Abstract: The present invention aims to rapidly and easily create processed data for scan controlling a laser light beam, and to create the processed data for the laser processing apparatus at high precision. A setting plane corresponding to a scanning region of a laser marker is displayed on a processed data generating device. A user operates the processed data generating device to arrange the processing pattern on the setting plane. Here, a marker head coincides an optical axis of the laser light beam L on a position corresponding to the reference point of the processing pattern, and photographs a work W with a camera which light receiving axis is coaxial with the optical axis of the laser light beam L. A photographed image monitor displays the photographed image along with a symbol indicating the position of the light receiving axis of the camera.
