Abstract
An automatic tape threading device transfers a tape leader and its associated tape from a supply reel, past a transducer head, to a take-up reel. It is comprised of a threader arm having a perpendicular threader pin which follows an arcuate path defined by an overhead cam. The overhead cam guides the threader pin from a first predetermined position, which relates to a leader block associated with the supply reel, to a second predetermined position, which relates to a receiver mechanism within the take-up reel.
