Abstract: A cutter and a printer having a cutter prevent the paper pieces cut off by the cutter from collecting at the paper exit from which the cut-off pieces are discharged. A stage surface 40defines the bottom edge 5a of the paper exit 5. A sloped guide surface 41 is formed sloping down from the downstream side of the stage surface 40. A first side wall 42 determines where one side of the width of the paper passes over the stage surface 40 and the sloped guide surface 41. A second side wall 43 determines where the other side of the width of the paper passes. A protrusion 47 is formed on the first side wall 42 protruding toward the second side wall 43.When label paper 11 is cut, the cut-off portion 11c is deposited on the stage surface 40 covering the top of the protrusion 47. As a result, the cut-off portion 11c is made unstable by the protrusion 47 immediately after being deposited on the stage surface 40, and slides down easily.
Abstract: Prior to a mark imaging process executed for the purpose of detecting a position of recognition marks for positioning the substrate and the mask, an optical axis calibration processing process of detecting a horizontal relative position between imaging optical axes, and a surface correction data creation processing process of detecting a local positional deviation of the imaging optical axes, which is caused by the travel of the imaging unit, are executed. Before starting production, a production pre-start precision evaluation process for evaluating a substrate positioning precision is executed by using a verification substrate and a verification mask, and after starting the production, a production post-start precision evaluation process for evaluating a substrate positioning precision after starting the production is executed by using a commercial production substrate and a commercial production mask.
