Abstract
PURPOSE: To secure the automatic holding for the weight balance by giving adjustment to the angle formed by the guide arm and the vertical face in accordance with the weight change of the accessory units which are added to the vertical movement substance.
CONSTITUTION: In case the weight of additional weight substance 2 added to vertical movement substance 1 varies, switch valve 21 is changed over. And coupling component fixing device 11 is actuated to fix coupling component 4 in the contracted posture of cylinder 11a, and the weight change of substance 2 is detected by weight detector 12 in the form of the output change. According to this output, driving motor 16 is drived automatically until angle α formed by guide arm 8 and the vertical face changes to α'. Then spring axle 15 is turned to shift nut 14 along axle 15. At the same time, the angle formed by arm 8 and the vertical face is detected via angle detector 10 plus gear 9a and 9b which are fixed at the base end part of arm 8, and thus the driving of motor 16 is stopped automatically with angle α'.
