Real time storage/retrieval subsystem for document processing in banking operations
First Claim
1. In a bank check document handling system for capturing image and information data of negotiated bank checks for bank record processing and which system is managed by a host computer, a storage/retrieval module subsystem for storing said image and information data for retrieval and conveyance to any one of a plurality of image work stations and printers for conversion to human readable format, said storage/retrieval module subsystem comprising:
- (a) means for receiving digitized optical signals containing bank check document image packets having (i) image data and (ii) sequential non-image information data related to said image data;
(b) means for converting said digitized optical signals to digitized electrical signals forming said bank check document image packets;
(c) storage operation means for storing, in real time, said bank check document image packets on identified areas of magnetic disk units via a file management system which includes;
(c1) first storage file means for storing non-image bank check document data as a plurality of sequential files made up of a sequence of bytes of data;
(c2) second storage file means for storing, in real time, said bank check document image packets in a structured file system made of a plurality of records where each record has a key field with an index identifying each record;
(d) means for retrieving, in real time, a selected bank check document image packet while simultaneous and concurrent storing operations of bank check document image packets are taking place, said means for retrieving including;
(d1) means for selecting said first storage file means or said second storage file means to effectuate retrieval of either or both non-image information and/or a selected bank check document image packet for transmission to a requesting work station or printer;
(e) means for transmitting retrieved bank check document image packets to a work station or printer for display;
(f) means for communicating with a host computer to receive operational instructions and to transmit retrieved sequential non-image information for use by said host computer.

Abstract
A storage/retrieval module apparatus for use in a document imaging system can receive digitized optical image and related information data, convert it to electrical digital data for storage on disk at high rates of speed. Concurrently with storage operations, the storage/retrieval module apparatus can also execute retrieval of stored data under command of a host computer or a connected workstation.

16. In a bank check handling system, controlled by a main host computer, for capturing images and non-image item data from digitized bank check document image data packets being received, a storage and retrieval subsystem for storing compressed image data of the front and back of each bank check document received, and for storing related non-image item data such as customer account number and dollar value amount for each said received bank check document, the storage/retrieval subsystem comprising:
-
(a) a minimum of two disk drive means which include first and second disk drive units for operating first and second disk storage units; (b) said first and second disk storage units being organized into identified files in a file management system; (c) first and second disk controller means for controlling said disk drive means; (d) a first storage processor means for receiving said digitized bank check document image data packets for storage on said first and second disk storage units in real time via said first and second disk controller means and said first and second disk drive means, said first storage processor means including; (d1) first buffer memory means for temporarily storing at least two of said bank check document image data packets; (d2) a file management system for; (i) filing said related non-image item data in a first sequentially ordered file of consecutive bytes, and for (ii) filing said bank check document image packet in a second structured file made of a plurality or records in which each record has a key field with an index identifying each record, (e) a second unit processor means for retrieving, in real time, selected non-image item data or said bank check document image data packets via said first and second disk controller means and said first and second disk drive means for transmission to a requesting work station or printer, said second unit processor means including; (e1) second buffer memory means for temporarily storing at least two bank check document image data packets; (e2) means for executing retrieval operations simultaneously and concurrently with the execution of storage operations by said first storage processor means; (f) optical link controller means for receiving digitized optical signal data in digitized packets and converting said optical signal data to digitized electrical signals for transmission on a parallel system bus means to said first storage processor means; (g) first local area network controller means for communication between a plurality of operator work stations and for facilitating data requests to said second processor means for retrieval, and for transmitting requested image and non-image item data to a requesting work station; (h) second local area network controller means for communicating with said main host computer; (i) said parallel system bus means for enabling concurrent data exchange between said first and second processor means, said first and second disk controller means, said optical link controller means, and said first and second local area network controller means.
