(under subclass 24) Subject matter wherein the book that is being typed on is supported against movement away from the type-face* that is impressed against the book, the support being an elongated member that is circular in cross section.
(1) Note. The back or supporting is similar in configuration to a cylindrical platen*, but the book is not partially wrapped about the platen as in the usual typewriter where the record-medium* encompasses the platen through approximately 180 deg.. In this typewriter, the book is
approximately tangent to the surface of the cylindrical backing.
