DEFINITION
Classification: 346/33
Recorders combined with the means the functioning of which is recorded.
(1) Note. Where a functioning means is claimed broadly as operating a specific recorder, the patents are classified in an appropriate subclass in this class and which subclass includes the structure of the specific recorder.
(2) Note. Where both the functioning means and the recorder are claimed broadly or where modifications of the functioning means are claimed to adapt it to its recording operation or where specific interconnecting structure between the functioning means and the recorder are claimed, the patents are classified in this and in indented subclasses.
(3) Note. For the most part, art devices significantly claimed combined with means to record one or more aspects of the operation thereof, are classified with the art device, see the notes to the class definition.
