Therefore, it is possible to simply and easily perform the setup work for the laser processing (plate processing) of the flat work W and the laser processing (bar processing) of the bar-shaped work W'. In particular, since the urging force of the gas spring 130 is used when lifting the light shielding box 78 from the inside of the flat plate pallet 12, it is possible to more easily perform the setup work for flat plate processing and bar processing.

Further, as described above, each movable piece 156 is urged toward the locking hook 140 by the tension spring 158 in a state in which the holding member 148 and the receiving member 144 cooperate to sandwich the connecting member 138 . Therefore, even if locking failure (fastening failure) between the female locking member 160 and the male locking member 162 occurs, it is possible to sufficiently prevent the light shielding box 78 from being detached from the connecting member 138 .

Furthermore, since the light shielding box 78 can be placed on standby on the upper side of the side wall 52 when bar material processing is not performed, the dead space around the fiber laser processing machine 10A can be utilized to effectively utilize the space in the factory. can be planned.

It should be noted that in another embodiment of the present invention, instead of configuring the regulating roller 118 to be rotatable around the horizontal rotation axis 118c, as shown in FIGS. may be configured as possible.
