Solution Overview
Problem
Automated banking machines lack efficient systems for reading and processing various types of documents, such as checks and currency bills, which can lead to errors and inefficiencies in transactions.
Innovation Solution
The implementation of a system that includes a card reader, document alignment mechanisms, magnetic and optical sensors, and a processing path for documents, allowing for accurate reading and verification of documents, including checks, through magnetic and optical indicia analysis, and storage solutions for accepted documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated banking machines process documents without specialized alignment and sensing systems, then device complexity is reduced, but measurement precision and reliability of document reading deteriorate
Solution Approach 1:
The system performs preliminary alignment of the document edge with the magnetic read head before actual data reading occurs. This preliminary positioning action ensures that when the magnetic indicia passes under the read head, the reading operation can proceed with high precision without requiring complex real-time adjustments during the reading process itself.
Solution Approach 2:
A non-contact sensor acts as an intermediary element to detect the document's position and guide its alignment. This sensor provides feedback about the document's location relative to the magnetic read head, enabling the system to adjust the document positioning without requiring direct mechanical intervention or complex integrated positioning mechanisms.
2Adaptability or versatility
If multiple document types are processed through a single deposit accepting device, then adaptability is improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The deposit accepting device is designed with universal functionality to handle multiple document types including checks and currency bills through a single integrated system. The magnetic read head and sensor array can detect and process different document formats, eliminating the need for separate specialized devices for each document type while maintaining operational simplicity through unified control.

Implementation Method 1
magnetic indicia such as the micr line or other portion thereof, read through operation of one or more magnetic sensors such as a magnetic read head
Implementation Method 2
scanning sensors which are operative to read optical indicia on each side of the check
Data Source
AI summary
A system for sensing coded records and structures for sensing coded records are used to sense sheets including notes and checks. An automated banking machine includes a deposit accepting device. The deposit accepting device is operative to receive a stack of sheets and to separate each sheet from the stack through operation of a picker. Each sheet is aligned with the sheet path and analyzed by analysis devices including at least one magnetic read head, an imager and/or a validation device. Sheets determined not to have at least one property of a genuine sheet are returned to a user of the machine. Sheets determined to have at least one property of genuine sheets are processed and stored in the machine.
