As this is enlarged as a whole, tension is applied to the film 170 in the first direction.

The spacing b of the opposing portions 225 is smaller than the width of the protrusion 248 of the cutting member 240. Therefore, when the protrusion 248 enters the opposing portion 225, the width of the opposing portion 225 expands to b ′ and the contact between the first pressing portion 222 and the second pressing portion 224 increases in width. Tension is applied to the film 170 being made.

In this embodiment, the counter portion 225 is illustrated as having a predetermined interval, but the counter portion 225 may correspond to a portion where the first pressing portion 222 and the second pressing portion 224 are in contact with each other.

The mounting groove 226 is symmetrically formed at both ends of the connection groove 228. The mounting groove 226 has a shape corresponding to the handle 242 of the cutting member 240. When the cutting member 240 is located in the seating groove 226, the width between the first pressing part 222 and the second pressing part 224 is not widened so that tension is not generated in the film 170.

One side of the second pressing portion 224, the coupling portion 234 for coupling the cutting device 200 to the coupling surface 164 of the case 160 is provided.
