PURPOSE:To correct a suction position after an IC element is sucked by arranging a positioning means, centripetally, concentrated and separated along with vertical movement of a sucking pipe, along the periphery of the tip part of a suction pipe to suck the IC element to its tip. CONSTITUTION:A suction pipe 18 rises together with an elevating cylinder 8 and a coupling cylinder 15, and rising is stopped through contact of an upper end 8B of the elevating cylinder 8 with an outer cylinder 3. However a pipe shaft 11 continues its rising and a rotation cylinder 5 is rotated through the passage of a lock pin 13, elevated togetherwith the pipe shaft 11, through a bent part 6c of a bent slot 6 from below. Press pieces 25 are simultaneously moved in a centripetal direction, and an IC element being in an eccentric state and displaced in a direction is corrected. After a centering finger is moved to a desired position, by bringing the interior of the suction pipe 18 into a normal pressure state after the suction pipe 18 is lowered, the IC element is placed in correct attitude in a correct position. |
