A step part 15 which makes contact to the step part 13 when the weight 7 descends and a flat part 16 which does when the weight 7 ascends 90° are provided to the arm 6. When the weight 7 is in a horizontal position, the arm 6 becomes turnable about the axis 5 and when the weight 7 descended, the arm 6 receives torque in the arrow A direction and the pickup ascends.
