Abstract

A document processing, archival storage and printout system such as for handling customer checking accounts. Original checks/documents are processed into digital image data then stored temporarily in magnetic media and transferred to optical long-term archival storage. The system retrieves and accumulates monthly groups of digital image data, then sorts one-day'"'"'s worth (1/22 of 22 business-day accumulation) by account number so that printing means can print statements, each day, covering 1/22 of the total accounts existing for that month. Massive amounts of data can be accumulated and stored, for example, for 500,000 to 1,000,000 customer accounts, while the system operates to rapidly retrieve and printout sufficient customer statements each day so that each of the many customers will still receive a personal monthly updated statement during the appropriate month.

Claims

1. A system for original document image capture and storage in digital document image form, said system comprising:

(a) document processor means for capturing an electronic image of an original document and converting it to optical digital image data;

(b) storage/retrieval means for reception of, and temporary storage of, said digital image data;

(c) archival subsystem means for transferring said digital image data from said storage/retrieval means to a long-term archival storage means, said archival subsystem means including;

(c1) means to retrieve on a daily cycle, selected elements of said digital image data to eventually cover a specified period of time, such as an N-day cycle of business days, where N might be set for a monthly period of 20-25 days, said selected elements including data representing (i) date of capture of original document;

(ii) customer account number;

(iii) sequential document number (iv) numeric financial quantity involved in each document selected;

(c2) means to transfer and store a one-day-portion of said selected elements of said digital image data into a printing subsystem means;

(c3) temporary storage means for holding 2 N days worth of data on said selected elements;

(c4) means for retrieving, from said temporary storage means, 1 N days worth of data, for use of said printing subsystem means;

(d) said printing subsystem means for sorting on a daily basis, by specified indicia, said selected elements of said digital image data and enabling a printing means to print for each account number, an itemized statement of financial document transactions covering the period of a given N-day cycle.

2. The system of claim 1 wherein said long-term archival storage means includes:

(a) jukebox means holding a plurality of optical disk platters for storage of digital image data of original documents;

(b) storage management archival server means for providing data transfer and communication to/from said jukebox means and an archival library storage means, said archival server means including;

(b1) means for merging identified disk platter and record numbers for each one of said selected elements;

(c) said archival library storage means for providing multiple years storage of digital image data beyond that capable by said jukebox means.

3. The system of claim 2 wherein said storage/retrieval means transmits N days worth of selected elements for data accumulation in said archival subsystem means and said jukebox means, while said storage management archival server means includes:

(a) means for transferring only 1/N, one-day'"'"'s worth, of said selected accumulated elements to said printing subsystem means for printout of said itemized statements during a daily print cycle.

4. The system of claim 1 wherein said document processor means includes:

(a) host computer means for controlling said document capture and including;

(a1) means for retrieving and storing document item data (MICR data) including document capture data, account number, bank ID number and monetary amount;

(a2) means for supplying said document item data to said archival subsystem means to enable said archival subsystem means to merge the document item data with the associated location of its digital image data in said long-term archival storage means to form a Master Print Index file in said archival subsystem means.

5. The system of claim 4 wherein said printing subsystem means includes:

(a) means to receive and sort said Master Print Index File into a specified sequential order.

6. The system of claim 1 which includes:

(a) power encoder means for placing additional MICR information indicia on selected documents being processed.

7. the system of claim 1 wherein said archival subsystem means includes:

(a) means to retrieve, accumulate and store selected elements of digital image data selected for retrieval which encompasses a specified period of time to enable a one-day print cycle;

(b) means to create a Master Print Index File which correlates each retrieved selected element of document image data with its locational position in said long-term archival storage means;

(c) means to transfer said Master Print Index File to said printing subsystem means.

8. The system of claim 7 wherein said printing subsystem means for sorting on a daily basis includes:

(a) means for arranging said Master Print Index File into a sequential order determined by the numerical value of said specified indicia on each document.

9. The system of claim 1 wherein said storage/retrieval means includes:

(a) means for converting said optical image data to magnetic image data for temporary storage and then for transfer to said archival subsystem means.

10. The system of claim 1 wherein said archival subsystem means includes:

(a) interface means to transmit said selected digital image data to a remotely located print subsystem.

11. A method for storage and retrieval of document image data from optical media for sorting the printout of monthly checking account statements, comprising the steps of:

(a) processing financial check documents to convert document information into digital image information;

(b) storing said digital image information on optical platters in a jukebox unit;

(c) creating, via an image data storage disk, an "initial index file" for deposit into an archive server means having fields of data representing;

(i) date of capture of checking document;

(ii) customer account number;

(iii) check number;

(iv) amount of check;

(d) merging, in said archive server means, two additional information fields to the said initial index file so that each of said check numbers is associated with a;

(i) platter number in said jukebox unit;

(ii) a record number on the identified platter;

thus to form a Master Print Index File in said archive server means;

(e) accumulating data into said Master Print Index File in said archive server means, such that all check documents received in optical digital storage during a 30-day monthly period will include the said four fields of the "initial index file" plus the added platter and record number data;

(f) copying said Master Print Index File to a print server means and transferring said 30-day accumulation of Master Print Index File data into said print server means and its magnetic buffer print disk;

(g) sorting, via print server software, said Master Print Index File to sequentially arrange said Master Print Index File according to the customer account number ascending from lower account numbers to higher account numbers;

(h) transferring the image data retrieved from the optical platter jukebox unit to said print server magnetic buffer print disk according to said sorted Master Print Index File;

(i) accessing, via software, said print server means and print disk by means of software to deliver co-related, digital image data to a printer means;

(j) printing out, during each working day of the month, a number "N" of checking account statements where N is equal to 1/22 of the total number of customer accounts.
