Paper Sheet Processing Apparatus Counterfeit Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facilities with gaming machines equipped with paper sheet processing apparatuses lack effective monitoring, making it difficult to prevent wrongdoing, such as repeatedly inserting counterfeit bills, as users can operate these machines unattended.
Innovation Solution
A paper sheet processing apparatus with an insertion slot, conveyance unit, reading unit, verification unit, control unit, storage unit, and comparison unit that identifies and reports counterfeit bills by comparing inserted paper sheets with stored information, and includes a counter to track repeated instances, enabling timely intervention by administrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If paper sheet processing apparatuses are installed in gaming machines without monitoring, then user convenience and automation are improved, but the ability to detect and prevent wrongdoing deteriorates
Solution Approach 1:
The system implements feedback by sending report signals to host apparatuses when counterfeit bills are detected. The control unit transmits information about detected counterfeit paper sheets to external monitoring systems, enabling remote detection and response to wrongdoing while maintaining unattended operation at the gaming machine location.
Solution Approach 2:
The patent introduces an intermediary communication system between the paper sheet processing apparatus and host apparatuses. This intermediary mechanism allows the apparatus to report counterfeit detections without requiring direct human monitoring at the device, bridging the gap between automated operation and wrongdoing prevention.
2Reliability
If verification and comparison functions are added to detect counterfeit bills, then wrongdoing detection capability is improved, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions including controlling the conveyance unit, managing the storage unit, and executing the comparison operation. By making the control unit multi-functional, the patent avoids adding separate dedicated components for each function, thereby improving counterfeit detection capability while minimizing increases in device complexity.
Solution Approach 2:
The patent merges the verification function and comparison operation into a unified system. The control unit integrates the capabilities to verify paper sheet authenticity and compare stored information, combining multiple detection mechanisms into a single coordinated system rather than separate independent components.
Data Source
AI summary
Provided is a paper sheet processing apparatus capable of distinguishing a counterfeit bill or a paper sheet suspicious to be a counterfeit bill from bills inserted through an insertion slot to stop a wrongdoing. A storage unit stores information on a paper sheet read by a bill reader and a verification unit verifies the paper sheet using the information on the paper sheet stored in the storage unit. If the paper sheet is determined to be counterfeit in the verification, a conveyance unit conveys the paper sheet toward the insertion slot. A comparison unit compares the image data of the inserted paper sheet with image data of a previously inserted paper sheet and if the image data of the inserted paper sheet is determined to be identical to the image data of the previously inserted paper sheet in the comparison, a control unit sends a signal to a host apparatus.
