Title: Electric typewriter with memory unit - prepares punched or magnetised tape allowing correction of errors and selection of type face before final printing
IPC: B41J2/42
Filed: 1976-06-15
Abstract: The electric typewriter allows a choice between different type faces, correction of typed texts, and their recording in a memory unit for subsequent typing automatically.
