The lifting guide 2 is erected to the turntable provided on the stand 1 and a lifting machine frame 3 is assembled to the guide 2. The hand arm 4 which extends and contracts in the horizontal direction is assembled to the frame 3 and the chucking part 5 which can be vertically rotated is provided to the top end of the arm 4. The guide 2, the mechanism 3 and the hand part of the arm 4, etc. are horizontally rotated by a horizontally rotating mechanism A. The base plate of the hand part is slid by the function B relative to the immersion nozzle.
