Typewriter, Electric

A typewriter in which the work of printing or of pre ing the type faces against the paper, or printing ribbon, is done by electro-magnetic attraction. The keys close electric circuits, throwing the electro-magnetic action into play. This involves the use of electricity for what is ordinarily only a mechanical proce . The strength of the impre ion, however, is independent of the touch of the operator. It has not come into very extensive use.
