ABSTRACT:
A cutting device including: a support member; a first blade having a linear-shaped cutting edge extending in a lengthwise direction from a first lengthwise end, to a central portion, and to a second lengthwise end of the first blade, the first blade being supported by the support member; and a second blade having a linear-shaped cutting edge extending from a first lengthwise end to a central portion, and to a second lengthwise end of the second blade, the second blade being supported in confrontation with the first blade by the support member, the first blade and the second blade cutting therebetween a sheet-shaped medium by serially contacting each other from the first lengthwise ends to the second lengthwise ends while the second blade presses against the first blade in a thickness direction of the first blade; wherein at least one of the first and second blades has a smaller deformation resistance, with respect to the support member, in its blade thickness direction at its first and second lengthwise ends than at its central portion.
