Recording Apparatus Unit Body Displacement for Jam Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face difficulties in paper jam release due to complex configurations and the need to detach the bending inversion unit, which can lead to reduced workability and risk of paper tearing.
Innovation Solution
A recording apparatus with a unit body that is attachable and detachable, featuring a feeding roller and a driven roller, allowing displacement between connected and separated positions, enabling easy paper jam release by disconnecting the drive force transmission, and a retention unit to prevent unintentional movement, along with an openable and closeable cover for enhanced accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bending inversion unit is detached to expose the paper transportation path, then paper jam release becomes possible, but the workability deteriorates due to the need to detach the unit
Solution Approach 1:
The recording apparatus is divided into a main body and a detachable unit body. The unit body can be quickly separated from the main body to expose the paper transportation path, allowing users to access and remove jammed paper without detaching the entire apparatus. This segmentation enables rapid paper jam release while maintaining the compact structure of the complete device.
2Ease of operation
If the unit body is made detachable to simplify paper jam release, then accessibility is improved, but the configuration complexity increases
Solution Approach 1:
The recording apparatus is divided into a main body and a detachable unit body. The unit body can be quickly separated from the main body to expose the paper transportation path, allowing users to access and remove jammed paper without detaching the entire apparatus. This segmentation enables rapid paper jam release while maintaining the compact structure of the complete device.
3Ease of operation
If the driven transmission unit remains connected during paper jam release, then the structure remains compact, but the feeding roller cannot rotate freely making paper removal difficult
Solution Approach 1:
The unit body is designed to be dynamically reconfigurable, allowing it to switch between a connected state (where the driven transmission unit is engaged with the drive transmission unit) and a disconnected state (where the unit body is pulled out and the driven transmission unit is separated). This dynamic adjustment enables the feeding roller to rotate freely when needed for paper removal, while maintaining a compact integrated structure during normal operation.

AI summary
A recording apparatus includes a apparatus main body, and a unit body that forms a medium transportation path, and is configured to be attachable and detachable with respect to the apparatus main body. The unit body includes a feeding roller that transports a medium, and a driven transportation unit that transmits the drive force of the drive transportation unit to the feeding roller. The unit body is displaceable between a first position at which the driven transmission unit is connected to the drive transmission unit and a second position at which the driven transmission unit is separated from the drive transmission unit. When a user pulls out the medium, the unit body retained at the first position moves from the first position to the second position.
