  • Patent number: 4912318
    Abstract: Inspection equipment for inspecting products including medicines such as phials and ampuls and foods such as drinking water. The products are placed on the pedestals of an indexing turn table to be intermittently transferred. The products are held on their peripheral surface by a disk turn table and a pair of rollers and rotated on their own axes by the turn of the disk turn table. The products intermittently transferred are lighted on their surface to be inspected for each stop, inspected by being imaged with an imaging device, and sorted into a nondefective products group and a defective products group with a sorting device.

  • Patent number: 4319269
    Abstract: An external appearance inspecting system is disclosed. In the system, a TV camera is employed for forming a TV image scope. A detection area and an inspection area are electrically created in the TV image scope. The appearance of an image of an object to be inspected is detected by the detection area. Then, the image of the object is inspected by the inspection area. The inspection area is created at the (N+K).sub.th (N=1, 2, 3 . . . , K=1, 2, 3 . . . ) scanning field of the TV image scope, if the image of the object is detected by the detection area which was created at the N.sub.th scanning field.
