Abstract: Photosensitive sheet handling apparatus and method for phototypesetters. Accurate control of the lateral positioning of the sheet (i.e., film) is provided by the use of tapered drive rolls. The apparatus includes an input cassette, a film input drive assembly comprised of tapered pinch rollers and a lateral film edge locating stop, a slightly tapered vacuum film drive drum having a collar or flange on one side in accurate alignment with the edge locating stop of the pinch rollers, a motor operated output drive assembly also comprised of tapered pinch rollers and a film edge locating stop in accurate alignment with the drum flange, and a periodically operated film winding mechanism located within an output cassette. The tapered rolls urge one edge of the film against the flange of the drum and stops of the pinch rollers to maintain accurate alignment. Chambers are provided for receiving loops of film at the input and output sides of the drum.

Abstract: Character matrices are stored in and retrieved from a magazine automatically. The matrices can be complete discs or pie-shaped "petals" which are assembled to form a disc. A single pivotably-mounted support arm is used to support the spinning disc, and to move it for selection of concentric arrays on the disc, as well as for storage and retrieval of matrices. A reversed zoom lens is used to magnify the characters.The character spacing carriage can move continuously in order to increase the speed of operation. Proper location of the characters can be done by simply altering the carriage speed between projections, or by using a shuttling lens for character spacing compensation, together with flash delay and carriage deceleration.A system for inputting images from any one of three separate discs also is provided.A double-dove prism and optical wedges are used for altering the shapes of characters.

Abstract: The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums. The characters are located in arrays such as concentric rows on a disc. A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage. Character spacing is determined by motion of the lens carriage and/or the lamp carriage. Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage. A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like. This avoids the necessity of providing a separate headlining machine.

Abstract: The photocomposing machine has an integral keyboard and is especially useful in composing headlines and similar graphic material. A zoom lens is used to provide infinitely variable magnification of the characters. An especially simple manual zoom lens magnification control mechanism is provided, together with an electrical digital display device for indicating accurately the setting of the zoom lens. A line measure display is provided to indicate the total length of a line of characters being composed. The line measure is automatically re-calculated and a new measure is displayed after a change of the zoom lens setting, or of the "set size", so as to give an up-to-date reading of the line measure with the new size. Character widths are stored in pluggable read-only memory chips, one type style per chip. Kerning and white-space reduction values for each style are stored in the same chip as the width values. A rotary disc is used as a character matrix. The disc has characters in a plurality of concentric rows.
