Method and apparatus for performing head-tail discrimination of electronic chip components

摘要

According to the present invention, a magazine retaining parallel rows of respectively plural chip components is moved relative to an image sensor having a row of picture elements in parallel to the rows of chip components. Plural ones of the picture elements correspond to each chip component. The respective chip components in each row are simultaneously detected for head-tail discrimination by utilizing the difference in light reflectivity between the head and tail sides of the chip component.
