Characters on a movable character vehicle are identified by a plurality of character readers (flash lamps and TV camera tubes) spaced around the vehicle, and character signals are stored in short term storage registers for each reader. A character imput, such as a tape or the like, is read in advance and compared with the characters in the short term storate registers for coincidence. When coincidence occurs, a comparator cancels the stored signal in the coinciding register and transfers the character to an address store register capable of storing one or more characters, where it is retained until called for by the phototypesetter. The apparatus speeds-up "read-off" time by reading the imput sequence in advance of the output by one or more characters, and by identifying a chosen character and predicting its arrival time.
