Modular Erasing Apparatus Sliding Feeder Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses lack the ability to diversify sheet supply means to the printer device when using an erasing unit, as the erasing unit cannot supply sheets individually and integrating feeder and erasing units complicates maintenance and paper jam clearance.
Innovation Solution
An erasing apparatus with a first sheet stack and erasing device, housed in a casing that supports both components slidably, allowing them to move in and out, and connects with the image forming apparatus's conveying paths to supply erased sheets, while also functioning as a feeder unit, enabling the erasing unit to be used as an optional addition to the image forming apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the erasing unit is integrated with the feeder unit in one dedicated casing, then the sheet supply means is diversified, but the maintenance complexity and paper jam clearance difficulty increase
Solution Approach 1:
The patent divides the integrated unit into separable components: the erasing unit (with heating device) and the feeder unit (with paper cassettes) can be detached from each other while remaining within the same dedicated casing. This segmentation allows independent maintenance of each component without disassembling the entire system, resolving the contradiction between integration benefits and maintenance complexity.
2Reliability
If the erasing unit is connected to supply erased sheets to the feeder unit, then the erasing function is achieved, but the ability to supply sheets to the printer device directly is lost
Solution Approach 1:
The erasing unit is designed with dual functionality: it can process sheets through the erasing device and supply them to the feeder unit, while also having the capability to supply erased sheets directly to the printer device. This multi-functionality resolves the contradiction by allowing the unit to adapt to different operational modes based on system requirements.
3Area of stationary object
If the dedicated casing of the erasing unit is connected to the main casing in place of the feeder unit, then space is optimized, but the erasing unit cannot supply sheets to the printer device
Solution Approach 1:
The patent implements a dynamic connection system where the dedicated casing of the erasing unit can be selectively connected to different positions on the main casing. The connection interface allows the erasing unit to be positioned to supply sheets to either the feeder unit or directly to the printer device, providing operational flexibility while maintaining space optimization.
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
Enables the erasing unit to function as both an erasing and feeder unit, allowing for efficient supply of sheets to the printer device and simplifying maintenance by allowing individual components to be removed and reinserted, maintaining the erasing device's temperature and preventing accidental contact with its heat sources.
Implementation Method 1
the apparatus heats an image printed on a sheet with an erasable toner or the like at a predetermined erasing temperature, for example, and thereby erases the image

AI summary
An image forming apparatus according to an embodiment includes a feeder unit that stores a sheet on which no image is formed. A printer device forms an image on the sheet stored by the feeder unit. An erasing apparatus is connectably and detachably attached to the image forming apparatus. The erasing apparatus includes a first sheet stack that stores an unerased sheet on which an image is formed and an erasing device that erases the image formed on the unerased sheet.
