Imaging Device Shutter Elastic Member Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face erroneous camera shake correction due to the transmission of impact forces from the shutter member to the camera shake correction unit, particularly when the shutter member moves, leading to reduced image resolution and other errors.
Innovation Solution
The implementation of an imaging device with elastic members disposed on both sides of an imaginary straight line passing through the center of gravity of the shutter, orthogonal to the optical axis, which supports the shutter member and absorbs impact forces, thereby reducing erroneous corrections in the camera shake correction unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shutter member moves to adjust light amount, then the shutter function is achieved, but impact force is transmitted to the camera shake correction unit causing erroneous correction
Solution Approach 1:
The patent introduces an elastic member as an intermediary between the shutter mechanism and the camera shake correction unit. This elastic member absorbs and isolates the impact force generated during shutter operation, preventing it from being transmitted to the camera shake correction unit. The mediator allows both the shutter to operate freely and the camera shake correction unit to function accurately without interference from shutter-induced vibrations.
2Productivity
If the shutter member moves rapidly, then exposure control is improved, but vibration and impact force increase causing image quality degradation
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing elastic members that are specifically designed to absorb impact forces before they can affect the imaging system. These elastic members are positioned to cushion the shutter mechanism's movements in advance, allowing rapid exposure control while simultaneously dampening vibrations and impact forces that would otherwise degrade image resolution.

Function Achieved in This Case
This configuration effectively suppresses the occurrence of erroneous corrections in the camera shake correction unit, maintaining image resolution and reducing vibration-related errors by absorbing impact forces and allowing controlled movement of the shutter member.
Implementation Method 1
a plurality of elastic members that are disposed on at least one side and the other side of an imaginary straight line passing through a center of gravity of the shutter and orthogonal to the optical axis

AI summary
An imaging device includes: an imager that is provided in a device body; a shutter that is provided in the device body, includes a support member and a shutter member; an actuator that is provided in the device body and moves the imager in a direction orthogonal to an optical axis to correct an amount of camera shake; and a plurality of elastic members that are disposed on at least one side and the other side of an imaginary straight line passing through a center of gravity of the shutter and orthogonal to the optical axis in a case where the plurality of elastic members are viewed in a direction of the optical axis and are in contact with the device body and the support member.
