Pivotally Mounted Support Tray for Compact Paper Cassette
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet cassettes with integrated discharged paper receiving portions increase the height of recording apparatuses, as they require an inclined support surface to prevent paper slipping, which complicates cassette design and increases overall height.
Innovation Solution
A medium receiving cassette with a pivotally mounted support tray that can switch between a received state with a downward-facing surface and an expanded state with an upward-facing surface, allowing the tray to protrude and form an inclined surface to prevent paper slipping, thus maintaining a lower cassette height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharged paper receiving portion is provided in the paper sheet cassette with an inclined support surface, then the paper sheet can be prevented from slipping off, but the height of the paper sheet cassette increases
Solution Approach 1:
The support tray is designed to be movable between a received state (flush with the cassette) and an expanded state (protruding with inclined surface). This dynamic configuration allows the tray to provide an inclined support surface for paper stability only when needed, while maintaining a compact profile during normal operation, thus resolving the contradiction between preventing paper slipping and minimizing cassette height
Solution Approach 2:
The support function is separated from the main cassette body by providing a distinct, movable support tray. This segmented design allows the inclined surface to be deployed independently when paper support is required, without permanently increasing the cassette height structure, thereby resolving the contradiction between paper stability and compact dimensions

AI summary
Provided is a medium receiving cassette that includes a medium receiving portion in which a medium is received, and a medium support tray which is pivotally provided on the medium receiving portion and of which a state can be switched, in a pivoting manner, between a received state in which the medium support tray is positioned above the medium receiving portion and a medium support surface for supporting the medium is directed downward and an expanded state in which the medium support surface is directed upward and at least a part of the medium support surface is expanded outside the medium receiving portion.
