Integrated Bill Insertion Slot Frame Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill processing apparatuses often cause bills to get stuck in the insertion slot, leading to bending and difficulty in insertion due to gaps between frame components.
Innovation Solution
A paper sheet processing apparatus with an open/close member and frame members forming a seamless insertion slot, featuring vertical and horizontal frame pieces that guide the bill without seams, preventing sticking and facilitating easy insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate frame components are used to form the insertion slot, then the structure is easier to manufacture and assemble, but gaps between components cause bills to get stuck and bend
Solution Approach 1:
The patent merges multiple separate frame components (upright portions and plate) into a single integrated frame structure. This eliminates the gaps between components that caused bills to get stuck and bend during insertion, while maintaining the structural functionality of guiding and supporting the bill through the insertion slot.
2Ease of operation
If a plate is installed between upright portions to form the insertion slot, then the slot structure is defined, but gaps between the plate and upright portions cause bills to stick
Solution Approach 1:
The patent combines the plate and upright portions into a single integrated frame structure, eliminating gaps between these components. This provides a seamless surface for bill insertion without the sticking problems caused by gaps, while the integrated structure actually simplifies the overall frame design compared to assembling multiple separate components.

AI summary
A paper sheet processing apparatus allowing easy insertion of a paper sheet such as a bill into an insertion slot is provided, although it is difficult to push the paper sheet for insertion because it is easily bent. The bill processing apparatus according to the present invention includes: an open/close member to be opened and closed with respect to a frame; a bill insertion slot formed such that a bill is capable of being inserted therebetween when the open/close member is closed with respect to the frame; a frame member mounted to the bill insertion opening and having a vertical frame piece along a thickness direction of the bill insertion slot and a horizontal frame piece along a lateral direction formed integrally with each other.
