Scanner Glass Stain Detection via Displayed Device Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in identifying and removing dust stains from the glass plate of a scanner, as existing technologies do not provide clear indication of the stained area, increasing the burden on users to clean the glass plate effectively.
Innovation Solution
A reading device with a control section that performs stain detection processing by comparing brightness levels from a line sensor and displays a device image on a display section, highlighting the stained region in a specific form, allowing users to accurately locate and clean the stains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If stain detection processing is performed and notification is provided to users, then users can be aware of dust particles on the glass plate, but users cannot identify the specific location of stains, increasing the burden on users to clean the glass plate
Solution Approach 1:
The patent creates a visual copy (device image) of the glass plate and its surrounding components, displaying it on a screen. This copy includes the actual glass plate, cover, and other components in their spatial relationship, allowing users to locate stains by viewing the displayed image rather than physically inspecting the glass plate.
Solution Approach 2:
The patent transitions from direct physical inspection of the glass plate to a two-dimensional displayed image representation. By projecting the three-dimensional spatial arrangement onto a two-dimensional display, users can view the entire glass plate and surrounding components simultaneously, making stain location identification easier.
2Reliability
If the entire glass plate is cleaned to remove all possible stains, then cleaning effectiveness is improved, but time and effort required for cleaning increases
Solution Approach 1:
The patent enables users to identify specific local areas (stain locations) on the glass plate through the displayed device image. Users can then apply cleaning efforts locally to only the stained areas rather than cleaning the entire glass plate surface, improving efficiency while maintaining cleaning effectiveness.
Solution Approach 2:
The patent performs stain detection and displays the device image with stain locations identified before the user begins cleaning. This preliminary identification of problem areas allows users to prepare targeted cleaning actions, avoiding unnecessary cleaning of already clean areas and reducing overall cleaning time.
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
Enables users to concretely and accurately identify and remove stains from the glass plates, reducing the effort required for cleaning and improving the efficiency of the scanning process.
Implementation Method 1
a reading section that is provided to correspond to the glass plate and performs reading by receiving light through the glass plate

AI summary
A reading device includes a main body section, a cover configured to be opened and closed with respect to the main body section, a transport path constructed by the main body section and the cover, a roller that transports an original document, a glass plate arranged on the transport path, and a reading section that performs reading by receiving light through the glass plate, a display section, and a control section, and the control section causes the display section to display a device image in which a stain corresponding region corresponding to a position of the stain on the glass plate is specified in a glass plate image region expressing the glass plate, the device image being an image depicting the reading device in a state where the cover is opened and a configuration including a part of the transport path, the roller, and the glass plate is exposed.
