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. This disc preferably is segmented, with one complete font of characters on each segment. A relatively simple arrangement is provided for changing from one row of characters to the next.
