An orientation parts feeder for successively feeding parts wherein each part has an irregular cross section. The feeder includes a rotating drum supported for rotation about a substantially horizontal axis. The drum has on its inner cylindrical surface a plurality of circumferentially spaced wing plates, a transfer chute having a longitudinal parts guide channel, and a first and a second incorrectly-oriented-parts discriminating and removing mechanism disposed in succession on a downstream end portion of the parts guide channel. The first incorrectly-oriented-parts discriminating and removing mechanism has a response time which is shorter than that of the second incorrectly-oriented-parts discriminating and removing mechanism. The feeder is able to remove parts having undesirable postures with sufficient reliability and stability to ensure a high speed conveyance of the parts.
