Abstract: Included are a chute arranged in an inclined manner to allow sorting targets to flow downward, optical detection means for detecting the sorting targets at a detection position, and ejector means for sorting and removing the sorting targets based on a result of detection of the optical detection means. The chute is provided with an optical detection slit in a direction orthogonal to a flow-down direction of the sorting targets, a slit width of the optical detection slit is adjustable, and the optical detection means images the sorting targets flowing downward on the chute with the imaging means at a position where the optical detection slit is provided as the detection position.

Abstract: An optical sorter includes a light source configured to irradiate a sorting target in transit on a conveyance route with light, an optical sensor configured to detect light emitted from the light source and associated with the sorting target, a determination portion configured to determine whether the sorting target is a foreign object and/or a defective product based on a signal acquired by the optical sensor with respect to the light associated with the sorting target, and at least one intermediate member disposed at a position located between the light source and the conveyance route in a direction in which the sorting target is irradiated with the light from the light source and located in such a manner that the intermediate member does not affect the detection of the light associated with the sorting target. The at least one intermediate member includes a reflection region on which the light emitted from the light source is reflected. The optical sensor is further configured to detect the light emitted from the light source and reflected on the reflection region.
