Abstract: An inverting apparatus for reorienting electrically asymmetrical axial lead electronic devices in a testing and sorting machine has a wheel rotatably mounted in a magnetic output bin of the tester/sorter. The bin has sets of permanent magnets mounted in its side walls that create two oppositely directed magnetic fields that define upper and lower regions of the output bin. The axis of rotation of the wheel is generally aligned with the magnetic fields across the bin. The wheel carries a set of holder assemblies each mounted for free rotation on its outer circumference. Each holder assembly carries a bar magnet that aligns the holder assembly, and a device carried in the holder assembly, with the prevailing magnetic field. As the wheel rotates the holder assemblies and the devices they carry are transported from the magnetic field in the upper region to the oppositely directed field in the lower region. The bar magnet rotates the holder assembly and the device 180.degree.
