Abstract
An apparatus for inspecting the outward appearance of each of IC packages stored in an embossed tape includes a drive wheel having an outer periphery about which the embossed tape is wound. The drive wheel is rotatable in a vertical plane for moving the embossed tape. A pair of cameras are so mounted as to face the outer periphery of the drive wheel at its upwardly and downwardly moving portions, respectively, and are used to produce two different images of each IC package from two different angles through a cover tape bonded to the embossed tape for enclosing the IC packages. The apparatus prevents any diffused reflection of light by the cover tape and any inclination of each IC package during its inspection.
Claims7
In an apparatus for inspecting the outward appearance of each of IC packages stored in an embossed tape one after another by inspecting its image formed through a cover tape bonded to said embossed tape, the improvement which comprises:
- a drive wheel having an outer periphery about which said embossed tape is wound, said drive wheel being rotatable in a vertical plane for moving said embossed tape;
- and
- a pair of image forming cameras facing said outer periphery of said drive wheel at its upwardly and downwardly moving portions, respectively.
In an apparatus for inspecting the outward appearance of each of IC packages stored in an embossed tape one after another by inspecting its images formed through a cover tape bonded to said embossed tape, the improvement which comprises:
- a plurality of drive wheels each having an outer periphery about which said embossed tape is wound, said drive wheels being rotatable for moving said embossed tape;
- and
- a plurality of image forming cameras so mounted that one of said cameras may face said outer periphery of one of said drive wheels at its upwardly moving portion, while another faces said outer periphery of another of said drive wheels at its downwardly moving portion.
