<p>A laser beam machine for processing an article to be processed with a laser beam from a processing scanner 1 comprised of an optical system employing a laser oscillator 10. Article position controllers 2a and 2b are controlled in a coordinated manner in accordance with the direction of the laser beam from said processing scanner 1 such that the position of a surface to be processed of the article is controlled to be nearly perpendicular to the direction of the laser beam from the processing scanner 1. While an article to be processed mounted on one article position controller 2a is being processed and unloaded, another article to be processed can be loaded onto the other article position controller 2b. Thus, the wait time for the laser beam machine can be reduced and production efficiency can be improved.</p>
