Image Forming Apparatus Removable Front Cover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses pose difficulties for operators, especially those with disabilities or of varying heights, in performing maintenance and cartridge replacement due to limited access and complex opening mechanisms, which can increase costs and design complexities.
Innovation Solution
The image forming apparatus incorporates a removable front cover supported on a manual feed unit, sharing an opening/closing mechanism with the manual feed unit, allowing easier access from the lower side and simplifying the design by reducing the number of mechanisms and potential errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate robust opening/closing mechanism is provided for the front cover, then the front cover can be opened independently for maintenance access, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the front cover opening/closing mechanism with the manual feed unit opening/closing mechanism into a single integrated system. The first opening/closing member (front cover) and second opening/closing member (manual feed unit) are linked through a shared mechanism that uses one operation to open both components simultaneously, eliminating the need for separate robust mechanisms while maintaining independent accessibility when needed
2Ease of operation
If a separate robust opening/closing mechanism is provided for the front cover, then the front cover can be opened independently for maintenance access, but the manufacturing costs increase
Solution Approach 1:
By merging the front cover mechanism with the manual feed unit mechanism, the patent reduces the total number of mechanical components that need to be manufactured and assembled. This integration lowers manufacturing costs while preserving the ability to open the front cover for maintenance when the manual feed unit is in the received position
3Device complexity
If the front cover is fixed to the body, then the structure is simplified, but the accessibility for operators of varying heights and disabilities is reduced
Solution Approach 1:
The patent implements a dynamic configuration where the front cover's state (fixed or movable) changes based on the position of the manual feed unit. When the manual feed unit is in the received position, the front cover can be opened independently; when the manual feed unit is in the manual feed position, the front cover moves with it. This dynamic behavior provides accessibility when needed while maintaining structural simplicity through the integrated design

AI summary
An image forming apparatus includes: a first opening/closing member that can move between a first opening position in which the first opening/closing member opens an inside of a body of the image forming apparatus, and a first closing position in which the first opening/closing member closes the inside of the body of the image forming apparatus; a second opening/closing member that can move around a rotation shaft and between a second closing position in which the second opening/closing member closes an opening formed in the first opening/closing member, and a second opening position in which the second opening/closing member opens the opening, the second opening/closing member being removably attached to the body of the image forming apparatus; and a supported portion that is provided in the first opening/closing member so as to be supported on a support portion of the second opening/closing member, as defined herein.
