Movable Sheet Feeding Layout for Copier Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a large-capacity feeding device with a manual feeding device in image forming apparatuses leads to interference during maintenance, making it difficult to secure a sufficient working space due to the protrusion of the manual feed tray when the door is opened.
Innovation Solution
The large-capacity feeding device is designed to be movable horizontally between coupled and decoupled positions, allowing the door to open fully without interference from the manual feed tray, and includes a guide unit and cover to facilitate easy movement and maintain a safe working space during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the manual feed tray protrudes outward from the side surface of the apparatus main body, then the workability of maintenance is reduced, but the feeding function of special sheets is improved
Solution Approach 1:
The manual feed tray is designed to be movable between a protruding state (when the door is closed) and a retracted state (when the door is opened). This dynamic configuration allows the tray to adapt its position based on operational requirements, resolving the contradiction between maintaining feeding functionality and ensuring maintenance accessibility.
2Quantity of substance
If the large-capacity feeding device is coupled to the manual feeding device, then the sheet feeding capacity is improved, but the working space during maintenance is reduced
Solution Approach 1:
The feeding system is divided into two independent components: a large-capacity feeding device and a manual feeding device. The large-capacity device can be coupled or decoupled from the manual feeding device, allowing the working space to be adjusted based on maintenance requirements while maintaining sheet feeding capacity.
3Area of stationary object
If the manual feed tray is removed from the device body, then the working space during maintenance is improved, but the workability of maintenance is reduced
Solution Approach 1:
The manual feed tray is designed to be movable between a protruding state (when the door is closed) and a retracted state (when the door is opened). This dynamic configuration allows the tray to adapt its position based on operational requirements, resolving the contradiction between maintaining feeding functionality and ensuring maintenance accessibility.

AI summary
An image forming system includes an image forming apparatus and a feeding device, the image forming apparatus including an image forming unit, a housing, an opening/closing door openable and closable between a first closed position and a first open position, and a support unit openable and closable between a second closed position and a second open position and configured to support a sheet when the support unit is at the second open position, the feeding device being movable in a direction horizontal to the image forming apparatus, configured to move to a coupled position and a decoupled position and feed the sheet to the image forming apparatus when the feeding device is at the coupled position, wherein when the feeding device is at the decoupled position and the opening/closing door is at the first open position, the feeding device overlaps the support unit as viewed from a first direction.
