Recording Medium Support Timing to Prevent Flapping in Image Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recording medium flaps when the support of the other surface starts after the rear end is separated from the transport body during transport, leading to potential interference and reduced material flexibility.
Innovation Solution
The support of the recording medium's other surface is initiated before the rear end separates from the transport body, using an air blowing mechanism to maintain a non-contact state and stabilize the medium's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the support of the other surface of the recording medium is started after the rear end is separated from the transport body, then the transport part can complete its transport function, but the recording medium flaps and stability deteriorates
Solution Approach 1:
The support part starts supporting the other surface of the recording medium before the rear end is completely separated from the transport body. This preliminary action ensures that the recording medium is continuously supported during the transition phase, preventing flapping while maintaining transport efficiency.
2Stability of the object's composition
If the support part makes contact with the other surface of the recording medium, then support stability is improved, but interference with the transport part increases
Solution Approach 1:
The support part supports the recording medium through a non-contact mechanism (such as air blowing) rather than direct contact. This intermediary approach maintains support stability while avoiding interference with the transport part, as the support is delivered through a gap rather than physical contact.
3Object-generated harmful factors
If non-contact support is used for the recording medium, then interference is reduced, but material flexibility is limited
Solution Approach 1:
The support part uses air blowing (pneumatic force) to provide non-contact support for the recording medium. This allows the system to maintain reduced interference while supporting various material types, as the pneumatic force can be adjusted to accommodate different material properties without physical contact constraints.

Function Achieved in This Case
This configuration suppresses flapping and reduces interference, allowing for higher material flexibility and efficient transport.
Implementation Method 1
a support part that supports the other surface of the recording medium before the rear end of the recording medium is separated from the transport body as a result of transport by the transport part

AI summary
An image forming apparatus includes: an image forming part that forms an image at an image formation position on one surface of a recording medium; a transport part that transports the recording medium while holding a front end side of the recording medium so that the recording medium passes the image formation position; a transport body that transports the recording medium together with the transport part while supporting the other surface of the recording medium on which an image is to be formed by the image forming part; and a support part that supports the other surface of the recording medium, the support part starting the support before the other surface of the recording medium is separated from the transport body as a result of transport by the transport part.
