Color Reference Slice Plane Alignment in Scanning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheetfed scanning apparatuses fail to accurately reveal the optical condition of paper sheets due to misalignment between the color reference slice and the paper sheet's scanning plane, leading to inconsistent scanning results and complex assembly processes.
Innovation Solution
A scanning apparatus design where the color reference slice is fixed on the same plane as the transparent plate facing the paper-feeding track, ensuring that the color reference value accurately reflects the optical condition of the paper sheet, eliminating the need for additional assembly tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the color reference slice is disposed separately from the transparent plate (as in prior art), then the assembly structure is simpler, but the optical condition of the color reference slice differs from that of the paper sheet, leading to inaccurate color correction
Solution Approach 1:
The color reference slice is integrated with the transparent plate by being夹持 on the same side, making them share the same optical path and plane. This merging ensures that both the paper sheet and color reference slice are scanned under identical optical conditions, eliminating the need for separate calibration and improving color accuracy.
Solution Approach 2:
The transparent plate serves as an intermediary that both the paper sheet and color reference slice pass through during scanning. By positioning the color reference slice on the same side of the transparent plate as the paper sheet, the plate mediates the optical interaction for both, ensuring consistent optical conditions.
2Productivity
If the color reference slice is positioned at a different plane than the paper sheet (as in prior art), then the scanning module can capture both, but the optical conditions differ, requiring repeated tests and modification parameters
Solution Approach 1:
The color reference slice and paper sheet are positioned on the same plane during scanning, creating equipotential optical conditions. This means both objects experience identical light paths, angles, and intensities through the transparent plate, eliminating the need for post-processing modification parameters and repeated tests.
3Stability of the object's composition
If additional elements are added to fix the color reference slice and transparent plate separately, then the positioning is more stable, but the assembly becomes more complex and inconvenient
Solution Approach 1:
The fixing mechanism is merged into a single integrated system where the color reference slice and transparent plate are both夹持 on the same side. This unified fixing approach maintains stable positioning for both components while reducing the number of separate fixing elements needed, thereby simplifying the overall assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for direct correction of image data using the color reference slice's value without distortion, simplifying the assembly process and ensuring consistent scanning results across different apparatuses.
Implementation Method 1
a transparent plate made of transparent materials such as glass, and paper sheets moving on the transparent plate are scanned by a scanning module
Implementation Method 2
paper sheets moving on the transparent plate are scanned by a scanning module, so as to produce and then output the image data
Implementation Method 3
a color reference slice is disposed in the scanning apparatus as a color reference, such that when scanning the paper sheets, the scanning module also captures the image of the color reference slice, and then corrects the image data with the color and color level of the color reference slice

AI summary
A scanning apparatus includes a body, a transparent plate, a scanning module, and a color reference slice. A paper-feeding track is formed within the body, and a scanning window is formed at a side wall of the paper-feeding track. A coupling groove is formed at an edge of the scanning window. Both the transparent plate and the color reference slice have an edge being inserted into the coupling groove, such that the transparent plate covers the scanning window while the color reference slice leans against a side surface of the transparent plate facing the paper-feeding track. The scanning module is disposed within the body corresponding to the scanning window, such that a paper to be scanned and the color reference slice are located in the same plane, and the color reference slice and the paper are scanned under the same optical conditions.
