Image Forming Device Cut Line Curving Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming devices struggle to form cut lines on recording media that are easily removable, as the cut line formation is uniform and does not consider the properties of the recording medium, leading to difficulties in cutting out main images.
Innovation Solution
An image forming device that includes a line information generation unit to create line information for a cut line and an image forming unit to form the main image with a non-decolorable material and the cut line with a decolorable material, with the ability to adjust the level of curving of the cut line based on the recording medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cut line is uniformly formed without considering the recording medium properties, then the formation process is simple, but the main image cannot be easily cut out depending on the recording medium
Solution Approach 1:
The patent applies local quality by adjusting the curving level of the cut line according to the specific recording medium being used. Different recording media (e.g., thick sheets, hard sheets, transparent sheets) receive different curving level settings, making the cut line formation process adapted to local medium properties rather than applying a uniform approach to all media types.
Solution Approach 2:
The patent implements dynamics by making the curving level of the cut line adjustable and changeable based on the recording medium. The system allows dynamic modification of the cut line parameters before formation, enabling the user to select appropriate curving levels (e.g., gentle curving for thick/hard sheets, normal curving for standard sheets) to optimize cutting ease for each specific medium type.
2Ease of operation
If the curving level of the cut line is increased for thick or hard sheets, then it becomes easier to cut out the main image, but the cut line formation becomes more complex
Solution Approach 1:
The patent applies preliminary action by allowing the user to pre-select the appropriate curving level based on the recording medium type before the cut line is formed. The system provides a selection interface where users can choose from different curving level options (gentle, normal, etc.) corresponding to different medium types, and this selection is stored and applied automatically during cut line formation, eliminating the need for complex real-time adjustments.
3Ease of operation
If the cut line is formed with a decolorable material, then the cut line can be removed after cutting, but the cut line may not be visible enough on certain recording media
Solution Approach 1:
The patent applies parameter changes by modifying the visual parameters of the cut line (curving level) to enhance visibility on different recording media types. By adjusting the curving level parameter based on the medium properties (e.g., transparency, thickness), the system optimizes the cut line's visibility while maintaining the decolorable material property that allows for easy removal after cutting.

AI summary
Provided is a technique that can suitably form a cut line. According to one embodiment, an image forming device includes a line information generation unit and an image forming unit. The line information generation unit generates line information representing a cut line to cut out a main image formed on a recording medium. The image forming unit forms the main image with a non-decolorable material on the recording medium and forms the cut line represented by the line information with a decolorable material on the recording medium. The line information generation unit changes a level of curving of a curve included in the cut line, according to the recording medium.
