DEFINITION

Classification: 400/44

Including line-spacing mechanism:

(under subclass 23) Subject matter wherein significance is attributed to a typewriter in which type-face* elements impact against a record-medium* that is backed by a flat platen* at a print-point*, and wherein significance is also attributed to effecting relative movement between the record-medium and the print-point in a step-by-step manner so that successively imprinted print-lines* will be spaced apart by line-space* distances.
