Zusammenfassung:	PURPOSE:To simplify the whole structure of a device, and to correctly adjust the focus position and the nozzle position. CONSTITUTION:The moving operation where a machining head 3 is moved to a work W by a moving device 4, and the abutting operation where a nozzle 12 is moved to the machining head 3 by a coil spring 11 and abutted on the work surface Wa are executed, the distance between a converging lens 9 and the tip of the nozzle 12 is set to the value where the distance of the desired focus position from the work surface Wa is added to the focal distance of the converging lens 9, and the distance of the desired nozzle position from the work surface Wa is subtracted, and the nozzle 12 is fixed to the machining head 3 by a fixing device 14. Then, the nozzle 12 is moved to the desired nozzle position by the moving device 4 together with the machining head 3. The focus position and the nozzle position can be adjusted by one moving device 4.
