Sheet Storing Apparatus Manual Insertion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet storing apparatuses face instability issues during manual insertion due to rattling at open-close hinges, affecting the positioning of sheets for binding processes.
Innovation Solution
A sheet storing apparatus with a manual setting portion featuring a slit-shaped opening, a setting face, and an abutting-regulating face to stabilize sheet bundles, preventing accidental insertion and ensuring correct positioning despite open-close cover rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an openable-closable open-close cover is arranged at the manual insertion portion, then accessibility and safety are improved, but sheet positioning stability deteriorates due to rattling at the open-close hinge portion
Solution Approach 1:
A buffer member is introduced as an intermediary element between the open-close cover and the setting face. This buffer member absorbs the rattling movements generated by the open-close hinge, preventing them from transmitting to the sheet bundle during insertion. The buffer member acts as a mediator that isolates the unstable cover movement from the sheets, maintaining positioning stability while preserving the openable-closable functionality.
2Ease of operation
If the opening at the open-close cover is made larger, then ease of insertion is improved, but accidental insertion of foreign objects increases
Solution Approach 1:
The opening at the open-close cover is designed with non-uniform dimensions - the width is sufficiently large to allow easy insertion of sheet bundles, while the height is restricted to a smaller dimension that prevents foreign objects from being accidentally inserted. This local quality differentiation in the opening geometry allows the system to simultaneously achieve ease of operation and protection against harmful factors.
3Device complexity
If the manual setting portion is integrated into the open-close cover, then device complexity is reduced, but positioning precision deteriorates due to cover rattling
Solution Approach 1:
The buffer member serves as an intermediary that decouples the structural integration of the setting face with the open-close cover from the positioning function. By introducing this intermediate element, the system maintains the simplified integrated structure while preventing rattling transmission, thereby preserving positioning precision without increasing overall device complexity.

AI summary
To provide an apparatus capable of stably performing a binding process on a sheet bundle which is set from the outside as having a setting portion arranged at an external cover of a sheet storing apparatus. In an apparatus including a setting portion arranged at an external cover as being capable of setting a sheet bundle from the outside, the setting portion includes a opening, a setting face on which sheets inserted through the opening are placed, and an abutting-regulating face which performs positioning of end edges of the sheets inserted, the opening is arranged at an open-close cover of the external cover, and the abutting-regulating face are arranged at an apparatus frame which is located at the inner side of the open-close cover.
