A hinged arm assembly can be used to pull a tape from a supply reel and thread it past transducers and tape guides into a take up reel for further unreeling of the tape from the supply reel. The hinged arm assembly is connected at one end to a rotatable threading shaft. The end of the hinged arm is guided by a cam surface that defines the path of the tape. An idler wheel is automatically inserted between the drive shaft and the threading shaft for the reverse operation by tripping a Y bracket that offcenters a spring to urge the idler wheel into contact with the drive shaft after a rotation of the threading shaft into the winding position.
