Recording Medium Transport Rollers With Flexible Loop Release Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The generation of knocking sounds when a loop in a recording medium is released, as it directly knocks the guide member in existing transport devices, is a challenge.
Innovation Solution
A transport device with a positioning roller, pressing roller, guide member, and flexible member configuration that forms a loop, separates the flexible member from the recording medium, and uses a flexible member to guide the released loop, reducing direct contact and noise generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide member directly guides the recording medium when the loop is released, then the recording medium can be transported smoothly, but a knocking sound is generated due to direct contact
Solution Approach 1:
A flexible member is introduced as an intermediary element between the guide member and the recording medium. The flexible member contacts the recording medium when the loop is released, absorbing the impact and preventing direct contact between the recording medium and the rigid guide member, thereby eliminating the knocking sound while maintaining smooth transport
Solution Approach 2:
The flexible member is designed as a thin, flexible component that can deform elastically upon contact with the recording medium during loop release. This flexibility allows it to cushion the impact and reduce noise generation, while still providing effective guidance for the recording medium through the transport path
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
Suppresses the generation of knocking sounds and minimizes damage to the recording medium by using a flexible member to guide the released loop, enhancing the transport process.
Implementation Method 1
a flexible member that is flexible in a case of coming into contact with the recording medium in which the loop is released and is pressed against the guide member by the recording medium

AI summary
A transport device includes a positioning roller that positions a leading end of a recording medium; a pressing roller that presses the leading end of the recording medium against the stopped positioning roller to form a loop in the recording medium between the pressing roller and the positioning roller; a drive member that rotationally drives the stopped positioning roller to release the loop and transport the recording medium; a guide member that is disposed between the pressing roller and the positioning roller in a transport direction of the recording medium, is separated from the recording medium in which the loop is formed, and guides the recording medium in which the loop is released to a downstream side in the transport direction; and a flexible member that is flexible in a case of coming into contact with the recording medium in which the loop is released and is pressed against the guide member by the recording medium.
