Patent number: 11218622Abstract: An image capturing apparatus includes an electronic viewfinder unit that can shift between a retracted state where the electronic viewfinder unit is retracted in a main body portion of the image capturing apparatus and an extended state where the electronic viewfinder unit is extended from the main body portion. The electronic viewfinder unit includes a holding cover that holds a pivoting unit where the pivoting unit can be rotated centering on a pivot shaft, and a pivot latch member that latches in a pivoting unit pivoting operation. The pivoting unit includes an electronic display unit, an eyepiece portion, an eyepiece window to cover the eyepiece portion, and a lens holder to hold a finder lens that guides light emitted from the electronic display unit to the eyepiece portion. When the pivoting unit is being rotated, the pivot latch member regulates shifting of the electronic viewfinder unit to the retracted state.Type: GrantFiled: September 8, 2020Date of Patent: January 4, 2022Assignee: Canon Kabushiki KaishaInventors: Hidetoshi Kei, Keita Iwai, Shingo Iwatani, Ryoji Okuno
