Reading Apparatus Body Height Positioning via Convex Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading apparatuses face challenges in accurately positioning and securely mounting the reading apparatus body relative to the document platen, particularly in maintaining alignment and preventing the reading apparatus body from falling during manufacturing and use.
Innovation Solution
The image reading apparatus incorporates a spacer with convex sections and an engaging section that uses coil springs and a guide member to position and secure the reading apparatus body, ensuring accurate height alignment and preventing it from falling by engaging with the accommodation member, while minimizing the risk of material deformation or cracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the reading apparatus body is mounted on the document platen using existing methods, then it can be positioned and secured, but it is difficult to accurately position it in the height direction and prevent it from falling during manufacturing and use
Solution Approach 1:
The patent introduces a positioning member as an intermediary component between the reading apparatus body and the document platen. This positioning member includes a convex section that contacts the document platen and an engaging section that engages with the accommodation member, thereby mediating the positioning and securing functions to achieve both accurate height positioning and fall prevention
Solution Approach 2:
The positioning member is nested within the accommodation member structure, with the engaging section fitting into a groove formed in the accommodation member. This nested configuration allows the positioning member to be integrated into the existing structure while providing the necessary positioning and securing functions
2Reliability
If a secure mounting structure is used to prevent the reading apparatus body from falling, then reliability improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into the positioning member: it serves as both a positioning element (convex section contacting the document platen) and a securing element (engaging section engaging with the accommodation member). This merging of functions achieves reliable fall prevention without requiring multiple separate components, thereby avoiding increased device complexity
3Reliability
If the reading apparatus body is securely fixed to prevent falling, then reliability improves, but ease of replacement of components deteriorates
Solution Approach 1:
The positioning member is designed as a separate, modular component that can be independently assembled and disassembled. The engaging section fits into a groove in the accommodation member, allowing the positioning member to be easily removed and replaced without affecting other components, thus maintaining ease of repair while providing secure mounting

AI summary
An image reading apparatus includes a reading apparatus body, an accommodation member, and a positioning member. The reading apparatus body reads a document mounted on a document platen. The accommodation member accommodates the reading apparatus body and moves from one end portion to the other end portion of the document when reading the document. The positioning member is mounted on the reading apparatus body, the positioning member having a convex section positioning the reading apparatus body in a height direction by coming into contact with the document platen and an engaging section engaging with an engaged section formed in the accommodation member in the height direction.
