DEFINITION

Classification: 234/89

(under subclass 59) Device (and not classifiable in any other class) wherein the invention relates to the pattern or record to be used with the device and/or the mechanism for reading or sensing a pattern or record.

(1) Note. A patent to a pattern-controlled selective cutting device may be placed as an original in this subclass if it discloses but does not claim specific pattern-controlled means for selecting tools.

(2) Note. A pattern or a senser for use in the control of auxiliary mechanism not claimed, may be found in this subclass.

(3) Note. A patent which is originally classified elsewhere in this class should be cross-referenced in subclass 89 if it discloses novel pattern or senser structure not elsewhere provided for in the schedule.
