Abstract

The printing unit includes a thin, lightweight, circular, bidirectionally shiftable, distensible synthetic resin band having printing characters thereon, along with a single, spring-powered impression hammer for selectively engaging and distending the band toward the page in order to print a selected character. Printing and letter spacing are concurrently initiated and accomplished using only a single, windable, energystoring mainspring and a mechanical energy transmission assembly coupling the rack and gear assembly and printer in parallel. The transmission assembly includes gearing for withdrawing a limited, predetermined amount of motive energy from the mainspring for each printing cycle, and for distributing such energy to achieve band spin and character selection, hammer cocking, and letterspacing translation of the carriage.
