Optical Reader Extending Portion Window for Barcode Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical information readers struggle to allow users to visually confirm the position of information codes, such as barcodes, especially when they are large or positioned in a way that obstructs the reading opening, leading to unreliable reading processes, particularly with two-dimensional codes.
Innovation Solution
The optical information reader features a peripheral extending portion with an opened portion that allows the user's line of sight to pass through, enabling visual confirmation of the information code's position without adding specific shapes or materials, simplifying the structure and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reading opening is placed in contact with or close to the information code to ensure reliable reading, then the reading reliability is improved, but the user cannot see the information code as it becomes hidden behind the reader
Solution Approach 1:
The housing is divided into distinct functional sections: a reading opening section for optical reading, a window portion for visual confirmation, and an extending portion for structural support. This segmentation allows each section to perform its specific function without interfering with others, enabling the user to see the code while maintaining reading reliability.
Solution Approach 2:
The window portion is positioned at a different spatial location than the reading opening, allowing the user to view the information code from a different dimension or angle. The extending portion projects forward to position the reading opening close to the code while the window portion remains accessible for visual confirmation from another viewpoint.
2Device complexity
If a housing configuration is used that serves both as a window portion for viewing and as a light reflection component, then the structure is more integrated, but the range of choices regarding shape and material is limited and the structure becomes more complicated
Solution Approach 1:
The housing is segmented into separate functional components: the window portion for viewing and the side walls for light reflection. This separation allows each component to be optimized independently for its specific function, providing greater flexibility in shape and material selection without compromising structural integration.
Solution Approach 2:
The extending portion serves multiple functions: it provides structural support for the reading opening, creates the necessary spacing for code visibility, and contributes to the overall housing configuration. This multi-functionality achieves structural integration without requiring specialized components with limited design flexibility.

Function Achieved in This Case
This configuration allows users to easily align the information code with the reading opening, improving the success rate of reading operations by providing a clear view of the code's position and size, even when the reader is placed near the code, thus facilitating accurate reading without increasing complexity or components.
Implementation Method 1
a reading opening through which illumination light and reflected light of the illumination light are transmitted

AI summary
An optical information reader includes a main body portion in which a reading opening is formed; and a grip portion that is connected to a section of the main body portion other than a section in which the reading opening is formed, and is gripped by a user. The reader further includes a light-receiving sensor that captures an image of a predetermined imaging area AR through the reading opening; and a control circuit that performs an interpreting process of a code image of an information code imaged by the light-receiving sensor. An extending portion that extends towards the information code side is provided in a periphery of the reading opening. An opened portion is formed in a section of the extending portion other than a section on the grip portion side.
