DEFINITION

Classification: 74/490.13

Planar surface with orthogonal movement or rotation:

(under subclass 490.12) Subject matter in which hand operated elements control both linear movement of a planar surface member (constrained to move along at least one of the three orthogonal spacial axes) or its rotary movement about at least one axis. [figure]

(1) Note. This subclass provides a locus for rotary tables which have only manual inputs to control translation or rotation.
