Abstract
In an inspection device for inspecting for possible foreign matters contaminating a liquid filled transparent container, a red color illumination unitA is disposed behind a glass containerfilled with liquid and a pair of blue color illumination unitsB andC are disposed so as to sandwich the red color illumination unitA. Both the red color and blue color illumination unitsA,B andC are disposed so that the red color light transmits through the glass containerand the blue color light reflected by a possible foreign matter in the liquid merges with the red color transmission light. Both the transmission light and the reflection light are separated by a color separation mirrorand are imaged by CCD camerasandso as to detect both black color series and white color series foreign matters can be detected at the same time.
