  • Patent number: 7275005
    Abstract: An inspection system inspects appearances of a plurality of worked products held by a sheet-like inspection target sheet, and includes an image processing station provided at a first location and defect detection stations provided at one or a plurality of second locations away from the first location. The appearance inspection system includes a marking station. The image processing station images each of the worked products held by the inspection target sheet and extracts image-processed data serving as an inspection target. The defect detection station displays on a computer the image-processed data to urge an operator to detect a defect part, and outputs detection result data including position data on the defect part, based on an instruction from the operator. The marking station gives onto the image-processed inspection target sheet a mark representing the defect part, based on the detection result data output by the defect detection station.
