ABSTRACT:
An applied flavoring-material inspecting device suitable to inspect that a flavoring material containing a fluorescent substance is applied on cigarette wrapping paper evenly and in a proper amount. The inspecting device comprises a light source (10) for casting ultraviolet light onto a flavoring-material application surface of cigarette wrapping paper on which a flavoring material with a fluorescent substance added or containing a fluorescent substance is applied, a camera (20) for obtaining an image of the flavoring-material application surface from fluorescence radiated due to the ultraviolet light, and an image processing means (30) for detecting an area of a fluorescence irradiation region in an image for inspection obtained by digitizing the image obtained by the camera and determining an applying state of the flavoring material applied on the cigarette wrapping paper, from the area of the fluorescence irradiation region.
