A method for the handling of carbon film ribbons and recording on to video tape using a high speed electronic shuttered camera
1990
Abstract A system for recording the information on carbon film typewriter ribbons is described. Ribbons are passed in front of a shuttered camera and recorded on video tape for later transcription and/or examination. The procedure eliminates excessive handling of the tape. Use of the shuttered camera permits the images to be recorded at higher speeds than with a conventional camera.
