Such used returnable bottles often have foreign matters or contaminants such as dust and leavings or cracks, and they must be removed from the bottling line before or after the bottle cleaning process. This invention positively satisfies such a requirement. The foreign matter detecting device comprises: a photoelectric conversion device having a number of light receiving elements; and a video signal processing device for successively subjecting to comparison and discrimination the detection signals of variable two adjacent points which are detected by the photoelectric conversion device, to determine whether or not the bottle has a foreign matter. | |
