Patent number: 11838612Abstract: An electronic view finder unit provided in an image pickup apparatus is movable between a retracted state in which the electronic view finder unit is retracted in a main body and a projecting state in which the electronic view finder unit projects from the main body. The electronic viewfinder unit includes a viewfinder having a display device, an eyepiece portion, and a lens holder. The eyepiece portion is slidable between an inserted position and an extracted position in the optical axis direction of the lens. At the position where, in the projecting state, the eyepiece portion is extracted, the viewfinder is rotatable around an axis orthogonal to the optical axis of the lens. Both during the rotating operation of the viewfinder and in a state in which the rotating operation has completed, the movement of the eyepiece portion from the extracted position to the inserted position is limited.Type: GrantFiled: December 15, 2021Date of Patent: December 5, 2023Assignee: Canon Kabushiki KaishaInventor: Hidetoshi Kei
