Cash Processing Device Recirculating Cassette Separating Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recirculating cash processing devices cannot return banknotes that have been paid in directly into a storage-only cassette, as these devices lack a separating function, preventing the return of paid-in media.
Innovation Solution
A cash processing device with a pay-in section, a pay-out section, a medium identification section, and storage sections that include both stacking and separating functions, allowing for the temporary holding and subsequent return of banknotes based on classification results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If banknotes are directly paid into a storage-only cassette without a separating function, then storage capacity is improved, but the ability to return paid-in banknotes is lost
Solution Approach 1:
The storage system is segmented into two distinct types of cassettes: storage-only cassettes for bulk storage and recirculating cassettes with separating functions for banknotes requiring return capability. This segmentation allows the system to simultaneously maximize storage capacity while preserving the ability to return specific banknotes through recirculating cassettes.
Solution Approach 2:
Recirculating cassettes act as intermediary storage sections between the storage-only cassettes and the pay-out section. Banknotes that need to be returned are transferred to recirculating cassettes, which provide the necessary separating function to feed out individual banknotes, thus enabling the return capability while maintaining efficient bulk storage in storage-only cassettes.
2Productivity
If all banknotes are stored in storage-only cassettes for efficient storage, then storage efficiency is improved, but flexibility in banknote handling is reduced
Solution Approach 1:
The banknote storage system is divided into storage-only cassettes for efficient bulk storage and recirculating cassettes for flexible handling. This segmentation enables the system to achieve high storage efficiency while maintaining operational flexibility through the recirculating section.
Solution Approach 2:
The system dynamically assigns banknotes to different cassette types based on their handling requirements. Banknotes requiring return capability are directed to recirculating cassettes, while others are stored in storage-only cassettes, optimizing both storage efficiency and handling flexibility through dynamic resource allocation.
3Device complexity
If a storage-only cassette without separating function is used, then device complexity is reduced, but functionality for returning banknotes is limited
Solution Approach 1:
The cassette system is segmented into storage-only cassettes with simple structure and recirculating cassettes with separating functions. This segmentation allows the overall system to achieve return functionality while keeping individual storage cassettes simple and easy to manufacture.
Solution Approach 2:
Recirculating cassettes serve multiple functions: they provide bulk storage like storage-only cassettes and additionally provide the separating function needed for returning banknotes. This multi-functionality allows the system to achieve return capability without adding excessive complexity to every cassette.

AI summary
Provided is a cash processing device including a pay-in section, a pay-out section, a medium identification section, one or plural medium storage sections that each includes a stacking function and a separating function, a temporary holding section that includes a stacking function and a separating function, and a pay-in processing section that, based on a classification result by the medium identification section for a medium taken in through the pay-in section, conveys a medium to be stored in the one or plural medium storage sections to the corresponding one or plural medium storage sections, and that conveys a medium not to be stored in the one or plural medium storage sections to the temporary holding section.
