Imaging Apparatus Movement Restriction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in effectively restricting the movement of imaging elements to correct image shake and maintain optical axis alignment, particularly under varying conditions such as acceleration and power states.
Innovation Solution
The imaging apparatus incorporates a movement restriction mechanism with a first and second member that sandwich a sandwiching target member at multiple points, using a processor to control the movement restriction based on specific conditions like power state or detected acceleration, ensuring the imaging element's movement is restricted when necessary to prevent image shake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging element is allowed to move freely for image shake correction, then image quality during movement is improved, but image shake occurs during stationary operation
Solution Approach 1:
The movement restriction member dynamically switches between restricted and unrestricted states based on operation mode. During stationary operation, the first and second members sandwich the sandwiching target member to restrict movement. During image capture, the sandwiching is released to allow free movement for shake correction. This dynamic state change resolves the contradiction by adapting the restriction level to operational requirements.
2Device complexity
If the movement restriction member uses a simple sandwiching mechanism, then device complexity is reduced, but the precision of movement restriction deteriorates
Solution Approach 1:
The sandwiching target member features localized contact surfaces with specific geometric properties. The first and second members contact the target member at defined points, creating precise restriction zones. This localized quality approach achieves accurate movement restriction without requiring complex mechanisms throughout the entire structure.
Solution Approach 2:
The sandwiching target member serves as an intermediary element between the first and second members. This mediator component translates the sandwiching action into precise movement restriction of the imaging element, achieving high precision through the intermediary's geometric design rather than direct complex mechanisms.
3Speed
If the first and second members move simultaneously to sandwiching positions, then operation speed is improved, but the timing precision of sandwiching deteriorates
Solution Approach 1:
The first member reaches the sandwiching position before the second member. This preliminary action ensures that the imaging element is partially secured before the second member arrives, allowing for controlled timing of the complete sandwiching action. The staged approach maintains both speed and timing precision by preparing the restriction mechanism in advance.

AI summary
Provided is an imaging apparatus that includes a movement restriction member that mechanically sandwiches a movable member. The imaging apparatus includes the movable member that includes an imaging element, a support member that supports the movable member within a plane that intersects an optical axis of the imaging element, and a movement restriction member that includes a first member and a second member. The first member and the second member move between sandwiching positions at which the first member and the second member sandwich a sandwiching target member provided on the movable member and non-sandwiching positions separated from the sandwiching target member, and at the sandwiching positions, the first member and the second member sandwich the sandwiching target member at at least two or more points.
