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.
