Abstract

A reader/sorter reads documents which include MICR, OMR and OCR encoded characters. The reader/sorter reads each type of character sequentially at separate read head positions. Character codes read by a particular head address a separate area of address locations in a random access memory which stores equivalent character codes which are used by the data processing system. The random access memory is loaded with the translated character codes, allowing a data processing system to communicate with the reader/sorter.

Claims

1. A document processing system comprising:

a reader/sorter having at least one of a plurality of read heads for reading magnetic ink character recognition characters, optical mark recognition characters, or optical character recognition characters, or combinations thereof for reading their respective fields of documents and including means for generating character code signals during a store operation;

and adapter coupled to said reader/sorter during said store operation and having storing means responsive to said character code signals for generating corresponding translated character code signals during said store operation;

a data processing system coupled to said adapter and having means for receiving said translated character code signals for processing information from said documents during said store operation, said data processing system having means for generating said translated character code signals during a load operation;

said storing means during said load operation including;

receiving means coupled to said data processing system for receiving said translated character code signals;

character count means coupled to said data processing system for generating character count signals for receiving a first initial count, and being incremented for each of said translated character code signals receiving from said data processing system;

selection means coupled to said character count means and responsive to said character count signals for generating address location signals;

quadrant count means coupled to said data processing system and said character counting means for receiving a second initial count for generating quadrant count signals, and being incremented when said character counting means stores a predetermined value, said quadrant count signal being indicative of said one of said plurality of read heads; and

,

memory means coupled to said receiving means, said selection means, and said quadrant count means for storing said translated character code signals at an address location specified by said address location signals and said quadrant count signals,

wherein said selection means is further responsive to said character code signals from said reader/sorter for generating said address location signals during said store operation;

said memory means being coupled to said selection means and said quadrant count means, and being responsive to said address location signals and said quadrant count signals, for generating said translated character code signals for transfer to said data processing system during said store operation.

2. The document processing system of claim 1 wherein said plurality of heads equals four.

3. The document processing system of claim 2 wherein said predetermined value equals 128.

4. The document processing system of claim 3 wherein said memory means comprises four quadrants, each of said quadrants comprising 128 of said address locations for storing said translated character code signals, each of said address locations of said quadrant being addressed by said address location signals generated by said selection means in response to character code signals from a particular read head of said reader/sorter.
