Abstract
Electronic components such as integrated circuit components have rows of parallel leads extending from the sides of their bodies. In detecting bent leads of an electronic component, at least two measuring lines are set along each row of leads. The intersections between the measuring lines and the leads are extracted and processed to detect a bend in leads. The electronic component is photographed to produce image data which is stored in a memory. At least two measuring lines are virtually set along the row of leads of the image data stored in the memory. An intersection extractor extracts, from the image data, the intersections between the measuring lines and predetermined leads in the row of leads. A detector then uses the extracted intersections to detect bent leads.
