ートカツター。 In an auto cutter that cuts roll paper by a rotary blade meshing with a fixed blade in an X-shape and the meshing points sequentially moving as the rotary blade rotates, the cutting end part of the cutting edge of the rotary blade is drawn. The tip of the cutting edge of the fixed blade is inclined in the rotational direction of the rotary blade compared to the normal direction to the tangent to the trajectory circle at the engagement point of the cutting end portion within a cross section including the trajectory circle. Auto cutter.
