Bill Processing Sensor Detects Open/Close Member Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bill processing apparatuses, such as those described in Patent Document 1, face issues with the upper casing not being sufficiently mounted to the lower casing, leading to potential jamming of bills and inefficiencies in the conveyance mechanism.
Innovation Solution
A paper sheet processing apparatus is designed with an open/close member that can be closed over a frame to form a traveling route for the paper sheet, equipped with sensors to detect when the open/close member is released from the frame, ensuring reliable closure and preventing jamming. This apparatus includes a detection mechanism using a sensor and a detecting member to verify the closed state, and a control system to manage the conveyance and authenticity judgment processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper casing is made freely mountable-and-demountable for ease of maintenance, then the ease of operation is improved, but the reliability deteriorates due to insufficient mounting
Solution Approach 1:
The patent employs a sensor to detect whether the upper casing is properly mounted on the lower casing. This feedback mechanism ensures that the system can verify the mounting state and prevent operation when mounting is insufficient, thereby resolving the contradiction between ease of maintenance and mounting reliability.
2Ease of repair
If the traveling route is exposed outside by turning the upper casing, then the ease of maintenance is improved, but the reliability deteriorates due to potential insufficient mounting
Solution Approach 1:
The sensor detects the mounting state of the upper casing before allowing the traveling route to be exposed. This feedback ensures that the casing is properly mounted before maintenance access is granted, preventing reliability issues while maintaining ease of repair.
3Ease of operation
If the open/close member is made rotatable for ease of access, then the ease of operation is improved, but the reliability deteriorates due to insufficient closure detection
Solution Approach 1:
The sensor provides feedback on the closure state of the open/close member, ensuring that proper closure is detected and verified before the system operates. This resolves the contradiction by maintaining accessibility while ensuring closure reliability through detection.

AI summary
A paper sheet processing apparatus capable of preventing paper sheet clogging in a traveling route in which a paper sheet is conveyed is provided. The paper sheet processing apparatus comprises an open/close member 2B which is opened or closed with respect to a frame 2A and a traveling route through which the paper sheet (a bill, a card, a coupon ticket, and the like are collectively referred to as “paper sheet”) is conveyed is formed between the open/close member 2B and the frame 2A when the open/close member 2B is closed with respect to the frame 2A. The open/close member 2B is provided with a sensor 31 for detecting that the open/close member 2B is opened from the frame 2A.
