Type arrangement data editing apparatus

A type data editing apparatus in which a group of type data codes transferred from a data source are successively compared to type arrangement data obtained by determining the instantaneous position of a movable carrier, to print a given print symbol of a character set carried on said carrier when coincidence is determined therebetween, said apparatus comprising:

• means for detecting identification and synchronization marks (11) on said carrier and producing an output of the identification and synchronization mark signals for a character set on said carrier;
• means for discriminating between said identification and synchronization mark signals;
• microprocessor means (41) for receiving said identification mark signals coming from said means for discriminating and said synchronization mark signals a recognizing the relational positions of said marks to identify the kind of character set on said carrier and producing a plurality of read-out signals;
• a first memory means (42) storing type arrangement data in a first region thereof and storing a plurality of replacement data in a second region thereof for selectively replacing data on said first region, said first memory means receiving said read-out signals from said microprocessor means, said read-out signals forming address inputs to said first and second regions of said first memory means;
• and
• second memory means storing data (42) read out from said first memory means to form said edited type arrangement data as a function combined type arrangement data as modified by said replacement data.
