Abstract: A rotary cutter device has a rotator having a rotary blade including a first blade edge part, and a holding body having a fixed blade including a second blade edge part. The first blade edge part and the second blade edge part are rubbed with each other so as to cut. A rotation-side separating member is brought into contact with the cut object in which a cut portion of the cut object adheres to the first blade edge part and rotating together with the rotary blade from inside in the radial direction and applying a reaction force to the outside. A fixed-side separating member is fixed so as to be located outside a rotation range of the first blade edge part, and is brought into contact with the cut object from outside in the radial direction and constrains movement of the cut object to the outside.

Abstract: A rotary cutter mechanism includes a rotary blade which is rotatably provided around a shaft center and which includes a first cutting edge portion, a counter blade which is provided to face a locus drawn by the first cutting edge portion of the rotating rotary blade and which includes a second cutting edge portion, and a protruding member which is provided on the edge portion of the rotary blade on the first direction side and which protrudes from the rotary blade toward a rotation direction side, the rotation direction side being a side on which the rotary blade faces the object to be cut in a case where the object to be cut is cut between the first cutting edge portion and the second cutting edge portion.
