1. At the position for releasing the head table, the FR
gear is meshed with the FWD reel gear. Because the
ratchet in the REV ree! gear stops rotating, the tape
must be wound up until no slack exist.
2. Because the rotation stops when no slack exists in
the tape, sensing is performed. The sensing arm
presses the ATSC lock arm, and the lock of the cam
gear with protruded head gets out of position. Then,
the cam gear is made to rotate.
