非接触膜厚測定方法が知られている。2. Description of the Related Art Conventionally, as a method for measuring the thickness of a coating film on a metal plate, for example, as disclosed in JP-A-6-229709, from a set reference position to a metal plate surface. And an eddy current measuring device for measuring the distance between the reference position and the coating film surface.
There is known a non-contact film thickness measuring method in which an optical measuring device using a light source wavelength of up to 350 μm is integrated, a difference between respective distances is calculated, and a thickness of a coating film is obtained.

この場合は測定誤差が大きくなるという問題点がある。However, in the above prior art, when an optical displacement meter for measuring the reflection intensity in the former non-contact film thickness measuring method is used, the wavelength of the light source is affected by the color. Although the thickness is 200 to 350 μm, it is affected by the color, inclination and roughness of the coating film surface, so that the flatness of the substrate (corresponding to a metal plate) and the coating film surface and the roughness of the coating film surface Is often not constant,
In this case, there is a problem that a measurement error increases.

度が要求される塗工装置には不都合な方法であった。In the latter contact-type film thickness measuring method, in order to use the contact-type film thickness meter for measuring the coating film thickness of a metal plate coated on the entire surface, the coating film must be partially shaved after drying. In addition, measurement in the undried state is impossible, and when measurement is performed after drying, the feedback to the coating film thickness control unit is delayed, the yield rate is reduced, and shavings are generated and the cleanliness is reduced. This was inconvenient for the required coating equipment.
