Barcode Recording Apparatus Dynamic Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers face productivity losses when recording barcodes or two-dimensional codes at high grades due to restrictions on inkjet head driving frequency and sheet conveying speed, even if lower-grade barcodes can be read without issues, leading to unnecessary reductions in productivity.
Innovation Solution
A recording apparatus with a liquid ejection head, controller, and user-input settings for barcode or two-dimensional code grades, allowing the printer to adjust ejection speed and droplet volume based on user-defined settings to optimize grade and productivity by switching between high and low grade modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the inkjet head driving frequency is reduced to record high-grade barcodes, then the barcode grade is improved, but the productivity deteriorates
Solution Approach 1:
The patent applies dynamics by making the inkjet head driving frequency adjustable rather than fixed. The controller dynamically changes the driving frequency based on the selected grade setting, allowing the system to adapt between high precision (low frequency) and high productivity (high frequency) modes as needed
2Manufacturing precision
If the sheet conveying speed is reduced to record high-grade barcodes, then the barcode grade is improved, but the productivity deteriorates
Solution Approach 1:
The patent applies dynamics by making the sheet conveying speed adjustable rather than fixed. The controller dynamically adjusts the conveying speed based on the selected grade setting, enabling the system to operate at lower speeds for high-grade recordings and higher speeds for lower-grade recordings that still meet readability requirements
3Productivity
If the ejection speed is adjusted to optimize productivity, then the productivity is improved, but the barcode grade deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting the ejection speed parameter based on the selected grade setting. The controller modifies this physical parameter to match the desired output quality, allowing flexible optimization between productivity and barcode grade depending on the specific application requirements

AI summary
A recording apparatus includes a liquid ejection head having nozzles, a controller, and a signal input part through which a user inputs, to the controller, a setting signal indicating settings related to a grade of a barcode or two-dimensional code. The controller drives the liquid ejection head based on the setting signal input through the signal input part to cause the nozzles to eject liquid to record a barcode or two-dimensional code on a recording medium in the grade corresponding to the setting signal.
