The invention provides a foreign matter detection machine which comprises a machine body with a channel, a detection light emission source installed in the machine body and a photosensitive plate sensor installed in the machine body, a first channel edge and a second channel edge of the channel extend in the left-right direction, and the first channel edge and the second channel edge are distributed at intervals in the up-down direction. The second channel edge is located between the first channel edge and the detection light emitting source in the vertical direction, all detection light rays emitted by the detection light emitting source are distributed in a fan shape and can cover the second channel edge, and the light sensing plate sensor is arranged at the position corresponding to the first channel edge. And the photosensitive plate sensor is also arranged on the side edge of the first channel along the left-right direction. The foreign matter detector solves the problem of detection dead angles, particu
