Post-processing Device Recording Medium Alignment Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-processing devices face issues with abutting one end of a freely bendable recording medium against a supporting section, as the medium may bend and prevent successful contact, leading to trouble in alignment and processing.
Innovation Solution
A post-processing device with a loading section, a supporting section, a restricting section that contacts the recording medium to prevent bending, and an abutting section that pushes the upper end of the recording medium downward to align it with the supporting section, ensuring proper alignment and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the recording medium is made freely bendable for easy loading, then the ease of operation is improved, but the reliability of abutting one end against the supporting section deteriorates due to bending
Solution Approach 1:
The restricting section is positioned to contact the recording medium before the abutting section pushes the medium against the supporting section. This preliminary action prevents bending from occurring during the subsequent abutting operation, ensuring reliable positioning while maintaining easy loading capabilities
2Manufacturing precision
If the abutting section pushes the upper end downward to align the recording medium, then the manufacturing precision of alignment is improved, but the device complexity increases due to additional sections
Solution Approach 1:
The post-processing device is divided into distinct functional sections: a loading section for easy medium placement, a restricting section to prevent bending, and an abutting section for precise alignment. This segmentation allows each component to perform its specific function efficiently, achieving high alignment precision through the coordinated action of simple, dedicated sections
3Reliability
If the restricting section contacts the recording medium to prevent bending, then the reliability of the abutting process is improved, but the ease of operation deteriorates due to additional constraints
Solution Approach 1:
The restricting section is designed to contact only the specific portion of the recording medium that requires bending prevention, rather than constraining the entire medium. This localized constraint prevents bending at the critical area while leaving other portions free, maintaining ease of loading operations

AI summary
A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a restricting section that restricts bending of the recording medium by coming into contact with the recording medium loaded on the loading surface; and an abutting section that abuts the one end of the recording medium against the supporting section by pushing an upper end of the recording medium opposite to the one end downward, in a state where the restricting section restricts the bending of the recording medium.
