Recording Apparatus Restricting Unit Prevents Roller Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vertical type recording apparatuses, the recording medium held in a standing posture can come into contact with the discharge roller, leading to contamination or damage, and potential paper jams when separated.
Innovation Solution
A recording apparatus with a holding unit that maintains the recorded medium in a standing posture, incorporating a restricting unit to prevent contact with the discharge roller, and a medium intake portion positioned lower than the roller to ensure smooth delivery without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the discharge roller is used to transport the recording medium, then the recording medium can be moved efficiently, but the recording medium may come into contact with the discharge roller and become contaminated or damaged
Solution Approach 1:
A restricting unit is introduced as an intermediary component between the discharge roller and the recording medium. This restricting unit prevents direct contact between the discharge roller and the recording medium while allowing the transport function to continue, thus eliminating contamination and damage without sacrificing transport efficiency
Solution Approach 2:
The holding unit is segmented into a receiving unit and a holding unit, with the receiving unit positioned to receive the recording medium from the discharge roller and the holding unit positioned to hold it in a standing posture. This segmentation separates the transport function from the holding function, preventing contact between the discharge roller and the recorded medium
2Stability of the object's composition
If the holding unit is positioned to hold the recording medium in a standing posture, then the recording medium can be held stably, but the lower end may bend or separate from the holding unit causing contact with the discharge roller
Solution Approach 1:
The restricting unit extends in the vertical dimension to create a physical barrier that prevents the recording medium from bending or separating from the holding unit. By adding this vertical restriction, the system maintains holding stability while preventing the harmful contact dimension
3Device complexity
If the medium intake portion is positioned high to receive the recording medium, then the structure is simpler, but the recording medium may interfere with the roller
Solution Approach 1:
The medium intake portion is positioned in a lower vertical position than the discharge roller, creating clear spatial separation in the vertical dimension. This positioning allows the recording medium to be received without interfering with the roller operation, maintaining both structural simplicity and functional integrity
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
Prevents contamination and damage to the recorded medium by ensuring non-contact with the discharge roller, while allowing for efficient handling and simplification of the recording medium cassette structure, reducing costs.
Implementation Method 1
the bottom of the holding unit may be disposed to decline away from the roller. According to the configuration, the sent recording medium automatically follows the bottom of the holding unit by the own weight
Implementation Method 2
the medium intake portion may be positioned vertically lower than the top of the roller. According to this configuration, the recording medium sent to the roller is delivered from the roller to the medium intake portion and then smoothly sent to the receiving unit along the medium intake portion

AI summary
A recording apparatus includes a holding unit that holds a recorded recording medium in a standing posture, a roller that sends the recording medium to the holding unit, and a restricting unit that restricts the position of the recording medium not to be in contact with the roller.
