Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face issues with unwanted vibration transmission to the exposure device, leading to malfunctions such as poor image quality due to resonance, particularly when anti-vibration members or non-contact structures are not adequately implemented.
Innovation Solution
The image forming apparatus incorporates an anti-vibration member interposed between the interval maintaining members and the exposure device, along with elastic members to suppress vibration transmission, and in some embodiments, employs gaps and additional anti-vibration members to further mitigate vibration propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the exposure device is directly supported by rigid structures, then structural stability is improved, but vibration transmission from external sources increases causing resonance and poor image quality
Solution Approach 1:
The patent introduces an anti-vibration member as an intermediary component between the exposure device and the support structure. This member serves as a mediator that physically connects the two while filtering out harmful vibrations, allowing structural support to be maintained without transmitting external vibrations to the exposure device.
Solution Approach 2:
The patent extracts the vibration isolation function from the structural support system by introducing a separate anti-vibration member. This separates the support function (provided by the rigid support structure) from the vibration transmission function (blocked by the anti-vibration member), allowing each to optimize its specific role.
2Object-affected harmful factors
If anti-vibration members are interposed between the support structure and exposure device, then vibration transmission is reduced, but device complexity increases
Solution Approach 1:
The patent applies the anti-vibration member only at the specific location where the exposure device contacts the support structure, rather than throughout the entire system. This localized application provides vibration isolation where needed without adding complexity to other parts of the system.
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
This configuration effectively reduces and eliminates vibration transmission to the exposure device, preventing resonance and improving image quality by maintaining stable operation of the exposure device.
Implementation Method 1
an anti-vibration member is interposed between the interval maintaining member and a contact portion of the exposure device
Implementation Method 2
an anti-vibration member is interposed between the interval maintaining member and a contact portion of the exposure device

AI summary
An image forming apparatus includes: a rotatable photoconductor; an exposure device that forms a latent image by radiating light from a light emitting element disposed along an axial direction of the photoconductor, an interval maintaining member that maintains an interval between the photoconductor and the exposure device; and a support member to which at least the photoconductor and the exposure device are attached, in which an anti-vibration member is interposed between the interval maintaining member and a contact portion of the exposure device.
