Code Reading Device Visual Decoding Status Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing code reading devices struggle to easily identify and distinguish between successfully decoded and non-decoded code patterns when reading multiple codes simultaneously, leading to potential misidentification of correspondence between code patterns and their decoding results.
Innovation Solution
A code reading device and program that include a decoding processor to determine successful decoding of each code pattern and a display device to show the determination result, along with identifying marks, allowing users to select which code patterns are decoding targets and displaying decoding results accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all code patterns in the image data are decoded, then the reading completeness is improved, but the possibility of misidentifying the correspondence between code pattern and decoding result increases
Solution Approach 1:
The patent segments the batch of code patterns into individual units, each with its own decoding status and visual indicator. By dividing the collective decoding process into discrete, trackable units, the system maintains reading completeness while enabling precise identification of each code pattern's decoding status through separate visual markers.
Solution Approach 2:
The patent implements a feedback mechanism by providing real-time visual indicators (checkmarks for successful decoding, crosses for failed decoding) that immediately inform the user of each code pattern's decoding status. This feedback loop prevents misidentification by making the correspondence between code patterns and their decoding results explicitly visible.
2Productivity
If multiple code patterns are read at a time, then the workability is improved, but the difficulty of confirming successful decoding increases
Solution Approach 1:
The patent employs visual indicators that change appearance based on decoding status - checkmarks for successful decoding and crosses for failed decoding. These distinct visual symbols provide immediate, easy-to-distinguish feedback that simplifies the confirmation process while maintaining the ability to read multiple code patterns simultaneously.
Solution Approach 2:
The patent adds a visual dimension to the decoding status information by displaying checkmarks and crosses alongside or near the corresponding code patterns. This dimensional addition transforms abstract decoding results into visually perceptible indicators, making it easy to confirm successful decoding even when multiple patterns are processed at once.
3Reliability
If code patterns that are not to be read are included in the decoding process, then the reading completeness is improved, but the accuracy of identifying desired decoding targets decreases
Solution Approach 1:
The patent segments each code pattern with its own visual indicator, allowing users to distinguish between code patterns that are decoding targets and those that are not. By providing individual visual feedback for each pattern, the system maintains complete reading while enabling precise identification of which patterns were intentionally decoded versus which were not.

AI summary
On a display window that displays code patterns that are read at a time, a code reading device allows the code pattern that is successfully decoded to be visually confirmed with ease. In a handy terminal, when an image scanner reads code patterns at a time in response to a trigger operation, a CPU performs decoding processes for each code pattern and determines whether the decoding processes have been successfully completed or not based on the decoding results so as to display an identifying mark indicating the determination result in association with the image of each code pattern.
