難であるという不具合があった。When measuring the adhesion strength of a coating film (three-dimensional image such as Braille) 03 formed on a paper with a substrate (paper) 02, a conventional device is used instead of the needle 09. A blade that is parallel to the support table 06 and has a linear contact portion with the base material 02 is pressed against the base material 02 fixed on the support table 06 to move the support table 06, and the resistance force received by the blade is increased. When attempting to measure, the coating film 03 such as Braille may be peeled off to measure the resistance force, but the measured value may not be meaningful because the blade does not ride on the Braille and the Braille is not peeled off. In addition, if you increase the force to press the blade against the base material 02 so that any braille can be peeled off, the frictional force between the blade and the base material 02 increases and the force to peel off the braille becomes relatively small, and the force to peel off the braille is separated. However, there was a problem that it was difficult to measure.
