Banknote Deposit Device Serial Number Tracking for Fault Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote deposit and withdrawal devices without temporary retention sections face challenges in differentiating between customer-inserted and device-retained banknotes, especially during faults, leading to inefficiencies and prolonged identification processes.
Innovation Solution
A banknote deposit and withdrawal device equipped with a verification section, serial number acquisition section, control section, and memory section that records serial numbers and storage sequences of banknotes, allowing for reliable differentiation and efficient conveyance even during faults by using a service aperture, conveyance paths, and switching mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all banknotes in the stacking section are re-verified one by one to identify customer banknotes during a fault, then the banknotes can be differentiated, but it takes a long time to identify the banknotes
Solution Approach 1:
The system performs preliminary actions by recording serial numbers and storage positions of all banknotes before a fault occurs. When a fault happens, the control section uses these pre-recorded data to quickly identify customer banknotes without re-verification, thus resolving the contradiction between reliability and time consumption.
2Ease of operation
If a temporary retention section is added to differentiate banknotes, then banknote differentiation is easier, but the device configuration becomes more complex
Solution Approach 1:
Instead of adding a physical temporary retention section, the system creates a data copy of banknote information (serial numbers and storage positions) in the memory section. This virtual copy allows easy differentiation of banknotes without increasing physical device complexity.
3Reliability
If all banknotes are re-verified during a fault, then customer banknotes can be identified, but the process cannot be completed if the fault prevents re-verification
Solution Approach 1:
The system prepares cushioning data by recording serial numbers and storage positions of all banknotes before faults occur. This pre-prepared information acts as a buffer that ensures banknote identification can proceed reliably even when faults prevent normal re-verification processes.

AI summary
The present invention provides a banknote deposit and withdrawal device including: a verification section that verifies banknotes inserted through a service aperture for performing a transaction of banknotes; a serial number acquisition section that acquires serial numbers of the banknotes; a control section that controls conveyance of the banknotes in the device; and a memory section that, for each of one or plural storage cassettes in which the banknotes are stored in the device, memorizes the serial numbers of banknotes stored in the storage cassette and memorizes a storage sequence of the banknotes as administration information, wherein the control section conveys a banknote to a corresponding storage cassette, on the basis of a result of verification, and records the serial number of the banknote and the storage sequence of the banknote in the storage cassette in the memory section as administration information.
