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.

Tape threading device

A tape leader block can be restored to and removed from its housing in a tape cassette by a device which comprises a threader arm having a leader block carrier which supports a threader pin. The leader block carrier also is provided with a gear system which engages with a compatible gear system of a rotatable yoke. The yoke terminates in a cam follower which is forced into certain distinct operating positions by powered movements of a camming device. Attainment of these operating positions serves to restore or remove the leader block to and from the tape cassette's leader block housing.

Device for restoring and removing a tape leader block to and from a tape

A device for positioning a threader pin of a magnetic tape threading mechanism in a tape take-up reel comprises a plate having an axial receiver slot for receiving the threader pin and a biasing means such as a raised leaf spring which protrudes into the receiver slot from a mounting position within a contiguous slot.
