Attorney, Agent or Firm: Noval; William F.

A magnetic tape recorder includes a rotary head scanner, a cartridge for containing a single reel of magnetic tape having a leader block at its end, a take-up reel and a leader block channel defining a tape path from the cartridge, past the rotary head scanner, to the take-up reel. A tape threading apparatus includes a first rotatably mounted arm segment, a first motor for rotating the first arm segment, a second arm segment rotatably mounted to the first arm segment, a second motor mounted on the first arm segment for rotating the second arm segment and a leader block carrier mounted on the end of the second arm segment for engaging the leader block to move it along the leader block channel.

DETAILED DESCRIPTION According to the present invention, there is provided in a rotary head magnetic tape recorder, apparatus for threading magnetic tape from a single reel magnetic tape cartridge, which is reliable, cost effective and which effects positive control during the magnetic tape threading and unthreading operation.
The tape threading apparatus includes first and second articulated arm segments, a first motor for rotating the first arm segment and a second motor mounted on the first arm segment for rotating the second arm segment.
Preferably, the second arm segment mounts a leader block carrier on flexing elements which allow the leader block carrier to change elevation as tape is threaded in a helical path around a rotary head.
