Abstract

Text composition during either input keying or final copy playout require operator surveillance to insure that desired quality is obtained. This is often difficult due to poorly lighted areas surrounding the writing line. In order to overcome this lighting problem and not interfere with the normal operation of the composing apparatus being utilized, a light projecting element is mounted on the carrier below the print element.

Lighted Writing Line

Text composition during either input keying or final copy playout require operator surveillance to insure that desired quality is obtained. This is often difficult due to poorly lighted areas surrounding the writing line. In order to overcome this lighting problem and not interfere with the normal operation of the composing apparatus being utilized, a light projecting element is mounted on the carrier below the print element.

Referring to the figure, carrier 1 carries print element 2 for printing along platen 3. Also carried by carrier 1 is a writing-line lighting arrangement made up of light source 4, reflector 5, and light transfer triangle 6 formed of glass fibers. The shape and location of triangle 6 is such that a portion of the already printed line, as well as a portion of the unprinted line, will be illuminated and there will be no interference with print element 2.
