Abstract

A handler (10) for feeding integrated circuit chip carriers (42) into a test site (14) of the handler (10) is the subject matter of this patent application. Inventive features include apparatus whereby carriers (42) are pushed laterally from a bottom end (62) of a magazine track (26) into a conveyor station (58). A pusher bar (64) can include a ramp surface (128) to raise carriers (42) above the particular carrier (42) being moved into the conveyor station (58). Further, the inventive features include structure for remotely sensing the presence of a carrier (42) at the bottom end (62) of a track (26). A rotary shuttle (148) can be incorporated for transporting carriers (42), after they have been tested, to the output section (158) of the handler (10).
