PROBLEM TO BE SOLVED: To enable widening of the span of an auxiliary clamp without expanding the groove of a front table by arranging one pair of diagonally vertical-moving mechanisms at the side surface of a manipulator frame and connecting arms having holding part as the auxiliary clamp of the manipulator. SOLUTION: This manipulator Mp is shifted by holding a work W along the groove of the front table. The work W is transferred from the manipulator clamp Mp to a work holding clamp. A piston cylinder 5 of the diagonally vertical-moving mechanism Ks drives one pair of arms 3 diagonally downward. Plural holding parts (auxiliary clamp) 2 arranged at the tip parts of the arms 3 are descended along the guide 4a of a fixing member 4 to clamp the end part of the work W. The work holding clamp is opened to execute the processing to the work W with a plate material processing machine P. Since the span 1 of the holding part (auxiliary clamp) 2 can be clamped with the wide width, the dislocation is not developed even in the case of loading the external force to the work W.
