Abstract: 1,091,161. Photographic cameras. A. B. DICK CO. Jan. 28, 1965 [Jan. 28, 1964], No.4161/65. Heading G2A. A line of output from e.g. a computer, is divided into e.g. nine, segments, converted into video signals and each segment in turn is displayed across the face of a cathode ray tube 10 sequentially from left to right (as seen in the Figure). Each image on the tube face is exposed to an array of e. g. nine, reduction lenses 14 each producing a separate image on a film 16, which images overlap slightly. A focal plane shutter 18 is positioned with an opening 18A behind the left hand lens and the shutter is driven in synchronism with the movement of image of the first segment across the tube face so that the shutter follows the image being created on the film by lens No. 1. At the conclusion of the display cycle of the first image, the tube image is on the right hand side of the tube face. The display cycle of the second segment starts on the left hand side of the tube, but this image is prevented from being transmitted through lens No.1 by the focal plane shutter, which has now uncovered lens No.2, through the left hand side of which the tube image is transmitted to the film. This sequence is repeated until the entire output line has been exposed on the film, when a shutter roller 20B energizes the film drive 32 to move the film and present a fresh unexposed line of film behind the shutter. The apparatus is then ready to record a fresh line of output.
