Abstract: There is provided a slitting-material slitting apparatus including: a rotatable male blade; a female blade that is provided below the male blade; and a wrap section that wraps a slitting-material around the female blade such that the slitting-material makes contact with the female blade on a coated layer side of the slitting-material configured by a support body with a coating layer on the support body harder than the support body; wherein the relative position of the male blade and the female blade are determined such that the male blade slits the slitting-material in a state in which the coating layer is wrapped against the female blade by the wrap section and in contact with the female blade.

Abstract: A cutting device is provided with a lower blade, an upper blade and a collar. Inkjet paper, in which an ink-receiving layer is formed on paper, is wound around an outer periphery face of the lower blade, and a blade tip is formed at one axial direction end of the lower blade. The upper blade rotates with a blade tip thereof opposing the blade tip of the lower blade in the axial direction, and the upper blade cuts the inkjet paper from the paper side thereof. The collar supports the inkjet paper, which is wound around the collar at a position that is separated from the lower blade in the axial direction. A portion of the collar, including shoulder curve portions at the two axial direction ends thereof, is constituted with PTFE.
