When the main cutting blades 12 are arranged side by side, the part preliminarily processed by the preliminary processing unit 11 can be cut by the main cutting blades 12 by reversing the printing medium 5.

  Therefore, for example, in the case of a laminated sheet in which a film is adhered and laminated on a base material via an adhesive layer, when a pressing body is employed as the pretreatment section 11, a portion pressed by the pressing body is cut by the main cutting blade 12. Therefore, it is prevented that it is difficult to cut due to the sticky adhesive layer.

  Therefore, in this embodiment, the blade can be formed in a desired shape as designed, and the printing medium is not wasted. In addition, one of the two cut portions that has conventionally been required is omitted, and the apparatus is compact. It becomes a printing apparatus with excellent practicality that can achieve reduction in cost and cost.
