged along the approximately rectangular periphery of the movable member. 20. The method of claim 19, wherein the cylindrical body has seven suction holes having approximately equal circular cross-sections. 21. The method of claim 18, wherein said plurality of suction holes approximate a U-shaped line. 22. The method of claim 17, wherein said stage is moveable horizontally along the X-axis.
