Inspection device and system for inspecting foreign matters in a liquid filled transparent container

A foreign matter inspection device for inspecting foreign matters in a liquid filled transparent container comprising:

• a first irradiation light source which is disposed behind the transparent container and irradiates a first irradiation light to the transparent container;
• a second irradiation light source which is disposed adjacent to the first irradiation light source and irradiates a second irradiation light of a different color from that of the first irradiation light from a different direction from that of the first irradiation light to the transparent container;
• a half mirror which is disposed on a transmission light optical path of the first irradiation light from the transparent container as well as on a reflection light optical path of the second irradiation light from the transparent container and performs optical path separation;
• a first filter which is disposed on a straight advancing optical path of the half mirror and selects the transmission light from the first irradiation light;
• a first imaging means which images the transmission light of the first irradiation light selected by the first filter;
• a second filter which is disposed on another optical path of the half mirror and selects the reflection light of the second irradiation light;
• a second imaging means which images the reflection light of the second irradiation light selected by the second filter;
• and
• an image processing means which image processes picture images taken by the first and second imaging means and detects foreign matters in the liquid filled container.
