DEFINITION

Classification: 242/333

Automated stop or reverse:

(under subclass 324) Subject matter comprising a drive mechanism operative to advance the information-bearing carrier in one direction during winding and a controller to either: (a) halt operation of the drive mechanism, or (b)

cause the carrier to move in a second, opposite direction, without user intervention.
