Decoloring Apparatus Error Recovery and Image Data Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In decoloring apparatuses, if the reading operation is stopped due to an error before the paper is fully read, parts of the paper may be decolored, leading to incomplete image data storage and incorrect paper handling.
Innovation Solution
A decoloring apparatus with a control section that resumes the reading process after an error is resolved, allowing the remaining image data to be read and combined with previously stored data, ensuring complete image data generation and correct paper handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reading operation is stopped due to an error before the paper is fully read, then the reading process is interrupted, but part of the paper is decolored and the paper cannot be stored correctly
Solution Approach 1:
The control section stores the read position information before an error occurs, allowing the reading operation to resume from the correct position after error resolution rather than re-reading the entire document or leaving data incomplete
Solution Approach 2:
The system implements feedback by detecting reading errors, storing the current read position, and using this information to control the resumption of the reading operation, ensuring that the reading process continues from where it left off
2Reliability
If the reading operation is stopped due to an error, then the reading process is interrupted, but the paper position in the conveyance path causes partial decoloring
Solution Approach 1:
The control section stores the read position information before an error occurs, allowing the reading operation to resume from the correct position after error resolution rather than re-reading the entire document or leaving data incomplete
Solution Approach 2:
The system implements feedback by detecting reading errors, storing the current read position, and using this information to control the resumption of the reading operation, ensuring that the reading process continues from where it left off
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
Ensures complete image data recovery and accurate paper handling even when errors occur, allowing for the reuse of partially decolored paper, contributing to the downsizing of the apparatus and addressing reading errors beyond paper jams.
Implementation Method 1
a reading section positioned on the conveyance path and configured to read the image formed on the sheet and to generate image data corresponding to the read image
Implementation Method 2
a decoloring section positioned on the conveyance path downstream of the reading section in a document conveying direction and configured to decolor the image formed on the sheet
Data Source
AI summary
A reading apparatus includes a paper feed section that feeds a sheet on which an image is formed with decolorable material to a conveyance path. A reading section positioned on the conveyance path reads the image formed on the sheet and generates image data corresponding to the read image. A paper discharge section discharges the sheet after the reading section has read the image. If the reading section reads a portion of the image formed on the sheet due to an error, the sheet is conveyed to the reading section again to read a remainder portion of the image that was not initially read in the reading section and to generate image data corresponding to the remainder portion of the image. The image data corresponding to the read portion of the image is combined with the image data corresponding to the remainder portion of the image.
