PURPOSE: An apparatus for measuring the dimension of a coating is provided to facilitate calibration. CONSTITUTION: An apparatus for measuring the dimension of a coating includes a camera, a roller (2), a scale (54), and a scale retaining part (50). The camera, which is positioned at a predetermined position separated from a sheet (1), captures an image for the dimension of the coating. The roller transfers the sheet. The scale is placed in the longitudinal direction of the roller, and implements a numerical calibration process on the dimension of the coating. The scale retaining part retains the scale on the roller, and is capable of freely inserting and removing the scale. |
