Abstract

It is from time to time desirable to provide enhanced illumination at or near the writing line of a typewriter. One technique for accomplishing such enhanced illumination is the provision of a light pipe positioned on an axis parallel to the platen 12. The light pipe is provided with illumination from light-emitting members 14 positioned at the end of the light pipe. In order to effect illumination of the writing line region, it is necessary to cause the light rays emitting from light-emitting members 14 to exit the confines of the light pipe 10 and thereby impinge upon the writing page.
