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.
