Abstract: PURPOSE:To reduce the installation area of a laser beam machine and the size of its mechanism by providing plural machining heads to the laser beam machine and arranging a laser beam changing-over device between a laser beam oscillator and the machining heads. CONSTITUTION:The laser beam oscillator 15 is provided on an upper frame 13 of the laser beam machine 1 and first and second machining heads 33 and 35 are arranged to a supporting frame 17 arranged on the tip of the upper frame 13. Further, the laser beam changing-over device 19 to change over the laser beam in order is arranged at the central part of the supporting frame 17. The laser beam LB emitted from the oscillator 15 is reflected by the changing-over device 19 and made incident on the first machining head 33 and transmitted light is made incident on the second machining head 35 via a reflection mirror 21. Since the heads 33 and 35 are used by changing over in order, a stroke of the machine is reduced and the installation area of the laser beam machine 1 is reduced and the size of its mechanism is reduced.
