Abstract: An automatic threading apparatus in a magnetic tape transport is disclosed in which a flexible sprocketed guide tape loop 70 is disposed in a continuous guide channel 71 which is shaped to conform to the shape of the complex tape path extending from the supply reel 13 to the take-up reel 25 of the magnetic tape transport. The guide tape 70 is driven by a sprocketed gear to move in sliding engagement with grooves in the side flanges of the channel 71 in either direction to move a leader block coupling device 72 attached to the sprocket tape 70 from a first position adjacent the supply reel where the leader block 14 is coupled and decoupled from the device 72 to a second position associated with the take-up reel 25 where the leader block 14 is maintained coupled to the device 72 and caused to rotate relative thereto by and with the take-up reel 25 during a winding operation. The coupling pin 86 is substantially co-axial with the reel 25 during this operation. The leader block 14 and the pin 86 are automatically coupled together during insertion of the cassette 12.
