Movable Electronic Viewfinder Retractable Housing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing apparatuses with turnable electronic viewfinders protrude from the main body, affecting portability when not in use and limiting the degree of freedom in image capturing attitudes during use.
Innovation Solution
An electronic apparatus with a movable and retractable electronic viewfinder unit that includes a display, eyepiece, and lens holder, featuring a guide member and turning mechanism to transition between housed and protruding states, allowing for improved portability and operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic viewfinder constantly protrudes from the main body to enable image capturing, then the degree of freedom of image capturing attitude is improved, but portability deteriorates
Solution Approach 1:
The electronic viewfinder is designed to be movable between a protruding state (when in use) and a retracted state (when not in use) through a turning mechanism. This dynamic configuration allows the device to adapt its form based on operational needs, improving portability when retracted while maintaining adaptability when protruding for image capturing
Solution Approach 2:
The electronic viewfinder unit is housed within the main body of the image capturing apparatus when not in use, similar to a nested doll structure. The viewfinder can be turned and extended from the main body when needed, allowing compact storage while maintaining full functionality during operation
2Volume of moving object
If the electronic viewfinder is made movable and retractable to improve portability, then portability is improved, but device complexity increases
Solution Approach 1:
The electronic viewfinder system is divided into distinct functional components: the viewfinder unit itself, the turning mechanism, the guide member, and the holding portion with first and second holding members. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving the desired movability and retractability
Solution Approach 2:
A turning member acts as an intermediary component between the holding portion and the viewfinder unit, enabling the viewfinder to rotate about an axis orthogonal to the optical axis. This intermediary mechanism facilitates smooth movement and positioning without requiring complex direct coupling between components

AI summary
An electronic viewfinder unit includes a finder unit and a base member. The finder unit includes a display unit, an eyepiece portion, and a lens holding member holding a lens that guides a light flux emitted from the display unit to the eyepiece portion. The base member includes a guide member configured to guide the electronic viewfinder unit to a housed state and a protruding state. The base member includes a holding portion and a turning member. The holding portion is provided with a first holding member and a second holding member that face each other with an optical axis of the lens in between. The turning member has one end held by the first holding member and another end held by the second holding member, and is turnable about an axis orthogonal to the optical axis of the lens.
