Sheet Decolorizing Device with Selective Post-Process Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decolorizing devices require image reading before and after the decolorizing process, leading to increased time for completing the series of decolorizing processes due to the need for both image data saving and determination of undecolorized portions.
Innovation Solution
A decolorizing device with a transferring section, a first reading section, a decolorizing section, and a second reading section, where the controller determines if the decolorizing process is necessary based on initial image data, allowing for selective reading after the process to avoid unnecessary reading and shorten analysis and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image reading is performed both before and after the decolorizing process, then image data can be saved and undecolorized portions can be determined, but the time to complete the decolorizing process increases
Solution Approach 1:
The controller performs preliminary determination of whether decolorizing is necessary by analyzing image data obtained before the decolorizing process. This preliminary action allows the system to avoid unnecessary post-process reading and undecolorized portion determination, thereby reducing overall processing time while maintaining reliable image data saving and accurate undecolorized portion detection when needed.
2Reliability
If image reading is performed before and after the decolorizing process, then complete image data saving and undecolorized portion determination are achieved, but processing efficiency decreases

Implementation Method 1
a decolorizing section configured to perform a decolorizing process on the sheet
Implementation Method 2
subjecting the sheet including the image formed thereon with a decolorable colorant to a decolorizing process such as heating so as to turn the decolorable colorant in a colored state into a decolorized state

AI summary
According to an embodiment, a decolorizing section is placed on a downstream side of a first reading section in a sheet transferring direction. A second reading section is placed on a downstream side of the decolorizing section in the sheet transferring direction. A controller is configured to determine if the decolorizing process is necessary or not on a first side of a sheet based on first image data of the first side read by the first reading section, to read the first side of the sheet having been subjected to the decolorizing process at the decolorizing section by the second reading section if it is determined that the decolorizing process is necessary, and to avoid reading of the first side of the sheet passed through the decolorizing section by the second reading section if it is determined that the decolorizing process is unnecessary.
