PURPOSE: A confirmation system of the displacement of a workpiece is provided to settle a workpiece carried by a transfer tool to a working table without error. CONSTITUTION: A prepared workpiece is delivered into a processing machine and transferred to a working table. The workpiece is placed on the working table and air is blown into holes formed on the working table for confirming settlement. Disorder of the holes is decided by sensing pressure change of a pneumatic gauge connected to the holes. When there is not a pressure increasing pneumatic gauge, the workpiece is placed on the working table and settled. The settlement of the workpiece on a right position is decided. If there are more than two of pressure increasing pneumatic gauges, the workpiece is clamped and the accurate fixation of the workpiece of the working table is decided. If there are more than three of pressure increasing pneumatic gauges, processing is performed to the workpiece. After processing the workpiece, the workpiece is unclamped. The displacement of the workpiece from the working table is decided. If there are more than two of pressure increasing pneumatic gauges, the workpiece is lifted from the working table to take out the workpiece from the processing machine.
