Abstract
A holder is rotatably connected to a body . A scribe tool is attached to one end of the holder . A plate spring is fixed to the body , and a receiving plate is fixed to the holder . A piezo-actuator is interposed between the plate spring and the receiving plate . One end of a plate spring having a small spring constant is fixed to the holder . The body is provided with an adjustment screw . When a lower end part of the adjustment screw is protruded, the lower end part presses the plate spring for flexure, thereby generating a resilient force to the plate spring . By this, a rotational force is given to the holder and thus a pressing load directing toward a workpiece is given to the scribe tool
