2. Description of the Related Art Conventionally, for inspection of a transparent or semi-transparent film having protective films attached to both sides, for example, a scratch of a polarizing film used for liquid crystal, accurate inspection results can be obtained by an inspection device equipped. Since it is not possible to do so, it was performed visually by a skilled person.

In the case of a polarizing film, this has a thickness of 5 to 20 μm.
A thin film of about m is attached and the thickness is 100 to 200 μm.
This is because a protective film made of synthetic resin with a thickness of about 30 μm is attached to both sides of the polarizing film formed to a certain degree, and this protective film is generally used in a manufacturing process such as a carrying process and a cutting process. In order to prevent the film itself from being scratched, it is immediately applied after the thin films are bonded together. In this way, the protective film itself is assumed to be scratched, and the protective film remains attached to the product until it is peeled off when it is used at the customer after shipping. is there.

In order to deal with this, a method has been proposed in which the focal length is inspected according to the surface of the polarizing film beyond the protective film by considering the thickness of the protective film of about 30 μm. The product itself had a slight warp in the central part and near the center, and it was impossible to keep the distance from the inspection device to the surface of the polarizing film constant, and it was not put to practical use.

Further, according to the method for inspecting a transparent or semitransparent film of the second aspect of the present invention, a protective film is doubly attached to both surfaces of the transparent or semitransparent film in advance at the initial stage of manufacturing, and the transparent or semitransparent film is conveyed or inspected during the inspection. Since the protective film of the first layer with scratches is peeled off and inspected by the cutting process, the scratches on the surface of the protective film are not mistakenly judged to be scratches of the transparent or semi-transparent film. Since the protective film of the second layer, which is protected by the protective film of the layer, is provided, it is not necessary to make the inside of the detection means an excessively clean space. Further, according to the second aspect of the present invention, it is not necessary to attach the protective film again after the inspection by the detecting means.
