Rotatable Document Feeder with Sloped Handgrip Depression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document reading devices in image forming apparatuses face challenges in efficiently handling and reading documents of varying sizes, particularly in expanding the space for easy retrieval of discharged recording media, such as postcards, which require manual insertion and retrieval without compromising the operability of the device.
Innovation Solution
A document reading device with a rotatable opening/closing body and a handgrip featuring a depression that slopes inward as it approaches the device main body, allowing for expanded space and improved ergonomics during operation, enhancing the ease of document retrieval and maintaining device operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening/closing body is made rotatable to expand space for document retrieval, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The opening/closing body is designed to be rotatable rather than fixed, allowing dynamic adjustment of the discharge space. This enables the space for document retrieval to be expanded when needed while maintaining a compact configuration during normal operation, thus improving ease of operation without permanently increasing device complexity
Solution Approach 2:
The device is divided into separable components including the opening/closing body that can be independently rotated. This segmentation allows the retrieval space to be expanded by rotating a specific component rather than reconfiguring the entire device, managing complexity through modular design
2Ease of operation
If the handgrip depression slopes inward to improve ergonomics, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The handgrip depression features a localized sloped surface specifically at the contact area for fingers. This local quality change improves ergonomics where it matters most (at the finger contact point) without requiring high precision throughout the entire handgrip structure, thus balancing ease of operation with manufacturability

AI summary
A document reading device includes: a document reading device main body; and an opening/closing body with one end supported rotatably with respect to the document reading device main body while another end openably/closably provided, the other end of the opening/closing body being provided with a handgrip having a depression sloped toward inside of the opening/closing body in accordance with approach of the opening/closing body to the document reading device main body in a closed status with respect to the document reading device main body.
