ABSTRACT:
A device for precisely aligning a shuttle (28) in registration with a track from which the shuttle (28) is to receive an integrated circuit electronic device or into which the shuttle (28) is to deposit such a device. The device includes a shaft (42) disposed for rotation about an axis generally parallel to the axis along which the shuttle (28) moves. Pins (44), one corresponding to each of the tracks from which an integrated circuit electronic device is received within the shuttle (28) and the track or tracks into which such a device is to be deposited by the shuttle (28), extend generally radially from the shaft (42). The shuttle (28) carries a notch plate (54) having an open-sided notch (60) formed therein. The notch is defined by a pair of wall edges of a pair of fingers (56) formed in the plate (54). When the shuttle (28) is in a location approximating an intended position at a particular track, the shaft (42) is rotated so that the pin (44), corresponding to the particular track, is urged into the notch (60). As the pin (44) enters the notch (60), lateral adjustment of the shuttle (28) is effected to precisely register the shuttle (28) with the particular track.
