Abstract

In typewriters or other impact printers, characters having relatively small surface areas, such as periods and commas, have a tendency to penetrate further into paper and platen rubber upon impact than do larger characters. For a given print system, the depth of penetration is dependent primarily upon the peak force (F) generated by the impact of the type element and the paper. It is possible to reduce this force by placing a spring between the type element and the mass containing most of the kinetic energy responsible impact.
