Recording Device Restricting Wall for Imaging Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recording devices face issues with mist and paper dust adhering to imaging mechanisms, which impede accurate capture of recording statuses on mediums during the recording and cutting processes.
Innovation Solution
A recording device configuration that includes a restricting wall narrowing the space above the transport path between the recording unit and the imaging unit, inhibiting the adhesion of mist and paper dust, allowing for accurate image capture of recorded mediums.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an imaging mechanism is added to capture recording status, then recording quality monitoring is improved, but measurement precision deteriorates due to mist and paper dust adhering to the imaging mechanism
Solution Approach 1:
The transport path is divided into multiple sections with restricting walls creating separate spaces. The imaging unit operates in a restricted space that is separated from the recording unit's mist generation zone and the cutting unit's dust generation zone, allowing clean image capture without contamination from foreign materials
Solution Approach 2:
Restricting walls act as intermediary structures that physically separate the imaging unit from sources of contamination (mist from recording unit, dust from cutting unit). These walls create protective barriers that prevent foreign materials from reaching the imaging mechanism while still allowing the transport path to function
2Reliability
If the transport path space is reduced to control foreign materials, then reliability is improved by preventing adhesion, but device complexity increases due to adding restricting walls
Solution Approach 1:
The transport path is segmented into multiple sections by restricting walls, creating distinct functional zones. This segmentation isolates the imaging unit in a clean environment while maintaining the overall transport function, improving reliability without requiring complete redesign of the entire transport system
Solution Approach 2:
Restricting walls are strategically placed only in specific locations where foreign material contamination is most problematic (between imaging unit and recording/cutting units). This localized approach creates clean zones exactly where needed without adding unnecessary structural complexity to the entire transport path

AI summary
A recording device includes: a storage unit configured to store a medium, a recording unit configured to dispense a liquid droplet onto the medium transported from the storage unit to perform recording, a discharge unit configured to discharge the medium on which recording was performed and an imaging unit disposed on a transport path running from the storage unit, past the recording unit, to the discharge unit, the imaging unit being configured to capture an image of the medium on which recording was performed, where a restricting wall narrowing a space above the medium on the transport path is provided between the recording unit and the imaging unit.
