<P>PROBLEM TO BE SOLVED: To provide an appearance inspection device of a base material, having a simple structure and capable of improving inspection efficiency, when inspecting a color tone and the glossiness of the base material. <P>SOLUTION: The appearance inspection device comprises a light source 2, a visible light detector 3, an ultraviolet light detector 4, and a control device 5. The light source 2 irradiates a base material 1 which is an inspection target with light extending from a visible light area to an ultraviolet light area. The visible light detector 3 receives and detects the light in the visible area which is irradiated from the light source 2 and reflected by the base material 1. The ultraviolet light detector 4 receives and detects the light in the ultraviolet light area which is irradiated from the light source 2 and reflected by the base material 1. The control device 5 determines the presence/absence of color tone failures of the base material 1 on the basis of the detection result of the visible light detector 3, and determines the presence/absence of glossiness failures of the base material 1 on the basis of the detection result of the ultraviolet light detector 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
