(under subclass 35) Apparatus in which there is provided an information carrying device such as a perforated tape, cam or the like, said device being driven or moved independently relative to and not controlled by the motor and means operated by said device for causing the motor to operate in accordance with the information carried thereby.
(1) Note. This definition is limited to those devices in which the information carrying device is driven independently of the motor and would continue to feed control signals to the motor even in the event that the motor is not following (e.g., motor jammed) as distinct from a fixed pattern or the like wherein a follower element is driven by the motor and follows the pattern only because it is driven by the motor. However, this definition includes holding the information carrying device stationary and independently driving a tracer or pick up device over it.
