Abstract: A carrying unit is capable of changing the holding force of a carried object, suppressing the deformation amount of a carried object held by suction and dropping the carried object quickly at a predetermined place. A carrying unit has a workpiece holding face opposing a carried object and a carrying head equipped with a concave portion having an air guide face gently continued from a bottom face to a work holding face. A cylindrical nozzle, which forms a slit for discharging air between the carrying head and the bottom face in order to discharge positive pressure air toward the air guide face from that slit, is mounted on the carrying head such that it projects from the bottom face. A central portion of the cylindrical nozzle serves as a vertical nozzle having a vertical hole, which is open substantially in a vertical direction with respect to the carried object for supplying positive pressure or negative pressure air to the carried object, and a flat portion perpendicular to the vertical hole.

Abstract: A non-contact carrying device 10 holds and carries a carried object W in front of a carrying head 12 without making the carried object contact with the carrying head 12. A gas supplying surface 18 in which an opening portion of a gas supplying hole 19 is formed, an annular holding surface 21 projected rather than the gas supplying surface, and a gas guiding surface 22 smoothly connecting the gas supplying surface 18 with the holding surface 21 are formed in a tip surface of the carrying head 12. A nozzle 24 mounted on the carrying head 12 is provided with a base portion 24a mounted on the carrying head 12 and a disk portion 24b facing to the gas supplying surface 18 and forming an annular slit 25 for discharging gas between the gas supplying surface and the disk portion. Since the nozzle 24 is moved in an axial direction with respect to the carrying head 12 by a screw member 35, width of the slit 25 can be changed.
