<P>PROBLEM TO BE SOLVED: To provide an optical inspection device that can not only excellently discriminate a defective seal or the like caused by biting of a film packaging bag for packing a food product or a wrinkle thereof but also can be easily installed on an existing facility later. <P>SOLUTION: The optical inspection device comprises: an illumination section 2 that irradiates an inspection object 1 to be conveyed by a conveying mechanism with illumination light in a gap part provided in the conveying mechanism; an imaging section 3 that images the inspection object 1 in the gap part; an image processing section that processes an image based upon imaging data of the inspection object 1 imaged by the imaging section 3; and a quality-determination section that determines quality based upon a result of the image processing. A passage detecting section 6, which can detect a passage of the inspection object 1 passing through the gap part, is provided in such a manner that an optical axis of the passage detecting section passes through the gap part in a tilted state in a width direction of the conveying mechanism. <P>COPYRIGHT: (C)2012,JPO&INPIT |
