フアインダ装置。 In a single-lens reflex camera's finder device, which has a finder optical system that can be folded and stored inside the camera body, it has an eyepiece section that takes two stable positions, a storage position and an observation position, and an aperture in which a photographic lens and film are placed. is provided in the photographing optical path in between, facing the photographing lens, and when observing a subject, reflects the light incident through the photographing lens to the optical path toward the eyepiece through the viewfinder optical system;
A movable mirror that is retracted from the photographing optical path when photographing a subject or when the viewfinder optical system is folded; a fixed mirror that is provided outside the photographic optical path and reflects the subject light reflected by the movable mirror; and in the viewfinder observation state. , has an entrance surface that receives reflected light from the fixed mirror, and an exit surface that outputs the subject light incident on the entrance surface to the eyepiece lens, and when the viewfinder optical system is folded, the entrance surface is connected to the movable mirror. A roof mirror section is provided which assumes two stable positions: a storage position facing the rear surface and a window observation state, and when the window viewfinder optical system is in a folded state, the fixed mirror, the movable mirror, the roof mirror section, and the eyepiece section are arranged close to each other in this order. A finder device for a single-lens reflex camera characterized by being retractable.
