(under the class definition) Subject matter which, without proximate human intervention, will actively control a recorder or reproducer mechanism.
(1) Note. Apparatus of this and indented subclasses usually require the sensing of a control signal from the record carrier to control the recorder or reproducer mechanism. However, devices responsive to signals emanating from external devices, or devices responsive to control signals which normally accompany or are a part of an information signal to be recorded or reproduced, are also included in this and indented subclasses.
(2) Note. The signal sensed from the record carrier may be a signal which was magnetically recorded thereon or an electrical or mechanical signal generated by mechanically, electrically or optically sensing an attachment to or modification of the record carrier.

226, Advancing Material of Indeterminate Length,
10+, for material- responsive control means.
242, Winding, Tensioning, or Guiding, 324+, for means for unwinding and rewinding a machine convertible information carrier; e.g., a magnetic tape, particularly subclasses 333+ for automated stop or reversal control for the carrier, subclasses 334+ for a carrier speed or tension control, and subclass 357 for a detector or stop.
318, Electricity: Motive Power Systems, appropriate subclasses, particularly 560+, for automatic motor control devices.
