An outer housing(70) joined to the rotational housing with an insert pin(60) is rotated by linking with the rotational housing and sets up the direction of the wafer. When a ball screw is rotated by a belt, a block goes down following to the ball screw and a ring shape end goes down while a horizontal end joined to the block is moved vertically following to a linear guide of other vertical end. If the cam-follow(87) inserted into the ring shape end makes the outer housing move down, the outer housing vertically moves down following to the insertion pin. Thus, the wafer sheet(3) is fixed by a wafer support ring(62) and a collet easily picks up the die(4).
