A control method of an embossing apparatus including a support member on which a medium to be processed is adhered, a first driving device configured to move the support member in a first direction parallel to a major surface of the support member, a cutting tool including a blade, an embossing tool which recesses the medium to be processed by pressing, a second driving device configured to move the cutting tool and the embossing tool in a second direction parallel to the major surface of the support member and different from the first direction, a first pressing device configured to move the cutting tool in a third direction perpendicular to the major surface of the support member, and a second pressing device configured to move the embossing tool in the third direction, characterized by comprising: a step of moving, by the first driving device and the second driving device, the cutting tool to a position facing a predetermined first target position of the medium to be processed; a step of sticking, by the first pressing device, the blade into the first target position of the medium to be processed, and then stopping the blade in a state in which a blade edge is positioned between upper and lower surfaces of the medium to be processed; a step of forming a cut line in a boundary between a non-processing portion which is not embossed and an embossing portion by moving the support member in the first direction by the first driving device, and moving the cutting tool in the second direction by the second driving device, in the state in which the blade edge is positioned between the upper and lower surfaces of the medium to be processed; a step of moving the cutting tool to a position where the blade is pulled out from the medium to be processed, by the first pressing device; a step of moving the embossing tool to a position facing a second target position along the cut line of the medium to be processed, by the first driving device and the second driving device; a step of pressing, by the second pressing device, the embossing tool against the second target position, and thereby forming a recess in the medium to be processed; and a step of forming, after the step of forming the cut line, the embossed portion in the medium to be processed by a continuous recess extending along the cut line and breaking the boundary at the cut line, by moving the support member in the first direction by the first driving device, and moving the embossing tool in the second direction by the second driving device, in the state in which the embossing tool is pressing the medium to be processed. a step of moving, by the first driving device and the second driving device, the cutting tool to a position facing a predetermined first target position of the medium to be processed; a step of sticking, by the first pressing device, the blade into the first target position of the medium to be processed, and then stopping the blade in a state in which a blade edge is positioned between upper and lower surfaces of the medium to be processed; a step of forming a cut line in a boundary between a non-processing portion which is not embossed and an embossing portion by moving the support member in the first direction by the first driving device, and moving the cutting tool in the second direction by the second driving device, in the state in which the blade edge is positioned between the upper and lower surfaces of the medium to be processed; a step of moving the cutting tool to a position where the blade is pulled out from the medium to be processed, by the first pressing device; a step of moving the embossing tool to a position facing a second target position along the cut line of the medium to be processed, by the first driving device and the second driving device; a step of pressing, by the second pressing device, the embossing tool against the second target position, and thereby forming a recess in the medium to be processed; and a step of forming, after the step of forming the cut line, the embossed portion in the medium to be processed by a continuous recess extending along the cut line and breaking the boundary at the cut line, by moving the support member in the first direction by the first driving device, and moving the embossing tool in the second direction by the second driving device, in the state in which the embossing tool is pressing the medium to be processed.
