A holder 20 is rotatably connected to a body 10. A scribe tool 30 is attached to one end of the holder 20. A plate spring 16 is fixed to the body 10, and a receiving plate 26 is fixed to the holder 20. A piezo-actuator 40 is interposed between the plate spring 16 and the receiving plate 26. One end of a plate spring 50 having a small spring constant is fixed to the holder 20. The body 10 is provided with an adjustment screw 60. When a lower end part 65 of the adjustment screw 60 is protruded, the lower end part 65 presses the plate spring 50 for flexure, thereby generating a resilient force to the plate spring 50. By this, a rotational force is given to the holder 20 and thus a pressing load directing toward a workpiece is given to the scribe tool 30. |
