When a digital image recording means records digital image on an image recording medium based on order information or on digital image data, a computing means calculates digital image layout information, and calculates, based on the digital image layout information, X-cut size information used for cutting the image recording medium in the direction perpendicular to the conveyance direction of the conveyance means and Y-cut size information used for cutting the image recording medium in the direction perpendicular to the cutting direction for the X-cut. A cutting means which cuts the image recording medium into a prescribed size has an X-cut means to cut the image recording medium in the direction perpendicular to the conveyance direction of the conveyance means in accordance with the X-cut size information and a Y-cut means to cut the image recording medium in the direction perpendicular to the cutting direction of the X-cut in accordance with the Y-cut size information.
