ABSTRACT:
Articles, such as rectangular thin film circuits (11), are sorted by advancing a row of the articles along a chute (20). The leading article (11-A) in the row is stopped in a test position with a releasable stop member (40), after which the lead article is tested for a characteristic, such as by a photoelectric detector (41) that scans a circuit and detects the absence or presence of an ink mark (16) previously applied to a defective circuit. If the article is of a first type (good circuit), the stop 40 is released so that the lead article advances further to a receiver (30). If the article is of a second type (bad circuit), a mechanism (45) is operated to eject the article transversely from the chute (arrow C). Preferably, an article to be ejected is pivoted (arrow F) about a transverse axis (F) to disengage the trailing edge (48) of the lead article (11-A) from the leading edge (49) of a following article (11-B) prior to ejection from the chute.
