PURPOSE:To quickly execute laser beam machining for a material to be worked having two or more surfaces approximately orthogonally crossed. CONSTITUTION:In a laser beam machine to execute laser machining on a material to be worked such that a material to be worked having X surface 11 and Z surface 12 approximately orthogonally crossed (for example outer 10) is irradiated with the laser beam light from a laser source, the first irradiation mouth 41, which irradiates the laser beam L on X surface 11 as one side, and the second irradiation mouth 42, which irradiates the laser beam on Z surface as other, are arranged in a laser machining head 30. Also, the machine is arranged with a reflection mirror 51 and an optical path switching means 50 to selectively switch either to an optical path from the laser source reaching the first irradiation mouth 41 without reflected on the reflection mirror 51 or to an optical path from the laser source reaching the second irradiation mouth 42 with reflected at the reflection mirror 51 in the laser machining head 30. |
