ABSTRACT:
A photocomposing machine having a cassette containing a continuous film tape loop. The loop rides on two rollers which stretch the loop when it is inserted on the photocomposing machine. The rollers are spool-shaped to avoid contact with the character containing portions of the tape. A lead plate, which is integral with the cassette, provides proper loop alignment and tension. The illuminating light from the photocomposing machine is directed through the tape and out of the cassette by means of a prism system that extends through the bottom of the cassette. The loop contains character identification and alignment markings which are illuminated through corresponding apertures in the lead plate.
