(under subclass 545) Subject matter wherein the typewriter is provided with a platen* that is supported in its typing position solely by platen-supporting rollers underlying the platen, and wherein incremental rotation of the platen is effected by incrementally rotating said platen-supporting rollers that are in frictional contact with the platen.
(1) Note. This form of platen support does not require bearings and carriage* structure to support the ends of the
platen, thereby making it possible to type on a record-medium* piece that is wider than the length of the platen. For feeding of such a piece, see subclass 623.
