Canon Patent For Built-In Tilting Viewfinder

Canon Patent

A new Canon Patent application describing a built-in tilting viewfinder which should also tale less space for implementation.

Canon patent application 2023104712 (Japan, published 7/28/2023) describes methods and technology for a tiltable viewfinder for an EOS R series camera body. From the patent literature:

[Title of the invention] Viewfinder unit, imaging device

Canon Inc. An object of the present invention is to suppress an increase in the size of an electronic device while securing a large rotation angle of a finder portion.

Description of the Related Art

Conventionally, a viewfinder unit provided in an electronic device such as an imaging device is known. For example, in an electronic device having a viewfinder unit such as an electronic viewfinder, the viewfinder unit is arranged on the upper part of the back side of the electronic device body. The finder section of the finder unit can be slid out from the main body of the electronic device, and the finder section can be tilted and rotated upward from the pulled out state, thereby increasing the degree of freedom in shooting posture.

However, in Patent Document 1, since the distance between the contact position of the pair of leaf springs with respect to the base plate and the rotation axis of the holder is long, the contact position moves so as to draw a large arc locus during rotation. . If the finder section rotates excessively, the leaf spring section will come off the fixed plate, so there is a restriction on the rotation angle of the finder section. On the other hand, if an attempt is made to design the rotation angle to be large, it is necessary to enlarge the fixing plate, which leads to an increase in the size of the imaging apparatus main body.


It is an object of the present invention to suppress an increase in the size of an electronic device while ensuring a large rotation angle of a viewfinder.
