The gap between the cover sidewalls 17b allows the hooked lower cover 17 and the guide panel 13 to be separated from each other.

The other side of the upper surface 412a2 of the body 412 in which the blade portion 414 is not formed is in a state in which the blade portion 414 is inserted into the coupling space S between the lower cover 17 and the guide panel 13. When the lower cover 17 and the guide panel 13 are separated from each other by the lowering of the stage 200, it serves to support the guide panel 13 separated from the lower cover 17.

Separation blade 410 according to another embodiment, as shown in Figure 6b, may include a body 412, and a pair of blades (414a, 414b). Such a separation blade 410 according to another embodiment, each of the pair of blades 414a, 414b is based on the longitudinal direction (LD) of the body 412, both edge portions of the body 412 Same as the blade 414 shown in FIG. 6A except that it is sharply formed.

As a result, at least one separation blade 410 according to the present invention may be formed within a range that is not in contact with the plurality of first coupling members 13c described above. In addition, the blade side 414, 414a, 414b of the separation blade 410 according to the present invention is the side wall cover 17b of the lower cover 17 coupled to each other by the side hook coupling method and the guide side wall of the guide panel 13 Since the lower cover 17 and the guide panel 13 are separated from each other in a manner of opening the gaps between the portions 13a, the shape of the lower cover 17 and the guide panel 13 are not limited.

4 and 5, the blade lifting unit 420 may include a lifting block 421, a lifting rail 423, a blade lifting member 425, and a support bracket 427.

The lifting block 421 is coupled to the lower portion of the separation blade 410. The lifting rail 423 serves to guide the lifting of the lifting block 421.
