Subsequently, an end portion of the material 10 may be supported by a pedestal 120 installed inside the main body 100, that is, at an end side of the cutting standby region 111.

The light irradiator 210 according to the present invention receives an electrical signal from the controller 230 and irradiates a line beam to a predetermined position of the surface of the material 10 that is introduced into the cutting standby region 111. The line beam has a predetermined length, but along a line axis in a width direction of the material 10.

Accordingly, the cutting line CL may be displayed on the surface of the material 10, that is, the upper surface, in the form of a line beam.

The cutting schedule line CL may be a line that is substantially cut by the cutting blade 310.
