Abstract: To provide a means that is less likely to misidentify a crack as a foreign substance during an image checking in which a vibration is applied to a powder contained in a bag-like container. A foreign substance checking system includes a vibration device configured to apply a vibration to a container, a photography device configured to optically photograph the inside of the container through a transparent region from the outside, and a determination device configured to determine whether a foreign substance is present inside the container based on an image of the container photographed by the photography device. The vibration device includes a rotating shaft and a hammer rotating in conjunction with the rotating shaft and colliding with the container. A portion of an outer surface of the hammer to abut on the container has a flat surface.

Abstract: A foreign matter inspection system that is less likely to misidentify a crack as a foreign matter during an image inspection in which a vibration is applied to a powder contained in a bag-like container. The foreign matter inspection system includes a vibration device configured to apply a vibration to a container, a photography device configured to optically photograph the inside of the container through a transparent area, and a determination device configured to determine whether a foreign matter is present inside the container based on an image of the container photographed by the photography device. The vibration device alternately applies weak vibrations W and strong vibrations S to the container. The determination device determines whether the foreign matter is present inside the container based on the image of the container photographed by the photography device when the vibration device applies the weak vibrations W.
