Detachable Storage Module for Jammed Sheet Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet handling apparatuses, such as banknote depositing/dispensing machines, face difficulties in easily removing jammed paper sheets due to restricted access and space constraints, particularly when the storage units are connected with hinges, limiting the exposure of the transport path and hindering the removal process.
Innovation Solution
A paper sheet handling apparatus with a detachable storage module configuration, where the storage module is attachable and detachable from the body via a string-like member, allowing the second transport surface to be exposed widely, enabling easy removal of jammed paper sheets without requiring specific space arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage units are connected with hinges to allow rotation for removing jammed paper sheets, then the apparatus can be opened to access the transport path, but the exposure of the transport path is restricted and space constraints prevent easy removal of jammed sheets
Solution Approach 1:
The storage unit is divided into a first storage unit and a second storage unit that can be separated from each other. The first storage unit remains attached to the apparatus body while the second storage unit is detached and held by the holder, allowing the transport path between them to be fully exposed for easy removal of jammed paper sheets.
Solution Approach 2:
A holder is introduced as an intermediary component to hold the detached second storage unit. This holder allows the second storage unit to be positioned away from the apparatus body, maintaining exposure of the transport path while providing a convenient location for the detached storage unit.
2Ease of operation
If the storage module is made detachable to expose the transport path widely, then easy removal of jammed paper sheets is enabled, but the device complexity increases
Solution Approach 1:
The storage module is segmented into detachable first and second storage units with a defined attachment/detachment interface. This segmentation enables simple attachment and detachment operations without requiring complex mechanisms, as each unit has a dedicated connection point on the apparatus body.
Solution Approach 2:
The attachment interface on the apparatus body serves multiple functions: it attaches the first storage unit during normal operation, provides a mounting point for the holder, and allows easy detachment of the second storage unit for maintenance access, eliminating the need for separate mechanisms for each function.

AI summary
A paper sheet handling apparatus includes: a transport path including a pair of a first transport surface and a second transport surface; at least one storage module configured to store the paper sheets transported through the transport path; and a body including the transport path and the storage module. The storage module is attachable and detachable to and from the body by moving the storage module in a predetermined direction, a part of an outer surface of the storage module attached to the body forms the first transport surface, and the second transport surface is exposed when the storage module is detached from the body so that the second transport surface is visible from the predetermined direction.
