DEFINITION

Classification: 400/112

ANNULAR TYPEWRITER (E.G., FOR TYPING AROUND CIRCUMFERENCE OF PLATEN):

(under the class definition) Subject matter wherein significance is attributed to a typewriter having a cylindrical or partially cylindrical platen* for supporting or backing a record-medium* in which typewriter character* symbols are imprinted on the record-medium in such manner that each successively imprinted character in a direction extending around the periphery of the platen.

(1) Note. Successive characters may be imprinted in a helical arrangement around the periphery, thus requiring no mechanism for line-space* distances, or the platen may be moved axially between successive print-line* typing, thus producing line-spaces.
